SERVICE PRECAUTIONS
Observe the following precautions when servicing 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-54002-S05860760772001011600000) .
- 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 «AIR BAG RESTRAINT SYSTEM»(ref-33905) article.
- 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 AIR BAG RESTRAINT SYSTEM article.
SPIRAL CABLE
Spiral cable must be correctly adjusted to ensure proper air bag operation. Ensure front wheels are in a 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 1/2-3 turns and ensure marks align and are visible through inspection hole. (Scheme 8)
Scheme 8
STEERING WHEEL & AIR BAG
Note. See DISABLING & ACTIVATING AIR BAG SYSTEM .
Scheme 9
- Ensure wheels are in straight-ahead 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 9) Pull steering wheel pad assembly from steering wheel and disconnect electrical connector.
- Remove steering wheel pad assembly (air bag) from steering wheel. Place steering wheel pad assembly (air bag) on flat surface with pad assembly facing upward. WARNING: Pad assembly MUST face up on level surface. If assembly is stored face down, accidental air bag deployment could propel assembly and cause serious bodily injury.
- Remove lock nut and washer. Mark steering shaft and steering wheel for installation reference. Install steering wheel puller and remove steering wheel from shaft.
- Prior to installation, ensure spiral cable (located on combination switch) is properly aligned. See «SPIRAL CABLE»(ref-54002-S23082358932001011600000) under ADJUSTMENTS. To complete installation, reverse removal procedure. Tighten steering wheel nut to specification. See «TORQUE SPECIFICATIONS»(ref-54002-S14737407122001011600000).
- After spiral cable is aligned and steering wheel pad assembly (air bag) is installed, ensure proper operation of air bag system by turning ignition switch to ACC or ON position. AIR BAG warning light should illuminate, then turn off after about 6 seconds.
- If AIR BAG warning light remains on for more than 6 seconds, air bag system is malfunctioning and needs repair. If AIR BAG warning light illuminates with ignition off, a short circuit may be present in AIR BAG warning light circuit.
