Ambient Lighting - MKZ
WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The Interior Lighting Control Module (ILCM) provides voltage to the LEDs. There are 4 different color 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 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. With each press of the ambient lighting dimmer switch, the ILCM changes the brightness setting of the ambient lighting or turns the ambient lighting feature off. The module retains the last color and brightness setting between uses.
