Standby Power Supply: Description and Operation

The air bag diagnostic monitor Includes an internal backup power supply. This feature provides sufficient back up power to deploy the air bags in the event that the battery or battery cables are damaged in a collision before the air bag sensors close. The backup power supply will deplete its stored energy approximately one minute after the positive battery cable is disconnected.

WARNING:
- The backup power supply energy must be depleted before any air bag component service is performed. To deplete backup power supply energy, disconnect the positive battery cable and wait one minute.

- The air bag simulator(s) must be removed and the air bag(s) reconnected before the system is reactivated.
