Information maintained by the Legislative Reference Bureau

Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the

ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the 

relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included

in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that 

has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and

you should refer to that Public Act to see the changes made to the current law.

(Text of Section from P.A. 97-106)

Sec. 13C-15. Inspections.

(a) Computer-Matched Inspections and Notification.

(1) The provisions of this subsection (a) are 

operative until the implementation of the registration 

denial inspection and notification mechanisms required by 

subsection (b). Beginning with the implementation of the 

program required by this Chapter, every motor vehicle that 

is owned by a resident of an affected county, other than a 

vehicle that is exempt under paragraph (a)(6) or (a)(7), is 

subject to inspection under the program.

The Agency shall send notice of the assigned 

inspection month, at least 15 days before the beginning of 

the assigned month, to the owner of each vehicle subject to 

the program. An initial emission inspection sticker or 

initial inspection certificate, as the case may be, expires 

on the last day of the third month following the month 

assigned by the Agency for the first inspection of the 

vehicle. A renewal inspection sticker or certificate 

expires on the last day of the third month following the 

month assigned for inspection in the year in which the 

vehicle's next inspection is required.

The Agency or its agent may issue an interim emission 

inspection sticker or certificate for any vehicle subject 

to inspection that does not have a currently valid emission 

inspection sticker or certificate at the time the Agency is 

notified by the Secretary of State of its registration by a 

new owner, and for which an initial emission inspection 

sticker or certificate has already been issued. An interim 

emission inspection sticker or certificate expires no later 

than the last day of the sixth complete calendar month 

after the date the Agency issued the interim emission 

inspection sticker or certificate.

The owner of each vehicle subject to inspection shall 

obtain an emission inspection sticker or certificate for 

the vehicle in accordance with this paragraph (1). Before 

the expiration of the emission inspection sticker or 

certificate, the owner shall have the vehicle inspected 

and, upon demonstration of compliance, obtain a renewal 

emission inspection sticker or certificate. A renewal 

emission inspection sticker or certificate shall not be 

issued more than 5 months before the expiration date of the 

previous inspection sticker or certificate.

(2) Except as provided in paragraph (a)(3), vehicles 

http://www.ilga.gov/legislation/ilcs/ilcs4.asp?...&SeqStart=144400000&SeqEnd=145900000&Print=True (4 of 29) [4/17/2012 10:16:19 AM]
625 ILCS 5/ Illinois Vehicle Code.

shall be inspected every 2 years on a schedule that begins 

either in the second, fourth, or later calendar year after 

the vehicle model year. The beginning test schedule shall 

be set by the Agency and shall be consistent with the 

State's requirements for emission reductions as determined 

by the applicable United States Environmental Protection 

Agency vehicle emissions estimation model and applicable 

guidance and rules.

(3) A vehicle may be inspected at a time outside of 

its normal 2-year inspection schedule, if (i) the vehicle 

was acquired by a new owner and (ii) the vehicle was 

required to be in compliance with this Act at the time the 

vehicle was acquired by the new owner, but it was not then 

in compliance.

(4) The owner of a vehicle subject to inspection 

shall have the vehicle inspected and shall obtain and 

display on the vehicle or carry within the vehicle, in a 

manner specified by the Agency, a valid unexpired emission 

inspection sticker or certificate in the manner specified 

by the Agency. A person who violates this paragraph (4) is 

guilty of a petty offense, except that a third or 

subsequent violation within one year of the first violation 

is a Class C misdemeanor. The fine imposed for a violation 

of this paragraph (4) shall be not less than $50 if the 

violation occurred within 60 days following the date by 

which a new or renewal emission inspection sticker or 

certificate was required to be obtained for the vehicle, 

and not less than $300 if the violation occurred more than 

60 days after that date.

(5) For a $20 fee, to be paid into the Vehicle 

 Inspection Fund, the Agency may inspect:

(A) A vehicle registered in and subject to the 

 emission inspections requirements of another state.

(B) A vehicle presented for inspection on a 

voluntary basis.

Any fees collected under this paragraph (5) shall 

not offset Motor Fuel Tax Funds normally appropriated for 

the program.

(6) The following vehicles are not subject to 

inspection:

(A) Vehicles not subject to registration under 

Article IV of Chapter 3 of this Code, other than 

vehicles owned by the federal government.

(B) Motorcycles, motor driven cycles, and 

motorized pedalcycles.

The Agency may issue temporary or permanent exemption 

stickers or certificates for vehicles temporarily or 

permanently exempt from inspection under this paragraph 

(6). An exemption sticker or certificate does not need to 

be displayed.

(7) According to criteria that the Agency may adopt, 

a motor vehicle may be exempted from the inspection 

requirements of this Section by the Agency on the basis of 

an Agency determination that the vehicle is located and 

primarily used outside of the affected counties or in other 

jurisdictions where vehicle emission inspections are not 

required. The Agency may issue an annual exemption sticker 

or certificate without inspection for any vehicle exempted 

from inspection under this paragraph (7).

(8) Any owner or lessee of a fleet of 15 or more 

motor vehicles that are subject to inspection under this 

Section may apply to the Agency for a permit to establish 

and operate a private official inspection station in 

accordance with rules adopted by the Agency.

(9) Pursuant to Title 40, Section 51.371 of the Code 

http://www.ilga.gov/legislation/ilcs/ilcs4.asp?...&SeqStart=144400000&SeqEnd=145900000&Print=True (6 of 29) [4/17/2012 10:16:19 AM]
625 ILCS 5/ Illinois Vehicle Code.

of Federal Regulations, the Agency may establish a program 

of on-road testing of in-use vehicles through the use of 

remote sensing devices. In any such program, the Agency 

shall evaluate the emission performance of 0.5% of the 

subject fleet or 20,000 vehicles, whichever is less. Under 

no circumstances shall on-road testing include any sort of 

roadblock or roadside pullover or cause any type of traffic 

delay. If, during the course of an on-road inspection, a 

vehicle is found to exceed the on-road emissions standards 

established for the model year and type of vehicle, the 

Agency shall send a notice to the vehicle owner. The notice 

shall document the occurrence and the results of the onroad exceedance. The notice of a second on-road exceedance 

shall indicate that the vehicle has been reassigned and is 

subject to an out-of-cycle follow-up inspection at an 

official inspection station. In no case shall the Agency 

send a notice of an on-road exceedance to the owner of a 

vehicle that was found to exceed the on-road emission 

standards established for the model year and type of 

vehicle, if the vehicle is registered outside of the 

affected counties.

(b) Registration Denial Inspection and Notification.

(1) No later than January 1, 2008, every motor 

vehicle that is owned by a resident of an affected county, 

other than a vehicle that is exempt under paragraph (b)(8) 

or (b)(9), is subject to inspection under the program.

The owner of a vehicle subject to inspection shall 

have the vehicle inspected and obtain proof of compliance 

from the Agency in order to obtain or renew a vehicle 

registration for a subject vehicle.

The Secretary of State shall notify the owner of a 

vehicle subject to inspection of the requirement to have 

the vehicle tested at least 30 days prior to the beginning 

of the month in which the vehicle's registration is due to 

expire. Notwithstanding the preceding, vehicles with 

permanent registration plates shall be notified at least 30 

days prior to the month corresponding to the date the 

vehicle was originally registered. This notification shall 

clearly state the vehicle's test status, based upon the 

vehicle type, model year and registration address.

The owner of each vehicle subject to inspection shall 

have the vehicle inspected and, upon demonstration of 

compliance, obtain an emissions compliance certificate for 

the vehicle.

(2) Except as provided in paragraphs (b)(3), (b)(4), 

http://www.ilga.gov/legislation/ilcs/ilcs4.asp?...&SeqStart=144400000&SeqEnd=145900000&Print=True (7 of 29) [4/17/2012 10:16:19 AM]
625 ILCS 5/ Illinois Vehicle Code.

and (b)(5), vehicles shall be inspected every 2 years on a 

schedule that begins in the fourth calendar year after the 

vehicle model year. Even model year vehicles shall be 

inspected and comply in order to renew registrations 

expiring in even calendar years and odd model year vehicles 

shall be inspected and comply in order to renew 

registrations expiring in odd calendar years.

(3) A vehicle shall be inspected and comply at a time 

outside of its normal 2-year inspection schedule if (i) the

plates shall be inspected every 2 years on a schedule that 

begins in the fourth calendar year after the vehicle model 

year in the month corresponding to the date the vehicle was 

originally registered. Even model year vehicles shall be 

inspected and comply in even calendar years, and odd model 

year vehicles shall be inspected and comply in odd calendar 

years.

(6) The Agency and the Secretary of State shall 

endeavor to ensure a smooth transition from test scheduling 

from the provisions of subsection (a) to subsection (b). 

Passing tests and waivers issued prior to the 

implementation of this subsection (b) may be utilized to 

establish compliance for a period of one year from the date 

of the emissions or waiver inspection.

(7) For a $20 fee, to be paid into the Vehicle 

 Inspection Fund, the Agency may inspect:

(A) A vehicle registered in and subject to the 

 emissions inspections requirements of another state.

(B) A vehicle presented for inspection on a 

voluntary basis.

Any fees collected under this paragraph (7) shall not 

offset Motor Fuel Tax Funds normally appropriated for the

inspection month, at least 15 days before the beginning of 

the assigned month, to the owner of each vehicle subject to 

the program. An initial emission inspection sticker or 

initial inspection certificate, as the case may be, expires 

on the last day of the third month following the month 

assigned by the Agency for the first inspection of the 

vehicle. A renewal inspection sticker or certificate 

expires on the last day of the third month following the 

month assigned for inspection in the year in which the 

vehicle's next inspection is required.

The Agency or its agent may issue an interim emission 

inspection sticker or certificate for any vehicle subject 

to inspection that does not have a currently valid emission 

inspection sticker or certificate at the time the Agency is 

notified by the Secretary of State of its registration by a 

new owner, and for which an initial emission inspection 

sticker or certificate has already been issued. An interim 

emission inspection sticker or certificate expires no later 

than the last day of the sixth complete calendar month 

after the date the Agency issued the interim emission 

inspection sticker or certificate.

The owner of each vehicle subject to inspection shall 

obtain an emission inspection sticker or certificate for 

the vehicle in accordance with this paragraph (1). Before 

the expiration of the emission inspection sticker or 

certificate, the owner shall have the vehicle inspected 

and, upon demonstration of compliance, obtain a renewal 

emission inspection sticker or certificate. A renewal 

emission inspection sticker or certificate shall not be 

issued more than 5 months before the expiration date of the 

previous inspection sticker or certificate.

(2) Except as provided in paragraph (a)(3), vehicles 

shall be inspected every 2 years on a schedule that begins 

either in the second, fourth, or later calendar year after 

the vehicle model year. The beginning test schedule shall 

be set by the Agency and shall be consistent with the 

State's requirements for emission reductions as determined 

by the applicable United States Environmental Protection 

Agency vehicle emissions estimation model and applicable 

guidance and rules.

(3) A vehicle may be inspected at a time outside of 

its normal 2-year inspection schedule, if (i) the vehicle 

was acquired by a new owner and (ii) the vehicle was 

required to be in compliance with this Act at the time the 

vehicle was acquired by the new owner, but it was not then 

in compliance.

the binding arbitration process established by the 

contractor and accepted by the Agency, or in circuit court.

(11) The Agency's review of the adequacy and 

completeness of the contractor's proposed resolution of a 

damage claim is not binding upon the vehicle owner or the 

contractor and does not affect the rights of the vehicle 

owner or the contractor under law. The Agency's review of 

the adequacy and completeness of the contractor's proposed 

resolution of a damage claim is not a final action subject 

to administrative review and is not subject to review by 

the Pollution Control Board or otherwise appealable.

with Title 40, Part 51, Section 51.361 of the Code of 

Federal Regulations, the Agency and the Secretary of State 

shall design, implement, maintain, and operate a 

registration denial enforcement mechanism to ensure 

compliance with the provisions of this Chapter, and 

cooperate with other State and local governmental entities 

to effectuate its provisions. Specifically, this 

enforcement mechanism shall contain, at a minimum, the 

following elements:

(A) An external, readily visible means of 

determining vehicle compliance with the registration 

requirement to facilitate enforcement of the program;

(B) A biennial schedule of testing that clearly 

determines when a vehicle shall comply prior to 

registration;

(C) A testing certification mechanism (either 

paper-based or electronic) that shall be used for 

registration purposes and clearly states whether the 

certification is valid for purposes of registration, 

including:

(i) Expiration date of the certificate;

(ii) Unambiguous vehicle identification 

information; and

(iii) Whether the vehicle passed or received 

a waiver;

(D) A commitment to routinely issue citations to 

motorists with expired or missing license plates, with 

either no registration or an expired registration, and 

with no license plate decals or expired decals, and 

provide for enforcement officials other than police to 

issue citations (e.g., parking meter attendants) to 

parked vehicles in noncompliance;

(E) A commitment to structure the penalty system 

http://www.ilga.gov/legislation/ilcs/ilcs4.asp?...&SeqStart=144400000&SeqEnd=145900000&Print=True (26 of 29) [4/17/2012 10:16:19 AM]
625 ILCS 5/ Illinois Vehicle Code.

requirement through the use of mandatory minimum fines 

(meaning civil, monetary penalties) constituting a 

meaningful deterrent and through a requirement that 

compliance be demonstrated before a case can be closed;

(F) Ensurance that evidence of testing is 

available and checked for validity at the time of a new 

registration of a used vehicle or registration renewal;

(G) Prevention of owners or lessors from avoiding 

testing through manipulation of the title or 

registration system; title transfers may re-start the 

clock on the inspection cycle only if proof of current 

compliance is required at title transfer;

(H) Prevention of the fraudulent initial 

classification or reclassification of a vehicle from 

subject to non-subject or exempt by requiring proof of 

address changes prior to registration record 

modification, and documentation from the testing 

program (or delegate) certifying based on a physical 

inspection that the vehicle is exempt;

(I) Limiting and tracking of the use of time 

extensions of the registration requirement to prevent 

repeated extensions;

(J) Providing for meaningful penalties for cases 

of registration fraud;

(K) Limiting and tracking exemptions to prevent 

abuse of the exemption policy for vehicles claimed to 

be out-of-state; and

(L) Encouraging enforcement of vehicle 

registration transfer requirements when vehicle owners 

move into the affected counties by coordinating with 

local and State enforcement agencies and structuring 

other activities (e.g., driver's license issuance) to 

effect registration transfers.

