Inadvertent Load (Battery Rundown) Protection

The BCM has a feature called inadvertent load protection, which prevents battery rundown. The BCM de-energizes the protected battery voltage output courtesy lights circuit in 9-11 minutes after the ignition switch has been turned from the ACC or the RUN position to the LOCK or the OFF position when there is no BCM activity.

The BCM restores power to the protected battery voltage output courtesy lights circuit under the following conditions:
^ Turning the ignition switch from the LOCK or the OFF position, to the ACC or the RUN position.
^ Removing the key from the ignition lock cylinder.
^ Opening any vehicle door.
^ Turning the dimmer switch to the DOME position.
^ Activating 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 the key, BCM type 4 only.

The inadvertent battery power rundown protection feature is mileage-sensitive. Vehicles with less than 15 (24 km) total accumulated miles km) have a 2 minute and 32 second - 3 minute and 18 second time-out instead of a 10 minute time-out.
