Air Bag Deactivation Procedures: Other Lexus LX J100

SPECIAL CARE DURING MECHANICAL REPAIRS

Note. When the battery is disconnected, vehicle computer and memory system may lose data. Driveability problems may exist until computer systems have completed a relearn cycle.

In some instances, it may be necessary to remove steering column or instrument panel to gain access to blower motor housing, heater assembly, evaporator assembly, or other A/C-heater system related components. Observe manufacturer service precautions when working on a vehicle equipped with an air bag system. See appropriate manufacturer's SERVICE PRECAUTIONS.

Electrical sources should never be allowed near inflator on back of air bag module. Never probe air bag system electrical wires with analog volt-ohmmeter or test light. Always disable air bag system before servicing vehicle. See appropriate DISABLING & ACTIVATING AIR BAG SYSTEM procedure. Failure to do so could result in accidental air bag deployment and possible personal injury.

If air bag system is not fully functional for any reason, DO NOT drive vehicle until system is repaired and is again operational. DO NOT remove bulbs, modules, sensors or other components, or in any way disable system from operating normally. If air bag system is not functional, park vehicle until system is repaired and functions properly.

SERVICE PRECAUTIONS

Observe these precautions when working with air bag systems and seat belt pretensioners (if equipped)

1. Disable SRS before servicing any SRS, instrument panel or steering column component. Failure to do this could result in accidental air bag deployment, causing personal injury and/or vehicle damage. See «DISABLING & ACTIVATING AIR BAG SYSTEM»(ref-149354-S00168830532002100500000) .
2. Wait at least 3 MINUTES after disabling air bag system. A back-up power circuit capacitor (in SRS control unit) maintains system voltage for about 3 minutes after battery is disconnected. Servicing air bag system or seat belt pretensioners before 3 minutes may cause accidental air bag deployment and possible personal injury.
3. After an accident, all SRS components, including wiring harnesses and brackets, must be inspected. If any components are damaged or bent, they must be replaced, even if air bag did not deploy. Check steering column, knee bolster, instrument panel steering column reinforcement plate and lower brace for damage. DO NOT repair any component or wiring. If components or wiring are damaged or defective, replacement is required.
4. Carefully inspect all SRS components before installation. DO NOT install any component that shows signs of being dropped or improperly handled, such as dents, cracks or other deformities.
5. DO NOT install SRS components previously installed on another vehicle. When replacing SRS components, use only NEW, manufacturer supplied components.
6. DO NOT expose air bags to temperatures exceeding 200°F (93°C).
7. DO NOT spill water or oil on air bags or side impact sensors.
8. Always wear safety glasses when servicing SRS or handling an air bag or seat belt pretensioner (if equipped).
9. DO NOT attempt to disassemble air bag assembly, cable reel, or seat belt pretensioner (if equipped). Neither component has any serviceable or reusable parts.
