CIRCUIT DESCRIPTION
The Body Control Module (BCM) controls the inadvertent load (battery rundown) protection feature. The BCM de-energizes circuit 1393 and circuit 328 nine to eleven minutes after the ignition switch has been turned from the ACC position or the RUN position to the LOCK position or the OFF position. The BCM restores power to circuit 1393 and circuit 328 when the following actions occur:
- The ignition switch is turned from the LOCK position or the OFF position to the ACC position or the RUN position.
- The key is removed from the ignition.
- Any vehicle door is opened.
- The instrument panel dimmer switch is turned to the DOME position.
- Any interior courtesy light connected to circuit 1393 and circuit 328 is turned on.
- The BCM receives a message to unlock the doors from the Remote Control Door Lock Receiver (BCM type 3 or type 4 only).
- A door is unlocked using a key (BCM type 4 only).

The inadvertent load (battery rundown) protection feature is mileage-sensitive. Vehicles with less than 15 total driven miles have a time-out of 162-198 seconds instead of 10 minutes.

CONDITIONS FOR SETTING THE DTC
The BCM detects a short to B+ or ground in circuit 1393 or circuit 328.

ACTION TAKEN WHEN THE DTC SETS
- The BCM sets the Diagnostic Trouble Code (DTC) 2.
- The inadvertent load (battery rundown) protection feature is disabled when circuit 1393 or circuit 328 is shorted to B+.
- The interior courtesy lights do not turn on when circuit 1393 or circuit 328 is shorted to ground.

CONDITIONS FOR CLEARING THE MIL/DTC
- A short to B+ or ground in circuit 1393 or circuit 328 is no longer present.
- After you complete the repairs, refer to Diagnostic Trouble Code (DTC) Clearing in order to clear the DTC.

DIAGNOSTIC AIDS
- Inspect for a short to B+ in circuit 1393 and circuit 328.
- Inspect for a short to ground in circuit 1393 and circuit 328.
