4.7 Programming and Coding
Since the introduction of OBDII and leading up to modern hybrids and EVs, hardware
and software technologies in cars have been advancing at an exponential rate. Updating
software may be the only way to fix the following issues:⚫

Drivability⚫

Fuel Efficiency⚫

Power Loss⚫

Fault Codes⚫

Durability of Mechanical Parts

The Programming and Coding function is used to re-flash the vehicle control modules,
which allows you to update the computer software of the vehicle to the latest version, as
well as to reprogram adaptive data of certain components after making repairs or
replacements.

50

NOTE
The programming function applies only when the vehicle is connected with a VCMI
device, which serves as a PassThru interface to establish communication with andtransfer data to the vehicle’s ECU.
Available programming or coding operations vary by test vehicle. Only the available
operations display in the tablet menu.
There are two general types of programming operations:A.

Coding — also known as Teach-in Program, or Component Adaptation, is used toreprogram adaptive data for vehicle control modules after repairs or replacementsof vehicle parts.

B.

Reprogramming — downloads the latest version of software from the online server
database through Internet access (this procedure is done automatically when thetablet is connected to the Internet, so there is no need to check for software updates
yourself), and reprograms the newest version into the vehicle's ECU.

NOTE
Ensure that the tablet is connected to a stable internet access before applying the ECU
programming function, so that the tablet is able to obtain access to the vehicle
manufacturer's server for update service.
Selecting the Programming opens a menu of operation options that vary by vehicle makeand model. Selecting a menu option either displays a programming screen or opens
another menu of additional choices. Follow the on-screen instructions to operate. How
and what information is presented on the screen vary by the type of operation being
performed.

4.7.1 Coding
The main section of the Coding screen displays a list of vehicle components and thecoding information that mainly consists of two parts:
1.

All available systems for coding are displayed on the left side, and the coding data
or value on the right side.

2.

The bottom of the main section displays the functional buttons that enable you tomanipulate the operation.

Check the vehicle condition and the coding information carefully. Use the functional
button to edit Codes for the corresponding components. Tap Send when you finish
editing all items. When the operation is completed, an execution status message suchas Completed, Finished or Successful, may display.

51

Tap the ESC button to exit the function.

4.7.2 Reprogramming
Before reprogramming begins:⚫

It is mandatory that the tablet is connected to a stable Wi-Fi network.

⚫

The tablet must be connected to the VCMI device via USB cable.

⚫

The tablet battery must be fully charged during module programming. Connect thetablet to a charger if needed.

⚫

Attach battery maintainer to vehicle battery to ensure a steady voltage is maintained
throughout programming. Voltage requirements differ by vehicle manufacturer.
Consult vehicle manufacturer recommendations prior to programming a module.

⚫

Do not quit the application during a module reprogramming as the process may failand may also result in permanent damage to the module.

Typical reprogramming operations require you to input and validate VIN number first. Tap
the input box and enter the correct number. The programming interface then displays.
The main section of the reprogramming interface offers information of the hardware, thecurrent software version and the newest software versions to be programmed into thecontrol units.
A series of on-screen operational instructions will display to guide you through theprogramming procedure.
Carefully read the on-screen information and follow the instruction to execute theprogramming procedure.

4.7.3 Re-flash Errors
IMPORATANT
When reprogramming onboard, always make sure the vehicle battery is fully charged
and in good working condition. During reprogramming, the operation may fail if voltage
falls below the proper operation voltage. Sometimes a failed operation can be recovered,
but the failed reprogramming can also ruin the control module. We recommend
connecting an external battery maintainer to the vehicle to ensure a steady voltage ismaintained throughout programming. The required voltage differs by vehicle
manufacturer. Consult vehicle manufacturer for correct voltage to be maintained.
Occasionally a flash update procedure may not complete properly. Common causes offlash errors include poor cable connections between the tablet, VCMI, and vehicle, thevehicle ignition being switched off before the flash procedure is complete, or low vehicle
52

battery voltage.
If the process quits, recheck all the cable connections to assure good communications
and initialize the flash procedure. The programming procedure will automatically repeat
if the previous operation does not succeed.

