2003 Lincoln navigator Advance traction control light. No 4x4
I have a Advance traction control light on. Code U1900 don’t know where to look. To try and fix.
Also when I turn the switch for four-wheel-drive none of my lights pop up on the dash and my car is not going into four-wheel-drive.

The most common cause of the trouble code U1900 is a possible defective instrument cluster or an issue with the trailer brake controller. Other issues can be:
CAN circuit (Controller Area Network) 1908 (WH) open, short to ground, or short to voltage.
CAN circuit (Controller Area Network) 1909 (BK) open, short to ground, or short to voltage.
DLC (Data Link Connector) C251
ABS module
ABS module C135
instrument cluster
instrument cluster C220b
PCM
PCM C175b or C1381b
trailer brake controller
trailer brake controller C2142b
The anti-lock brake system (ABS) module, the instrument cluster, the power train control module (PCM) and the trailer brake controller are all on the CAN. Could be a bad connector somewhere on the CAN.
River or Navigator family, did you guys ever resolve your issue. I am having very similar issues to my 03 Nav as both of you.
