Impact Sensor: Service and Repair

REMOVAL

WARNING:
- Vehicle sensor orientation is critical for proper operation. If a vehicle equipped with an air bag Supplemental Restraint System (SRS) is involved in a collision, inspect the sensor mounting bracket and wiring pigtail for deformation. Replace and properly position the sensor or any other damaged supplemental restraint system (SRS) components whether or not the air bag is deployed.
- To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing or replacing any front or side air bag supplemental restraint system (SRS) components and before servicing, replacing, adjusting or striking components near the front or side air bag sensors, such as doors, instrument panel, console, door latches, strikers, seats and hood latches.

The side air bag sensors are located at or near the base of the B-pillar.

To deplete the backup power supply energy, disconnect the battery ground cable and wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped).

NOTE: Repair is made by installing a new part only. If the new part does not correct the condition, install the original part and perform the diagnostic procedure again.

1. Disconnect the battery ground cable and wait at least one minute.
2. Remove the radiator upper sight shield.







3. Remove the air bag sensor.
1 Disconnect the air bag sensor electrical connector.
2 Remove the three screws.
3 Remove the air bag sensor.