(Source: Amended at 35 Ill. Reg. 11268, effective June 28, 2011) 

Section 276.204 Steady-State Idle Exhaust Emissions Test Procedures 

a) Steady-State Idle Test 

The steady-state idle test may be substituted for the OBD test for those vehicles 

identified in Section 13C-25(d) of the Vehicle Emissions Inspection Law of 2005. 

The steady-state idle test consists of a first-chance idle mode test followed, if 

necessary, by a second-chance test. The second-chance test consists of a high 

idle preconditioned mode while in neutral or park, followed immediately by an 

idle mode. 

 

b) General Requirements 

1) Initial tests (i.e., those occurring for the first time in a vehicle's scheduled 

test cycle) shall be performed without repair or adjustment at the 

inspection facility prior to the test. 

2) Tests shall be performed with Agency-approved equipment that has been 

calibrated according to the quality procedures contained in Section 

276.602 of this Part. 

3) Vehicles with apparent leaks of fuel, oil, coolant, or exhaust shall not be 

tested. 

4) Vehicles with missing tail pipe sections that would prohibit full insertion 

of an analyzer probe shall not be tested. 
5) Vehicles shall be tested with their engines and emissions control systems 

at normal operating temperatures and not overheating (as indicated by 

gauge, temperature lamp, touch test on the radiator hose, and/or boiling 

radiator). 

6) Vehicles shall be tested without any accessories in operation. 

7) Vehicles must be operated during each mode of the test with the gear 

selector in neutral or park for the idle mode test and the high idle 

preconditioning mode. 

8) For vehicles with multiple tailpipes, separate test results from each tailpipe 

shall be numerically averaged for each pollutant sampled unless 

equipment capable of simultaneously sampling multiple tailpipes is 

utilized. 

c) Procedures 

1) The analysis of exhaust gas concentrations must begin 10 seconds after the 

applicable test mode begins. 

2) Exhaust gas concentrations must be analyzed at a minimum rate of once 

every 0.75 second. 

3) The measured value for the pass/fail determination shall be a simple 

running average of the measurements taken over 5 seconds. 

 

4) With the exception of those vehicles specified in subsection (c)(5) of this 

Section, the tachometer must be attached to the vehicle in accordance with 

the analyzer manufacturer's instructions. 

5) Vehicles that cannot continuously meet the engine speed requirements of 

subsection (e)(1)(B) of this Section within 30 seconds after initiation of 

the first-chance test shall be rejected upon verification of the proper 

operation and placement of the tachometer. If it is determined that the 

operation or placement of the tachometer is faulty, immediate corrective 

action shall be taken and the vehicle shall be retested in accordance with 

subsection (e) of this Section. 

 

6) If the engine speed falls outside the limits specified in subsection 

(e)(1)(B), (e)(2)(B) or (e)(2)(C) of this Section, as applicable, for more 

than 5 seconds in any one excursion, or 15 seconds over all excursions 

within a test mode, the mode timer shall be reset to zero and the mode 

restarted. 

7) For vehicles whose design prevents the monitoring of the engine rpm rate 
with a tachometer, the engine speed requirements of subsections (e)(1)(B), 

(e)(2)(B), and (e)(2)(C) of this Section shall not apply. The 

preconditioning mode of a second-chance idle test shall consist of 

accelerating the vehicle's engine to an estimated rate of 2500 rpm for a 

period of 30 seconds prior to initiating a second-chance idle mode test. 

8) The sample probe must be inserted into the vehicle's tailpipe to a 

minimum depth of 10 inches. If the vehicle's exhaust system prevents 

insertion to this depth, a tailpipe extension must be used. 

9) The measured concentration of CO plus CO2 must be greater than or equal 

to 6 percent or the vehicle will be rejected. 

10) If a vehicle's engine stalls at any time during the test sequence, the test 

shall be aborted and restarted. If after 3 attempts the test cannot be 

completed, the vehicle shall be rejected. 

d) Pass/Fail Determination 

 A pass or fail determination is made for each applicable test mode based on a 

comparison of the test standards contained in 35 Ill. Adm. Code 240.152 with the 

measured value for HC and CO as described in subsection (c) of this Section. A 

vehicle passes the test mode if any pair of simultaneous measured values for HC 

and CO are below or equal to the applicable test standards. A vehicle fails the test 

mode if the values for either HC or CO, or both, in all simultaneous pairs of 

values are above applicable standards. 

e) Test Sequence 

 The steady-state idle test consists of a first-chance test and a second-chance test. 

The first-chance test consists only of an idle mode. The second-chance test 

consists of a preconditioning mode followed immediately by an idle mode, and is 

performed only if the vehicle fails the first-chance test. 

1) First-Chance Test 

A) The test starts when the conditions specified in subsections 

(e)(1)(B) and (e)(1)(C) of this Section are met.

A pass or fail determination is made for the vehicle and the mode 

is terminated in accordance with subsections (e)(1)(C)(i) through 

(e)(1)(C)(iv) of this Section. 
i) The vehicle passes the idle mode and the test terminates on 

or before an elapsed time of 30 seconds, if the measured 

values are less than or equal to the applicable test standards 

as described in subsection (d) of this Section. 

ii) The pass/fail analysis shall continue beyond 30 seconds as 

long as emission readings are declining based upon 

comparison of the last 5 consecutive measured values. The 

vehicle passes the idle mode and the test is immediately 

terminated if, at any point between an elapsed time of 30 

seconds and 90 seconds, the measured values are less than 

or equal to the applicable test standards described in 

subsection (d) of this Section. 

iii) The vehicle fails the first-chance test if the provisions of 

subsection (e)(1)(A), (e)(1)(C)(i), or (e)(1)(C)(ii) of this 

Section are not met.

between 350 and 1300 rpm after high idle preconditioning. The 

minimum idle mode length is determined as described in 

subsection (e)(2)(D) of this Section. 

D) The pass/fail analysis begins after an elapsed time of 10 seconds. 

A pass or fail determination is made for the vehicle and the idle 

mode is terminated in accordance with the following: 
i) The vehicle passes the idle test and the test terminates on or 

before an elapsed time of 60 seconds if the measured values 

are less than or equal to the applicable test standards as 

determined by the procedure described in subsection (d) of 

this Section; 

ii) The vehicle fails the idle test and the test terminates if the 

provisions of subsection (e)(2)(D)(i) are not met within an 

elapsed time of 60 seconds.

SUBPART F: EQUIPMENT MAINTENANCE AND CALIBRATION 

Section 276.601 Steady-State Idle Test Equipment Maintenance 

All operators of exhaust gas analyzers shall conduct a preventive maintenance and quality 

control program consisting of the following elements: 

a) an HC hang-up check conducted prior to each test and after the last test of the 

day; HC hang-up shall not exceed 20 ppm HC prior to any test; 
b) visual inspection of all equipment prior to the first test of the day; 

c) performance of analyzer preventative maintenance (e.g., filter replacement, 

inspection and cleaning of probes, sample lines, water traps, etc.) according to 

manufacturer's recommended schedules and as needed; and 

d) all calibration and operating procedures specified in Section 276.602. 

(Source: Amended at 22 Ill. Reg. 18867, effective September 28, 1998) 

Section 276.602 Steady-State Idle Test Equipment Calibration 

All operators of steady-state idle exhaust test gas analyzers shall comply with the following 

calibration and operating procedures unless alternative procedures have been approved by the 

Agency: 

a) Exhaust gas analyzers shall be warmed up prior to each vehicle inspection, zero 

check, span check, or calibration. Analyzers shall be considered to be in a 

warmed-up condition once stabilized zero readings (readings stabilize for one 

minute within ±2 percent of full scale, low range on all 3 channels) are obtained. 

b) The analyzer shall conduct a zero and span check prior to each test. The span 

check shall include the HC, CO and CO2 channels, and the NO and O2 channels, 

if present. If zero and/or span drift cause the signal levels to move beyond the 

adjustment range of the analyzer, it shall lock out from testing. 

c) The system shall lock out from testing if sample flow falls below 3 percent of full 

scale, or causes system response time to exceed 13 seconds to 90 percent of a step 

change in input, whichever is less. 

d) A system leak check shall be performed within 24 hours before the test, and may 

be performed in conjunction with the gas calibration described in subsection 

(e)(1) of this Section. If a leak check is not performed within 24 hours or if the 

analyzer fails the leak check, the analyzer shall lock out from testing. The leak 

check shall be a procedure demonstrated to effectively check the sample hose and 

probe for leaks and shall be performed in accordance with good engineering 

practices. An error of more than +2 percent of the reading using low range span 

gas shall cause the analyzer to lock out from testing and shall require repair of 

leaks. 

e) Gas Calibration 

1) Analyzers must undergo a two-point calibration within 72 hours before 

each test unless changes in barometric pressure are compensated for 

automatically and statistical process control demonstrates equal or better 

quality control using different frequencies. Gas calibration shall be 

accomplished by introducing span gas that meets the requirements of 

subsection (e)(3) of this Section into the analyzer through the calibration 
port. If the analyzer reads the span gas within the allowable tolerance 

range (i.e., the square root sum of the squares of the span gas tolerance 

described in subsection (e)(3) of this Section and the calibration tolerance, 

which shall be equal to 2 percent), no adjustment of the analyzer is 

necessary. The gas calibration procedure shall correct readings that 

exceed the allowable tolerance range to the center of the allowable 

tolerance range. The pressure in the sample cell shall be the same with the 

calibration gas flowing during calibration as with the sample gas flowing 

during sampling. If the system is not calibrated, or the system fails the 

calibration check, the analyzer shall lock out from testing. 

2) A two point gas calibration procedure shall be followed. The span shall be 

accomplished at one of the following pairs of span points: 

A) Low 

300 – ppm propane (HC) 

1.0 – percent CO 

6.0 – percent CO2 

1000 – ppm nitric oxide (if equipped with NO) 

High 

1200 – ppm propane (HC) 

4.0 – percent CO 

12.0 – percent CO2 

3000 – ppm nitric oxide (if equipped with NO) 

B) Low 

0 – ppm propane (HC) 

0.0 – percent CO 

0.0 – percent CO2 

0 – ppm nitric oxide (if equipped with NO) 

High 

600 – ppm propane (HC) 

1.6 – percent CO 

11.0 – percent CO2 

1200 – ppm nitric oxide (if equipped with NO) 

3) The span gases used for the gas calibration shall be traceable to NIST 

standards within two percent and shall be within two percent of the span 

points specified in subsection (e)(2) of this Section. 

f) Other Checks 
In addition to the other periodic checks described in this Section, those described 

in subsections (f)(1) and (f)(2) of this Section shall also be used to verify system 

performance under the special circumstances described therein. 

1) Gas Calibration 

A) Each time the analyzer electronic or optical systems are repaired or 

replaced, a gas calibration shall be performed prior to returning the 

unit to service. 

B) Multi-point calibrations shall be performed every 6 months. The 

calibration curve is checked at 20 percent, 40 percent, 60 percent, 

and 80 percent of full scale, and must be adjusted or repaired if the 

specifications in Section 276.503 are not met. 

2) Leak Checks 

Each time the sample line integrity is broken, a leak check shall be 

performed prior to testing.

Section 276.603 Evaporative System Integrity Test Maintenance and Calibration 

a) Applicability 

Relevant parameters of the fuel cap pressure decay tester and leak flow testers 

shall be inspected according to the procedures contained in this Section. 

1) Pressure Decay Tester 

A) The fuel cap pressure decay tester shall be checked for integrity at 

the beginning of each operating day and after 5 hours of use each 

day. If, after the fuel cap attachment end of the pressure decay 

tester is capped and pressurized to between 14 and 28 inches of 

water, the pressure system changes more than 0.2 inches of water 

over 15 seconds, the pressure decay tester shall be removed from 

service. 

B) The pressure gauge for the pressure decay tester shall be checked 

on a weekly basis against a reference gauge. A pressure decay 

tester that has a deviation in the measured pressure exceeding 0.3 

inches of water shall be removed from service. 

