Inadvertent Power Timer

The scan tool displays the seconds left before the BCM turns the inadvertent power relay OFF. The BCM uses this feature to protect the battery against inadvertent battery rundown caused by components that are part of the courtesy lamp circuit. The inadvertent power relay is supplied power by the BCM for 2400 seconds (approximately 40 minutes), after the ignition is turned OFF.
