The common issues that will cause the 2011 GMC Sierra ABS and traction control light to turn on are a faulty wheel sensor, bad ABS module, or low brake fluid levels. The first thing You should do to check to see what could be causing the problem is the brake fluid levels. You can open the hood find the brake fluid reservoir and open to see if its at the recommended levels. Now You will need an OBD diagnostic tool to check to see what error is being coded. If You do not have an OBD tool You can borrow or use one from the local auto-parts store as they have some available for customers to use. The cost for replacements will be on the issue but will range from $200 - $500 depending on parts and labor.

The dealership replaced my speed sensor or wheel sensor and it didn’t help my brake fluid levels up. ?
