Five Faulty ABS Control Module Symptoms

 

Making ensuring you can manoeuvre your vehicle in the event of emergency braking is a crucial responsibility of the ABS control module. How to identify a defective ABS control module

You have the security and safety you require when driving with an ABS control module that is functioning properly. If this component starts to malfunction, you become more likely to get in an accident, especially if you need to stop quickly.

To prevent a MOT test failure, check MOT status of your vehicle and have your local mechanic diagnose and fix the illuminated ABS warning light as soon as possible.

In order to preserve your ability to steer, the ABS control module regulates the wheel speeds and restricts the brake pressure to the calliper if you apply the brakes firmly.

In this post, we examine the location and operation of a malfunctioning ABS control module as well as its symptoms. Let's start by quickly going over the warning flags.

A dashboard ABS warning light is the most typical sign of a faulty ABS control module. While braking on slick roads, you can also notice your wheels locking up. A stiff or sluggish brake pedal is another, less prevalent symptom.

If your do start to experience these symptoms, you should immediately look for car garages in Reading online and book your car in with a competent mechanic to fully diagnose and repair the issue.

These are not all the indications;thus, the following is a more thorough list of the most typical signals of a failing ABS control module:

1.      ABS Warning Light - All more recent vehicles are equipped with an ABS dashboard light to alert you of any issues. One reason the light will turn on is if the ABS control module malfunctions. ABS is indicated by an amber light on more recent models. Older vehicles, however, might use the Check Engine Light in place of this specific light instead. The most frequent cause of a MOT test failing is having a dashboard warning light on, according to a web search for "check MOT history. “When the ABS light comes on, the system may completely stop working. Even though the ABS is a necessary safety function designed to safeguard you, you shouldn't drive without it.

2.      Extra Braking Effort - When you press the brake pedal all the way down, you should still stop. The effort required to stop, though, might become more obvious. As time passes, you could realise that applying the brakes to your car requires greater force. If stopping feels like a leg work out every time, you might wish to have the system checked by a qualified mechanic by looking online for garages in Reading.

3.      Unresponsive Brake Pedal - When pressing the brake pedal, you want to be sure that the car will stop. Unreliable ABS control modules, however, might make stopping more challenging. The heightened braking effort mentioned above may at first be apparent. This effort will intensify over time and could even result in you losing all control of the brake pedal. Be cautious to do a thorough system inspection because this problem may also be brought on by low brake fluid levels. If there is any possibility of air in the brake fluid lines, you should think about having the system cleansed.

4.      Locking Wheels - The ABS control module makes sure that when traction is lost, the wheels don't lock up. The information required to prevent the wheels from locking, however, is inaccurate because this component fails. When traction is lost, the ABS control module may be to blame if your wheels start to lock up. Usually, it takes slamming on the brakes to alert you to the issue. Otherwise, if the wheel keeps locking up, it can be a jammed brake calliper.

5.      Incorrect Speedometer Readings - Occasionally, when the ABS control module malfunctions, the speedometer stops functioning normally. While it is unlikely, it is possible that this will occur. The speedometer will either remain at 0 mph or read incorrectly. The check engine or ABS light typically comes on at the same time as this symptom.

How the ABS Control Module Works

The control module for the ABS (anti-lock braking system) is a computer-like electronic device. The ABS control module processes data arriving from the ABS sensors. The ECU uses the processed data to create electronic information, ensuring that the system functions as it should.

This system is in charge of processing the subsequent actions to guarantee safety when the vehicle loses traction or stability. Additionally, it can assist in figuring out how much force should be supplied to each wheel to stop it.

The control module is successfully keeping track of the needed brake pressure and frequency. To prevent any slippage, it makes use of the sensor data indicating how quickly the tyres are turning.

Where is the ABS Control Module?

The majority of cars have an engine compartment where the ABS control module is located. Some versions, nevertheless, also have it on the frame rail on the driver's side.

The vehicle may need to be raised in order to locate the ABS control module. It might also be hidden by plastic covers or panels.

A solenoid block with many brake lines linked to it serves as the mounting point for the ABS control module. If you're unclear, consult the service handbook for your vehicle's make and model to learn where it is.