2) Leak Flow Tester 

A) The accuracy of the leak flow tester shall be verified by testing and 

correctly identifying the passing and failing reference fuel caps at 

the beginning of each operating day. Reference fuel caps shall be 

stored in a dirt and dust free manner to prevent clogging and 

changes in flow rate. Reference fuel caps shall be stored at the 

same temperature as the leak flow fuel cap tester to provide 

accurate flow reference. 
B) Independent flow bench verification of the reference fuel caps and 

the internal flow standard orifice shall be conducted before initial 

usage and as recommended by the leak flow tester manufacturer or 

as suggested by analysis of quality control data. The bend flow 

verification results shall be traceable to NIST. 

C) The upstream filter for the leak flow tester shall be maintained in 

accordance with manufacturer's specifications. 

b) Any fuel cap leak flow tester or pressure decay tester that fails an inspection shall 

be removed from service until repaired and its accuracy verified.

OPINION AND ORDER OF THE BOARD (by C.A. Manning):

On August 21, 2000, the Illinois Environmental Protection Agency (Agency) filed with

the Board proposed amendments to the enhanced vehicle inspection and maintenance (I/M)

regulations at 35 Ill. Adm. Code 240. The Agency’s proposal was filed under Section 13B-20(a)

of the Vehicle Emissions Law of 1995 (Vehicle Emissions Law) (625 ILCS 5/13B-1 et seq.

(1998)). The Vehicle Emissions Law provides that Section 27(b) of the Environmental

Protection Act (Act) (415 ILCS 5/27(b) (1998)) and the rulemaking provisions of the

Administrative Procedure Act (APA) (5 ILCS 100/1-1 et seq. (1998)) “shall not apply to rules

adopted by the Board under this subsection.” 625 ILCS 5/13B-20(a) (1998). Additionally,

Section 13B-20(a) requires the Board to adopt rules within 120 days after it receives the

Agency’s proposal, that is, on or before December 19, 2000.

On August 24, 2000, the Board accepted the proposal for hearing and directed the

proposal be filed for publication in the Illinois Register as a proposal for public comment. The

proposal for public comment appeared in the Illinois Register on September 15, 2000, 24 Ill.

Reg. 13820.

The Board held two public hearings in this matter. The first hearing was held before

Hearing Officer Richard McGill on October 11, 2000, in Chicago, Illinois. The second hearing

was held before Hearing Officer Andrew Boron on October 20, 2000, in Collinsville, Illinois. At

both hearings the Agency offered testimony in support of its proposal. Specifically, the following

Agency personnel participated in the Board proceedings: Elizabeth R. Tracy, manager of the

Division of Vehicle Inspection and Maintenance, Bureau of Air; Christopher P. Demeroukas,

attorney, Bureau of Air; and James Matheny, manager of technical services in the Division of

Inspection and Maintenance, Bureau of Air. On November 9, 2000, the Agency filed public

comments (PC 1). The Board received no other testimony or public comments.

The Board today adopts amendments to 35 Ill. Adm. Code 240. The amendments include

changes to the proposal suggested by the Agency and the Joint Committee on Administrative

Rules, as well as a few other minor changes.

FEDERAL STATUTORY BACKGROUND

Sections 182(b) and (c) of the federal Clean Air Act (CAA) (42 U.S.C. §§ 7511(a), (b),

(c)) require states to implement vehicle “inspection and maintenance” (I/M) programs in areas

that do not meet National Ambient Air Quality Standards (NAAQS) for ozone or carbon

monoxide. Areas that do not meet NAAQS are referred to as “nonattainment” areas.

The CAA requires “basic” I/M programs in “moderate” and “marginal” ozone

nonattainment areas with exisiting I/M programs. It requires “enhanced” I/M programs in

“serious,” “severe,” and “extreme” ozone nonattainment areas with a population of 200,000 or

more. The CAA also requires states to submit, for the approval of the United States

Environmental Protection Agency (USEPA), revisions of their State Implementation Plans (SIPs)

that describe a satisfactory I/M program and assure that the I/M program will be implemented.

In Illinois, two areas do not meet the NAAQS for ozone: (1) the Chicago metropolitan

nonattainment area, which is a severe nonattainment area; and (2) the Metro-East St. Louis

nonattainment area, which is a moderate nonattainment area. Under the Vehicle Emission

Inspection Law, the Agency has proposed, and the Board has adopted an enhanced I/M program

for these two nonattainment areas in 35 Ill. Adm. Code 240. See Enhanced Vehicle Inspection

and Maintenance (I/M) Regulations: Amendments to 35 Ill. Adm. Code 240

(July 8, 1998), R98-24; (December 1, 1994), R94-20; (December 1, 1994), R94-19.

AGENCY PROPOSAL

The Agency proposes amendments to 35 Ill. Adm. Code 240 with respect to the enhanced

I/M program for the Chicago metropolitan and Metro-East St. Louis nonattainment areas. See

Agency Statement of Reasons at 3-4. The Agency describes its proposed changes as follows:

1. delaying the implementation of “pass/fail” on-board diagnostic testing from

January 1, 2001, to January 1, 2002;

2. retaining current, more lenient “start-up” hydrocarbon and carbon monoxide

emission standards for model year 1981 through model year 1986 light duty

vehicles, light duty trucks 1, and light duty trucks 2; and

3. adding several definitions, incorporating USEPA guidance by reference,

eliminating outdated provisions, and clarifying certain provisions. See Agency

Statement of Reasons at 3, 5-9, 11-13; Agency Summary of Testimony of

Elizabeth R. Tracy at 1-2.

The Agency describes these proposed changes as “relatively minor adjustments to the

Enhanced I/M program.” Agency Statement of Reasons at 5. The Agency states that it is

proposing the amendments “to enable Illinois to meet federal and state mandated enhanced

emissions testing requirements.” Id. at 3. The Agency also states that its proposal is “designed
3

to promote the acceptance of and adherence to the enhanced I/M program, and to refine certain

test requirements . . . .” Id. at 5.

THE ADOPTED AMENDMENTS

Federal regulations require the adoption by states of standards that result in a reduction of

vehicle emissions through testing procedures meeting, or exceeding, the amount of emissions

that would be reduced if its “model” I/M program design was implemented. USEPA requires

certain “design elements” to be a part of any enhanced I/M plan, but allows states to vary certain

program inputs as long as the plan achieves the same or greater reductions in emissions than

those required by USEPA’s applicable performance standard. The Board has adopted certain

required standards for Illinois’ enhanced I/M program, and the Agency has adopted certain

necessary procedural rules at 35 Ill. Adm. Code 276.

The amendments the Board is adopting today are designed to promote the acceptance of

and adherence to the enhanced I/M program, and to refine certain test requirements by retaining

current “start-up” emissions standards for certain categories of older vehicles, and by extending

for one year the implementation of “pass/fail” on-board diagnostic testing, and to make necessary

clarifications to the current rule.

Currently, the Agency’s emissions testing contractor is performing “advisory” on-board

diagnostic testing. This consists of attempting to gather information from 1996 and newer

vehicles presented for testing with on-board diagnsotic ports to determine if one or more

emissions control components or systems is not functioning properly and is in need of repair.

The testing is “advisory,” in that there is no consequence to a motorist whose vehicle fails a test.

Currently a motorist is simply notified whether his or her vehicle would have passed or failed had

the test been a mandatory part of the inspection. Once the “pass/fail” test becomes mandatory

rather than advisory, the consequence of failure can be as severe as suspension of either the

vehicle owners driving privileges or vehicle registration. Delaying the beginning of “pass/fail”

on-board diagnostic testing will allow the Agency to address problems with the acquisition and

analysis of data from certain vehicles’ on-board diagnostic ports.

The Agency notes the proposed beginning of “pass/fail” on-board diagnostic testing

should be “no later than January 1, 2002” instead of “January 1, 2002,” as referenced incorrectly

both in the statement of reasons and in the proposed amendatory text at proposed amendments to

Section 240.191. Exh. 1 at 1. At hearing, the Board expressed concern about the fairness to the

public of the “no later than” deadline of Section 240.191. Tracy testified the Agency would have

“an adequate public education and information program” prior to initiating the “pass/fail” onboard diagnostic testing. Tr. 1 at 23. The Board continues to have concerns and accordingly

adopts the rule as originally proposed. If the Agency is prepared to being “pass/fail” on-board

diagnostic testing prior to January 1, 2002, the Agency can propose a revision to the rule at that

time.

In response to Board questions, additional changes have been made to the rule for clarity

and for the workability of the program. Although a majority of the changes were minor, the
4

Board suggested one noteworthy change, which the Agency notes in PC 1. In response to Board

concerns regarding proposed amendments to 240.162 and 240.163, the Agency agrees that its

proposal in both these sections should be revised to include specific dates. PC 1 at 1-2. The

Agency suggests revising Sections 240.162 and 240.163 to read:

Section 240.162 Vehicle Exhaust Emission Start-Up Standards

Vehicle exhaust emission start-up standards contained in Section 240.Table A of this Part

shall apply for all vehicles subject to inspection until January 31, 2001. two years after

the beginning of IM240 testing. Beginning February 1, 2001, these standards shall

continue to apply to all model year 1981 through model year 1987 LDV, LDT1, and

LDT2 vehicles. All standards are expressed in grams per mile (gpm).

Section 240.163 Vehicle Exhaust Emission Final Standards

Beginning February 1, 2001, vehicle Vehicle exhaust emission final standards contained

in Section 240.Table B of this part shall apply for all vehicles subject to inspection

beginning at the conclusion of testing using the start up vehicle exhaust emissions

standards required in Section 240.162 except for model year 1981 through model year

1987 LDV, LDT1, and LDT2 vehicles, which shall continue to use the standards

contained in Section 240.Table A of this Part as described in Section 240.162. All

standards are expressed in grams per mile (gpm).

CONCLUSION

As previously discussed, Sections 182(b) and (c) of the CAA (42 U.S.C. §§ 7511a(b), (c))

require states to implement vehicle “inspection and maintenance” I/M programs in areas that do

not meet NAAQS for ozone or carbon monoxide. Accordingly, the Board adopts the suggested

amendments to 35 Ill. Adm. Code 240 to bring the Illinois I/M program into conformity with all

CAA requirements. The rules adopted today incorporate all of the Agency’s suggested changes.

In general, the Board finds that the Agency proposal and supporting documentation

demonstrates that the proposal will enable Illinois to: (1) meet federal and state mandated

enhanced emissions testing requirements, and (2) promote the acceptance of and adherence to the

enhanced I/M program. Specifically, the Board amends the rules to delay the implementation of

“pass/fail” on-board diagnostic testing from January 1, 2001 to January 1, 2002. The Board also

amends the rules to retain current, more lenient “start-up” hydrocarbon and carbon monoxide

emission standards for model year 1981 through model year 1987 light duty vehicles, light duty

trucks 1, and light duty trucks 2. Finally, the Board amends the rules by adding several

definitions, eliminating outdated provisions, and clarifying certain provisions. Changes

suggested by the Joint Committee on Administrative Rules have also been incorporated.

Agency in 35 Ill. Adm. Code 276. All standards are expressed as the cumulative grams for each

second of the composite and Phase 2 tests.

(Source: Amended at 24 Ill. Reg. , effective )

Section 240.165 Compliance Determination

a) Vehicle Exhaust Emission Start-Up and Final Standards - Compliance shall be

determined based upon the measurement of exhaust emissions while operating the

vehicle on a dynamometer and following the driving cycle as specified for the

transient IM240 test procedures adopted by the Agency. If the corrected,

composite emission rates exceed standards for any pollutant, additional analysis of

test results shall review the second phase ("Phase 2") of the driving cycle

separately. Phase 2 shall include second 94 through second 239 of the driving
14

cycle. Second-by-second emission rates in grams and composite emission rates in

grams per mile for Phase 2 and for the entire composite test shall be recorded for

each pollutant. For any given pollutant, if the composite emission level is at or

below the composite standard or if the Phase 2 grams per mile emission level is at

or below the applicable Phase 2 standard, then the vehicle shall pass the test for

that pollutant. Composite and Phase 2 emission rates shall be calculated in

accordance with procedures specified in "High-Tech I/M Procedures, Emissions

Standards, Quality Control Requirements, and Equipment Specifications: IM240

and Functional Evaporative System Tests, Revised Technical Guidance",

incorporated by reference at Section 240.107(c) 240.107 of this Part.

b) Vehicle Exhaust Emission Fast-Pass Standards - Compliance will be determined

based upon the measurement of exhaust emissions while operating the vehicle on

a dynamometer and following the driving cycle as specified for the transient

IM240 test procedures adopted by the Agency. Vehicles will be fast-passed using

the following algorithm:

1) Beginning at second 30 of the driving cycle, cumulative second-by-second

emission levels for each second, calculated from the start of the cycle in

grams, will be compared to the cumulative fast-pass emission standards

for the second under consideration. Beginning at second 109, fast-pass

decisions are based upon analysis of cumulative emissions in Phase 2, the

portion of the test beginning at second 94, as well as emission levels

accumulated from the beginning of the composite test.

2) A vehicle will pass the transient IM240 test for a given pollutant if either

of the following conditions occurs:

A) cumulative emissions of the pollutant are below the full cycle fastpass standard for the second under consideration; or

B) at second 109 and later, cumulative Phase 2 emissions are below

the Phase 2 fast-pass standards for the second under consideration.

3) Testing may be terminated when fast-pass criteria are met for all subject

pollutants in the same second.

