What Does the ABS Warning Light Mean?

ABS stands for the anti-lock braking system. The system is put in place to keep the driver safe by preventing wheel lockup when you apply brakes. It prevents the car from skidding and gives you more control over its steering. A warning light is placed on the dashboard and it illuminates when there is an issue in the anti-lock braking system that requires your attention.

What Reasons Cause ABS Light to Come On?

Here are common reasons that cause the ABS light to come on:

1. Low Levels of Brake Fluid

The brake fluid enables the anti-lock braking system to control the pressure. There is even a reservoir that holds the fluid for the ABS. If there is a leak in the system, the pressure falls, and the reservoir's fluid levels go down. This leak causes the ABS light to come on.

2. The Speed Sensor is Faulty

The wheel hub has a built-in speed sensor that determines the speed by the movement of the wheel. It then transmits the information to the ABS. When one of the wheels moves slowly, the ABS changes the fluid's pressure to enable it to move at the same speed as others. However, if the sensor has a problem, the ABS light will come on.

3. A Bad ABS Module

The ABS module is prone to corrosion. When this happens, it is unable to process the information from the wheel sensors. This event may bring the light on to alert you that it is not working right. The solution to such a problem is to replace the module.

4. Faulty Bulb Check

Some vehicles have onboard computers that check if the dashboard lights are working properly. The system lights up the warning lights, one after the other after some time. However, if the checking system is faulty and gets stuck at the ABS warning light, it may keep the light on even if the ABS has no issues.

5. Worn-out Hydraulic Pump

As said above, the ABS varies pressure, depending on the speed of the wheel. It uses a hydraulic pump to change the pressure on the problematic wheel. Unfortunately, the pump may be damaged and unable to change the pressure. This may cause the ABS light to come on.
