Caution
Do not disconnect the electrical connectors on the Passenger Occupant Detection System Pressure Sensor -G452- and the Seat Occupied Recognition Control Module -J706-.
- Using a narrow screwdriver, carefully press the Passenger Occupant Detection System Pressure Sensor -G452--item 3- off the bracket -arrow-.
- Open the seat occupied recognition pressure hose guide -1- and free up the pressure hose -2-.
- Remove the screw -2- and remove the Passenger Occupant Detection System Control Module -J706--item 1- from the retainer.
- Disconnect the safety belt latch connector from the bracket by pressing the release and removing the electrical connector.
- Free up electrical wiring harness.
- Remove the bolt -1-.
- Unclip and remove the Front Passenger Seat Position Sensor -G554--item 2-.
- Remove cover and cushion (seat pan without a seat depth adjuster) from the seat pan and carefully fold it to the side. Refer to → Chapter "Seat Pan Cover and Upholstery, Removing and Installing, Standard, Comfort Seat".
- Carefully pry out the seat occupied recognition mat clips -1- and -3- on the front of the seat pan using a Pry Lever -80 - 200-.
- Remove the seat pan cover with upholstery by first guiding the Passenger Occupant Detection System Pressure Sensor -G452- with the wiring harness through the opening in the seat pan. Guide the Passenger Occupant Detection System Control Module -J706- through the opening last.
WARNING
Damage risk.
Do not bend the seat occupied recognition pressure hose and mat.
- Remove the seat pan cover with upholstery with the seat occupied recognition mat -2-, the Passenger Occupant Detection System Pressure Sensor -G452- and the Passenger Occupant Detection System Control Module -J706-.
- Separate the cover from the seat pan upholstery. Refer to → Chapter "Lower Seat Frame Cover and Cushion, Separating, Standard, Comfort, Folding Seat".
Caution
Do not separate the seat pan cushion from the seat occupied recognition mat.
Installing
Caution

Install in reverse order of removal. Note the following:
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, connecting the connector), the person handling it must "discharge static electricity". This can be done by touching the door striker, for example.
- Do not bend the seat occupied recognition pressure hose and mat.
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 Battery Charger -VAS5095A- to the battery jump start terminal.
- Turn on the ignition.
- Connect the battery ground 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 to the front passenger seat during which the seat and/or the backrest cover is "disengaged", a basic setting procedure must be performed for the passenger occupant detection system control module. Refer to → Chapter "Passenger Occupant Detection System Deactivation Additional Safety Precautions, Market-Specific".
- At the end, select the "Airbag" function in "guided fault finding" using Vehicle Diagnostic Tester.
