Ambient Lighting
The HVAC module provides the power and ground to the ambient lighting system, while the touchscreen is used to cycle through the different color variations or turn the ambient lighting feature on or off. There are 4 LEDs (red, blue, green and white) housed within each LED assembly. By illuminating various color combinations, the LEDs are able to produce 7 different colors of ambient light.
The ambient lighting LEDs provide illumination to the:
- Cup holders (located in the center console)
- Storage compartment/map pocket (located in the center console)
- Front footwells (located under the instrument panel)
- Rear footwells (located in the rear of the center console)
- Inside pull handles (located in each door trim panel)
- Door map pockets (located in each door trim panel)
The APIM uses software to monitor the user interface from the FDIM. Based on the ambient lighting system selections made using the touchscreen, the APIM sends ambient light color request and ambient light intensity request messages over the communication network for color and brightness settings. The HVAC module retains the last color and brightness setting between uses.
The BCM transmits parking lamps on, illuminated entry/exit feature active, and open door information over the communication network to the HVAC module.
Based on the input received from the FDIM (user preferences) and the BCM (parking lamps on, illuminated entry/exit, open door) over the communication network, the HVAC module provides voltage to the ambient lighting LEDs. The HVAC module also provides the ground source for the ambient lighting LEDs.
