Battery Rundown Protection

Battery rundown protection (inadvertent power) is controlled by the BCM for all devices powered by circuit 1732. The devices include glove compartment lamp, rear dome lamps, cargo lamp, map lamps, reading lamps, sunshade mirror lamps and courtesy lamps.

Should any device be On, the BCM will turn inadvertent power OFF after 20 minutes to conserve battery energy if there has not been an ignition switch transition to RUN or START, an RKE LOCK or UNLOCK, a decklid/liftgate operation or a driver/passenger door open/close. Inadvertent power shutoff is disabled in ignition RUN or START.

IMPORTANT: To prevent battery rundown on newly delivered vehicles, inadvertent power is limited to 3 minutes until vehicle mileage exceeds 15 miles.