4) If a fast-pass determination cannot be made for all subject pollutants

before the driving cycle ends, the pass/fail determination for each

component will be based on composite or Phase 2 emissions over the full

driving cycle according to the procedures in subsection (a) of this Section.

In cases where fast-pass standards are not used, composite emission rates

in grams per mile for Phase 2 and for the entire composite test will be

recorded for each pollutant.
15

5) Composite and Phase 2 emission rates will be calculated in accordance

with procedures specified in “High-Tech I/M Procedures, Emissions

Standards, Quality Control Requirements, and Equipment Specifications:

IM240 and Functional Evaporative System Tests, Revised Technical

Guidance” incorporated by reference at Section 240.107(c) 240.107 of this

Part.

Final Order. Adopted Rule.

OPINION AND ORDER OF THE BOARD (by R.C. Flemal):

On August 20, 2001, the Illinois Environmental Protection Agency (Agency) filed a 

proposal to amend the Board’s regulations on inspecting and maintaining vehicles to control air 

emissions. Today, the Board adopts amendments to 35 Ill. Adm. Code 240.191, 240.192 and 

240.193. The adopted rules contain most, but not all, of the Agency’s proposed changes.

BACKGROUND

Sections 182(b) and (c) of the federal Clean Air Act (CAA) (42 U.S.C §§ 7511a(b) and 

(c)) require states to implement vehicle “inspection and maintenance” (I/M) programs in areas 

that do not meet National Ambient Air Quality Standards (NAAQS) for ozone or carbon 

monoxide. Areas that do not meet NAAQS are referred to as “nonattainment” areas.

The CAA requires “basic” I/M programs in “moderate” and “marginal” ozone 

nonattainment areas with existing I/M programs. It requires “enhanced” I/M programs in 

“serious,” “severe,” and “extreme” ozone nonattainment areas with a population of 200,000 or 

more. The CAA also requires states to submit, for the approval of the United States 

Environmental Protection Agency (USEPA), revisions to their State Implementation Plans 

(SIPs) that describe a satisfactory I/M program and assure that the I/M program will be 

implemented.

In Illinois, two areas do not meet the NAAQS for ozone: (1) the Chicago metropolitan

nonattainment area, which is a severe nonattainment area; and (2) the Metro-East St. Louis 

nonattainment area, which is a moderate nonattainment area. Under Illinois’ Vehicle Emissions

Inspection Law of 1995 (Vehicle Emissions Law (625 ILCS 5/13B-1 et seq. (2000)), the Agency 

has proposed, and the Board has adopted, as amendments to 35 Ill. Adm. Code 240, an enhanced 

I/M program for these two nonattainment areas. See Enhanced Vehicle Inspection and

Maintenance (I/M) Regulations: Amendments to 35 Ill. Adm. Code 240 (July 8, 1998), R98-24; 

(December 1, 1994), R94-20; (December 1, 1994), R94-19.

The Agency’s proposal was filed under Section 13 B-20(a) of the Vehicle Emissions Law 

of 1995 (Vehicle Emissions Law). 625 ILCS 5/13-B-1 et seq. (2000). The Vehicle Emissions

Law provides that Section 27(b) of the Environmental Protection Act (Act) (415 ILCS 5/27(b) 

(2000)) and the rulemaking provisions of the Administrative Procedure Act (5 ILCS 100/1-1 et
2

seq.(2000)) “shall not apply to rules adopted by the Board under this subsection.” 625 ILCS 

5/13B-20(a) (2000). Section 13B-20(a) requires the Board to adopt rules within 120 days after it 

receives the Agency’s proposal, that is, on or before December 18, 2001. Adoption of these 

rules today fulfills the statutory mandate. 

On August 23, 2001, the Board accepted the proposal for hearing and directed the 

proposal be filed for publication in the Illinois Register as a proposal for public comment. The 

proposal for public comment appeared in the Illinois Register on September 7, 2001, 25 Ill. Reg. 

11328.

The Board held two public hearings in this matter. The first hearing was held on October 

12, 2001, in Collinsville, Illinois. The second hearing was held on October 19, 2001, in 

Chicago, Illinois. Both hearings were held before Hearing Officer John Knittle. At both 

hearings, the Agency was present to provide testimony in support of its proposal. The following 

Agency personnel participated in the Board proceedings: Elizabeth Tracy, manager of the 

Division of Vehicle Inspection and Maintenance Program, Bureau of Air; Michael Hills, 

Technical Services employee in the Vehicle Inspection and Maintenance Program; and James 

Matheny, Technical Service Manager of the Division of Vehicle Inspection Maintenance. No 

other testimony or public comments were filed in this matter. 

AGENCY PROPOSAL

 The Agency proposed amendments to 35 Ill. Adm. Code 240.191, 240.192, and 240.193. 

Specifically, the Agency stated that its proposal would revise 35 Ill. Adm. Code 240 by: 

 1. Revising the text of Section 240.191 to refer to the OBD procedural rules 

contained in 35 Ill. Adm. Code 276; 

2. Delaying mandatory “pass/fail” OBD testing to January 1, 2003, if the Agency 

chooses to apply to USEPA for this delay, and USEPA grants it; 

3. Modifying the list of diagnostic trouble codes (DTC) that, if identified during an 

OBD test, will result in a vehicle’s failure; 

4. Adding a malfunction indicator light (MIL) visual check, also known as a bulb 

check, to the OBD test; and 

5. Revising the text of Section 240.193 to clarify that the inspection of any vehicle 

fault codes actually consists of the electronic retrieval of those stored fault codes.

See Agency Statement of Reasons at 6-10. 

 The Agency described these proposed changes as “relatively minor adjustments to the 

Enhanced I/M program.” Agency Statement of Reasons at 5. The Agency states that it was 

proposing the amendments “to enable Illinois to meet federal and state mandated enhanced 

emissions testing requirements.” Id. at 3. The Agency also stated that its proposal was 

“designed to promote the acceptance of and adherence to the enhanced I/M program, by 
3

incorporating necessary ‘flexibility’ provisions for OBD testing as authorized by recent USEPA 

rulemaking and guidance.” Id. at 5.

THE ADOPTED AMENDMENTS

 Federal regulations require the adoption by states of standards that result in a reduction of 

vehicle emissions through testing procedures meeting, or exceeding, the amount of emissions 

that would be reduced if its “model” I/M program design was implemented. USEPA requires 

“design elements” to be a part of any enhanced I/M plan, but allows states to vary certain 

program inputs as long as the plan achieves the same or greater reductions in emissions that 

those required by USEPA’s applicable performance standard. The Board has adopted certain 

required standards for Illinois’ enhanced I/M program, and the Agency has adopted certain 

necessary procedural rules at 35 Ill. Adm. Code 276. 

 The amendments the Board is adopting today are designed to promote the acceptance of 

and adherence to the enhanced I/M program, and to refine certain test requirements by 

incorporating necessary ‘flexibility’ provisions for OBD testing as authorized by recent USEPA 

rulemaking and guidance. 

 Additional changes have been made to the rule for clarity and for the workability of the 

program. Although a majority of the changes were minor, the Board is making one noteworthy 

change, which the Agency agreed to at hearing. As proposed, the last sentence in Section 

240.191 would have delayed mandatory “pass/fail” OBD testing to January 1, 2003, if the 

Agency chooses to apply to USEPA for this delay, and USEPA grants it. At hearing, the Board 

expressed concerns that this change would create a situation where the date is extended only if 

two separate conditions are fulfilled, causing the potential problem that the public might not 

know whether the date had been extended. The Agency did not object to the removal of this 

provision, and the Board does not include this portion of the proposal in the adopted 

amendments. This sentence has been omitted from the adopted rules. 

CONCLUSION

 As previously discussed, Sections 182(b) and (c) of the CAA (42 U.S.C. Section 

751a(b),(c)) require states to implement vehicle “inspection and maintenance” I/M programs in 

areas that do not meet NAAQS for ozone or carbon monoxide. Accordingly, the Board addopts 

the suggested amendments to 35 Ill. Adm. Code 240 to bring the Illinois I/M program into 

conformity with all CAA requirements. As noted, the rules adopted to day incorporate each of 

the Agency’s suggested changes except the one delaying mandatory “pass/fail” OBD testing to 

January 1, 2003, if the Agency chooses to apply to USEPA for this delay, and USEPA grants it. 

 The Board finds that the Agency proposal and supporting documentation demonstrate 

that the proposal will enable Illinois to meet federal and state mandated enhanced emissions 

testing requirements, and promote the acceptance of and adherence to the enhanced I/M 

program.

If your vehicle failed an emissions test or was rejected for system monitors, please take a

few moments to review the information in this report. The Illinois Environmental Protection

Agency and the Air Team created this report to help you identify a repair shop that can 

diagnose and repair your vehicle and to answer frequently asked questions about 

the Illinois vehicle emissions test.

The Repair Shop Report Card (Report Card) is an indication of a shop’s ability to 

diagnose and repair vehicles that have not passed the emissions test. Each shop listed has 

a grade based on their ability to repair emissions systems. The grade is based on emissions

repair data and is calculated by dividing the number of successful emissions-related repairs by

the total number of emissions-related repairs done. Shops must have at least five emissions

repairs during six months and achieve a success rate of 75% or greater to appear in the 

Report Card. They are assigned a letter grade (A=93-100%, B=84-92%, and C=75-83%).

The report is updated quarterly. Shops are listed by grade, followed by number of repairs.

Although motorists are free to choose any repair shop, we recommend you consider

having your vehicle repaired by a qualified technician who is trained, experienced, and

equipped to repair emissions systems.

The repair of emissions systems has emerged as a specialty in automotive repair. Just as all

repair shops do not work on transmissions or do front-end alignments, not all repair shops

work on emissions. The diagnosis and repair of vehicles emissions systems can involve the

repair or replacement of multiple components and can be very challenging — even to 

veteran technicians. Be prepared to take the time necessary to discuss your vehicle’s test 

results, the shop’s repair procedures, and the potential costs involved.

CONTENTS

WHY SHOULD I READ THIS?

WHAT IS THE REPAIR SHOP REPORT CARD?

SUGGESTIONS ON HOW TO CHOOSE A REPAIR SHOP
When choosing a repair shop, it’s important to consider:

 Grades: The repair shop’s grades listed in this report. The higher the grade, 

the more success it has in repairing emissions systems.

 Number of Repairs: The volume of repairs performed by the repair shop, not just the grade. 

Large numbers of repairs and a high grade are generally more indicative of a skillful shop.

 Certified Technicians: Whether the shop employs a technician who is certified 

by the National Institute for Automotive Service Excellence (ASE).

 Industry Affiliations: Whether the shop has automotive industry affiliations, such as the 

Automotive Service Association (ASA) or the Alliance of Automotive Service Providers (AASP).

(Additional information about ASE, ASA, and AASP is provided later in the Report Card.)

Statistics indicate most emissions problems are not due to engine tune-up parts. The average

vehicle owner is probably unable to properly diagnose and repair emissions systems because

of the specialized training, experience, and equipment required to repair these modern 

vehicles. If your vehicle doesn’t run well, that problem certainly will need to be corrected first.

However, many vehicles that do not pass the emissions test appear to run well, yet have

higher than allowable exhaust and/or evaporative emissions. A series of inspections and 

diagnostics will be necessary before a solution can be determined.

In most cases, the repair shop will need to perform several steps just to know where to

start. They will need to interpret the Vehicle Inspection Report (VIR) that you received in the

test lane, road test the vehicle to check performance, and inspect the vehicle to verify all

emissions-control parts are operating as designed. They also will have the resources to 

research available factory and industry service bulletins and relevant warranty information.

That’s a lot for starters, but it avoids guesswork, mistakes and unneeded replacement 

of expensive components. Even then, this may not uncover the exact cause. These steps 

are intended to document conditions before the repair, and reveal systems or components

not functioning correctly. Additional testing may be required, and often more than one 

component or system may be at fault.

A number of repair shops may not be listed in the Report Card, possibly including the shop

you regularly use. You should feel free to ask your regular repair shop – or any shop – what

experience they have in repairing emissions systems, whether they completed formal training,

and membership in professional organizations. It is important you consider all available information before choosing a repair shop.

THE REPAIR PROCESS

ONCE YOU CHOOSE A REPAIR SHOP:

 Be sure to mention your vehicle failed or was rejected

for system monitors, and

 give the shop the Vehicle Inspection Report, and

 give the shop the Repair Data Form.

On-Board Diagnostics - Generation II

(OBD) is a complex computer system

installed on 1996 and newer cars and

light trucks, and 2008 and newer heavy

duty vehicles. This system is an early

warning of potentially high emissions.

How is the driver notified of a problem?

The driver is notified when a special lamp on

the dash called a Malfunction Indicator

Lamp (MIL) comes on. This light is reserved

for emissions control and monitoring

systems only. The MIL is turned on when

OBD finds a problem that could cause

emissions to exceed federal standards.

Which light is the MIL?

Automobiles use a variety of warning lamps

to notify drivers of different conditions.

However, in the case of the emissions MIL,

either the phrase

“Service Engine Soon,” or “Check

On-Board Diagnostics



problem and identify the proper repair.

Are OBD related repairs covered

by warranty?

Federal law requires that the emission

control systems on 1995 and later model

year vehicles be warranted for 2 years or

24,000 miles. Many automakers provide

extended warranty coverage beyond what

is currently required by federal law.

