Disassembly
WARNING:
- Always carry or place a live air bag module with the air bag and deployment door/trim cover/tear seam pointed away from the body. Do not set a live air bag module down with the deployment door/trim cover/tear seam face down. Failure to follow these instructions may result in serious personal injury in the event of an accidental deployment.
- Never probe the electrical connectors on air bag, safety canopy 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.
- If the seat side air bag cover has been damaged or separated from its mounting, or if the air bag material has been exposed, install a new seat side air bag module. Never try to repair the seat side air bag module. Failure to follow these instructions may result in the seat side air bag deploying incorrectly, which increases the risk of serious personal injury or death in a crash.
- Front seat backrest trim covers installed on seats equipped with seat side air bags cannot be repaired. A new trim cover must be installed. Cleaning is permissible. Failure to follow these instructions may result in the seat side air bag module deploying incorrectly and increase the risk of serious personal injury or death in a crash.
- 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 restraints control module (RCM) fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault.
- If a side air bag deployment took place the seat backrest foam pad, trim cover, and side air bag module must be installed new. The backrest frame should be installed new if necessary.
- The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
- Driver side shown, passenger side similar.

9. WARNING:
- Before installing the seat side air bag module/deployment chute assembly:
- Inspect the side air bag module and mounting surfaces for any damage or foreign material.
- Remove any foreign material from the mounting surfaces of the deployment chute, the seat backrest frame mounting bracket and the air bag module cavity in the seat backrest foam pad.
- Install new parts if damaged.
Failure to follow these instructions may result in the seat side air bag deploying incorrectly, which increases the risk of serious personal injury or death in a crash.
- Inspect the seat side air bag module and mounting surfaces for any damage or foreign material before installing the seat side air bag module. If any damage is found, install new components. If any foreign material is found, remove it. Failure to follow these instructions may result in the seat side air bag module deploying incorrectly and increase the risk of serious personal injury or death in a crash.
- If the seat side air bag cover has been damaged or separated from its mounting, or if the air bag material has been exposed, install a new seat side air bag module. Never try to repair the seat side air bag module. Failure to follow these instructions may result in the seat side air bag deploying incorrectly, which increases the risk of serious personal injury or death in a crash.
- Check the seat side air bag deployment chute for damage. The deployment chute must not be repaired. If there is any damage to the deployment chute, a new seat back trim cover and deployment chute must be installed as a unit. Failure to follow these instructions may result in the seat side air bag module deploying incorrectly and increase the risk of serious personal injury or death in a crash.
- If the seat side air bag module deployment chute is not correctly positioned and closed, the seat side air bag module may not deploy correctly. Failure to follow these instructions may result in the seat side air bag module deploying incorrectly and increases the risk of serious personal injury or death in a crash.
NOTE: The alignment pin will only allow the side air bag module to be installed to the seat backrest mounting bracket one way.
Position the side air bag module into the deployment chute.
- Position the side air bag module into the deployment chute with the alignment pin offset to the top and the electrical connector to the bottom of the seat backrest. This will position the alignment pin correctly when the side air bag module and deployment chute are mounted to the backrest frame mounting bracket.
- The side air bag module mounting studs and alignment pin must come through the deployment chute stud openings.
10. WARNING:
- Before installing the seat side air bag module/deployment chute assembly:
