How to Turn Off ABS Light? Detailed Guides with Extra Tips

The ABS refers to Anti-lock Braking Systems. This element will activate the warning light if there is a problem with your vehicle's brake pedal, alerting you that it can't work anymore. 

So, how to turn off the ABS light after you have detected the issue? You need to inspect the system thoroughly. The code reader can also help you carry the task easier.

This article will give you step-by-step instructions about turning off the anti-lock braking warning light. Let's join us and learn how to do it!

How Does The ABS Mechanism Work?

The ABS maintains a car's directional control and stability during heavy braking.

When one or more tires begin to slide, they lose grip and cause the vehicle to slide irregularly, including entirely sideways.

Many studies have shown that by tracking each wheel's spin rate, the ABS may reduce the probability of a collision by about 18%.

The speed sensor rests adjacent to the wheel and regulates the rotation speed.

The information will then move to the computer module, which analyzes all of the input from the four-wheel sensors.

When the computer detects that one of the wheels is moving slower than the others, it warns the valve to reduce the brake system force.

The computer also commands the pump to maintain this pressure for the wheels to spin again. As a result, if the system is inactive, you may notice the brake pedal vibrate.

Whenever the ABS detects a fault, it will create and store the fault code in its memory, causing the warning light to flash.


The system saves the fault code and turns on the light for every problem

Most of these systems are essentially real-time. As a result, after triggering and repairing the codes, they must clear themselves after a few minutes of working.

Early versions had a lot of features. However, today's systems are more straightforward.

Every wheel has a valve, four-speed sensors, a computer module, and a hydraulic power mechanism. This system makes repairs easier and the cost of the components less expensive.

How to Turn Off ABS Light?

After learning how the system works, you can imagine what prevents it from functioning normally.

In general, there are two approaches to this repair: physically inspect the system and acquire a code reader that can scan ABS codes.

The ALDL connection, like a motor computer controller, may measure the majority of fault codes.

This article will discuss in detail how to physically inspect the system. You will also need a reader for support.

When you can't turn off the ABS light, there must be problems in some parts of your vehicles, such as the fuse, wheel sensor, computer module, and stator ring.

If you want to deactivate the light, check all of these parts. There will be some signals saying that they need replacement.

Step 1: Check the ABS fuse

A fuse is in charge of protecting the anti-lock brake system. However, it may blow as it wears or as a result of an electrical surge.

If the fuse blows again after being replaced, the system may have a fault current, usually the computer or the pump motor.

An ABS fuse often sits in the fuse box beneath the dashboard or under the hood's power system.

Step 2: Test the ABS wheel sensor

The wheel speed sensor controls the wheel rotation. This sensor often cooperates with the wheel stator attached to the bearing hub, CV joint, or brake rotor.

Those sensors will be vulnerable to traffic conditions and vibration, which might cause them to short out. You should conduct a voltmeter test for further information.

Step 3: Replace the ABS wheel speed sensor

The sensor needs replacement if you have scanned the computer and sensor and received these codes: C0035, C0041, C0045, C0040,C0046, C0050, C1222, C1221, C1224, C1223, C1225, C1226, C1228, C1227, C1232, C1233, C1235, C1234. 

Sensor replacement is a simple procedure that you can complete with the help of a floor jack and other basic tools. You can learn how to do it from this video.

Step 4: Replace the ABS computer module

An ABS controller regulates the wheel rotation speed. Unfortunately, it occasionally malfunctions due to electrical breakdown. This computer element stays on the pump motor. 

You must replace the anti-lock brake skid system if it continues to run even after you switch off, making a humming sound.

Step 5: Test the stator ring

The primary purpose of a wheel speed sensor is to regulate the wheel rotation speed. When this ring becomes damaged, the system will stop functioning.

The broken stator ring caused by the missing tooth is still active since it assumes the wheel is going slower. It would help if you physically examined these rings in these situations because there would be no warning signal.

Those rings aren't all in the same place. Some are easily visible, while others may stay inside in separate housing or a bearing hub.


Not all the stator ring is easily visible

When you replace your vehicle's ABS, you should always be cautious when operating it for the first time.

Check for any technical problems or unusual noises that might indicate a problem that remains to be addressed thoroughly.

There is no need to reset the codes in American-built vehicles. However, it would help if you did it with older European and Japanese models.


The warning light can assist you a lot in detecting system problems. However, when you can't turn it off normally, it becomes a new concern.

We have shared a complete guide to tackle the light system malfunctioning with you. Hopefully, you can apply the tips on how to turn off ABS light to your vehicle successfully.
