Inadvertent Load (Battery Rundown) Protection

The Body Control Module (BCM) has a feature called inadvertent load (battery rundown) protection. The BCM de-energizes circuit 328 and 1393 10 minutes (+/-1 minute) after the ignition switch has been turned from the ACC or RUN position to the LOCK or OFF position.

The BCM restores power to circuit 328 and 1393 when the interior lamps override switch is on (interior courtesy lights enabled) and:
- Turning the ignition switch from the LOCK or OFF position to the ACC or RUN position.
- Removing the key from the ignition lock cylinder.
- Opening any vehicle door.
- Turning the I/P dimmer switch to the DOME position.
- Turning on any of the roof rail reading lights.
- The BCM receives a message from the Remote Control Door Lock Receiver (BCM type 3 or 4 only).
- Locking a door using key (BCM type 4 only).
The inadvertent battery power rundown protection feature is mileage-sensitive. Vehicles with less than 15 miles (24 km) total accumulated miles (km) have a 3 minute (+/- 18 seconds) time-out instead of 10 minutes.