Federal law also requires that the onboard

computer and the catalytic converter on

1995 and later model year vehicles be 

warranted for 8 years or 80,000 miles.

Check with your repair facility, dealership 

or manufacturer for complete coverage.

System readiness monitors are part of a 

vehicle’s on-board computer.These monitors

test the OBD system and find problems.

When monitor test sequences are performed

and no problems are found, each monitor

will be set to a “ready” status.

If the test sequences are not performed, a

monitor will be in a “not ready” status and

may cause a reject at a testing station. 

In most cases, vehicles perform readiness

checks during normal driving. Your owner’s

manual may also contain helpful information

on preparing your OBD equipped vehicle for

an emissions test. However, when readiness

monitors do not set to “ready”, it is very

possible that something is preventing the

computer from monitoring the emissions

control system and the problem needs to

be diagnosed and repaired by a qualified

repair technician. 

If your vehicle did not pass the Illinois 

vehicle emissions test, it needs to be 

repaired and retested. These are some of

the questions most frequently asked by

owners. If you have any questions not listed

here, please speak to a customer service

representative at any full service station 

or your repair shop.

Engine,” is used, as in the following

examples:

Or, a standard symbol can be as in 

this example:

What does it mean if the MIL is on?

OBD turns the MIL on when it finds a

condition that may cause high engine or

evaporative emissions. In some cases, it

means that immediate service is needed

to prevent expensive damage and high

emissions. 

How is this test performed?

When a vehicle is brought into the

emissions station test lane, a connector is

attached to its OBD system, and the test

computer looks for problems that have

been identified by the OBD system.

What is checked when the OBD

test is performed?

The OBD system checks for any Diagnostic

Trouble Codes (DTC) that may have

illuminated the MIL and the status of 

Readiness Monitors.

What are the OBD test results used for?

The results of the OBD test helps repair

technicians to diagnose and repair the

vehicle’s emissions systems. The results

usually do not indicate the exact fix or

component failure but instead, direct the

technician to the probable area of concern.

What are Diagnostic Trouble Codes?

Diagnostic Trouble Codes (DTC) 

indicate which system or component

might be causing the problem. Even

though this is helpful to the repair

technician, diagnostic time charges will

generally be needed to isolate the




System Readiness Monitors

Frequently Asked Questions
Why did my vehicle fail the 

emissions test?

Your vehicle failed for one or more of the

following reasons:

 The check engine light has been

illuminated and Diagnostic Trouble

Codes are present indicating a

potential problem with the OBD 

system that could result in 

excessive emissions. 

 Your vehicle was unable to transmit

necessary information to our OBD

testing equipment.

Specific details for your test are printed

on the Vehicle Inspection Report. 

I maintain my car and it is running

fine, so why did it fail the test?

Generally, emission-control devices have 

little impact on the driveability of a vehicle.

Your vehicle may appear to be operating

fine but have an emissions system failure.

Even the best maintained vehicle might 

experience these types of failures.

Do I have to use a repair shop

listed in this Report Card?

No, but this Report Card is an informational

source that helps motorists to select a

repair shop that has been successful at 

diagnosing and repairing emissions related

problems.

Why is a “pre-existing condition”

a concern?

Vehicles are expected to perform as

designed during the emissions test. If a

vehicle has symptoms suggesting a

problem, operating the vehicle could cause

further damage and/or interfere with the

emissions test. A pre-existing condition

could also cause a part to fail during the

test due to age, wear, neglect or previous

damage. Care is taken to avoid problems

during the test, but motorists are ultimately

responsible for the condition and normal

operation of their vehicles. Vehicles that

cannot be operated safely during an 

emissions test are probably not safe to 

operate on the road. If you are in doubt

about the condition of your vehicle, you

should consider consulting a repair 

technician before an emissions test.

Why can’t a test station tell me what’s

wrong with my vehicle?

The test results provided to the lane 

inspectors do not provide diagnostic

information. Diagnostic work must be

completed by a qualified repair technician

to determine why the vehicle did not pass 

the emissions test.

What is a waiver?

A vehicle may qualify for a waiver for the

current test period if it has failed at least

two tests and fulfills all waiver requirements

listed on the Repair Data Form. Very few 

vehicles qualify for waivers. With proper

diagnosis and repair, most vehicles will

pass a retest before qualifying for a waiver.

Where do I take my vehicle to be

repaired and how can this Report Card

help me select a repair shop?

Although you are not required to do so, it is

strongly recommended you consider having

the vehicle repaired by a shop that has a

proven track record in diagnosing and 

repairing emissions related problems.

This report can be used to assist in the

selection of a repair facility. It contains the

business name, address and telephone

number of shops that have performed five

or more emissions repairs over a recent

six-month period. It indicates the number of 

repairs and a Grade.

Can I do my own repairs?

Yes, but today’s modern computer-controlled

vehicles present unique challenges to the

automotive repair industry. Emissions

generally require a higher degree

of training and expertise to diagnose

and repair — even for veteran technicians.

The typical vehicle owner could experience

considerable difficulty finding and repairing

the problem(s). It is also important to 

remember that repairs must be made 

by a recognized repair technician to count

towards a waiver.


Why does my repair shop

charge for diagnostic work when

I received a “Vehicle Inspection 

Report” at the emissions station?

The Vehicle Inspection Report gives your

technician the emissions test results for

your vehicle. The technician can use this 

information to help diagnose a problem(s)

that caused the vehicle to fail the test. The

report does not identify what component(s)

or system is causing the problem. While this

information is helpful to your technician, it

cannot pinpoint the actual repairs that must

be made. The technician uses this

information, training and experience, 

and a variety of diagnostic equipment to 

determine what repairs will be needed.

I had repairs made to my vehicle,

what do I do now?

Have the shop that performed the repair

complete the “Repair Data Form.” Then take

your vehicle to a test station for 

another test. Be sure to bring the completed

“Repair Data Form” and all receipts for the

emissions related repairs that were 

performed. Please note, if the shop submits 

the completed “Repair Data Form” 

electronically, you will not be required to 

provide this for your retest.

Do I have to go into the office

before I have my vehicle retested?

Not unless your vehicle failed or was 

rejected for OBD readiness for three or

more tests. After three or more

tests, a visual inspection of the vehicle

and review of repair receipts are required

before another test can be performed.

What if I can’t afford to have my

vehicle repaired right now?

You can apply for an Economic Hardship

Extension, which gives you more time to get

your vehicle fixed so it can pass the test or

receive a waiver. You must qualify for the

extension by meeting certain requirements

listed on the economic hardship extension

application form that is available at any

full service stations or call the Illinois EPA 

at 217/785-7449. The economic hardship

extension application is also available on the

Illinois EPA website at www.IllinoisAirTeam.com

Is there any consumer protection

available in Illinois?

Illinois law requires repair shops to make

specific disclosures to consumers and

prohibits certain unlawful practices. 

For additional information you may contact

the Illinois Attorney General’s office at

312-814-3000 or 800-386-5438 in

Chicago, or 618-529-6400 or 

800-243-0607 in the Metro East 

St. Louis area.

Vehicles can be rejected from the test

lanes for a variety of reasons. Generally,

there is a problem with the vehicle that 

prevented a safe and proper emissions test

Some of the reasons vehicles are

rejected are as follows:

OBD monitor status (most common)

Vehicles that do not have a sufficient

number of monitors set to “ready” are

rejected because the OBD system has

not evaluated enough of the emissions

systems on that specific vehicle

to ensure a valid test. See the section

entitled “On-Board Diagnostics” for

further information about OBD systems,

readiness, and setting monitors.

OBD catalyst monitor status

Vehicles that fail an OBD test with

Diagnostic Trouble Codes for problems

with catalyst efficiency are rejected if they

return for a retest and the catalyst monitor

is “NOT READY.” In these cases, the

catalyst monitor must be “READY” at the

time of any retest. See the section entitled

“Understanding On-Board Diagnostics” for

further information about OBD systems,

readiness, and setting monitors.

Fluid leaks

Vehicles that actively leak more than a few

drops of fluids during a pretest inspection

of the vehicle are rejected because they

pose significant safety concerns. Fluid leaks

Why Vehicles are Rejected


may indicate a preexisting condition, pose a

risk of further damage, and can even pose 

a fire threat.

Overheating

Vehicles producing steam under the hood,

or showing HOT on a temperature gauge/

warning light, or are actively leaking coolant

are rejected because they pose safety 

concerns. Overheating may indicate a 

pre-existing condition, pose a risk of further

damage, and can even pose a fire threat.

Incomplete repair data

Vehicles are rejected for a re-test when

the Repair Data Form is not completed.

Complete repair data is required in order 

to perform a retest.

Damaged driver’s door

Vehicles are rejected if the driver’s door will

not open. Such a condition jeopardizes the

safety of the inspector during the test process.

Damaged steering column

Vehicles are rejected if they cannot be

shifted or started in a normal fashion.

Such a condition jeopardizes the safety

of the inspector during the test process.

Missing VIN

Vehicles are rejected if the vehicle

identification number cannot be located

on the vehicle. These vehicles cannot be

tested because inspectors cannot verify

that they are testing the correct vehicle.

Vehicle stalled

Vehicles are rejected that will not start in

the test lane. The vehicle must be turned

off during certain parts of the test. If they do

not re-start, the test cannot be completed.

Host computer offline

Vehicles are rejected when the emissions

test station host computer system is down,

unless the motorist provides an acceptable

source document, such as a vehicle 

emissions test notice. It is recommended

that motorists always bring their test notice to

the station, even though it is rarely needed.

Too early

Vehicles that are not eligible for a test

are rejected. This usually occurs when a

vehicle is brought in for a test before it

has been assigned a test month.

Vehicle exceeded three-test limit

After a vehicle has failed and/or been 

rejected from three tests, no further tests

will be granted unless the motorist provides

credible evidence that appropriate repairs

have been completed since the last test.

These repairs would have to indicate that

the vehicle may pass another test, and a

visual inspection may be performed to

ensure that all required emission-related

components are present on the vehicle.

Noise

Vehicles are rejected for abnormal engine

or drive train noises that may indicate 

significant mechanical problems exist.

These vehicles cannot be tested for safety

reasons and to prevent further damage to

the vehicle.

Blocked Diagnostic Link Connector

Vehicles are rejected for aftermarket 

devices that obstruct the diagnostic link

connector and prevent inspectors at testing

stations from performing the OBD test. 

If this occurs, please have the obstruction

removed prior to returning for a retest.

Important Information for Rejected Vehicles

Your vehicle’s On-Board Diagnostic “OBD” system shows that it is not ready to be tested

resulting in its being rejected. Vehicles contain several complex emissions components

and systems, each designed to reduce pollution. Vehicle computers are equipped with

several programs that monitor the performance of these emissions components and systems.

Readiness monitors are an essential feature of your vehicle’s OBD system. When set to

READY, they indicate emissions components and systems on your vehicle are ready to be

tested. A condition of NOT READY doesn’t necessarily mean that there is anything wrong

with the vehicle; it simply means that the vehicle hasn’t completed all of the self-tests to

determine if everything is working properly.

There are several reasons why a readiness monitor is NOT READY. The most common reasons

are a recently disconnected or replaced battery, or recent vehicle repairs or maintenance

where diagnostic trouble codes (DTCs) have been cleared by someone performing repairs on

your vehicle. In most cases, the readiness monitor self-test can be completed under normal

driving conditions which include a combination of local and highway driving.

What Do I Do Now?

FIRST REJECT

If this is the first time your vehicle has been rejected because of monitor NOT READY status,

it is recommended that the vehicle be driven for a week before attempting a retest. Your

owner’s manual may also contain helpful information on preparing your vehicle for an

emissions test.

SECOND REJECT

If this is the second time your vehicle has been rejected because of monitor NOT READY

status, it is strongly recommended that you seek assistance from a qualified repair

technician to help set the monitors to READY. There may be a problem with one or more

of the emissions control systems preventing it from completing the required self-tests.

THIRD REJECT

If your vehicle is rejected for a third time or more because of monitor NOT READY status,

you will be required to have your vehicle diagnosed and repaired by a qualified technician.

In order to be authorized to receive an additional test, you must provide proof that a repair

technician has properly diagnosed your vehicle and set the monitors to READY status.

EXECUTIVE SUMMARY 

Motor vehicles are a significant contributor to air pollution, specifically, ground level ozone. Periodic 

mandatory emissions inspection encourages vehicle owners to properly maintain their vehicles, and in 

doing so, reduce the levels of hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen 

(NOx) emissions contributing to the formation of ground level ozone. 

The federal Clean Air Act (CAA) requires states to implement and operate vehicle emissions 

inspection and maintenance (I/M) programs in ozone non-attainment areas. Failure to operate a 

federally approved I/M program can result in stringent sanctions, including loss of federal highway 

funding and new source offset sanctions. 

The Illinois Vehicle Emissions Test Program, administered by the Illinois Environmental Protection 

Agency (Agency) and the Illinois Secretary of State (SOS), started in 1986 with "basic" idle exhaust 

emission testing of vehicles registered in portions of the Northeastern Illinois and Metro East St. 

