Front Impact Severity Sensor

FRONT IMPACT SEVERITY SENSOR







Removal and Installation

WARNING:
- 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.
- Vehicle sensor orientation is critical for correct system operation. If a vehicle equipped with an air bag SRS is involved in a collision, inspect the sensor mounting bracket and wiring pigtail for deformation. Replace and correctly position the sensor or any other damaged SRS components whether or not the air bag is deployed.
- To reduce the risk of personal injury, do not use any memory saver devices.

NOTE:
- The air bag warning lamp illuminates when the restraints control module (RCM) fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a 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.
- The vehicle requires 2 front impact severity sensors, 1 located on each side of the hood latch, on the radiator core support.

1. Depower the system.
2. Remove the 3 pin-type retainers and the radiator upper shield.

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

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

Remove the 2 front impact severity sensor bolts.
- To install, tighten to 12 Nm (9 lb-ft).

4. Disconnect the electrical connector and remove the front impact severity sensor.
5. To install, reverse the removal procedure.
6. Repower the system.
