DRIVER AIR BAG MODULE







Removal and Installation

WARNING:
- Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an air bag module.This will reduce the risk of injury in the event of an accidental deployment.
- Carry a live air bag module with the air bag and trim cover pointed away from your body.This will reduce the risk of injury in the event of an accidental deployment.
- Do not set a live air bag module down with the trim cover face down.This will reduce the risk of injury in the event of an accidental deployment.
- 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.
- To reduce the risk of personal injury, do not use any memory saver devices.

CAUTION: Make sure each of the 3 driver air bag module wire clips are disengaged from each of the 3 steering wheel hooks before removing the driver air bag module from the steering wheel.Failure to do so will damage the driver air bag module and steering wheel.

NOTE:
- The air bag warning lamp illuminates when the restraints control module (RCM) fuse is removed and the ignition switch is ON.This is normal operation and does not indicate a SRS fault.
- The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
- Repair is made by installing a new part only.If the new part does not correct the condition, install the original part and carry out the diagnostic procedure again.
