Appendix D- Test Procedures 
OBDII Test Procedures 

On-Board Diagnostics (OBD) is the monitoring and fault detection/notification process of the 

Powertrain Control Module (PCM) related to the vehicle's emission control system and 

powertrain operation on 1996 and newer model year vehicles. When an emissions control 

malfunction is detected, a dashboard light illuminates, displaying one of the following: "Check 

Engine," "Service Engine Soon," or the international engine symbol. If the OBD system detects 

a problem that may cause vehicle emission to exceed applicable federal standards, the 

Malfunction Indicator Light (MIL) is illuminated and the appropriate diagnostic trouble code 

(DTC) and engine operating conditions will be stored in PCM memory. 

1.0 Locate the Diagnostic Link Connector (DLC) on the vehicle being tested. 

Connect the vehicle to the test equipment. 

1.1 If the DLC is missing, has been tampered with, or is otherwise inoperable, 

the vehicle fails the test and shall be repaired. 

1.2 If the DLC is unaccessible, the problem must be remedied before the test 

can continue. 

2.0 Tum the ignition switch to the off position for at least 30 seconds. 

3.0 Visually examine the instrument panel to determine if the malfunction indicator 

light (MIL) illuminates, at least briefly, when the ignition key is turned to the 

"key on, engine off' (KOEO) position. Enter your visual inspection result into 

the test equipment. 

3 .1 If the MIL does not illuminate, the vehicle fails the test and must be 

repaired. 

4.0 Tum the ignition switch to the off position for at least 30 seconds. 

5.0 Start the engine so the vehicle is in the "key on, engine running" (KOER) 

condition and follow the test equipment screen prompts until the test is complete. 

6.0 For 1996-2000 model year vehicles two (2) not ready flags are allowed for a 

passing test. For 2001 and newer vehicles one (1) not ready flag is allowed. If 

the not ready status exceeds these numbers the vehicle must be driven additional 

miles until readiness monitors are set "ready" or repairs have been made allowing 

readiness flags to set ready. 

7.0 If the MIL is commanded on while the engine is running, regardless of Diagnostic 

Trouble Codes (DTC's), the vehicle will fail the test and will require repairs. 
8.0 Certain vehicles have been determined by the EPA to be OBDII deficient. The 

test equipment software will maintain a list of these vehicles and perform a 

modified OBDII test. 

9.0 A Certificate of Compliance will be issued if the vehicle meets the requirements 

established in this section. 
Two-Speed Idle (TSI) Test Procedures 

During a two-speed idle test, the Analyzer measures the tailpipe exhaust emissions of a vehicle 

while the vehicle idles at both high and low speed. The Analyzer tests vehicles for carbon 

dioxide in addition to hydrocarbons and carbon monoxide. The two-speed idle test comprises 

two phases: (1) high speed test (2200-2800 RPMs) for the first phase of the emissions test; then, 

(2) tested at idle (350-1100 RPMs). 

1.0 The Certified Emissions Inspector shall not inspect or test any motor vehicle with 

a mechanical condition which may cause injury to inspection personnel or 

damage to the inspection station or test equipment or which may affect the 

validity of the test, until such condition is corrected. Such conditions include, but 

are not limited to: coolant, oil, or fuel leaks; low oil or low fluid levels; and high 

visible emissions. 

2.0 Prepare the Analyzer for testing as specified by the manufacturer. 

3.0 Each vehicle shall be checked to determine that it is at normal operating 

temperature by feeling the top radiator hose or by checking the temperature 

gauge. Each vehicle shall be at normal operating temperature before performing 

the emissions inspection. 

4.0 The inspection shall be performed with the transmission in "park" or "neutral" 

and with all accessories off and the emergency brake applied. 

5.0 The Analyzer probe shall be inserted into the exhaust pipe at least twelve inches 

or as recommended by the Analyzer manufacturer, whichever is greater. 

6.0 If a baffle or screen prevents probe insertion of at least twelve inches, a suitable 

probe adapter or snug fitting, non-reactive hose which effectively lengthens the 

exhaust pipe shall be used. 

7.0 For all vehicles equipped with a multiple exhaust system that does not originate 

from a common point, both sides shall be tested simultaneously with an approved 

adapter. 

