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 correct Supplemental Restraint System (SRS) 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 See: Air Bag(s)
Arming and Disarming/Service and Repair/Supplemental Restraint System (SRS) Depowering and Repowering in the General Procedures portion.
2. Remove the rear door scuff plate.
3. Detach the rear door weatherstrip.
