Ambient Lighting

WARNING: This page is about a different car, the 2016 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.

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 3 LEDs (red, blue and green) 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:

cupholders (located in the center console)
storage bin (located in the center console)
front footwells (located under the instrument panel)
rear footwells (located in the rear of the center console)

The APIM uses software to monitor the user interface from the touchscreen. 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 FCIM (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.