8.0 When inspecting a vehicle under windy conditions, the tailpipe shall be shielded 

from the wind with a suitable cover. 

9.0 With the tachometer properly attached, the vehicle shall be tested by following 

the screen prompts, answering questions, and entering required data. Vehicles 

failing because of excessive exhaust dilution shall repair the dilution problem 

prior to continuing the emission test. The dilution standard shall be contained in 

the Analyzer specifications provided by the approved vendor. 
10.0 The Certified Emissions Inspector shall verify the presence of a gas cap and enter 

the information into the Analyzer. 

11.0 Certain vehicles cannot be tested in the high speed (2200-2800 RPM) mode. The 

test equipment software will maintain a list of these vehicles and perform a 

modified test. 

12.0 A Certificate of Compliance shall be issued if the vehicle emissions levels are the 

same as or less than the applicable cutpoint standards as referenced in Appendix 

B, and the vehicle has a gas cap present. 
Diesel Powered Vehicles Test Procedures 

1.0 All diesel powered vehicles 2007 and newer shall be tested in accordance with the 

following procedure: 

1.1 Locate the Diagnostic Link Connector (DLC) on the vehicle being tested. 

Connect the vehicle to the test equipment. 

1.1.1 If the DLC is missing, has been tampered with, or is otherwise 

inoperable, the vehicle fails the test and shall be repaired: 

1.1.2 Ifthe DLC is unaccessible, the problem must be remedied before 

the test can continue. 

1.2 Turn the ignition switch to the off position for at least 30 seconds. 

1.3 Visually examine the instrument panel to determine if the malfunction 

indicator light (MIL) illuminates, at least briefly, when the ignition key is 

turned to the "key on, engine off' (KOEO) position. Enter your visual 

inspection result into the test equipment. 

1.3 .1 If the MIL does not illuminate, the vehicle fails the test and must 

be repaired. 

1.4 Turn the ignition switch to the off position for at least 30 seconds. 

1.5 Start the engine ·so the vehicle is in the "key on, engine running" (KOER) 

condition and follow the test equipment screen prompts until the test is 

complete. 

L6 If the vehicle has 1 or more monitors "not ready", follow the attached 

flowchart to determine whether the readiness check will be marked as pass 

or fail.

can be changed by authorized personnel should a security problem be identified. A software 

controlled solenoid lock may also be used on the secured drive door of the Testing Equipment. 

The solenoid lock may be used instead of or in addition to any key or combination lock that may 

be provided. The Testing Equipment software must control the solenoid lock and unlatch the 

doors in response to authorized requests from the audit menu while maintaining the 

appropriate levels of security. 

A tamper file must be created that includes the date, time, type, and location of the tamper 

lockout, date and time the lockout was cleared, and who cleared the lockout. The tamper 

lockout type and location must be accessible only through the lockout function of the Testing 

Equipment's audit menu. 

Access to the compact disc drive (CD}, if applicable, must be avai lable to 1/M Program Station 

personnel at all times. However, access to the BIOS, 1/M related programs, and data must be 

secured separate from the CD and additional drives. The Contractor shall provide a security 

method approved by the Department for the CD drive(s) to prevent unauthorized reads, writes, 

and executable. However, the Contractor may offer Testing Equipment with additional disk 

drives that can run optional software application programs. 

The Testing Equipment must prevent Contractor-authorized repair technicians from performing 

the following, except in a manner approved by the Department:

2.9 Exhaust Gas Analysis Equipment Specifications 

This section defines the requirements for the components needed to determine the 

concentrations of the exhaust gases during the TSI inspections. 

2.9.1 Measured Gases 

The Analyzer must measure hydrocarbons (HC) as hexane in parts per million (ppm), 

carbon monoxide (CO), carbon dioxide (C02), and oxygen (02) in percent. The Analyzer 

must have a digital display for vehicle engine speed and exhaust concentrations of HC, 

CO, C02, and 0 2 and must be capable of measuring exhaust concentrations of HC, CO, 

C02, and 0 2 at a minimum sample rate of twice per second. 

