Seat Position Sensor G553/G554, with Seat Occupied Sensor for Passenger Airbag Deactivation
Seat Position Sensor G553/G554, with Seat Occupied Sensor for Passenger Airbag Deactivation
Driver seat position sensor (G553) / front passenger seat position sensor (G554)
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
• Follow all safety precautions when working with pyrotechnic components. Refer to and passenger occupant detection system passenger airbag deactivation. Refer to => [ Passenger Occupant Detection System Deactivation Additional Safety Precautions ] Passenger Occupant Detection System Deactivation Additional Safety Precautions.
• Before handling pyrotechnic components (for example, disconnecting the electrical connector), the person handling it must "discharge static electricity". This can be done by touching the door striker, for example.
- Remove the front seat. Refer to => [ Standard Seat ] Standard Seat.
- Attach the front seat to the fixture for seat repair (VAS 6136). Refer to => [ Installing Front Seat on Fixture for Seat Repair VAS 6136 ] Installing Front Seat on Fixture for Seat Repair VAS 6136.
- Remove screw - 3 - and 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
- 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.
Installation is performed in reverse order of removal, noting the following:
• Follow all safety precautions when working on pyrotechnic components. Refer to => [ Restraint System Components, Safety Precautions and Testing Procedures ] Description and Operation.
• Before handling pyrotechnic components (for example, connecting the electrical connector), the person handling it must "discharge static electricity". This can be done by touching the door striker, for example.
• Observe all measures when installing the front seat. Refer to => [ Standard Seat ] Standard Seat.
Installation note: For example tightening specifications, replace components. Refer to => [ Seat Position Sensor ] Description and Operation.
