Front Impact Severity Sensor

Front Impact Severity Sensor

NOTE: LH shown, RH similar.











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: Always make sure the correct Supplemental Restraint System (SRS) component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the Master Parts Catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.

NOTE: The air bag warning indicator illuminates when the correct Restraints Control Module (RCM) fuse is removed and the ignition is ON.

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

1. Depower the SRS. For additional information, refer to Supplemental Restraint System (SRS) Depowering and Repowering Supplemental Restraint System (SRS) Depowering and Repowering.

2. Remove the front impact severity sensor.
- For LH, remove the Air Cleaner (ACL). For additional information, refer to Fuel Delivery and Air Induction.

- For RH and 3.5L engine, proceed to Step 3.

- For RH and 3.5L Gasoline Turbocharged Direct Injection (GTDI) engine, remove the Charge Air Cooler (CAC) outlet hose. For additional information, refer to Fuel Delivery and Air Induction.

3. Disconnect the front impact severity sensor electrical connector.

4. 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 front impact severity sensor and mating surfaces are clean and free of foreign material.
Remove the bolt and front impact severity sensor.
- To install, tighten to 12 Nm (106 lb-in).

5. To install, reverse the removal procedure.

6. Repower the SRS. For additional information, refer to Supplemental Restraint System (SRS) Depowering and Repowering Supplemental Restraint System (SRS) Depowering and Repowering.
