How are you getting the codes, doesn't look like any ABS code I've seen.
I own a Monaco, in my drivers side front electrical bay there is an ABS diagnostic module that I use to get codes. This is the procedure that is in my manual
- Turn key on without starting
- Wait ~5 seconds
- Press brake pedal 1 time
- Go outside and press the small black button on the module, press for LESS then 2 second.
- At that point it will go through a diagnostic routine and will blink a code on the small LED bulb next to the button. It will blink two codes
- A 1-1 code means all is good.
Here are the document that I use, you may have a different system. Find out the system you have and search for a trouble shooting guide. Codes start on page 26, it identifies the location and potential problem. Last code I had was a 2-1, front steer wheel gap. Removed, cleaned, and reinstalled.
