These codes are on because the steering wheel angle sensor needs to be replaced.

U1000-00 - CAN Communication Malfunction:

C1841-13 - VSA (Vehicle Stability Assist) Sensor Malfunction:

Here is how the job is done to help fix the problem, also clear the codes once the repair is completed. I have included the CAN bus wiring diagrams as you requested. Check out the images (below). Please upload pictures or videos in your response of any problems so we can see what to help you with.

I reprogrammed the steering angle sensor, the fault does not show up again, but I do still have the AWD light coming on and off in different intervals.

Let me provide new codes I have.

Hi Ken, please help get me diagram for the can high and can low for this fault, so I can follow the can bus network to see where the communication ends.
