Safing Sensor: Description and Operation

The air bag diagnostic monitor is mounted on the center tunnel under the instrument panel and performs the following functions:
^ signals the inflators to deploy the air bags in the event of a deployable crash.
^ monitors the Air Bag Supplemental Restraint System (SRS) for faults.
^ illuminates the air bag indicator if a fault is detected.
^ flashes the air bag indicator to indicate the Lamp Fault Code (LFC) detected.
^ contains an internal safing sensor which is not serviced separately.

The air bag diagnostic monitor 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 close. The backup power supply will deplete its stored energy approximately 3 minutes after the battery ground cable is disconnected.
