component. Failure to do this may result in accidental air bag deployment and possible personal injury. Refer to DISABLING & ACTIVATING AIR BAG SYSTEM. * For about 60 seconds after air bag system is disabled, it retains enough voltage to deploy air bags. After disabling system, wait at least 60 seconds before servicing. * After servicing, always turn ignition on from passenger-side of vehicle in case of accidental air bag deployment. * After servicing, check SRS warning light to verify system operation. See SYSTEM OPERATION CHECK. * Always wear safety glasses when servicing or handling an air bag. * The SRS-ECU 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 and high electrical energy. * DO NOT expose air bag module and clockspring to temperatures greater than 200 F (93 C). * When placing a live air bag module on a bench or other surface, always face air bag module and trim cover up, away from surface. This will reduce motion of module if air bag accidentally deploys. * After air bag deploys, air bag surface may contain deposits of sodium hydroxide, which irritates skin. Always wear safety glasses, rubber gloves and long-sleeved shirt during clean-up. Wash hands using mild soap and water. Follow correct clean-up and disposal procedures. Refer to DISPOSAL PROCEDURES. * Because of critical system operating requirements, DO NOT service any SRS components. Repairs are only made by replacing defective part(s). * DO NOT allow any electrical source near inflator on the back of air bag module. * When carrying a live (undeployed) air bag module, trim cover must be pointed away from body to minimize injury in case of accidental air bag deployment. * DO NOT probe wire harness connector terminals. Instead, use SRS Check Harness (MB991530). * DO NOT probe a wire through insulator, as this will damage it and eventually cause failure due to corrosion. * When performing electrical tests, prevent accidental shorting of terminals. Such shorts can damage fuses or components and may cause a second fault code to set, making diagnosis of original problem more difficult. * Never use an analog volt/ohm meter or test light in place of a Digital Volt/Ohm Meter (DVOM). Use only a DVOM with a maximum test current of 2 mA (milliamps) at minimum range of resistance measurement. Also see SPECIAL TOOLS. * If SRS is not fully functional for any reason, DO NOT drive vehicle until system is repaired and is fully functional. DO NOT remove bulbs, modules, sensors or other components, or in any way disable system from operating normally. If SRS is not functional, park vehicle until repairs are made. SPECIAL TOOLS To avoid air bag deployment when working on SRS, DO NOT use electrical test equipment such as test lights, battery or A/C-powered volt/ohmmeter, or any type of electrical equipment other than those specified by manufacturer.
