5 Causes of an ABS Light to Come On in Your Car


Modern vehicles have what is known as an anti-lock braking system. The purpose of this system is to keep the driver safe by preventing the wheels from locking up as you apply the brake. That way, you can keep control over the steering and your vehicle won’t skid as a result of the wheels locking up. In addition, there is a warning light on the dashboard which will illuminate if there is any sort of problem with the anti-lock braking system. This is a light that you need to take seriously because it is an early warning sign that your braking system needs to be inspected right away.

5 Common Causes of an ABS Light to Come on

There are many causes which could make an ABS light come on. It doesn’t always mean there is a problem with the anti-lock braking system directly. There could also be a problem with other sensors or components that it communicates with as well.

Below are the top 5 causes of an ABS light coming on.

1. Low Fluid Reservoir

The braking fluid has a lot to do with controlling the braking pressure within an anti-lock braking system. There is a braking fluid reservoir which holds the fluid of the anti-lock braking system. Sometimes there could be a leak from this reservoir which will cause the fluid levels to drop. Either that or excessive amounts of air may exist within the system. Either way, it will certainly cause the ABS warning light to illuminate on the dashboard.

    I had a bent rim for a couple years until I was able to replace it in June 2019. I regularly kept the tire pressure at the required air pressure. And still the ABS light would display on the dash. After replacing the bent rim, the ABS light stopped appearing on the dash. ABS brakes work by measuring the speed and pressure of the tire. If the pressure is inadequate, it will cause the ABS light to appear on the dash.
    In this case the lesson is check tire pressure every two fill ups of gas.
