Front Impact Severity Sensor

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 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.
- 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. Remove the 2 bolts and the 2 pin-type retainers from the upper grille.

3. 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.

NOTE:
- Make sure the radiator support and front impact severity sensor and bracket assembly mating surfaces are clean and free of foreign material.
- Note position of the locator tab on the front impact severity sensor and bracket assembly for installation.

While gently positioning forward the upper grille, remove the bolt from the front impact severity sensor assembly.
- To install, tighten to 12 Nm (9 lb-ft).

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