Depowering Procedure
WARNING: Always wear eye protection when servicing a vehicle. Failure to follow this instruction may result in serious personal injury.
WARNING: Never probe the electrical connectors on air bag, Safety Canopy(R) or side air curtain modules. Failure to follow this instruction
may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
WARNING: Remove restraint system diagnostic tools from the vehicle prior to road testing. If tools are not removed, the supplemental
restraint system (SRS) device may not deploy in a crash. Failure to follow this instruction may result in serious personal injury or death in a
crash and possibly violate vehicle safety standards.
WARNING: To reduce the risk of accidental deployment, do not use any memory saver devices. Failure to follow this instruction may result in
serious personal injury or death.
NOTE: The air bag warning indicator illuminates when the correct Restraints Control Module (RCM) fuse is removed and the ignition switch is ON.
NOTE: The Supplemental Restraint System (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.
1. Turn all vehicle accessories OFF.
2. Turn the ignition switch to OFF.
