SERVICE PRECAUTIONS
Observe the following precautions when servicing Supplemental Restraint System (SRS)
- Disable SRS before servicing any SRS or steering column component. Failure to do this could result in accidental air bag deployment and possible personal injury. See «DISABLING & ACTIVATING AIR BAG SYSTEM»(ref-127934-S34184248412001103100000) .
- Remove air bag sensor assembly/center air bag sensor and front air bag sensors if repairing the vehicle requires impacting (shocking) the vehicle.
- Replace dropped, cracked, dented or otherwise damaged components.
- DO NOT expose front air bag sensors, air bag sensor assembly/center air bag sensor or steering wheel pad (air bag module) directly to heat or flame.
- Information labels are attached to air bag components. Follow all notices on labels.
- After work on SRS is completed, check air bag warning light to ensure system is functioning properly. See appropriate AIR BAG RESTRAINT SYSTEMS article in ACCESSORIES & EQUIPMENT.
- Always wear safety glasses when servicing or handling an air bag.
- When placing a live air bag on a bench or other surface, always face air bag and trim cover upward, away from surface. This will reduce motion of module if it is accidentally deployed.
- Carry a live air bag module with trim cover (air bag) pointed away from your body to minimize injury in case of accidental deployment.
- If SRS is not fully functional for any reason, vehicle should not be driven until system is repaired and becomes operational. DO NOT remove bulbs, modules, sensors or other components or in any way disable system from operating normally. If SRS is not functional, park vehicle until it is repaired and functions properly.
DISABLING & ACTIVATING AIR BAG SYSTEM
| WARNING | Back-up power supply maintains SRS voltage for about 90 seconds after battery is disconnected. After disabling SRS, wait at least 90 seconds before servicing SRS to prevent accidental air bag deployment and possible personal injury. |
DISABLING SYSTEM
Turn ignition switch to LOCK position. Disconnect and shield negative battery cable. Wait at least 90 seconds before working on system. Remove steering wheel pad (air bag module). See STEERING WHEEL & AIR BAG under REMOVAL & INSTALLATION.
ACTIVATING SYSTEM
Install steering wheel pad. Reconnect negative battery cable. Perform system operation check. See appropriate AIR BAG RESTRAINT SYSTEMS article in ACCESSORIES & EQUIPMENT.
SPIRAL CABLE
On vehicles equipped with air bag system, spiral cable must be correctly adjusted to ensure proper air bag operation. Ensure front wheels are in straight-ahead position. Turn spiral cable (located on combination switch) counterclockwise by hand until it becomes difficult to turn. Turn spiral cable clockwise about 2.5 turns and ensure marks align. (Scheme 12)
Scheme 12
STEERING WHEEL & AIR BAG
Note. See DISABLING & ACTIVATING AIR BAG SYSTEM .
Scheme 13
- Ensure front wheels are in straight-ahead position. Turn ignition switch to LOCK position. Disconnect and shield negative battery cable.
- Remove screw covers, screws and lower instrument cluster trim panel(s). Loosen steering wheel pad Torx screws until groove along screw circumference catches on screw case. (Scheme 13)
- Pull steering wheel pad from steering wheel, and disconnect air bag electrical connector. Remove steering wheel pad. Place steering wheel pad on flat surface with pad cover facing up. WARNING: Place steering wheel pad assembly on workbench with pad surface facing up. If assembly is stored face down, accidental air bag deployment could propel assembly and cause serious bodily injury.
- Disconnect electrical connector. Mark steering wheel and steering shaft for installation reference. Remove steering wheel nut. Use appropriate puller to remove steering wheel.
