Front Impact Severity Sensor

FRONT IMPACT SEVERITY SENSOR







Removal and Installation

WARNING:
- Vehicle sensor orientation is critical for proper system 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.
- Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an air bag module. This will reduce the risk of injury in the event of an accidental deployment.
- To reduce the risk of personal injury, do not use any memory saver devices.

NOTE:
- The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault.
- The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
- Repair is made by installing a new part only. If the new part does not correct the condition, install the original part and carry out the diagnostic procedure again.

1. Depower the system.
2. Disconnect the front impact severity sensor electrical connector.
3. Remove the 2 sensor mounting bolts.
- To install, tighten to 12 Nm (9 lb-ft).







4. Remove the front impact severity sensor.
- To install, align the locator tab of the front impact severity sensor mounting bracket to the opening in the lower radiator support sheet metal.

5. WARNING: The tightening torque of the air bag front impact severity sensor retaining bolts is critical for correct system operation.

NOTE: Make sure the lower radiator support and front impact severity sensor bracket mating surfaces are clean and free of foreign material.

To install, reverse the removal procedure.

6. Repower the system.