4.8 Generic OBDII Operations
The OBDII/EOBD vehicle diagnosis option offers a quick way to check for DTCs, isolate
the cause of an illuminated malfunction indicator lamp (MIL), check monitor status prior
to emissions certification testing, and perform other emissions-related services. The
OBDII direct access option is also used for testing OBDII/EOBD compliant vehicles thatare not included in the database. Diagnostics Toolbar Buttons at the top of the screen
are available for specific vehicle diagnostics. See Table 4-2 Diagnostics Toolbar Buttons
for details.

4.8.1 General Procedure➢

To access the OBDII/EOBD diagnostics functions

4.8.2 Function Descriptions
This section describes the various functions of each diagnostic option:

4.8.2.1

DTC & FFD

When this function is selected, the screen displays a list of Stored Codes and Pending
Codes. When the Freeze Frame data of certain DTCs are available for viewing, asnowflake button will display on the right side of the DTC item. The Erase Codes andRead codes functions can be applied by tapping the Function Buttons at the bottom of
the screen.
54⚫

Current Codes
Current codes are emission-related DTCs from the ECM of the vehicle. OBD
II/EOBD Codes have a priority according to their emission severity, with higherpriority codes overwriting lower-priority ones. The priority of the code determines theillumination of the Malfunction Indicator Lamp (MIL) and the codes erase procedure.
Manufacturers rank codes differently, so DTCs may vary by vehicle.

⚫

Pending Codes
These are codes whose storing conditions have been met during the last drive cycle,
but need to be met on two or more consecutive drive cycles before the DTC stored.
The purpose of displaying pending codes is to assist the service technician after avehicle repair when diagnostic information is cleared, by reporting test results after
a single driving cycle.

⚫

a)

If a test fails during the driving cycle, the DTC associated is reported. If thepending fault does not occur again within 40 to 80 warm-up cycles, the fault is
automatically cleared from memory.

b)

Test results reported do not necessarily indicate a faulty component or system.
If test results indicate another failure after additional driving, a DTC is stored toindicate a faulty component or system.

Freeze Frame
In most cases the stored frame is the last DTC reported. Certain DTCs, those thathave a greater impact on vehicle emission, have a higher priority. In these cases,
DTC of the highest priority is the one for which the freeze frame records are retained.
Freeze frame data includes a "snapshot" of critical parameter values at the time the
DTC is stored.

⚫

Erase Codes
This option is used to clear all emission-related diagnostic data including DTCs,
freeze frame data and specific manufacturer-enhanced data from the vehicle ECM.
This option resets the I/M Readiness Monitor Status for all vehicle monitors to Not
Ready or Not Complete status.
A confirmation screen displays when the clear codes option is selected to prevent
accidental loss of data. Select Yes on the confirmation screen to continue, or selectNo to exit.

4.8.2.2

I/M ReadinessThis function is used to check the readiness of the monitoring system. It is an excellent
function to use prior to having a vehicle inspected for state emissions compliance.
55Selecting I/M Readiness opens a submenu with two choices:⚫

Since DTCs Cleared — displays the status of monitors since the last time the DTCs
are erased.

⚫

This Driving Cycle — displays the status of monitors since the beginning of thecurrent drive cycle.

4.8.2.3

Live Data

This function enables the display of real-time PID data from the ECU. Displayed data
includes analog and digital input and output, and system status information broadcast in
the vehicle data stream.
Live data can be displayed in various modes, see Live Data for detailed information.

4.8.2.4

O2 Sensor Monitor

This function allows retrieval and review of recent O2 sensor monitor test results stored
on the vehicle's on-board computer.
The O2 Sensor Monitor test function is not supported by vehicles that communicate using
a controller area network (CAN). For O2 Sensor Monitor tests results of CAN-equipped
vehicles, refer to On-Board Monitor.

