B255D CADILLAC Description
The Body Control Module (BCM) supplies battery voltage to accent lighting lamps via the accent lamp control circuit.

The accent lighting will remain illuminated until all doors are closed and the ignition is OFF. The accent lighting remains illuminated with the ignition ON.
