Passive Occupant Detection System

Passive Occupant Detection System

• Seat occupied recognition controls automatic passenger airbag deactivation.

• This equipment is only installed on vehicles released in the USA and Canada.

• Follow all of the general safety precautions for working on the airbag and the passenger occupant detection system; refer to => [ Passive Occupant Detection System Safety Precautions ] Service Precautions.

• Before handling pyrotechnical components (for example, disconnecting the connector), the person handling them must "discharge static electricity". For example, by briefly touching the door striker pin.

The passenger occupant detection system service kit is precalibrated and must not be disconnected. The service kit consists of:

• Seat Occupied Recognition Control Module (J706)

• Seat Occupied Recognition Pressure Sensor (G452)

• Passive Occupant Detection System Mat

• Seat cushion

Removing

- Move the seat height adjustment into the center before lifting the seat out.

- Remove the front passenger seat. Refer to => [ Front Seat ] Front Seat.

- Disconnect the battery ground cable with the ignition switched on.

• If the vehicle has a pass-through, it is sufficient to fold the backrest forward; it does not have to be removed.

- Remove the front backrest. Refer to => [ Backrest ] Backrest.

• Do not disconnect the connectors from the seat occupied recognition pressure sensor (G452) and seat occupied recognition control module (J706).

- Using a narrow screwdriver, carefully press the seat occupied recognition pressure sensor (G452) - 3 - off the bracket - arrow -.






- Open the seat occupied recognition pressure hose guide - 1 - and free up the pressure hose - 2 -.

- Release the retaining spring - 1 - and tilt the seat occupied recognition control module (J706) - item 2 - out of the mount.






- Remove the electrical connector - 4 - from the bracket by pressing the release and removing the electrical connector.

- Open the headlamp mounting tab on the electrical wiring harness guide - 5 - - arrow - and free up the wiring harness - 3 -.

- Remove the cover and front seat cushion cover. Refer to => [ Front Seat Cover and Cushion ] Front Seat Cover and Cushion.

- Carefully remove the seat occupied recognition mat clips - 1 - and - 3 - on the front of the seat pan using a pry lever (80 - 200).






- Remove the cover and the cushion for the seat pan by first removing the passenger occupant detection system pressure sensor (G452) through the opening in the seat pan.

Damage risk.

• Do not bend the seat occupied recognition pressure hose and mat.

- Remove the cover and cushion for the lower seat frame, the mat for the - 2 - passenger occupant detection system and the passenger occupant detection system pressure sensor (G452).

Installation

- Clean the threaded holes for self-locking screws, e.g. a thread tap.

- Replace all self-locking screws.

Installation is reverse of removal, but note the following:

• Follow all of the general safety precautions for working on the airbag and the passenger occupant detection system.

• Before handling pyrotechnical components (for example, connecting electrical connector), the person handling them must "discharge static electricity". For example, by briefly touching the door striker pin.

• Do not bend the seat occupied recognition pressure hose and mat.

• Make sure the electrical connectors are pushed in as far as the stop and that they engage audibly.

Connect the battery with the ignition switched on. Pyrotechnic components could deploy after connecting the battery if they were not repaired correctly. Individuals must not be inside the vehicle when connecting the battery.

- Connect the battery ground cable with the ignition turned on.

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 seat occupied recognition control module.

- Select "airbag" in "Guided Fault Finding" to complete.
