Updated Monday Apr 23, 2018
Is your Chevrolet ABS light staying ON? If the ABS light stays on the Anti-lock Braking System (ABS) may not be operating properly. Any component including faulty or dirty wheel speed sensor, defective steering angle sensor, damaged wires, bad ABS module etc. can trigger Chevrolet ABS light to stay on.If your Chevrolet ABS light stays on, it may take longer to bring the car to a complete stop especially on slippery roads. With no ABS, Chevrolet wheels can lock up during braking. The first thing that you need to do if your Chevy ABS light is ON, is to check the brake fluid level.
If the level is below the MIN mark add ONLY the brake fluid type noted on the brake fluid cap. Typically it will be DOT 4 Brake Fluid check the cap in your Chevrolet to verify.
If your Chevy ABS light remains ON, a fault code will be stored in your Chevrolet ABS module. To find out why your Chevrolet ABS light is on, you need to read the fault codes form the ABS module. This is a procedure that can be performed by your Chevrolet dealer, the local auto mechanic. You can also read Chevrolet ABS codes yourself if you have the right OBD-II scanner. In this guide, we are going to show you how to read fault codes from the ABS module of your Chevrolet.Back to top
