Seat Position Sensor: Service and Repair

Seat Position Sensor

NOTE: Driver seat shown, passenger similar.









1. Position the seat all the way up (if equipped) and to the middle of the seat track.

2. WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.

Turn the ignition OFF and wait at least one minute.

3. From under the rear of the affected seat, remove the retaining clip, disconnect the electrical connector and remove the seat position sensor.

4. To install, reverse the removal procedure.

5. Prove out the SRS as follows:

Turn the ignition switch from ON to OFF. Wait 10 seconds, then turn the ignition switch back to ON and visually monitor the air bag warning indicator with the air bag modules installed. The air bag warning indicator will illuminate continuously for approximately 6 seconds and then turn off. If an air bag SRS fault is present, the air bag warning indicator will:
- fail to light.
- remain lit continuously.
- flash at a 5 Hz rate (RCM not configured).

The air bag warning indicator may not illuminate until approximately 30 seconds after the ignition switch has been turned from the OFF to the ON position. This is the time required for the RCM to complete the testing of the SRS. If the air bag warning indicator is inoperative and a SRS fault exists, a chime sounds in a pattern of 5 sets of 5 beeps. If this occurs, diagnose and repair the air bag warning indicator and any SRS fault discovered.

Use a scan tool and clear all continuous DTCs from the RCM and Occupant Classification System Module (OCSM).
