Service Precautions

These precautions should be observed when working with SIR systems:

• Disable SIR system before servicing any SIR system 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 .
• Wait about 2 minutes after disabling SIR system before servicing. System maintains SIR system voltage for about 2 minutes. Servicing SIR system before 2 minutes have passed may cause accidental air bag deployment and possible personal injury.
• After repairs, ensure AIR BAG indicator light is working properly and no system faults are indicated. See SYSTEM OPERATION CHECK .
• Always wear safety glasses when servicing or handling an air bag.
• Inflator module must be stored in its original special container until used for service. It must be stored in a clean, dry place, away from sources of extreme heat, sparks or high electrical energy.
• When placing a live inflator module (air bag module) on a bench or other surface, always face air bag and trim cover up, away from surface. This will reduce motion of module if accidentally deployed.
• After deployment, air bag surface may contain deposits of sodium hydroxide, 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.
• At no time should any electrical source be allowed near inflator on back of inflator module.
• When carrying a live inflator module, trim cover should be pointed away from your body to minimize injury in case of accidental deployment.
• DO NOT probe a wire through insulator; this will damage wire and eventually cause failure due to corrosion.
• When performing electrical tests, prevent accidental shorting of terminals. Such mistakes can damage fuses or components and may cause a second fault code to set, making diagnosis of original problem more difficult.
• When using diagnostic charts to diagnose SIR system, under no circumstances should a volt/ohmmeter, test light or any type of electrical equipment not specified by manufacturer be used.
• If SIR system is not fully functional for any reason, vehicle should not be driven until system is repaired. DO NOT remove bulbs, modules, sensors or other components or in any way disable system from operating normally. If SIR system is not functional, park vehicle until repairs can be made.