4.8.2.5

On-Board Monitor

This function allows you to view the results of On-Board Monitor tests. The tests areuseful after the service when a vehicle's control module memory is already erased.

4.8.2.6

Component Test

This function enables dual-directional control of the ECM so that the diagnostic tool cantransmit control commands to operate the vehicle systems. This function is useful indetermining how well the ECM responds to a command.

4.8.2.7

Vehicle Information

This function enables the display of the vehicle identification number (VIN), calibration
identification number, calibration verification number (CVN), and other information of thetest vehicle.

4.8.2.8

Vehicle Status

This function checks the current condition of the vehicle, such as the communication
protocols of OBDII modules, number of fault codes, and status of the Malfunction
Indicator Light (MIL).

The Service section is specially designed to provide quick access to the vehicle systems
for various scheduled service and maintenance tasks. The typical service operation
screen is a series of menu driven executive commands. Follow on-screen instructions to
select appropriate execution options, enter correct values or data, and perform
necessary actions. The application will display detailed instructions to complete selected
service operations.
After entering each special function, the screen will display two application choices:
Diagnosis and Hot Functions. The Diagnosis enables the reading and clearing of codes
which is sometimes necessary after completing certain special functions. Hot Functions
consists of sub functions of the selected special function.

Figure 5-1 Service Menu
Several most commonly used services are described in this chapter.

5.1 Oil Reset Service
Perform reset for the Engine Oil Life system, which calculates an optimal oil life changeinterval depending on the vehicle driving conditions and climate. The Oil Life Reminder
must be reset each time the oil is changed, so the system can calculate when the next
oil change is required.

63

NOTE
1. Always reset the engine oil life to 100% after every oil change.
2. All required work must be carried out before the service indicators are reset. Failure
to do so may result in incorrect service values and cause DTCs to be stored by therelevant control module.
3. For some vehicles, the scan tool can reset additional service lights such as
maintenance cycle and service interval. On BMW vehicles for example, service
resets include engine oil, spark plugs, front/rear brakes, coolant, particle filter, brakefluid, micro filter, vehicle inspection, exhaust emission inspection and vehicle checks.

5.2 Electric Parking Brake (EPB) Service
This function has a multitude of usages to maintain the electronic braking system safely
and effectively. The applications include deactivating and activating the brake control
system, assisting with brake fluid control, opening and closing brake pads, and setting
brakes after disc or pad replacement.

5.2.1 EPB Safety
It can be dangerous to perform Electric Parking Brake (EPB) system maintenance, so
before you begin the service work, please keep these rules in mind.
✓

Ensure that you are fully familiar with the braking system and its operation before
commencing any work.

✓

The EPB control system may be required to be deactivated before carrying out any
maintenance/diagnostic work on the brake system. This can be done from the tool
menu.

✓

Only perform maintenance work when the vehicle is stationary and on level ground.

✓

Ensure that the EPB control system is reactivated after the maintenance work has
been completed.

NOTE
Autel accepts no responsibility for any accident or injury arising from the maintenance of
the Electric Parking Brake system.

64

5.3 Tire Pressure Monitoring System (TPMS) Service
This function allows you to quickly look up the tire sensor IDs from the vehicle ECU, as
well as to perform TPMS replacement and reset procedures after tire sensors are
replaced.

5.4 Battery Management System (BMS) Service
The Battery Management System (BMS) allows the tool to evaluate the battery charge
state, monitor the close-circuit current, register the battery replacement, activate the rest
state of the vehicle, and charge the battery via the diagnostic socket.
NOTE
1. This function is not supported by all vehicles.
2. The sub functions and actual test screens of the BMS may vary by vehicle, please
follow the on-screen instructions to make correct option selection.
The vehicle may use either a sealed lead-acid battery or an Absorbed Glass Mat (AGM)
battery. Lead acid battery contains liquid sulphuric acid and can spill when overturned.
AGM battery (known as VRLA battery, valve regulated lead acid) also contains sulphuric
acid, but the acid is contained in glass mats between terminal plates.
It is recommended that the replacement aftermarket battery has the same specifications,such as capacity and type, as the exiting battery. If the original battery is replaced with adifferent type of battery (e.g. a lead-acid battery is replaced with an AGM battery) or abattery with a different capacity (mAh), the vehicle may require reprogramming of the
new battery type, in addition to, performing the battery reset. Consult the vehicle manual
for additional vehicle-specific information.

