Side Air Bag: Service and Repair

SIDE AIR BAG MODULE







Removal

WARNING:
- Always wear eye protection when servicing a vehicle. Failure to follow this instruction may result in serious personal injury.
- 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.

CAUTION: To prevent system failure, it is necessary to carry out the occupant classification sensor (OCS) system reset of the OCS system when a front passenger seat cushion is disassembled, a new trim cover installed or an OCS system service kit is installed. A scan tool is used to carry out the OCS system reset command.

NOTE:
- If a side air bag deployment took place, a new seat back foam pad, trim cover, side air bag module, bracket and nuts, U-nuts and bolts 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 supplemental restraint system (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.
- Driver seat side air bag module shown, passenger seat side air bag module similar.
- 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.

8. CAUTION: Note the position of the wiring harness, to aid installation. An incorrectly routed wiring harness may become damaged when the seat is moved.

Detach the wiring pin-type retainers from seat backrest frame.







9. Remove the bolts and the side air bag module.







Installation

Seats installing a new side air bag module

1. NOTE: When installing a new side air bag module after deployment, install a new module, module bracket, module-to-bracket nuts, U-nuts-to-backrest frame and module and bracket-to-backrest frame bolts.

Install the side air bag module bracket on the side air bag module and install the 2 nuts.
- Tighten the nuts to 6 Nm (53 lb-in).







All seats

2. 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.

- 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.

CAUTION: Make sure the side air bag module wiring harness is not pinched between the side air bag module and the mounting bracket.

Install the side air bag module and the bolts.
- Tighten the bolts to 10 Nm (89 lb-in).







3. NOTE: Note wire routing from removal.

Attach the wiring pin-type retainers to the seat backrest frame.







4. Reposition the seat back foam pad to the seat backrest frame.







5. WARNING: To correctly retain the backrest trim cover, always install 2 hog rings when attaching the backrest trim cover wire to the listing wire in each foam pad window. Failure to follow this instruction may result in the seat side air bag module deploying incorrectly and increases the risk of serious personal injury or death in a crash.

Install the seat backrest trim cover.
1 Install the 2 hog rings per window as shown.
2 Attach the hook-and-loop strips.







6. Attach the seat backrest trim cover inner J-clip.
7. Attach the front seat backrest trim cover J-clip.







8. Fold the backrest trim cover over on each side of the inboard and outboard recliner. Install the plastic rivets attaching the backrest trim cover to the inboard and outboard recliners.
9. Install the front seat backrest.
10. Install the front seat.
11. Repower the SRS.

12. WARNING: Make sure the front passenger seat repair is complete, the seat and all attached components (head restraint, seat side shield, etc.) are correctly assembled, and the seat is correctly installed to the vehicle before carrying out the System Reset. Failure to follow these instructions may result in incorrect operation of the occupant classification sensor (OCS) system and increases the risk of serious personal injury or death in a crash.

CAUTION:
- To prevent system failure, it is necessary to carry out the occupant classification sensor (OCS) system reset when a front passenger seat cushion is disassembled, a new trim cover installed or an OCS system service kit is installed. A scan tool is used to carry out the OCS system reset command.
- To prevent system failure, the following precautions must be taken before carrying out the occupant classification sensor (OCS) system reset:
- Make sure the voltage to the OCSM is above 8.0 volts and less than 18.0 volts.
- Make sure the OCS system is not at a temperature below 6°C (42°F) or above 36°C (97°F) when initiating the OCS system reset 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, 6°C to 36°C (42°F to 97°F) for a minimum of 30 minutes.
- Make sure nothing is present on the passenger seat before carrying out the OCS system reset and nothing is placed on the seat during the process.
- Make sure a minimum 8-second time period has passed after cycling the ignition switch ON before the carrying out the OCS system reset process.

NOTE: If the first attempt to carry out the occupant classification sensor (OCS) system reset is unsuccessful, a second attempt must be made. If the second attempt is unsuccessful, a new OCS system service kit must be installed.

Carry out the OCS system reset active command using the scan tool.

13. Cycle the ignition switch from ON to OFF.

14. NOTE: The ignition switch must be cycled after the OCS system reset.

Cycle the ignition switch from OFF to ON.

15. Prove out the 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 warning indicator with the air bag modules installed. The air bag warning indicator will light continuously for approximately 6 seconds and then turn off. If an air bag SRS fault is present, the air bag warning indicator will:
- fail to light.
- remain lit continuously.
- flash at a 5Hz rate (RCM not configured).

The air bag warning indicator might not light 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 RCM to complete the testing of the SRS. If the air bag warning 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 warning indicator and any SRS fault discovered must be diagnosed and repaired.

Clear all continuous DTCs from the RCM using a scan tool.
