Help with ambient lighting retrofit

Ford SYNC 3 Support

Hello,

I would like to seek assistance regarding a modification I made to my 2022 Escape Titanium HEV. Initially, the vehicle only had blue ambient lighting in the footwells and door handles. After examining the electrical schematics, I discovered that all the LEDs were originally connected to the LIN circuit, allowing me to adjust the brightness of the blue color. This led me to believe that upgrading to a multi-color lighting system was feasible.

I successfully replaced the footwell LEDs with color ones by obtaining the appropriate LEDs from Ford. The replacement process was as simple as plug and play. However, I needed to make adjustments to the APIM (Accessory Protocol Interface Module) to enable the color ambient light screen. I accomplished this successfully, and now I can change colors for the footwell lighting.

7D0-06-01
A07E → 807E

7D0-01-02 (no changes needed)
224B 0406 84D5

Now, I am faced with a challenge regarding the door handles leds. I managed to find a Ford part number that includes the connector, harness, and multi-color LED (actually this led is exactly the same as the one I got for the footwells) . The connector is identical to the one originally installed on the doors, as well as the new LED pinout .
However, after disassembling the door and replacing the blue LED with the new multi-color LED, I noticed that it does not turn on at all. I have checked the voltages and polarity, and everything appears to be normal. The new LED has the same wiring configuration (voltage-LIN-ground), but it remains unresponsive. Interestingly, when I reinstalled the old blue LED, it turned on without any issues.
Any assistance would be greatly appreciated.

Thank you.

I believe the Door lights are run off the Drivers door(DDM) and Passenger door(PDM) modules. You may need to check the settings there.

BCM settings.
Look for this:
726-45-01 xxxx xx** xx--
AmbientLighting_Cfg:
00=Amb Only
01=Disabled
02=Single_Col
03=WF_And_Amb
04=WF_Only

Thanks. I thought so too but looking at my truck schematics, door leds go straight to BMC via LIN08. Footwell LEDs use a different LIN line than the doors

Thanks. I do suspect there’s something on the BCM that needs to be reconfigured but my asbuilt data for this module only goes up to 726-28-01

Can you post your asbuilt for the BCM?

Sure thing

This looks like a C1CMA BCM asbuilt. I don’t have info on C1CMA. I’ve been looking thru the usual Escape/Kuga/Focus forums and can find nothing useful.

You could always try moving the door lights to LIN11.

Thanks.

1- will adding more LEDs to the other LIN line represent a overcharge risk?
2- how does that Lightning strategy work on this type of BCM? How come footwells react differently than doors even though both have a LIN line?

  1. No. All ambient light modules are supplied by the same power.
  2. This is a safety feature for the doors. When you open a door, you can change the light to like red or another color. This is commonly adjustable in CGEA 1.2 and 1.3 vehicles. It should be adjustable in C1CMA vehicles if we could decipher the settings for the BCM. For lack of that, just adding the doors to the rest of the system is an option.

Thanks for the feedback. I’ll consider moving to LIN11 at the BCM
