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.

Install in reverse order of removal. Note 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 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.

  Note

If the Airbag Indicator Lamp -K75- indicates a fault, check the DTC memory, erase it and check it again → Vehicle diagnostic tester.

Seat Position Sensor, Removing and Installing, with Seat Occupied Sensor for Passenger Airbag Deactivation

The seat position sensor is a component of the wiring harness to the Passenger Occupant Detection System Control Module -J706-, whose electrical harness connectors must not be disconnected. To replace the seat position sensor, the electrical wires to the seat position sensor must be disconnected and the new seat position sensor must be connected with crimp connectors.

Removing

  WARNING

  • Follow all safety precautions when working with pyrotechnic components (refer to → Chapter "Pyrotechnic Components Safety Precautions") and passenger occupant detection system passenger airbag deactivation (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.

- Remove the front passenger seat. Refer to → Chapter "Front Seat, Removing and Installing".

- Attach the front seat to the Engine/Transmission Holder - Seat Repair Fixture -VAS6136-. Refer to → Chapter "Front Seat, Mounting on Fixture for Seat Repair".

- Remove screw -3- and seat position sensor -4- from the seat pan lower frame.

  Caution

Do not damage the insulation on the individual wires.

- Cut protective hose -2- to just in front of clip -1-.

- Cut through both electrical wires at the places marked with -arrow A- and -arrow B- to approximately 1/3 to 2/3 of the free length.

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.

- Cut the electrical wires on the new seat position sensor to the same length as those on the old sensor.

  • The same wire colors must have the same length.

- Connect the wires with crimp connectors -arrow A- and -arrow B-. Refer to → Electrical Equipment General Information; Rep. Gr.97; Wiring Harness and Connector Repairs.

- Wrap the entire length of the wiring harness from the clip to the seat position sensor with fabric-reinforced adhesive tape.

Install in reverse order of removal. Note the following:

- Install the seat position sensor -arrow C- on the lower seat frame. Refer to → Chapter "Seat Position Sensor, Removing and Installing, with Seat Occupied Sensor for Belt Fastening Detection".
