SERVICE PRECAUTIONS
Observe the following precautions when servicing air bag system
- Disable air bag system before servicing any air bag system or steering column component. See «DISABLING & ACTIVATING AIR BAG SYSTEM»(ref-4666-S11795037852000071200000) .
- After disabling air bag system, wait at least one minute before servicing. Air bag system voltage is maintained for approximately one minute after system is disabled. Failure to wait one minute before servicing system may cause accidental air bag deployment and possible personal injury.
- Obtain radio code number from customer and deactivate radio anti-theft function (if equipped) before disconnecting battery.
- Because of the critical operation requirements of system, DO NOT service any air bag system component. Repairs are made by replacement only.
- DO NOT use an ohmmeter to check resistance of air bag module, as it may cause air bag deployment.
- When carrying a live (undeployed) air bag module, ensure trim cover is pointed away from your body. This minimizes chance of injury in the event of accidental air bag deployment.
- When placing a live air bag module on any surface, always face trim cover upward to reduce motion of module if it is accidentally deployed.
- If an open circuit is present, replace entire wiring harness. DO NOT attempt to repair wire(s).
- Air bag system clockspring must be aligned in neutral position, since its rotation ability is limited. DO NOT turn steering wheel or column after removal of steering gear.
- A double-lock mechanism is used on clockspring connectors. DO NOT use excessive force when disconnecting connectors, as damage to connector may occur.
AIR BAG DISABLING & ACTIVATING
| WARNING | Wait about one minute after disabling air bag system before servicing. Air bag system voltage is maintained for about one minute after system is disabled. Failure to wait one minute before servicing system may cause accidental air bag deployment and possible personal injury. |
| CAUTION | When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. |
DISABLING SYSTEM
Obtain radio code from customer and deactivate audio anti-theft function (if equipped). Turn ignition switch to LOCK. Disconnect and shield negative battery cable. Wait at least one minute for back-up power supply to be depleted.
ACTIVATING SYSTEM
Reconnect negative battery cable. Turn ignition on. Check AIR BAG warning light to ensure air bag system is operating properly. See SYSTEM OPERATING CHECK . Activate audio anti-theft function (if equipped).
CLOCKSPRING CENTERING
Set front wheels in straight-ahead position. Rotate clockspring clockwise until it stops (DO NOT force). Rotate clockspring 2-3/4 turns counterclockwise. Rotate clockspring further, if necessary, to align arrows on clockspring and outer housing. (Scheme 13)
