Removing
WARNING
- Follow all safety precautions when working with pyrotechnic components (refer to → Chapter "Pyrotechnic Components Safety Precautions") and on the passenger occupant detection system (refer to → Chapter "Passenger Occupant Detection System Deactivation Additional Safety Precautions, Market-Specific").
- Before handling pyrotechnic components (for example, disconnecting the connector), the person handling it must "discharge static electricity". This can be done by touching the door striker, for example.
- Disconnect the battery Ground (GND) cable with the ignition turned on. Refer to → Electrical Equipment; Rep. Gr.27; Battery; Battery, Disconnecting and Connecting.
- Remove the front passenger seat. Refer to → Chapter "Front Seat, Removing and Installing".
- Fasten the front seat on the Engine/Transmission Holder - Seat Repair Fixture -VAS6136-. Refer to → Chapter "Front Seat, Mounting on Fixture for Seat Repair".

Installing
WARNING
- Follow all Safety Precautions when working with pyrotechnic components. Refer to → Chapter "Pyrotechnic Components Safety Precautions".
- Before handling pyrotechnic components (for example, connecting the connector), the person handling it must "discharge static electricity". This can be done by touching the door striker, for example.
Installation is performed in reverse order of removal, while noting the following:
Note
Make sure the connectors are installed correctly and are secure.
WARNING
Ignition must be on when connecting battery. If pyrotechnic components (for example, airbag, belt tensioner) are not repaired correctly, they may deploy unintentionally after connecting battery. There must not be anyone inside the vehicle when connecting the battery.
DANGER!
When working on vehicles with the ignition already switched on or that are ready to drive there is a danger of the engine starting unexpectedly and of being poisoned by gas in enclosed areas. Risk of body parts and/or clothing being clamped or pulled.
Perform the following before switching on the ignition:
- Move the selector lever into P.
- Activate the parking brake
- Turn off the ignition.
- Open the hood
- Connect the charger, such as the Battery Charger -VAS5095A- to the jump start of the 12V vehicle electrical system.
- Turn on the ignition.
- Connect the battery GND cable with the ignition turned on. Refer to → Electrical Equipment; Rep. Gr.27; Battery; Battery, Disconnecting and Connecting.
When installing a new service kit and after each repair on the front passenger seat where the seat and/or the backrest cover is "disengaged", a basic setting procedure must be performed on the passenger occupant detection system control module. Refer to → Chapter "Passenger Occupant Detection System Deactivation Additional Safety Precautions, Market-Specific".
- Select "airbag" in "Guided Fault Finding" to complete. Refer to Vehicle Diagnostic Tester.
- -J706 passenger occupant detection system control module basic setting
Note
If the Airbag Indicator Lamp -K75- signals a fault after installing, check the Diagnostic Trouble Code (DTC) memory, erase it and check it again. Refer to Vehicle Diagnostic Tester.
