Service Precautions

Observe these precautions when working on SRS:

• SDM maintains sufficient voltage to cause air bag deployment for up to 10 minutes after battery is disconnected. See DISABLING & ACTIVATING AIR BAG SYSTEM .
• After repairs, ensure AIR BAG warning light is working properly and no faults are indicated. See SYSTEM OPERATION CHECK .
• Always wear safety glasses and gloves when servicing or handling an air bag module.
• Use only new parts when replacing SRS system components. Never install used parts from other vehicles.
• Do not install any part that has been dropped, has cracks, dents or other defects.
• Air bag modules must be stored in original special containers until used for service. Store in a clean, dry place, away from sources of extreme heat, sparks, or high electrical energy.
• When placing a live air bag module on a bench or other surface, always make certain that trim cover faces up. 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. Use correct disposal procedures.
• At no time should any electrical source be allowed near inflator on back of air bag module.
• Air bag modules, SDM or clockspring should not be used if dropped from a height of 3 feet (0.9 m) or greater.
• Do not expose air bag modules to temperatures exceeding 149°F (65°C). Do not allow oil, grease or water to contact module.
• Do not apply power to SRS system unless all components are connected or a diagnostic chart requests it, as this will set a diagnostic trouble code.
• When carrying a live air bag module, trim cover should be pointed away from body to minimize injury in case of accidental deployment.
• Do not attempt to service any SRS component. All defective SRS components must be replaced.
• Do not probe a wire through insulator; this damages wire and eventually causes 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 SRS system, under no circumstances should a volt/ohmmeter, test light or any type of electrical equipment not specified by manufacturer be used.
• 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.
