Impact Sensor: Service and Repair

FRONT IMPACT SEVERITY SENSOR

Front 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.
- If a vehicle has been in a crash, inspect the restraints control module (RCM) and the impact sensor (if equipped) mounting areas for deformation. If damaged, restore the mounting areas to the original production configuration. A new RCM and sensors must be installed whether or not the air bags have deployed. Failure to follow these instructions may result in serious personal injury or death in a crash.
- Always tighten the fasteners of the restraints control module (RCM) and impact sensor (if equipped) to the specified torque. Failure to do so may result in incorrect restraint system operation, which increases the risk of personal injury or death in a crash.
- To reduce the risk of accidental deployment, do not use any memory saver devices. Failure to follow this instruction may result in serious personal injury or death.

NOTE:
- The air bag warning indicator 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.

All vehicles
1. Depower the SRS. See DEPOWERING AND REPOWERING.

Vehicles equipped with 2.3L and A/C
2. For the RH front impact severity sensor, remove the air cleaner and air cleaner outlet pipe.

All vehicles

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.

3. Remove the front impact severity sensor bolt

- Tightening Torque: 12 N.m {1.2 kgf.m, 9 ft.lbf)

4. Disconnect the front impact severity sensor electrical connector and remove the sensor.
5. To install, reverse the removal procedure.
6. Repower the SRS. See DEPOWERING AND REPOWERING.
