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.
- Front seat backrest 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.
- Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury.
- Seat side air bag modules with damaged covers must be replaced.
NOTE:
- If a seat equipped with a supplemental restraint system (SRS) component is being serviced, the SRS must be depowered.
- The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault.
- The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
- If a seat side air bag deployment took place a new seat backrest pad, trim cover and side air bag module must be installed. Install a new seat backrest frame if necessary.
- 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.
- When servicing just the seat side air bag module, refer to Air Bag Systems for the side air bag module removal and installation procedure.
- Low-back seat shown, hi-back seat similar.

Seats with seat side air bags
2. WARNING:
- Inspect the side air bag deployment chute and the side air bag cavity in the seat backrest 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.
- Check the side air bag deployment chute and clips for damage. The deployment chute and clips must not be repaired. If there is any damage to the deployment chute or clips, the seat backrest trim cover and deployment chute must be installed new as a unit.
- 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 backrest trim cover and deployment chute must be installed new as a unit.
- If the air bag deployment chute is not properly positioned, the side air bag may not deploy properly.
- Inspect the mounting surfaces of the deployment chute and the seat backrest 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.
- Front seat backrest trim covers installed on seats equipped with side air bags cannot be repaired, they are to be replaced (cleaning is permissible).
Position the deployment chute and clips through the backrest foam pad.
3. WARNING: If the air bag deployment chute is not properly positioned and completely closed, the side air bag may not deploy properly.
Position the air bag deployment chute.
1 Insert the outboard side of the air bag deployment chute between the seat backrest pad and the side air bag module pulling it around the outboard side of the seat backrest frame.
2 Insert the inboard side of the air bag deployment chute between the seat backrest pad and the side air bag module from the inboard side of the seat backrest.
4. WARNING: If the air bag deployment chute is not properly positioned and completely closed, the side air bag may not deploy properly.
Attach the deployment chute clips and hook and loop strips.
- The side air bag deployment chute must encircle the side air bag module, going completely around the side air bag module and the side of the seat backrest frame.
- Align the side air bag deployment chute to the side air bag module, making sure it covers the length of the side air bag module, it must not cover the top or the bottom of the side air bag module.

Passenger seat
15. CAUTION:
- There are 3 occupant classification sensor (OCS) system service kits available for this vehicle (base seat, heated seat and climate controlled seat). Always make sure the correct OCS service kit is installed.
- It is necessary to rezero the OCS system when a front passenger seat cushion is disassembled, a new trim cover installed, a seat side shield removed or an OCS service kit is installed. A scan tool is used to trigger the active command to carry out rezeroing of the OCS system.
- Make sure the seat is completely assembled before rezeroing.
- The following precautions must be taken before rezeroing the OCS system:
- Make sure the OCS system components are connected and no faults are present.
- Make sure the OCS system is not at a temperature below 0 °C (32°F) or above 45°C (113°F) when initiating the rezeroing process. If the vehicle has been exposed to extreme cold or hot temperatures, the vehicle must be exposed and kept at a temperature within the limits, 0°C to 45°C (32°F to 113°F) for a minimum of 30 minutes.
- Make sure nothing is present on the passenger seat before rezeroing and nothing is placed on the seat during the rezeroing process.
- Make sure a minimum 8 second time period has passed after cycling the ignition switch ON before the rezeroing process.
NOTE:
- For best results in rezeroing, the OCS system should be at or near room temperature, 10°C to 29°C (50°F to 85°F).
- The heater mat on the front passenger seat cushion is not serviceable separately. If a new heater mat is needed on the front passenger seat cushion a new occupant classification sensor (OCS) service kit, equipped with a heater mat, must be installed.
- If the first attempt to rezero the OCS system is unsuccessful, a second attempt must be made.
If the passenger seat backrest was removed, rezero the occupant classification sensor.
- With the front passenger seat empty, use a scan tool to trigger the active command and rezero the occupant classification sensor.
16. NOTE: The ignition switch must be cycled after rezeroing the OCS system.
Cycle the ignition switch from ON to OFF.
All seats
17. Prove out the supplemental restraint system (SRS) as follows:
Turn the ignition key from ON to OFF. Wait 10 seconds, then turn the key back to ON and visually monitor the air bag indicator with the air bag modules installed. The air bag indicator will light continuously for approximately 6 seconds and then turn off. If an air bag supplemental restraint system (SRS) fault is present, the air bag indicator will:
- fail to light.
- remain lit continuously.
- flash.
The flashing might not occur until approximately 30 seconds after the ignition switch has been turned from the OFF to the ON position. This is the time required for the restraints control module (RCM) to complete the testing of the SRS. If the air bag indicator is inoperative and a SRS fault exists, a chime will sound in a pattern of 5 sets of 5 beeps. If this occurs, the air bag indicator and any SRS fault discovered must be diagnosed and repaired.
Clear all continuous DTCs from the restraints control module using a scan tool.