Louis ozone nonattainment areas. In 1999, the program was modified to meet the requirements of the 

1990 amendments to the CAA, including the use of the IM240 loaded-mode exhaust emissions test 

and the gas cap pressure test. In 2004, Illinois replaced the IM240 emissions test with the on-board 

diagnostic (OBD) test on 1996 and newer vehicles equipped with OBDII technology. On February 1, 

2007, Illinois exempted all pre-1996 model year vehicles from further testing and dropped the IM240 

test procedure. Also, at this time, all vehicles receiving an OBD test were no longer subject to the gas 

cap test. Any 1996 or newer vehicle not equipped with OBD technology (most heavy-duty vehicles) 

were required to pass an idle exhaust and gas cap test. 

Beginning May 1, 2008, the contract to operate a new OBD/Idle inspection station network 

transferred from Envirotest Illinois, Inc. (EII) to Applus+ Technologies, Inc (Applus+). The new test 

station network is a hybrid-centralized program which includes a mixture of centralized full-service 

and OBD-only test stations and decentralized OBD-only test and repair facilities. 

Vehicles registered in the emission test areas are required to be inspected once every two years 

beginning the fourth model year after they were manufactured. Starting October 1, 2007, the Agency 

moved from computer matching to registration denial enforcement (SOS denies registration 

renewal/application if the vehicle has not complied with the emissions test requirement). Vehicles are 

assigned for testing based on the license plate registration expiration month. Emissions test notices 

are mailed out to motorists approximately three months prior to registration expiration. 

In 2011, approximately 2.04 million vehicle emission tests were conducted in Illinois. During the 

reporting period, approximately 7.1% of the vehicles tested failed the initial inspection and required 

repairs. 

Owners of vehicles failing the inspection received a detailed inspection report containing diagnostic 

information and a booklet containing names and addresses of repair facilities that had demonstrated 

high success in performing emissions repairs. Vehicles passing the emissions inspection were issued 

an emissions compliance certificate indicating the next scheduled assigned test. 

The emissions testing program is a major component of Illinois’ ozone air quality control programs 

for the Northeastern Illinois and Metro-East St. Louis ozone nonattainment areas. In 2011, the 

program reduced on-highway motor vehicle emissions of ozone forming VOC emissions by 9 tons 

per day in Northeastern Illinois (9.0 percent reduction) and 1.0 tons per day in Metro-East St. Louis 

(8.0 percent reduction).

1 BACKGROUND 

1.1 Air Quality Problem in Illinois 

Since the implementation of comprehensive ambient air quality monitoring in the 1970s, 

portions of Illinois have exceeded the National Ambient Air Quality Standard (NAAQS) for 

ozone. Ozone impairs lung function causing chest tightness, coughing and wheezing, especially 

in the young the elderly and persons suffering from respiratory diseases such as asthma, 

bronchitis, and emphysema. Research indicates that approximately 3,700 premature deaths and 

thousands of medical emergencies are linked to exposure to ozone air pollution in the Chicago 

and Metro-East St. Louis areas each year. 

Ozone is not directly emitted but is formed in the atmosphere on warm summer days through 

chemical reactions primarily between hydrocarbons (HC), oxides of nitrogen (NOx), and carbon 

monoxide (CO). HC emissions from vehicles are generated from incomplete fuel combustion 

and fuel evaporation. HC, also known as volatile organic compounds (VOC), include toxic air 

pollutants such as benzene and formaldehyde both of which are classified as known carcinogens. 

CO is emitted from a vehicle’s exhaust as a result of incomplete fuel combustion. NOx is 

emitted from vehicles as a natural byproduct of fuel combustion and like HC, is a precursor to 

the formation of ozone. Illinois did not specifically test vehicles for excessive NOx emissions in 

2011 since Northeastern Illinois, under the 1-Hour ozone standard, was granted a NOx control 

waiver from USEPA in accordance with Section 182(f) of the CAA. 

Following adoption of the Clean Air Act (CAA) Amendments of 1990, Illinois’ ozone air quality 

was re-evaluated, and it was determined that the Chicago and Metro-East St. Louis metropolitan 

areas did not meet the 1-Hour ozone standard and were therefore designated as “nonattainment.” 

Based upon monitored ozone air quality, the Chicago area was classified as a “Severe” ozone 

nonattainment area and Metro-East St. Louis classified as a “Moderate” area.

 

In 2004, the USEPA designated both the Chicago and Metro-East Illinois areas as “moderate” 

ozone nonattainment areas under the newly established 1997 eight-hour ozone standard. Then in 

2007 the Illinois EPA requested that USEPA find that the Chicago nonattainment area attained 

the revoked 1-hour ozone National Ambient Air Quality Standard (NAAQS). USEPA made this 

determination on December 30, 2008 (73 FR 79652). In addition, the Illinois EPA has submitted 

a redesignation request to attainment for ozone under the 8-hour standard in Chicago and the 

Metro-East nonattainment areas. The data submitted by the Illinois EPA shows that the Chicago 

and Metro-East St. Louis nonattainment areas attained the 1997 8-hour ozone standard for the 

years 2008 through 2010. On December 22, 2011, the USEPA proposed to approve the 

redesignation request for the Illinois portion of the St. Louis, MO-IL nonattainment area to 

attainment for the 1997 8-hour ozone National Ambient Air Quality Standard (NAAQS) (76 FR 

79579). On February 9, 2012, the USEPA proposed to approve the redesignation request for the 

Illinois portion of the Chicago-Gary-Lake Illinois-Indiana ozone nonattainment area to 

attainment for the 1997 8-hour ozone NAAQS (77 FR 6743). 

In 2008, the USEPA adopted a more stringent 8-hour ozone NAAQS reducing the standard from 

0.08 ppm to 0.075 ppm . For the years 2008, 2009, and 2010, Chicago area air quality 

monitoring data shows attainment of the 2008 standard. However, for the period 2009, 2010, 

and 2011, there was a violation of the 2008 8-hour ozone standard at one monitor located in Lake 
4 

County, IL. The design value at this monitor is 0.076 ppm, 0.001ppb over the 2008 8-hour 

NAAQS. USEPA recently proposed to classify the greater Chicago area will be classified as a 

marginal nonattainment area (77 FR 8211). 

Based on ambient air monitoring concentrations collected during the years 2008, 2009, and 2010 

in the St. Louis, MO-IL nonattainment area, USEPA proposed that the area be designated as 

nonattainment for the 2008 8-hour ozone NAAQS. Ambient air quality monitoring in the Illinois 

portion (Madison, Monroe, and St. Clair Counties) of the St. Louis, MO-IL nonattainment area 

reflect that the highest three year design value measured was 0.072 ppm for Madison County. 

Thus, taken alone, monitors in the Illinois portion of the region indicate it attained the 2008 8-

hour ozone NAAQS. However, the West Alton monitor located in St. Charles County had a 

three year design value of 0.078 ppm leading to the designation of the entire region as 

nonattainment. 

1.2 Motor Vehicle Contribution 

Based on the most recent emissions inventory for Illinois, motor vehicles are a significant source 

of HC and CO emissions, contributing 20 percent of the total HC emissions and 40 percent of the 

total CO emissions in Northeastern Illinois. Figure 1.1 shows the distribution of HC emissions 

by major category.

On-road mobile sources include cars, trucks, buses and motorcycles, while non-road mobile 

sources are made up of aircraft, locomotive, construction, industrial and lawn and garden 

equipment. Point sources are larger industrial or manufacturing processes, which have received 

a permit to operate from the Agency. Area sources include small businesses such as gas stations 

and dry cleaners and include estimates of emissions from the use of paints and other consumer 

products.

During the 1990s, the United States Environmental Protection Agency (USEPA) adopted stricter 

motor vehicle emissions standards for new vehicles, especially targeting HC and CO emissions. 

However, due to the deterioration of the motor vehicle engine and emissions control system over 

time, the “typical” vehicle on the road emits three to four times the pollution generated by new 

cars. A significant fraction of these excess emissions are a direct result of the failure of owners 

to properly maintain their vehicles, or to otherwise ensure that emissions control systems are 

operating properly. Proper maintenance of vehicles and emissions controls reduces emissions, 

improves vehicle performance and fuel efficiency, and prolongs vehicle life. To encourage 

owners to maintain their vehicles, vehicle emissions I/M programs were made a required element 

of air quality programs in either ozone or CO nonattainment areas. In compliance with the CAA 

and applicable federal regulations, the Illinois Enhanced I/M Program identifies cars and trucks 

significantly exceeding federal emissions standards, and through their repair, reduces emissions 

and improves air quality. 

 
6 

1.3 Clean Air Act Emissions Testing Requirements 

The CAA requires the establishment of either "Basic" or "Enhanced" I/M programs in 

nonattainment areas, depending on the severity of the nonattainment problem. States are allowed 

to propose and implement their vehicle testing programs, so long as they meet CAA 

requirements, and the program is approved by the USEPA. The CAA provides stringent 

sanctions in the event a state does not meet its obligations; including the imposition of a 

federally-designed and implemented vehicle emissions testing program, 2 for 1 new source offset 

sanctions, and the loss of a state's federal highway funding. Enhanced I/M was required in 

Northeastern Illinois due to the “Severe” nonattainment classification of the area. Basic I/M was 

required in Metro-East St. Louis based upon the “Moderate” classification. With the adoption of 

the 8-Hour ozone standard, both Chicago and Metro-East were reclassified as “Moderate”. Given 

the transition from exhaust emissions testing to OBD, the difference between “Basic” and 

“Enhanced” I/M programs has blurred and the current Illinois program complies with both 

standards. 
7 

2 ILLINOIS' VEHICLE EMISSIONS TESTING PROGRAM 

2.1 History 

Initial “Basic” I/M Program – In June 1984, the Illinois General Assembly passed the Vehicle 

Emissions Inspection Law (625ILCS 5/13A), authorizing the implementation of the vehicle 

emissions inspection program. Basic I/M was performed in Illinois from May 1986 to 

February1999. The program consisted of a simple idle exhaust test designed to identify gross 

emitters (i.e., heavily polluting vehicles). This test, conducted annually on vehicles registered 

within specified test areas, met the federal standards in effect at the time, and was appropriate for 

the types of vehicles then in production. 

In 1992, in response to a need for additional emission reductions, the program was expanded 

geographically to include more of the Chicago nonattainment area and add emission component 

checks (for tampering/removal of catalytic converters, gas caps and fuel inlet restrictors). The 

combination of the exhaust test and emission control component verification allowed inspectors 

to better identify which vehicles needed to be repaired to reduce emissions of ozone-forming 

pollutants. Toward the end of the basic program, gas cap pressure testing was added to identify 

vehicles with either leaking or missing gas caps. This new test procedure targeted VOC 

emissions from vehicles with malfunctioning evaporative control systems. 

Enhanced I/M Program - In February 1999, the Agency implemented the Illinois Enhanced 

I/M Program, consisting of significant upgrades to the program designed to bring Illinois into 

compliance with the 1990 amendments to the federal CAA. These improvements included: 

Incorporating new test procedures, such as the IM240 transient mode exhaust test, the gas 

cap pressure test, and the vehicle on-board diagnostic (OBD) system test. 

Changing the test frequency to require vehicles to be tested biennially (once every two 

years). 

Expanding the geographic area of program coverage to include all federally-required 

urbanized portions of the ozone non-attainment areas. 

Changing waiver requirements to introduce the $450 minimum repair expenditure 

requirements of the federal CAA. 

Changing the model year coverage to increase the age in which vehicles were first 

required to be tested from two to four years. 

Through January 31, 2007, the program was authorized by the Illinois Vehicle Emissions 

Inspection Law of 1995 (625 ILCS 5/13B) and was operated under the emissions standards 

adopted by the Illinois Pollution Control Board (35 Ill. Adm. Code 240), and pursuant to Agency 

procedures (35 Ill. Adm. Code 276). 

The Illinois EPA awarded a contract to Envirotest Illinois, Inc. (EII) to design, build and operate 

the enhanced inspection station network through April 30, 2008. EII is a subsidiary of 

Environmental Systems Products of East Granby, Connecticut. 

Current I/M Program – The program was recently reauthorized by the “Vehicle Emissions 

Inspection Law of 2005” (625 ILCS 5/13C). Significant changes have been made to the program 

that include: 
8 

Beginning February 1, 2007: 

i) Model year 1995 and earlier models that were in compliance with the Illinois Vehicle 

Emissions Inspection Law of 2005 were exempted from further vehicle emissions 

testing. All vehicles in this category had been required to pass an idle exhaust and 

gas cap pressure test. 

ii) The IM240 test procedure was eliminated for all vehicles. 

iii) Gas Cap pressure testing was no longer required for 1996 and newer model year light 

duty vehicles and trucks that received a successful OBD inspection. The gas cap test 

is still required for model year 1996 and newer heavy-duty trucks and 1996 and 

newer light-duty vehicles and trucks that are forced to a fallback idle test. 

iv) The “Key on Engine off” (KOEO) test, or bulb check was eliminated from the OBD 

test procedure. 

Beginning January 1, 2008, the enforcement mechanism was converted from the 

computer-matching system to a vehicle registration denial based system. In preparation 

for this change, in October 2006, the Illinois Vehicle Emissions Test program began 

assigning vehicles that successfully complete the emissions test requirement based on the 

registration expiration date – not the previous assign date. Motorists received test 

notification based on the registration expiration date beginning with the October 2007 

mailing list. 

