Inadvertent Load (Battery Rundown) Protection

The Body Control Module (BCM) has a feature called inadvertent load (battery rundown) protection. The BCM de-energizes circuit 1732 20 (+1- 2) minutes 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 1732 when:
^ 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 IP dimmer switch to the DOME position.
^ The BCM receives a message from the Remote Control Door Lock Receiver.

The inadvertent battery power rundown protection feature is mileage-sensitive. Vehicles with less than 15 (+1- 1.5) total driven miles have a 3 minute (+/- 18 seconds) time-out instead of 10 minutes.
