Air Bag Control Module: Service Precautions
Restraints Control Module
WARNING: Installing a connected restraints control module (RCM) is dangerous. Movement generated during installation can cause the crash
sensor inside the unit to send an electrical signal to the air bag modules. This will deploy the air bag modules, which may result in serious
injury. Therefore, before connecting the RCM, firmly mount the unit to the vehicle.
Disconnecting the RCM connector or removing the RCM with the ignition switch ON can cause the air bag modules to deploy, which may seriously
injure you. Before disconnecting the RCM connector or removing the RCM, turn the ignition switch to LOCK, then disconnect the negative battery cable
and wait for more than 1 minute to allow the backup power supply of the RCM to deplete its stored power.
Always wear safety glasses when repairing an air bag system vehicle and when handling an air bag module.
After deployment the air bag surface can contain deposits of sodium hydroxide, a product of the gas generant combustion that is irritating to the skin.
Wash your hands with soap and water afterwards.
Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury.
Air bag modules with discolored or damaged trim covers must be replaced, not repainted.
Vehicle sensor orientation is critical for proper system operation. If a vehicle equipped with an air bag system is involved in a collision, inspect the
sensor mounting bracket and wiring pigtail for deformation. If damaged, install a new sensor whether or not the air bag is deployed.
NOTE: Repair is made by installing a new part only. If the new part does not correct the condition, install the original part and perform the diagnostic
procedure again.
