Explorer 2WD V6-245 4.0L VIN X SFI (1999)
Standby Power Supply: Description and Operation
The Restraints Control Module (RCM) includes a backup power supply. This feature provides sufficient backup power to deploy the air bags in the
event that the ignition circuit is damaged in a collision before the safing and air bag sensors determine that a deployment is required. The backup power
supply will deplete its stored energy approximately one minute after the battery ground cable is disconnected.
