Ambient Lighting

WARNING: This page is about a different car, the 2012 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.

The Interior Lighting Control Module (ILCM) 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 ambient lighting select switch and ambient lighting dimmer switch are inputs to the ILCM. With each press of the ambient lighting select switch, the ILCM cycles through a different color variation or turns the ambient lighting feature off. With each press of the ambient lighting dimmer switch, the ILCM changes the brightness setting of the ambient lighting. The module retains the last color and brightness setting between uses.

The ILCM also receives messages regarding courtesy lamp door ajar status, illuminated entry status, accessory delay status, courtesy lamp delay status, battery saver relay status and ignition status over the network from the BCM. The ILCM uses these inputs to determine when the ambient lighting is turned on to the preset color and brightness setting or to customer-selected color and brightness setting. The color and brightness setting can only be changed when the ignition is in RUN or ACC, the parking lamps are on and all of the doors are closed.
