Service Precautions
Observe these precautions when working with air bag systems and seat belt pretensioners (if equipped):
- Disable SRS before servicing any SRS or steering column component. Failure to do this could result in accidental air bag deployment, possibly causing personal injury. See DISABLING & ACTIVATING AIR BAG SYSTEM .
- Wait about 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 deployment and possible personal injury.
- After an accident, all SRS components, including wiring harness 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 service/repair any component or wiring. If components or wiring are damaged or defective, replacement is required.
- Always wear safety glasses when servicing SRS or handling an air bag or seat belt pretensioner (if equipped).
- DO NOT attempt to disassemble air bag assembly or seat belt pretensioner (if equipped). Neither component has any serviceable or reusable parts.
- A replacement air bag assembly must be stored in its original special container until used for service. Special container must be stored in a clean, dry place, away from sources of extreme heat, sparks and high electrical energy.
- When placing a live air bag assembly on a bench or other surface, always face air bag and trim cover up, away from surface. This will reduce motion of air bag assembly if accidentally deployed.
- After deployment, air bag assembly is very hot. Wait 30 minutes before handling.
- After deployment, air bag surface may contain deposits of sodium azide and potassium nitrate, which can irritate skin. Always wear safety glasses, rubber gloves and long-sleeved shirt during clean-up, and wash hands using mild soap and water. Follow correct disposal procedures.
- DO NOT allow any electrical source near inflator on back of air bag assembly or near 3-pin connector of seat belt pretensioner.
- When carrying a live air bag assembly, trim cover pad should be pointed away from your body to minimize injury in case of accidental air bag deployment.
- DO NOT probe any wire through insulator; this will damage wire and eventually cause failure due to corrosion.
- When performing electrical tests, always use test harnesses recommended by manufacturer. DO NOT connect tester probes directly to component connector pins or wires.
- DO NOT use any type of electrical equipment other than that specified by manufacturer.
- If SRS is not fully functional for any reason, vehicle should not be driven until system is repaired. DO NOT remove any component or in any way disable system from operating normally. If SRS is not functional, park vehicle until repairs can be made.
