The wheel speed sensors tell the ABS module how fast each wheel is rotating. Such problems can cause the ABS module to get incorrect information from the wheel speed sensors. These can be caused by faulty wiring, a short circuit, or even a surge of electricity. The ABS module is essentially a computer, and like any computer, it can have electrical issues. This is especially true for the mechanical parts like the pump and the hydraulic valves, which have to do a lot of work every time you brake. Parts of the ABS module can also wear down over time. But what exactly causes an ABS module to go bad? This section will cover the most common reasons why an ABS module might start misbehaving. Reasons Behind a Bad ABS ModuleĮvery machine wears out over time, and the ABS module in your car is no different. However, if the ABS module is not working as it should, it might take longer for your car to come to a complete stop. Increased stopping distancesĪ well-functioning ABS system helps you stop your car in the shortest distance possible, especially in emergencies. This means that your brakes might not respond as quickly as they should when you press the brake pedal. If it’s failing, one of the signs can be reduced brake efficiency. The ABS module plays a key role in ensuring your brakes work effectively. This ABS light is a signal that your braking system needs attention. When the module identifies a problem within the ABS, it turns on this light. This light is connected to the ABS module’s self-diagnostic system. This sensation is a result of the ABS system rapidly activating and deactivating, something it normally does only when you’re trying to brake hard on a slippery surface. If the ABS module is faulty, you might feel a pulsing in the brake pedal. This can be felt when you’re driving and trying to brake. Let’s discuss some of these warning signs.

If the ABS module isn’t working properly, it can exhibit a number of symptoms that we need to watch out for. Pump: After the hydraulic valve reduces the brake pressure, the pump works to restore the pressure so that you maintain control over the brakes.If a wheel is about to lock up, the valve for that wheel is manipulated to reduce the pressure, allowing the wheel to continue rotating. Hydraulic valves: These valves, controlled by the ECU, regulate the brake fluid pressure to each wheel’s brakes.They monitor the rotational speed of each wheel and send this data to the ECU. Wheel speed sensors: These are located at each wheel.It collects data from the wheel speed sensors and decides whether to activate the ABS. Electronic Control Unit (ECU): This is essentially the “brain” of the ABS.The ABS module is composed of several key components: the Electronic Control Unit (ECU), hydraulic valves, wheel speed sensors, and a pump. By doing so, it allows the wheels to keep rotating under hard braking, preventing uncontrolled skidding or wheel lock-up. Located in the engine compartment, this device takes in data from sensors located on your wheels, processes it, and then controls the hydraulic valves in the braking system. The ABS module is a kind of mini-computer responsible for managing the ABS in your car.

In this article, we’ll dive deep into the ABS module, its importance, the signs of a failing module, and how to deal with these problems. ABS light illuminating on the dashboard.

But sometimes, this module can start having problems and affect your car’s braking efficiency.Ĭommon symptoms of a bad ABS module include: This magic box, the ABS module, communicates with the car’s computer, telling it how and when to control the brakes to ensure safe stopping. The ABS (Anti-lock Braking System) module prevents the wheels from locking up or skidding when you apply the brakes, especially on slippery roads.
