What Are The Symptoms Of A Bad ABS Control Module?

Brakes are one such important component of every vehicle in the world. The basic principle acing behind brakes is friction. But, when applying brakes, there generates a huge amount of heat to brake pads and caliper. Different type of brakes is vintage drum brakes and modern disc brakes. So, here in this article, we will discuss the symptoms of a bad ABS control module. Let’s begin.

What Is ABS?

The anti-lock braking system on a vehicle is an additional feature found on many modern cars. The ABS is meant to assist prevent wheels from locking during heavy braking situations, preventing the car from skidding or hydroplaning. The ABS is formed from the ABS module and ABS sensors at each wheel. The sensors detect wheel speed and send a message to the ABS module to rapidly pump the brakes when it’s noticed that the vehicle is skidding or has lost traction.

Symptoms Of A Bad ABS Control Module:

Here are the apparent signs which will assist you in detecting an ABS control module issue.

1. ABS Red Light Glows:

This is the only common sign of problems with the ABS. Just remember that the dashboard ABS Light is meant to return for a couple of seconds once you start a vehicle, so don’t panic.

2. Brakes Lock Up:

The ABS is specifically designed to stop any wheel from locking up during heavy braking. So, when an ABS control module fails, you’ll likely notice it when you’re braking heavily. A bad ABS module can behave erratically, making your brakes lock up even under standard braking.

You would possibly even notice unusual behavior from the brakes, like random clicking noises. These also can indicate ABS module failure, which is a symptoms of a bad ABS control module. Here’s something to notice, if one tire is consistently locked, it’d not be the vehicle ABS but a stuck calliper instead.

3. Unresponsive Pedal:

Your pedal may slowly become unresponsive over time. At first, you’ll need to press the pedal a few times to urge some braking action. Eventually, you’ll need to depress multiple times to urge it to figure. This may be the sign of a deteriorating ABS module.

4. Increased Pedal Effort:

With a functional braking system, the pedal needs minimal effort to slow the vehicle. If you notice you would like more pedal effort required to get an equivalent braking force, there might be a drag with the ABS control module. But, again, pedal issues like increased foot effort can mean other things, like worn restraint or a failing brake booster. So make sure to possess your mechanic check everything.

5. Speedometer Failure:

There are rare cases where an ABS control module failure affects the speedometer. First, it’ll either show you the incorrect speed or the needle will rest at 0 mph. Next, the ABS Light or Check Engine Light will likely turn ON as a symptoms of a bad ABS control module.

How To Get Rid Of ABS

The ABS adds a layer of safety when you’re on the road. So keeping it fully functional may be a no-brainer. However, when you encounter ABS issues, whether it’s a drag with the ABS control module or sensor, or if the ABS Light is acting strange, don’t ignore it. Ignoring symptoms of a bad ABS control module, one problem can often create a cascade of other ones.

1. Fixing ABS Glow Light:

If the ABS Light remains glowing, try turning the key off and back on, kind of like rebooting your computer. There could also be some transient issues that confused the ABS control module, and restarting the car could help clear that.

2. Replace Irresponsive Pedal:

An unresponsive pedal can mean many other things. First, have your mechanic check the brake fluid level and perhaps get the brakes flushed, so there’s no air within the brake lines.

3.  High Pedal Response:

The pedal issues like increased foot effort can mean other things, like worn restraint or a failing brake booster. So make sure to possess your mechanic check everything. If need to know more about brake pads? Discover the perfect Brake Pad Thickness for your ride and, therefore, the right sort of restraint to use.

4. Fixing Faulty Speedometer:

Albeit those lights don’t come on, a faulty speedometer may be a reasonable cause to possess your car verified. So essentially, if you’ve got a clue that your ABS control module could also be going haywire, bring it to a mechanic quickly.

How Much Does Replacement Costs?

It will cost a minimum of about $300 to exchange an ABS control module, but it could cost about $1,500. This total also will have additional fees and taxes added onto it also.

The exact price of the replacement job will significantly depend upon the sort of car you’ve got, how accessible the ABS module is, and therefore the fees charged by the mechanic who works on your vehicle. They’re going to typically charge anywhere from $80 to $110 for the labour costs and anywhere from $220 to $1,090 for the parts costs.


Luckily, it’s not that tough to urge hold of a mechanic, especially with Repair conveniently available seven days every week. So, these are the symptoms of a bad ABS control module. If your ABS control module is acting up, contact the auto shop, and have your ABS issues sorted out immediately.