In addition, beginning May 1, 2008, the contract to operate the inspection station network 

transferred from EII to Applus+ Technologies, Inc (Applus+) of Chicago in June 2007. The 

new test station network is a hybrid-centralized program and consists of the following: 

12 Centralized Full-Service test-only stations (9 in Northeastern Illinois, 3 in Metro-East 

St. Louis) maintained and operated by Applus+. These stations are equipped to perform 

all required test procedures (i.e., OBD, Idle Exhaust and Gas Cap Pressure). 

5 Centralized OBD-Only test-only stations maintained and operated by Applus+ in 

Northeastern Illinois. These stations are only equipped to perform the OBD test 

procedure. 

36 Decentralized OBD-Only test lanes (33 in Northeastern Illinois, 3 in Metro-East St. 

Louis) located in and operated by either Meineke Care Centers, Inc., Car-X Auto Service 

Centers, or full service automotive dealerships. These stations are only equipped to 

perform the OBD test procedure. 

3 Self-Serve OBD-Only Test Kiosks (2 in Northeastern Illinois, 1 in Metro-East St. 

Louis). This pilot test kiosk allows a motorist to perform the OBD test procedure on a 

vehicle without the need of an inspector. All three kiosks opened to the public on 

February 22, 2010. 

Future I/M Program – Amendments to the “Vehicle Emissions Inspection Law of 2005” (625 

ILCS 5/13C) were signed into law on July 14, 2011 ((Illinois Public Act (“P.A.”) No. 97-0106)). 

These amendments contain significant changes to the program that, beginning February 1, 2012, 

include: 

Eliminating the steady-state idle mode exhaust test 
9 

Eliminating the evaporative system integrity test (also known as the gas cap test). 

Exempting pre-2007 model year heavy-duty vehicles with gross vehicle weight rating 

(GVWR) between 8,501 and 14,000 pounds. 

Exempting all heavy-duty vehicles with GVWR greater than 14,000 pounds. 

Adding a visual inspection test for vehicles where OBD testing is not possible due to the 

vehicle’s design. 

2.2 Enhanced I/M Program Description 

Test Areas and Network - In Illinois, vehicle emissions testing is limited to vehicles registered 

within the urbanized portions of the Chicago and Metro-East St. Louis ozone non-attainment 

areas. In Chicago, this includes Cook, Du Page and Lake Counties; and portions of McHenry, 

Kane, Will and Kendall Counties. In the Metro-East St. Louis area, this includes portions of 

Madison, St. Clair and Monroe Counties. Testing areas are defined by ZIP Code and correspond 

more or less to the Urbanized Areas required by the CAA to be covered by an I/M program. 

As stated in Section 2.1, beginning May 1, 2008 the test-only centralized network was converted 

to a hybrid centralized configuration with 17 Centralized test-only facilities (14 in Chicago – 3 in 

Metro-East St. Louis) and 36 decentralized test and repair stations (33 in Chicago – 3 in MetroEast St. Louis, See Figures 2.1 and 2.2). 

 Figure 2.1 Figure 2.2 

 
10 

Test Requirements and Procedures - The purpose of the enhanced vehicle emissions test is to 

identify vehicles that emit excessive amounts of ozone precursors HC, CO and NOx. Once these 

vehicles are identified, vehicle owners are required to make repairs that will reduce the amount 

of exhaust and/or evaporative emissions to within acceptable levels. 

Until February 1999, the Illinois I/M program relied primarily on the use of the idle exhaust test 

to identify gross emitting vehicles. The idle test consists of measuring exhaust HC and CO while 

the vehicle is idling. Idle exhaust testing evolved from engine tune-up procedures used on 

late1960s and 1970s vehicles. On the carburetor-equipped vehicles of that era, repairs 

performed to reduce idle exhaust concentrations generally produced similar effects during road 

use. 

However, the introduction of sophisticated emissions and engine controls, particularly the advent 

of computer controls, limited the effectiveness of idle tests. Beginning with the 1996 model 

year, vehicles have been required by USEPA to be equipped with second-generation on-board 

diagnostics systems (OBD-II). These systems are designed to monitor major engine and 

emissions control systems continuously during vehicle operation, alerting the driver of 

malfunctions causing or contributing to exhaust or evaporative emissions exceeding federal 

standards. The systems also capture and store information useful to repair technicians in 

diagnosing and repairing the problem identified. The OBD I/M test consists of determining if 

the vehicle’s OBD system is properly functioning, and retrieving data stored in the OBD 

system’s computer memory. If it is determined that the vehicle’s malfunction indicator lamp 

(MIL) is illuminated and diagnostic trouble codes are present, or if the OBD system is missing, 

damaged, or inoperative, the vehicle will fail the test. OBD I/M testing is a required component 

of all I/M programs and is designed to replace the traditional exhaust tests on 1996 and newer 

vehicles. Most states have fully integrated OBD testing into their I/M programs. In Illinois, the 

OBD I/M test was phased-in over an 18 month period, with full implementation completed in 

January 2004. 

Starting February 1, 2007, most 1995 and earlier model year vehicles were exempted from 

further emissions testing and the IM240 test procedure was eliminated. With the aging of the 

vehicle fleet, it was decided that the State’s resources could be better utilized by focusing on the 

largest portion of the fleet. All 1996 and newer model year light-duty vehicles and trucks that are 

OBDII equipped are subject to the OBD inspection. All 1996 and newer heavy-duty vehicles not 

meeting the OBDII requirement are required to pass an idle exhaust and gas cap pressure test. 

Test Frequency and Vehicles Subject to Testing – Illinois operates a biennial vehicle 

emissions test program, meaning a vehicle is required to be inspected every 2 years on a 

schedule that begins in the fourth calendar year after the vehicle model year. Prior to February 1, 

2007, the emissions test requirement applied to 1968 and newer model year gasoline-powered 

motor vehicles registered in the test area, including passenger cars, sport utility vehicles 

(SUV’s), light and heavy-duty trucks and buses. However, starting February 1, 2007, all pre1996 model year vehicles that were currently in compliance with the Illinois Vehicle Emissions 

Inspection Law of 2005 were exempted from further emissions testing. In addition, all dieselpowered vehicles, show cars, ceremonial vehicles, and vehicles registered as antiques are exempt 

from testing. 

On Board Diagnostic Testing - The test consists of connecting an OBD system scan tool to the 

standardized connector port under the dash. With the engine running, the scan tool accesses the 
11 

on-board computer and retrieves specific information from the vehicle. This includes an 

indication of whether or not the MIL is commanded to be illuminated, the number of diagnostic 

trouble codes (DTC) stored in the system, the DTC codes, and the operational status of up to 

eleven systems monitored by the OBD system. 

Prior to the scan, the inspector performed a “bulb check” of the MIL to ensure that it is operating 

properly. Beginning February 1, 2007, the “bulb check” was no longer a required part of the 

Illinois OBD test procedure, except in cases where, due to vehicle design an OBD test cannot be 

conducted due to communication issues. 

Beginning October 15, 2009, vehicles with known OBD communication issues receive a fallback 

bulb/MIL check. Vehicles pass this fallback inspection if the check engine light illuminates 

during a key-on-engine-off position and does not illuminate during a key-on-engine-on position. 

During the 2011 reporting period, this fallback procedure was only available for the 1997 Acura 

2.5 TL, 2000 Nissan Altima, and the 2006 Mercedes C230/C280.

Idle Exhaust Testing – Prior to February 1, 2007, all model year 1968 through 1980 vehicles, 

and heavy-duty trucks (regardless of model year) received an idle exhaust test. This test was 

also used on 1981 and newer vehicles that could not be tested on the dynamometer (i.e. vehicles 

with full-time four-wheel drive and/or traction control). 

Beginning February 1, 2007, most pre-1996 model year vehicles were exempted from the vehicle 

emissions testing requirement. Therefore, the idle exhaust test will only be used for the following 

vehicles: 

1996 and newer heavy-duty vehicles that are not OBDII compliant; 

1996 and newer light-duty vehicles and Trucks that are forced to a fallback exhaust test; and, 

Pre-1996 model year vehicles that had failed to achieve compliance before February 1, 2007.

The test is performed while the vehicle is idling. A sampling probe is placed in the tailpipe to 

measure the concentrations of hydrocarbons and carbon monoxide in the vehicle’s exhaust. 

Measured values are compared against idle emissions standards established for the model year 

and type of vehicle tested. Vehicles are given two chances to pass the exhaust test. If the 

vehicle fails the initial test, the vehicle is preconditioned (accelerated to 2500 RPM in neutral). 

The vehicle is then returned to idle and a second measurement is taken. 

As mentioned above, this test will be eliminated starting February 1, 2012, and all vehicles 

subject to this test procedure will be exempted from further vehicle emissions testing. 

Gas Cap Pressure Test Testing – The gas cap pressure test consists of removing the cap from 

the vehicle and using a pressure tester to ensure that the cap does not leak. This test was required 

on all 1968 and newer model year vehicles equipped with evaporative emissions control systems. 

Beginning February 1, 2007, the gas cap pressure test was no longer required for 1996 and newer 

model year light duty vehicles and trucks that receive a successful OBD inspection. 

As mentioned above, this test will be eliminated starting February 1, 2012, and all vehicles 

subject to this test procedure will be exempted from further vehicle emissions testing.

3 OPERATING STATISTICS 

3.1 Testing Volumes and Failure Rates 

During the 2011 reporting period, 

the Agency conducted 

approximately 2 million vehicle 

emissions tests. Annual test 

volumes since the implementation 

of the enhanced program are 

shown in Table 3.1. Test 

volumes for calendar year 2007 

and beyond have decreased based 

on changes made to the test 

program as a result of the Vehicle 

Emissions Inspection Law of 

2005. The primary change 

effecting test volumes was the 

exempting of all complying pre1996 model year vehicles. 

Table 3.2 provides additional 

details on initial test volumes, 

including the numbers of passing 

and failing tests and the resulting 

failure rates. It is important to 

note that the current rates remain 

significantly below projected 

initial failure rates of 18-20%. 

The distribution of initial failures 

by vehicle model year for the 

2010-2011 test cycle is shown in 

Figure 3.1 on the following page. 

In calendar year 2011, 6.9% of 

vehicles failing the initial test 

failed for excessive exhaust/OBD 

and 7.7% failed the gas cap test. 

Of vehicles failing the exhaust emissions test (Idle), 98% exceeded HC emission limits, and 19% 

exceeded CO limits.

3.2 Emission Reductions 

Estimating overall program effectiveness requires the use of sophisticated computer modeling 

techniques to quantify the effect of the program on region-wide VOC and CO emissions from 

on-road sources. The Agency utilized the USEPA MOVES series of on-highway vehicle 

estimation models to generate 

Chicago and Metro-East St. Louis 

area-specific emission factors. 

These factors (typical or average 

VOC, CO and NOx emissions rates 

expressed in grams per mile) were 

applied to estimates of daily vehicle 

miles traveled (VMT) to calculate 

the total emissions generated in the 

nonattainment areas. Inputs to the 

model include area-specific data 

describing ambient conditions (e.g., 

temperatures, humidity), fuel composition, traffic composition (e.g., VMT mix by vehicle type 

and age), vehicle speed, and inputs defining the design of the I/M program. 

Current estimates of Illinois I/M 

program VOC emission reductions 

have been made using the 

MOVES2010a version of the model. 

Table 3.3 summarizes emission 

reduction estimates for the Chicago 

Nonattainment area. As shown, the 

current Illinois program reduced 

VOC emissions in 2011 by 9.0 tons 

per day. Table 3.4 summarizes 

estimates for Metro-East St. Louis 

nonattainment area where VOC 

emissions were reduced by 1.0 ton per day in 2011.

3.3 Administrative Actions 

Waivers - In cases where vehicles cannot be brought into compliance after reasonable attempts 

are made to repair them, both the Vehicle 

Inspection Law of 1995 and 2005 provide for 

the issuance of waivers if certain criteria are 

met. Federal enhanced I/M requirements 

specify that waivers cannot be granted unless a 

minimum of $450 in emissions-related repairs 

are performed on the vehicle. Additional 

requirements also apply to ensure the vehicle 

emissions components have not been 

deliberately removed or tampered with, and 

that repairs have been performed by 

professional repair technicians. Table 3.5 

summarizes waiver issuance activity since 

implementation of the enhanced program. The 

number of waivers issued and the waiver rates 

for each year compare favorably with the 3% 

maximum rate mandated in the USEPA 

enhanced performance standard. 

Economic Hardship Compliances – 

In cases where vehicle owners cannot afford the cost 

of repairs, an Economic Hardship Compliance is 

available. Low-income owners can petition the 

Agency for a one-year extension of the test-by date. 

In order to qualify, the owners must meet specified 

income requirements and provide written estimates 

of the cost of repair. Table 3.6 summarizes the 

numbers of economic hardship compliances issued 

since 1999. 

Temporary Extensions – Prior to the 

implementation of the Vehicle Emissions Inspection 

Law of 2005, the Illinois program also provided 

motorists needing additional time to comply, with a 

four-month Temporary Extension. This extension 

was most often issued for vehicles that were inoperable, were awaiting repairs or parts, or were 

temporarily being used outside of the emissions test area. 

