Dome/Rear Reading Lamps
2000 Saturn LS2 V6-3.0L VIN RSECTION Dome/Rear Reading Lamps
Dome and rear reading lamp operation is through the Body Control Module (BCM) providing ground to circuit 156. When manually operated by their respective local switches, the dome and rear reading lamps are grounded through circuit 450 and the right body ground splice pack.
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 three minutes until vehicle mileage exceeds 15 miles.
