Service Precautions: Notes

The following precautions should be observed when working with SIR system:

• The SDM maintains sufficient voltage to cause air bag deployment for up to 2 minutes after ignition is turned OFF, battery is disconnected, or fuse powering SDM is removed. In order to begin servicing immediately, inflator modules must be removed from the deployment loop. See DISABLING SYSTEM  .
• After repairs, ensure AIR BAG warning 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 module.
• Air bag 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.
• Air bag modules or SDMs should not be subjected to temperatures above 150°F (65°C).
• Air bag modules or SDMs should not be used if they have been dropped from a height of 3 ft (0.9 m) or greater.
• When placing a live air bag module on a bench or other surface, always make certain that the trim cover (finished side) is up and 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. See DISPOSAL PROCEDURES  .
• At no time should any electrical source be allowed near inflator on back of air bag module.
• DO NOT  apply power to SIR 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 your body to minimize injury in case of accidental deployment.
• DO NOT  attempt to service SDM, front end discriminating sensor, SIR coil assembly, or air bag modules. If defective, these parts must be replaced.
• DO NOT  strike or jolt SDM. Before applying power to SDM, remove any dirt or grease from mounting surface.
• Position SDM horizontally on mounting surface and point arrow on SDM toward front of vehicle.
• DO NOT  probe a wire through insulator; this will damage it 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. See SPECIAL TOOLS  .
• 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.
