Airbag system, On Board Diagnostic (OBD)

Functional description

The Airbag Control Module -J234- is located behind the console on the tunnel. It is equipped with DTC memory. The On Board Diagnostic (OBD) Data Link Connector (DLC) is located under the dash on the drivers side.

The control module detects Diagnostic Trouble Codes (DTC) in the airbag system and stores them in a permanent memory.

DTCs which can be attributed to a temporary open circuit in the wiring or a loose terminal will also be stored. These DTCs will be displayed as sporadic DTCs "SP."

After the ignition is switched on, the Airbag Malfunction Indicator Lamp (MIL) -K75- comes on for about 4 seconds and then goes out again, if the lamp then flashes for a further 15 seconds this signals that the front passenger airbag, is disabled.

If the Airbag Malfunction Indicator Lamp (MIL) -K75- does not go out again after about 4 seconds, then the voltage supply to the Airbag Control Module -J234- is inoperative. Check DTC memory Page 01-10 .

A DTC is present if the Airbag Malfunction Indicator Lamp (MIL) -K75- lights up again. Check DTC memory Page 01-10 .

If the Airbag Malfunction Indicator Lamp (MIL) -K75- flashes continuously then the Airbag Control Module -J234- must be replaced.

Comfort system 07.97, On Board Diagnostic (OBD)

Function

The new generation of central locking operates on the electric motor principle as compared to the previous pneumatic operation.

The locking units located in the doors (door lock) have an electric motor.

The motor locks the door and also takes care of the "Safe" condition, i.e. after locking at an external lock (door lock, tailgate, radio remote control) the vehicle is protected against theft and can no longer be unlocked from the interior. The feedback on the respective condition in the control module occurs via the contact switch in the locking unit.

All the known convenience functions can be performed with the electric comfort system, Front Interior Lights control, ATA with interior monitoring (being prepared), electric windows, mirror and the radio remote control.

If the Airbag Control Module is triggered, a signal is sent to the convenience control module to unlock the doors.

The Central control module for comfort system -J393- is located under the carpet in front of driver's seat. It is equipped with DTC memory. The Data Link Connector (DLC) for On Board Diagnostics is located under the dash on the drivers side.

Page 1 / 23Comfort system [micro] 07.97, On Board Diagnostic (OBD)


01-54

The control module recognizes DTCs and malfunctions in the central locking comfort system (comfort system includes central locking, anti-theft alarm, electric windows, radio frequency remote control, mirror) and stores them in non-volatile memory.

To commence trouble shooting, initiate On Board Diagnostic and retrieve the stored information with the V.A.G 1551 Scan Tool.

System tester V.A.G 1552 may also be used.

The function "Guided Troubleshooting" of the VAS 5051 should be used in diagnostic capable systems. Using this system will check the fuses via wiring and connections to the circuit.

The malfunction information displayed is used to refer to a DTC table with notes on the possible causes for directed repair measures.

Malfunctions which can be attributed to a temporary open circuit in the wiring or a loose terminal will also be stored. These malfunctions will be displayed as sporadic DTCs "SP."


01-55

Only statistical DTCs are considered:

Central locking inoperative

Mirror positioning motor inoperative

Electric window positioning motor inoperative

If the contents of the display are as shown then the coding is successful.

If the code number entered is not accepted by the control module, the previous coding will appear in the display:




In this case the control module has not been programmed with the relevant data for the vehicle. A check must then be completed to see if the correct control module for the vehicle has been installed (compare Part No. and letter index), or whether an incorrect code number has been entered.

If the control module cannot be coded (correct control module, correct code number), the control module is inoperative.

Furthermore, at this point the door control module is called-up and checked.

Notes:

The DTC table is listed according to the 5 digit code on the left.

Explanation of the DTCs (e.g. "open circuit/short circuit to Ground"):


Before replacing components indicated as being inoperative, check the wiring and connectors to these components as well as the Ground connections using wiring diagram. This is particularly relevant if DTCs are output as "occurring sporadically" (SP).

The DTCs displayed can be localized using the test table.

The DTC "01330 Convenience central control module; no communication" can appear "sporadically." This has no influence on the function of the comfort system and is therefore of no consequence. Erase DTC memory.

The malfunction "No communication" can also appear with the door control modules. This has no influence on the function of the comfort system and is therefore of no consequence. Erase DTC memory.

Comfort system 08.97 10.00,On Board

Diagnostic (OBD) Function

The new generation of central locking operates on the electric motor principle as compared to the previous pneumatic operation.

The locking units located in the doors (door lock) have an electric motor.

The motor locks the door and also takes care of the "Safe" condition, i.e. after locking at an external lock (door lock, tailgate, radio remote control) the vehicle is protected against theft and can no longer be unlocked from the interior. The feedback on the respective condition in control module occurs via the contact switch in the locking unit.

All the known convenience functions can be performed with the electric comfort system, Front Interior Lights control, ATA with interior monitoring (see description of system on Page 01-160 ), electric windows, mirror and the radio remote control.

