Metalp3n Report post Posted January 8 Recently bought a 2015 Lincoln MKX, where I am preemptively doing the water pump so I can have some peace of mind for the next couple of years. The 2015 is running Sync 2 (have to check which version, website thinks its 3.8). I noticed that the ambient lighting, while working perfectly across the cupholders and footwells and properly changing colors, doesn't work in the doors. The ONLY color that the doors can display is Blue. Changing to light blue, or purple, simply changes the brightness of the blue. Red, white, green, orange - simply show nothing on the doors. The doors do not change color when opened either, but I am unsure that the 2015 MFT system does that - as my as-built data doesn't show that as an option at all. What should I start looking at to try to narrow this issue down? Or is this how the ambient lighting is meant to function on this model year? Share this post Link to post Share on other sites

Haz Report post Posted January 8 From the 2015 MKX Workshop Manual... Ambient Lighting The ambient lighting subsystem provides illumination to the center console cupholders, the storage bin, the door map pockets, the door pull handles, the door release handles, and the front and rear footwells for illuminated entry or when the ignition is in run with the parking lamps on. The ambient lighting is controlled using the touch screen display in the center of the instrument panel. When the illuminated entry feature is active, the ambient lighting defaults to a pre-set color and brightness setting. When all the doors are closed and the illuminated entry is no longer active, the ambient lighting returns to the last color and brightness setting that was set by the operator. The touch screen display is used to select one of 7 color combinations or turn the ambient lighting feature on or off. The ambient lighting system retains the last color setting and brightness between uses. For vehicles with memory seats, the ambient lighting color can also be set to correspond to the Driver 1 or Driver 2 settings. and... Ambient Lighting The HVAC module controls the ambient lighting system. When requested, the HVAC module provides voltage and ground to the LEDs. There are 3 LEDs (Edge) (red, blue and green) or 4 LEDs (MKX) (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 HVAC module receives input from the Accessory Protocol Interface Module (APIM) and the Body Control Module (BCM) over the communication network for color and brightness settings. The display interface in the center of the instrument panel is used to cycle through different color variations or turn the ambient lighting feature on or off. The APIM communicates messages over the High Speed Controller Area Network (HS-CAN) to the Body Control Module (BCM) . The BCM gateways the messages to the HVAC module over the Medium Speed Controller Area Network (MS-CAN) . The HVAC module retains the last color and brightness setting between uses. and... Door Panel Ambient Lighting Wiring Diagram We've always run "white" as our Ambient selection, so I had to do a test to assess the other colors' behavior. All colors shown in the MFT color-carousel do display correctly in all Ambient locations on our MKX, including the door map pockets. When an Ambient color other than "white" is selected and the a door is opened, all locations' displayed Ambient color changes to "white", consistent with the Workshop Manual description. I need to do a more digging through wiring diagrams before I can offer additional comment. Good luck! Share this post Link to post Share on other sites

I can comment that when it's night time, my ambient lighting does not react to the door being opened/closed. However when it is daytime, and I open a door, my ambient lighting turns on and then turns off. I will have to confirm, but I believe it turns on using the setting in MFT, and not default white. Will need to play with it. I also wonder if it has anything to do with the car having only a MyKey, and no Admin Keys currently. Have to go get new keys programmed after the water pump and see if that changes any behavior. Share this post Link to post Share on other sites

Can confirm - for me when I open the door during the daytime my ambient lighting turns on, onto the custom setting set in MFT. Not white. When it does this - everything functions the same (doors are blue, everything else is the custom set Purple). I reached out to the previous owner, and he said this just randomly started happening once. He just set his ambient color to Blue and never thought about it again. Should have a USB to OBD wire in tomorrow, and water pump done by Thursday. Will then get into Forscan and see what's set there for the lighting. Share this post Link to post Share on other sites
Metalp3n Report post Posted February 5 @Haz would you mind sharing the wiring diagram from the dimmer buttons by the headlight switch if you have it? A new symptom kicked in today. Dimming the interior lights, entirely deactivates the ambient lighting. Whether it's set to ON or OFF in MFT - they all just don't turn on. Have to raise brightness back to full, and then let car entirely shut down and restart. Then my blue ambient lighting is back lol. Just want to see what role that switch plays with this.
