Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Ambient Lighting - MKZ
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.