5.5 Diesel Particle Filter (DPF) Service
The Diesel Particle Filter (DPF) function manages DPF regeneration, DPF component
replacement teach-in and DPF teach-in after replacing the engine control unit.
The ECM monitors driving style and selects a suitable time to employ regeneration. Cars
driven a lot at idling speed and low load will attempt to regenerate earlier than cars driven
more with higher load and speed. For regeneration to take place, a prolonged highexhaust temperature must be obtained.
In the event of the car being driven in such a way that regeneration is not possible, i.e.,frequent short journeys, a diagnostic trouble code will eventually be registered in addition
to the DPF light and “Check Engine” indicators displaying. A service regeneration can berequested in the workshop using the diagnostic tool.
65

Before performing a forced DPF regeneration using the tool, check the following items:⚫

The fuel light is not on.

⚫

No DPF-relevant faults are stored in system.

⚫

The vehicle has the specified engine oil.

⚫

The oil for diesel is not contaminated.

IMPORTANT
Before diagnosing the problematic vehicle and attempting to perform an emergency
regeneration, it is important to obtain a full diagnostic log and read out relevant measured
value blocks.
NOTE
1. The DPF will not regenerate if the engine management light is on, or there is a faulty
EGR valve.
2. The ECU must be re-adapted when replacing the DPF and when topping up the fueladditive Eolys.
3. If the vehicle needs to be driven in order to perform a DPF service, a second person
is needed for the function. One person should drive the vehicle while the other person
observes the screen on the Tool. Do not attempt to drive and observe the scan tool at
the same time. This is dangerous and puts your life and the lives of other motors andpedestrians at risk.

5.6

Immobilizer (IMMO) Service

An immobilizer is an anti-theft mechanism that prevents an automobile's engine fromstarting unless the correct ignition key or other device is present. This device prevents
thieves from starting the car by a method known as hot wiring. Most new vehicles havean immobilizer as standard equipment. An important advantage of this system is that it
doesn't require the car owner to activate it; it operates automatically. An immobilizer isconsidered as providing much more effective anti-theft protection than an audible alarm
alone; many auto insurance companies offer lower rates for vehicles that are equippedwith an immobilizer.
As an anti-theft device, an immobilizer disables one of the systems needed to start a
car's engine, usually the fuel supply or the ignition. This is accomplished by radio
frequency identification between a transponder in the ignition key and a device called aradio frequency reader in the steering column. When the key is placed in the ignition, thetransponder sends a signal with a unique identification code to the reader, which relays
it to a receiver in the vehicle computer control module. If the code is correct, the computer
allows the fuel supply and ignition systems to operate and start the car. If the code isincorrect or absent, the computer disables the system, and the car will be unable to start66

until the correct key is placed in the ignition.
The IMMO service can disable a lost vehicle key and program the replacement key fob.
One or more replacement key fobs can be programmed.

5.7 Steering Angle Sensor (SAS) Service
SAS Calibration permanently stores the current steering wheel position as the straightahead position in the SAS EEPROM. Therefore, the front wheels and the steering wheel
must be set exactly to the straight-ahead position before calibration. In addition, the VIN
is also read from the instrument cluster and stored permanently in the SAS EEPROM.
On successful completion of calibration, the SAS fault memory is automatically cleared.
Calibration must always be carried out after the following operations:⚫

Steering wheel replacement⚫

SAS replacement⚫

Any maintenance that involves opening the connector hub from the SAS to thecolumn⚫

Any maintenance or repair work on the steering linkage, steering gear or otherrelated mechanism⚫

Wheel alignment or wheel track adjustment⚫

Accident repairs where damage to the SAS or assembly, or any part of the steeringsystem may have occurred.

