Impact Sensor: Service and Repair
FRONT IMPACT SEVERITY SENSORFront Impact Severity Sensor:
Removal
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 restraint system operation. If a vehicle equipped with an 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 supplemental restraint system (SRS) fault.
- The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
- A 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. Depower the SRS. See DEPOWERING AND REPOWERING.
WARNING: The tighten torque of the air bag front impact severity sensor retaining nuts is critical for correct system operation.
NOTE:
- Make sure the radiator support and front impact severity sensor mating surfaces are clean and debris free.
- Note position of locator tab on sensor bracket for installation.
2. Remove the front impact severity sensor bolt
Tightening Torque: 12 N.m (1.2 kgf.m, 9 ft.lbf)
3. Disconnect the front impact severity sensor electrical connector and remove the sensor.
4. To install, reverse the removal procedure.
5. Repower the SRS. See DEPOWERING AND REPOWERING.
