Impact Sensor: Service and Repair

FRONT IMPACT SEVERITY SENSOR







Removal and Installation

WARNING: 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.

NOTE:
- The supplemental restraint system (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.
- 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 SRS fault.
- 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 SRS.

2. WARNING: 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.

CAUTION: If the hood latch support bracket is damaged in any way that would affect the way the front impact severity sensor mounts to its original manufactured position, a new hood latch support bracket must be installed.

NOTE: The front impact severity sensor is mounted to the hood latch support bracket.

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

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

Remove the front impact severity sensor and disconnect the electrical connector.
- When installing the front impact severity sensor, align the locators on the front impact severity sensor to the holes of the hood latch bracket.

4. To install, reverse the removal procedure.
5. Repower the SRS.
