5 Symptoms of a Bad ABS control module and replacement cost

The anti-lock braking system control module, also known as the ABS control module, works to prevent your wheels from locking up as you’re driving. This is especially important when you must put on the brakes suddenly to prevent an accident or crash. That way, your wheels won’t lose any traction after you apply the brakes. If you’re driving in tough terrains or weather conditions, the only way you’ll be able to survive is with a fully functional ABS control module.

Top 5 Symptoms of a Bad ABS Control Module 

The ABS control module ensures that you drive safely and securely on the road. The worst thing that can happen is to have a bad control module and then find out about it on the road. Below are the top 5 symptoms that will let you know that your ABS control module is bad. Once you find this out, go to a mechanic and get the module replaced right away.

  1. Brake locking–The whole purpose of an ABS control module is to prevent locking of the wheels. If you notice that your wheels are locking up while you’re driving, then this obviously means that your ABS control module is faulty or damaged. Do not wait to fix this problem because it will only get worse and cause a lot more locking on the road as time goes on.
  2. ABS Light – If you have a newer car, then it should have an ABS light on the dashboard. If your ABS control module were to go bad, this dashboard light should come on. The light will likely be an amber color so it will be easy to recognize. However, if you have an older car, then the “check engine” light will be used to indicate this problem instead of the ABS light.
  3. Brake Pedal is Unresponsive – If you put your foot on the brake pedal and the car does not slow down at all, this is obviously a sign that there is a problem. In the beginning, the symptom will start out gradually where you will have to press your foot down on the pedal a couple of times to get it to work. But then as time goes on, you will have to press down more times just to perform one braking function. It will eventually get to the point where it stops working altogether. So, don’t wait for it to get to this point.
  4. Increased Effort w/ Brake Pedal – You may be in a situation where the brake pedal of your vehicle works, but it requires a lot more pressure on your part just to perform a simple braking function. A brake pedal should not require this much pressure. You should be able to just lightly press your foot down on the brake pedal for the braking to work. If you have to increase your effort just to do this, then your ABS control module is bad.
  5. Speedometer Fails– In rare cases where your ABS control module doesn’t work, the speedometer on the dashboard will stop working. Either it will show you an incorrect speed or the needle will just rest at 0 mph. This should be followed by the ABS or check engine light coming on. But even if the light doesn’t come on, a bad speedometer should be reason enough to get your car checked out by a professional.
