Seat Position Sensor With Seat Occupied Sensor For Passenger Airbag Deactivation
Seat Position Sensor 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 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
• Follow all safety precautions when working with pyrotechnic components, refer to => [ Restraint System Components ] Description and Operation and passenger occupant detection system passenger airbag deactivation. Refer to => [ Passive Occupant Detection Sensor, Additional Safety Precautions ] Passive Occupant Detection Sensor, Additional Safety 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.
- Remove the front seat:
• Standard seat and Sport seat (manual), refer to => [ Manual Standard Front Seat ] Manual Standard Front Seat.
• Standard seat and sport seat (power), refer to => [ Power Standard Front Seat ] Power Standard Front Seat.
- Attach the front seat to the fixture for seat repair (VAS 6136). Refer to => [ Installing the Front Seat on VAS 6136 ] Installing the Front Seat On VAS 6136.
- Remove the bolt - 3 - and the seat position sensor - 4 - from the seat pan lower frame.
Do not damage the insulation on the individual wires.
- Cut the protective hose - 2 - back just in front of the 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
• Follow all safety precautions when working on pyrotechnic components. Refer to => [ Restraint System Components ] Description and Operation.
• 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.
- 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 electrical wires with crimp connectors - arrow A - and - arrow B -.
- Wrap the entire length of the wiring harness from the clip to the seat position sensor with fabric-reinforced adhesive tape.
- Install the seat position sensor, making sure the hook - arrow C - on the sensor is inserted in the seat pan lower frame.
Further installation is performed in reverse sequence of removal, but observe the following:
• Make sure the connectors are installed all the way in and are secure.
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 (GND) cable with the ignition turned on.
• If the airbag indicator lamp (K75) indicates a fault after installation, the Diagnostic Trouble Code (DTC) memory must be checked, deleted and checked again.