NOTE
1. Autel accepts no responsibility for any accident or injury arising from servicing the
SAS system. When interpreting DTCs retrieved from the vehicle, always follow the
manufacturer's recommendation for repair.
2. All software screens shown in this manual are examples, and actual test screens mayvary by test vehicle. Pay attention to the menu titles and onscreen instructions tomake correct option selections.
3. Before starting procedure, make sure the vehicle has an ESC button. Look for button
on dash.

7.1.6 Troubleshooting
A. If the oscilloscope cannot communicate with the MaxiSys tablet:⚫

Ensure the VCMI device is properly connected to the MaxiSys tablet via BT, WiFi or with the supplied USB cable.

⚫

Restart the MaxiSys tablet and reconnect the VCMI device if communication
between the two continues to fail.

B. If unwanted signals are displayed or signals are distorted:⚫

Use only the supplied test leads or probes to connect with the input channels.

⚫

Check the test leads or probes for damage.

⚫

Ensure the polarity of the test leads connections are correct.

⚫

Ensure the signal and ground connections are clean and secure.

⚫

Ensure the ground lead is providing a direct ground from the circuit to the input
channel.

⚫

Isolate the test leads from other components, leads, or systems that may induct
unwanted noise into the signal being tested including the electric motors,
secondary ignition components, relays, alternators.

135

7.1.7 Glossary
AC/DC Control
Each channel can be set to either AC coupling or DC coupling. With DC coupling, thevoltage displayed onscreen is equal to the true voltage of the signal with respect toground. With AC coupling, any DC component of the signal is filtered out, leaving only
the variations in the signal for the AC component.
Aliasing
When the signal frequency gets higher than half the scope's maximum sampling rate andexceeds the limit, a distorted waveform displays. This distortion is called aliasing.
Amplitude
The maximum voltage generated from the zero volts line of the oscilloscope.
Analog Bandwidth
The frequency at which a displayed sine wave has half the power of the input sine wave
(about 71% of the amplitude).
Buffer Size/Cache Size
The size of the oscilloscope's buffer memory. The buffer memory is used by theoscilloscope to temporarily store data. This helps to compensate for the differences indata transfer rate from one device to another.
Frequency
The number of signal occurrences per second. Frequency is measured in Hz (hertz).
Peak to peak voltage
The difference in voltage between the minimum and maximum voltages occurring in the
waveform.
Time Base
The time interval across the scope display.
Voltage Range
The range between the maximum and minimum voltages that can be accurately capturedby the oscilloscope.

136

Sampling Rate
The number of samples per second captured by the oscilloscope. The faster the sampling
rate of the scope, the more frequently it measures the signal voltage, and so the moredetailed will be the trace that appears on the scope screen.

Waveform Zooming
The zooming function allows you to change the size and position of a signal
during or after capturing a waveform to examine. It does not change the stored
data, only the way it displays.
The X-axis and Y-axis can be zoomed using your fingertips. The waveform canbe zoomed during or after capturing the signal.

201



Measurement Rulers
In the coordinate grid, there are two types of measurement rulers, which allow
the amplitude and time duration of a waveform to be measured precisely. They
are useful when determining signal characteristics such as amplitude at specificpoints, the cycle time (duration) and frequency.
The vertical Time Ruler — tap the Ruler Activator in the bottom left corner ofthe grid and drag it across the screen to the desired position. A Time Ruler isgenerated.
The horizontal Signal Ruler — the Signal Ruler can be generated in the similar
way by clicking the Ruler Activator in the top right corner and dragging it
downwards.
When dragging the Measurement Rulers, a Ruler Table showing time andvoltage values for the corresponding channels will be displayed. The Delta icon
refers to the absolute difference between the values of the rulers, which can belocked by tapping the Lock icon. Tap the X button in the upper right corner ofthe ruler table to delete all rulers.

