B2615 CADILLAC Description
The Body Control Module (BCM) receives a ground signal from the door jamb, lift glass/lift gate if equipped, or courtesy lamp switches requesting courtesy/dome lamp illumination.

Voltage for the courtesy lamp supply voltage circuit as well as the backup lamp supply voltage circuit is from the left instrument panel fuse block fuse directly through the BCM to these circuits.
