Hello,
This can be because you have a wheel speed sensor that is out. Can you follow this video to scan the ABS this will tell us whats going on?

Even though the light is not on it may still have codes. This will be an ABS system scan which works the traction control/AWD. You can get a scanner for about $110.00 on Amazon.

Okay, sorry lets try a different approach. Here is the wiring diagram for the all wheel drive unit so we can see how it works. There are three fuses I would check first # 8, 49 and 22 here is a guide to help us check the fuses.
https://www.2carpros.com/articles/how-to-check-a-car-fuse
Here are the fuse panel locations and identification.
If the fuses check out I would see if the encoder motor is getting power and if so I would replace the encoder.
Check out the diagrams (below).
Let us know what happens and please upload pictures or videos of the problem.
Cheers, Ken
