Restraints and Safety Systems: Service Precautions

CUSTOMER CAUTIONS
Failure to carry out service operations in the correct sequence could cause the airbag system to be deployed unexpectedly during servicing, and a serious accident to occur. Further, if there is a mistake in servicing the airbag system, it is possible that the airbag may fail to operate when required. Before performing service (including removal or installation of parts, inspection or replacement), be sure to read the items carefully, then follow the correct procedures described in the repair information.

1. Work must be started approx. 30 seconds or longer after the ignition switch is turned to the LOCK position and the negative (-) battery cable is disconnected. (The airbag system is equipped with a back-up power source. If work is started within 30 seconds after disconnecting the negative (-) terminal cable of the battery, the airbag may be operative.) When the negative (-) terminal cable is disconnected from the battery, the clock and audio systems memories will be erased. Before starting work, record the setting of the audio memory system. When work is finished, reset the audio system as before and adjust the clock.
2. Malfunction symptoms of the airbag system are difficult to confirm, so diagnostic codes become the most important source of information when troubleshooting. When troubleshooting the airbag system, always read the diagnostic codes before disconnecting the battery.
3. Never use airbag parts from another vehicle. When replacing parts, replace them with new parts.
4. Never attempt to disassemble and repair the airbag modules, SRSCM, clock spring and airbag wiring harness in order to reuse it.
5. If the SRSCM or airbag module has been dropped, or if there are cracks, dents or other defects in the case, bracket or connector, replace them with new ones.
6. After work on the airbag system is completed, reset the airbag warning lamp.