2.9.2 Warm-up Conditions 

The Analyzer must reach stability within 30 minutes from startup at 35 degrees 

Fahrenheit rF). The Analyzer must be considered warmed-up when the internal 

verifications are complete and the zero and span readings for HC, CO, C02, and 0 2 have 

stabilized within the allowable accuracy values for five minutes without adjustment. If 

stabilization has not been reached within an allotted time frame, then the Analyzer 

must prevent TSI inspection sequences and display a message instructing the Certified 

Emissions Inspector to call for service. Functional operation of the gas sampling system 

must remain disabled through an internal lockout until the instrument meets stability 

and warm-up requirements. 

2.9.3 Sampling System Components 

A) General: 

The sampling system must extract exhaust gas from a subject vehicle, remove 

particulate matter and aerosols from the sampled gas, drain the condensed water from 

the sample if necessary, and deliver the resultant gas sample to the Analyzer's sensors 

for analysis. The sampling system must, at a minimum, consist of a tailpipe probe, 

flexible sample line, continuously draining water removal system, particulate trap, 

sample pump, and flow control components. Provisions must be made for the 

introduction of zero air and calibration gases. Materials that are in contact with the 

gases sampled must not contaminate or change the composition of the gases to be 

12 

• 
analyzed, including gases from vehicles not fueled by gasoline. The system must be 

designed to be corrosion-resistant and to withstand vehicle exhaust. 

B) Sample Probe and Hose Criteria: 

Sample hose must be 25 feet in length with a tolerance of +I- 0.5 feet when measured 

from the front ofthe Analyzer cabinet. The hose must be composed of non-kinking 

material that will not be affected by or react to the exhaust gases. 

Sample hose and probe provided with each Analyzer must withstand exhaust gas 

temperatures at the probe tip of up to 1,100°F for 10 minutes. Use of dissimilar metals 

with thermal expansion factors of more than 5 percent must not be used in either the 

construction of probes or connectors. 

A positive means of retention must be incorporated to prevent the probe from slipping 

out of the tailpipe when in use. 

A thermally insulated securely attached hand grip must be provided on the probe to 

ensure easy probe insertion using one hand. 

The probe must be designed so that the tip extends 16 inches into the tailpipe and at 

least 10 inches into the vehicle's exhaust. 

The probe tip must be shielded to avoid inadvertent debris collection and sealed to 

prevent any sample dilution when it is inserted into the tailpipe. Use of a tailpipe 

extension is permitted as long as the extension does not change the exhaust back 

pressure by more than+/- 1 inch of water pressure. 

A straight probe tip must be provided that is bent less than 15 degrees, made of 

stainless steel solid-wall tubing with a 3/16 inch outside diameter, and designed so the 

connector between the removable probe t ip and the rigid portion of tubing is up inside 

the tailpipe at least three inches to reduce the effects of any leak that might occur. 

A probe tip cap suitable for performing a leak check must be provided ifthe vacuum 

decay method for performing a leak check is used. Otherwise, all hoses and connectors 

that are necessary to perform a leak check must be provided. 

The sample system must include equipment necessary to inspect vehicles equipped with 

dual exhaust pipes. The flow in each leg of the dual exhaust probe sample system must 

be equal. 

C) Particulate Filter and Water Trap: 

• The particulate filter must be capable of trapping 97 percent of all particulates and 

aerosols five microns or larger; 

• The filter must not absorb or adsorb HC; 

13 
• The filter housing must be transparent to allow the operator to observe the filter's 

condition without removing the housing. The filter must be removable and reliably 

seal after replacement; 

• The water trap must be sized to remove exhaust sample water from vehicles fueled 

with, or a combination of gasoline, propane, compressed natural gas (CNG), 

oxygenated fuels, and alternative fuels. The filter bowl, filter, and housing must not 

react to these fuels or the vehicle's exhaust gases. The condensed water must be 

continuously and sufficiently drained from the water trap's bowl to prevent 

condensation in the sample system or in the optical bench' s sample cell; and 

• Incorporate a back-purge system. 

D) Low Flow Indicator: 

The Analyzer must lockout official TSI inspections when the sample flow is below the 

acceptable level. The Analyzer's sample system must be equipped with a flow meter or 

equivalent device that detects sample flow degradation. The Analyzer must display a 

low flow condition message when flow rate causes the measurement error for any gas 

to exceed 3 percent of the gas value used for calibration or audit or causes the analyzer 

response time to exceed 13 seconds to 90 percent of a step change in input, whichever 

is less. The sample vacuum may be continuously monitored to detect a low flow 

condition as an alternative. 