This option is no longer available to motorists whose vehicles are subject to the registration 

denial enforcement mechanism. Instead, the SOS has implemented a policy which allows the 

motorist to extend the vehicle’s registration expiration date by up to six months (up to four 

months starting in April 2012). SOS changes the motorist $6.50 for each month of extension. 

This policy was implemented in December of 2008.

4 CUSTOMER SERVICE 

4.1 Motorist Convenience/Wait times 

Since the inception of the emissions test program in 1986, the Agency has strived to provide 

vehicle owners with a high level of customer service and convenience in all aspects of the 

program. The network of inspection stations has been developed to provide for facilities 

reasonably close to work or home, and was sized to minimize the time required for vehicle 

testing. The Illinois EPA requires that the test contractor provide a station network that ensures 

that the average monthly wait time at any station does not exceed 15 minutes. 

While wait times vary significantly by station, month and day of week, on average, the wait 

times experienced during the last several years have been well below prescribed minimums. 

Table 4.1 lists network-wide annual average wait 

times for 1999 - 2011. 

The Illinois test system has been designed to 

continuously monitor the wait time at each 

station, providing motorists with current 

estimated wait time they would likely experience 

prior to testing. Actual wait times are measured 

for each vehicle tested and the current estimated 

wait computed for each station. Estimated wait 

times are displayed on a monument sign at the 

station entrance and are available on the Agency 

website (http://www.epa.state.il.us/air/vim/), 

The current wait time is also available through 

the toll-free wait time hotlines for all test 

stations. Motorists can access current wait times 

by dialing a toll-free telephone number for each test station, which are listed in the vehicle 

emission test notices. 

Finally, the Agency website (http://www.epa.state.il.us/air/vim/queue-cameras.html) provides a 

link to live cameras at each centralized test station, which shows the current queue length. 

4.2 Public Information/Motorist Assistance 

The Agency, SOS, and the test contractor have staff available during regular business hours to 

help vehicle owners with questions or problems encountered with the test program. The test 

contractor maintains a customer service office in each full service test facility (9 in Chicago and 

3 in Metro-East), staffed by trained customer service representatives to assist in explaining test 

requirements and procedures, and to perform gas cap retests and conduct waiver inspections. 

The Agency also maintains telephone hot lines with phone staff trained in all facets of program 

operation. They provide general information (i.e. facility locations, hours of operation, etc.),

provide directions to the test stations, and advise motorists of how to proceed if there are errors 

in registration or test data, or if they are unable to have the vehicle tested. The Agency also 

maintains a website (http://www.epa.state.il.us/air/vim/) containing information about the 

program. 

4.3 Enforcement/Notification 

Prior to 2008, Illinois utilized a “computer-matching” enforcement system. The Agency relied 

on registration data provided by the SOS to identify vehicles required to be tested in a given 

year. The Agency then randomly assigned the vehicle a test month throughout the year. The 

Vehicle Emissions Inspection Law of 1995 established a four-month test period in which the 

owner may have the vehicle tested prior to the Agency notifying the SOS to initiate enforcement 

action. Non-compliance resulted in the suspension of the vehicle owner’s driver’s license, the 

vehicle registration, or both. Prior to the first day of the assigned test month, the Agency mailed 

a test notice to the owner/lessee of the vehicle. 

As noted in Section 2.1, Illinois converted from the computer-matching enforcement system to a 

registration denial based enforcement system, beginning January 1, 2008. This change was 

mandated by the Vehicle Emissions Inspection Law of 2005 and requires any owner of a vehicle 

subject to emissions inspection to have the vehicle inspected and provide proof of compliance in 

order to obtain or renew a vehicle registration. 

Beginning in the last quarter of 2007, vehicles with January 2008 registration expiration dates or 

later received initial test notices stating that the vehicle’s registration renewal would be denied 

unless the vehicle had complied with the Vehicle Emissions Inspection Law of 2005. In addition, 

at the end of January 2008, any outstanding vehicle registration subject to suspension under the 

computer-matching enforcement mechanism was transferred into the registration denial system. 

This meant that registration renewal application for any vehicle in this category would be denied 

without demonstration of compliance with the Vehicle Inspection Law of 2005. Therefore, there 

were no driver’ license suspensions or registration suspensions for Calendar Year 2011. 

The summary of all 

initial test and notices 

for Calendar Year 2011 

is contained in Table 4.2.

4.4 Compliance Rates 

The Agency monitors vehicle compliance rates on a monthly basis. This is done to ensure that 

the Illinois I/M program is meeting federal requirements and design objectives necessary to 

achieve emission reductions committed to in the State Implementation Plan (SIP). The 

compliance rate is 

determined for each 

assigned month 

grouping1

 by 

comparing the 

number of vehicles 

in each group that 

have complied (i.e., 

passed the test or 

received a waiver) 

with the number of 

all active vehicles 

(i.e., passed, waived 

or still outstanding). 

Figure 4.2 contains 

compliance rates by 

“Reg Expiration” 

(i.e., vehicles that 

achieve compliance prior to the registration expiration (registration denial)), and “8 Months” 

(i.e., 8 months after vehicle was originally notified of the requirement to test). 

Starting May 1, 2008 under the new testing contract with Applus, preprinted VIRs are no longer 

used as was the previous case. The VIR barcode is generated by the test equipment at the time of 

the test and printed on the blank VIR sheet. 

4.5 Repair Industry Monitoring and Reporting/Outreach 

A critical component of enhanced I/M programs is the collection and evaluation of information 

on repairs made to failing vehicles. In order to qualify for a retest, motorists are required to 

provide information on the repairs that were performed. The information provided is then 

combined with retest results to assess the effectiveness of repairs being performed. On a 

quarterly basis, the test contractor publishes the Repair Shop Report Card that provides motorists 

with names and addresses of repair shops that have demonstrated a high level of competency in 

performing emissions repairs. Each shop is graded based upon whether the vehicle passes, fails 

or is rejected for readiness during the retest following repair. 

The letter grade for each shop is updated quarterly and is based on the success rate of the shop in 

fixing a vehicle. Shops that repair at least five vehicles with emissions failures during the past 

six months and achieve at least a 75 percent success rate are included in the report card. The 

letter grade is calculated by dividing the number of successful repairs by the total repairs

performed by the shop. The vehicle must pass the retest following the repair to be counted as a 

successful repair. Any vehicle that fails or is rejected for OBD readiness following a repair will 

not be counted as a successful repair. The repair shop grade will be based on the success rate 

(93-100% = A, 84-92% = B, 75 – 83% = C). 

All owners of vehicles failing the initial test receive the Report Card to help them make informed 

choices about where to have emissions-related repairs performed. The Report Card data is also 

available on the Illinois EPA website at www.epa.state.il.us/air/vim/reportcard.html. 

Additionally, a complete list of all repair shops performing emissions repairs, regardless of 

grade, is available for reference at each inspection facility. 

In a continuing effort to improve the quality of repairs being made to failing vehicles, the 

Agency has implemented a repair industry outreach program. Several times per year, the 

Agency conducts and sponsors Enhanced I/M training seminars for repair technicians on exhaust 

and OBD testing and repair. 

4.6 Vehicle Damage Claims Process 

The actual number of damage claims submitted is extremely small in comparison to the numbers 

of vehicles tested. Table 4.3 shows the 

annual number and rate of claims since 

enhanced testing began in 1999. In 2011, 

there were 85 claims filed, or 0.004% 

percent of all vehicles tested (4 claims per 

100,000 vehicles tested). As shown, the 

rate of claims has decreased significantly, 

in part due to the phase-in of less-intrusive 

OBD testing in 2002, and more recently, 

the elimination of the IM240 test. Most 

claims were related to minor damage (e.g., 

dents, scratches, scuffed tires) and were 

settled with test facility management 

providing a purchase order for repair on 

the spot. 

On rare occasions, damage claims cannot be handled at the test facility level and require thirdparty evaluation. These major claims are handled by a three-step process: 

1) The motorist files a claim at the station; 

2) The claim is thoroughly investigated, with some claims involving an independent 

third-party evaluation; and, 

3) Either payment is offered or the claim is denied. 

The independent third-party evaluation is handled by over 30 Claim Evaluation Centers (CECs), 

using ASE2

 certified technicians who are trained in testing and repair. These CECs render an

 ASE (Automotive Service Excellence) is a nationally recognized non-profit organization performing voluntary 

testing and certification of automotive technicians.

opinion on the likely cause of damage based on established facts and professional opinion. 

Owners not satisfied with the resolution of the claim may pursue the matter through the Better 

Business Bureau’s binding arbitration process or in circuit court. Owners may also petition the 

Agency to review the adequacy and completeness of the contractor’s proposed resolution to a 

claim. During the 2011 reporting period, only two claims were referred to CECs. 
21 

5 QUALITY ASSURANCE 

Contractor oversight is achieved utilizing the following quality assurance functions: 

5.1 Overt Audits 

Overt audits primarily consist of Testing Procedure Monitoring (TPM) performed by the State 

Inspectors, and equipment audits performed by the Quality Assurance Auditors. 

TPM – Testing Procedure Monitoring is an evaluation of individual vehicle tests performed by 

the lane attendant. The audit form was developed utilizing Part 276, Title 35 of the Illinois Code, 

the Enhanced I/M Request for Proposal (RFP), and station and lane operating manuals that are 

part of the contract documentation. The audits help ensure that proper testing procedure is 

consistently utilized at all the testing stations. During the 2011 reporting period, the State 

Inspectors performed 12 audits daily. Results were discussed with Station Management and 

entered in the TPM database. 

Equipment Audits – The IM97 gas audits are the primary equipment audits. The gas audits 

simulate an exhaust test with known concentrations of a tri-blend gas introduced into the 

analyzer system. The readings posted by the analyzer are compared to the known values of the 

audit gas. If any of the readings are outside of the tolerance range of the audit gas, the lane is 

closed to further vehicular testing until the analyzer is repaired and passes a State retest. During 

the 2011 period, every testing lane received at least one IM97 gas audits. Additional equipment 

audits address the pressure decay and/or leak flow gas cap testing systems. For a complete 

summary of the equipment audits conducted in 2011, refer to Appendix C and D. 

Starting in October 2009, the Quality Assurance Auditors began auditing the OBD analyzers 

with verification testers. The audit was modeled after the guidance provided in the document 

“U.S. EPA Steady State and Transient Testing Equipment Audit Guidance.” In addition, they 

expanded the scope of the audit and have tested most lanes using six different protocols. 

As a result of this new OBD analyzer audit, an OBD protocol issue was discovered in one of the 

test lanes at the Lincolnshire station. The OBD analyzer was unable to communicate with the 

CAN protocol. The test contractor replaced the analyzer cable which rectified the problem. 

Finally, the Quality Assurance Auditors also review the contractor’s Quality 

Control/Maintenance books on a routine basis. These books contain the records of required 

calibrations and all equipment maintenance performed by the contractor. Summaries of the 

reviews are maintained by QA. 

5.2 Covert Audits 

Covert audits were performed by state inspectors to verify whether contractor personnel (lane 

inspectors) followed established test procedures when performing a test. Two unique vehicles 

with regular license plates were used for these audits, including one vehicle with dual exhaust. 

These audits were used only to verify compliance with test procedures. No attempt was made to 

improperly influence (bribe) the lane inspectors because state policy prohibits the use of such 

funds (“buy money”) by agencies other than the Illinois State Police. The covert vehicles 
22 

generally pass the test, but the Agency occasionally attempts to make the vehicle fail by shutting 

down a fuel injector. However, modern engine management systems make it very difficult to get 

the vehicle to fail by this method for any length of time. The Agency has elected not to take more 

drastic measures to make vehicles fail, such as removing a catalyst. 

State Inspectors document covert audits by preparing a Covert Test Procedure Monitor after the 

conclusion of each covert audit. Results were shared with Agency field Supervisor(s), Field 

Services Manager, and the contractor Operations Manager. The contractor took appropriate 

disciplinary action in a timely manner when serious deficiencies were observed. For the 

complete summary of quality assurance reports and audit results, refer to Appendix B. 
23 

6 TEST PROGRAM ISSUES 

During the 2011 reporting period, the Agency focused on implementing the Amendments to the 

“Vehicle Emissions Inspection Law of 2005” (625 ILCS 5/13C). Specifically, in anticipation of 

the February 1, 2012 elimination of the steady-state idle mode exhaust evaporative system 

integrity tests and the exemption of pre-2007 model year heavy-duty vehicles with gross vehicle 

weight rating (GVWR) between 8,501 and 14,000 pounds and all heavy-duty vehicles with 

GVWR greater than 14,000 pounds, the Agency performed the following tasks: 

- Modified the test notice selection routine to ignore the newly exempt vehicle (starting 

with the November 2011 selection that includes vehicles with February 2012 registration 

expirations). 

- Modified the test lane software to: 

- Remove the idle/gas cap option for fallback testing; 

- Remove all idle/gas cap associated calibration requirements and lockouts; and, 

- Add the visual inspection test for vehicles where OBD testing is not possible due 

to the vehicle’s design. 

- Develop and implement a blanket clear mechanism to clean up all newly exempted 

vehicles. This blanket clear will be run on the evening of January 31, 2012, and will clear 

the emissions test flag on the SOS vehicle registration database and mark the records on 

the Agency VID as permanently exempt. 

These tasks were completed successfully in the allotted time and resulted in a trouble free 

implementation of the new OBD-only test program on February 1, 2012.
