Front Impact Severity Sensor

Special Tool(s):

REMOVAL AND INSTALLATION

Removal

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.

WARNING: Always were safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an air bag module. This will reudce the risk of injury in the event of an accidental deployment.

WARNING: 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.

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.

NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
