Circuit Description
WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
Battery rundown protection, inadvertent power, is controlled by the body control module (BCM). Should any device remain ON, the BCM will turn inadvertent power OFF after 20 minutes to conserve battery energy. If a problem is detected on the inadvertent power supply circuit, this DTC sets.
