B1482

Schematic:

CIRCUIT DESCRIPTION
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.

Should any device remain 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 trunk/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.

DIAGNOSTIC AIDS
