Front Seat Backrest - Driver Seat Disassembly and Assembly

FRONT SEAT BACKREST - DRIVER SEAT DISASSEMBLY AND ASSEMBLY

Disassembly Note

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. Failure to follow these instructions may result in personal injury.
- 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. Failure to follow these instructions may result in personal injury.
- 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. Failure to follow these instructions may result in personal injury.
- 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 afterward. Failure to follow these instructions may result in personal injury.
- Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury. Failure to follow these instructions may result in personal injury.
- Vehicle sensor orientation is critical for proper system operation. If a vehicle equipped with an air bag supplemental restraint system (SRS) is involved in a collision, inspect the sensor mounting bracket and wiring pigtail for deformation. Replace and properly position the sensor or any other damaged supplemental restraint system (SRS) components whether or not the air bag is deployed. Failure to follow these instructions may result in personal injury.
- 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.

Refer to the appropriate vehicle workshop manual to determine location of the front air bag sensors.

The side air bag 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). Failure to follow these instructions may result in personal injury.

- The restraint system diagnostic tool is for restraint system repair only. Remove from vehicle prior to road use. Failure to remove could result in injury and possible violation of vehicle safety standards.


NOTE:
- If a seat equipped with a seat-mounted side air bag system is being repaired the air bag system must be deactivated per the deactivation procedure contained in AIR BAG AND SAFETY BELT PRETENSIONER SUPPLEMENTAL RESTRAINT SYSTEM (SRS) of the appropriate car/truck service manual.
- Restraint system diagnostic tools must be installed under the seats in the side air bag to floor connector.
- Diagnostics or repairs are not to be carried out on a side air bag system or a safety belt pretensioner (if equipped) with the seat in the vehicle. Prior to attempting to diagnose/repair the side air bag system or a safety belt pretensioner (if equipped) the seat must be removed from the vehicle and the restraint system diagnostic tool must be installed in side air bag connector at the floor connector. The restraint system diagnostic tool must be removed prior to operating the vehicle.
- Diagnostics may be carried out on seat systems other than the side air bag system or a safety belt pretensioner (if equipped) (lumbar, climate controlled, heated, power seat track) with the seat installed in the vehicle as long as the restraint system diagnostic tool is installed under the seat in the side air bag to floor connector.
- After diagnosing/repairing a seat system the restraint system diagnostic tool must be removed before operating the vehicle.
- A repair is made by installing a new part only. If a new part is installed and the new part does not correct the condition, install the original part and carry out the diagnostic procedure again.
- If a side air bag deployment took place, a new seatback pad, trim cover, and side air bag module must be installed. A new seatback frame should be installed if necessary.
