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?

Hi, I do not have an AWD code showing on the scanner. Also, I do not have a check engine light 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.

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
