Side Air Bag: Service and Repair

SIDE AIR BAG MODULE







Removal

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 side air bag module with the air bag and tear seam pointed away from your body. This will reduce the risk of injury in the event of an accidental deployment.
- Do not set a live side air bag module down on the cover tear seam. 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.
- Side air bag modules with damaged covers must be replaced.
- Front seat back trim covers installed on seats equipped with side air bags cannot be repaired, they are to be replaced. Cleaning is permissible.
- To reduce the risk of personal injury, do not use any memory saver devices.

CAUTION: Use care when handling the seat and track assembly. Dropping the assembly or sitting on a seat not secured in the vehicle may result in damaged components.

NOTE:
- If a side air bag deployment took place, a new seat back pad, trim cover and side air bag module must be installed. The seat back frame should be replaced if necessary.
- When replacing the side air bag after deployment, refer to Seats for additional information concerning the installation of a new side air bag.
- 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.
