Removal and Installation

WARNING:
- Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an airbag module. This will reduce the risk of injuring the event of an accidental deployment.
- To reduce the risk of personal injury, do not use any memory saver devices.

NOTE:
- If a seat equipped with a SRS component is being serviced, the SRS must be depowered.
- 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 indicates supplemental restraint system (SRS) fault.
- The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

All seats
1. Remove the front seat and depower the supplemental restraint system (SRS).
2. Remove the front seat backrest.

13. WARNING:
- If the air bag cover has separated or the air bag material has been exposed, install a new side air bag module. Do not attempt to repair the air bag module. Failure to do so may result in personal injury in the event of an air bag deployment.
- Inspect the mounting surfaces of the side air bag module for any foreign objects before installing the side air bag module. If any foreign objects are found, remove them. Failure to do so may result in personal injury, in the event of an air bag deployment.
