Updated 2 weeks 1 day ago
Is your Cadillac ABS or traction control light staying ON? On your Cadillac dashboard, you may also get a warning messages asking you to service ABS, Traction Control and Stabilitrak. If the ABS light stays on in your Cadillac the Anti-lock Braking System (ABS) may not be operating properly.
A faulty or dirty wheel speed sensor, defective steering angle sensor, damaged wires, bad ABS module can all trigger a Cadillac ABS light to stay on. The concern with Cadillac ABS light staying on is that it may take longer to bring the car to a complete stop especially on slippery roads or during hard braking when wheels lock up.
A fault code is stored in your Cadillac ABS module. To find out why your Cadillac 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 Cadillac dealer, a local auto mechanic. You can also read Cadillac 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 Cadillac. If your scanner cannot communicate with the ABS module, it is possible that the ABS module is defective and it needs to either be replaced which can be an expensive repair or use a third party that provides Cadillac ABS Module Repair Service.Back to top