If the Airbag Control Module is triggered, a signal is sent to the convenience control module to unlock the doors.

Page 1 / 25Comfort system 08.97 [micro]10.00,On Board Diagnostic (OBD)


01-157

The Central control module for comfort system -J393- is located under the carpet in front of driver's seat. It is equipped with DTC memory. The Data Link Connector (DLC) for On Board Diagnostics is located under the dash on the drivers side.

The control module recognizes malfunctions in the central locking comfort system (comfort system includes central locking, anti-theft alarm, electric windows, radio frequency remote control, mirror) and stores them in a non-volatile memory.

To commence trouble shooting, initiate On Board Diagnostic and retrieve the stored information with the V.A.G 1551 Scan Tool.

System tester V.A.G 1552 may also be used.

All the functions that were previously possible with the V.A.G 1551/1552 can be performed with the new tester VAS 5051 in operating mode "Vehicle On Board Diagnostic (OBD)":

Operating instructions for vehicle diagnosis, testing and Information system VAS 5051.

The malfunction information displayed is used to refer to a DTC table with notes on the possible causes for directed repair measures.

Malfunctions which can be attributed to a temporary open circuit in the wiring or a loose terminal, will also be stored. These malfunctions will be displayed as sporadic DTCs "SP."


01-158

Only statistical malfunctions are considered:

Central locking inoperative

Mirror positioning motor inoperative

Electric window positioning motor inoperative

Anti-theft alarm system, determining possible sources for activation

The breakdown of the display content illustrated on Page 01-261 for display group number 15 gives information as to which component triggered the alarm system last, and can therefore help troubleshooting and repair.

This "DTC memory" cannot be erased.

Interior monitoring system, description

The interior monitoring system is an integral part of the anti-theft alarm system. The systems consists of two sensors into which the reading lights are integrated. Setting the operating mode of the reading lights is performed on each of the sensors separately.

The interior sensors work on the ultrasonic wave principle. The alarm of the anti-theft alarm system will be triggered if movement is detected in the interior when the system is active.

The interior sensors can be switched off via a switch in the B-pillar/door sill and via the adaptation (function 10, channel number 05). To do this the ignition key must be withdrawn from the ignition switch, then operate switch and lock the vehicle.

The sensors will be switched on again the next time the vehicle is unlocked.

A waiting time of at least 30 seconds must be observed before commencing tests when the vehicle is locked.


01-161

System active indicator

The optical central locking system active indicator is via an additional LED in the upper part of the driver's door inner trim. The LED flashes for a period of time and then goes out.

When the LED is activated it will differentiate between the following functions:

Central locking using SAFE system (lock once) LED activation then 50ms on and 950ms off, when the safe condition is obtained

Central locking not using SAFE system (lock twice) LED goes out.

The anti-theft alarm system (ATA) is not always displayed.

Adaptation: matching ignition keys to radio frequency remote control

Notes:

If new or additional ignition keys are required they must be matched to the immobilizer and comfort system control electronics.

The matching procedure must always be carried out for all the ignition keys, including the existing ones.

The number of keys already matched will be displayed when the adaptation (matching) function is selected.

With the introduction of this generation of comfort system it is possible to program additional functions. The functions and the programming are described from Page 01-271 .

The matching can be interrupted with the -C- button of the V.A.G 1551.

WARNING!

The V.A.G 1551 dealership number (Dealership code) will be stored in immobilizer control module when matching ignition keys.

Driver's side seat adjustment, On Board Diagnostic (OBD)

Seat adjustment, function

The 8-way seat is equipped with a seat and mirror memory function.

With this system individual seat and mirror adjustments can be stored in the memory. Each of the memory buttons (-1-, -2-, and -3-) can be used to store the individual settings for one person.

The seat and mirrors will move automatically into the required position by pressing the appropriate button when there is a change of driver.

In the driver's seat adjustment, the position of the exterior mirrors (left and right) when driving forward and the position of the right exterior mirror for reversing can be stored and recalled for each memory button (-1-, -2-, and -3-)

The adjustments stored on a memory button can also be called up using the button for the radio frequency remote control.

The memory system can be turned off at any time using the red switch -4- (MEM OFF). The seat and the exterior mirrors can then only be set manually with switches -5- and -6-.

Page 1 / 22Driver's side seat adjustment, On Board Diagnostic (OBD)

01-297

On Board Diagnostic (OBD), function

It is an independent system and has the On Board Diagnostic (OBD) address word 36 "Seat adjustment driver's side."

The seat adjustment control module -J136- is located under the driver's seat and is connected to the comfort system via the CAN-bus.

It is equipped with DTC memory. The Data Link Connector (DLC) for the On Board Diagnostic (OBD) is located under the dash on the drivers side. The control module detects malfunctions in the system and stores them in a permanent memory.

