Rear Side Door Lamp

When the RH or LH rear door is opened, the RH or LH rear side door courtesy lamp illuminates. When the rear side door is opened, the rear side door jamb switch sends two ground signals. The first signal is a door jamb input to the BCM that wakes the BCM. When the BCM wakes up it will then energize the delayed interior lamps relay, suppling voltage to the rear side door courtesy lamp. The rear side door jamb switch also provides a second ground for the rear side door courtesy lamp and the lamp will illuminate. The BCM also energizes the interior lamps relay illuminating the illuminated entry lamps
