There are different reasons for why the car ABS light would come on. The main reason is from simply turning on your vehicle. After you put your key in the ignition and turn it on, the computer does a test on the anti-lock braking system to ensure it is functioning normally.
Will low brake fluid cause the ABS light to come on?
One reason your vehicle's ABS light is on is because it may be sensing abnormally low levels of brake fluid. You'll be able to notice if your brake fluid is low by the way your car brakes. The braking may seem soft or spongy. However, if the brake fluid is low, you'll probably see more than just the ABS light come one.
Is ABS warning light serious?
If the warning light comes on while you are driving, it means the ABS is not working properly. This means there is a serious problem with the braking system, and continuing to drive puts yourself and others at risk of a car crash.
What causes ABS to fail?
The most common ABS problems occur when sensors become contaminated with debris or metal shavings. Malfunctions also occur when sensor wiring becomes damaged, resulting in intermittent or no continuity. If you have a malfunction in the ABS, physically check all wiring and the brake sensors first.

How do you know ABS is working?

How do I turn my ABS light off?
Can you drive without ABS?
The ABS system is not critical for the primary function of braking, because the car will stop without the ABS engaging. However, without anti-lock brakes, a car will not have the traction control most drivers expect today.

Can AutoZone check ABS codes?
Unfortunately, the only way to check whether or not the problem is with the ABS is to go and get the codes of your car read. AutoZone can scan your codes as part of our Fix Finder service, or you can do it yourself if you already have a scan tool.
Can ABS lock up your brakes?
The ABS system is specifically designed to prevent any wheel from locking up during heavy braking. A bad ABS module can behave erratically, making your brakes lock up even under normal braking. You might even notice unusual behavior from the brakes, like random clicking noises.
Can ABS be turned off?
Removing a wheel speed sensor will disable ABS—and sometimes, stability control. If your car has a yaw sensor, you can unplug that for results. You can also try simply unplugging the ABS module, though that could adversely affect your car's braking performance.
Can a bad CV joint cause ABS light to come on?
The anti-lock brake system (ABS) may function erratically or illuminate the warning light due a damaged wheel speed sensor. A wheel bearing and/or CV joint with excessive runout can cause the ABS trigger rings to rub against the ABS sensors and damage them.
At what speed does ABS work?
To test how your ABS works, find a straight piece of deserted road. You'll need to be travelling at more than 30kph because many ABS systems shut off as the vehicle gets below around 10-20kph and you'll need enough speed to feel it working. 40-50kph is enough.
How do you activate ABS?
How much does it cost to replace ABS?
An ABS control module replacement can range from $320 to over $1,000. The wide price range isn't really driven by labor cost, which will typically be around $80-$120. It depends on how much the control module costs and how difficult it is to source.
What happens if I unplug my ABS sensor?
On most vehicles, this is not an issue, but on some -- notably pickup trucks -- this can lead to lack of stability under heavy braking as the rear brakes lock up early. If unplugging the sensor makes your problem go away, don't be fooled. Something in the ABS is making that wheel brake by itself, so get it fixed soon.
Will bad ABS light come on wheel bearing?
On many modern cars, a bad wheel bearing will trigger a warning light. The ABS or traction control warnings will often illuminate, since a bad bearing will trip the system to deactivate.
