An ABS (Anti-lock Braking System) control module is a crucial part of the anti-lock braking system. It gives you greater vehicle control by preventing car wheels from locking up when you brake. Since the ABS control module performs an important function, a faulty one is deemed to pose problems with the braking system. Let\u2019s take a closer look at the symptoms of a bad ABS control module, but first, let\u2019s learn how it works. <\/p>\n\n\n\n

How Does an ABS Control Module Work?<\/h2>\n\n\n\n

There are three types of anti-lock braking systems<\/a>, all having similar components. Among these components, one is the ABS control module. The ABS control module rapidly pumps brake fluid<\/a> into the car tyres when the brake pedal is pressed. It controls the small hydraulic pumps that send the pressurised brake fluid into the tyre\u2019s brake lines. This, in turn, slows down the vehicle and maintains complete control over it. <\/p>\n\n\n\n

At low speeds, the power steering pump provides pressure to turn the wheels. The pumping of brake fluid prevents the wheels from locking up, allowing you to steer your car in the direction you wish to go.<\/p>\n\n\n\n

Signs of a Bad ABS Control Module<\/h2>\n\n\n\n

An ABS control module can become faulty for several reasons. A common sign of a bad ABS control module is the activation of one of the car\u2019s warning lights on the dashboard<\/a>, i.e the ABS light. Along with the activation of the ABS light, the other common ABS problems are detailed below.     <\/p>\n\n\n\n

Brakes Locking<\/h3>\n\n\n\n

An ABS control module prevents the wheels from locking. An effective anti-lock braking system<\/a> must have the wheels rotating when braking. They must not lock up, or else you won\u2019t be able to steer or face difficulty in stopping. <\/p>\n\n\n\n

When braking, if the ABS detects that a wheel might lock or one set of brakes is working harder than the other, it rapidly pumps fluid in and out of the brake line via a special valve known as the modulator. The rapid cycling of brake fluid can sometimes cause your vehicle to vibrate, signalling a bad ABS control module. <\/p>\n\n\n\n

Increased braking efforts are required<\/h3>\n\n\n\n

The symptoms of a bad ABS module include spongy brake pedals<\/a> as well. This happens if the brake fluid drops below the required level in the reservoir or due to a faulty ABS control module. <\/p>\n\n\n\n

The ABS control module pumps extra brake fluid into the brakes when required. The faster the brake pedal is pressed, the more fluid is pumped into the brake line until are reach the full brake pressure without wheel locking. <\/p>\n\n\n\n

During this period, if you experience spongy brake pedals, it is because your brakes received an increased brake fluid from the ABS unit. An unresponsive brake pedal must not be taken lightly. <\/p>\n\n\n\n

Check engine light or ABS light activated<\/h3>\n\n\n\n

When an ABS control module fails, either the check engine light<\/a> or the ABS light activates on the dashboard. With the ABS light turned on<\/a>, you might experience a sluggish turning response when applying brakes. This is an indication of low brake fluid levels, a bad ABS control module, or a loose or defective ABS sensor wire.<\/p>\n\n\n\n

Any trouble in the ABS system is often indicated by the activation of the ABS light on the car dashboard<\/figcaption><\/figure>\n\n\n\n

Poor traction control<\/h3>\n\n\n\n

Another symptom of a bad ABS control module is poor traction control. As discussed above, when the ABS modulator detects a potential wheel locking or a set of brakes working harder than the rest, it will start pumping more brake fluid to the affected brakes. <\/p>\n\n\n\n

With a bad ABS control module, there are chances to lose traction because of high brake pressure on one set of wheels than the rest. You must avoid driving with a bad ABS module as it can lead you to dangerous situations with poor traction control<\/a>. <\/p>\n\n\n\n

Inaccurate speedometer readings<\/h3>\n\n\n\n

One of the symptoms of a bad ABS module is incorrect speedometer<\/a> readings. This is because the ABS modulator sends the correct speed signals to the speedometer. While a faulty one will show that you are either going faster or slower than the actual speed. <\/p>\n\n\n\n

It can be dangerous because you might not realise that you are driving too fast than the recommended speed limit. Moreover, you can get fined for driving against the speed limits in the UAE<\/a>.<\/p>\n\n\n\n

FAQs<\/h2>\n\n\n\n

Where is the ABS Control Module located?<\/h3>\n\n\n\n

The ABS control module is most commonly located near the brake pedal assembly, underneath the car dashboard. <\/p>\n\n\n\n

How much does an ABS control module cost in the UAE?<\/h3>\n\n\n\n

An ABS control module in the UAE costs around AED 900 to AED 2000. <\/p>\n\n\n\n

Can you drive with a bad ABS module?<\/h3>\n\n\n\n

A bad ABS control module shows symptoms of locking wheels and unresponsive brake pedals. Such components must remain operational for an optimal driving experience, or else these car brake problems<\/a> can end up in potential car accidents. Therefore, one must avoid driving with a bad ABS module.<\/p>\n\n\n\n

How do I reset my ABS control module?<\/h3>\n\n\n\n

In modern cars, you can reset the ABS control module by using a compatible OBD scanner<\/a>. This will refresh the control module and resolve any errors that occurred.<\/p>\n\n\n\n

This is all about the symptoms of a bad ABS control module. Upon detection of a faulty ABS control module, you must get it replaced immediately. Generally, you can expect an ABS control module to last approximately 10 years. However, if common ABS problems appear early, it is not recommended to get the car inspected and avoid driving it. <\/p>\n\n\n\n

That said, if your car is posing recurrent issues despite regular car maintenance<\/a>, it is better to switch to another one. You can explore these used cars for sale in the UAE<\/a> and have your ideal pick.<\/p>\n\n\n\n
