Ambient Lighting
The HVAC provides voltage and ground to the LEDs. There are 3 different color LEDs (red, blue and green) housed within each LED assembly. By illuminating various color combinations, the LEDs can produce 7 different colors of ambient light.
The HVAC module receives input from the APIM and the Body Control Module (BCM) over the communication network for color and brightness settings.
The display interface in the center of the instrument panel is used to cycle through different color variations or turn the ambient lighting feature on or off. APIM communicates messages over the HS-CAN to the Body Control Module (BCM).
The Body Control Module (BCM) gateways the messages to the HVAC module over the MS-CAN. The HVAC module retains the last color and brightness setting between uses.
