This guide explains what it means when the Cadillac ABS light stays on, common problems, and how to troubleshoot the Anti-lock Brake System (ABS).

Symptoms

  • Longer stopping distance,
  • Service Stabilitrak Warning Message

  • Traction control and stability lights ON

When your ABS fails, you may also get a warning message asking you to service ABS, Traction Control, and Stabilitrak.

Why is my Cadillac ABS light on?

A faulty ABS wheel speed sensor is the most common problem that triggers the ABS light to stay on in a Cadillac vehicle. Cadillac vehicles have four ABS wheel speed sensors, one for each wheel. To find out which is faulty, follow the steps below to read the codes from the ABS module.

Possible problems that can trigger the ABS light on a Cadillac include:

  • A faulty or dirty wheel speed sensor,
  • Defective steering angle sensor,
  • Damaged wires,
  • Bad ABS module
  • Blown fuse
  • Bad ABS relay

Any of these issues can trigger the Cadillac ABS light to stay on.

How to Read and Reset Cadillac ABS Light

You must read the ABS module’s fault codes to determine why your Cadillac ABS light is on. Your Cadillac dealer, a local auto mechanic, or yourself can perform this procedure.

In this guide, we will show you how to read fault codes from the ABS module of your Cadillac. Once you get the codes, you must fix the related problem before resetting the ABS light.

Don’t use a generic OBD-II scanner. A generic scanner will display no error codes even if the ABS light is on. For this procedure, an ABS Scanner is needed.

Suppose your scanner cannot communicate with the ABS module. In that case, it is possible that the ABS module is defective and needs to either be replaced, which can be an expensive repair or use a third party that provides Cadillac ABS Module Repair Service on eBay.

    It really is dangerous! I always advise people to get this checked asap. You don’t want a problem to occur if you are on the highway. However, I am curious about your issue? Did you finally get a replacement or did you just get your sensors replaced?

    My Cadillac CTS abs light turns on randomly. My brakes will stop working and are very hard to press. I took it into a mechanic and he said that I need a replacement master cylinder. The brake sensor is the problem and from what I’ve read, most people with this car have this same problem. The problem will occur while driving, ABS light come on, Brakes stop working. Very dangerous.
