Ambient Lighting
The Body Control Module B (BCM-B) monitors the door courtesy lighting, courtesy lighting delay and illuminated exit requests. When a door is opened, the BCM-B turns on all 3 zones of the ambient lighting system. Zone 3 (door scuff plate LEDs) are turned off when any door is closed, or the illuminated entry request is detected by the BCM-B. The other 2 zones are turned off at the same time as the courtesy lighting by the BCM-B if the key is not activated in the ignition switch. The ambient lighting is reactivated when the ignition is placed in the accessory ON or RUN position.
The color of the LEDs always defaults to the last setting in the memory. There are 125 different color combinations that are achieved by adjusting the 3 primary (red, green and blue) colors.
