HOW DO YOU PULL THE CODES FROM THE MODEDULE??????????
YOU MEAN A OBD2 SCANNER???????
OK THANKS FOR YOUR ADVICE
You'll want to pull the codes from the module, that will help to isolate the issue. Once you have the code, perform the appropriate troubleshooting to find the problem.
You'll need a scan tool that can read the codes in your car. I advise you take it to a repair shop and have it looked at.
Kind of, but not all of them can read ABS codes, so you need one that can read the codes in your ABS module.
