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 airbags 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.
