What is car ABS? The car ABS meaning is, a short form for Anti-lock Braking System. ABS or ABS brake light is there to keep us safe while driving to prevent wheels from locking up when brake is applied. This is to prevent skidding. What is the ABS light and why is my car’s ABS light on? So, when the light is on, it means that there is a problem with the ABS system. It is an early sign that your brake needs to be checked ASAP! BUT…sometimes it’s not the anti-lock brake system at fault. There are 6 probable causes that this thing happens. You can read more below on why ABS light is on.

1. Dysfunctional ABS Module

   The ABS module can be exposed to corrosion. Before checking everything else, please check the ABS module first. If the module is rusty, then it cannot get information from the wheel speed sensor.

2. Low Brake Fluid

   Why does low brake fluid affect the ABS signal on my car? Brake fluid function is to control brake pressure within the ABS system. So, when there is a leak, the fluid level drops. When this happens, the ABS warning light on the car will turn on.  But, sometimes it is also because of the excessive amount of air in the system.

3. Faulty Speed Sensor

   The latest cars produced are now equipped with a speed sensor to monitor wheel rotation. It sends information to the ABS. If the speed sensor detects one of the tires moving at an abnormal speed, the system will adjust brake pressure of that particular tire and maintain speed of all tires. However, if there is an issue with the speed sensor, it will affect the ability of the ABS and cause the ABS light to ON.

4. Bulb Check

   Sometimes, it may be because your vehicle is performing a bulb check on the dashboard. This is to help the driver to discover if any warning lights are broken. The lights will turn off by themselves after a while. But sometimes, there might be a glitch which makes the ABS light on your car turned on.

5. Worn Hydraulic Pump or Valve

   Why would the hydraulic pump affect the ABS light? So when one of the wheels of your car moves at a different speed, the wheel speed sensor detects this and notifies the ABS. If this happens, the system will activate the hydraulic pump in order for the brake fluid pressure to increase. It allows wheels traction to maintain as they touch the ground.So.. if the hydraulic pump worn out, it will not be able to increase brake fluid pressure and in turns causing the ABS warning light to be ON.

6. Blown Fuse

   Fuses protect electric circuits by breaking them when there’s too much current flowing. Thus, if a fuse is blown, there might be the cause of your ABS light to turn ON.
