3 years ago, you answered the question by posting a wiring diagram to disconnect the solenoid to disengage the rear wheels and allow the vehicle to remain in front wheel drive only to isolate an issue. In my vehicle listed above SE when I follow your wiring diagram I'm not finding the same layout, so I just want to make sure I am not supposed to be looking at different.

Here are the 4wd wiring diagrams which I think are what you are looking for. Have you run a CAN scan on the system? You can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon here is a video to show you how. You may have an active torque control coupling solenoid that is not working correctly.

Here is one for about $99.00 if you need it:

Check out the images (below). Please let us know what happens. I have included how to change out the active torque control coupling clutch as well.