To commence trouble shooting, initiate On Board Diagnostic and retrieve the stored information with the V.A.G 1551 Scan Tool. System tester V.A.G 1552 may also be used.

The malfunction information displayed is used to refer to a DTC table with notes on the possible causes for directed repair measures. Malfunctions which can be attributed to a temporary open circuit in the wiring or a loose terminal will also be stored. These malfunctions will be displayed as sporadic DTCs "SP."

The individual operating functions are described in the following description.


01-298

Memory system, initializing

Notes:

All data stored for the seat and mirror settings will be lost when the vehicle battery is disconnected.

This data will be retained in future control modules even after the battery has been disconnected.

Each new setting stored on the same button will erase the previous data.

It is not possible to store settings on the memory buttons if the red switch is switched-off (switch protrudes).

The battery voltage must not be below 10.5 V. Otherwise the system detects low voltage and will store a malfunction in the DTC memory.

The following test steps must be performed for the initialization:

- Open driver's door.


- Then move the seat backrest forward as far as stop.

This position will be recorded for reference when the stop limit switch-off occurs.


01-299

Seat and mirror settings for normal driving, storing


- Set the seat.

- Set both exterior mirrors.

The settings are now stored on the selected memory button.

The stored settings can be recalled via the memory buttons (1-3) as well as via the radio frequency remote control.

Allocating a seat adjustment to a radio frequency remote control keyis described at the end.

Notes:

- Now press one of the memory buttons (1-3) and hold it depressed for about 3 seconds until an acoustic signal confirms that the settings are stored in the memory.

When the vehicle battery is disconnected all the data stored for the seat and mirror settings are lost.

For future versions of the control module this data will be retained even when the battery is disconnected.

Each time settings are stored on a button the previous data will be erased.


01-300

Mirror setting with transmission selin reverse position, storing

This function cannot be performed until the seat/mirror settings have been stored Pa01-299

- Switch the ignition on.

- Set mirror adjustment switch to right mirro

- Engage reverse gear. The mirror will movthe factory setting or into a previously stoposition.

- Set the mirror to the desired position.

The settings are now stored on the selectedmemory button.

The stored settings can be recalled via the buttons (1-3) as well as via the radio frequeremote control.

Allocating a seat adjustment to a radio frequremote control keyis described at the end.

- Now press one of the memory buttons (1hold it depressed for about 3 seconds unacoustic signal confirms that the settings stored in the memory.


01-301

Notes:

When the vehicle battery is disconnected all the data stored for the seat and mirror settings are lost.


Each time settings are stored on a button the previous data will be erased.

As soon as reverse gear is engaged the right exterior mirror moves into the currently stored position or into the previous set position. This procedure will be interrupted if the mirror is manually adjusted to a new position.

As soon as the reverse gear is disengaged the right exterior mirror will move back to the position stored for normal driving.

Every time the seat and mirror adjustment for normal driving is changed, the individual setting for the right exterior mirror for reversing must also be reset, otherwise the previously set position is active.


01-302

Allocating radio frequency remote control key to memory buttons

After storing the seat and mirror settings ( Page 01-299 ) there is a 10 second period where the radio frequency remote control key can be allocated to the appropriate memory button.

The number of the radio frequency remote control key will be transferred from the comfort system central control module via the CAN-bus to the memory control module.

- Pull the radio frequency remote control key out of the ignition lock.

- Press the open button of the radio frequency remote control key and hold it depressed for at least 1 second until an acoustic signal confirms the allocation.

The settings are stored under the selected memory button.


01-303

Notes:

If the remote control key was previously allocated to a different memory button, the old allocation will be erased.

If the radio frequency remote control key is allocated to a memory button to which another button is already allocated, the old allocation will also in this case be erased.

The allocation of a radio frequency remote control key to a memory button will be retained even when new seat and mirror settings are stored on this button.

When the vehicle battery is disconnected all allocations for radio frequency remote control keys to the memory buttons will be erased.



01-304

Seat and mirror settings for normal driving, activating

The settings stored can be activated via the memory buttons as well as by the radio frequency remote control.

Activating via the memory buttons

For safety reasons the seat and mirror settings can only be activated with the ignition switched off.

There are two possibilities for activating the stored settings:

One touch automatic memory:

- With driver's door open briefly press the desired memory button. The seat and exterior mirrors move automatically to the stored positions.

Push and hold memory:

- With the driver's door opened or closed press the desired memory button until the seat and exterior mirrors have moved into the stored positions.


01-305

Activating via the radio frequency remote control

For safety reasons the seat and mirror settings can only be activated with the ignition switched off.

- Briefly press the opening button of the radio frequency remote control and then open the driver's door. The seat and exterior mirrors move automatically into the stored position.


01-306

Mirror setting with selector in reverse position, activating

- Set mirror change-over switch to the right exterior mirror.

- Engage reverse gear. The right exterior mirror moves automatically into the stored position.

Note:

As soon as the reverse gear is disengaged the right exterior mirror moves back to the position stored for normal driving.
