5 Signs of ABS Control Module Fault
When your ABS control module is working properly, it gives you the safety you need on the road. When this part starts to fail, it can make you more susceptible to accidents, especially when you have to stop suddenly.
The ABS control module controls the wheel speed and limits the braking pressure on the brake calipers when you brake suddenly to maintain your steering ability.
In this article, we’ll explain the symptoms of a faulty ABS control module, where it fails, how it works, and how much it costs to replace it. First, let’s take a quick look at the signs to look out for.
Symptoms of ABS control module failure
The most common symptom of an ABS control module failure is the ABS warning light on the dashboard coming on. Your wheels may also lock when braking on a slippery road. Another, less common sign is a stiff or unresponsive brake pedal.
These are not all the signs. Here is a detailed list of signs to look out for of an ABS control module failure or malfunction:
1. Wheel Lock (Car Braking Distance)
The ABS control module prevents the wheels from locking up if traction is lost. But because this part is broken, it doesn’t have the accurate information it needs to prevent the wheels from locking up.
If the wheels start to lock when you lose traction, you may have a problem with the ABS control module. You usually only notice the problem when you brake hard. If the wheels continue to lock up, you may have a stuck brake caliper.
2. ABS warning light
All new cars come with an ABS dashboard light to warn you of a problem. If the ABS control module fails, this is one of the reasons the light comes on.
Newer models have an amber light to indicate ABS. However, older models don’t have this special light. They may have a check engine light instead. When the ABS light comes on, the system may not work at all. Even if you can drive without ABS, you shouldn’t. It’s an important security feature designed to protect you.
3. Increased Braking Force
Pressing the brake pedal should now stop the car. However, the amount of force required to stop may increase.
Over time, you may notice that it takes more force to stop your car and press the brake pedal. If you feel like you’re straining your leg every time you stop, you should have the system checked.
4. Brake pedal is unresponsive
You need to make sure that your car stops when you press the brake pedal. However, a faulty ABS control module can make stopping difficult.
First, you’ll notice an increase in braking force, as explained above. Over time, this force will get stronger and you may even experience a complete loss of brake pedal function.
This problem can also occur if your brake fluid level is low, so be sure to perform a full system check. You can flush the brake fluid system to make sure there’s no air in the lines. 5. Inaccurate Speedometer Readings
When the ABS control module fails, it can cause the speedometer to stop working properly. This doesn’t happen often, but it can happen.
The speedometer will either stay at 0 mph or show an incorrect speed. This symptom usually occurs at the same time as the Check Engine Light or ABS Light coming on.
ABS Control Module Function
The ABS (Anti-lock Brake System) control module is an electronic device that functions as a computer. Information from the ABS sensors is processed by the ABS control module. The ECU receives and processes the data to create electronic information that makes sure the system is functioning properly.
If the vehicle loses stability or traction, this system is responsible for processing the next steps to ensure safety. It also helps determine how much pressure needs to be applied to each wheel to bring it to a stop. The control module effectively monitors the frequency of braking and the required brake pressure. It uses information received from sensors that indicate the tire rotation speed to prevent spinning.
ABS Control Module Location
In most vehicles, the ABS control module is located in the engine compartment. However, in some models, it is also located on the driver’s side frame rail. You may need to lift the vehicle to find the ABS control module. It may also be under a plastic panel or cover.
The ABS control module screws onto a magnetic block that has several brake lines attached to it. If you’re unsure, consult your service manual to see where it is located for your make and model of vehicle.
Can the ABS module be serviced?
Yes. ABS control modules can often be repaired, but it’s not easy. Additionally, repairs can be more expensive than a simple replacement. You’ll need to consult with a mechanic or car dealer to determine if your ABS module is repairable or requires replacement.
How long does an ABS module last?
ABS modules are designed to last the life of the vehicle, but like any other component, they can fail at some point. The lifespan of an ABS module can be affected by a variety of factors, including frequency of use, model, and driving conditions. However, in general, you can assume that an ABS module will last at least 10 years.
How do I reset the ABS control module?
In modern vehicles, the only way to reset the ABS control module is with a compatible OBD2 scanner. For older models, it may be enough to disconnect the battery and reconnect it after a few minutes. This ensures that your system is updated frequently and corrects any errors that may have occurred.
Can you drive a car with a bad ABS control module?
Driving with a bad ABS control module can be dangerous and should be avoided if at all possible. Bad ABS control modules can cause a number of problems with your car’s braking system, including reduced braking power, longer stopping distances, and sudden unexpected braking.
