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.
- 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.
All vehicles
1. WARNING: To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing or replacing any front or side air bag supplemental restraint system (SRS) components and before servicing, replacing, adjusting or striking components near the front or side air bag sensors, such as doors, instrument panel, console, door latches, strikers, seats and hood latches.
The side impact sensors are located at or near the base of the B-pillar.
To deplete the backup power supply energy, disconnect the battery ground cable and wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped).
Disconnect the battery ground cable and wait at least one minute.
2. WARNING: To reduce the risk of serious personal injury, read and follow all warnings, cautions, notes, and instructions in the supplemental restraint system (SRS) deactivation/reactivation procedure.
Deactivate the supplemental restraint system (SRS).
3. WARNING: To reduce the risk of serious personal injury, read and follow all warnings, cautions, notes, and instructions in the seat removal and installation procedure.
CAUTION: Use care when handling the seat and track assembly. Dropping the assembly or sitting on a seat not secured in the vehicle can result in damaged components.

6. Release the four seat back trim cover J-clips (three shown).
7. NOTE: If installing a new side air bag module. Use new retaining nuts. If the same side air bag module is to be reused then reuse the side air bag module nuts.
Remove the side air bag module nuts.
8. Position the side air bag module and deployment chute away from the mounting bracket and seat back frame.
9. Position the seat back trim cover and seat back pad forward enough to access the side air bag module.
10. Remove the side air bag module from the deployment chute.
- Pull the side air bag module mounting studs back through the deployment chute openings and remove the side air bag module from the deployment chute.
11. Disconnect and remove the side air bag module.
12. Detach the side air bag module wiring harness electrical connector at the rear of the cushion frame.

INSTALLATION
All vehicles
WARNING: To reduce the risk of serious personal injury, read and follow all warnings, cautions, notes and instructions in the supplemental restraint system deactivation/reactivation procedure.
1. Route the wiring harness as noted during the removal procedure.
2. Attach the side air bag module wire harness electrical connector at the rear of the seat cushion frame.
3. Connect the side air bag module electrical connector.
4. WARNING:
- Inspect the mounting surfaces of the side air bag module for ally 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.
- Inspect the side air bag deployment chute and the side air bag cavity in the seat back pad for any foreign objects. 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.
- Before installing the side air bag module into the deployment chute, check it for damage and foreign objects. If the air bag module is damaged, replace it. 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.
- 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.
- Check the side air bag deployment chute for damage. The deployment chute must not be repaired. If there is any damage to the deployment chute, the seat back trim cover and deployment chute must be installed new as a unit.
- If the air bag deployment chute is not correctly positioned, the side air bag may not deploy correctly.
NOTE: The alignment pin will only allow the side air bag module to be installed to the seat back 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 back. This will position the alignment pin correctly when the side air bag module and deployment chute are mounted to the seat back frame mounting bracket.
- The side air bag module mounting studs and alignment pin must come through the deployment chute stud openings.
5. WARNING: Inspect the mounting surfaces of the deployment chute and the seat back frame mounting bracket for any foreign objects, before installing the side air bag module/deployment chute assembly. 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.
Install the side air bag module onto the front seat back frame mounting bracket. Install the nuts.
- The deployment chute should not have any wrinkles or folds where it contacts the seat back frame mounting bracket.
6. Reposition the seat back pad and trim cover to the seat back frame.
7. Fasten the four seat back trim cover J-clips (three shown).
8. CAUTION: Inspect the seat back trim panel retaining hooks for damage. If damaged, install a new seat back trim panel.
Install the seat back trim panel.
1 Angle the top of the seat back trim panel inward and down to engage the retaining hooks to the seat back frame.
2 Install the two screws (not shown).
