Circuit Description
Battery rundown protection (Inadvetent Power) is controlled by the BCM for all
devices powered by circuit 1732. The devices include the glove compartment
lamp, rear dome lamps, the cargo lamp, map lamps, reading lamps, and sunshade mirror
lamps.
Important: To prevent battery rundown on newly delivered vehicles, inadvertent power is
limited to 3 minutes until the vehicle mileage exceeds 24 kilometers
(15 miles).
Should any device remain ON, the BCM will turn inadvetent 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/lift gate operation, or
a driver/passenger door open/close. Inadvertent power shutoff is disabled in ignition
RUN or START.
