AIR BAG SYSTEM
| CAUTION | Read the following safety precautions before servicing steering columns on vehicles equipped with air bag restraint system. |
Always wear safety glasses when servicing vehicle with air bag and when handling air bag.
Air bag system must be disabled before servicing any air bag component. See DISABLING & ACTIVATING AIR BAG SYSTEM .
When handling air bag module, ensure bag and trim cover are pointed away from your body. This reduces chance of injury in case of accidental air bag deployment. When placing air bag module on bench or other surface, always face air bag and trim cover up, away from surface. This reduces motion of module if accidentally deployed.
Safety precautions must also be observed when handling a deployed air bag. After deployment, air bag surface may contain deposits of sodium hydroxide, a product of inflation gas generant combustion that irritates skin. Always wear gloves and safety glasses when handling air bag. Wash hands with mild soap and water afterward.
DO NOT probe connectors on air bag module. Air bag may deploy causing personal injury.
DO NOT attempt to service air bag module or contact assembly. To correct system malfunctions, replace complete assembly.
After any servicing, ensure AIR BAG light does not indicate any faults.
DISABLING & ACTIVATING AIR BAG SYSTEM
| 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. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery. |
| WARNING | Both driver-side and passenger-side air bag modules must be disabled. |
DISABLING SYSTEM
- Disconnect negative battery cable. Disconnect positive battery cable. Wait one minute. This is the time required for backup power supply in diagnostic monitor to deplete its stored energy.
- Remove instrument panel lower left trim panel, to access electrical connectors. Disconnect electrical connectors. Separate hood latch release cable and handle from steering column panel. Remove heater duct. Remove 2 bolts retaining driver-side air bag to steering wheel. Disconnect driver-side air bag module connector. Attach Air Bag Simulator (Rotunda 105-R0012) to air bag connector to simulate air bag.
- To disable passenger-side air bag, remove glove box. Disconnect passenger-side air bag electrical connector. Attach Air Bag Simulator (Rotunda 105-R0012) to air bag connector to simulate air bag. Connect battery ground. Move front seats to highest and most forward position. Disconnect passenger-side air bag connector.
- Under passenger seat, release connector bracket and remove passenger seat side air bag electrical connector. To disengage connector, slide locking clip and push in release tab. Attach Air Bag Simulator (Rotunda 105-R10012) to air bag connector to simulate air bag.
- Under driver seat, release tab on connector bracket and remove driver seat side air bag electrical connector. To disengage connector, slide locking clip and push in release tab. Attach Air Bag Simulator (Rotunda 105-R10012) to air bag connector to simulate air bag.
ACTIVATING SYSTEM
- Ensure both battery cables are disconnected. Wait one minute. Remove air bag simulators from driver-side air bag, passenger-side air bag and side air bag wiring harness connectors.
- Reconnect driver-side air bag connector to air bag module. Install driver-side air bag module on steering wheel. Tighten nut and washer assemblies to specification. See «TORQUE SPECIFICATIONS»(ref-137461-S27353845082002030600000) .
- Reconnect passenger-side air bag connector to air bag module. Install passenger-side air bag module. Tighten bolts to specification. Install trim panel. Connect positive battery cable. Connect negative battery cable. Check AIR BAG light for system faults.