7.3.6 Glossary
Vehicle Bus
A vehicle bus is a specialized internal communications network that interconnects
components inside a vehicle (e.g., automobile, bus, train, industrial or agricultural vehicle,
ship, or aircraft). Protocols include Controller Area Network (CAN), Local Interconnect
Network (LIN) and others.
CAN Bus
A Controller Area Network (CAN bus) is a robust vehicle bus standard designed to allow
microcontrollers and devices to communicate with each other in applications without ahost computer.
SAE International
Initially established as the Society of Automotive Engineers, is a U.S.-based, globally
active professional association and standards developing organization for engineering
professionals in various industries. Principal emphasis is placed on transport industries
such as automotive, aerospace, and commercial vehicles.
SAE J1708
SAE J1708 is a standard used for serial communications between ECUs on a heavy duty
vehicle and also between a computer and the vehicle. With respect to Open System
Interconnection model (OSI), J1708 defines the physical layer. Common higher layer
protocols that operate on top of J1708 are SAE J1587 and SAE J1922. The protocol ismaintained by SAE International.
SAE J1939
Society of Automotive Engineers standard SAE J1939 is the vehicle bus recommended
practice used for communication and diagnostics among vehicle components. It is usedin the commercial vehicle area for communication throughout the vehicle, with the213physical layer defined in ISO 11898.
J1850
Defines a serial data protocol. There are two variants- 10.4 Kbit/s (single wire, VPW) and41.6 Kbit/s (two wire, PWM). Mainly used by US manufacturers, also known as PCI(Chrysler, 10.4 Kbit/s), Class 2 (GM, 10.4 Kbit/s), and SCP (Ford, 41.6 Kbit/s).
OBD
On-board diagnostics (OBD) is an automotive term referring to a vehicle's self-diagnostic
and reporting capability. OBD systems give the vehicle owner or repair technician accessto the status of the various vehicle engine systems.
OBD-II diagnostic connector
The OBD-II DLC (post-1996 vehicles) is usually located under the instrument panel on
the driver side, though there are several exceptions. The SAE J1962 specification
provides for two standardized hardware interfaces, called type A and type B. Both arefemale, 9-pin (2x8), D-shaped connectors, and both have a groove between the two rowsof pins.
DLC
The data link connector (DLC) is the multi-pin diagnostic connection port for automobiles,
trucks, and motorcycles used to interface a scan tool with the control modules of a given
vehicle and access on-board diagnostics and live data streams.

21 Compliance Information
FCC Compliance

FCC ID: WQ8MAXISYSULTRAThis equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. Thisequipment generates uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in aparticular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, theuser is encouraged to try to correct the interference by one or more of the following
measures:⚫

Reorient or relocate the receiving antenna.

⚫

Increase the separation between the equipment and receiver.

⚫

Consult the dealer or an experienced radio/TV technician for help.

This device complies with part 15 of the FCC Rules. Operation is subject to the following
two conditions:(1) This device may not cause harmful interference, and(2) This device must accept any interference received, including interference that may
cause undesired operation.
Changes or modifications not expressly approved by the party responsible forcompliance could void the user's authority to operate the equipment.
SAR
The radiated output power of this device is below the FCC radio frequency exposure
limits. Nevertheless, the device should be used in such a manner that the potential forhuman contact is minimized during normal operation.
The exposure standard for wireless devices employs a unit of measurement known as
the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6 W/Kg. Tests
for SAR are conducted using standard operating positions accepted by the FCC with thedevice transmitting at its highest certified power level in all tested frequency bands.
268

Although the SAR is determined at the highest certified power level, the actual SAR levelof the device while operating can be well below the maximum value. This is because thedevice is designed to operate at multiple power levels so as to use only the power
required to reach the network. To avoid the possibility of exceeding the FCC radio
frequency exposure limits, human proximity to antenna should be minimized.
