Standby Power Supply: Description and Operation
The air bag diagnostic monitor includes an internal backup power supply. This feature provides sufficient backup power to deploy the air bag in the
event the battery or battery cables are damaged in an accident before the center air bag and front air bag sensors close. The backup power supply will
deplete its stored energy approximately one minute after the positive battery cable is disconnected.
