Why ABS light comes on and off?

One fairly common problem is the ABS light comes on and then goes back off for seemingly no reason. Most often, this is due to a sensor that is out of balance. As you drive, the sensor may vibrate out of its proper place. When in park, it often resets. Sensors also gather dirt and road grime which can reduce its efficiency over time.

An ABS light on in your car does not necessarily mean that you cannot drive the car. It is an indication that the antilock braking system isn’t working properly. This does not, however, mean that your brakes do not work at all. To avoid skids, the system keeps the wheels from locking while braking.

The light is on means that the ABS system may not work properly. This will be salient if you need to make an emergency stop.  You can still drive it, but with the understanding that ABS braking features may not work.

What does it mean when both ABS and brake light are on?

Sometimes the ABS light and brake light will be on at the same time. This may indicate that there is a failing module in the antilock braking system. Low fluid is another reason that both of these lights may come on at the same time. The wheel speed sensor going on is another potential culprit for this problem.

Both lights on at the same time indicate a more serious problem which you should fix before continuing to drive. You should repair the anti-lock brake system immediately because it related directly to safety.