E) Analyzer lockout: 

The Analyzer must lockout official TSI inspections when the sample flow is below the 

acceptable level. The Analyzer's sample system must be equipped with a flow meter or 

equivalent device that must indicate when sample flow degradation for any gas other 

than NO causes: 

• The measurement error to exceed 3 percent of the gas value used for checking; or 

• The Analyzer response time to exceed 13 seconds for a 90 percent step change in 

input. 

The sample vacuum may be continuously monitored to detect a low flow condition as 

an alternative. 

3.0 Analyzer Requirements 

3.1 Gas Calibration 

A) General: 

The Analyzer must automatically require and successfully pass a leak check and a gas calibration 

for HC, CO, C02, and 0 2 by a method that is approved by the Department. The Analyzer must not 

allow an error of more than 2 percent of the readings using the high and low range span gases 

14 

. ,. . 
for TSI inspections. The Analyzer must automatically prohibit the performance of the tailpipe 

portion of the vehicle emissions inspection when readings exceed the 2 percent error tolerance. 

The Analyzer channels must be adjusted to the center of the allowable tolerance range as a 

result of the gas calibration procedure. 

The standard gases to be used to calibrate and audit the Analyzer must meet the requirements 

in the Federal Clean Air Act, §207(b) and described in Subpart W of Part 85 of Chapter I, Title 40 

of the CFR. All standard gases purchased by the 1/M Program Station for use in the Analyzer 

must conform to the requirements established by the BAR for emissions inspection analyzer 

calibration gases and the National Institute of Standards and Technology (NIST). 

B) Gas Calibration Procedure: 

• The Analyzer must maintain accuracy between gas calibrations taking into account all errors, 

including noise, repeatability, drift, linearity, temperature, and barometric pressure; 

• The Analyzer must automatically require a zero gas calibration and a high and low range gas 

calibration for HC, CO, C02, and 0 2, where applicable. The Analyzer must record the gas 

reading data prior to the adjustment and other data pertinent to control charting Analyzer 

performance; 

• The gas calibration must be accomplished by the following method: Calibration gases that 

meet the requirements of Section 3.1: Calibration Gases for TSI Analyzers must be 

introduced into the calibration port of the Analyzer. The pressure in the sample cell must be 

the same with the calibration gas flowing as with the sample flowing during an inspection. 

Once the pressure is the same, the Analyzer must perform a zero gas calibration and a leak 

check. The leak check must ensure that the entire sample system does not leak. 

3.2 Calibration Gases for TSI Analyzers 

The following gases must be used for the two-point calibration and audit. 

A) Low Range Calibration Gas 

HC = 200 ppm propane 

CO = 0.5 percent 

C02 = 6.0 percent 

02 = Shop Air 

N2 = Balance 99.99 percent pure 

15 
B) High Range Calibration Gas 

HC = 3200 ppm propane 

CO = 8.0 percent 

C02 = 12.0 percent 

N2 = Balance 99.99 percent pure 

3.3 Dilution 

The flow rate of the Analyzer must not cause more than 10 percent dilution during sampling of 

vehicle exhaust gases from a 1.6 liter engine at normal idle. Ten percent dilution is defined as a 

sample of 90 percent exhaust and 10 percent ambient air. 

3.4 Calibration Prompts and Gas Usage 

The Analyzer must display prompts to guide the inspector through the gas calibration procedure 

in a manner that minimizes the amount of gas used. The Analyzer must be designed to keep the 

loss of calibration gas to less than 0.5 liter in 24 hours when the valve on the calibration gas 

bottle is left open. 

3.5 Propane Equivalency Factor 

The value of the PEF must range from 0.490 to 0.540 and be displayed in a manner acceptable 

to the Department for each gas audit and gas calibration point. If an optical bench must be 

replaced in the field, then the Contractor-authorized repair technician must change any external 

labels to correspond to the PEF of the new bench. The Analyzer must incorporate an algorithm 

relating PEF to HC concentration. Corrections to the PEF must be made automatically and the 

corrected PEF value must range from 0.470 to 0.560.
