In most cases, the ABS light will come on when anything is wrong with the vehicle’s braking system. If you hit the brake pedal and your car doesn’t stop quickly, it could indicate that your brakes are bad.

If the ABS light continues to illuminate, it may indicate a more serious issue, such as a malfunctioning wire harness or wheel speed sensor. However, what does it imply if the ABS light flashes on and off intermittently?

Your vehicle’s braking system may be experiencing a slight issue if your ABS light comes on and then goes out or flashes. It’s possible that you’re driving along and observe the light come on, only for it to go out again a short time later.

A flashing ABS light can also indicate that the module is faulty, which can cause the Electronic Control Unit (ECU) to get incorrect information, which can have a negative impact on other braking components.

As this article explains in great detail, there could be a number of causes for this.

What does ABS flashing mean?

ABS Light Comes On And Off

Sensors are built into the ABS system so that it can keep track of the rotational speed of each wheel as the vehicle moves. In order to keep the automobile stable, the car’s electronic control unit constantly monitors the four wheels and the brake pedal for anomalous signals. For safety reasons, the computer monitor illuminates the ABS warning light when there is no signal from the vehicle’s ABS sensors.

Besides monitoring wheel speed sensors, a blown fuse or low brake fluid levels might cause the computer monitor to switch on the ABS light. When the ABS light “flashes” rather than “stays on” during a drive, it’s referred to as “flashing.” However, it could be a simple symptom of dirt buildup or an indication of broken ABS modules when an ABS light is blinking.

The severity of the problem in the car can be indicated by the flashing of some ABS systems. On the other hand, for minor issues, it will just flash once or twice. Consult your owner’s manual or a trusted professional if you have any questions about what the ABS warning light on your car means.

This might happen after a repair, when technicians forget to reconnect the cables that were previously disconnected. Typically, this problem causes the ABS warning light to come on upon starting a vehicle, but it goes out shortly thereafter when driving. Because of this, you should check the connections of the wires

What causes the ABS light to Go on?

While driving, the most common action of ABS lights is to illuminate and stay illuminated for a long period of time. There are a number of possible causes for this signal, including:

1. Malfunctioning ABS Module

The traction control system in your car and the anti-lock braking system (ABS) both share components that are critical to keeping all four wheels firmly planted and moving freely. A problem with the traction control system could set off your ABS warning light because the two systems share a self-diagnosis system and control module.

Both the software and the control unit can fail at the same time. The electronic module must be thoroughly examined, repaired, or replaced if this is the case.

2. Low Brake Fluid Levels

There are hydraulic components in your car’s braking system. The brakes could malfunction if the fluid inside it is exposed to evaporation or if there is a slow leak. In most cases, a computer monitor in your car will turn on the ABS light as a result of this.

3. Damaged Speed Sensors

If your wheels are moving unnaturally, your traction control system will make the necessary changes on each of your wheels to keep you on your toes. If your ABS is disabled due to faulty speed sensors, you’ll need to get a new one.

What should you do about the ABS light?

When you look at your dashboard and see the ABS light is on, you may be in the middle of driving. That this light signifies a problem with the anti-lock brakes has already been established. To avoid a car accident or system breakdown, it is recommended that you instantly stop your car and inspect the light.

It will be difficult to fix any issues if the ABS unit is faulty. The system error code will be displayed by a scanner if this is the case. Anti-blocking is a problem, according to the information we’ve received.

You can attempt the following if you can’t check for errors:

The ABS light may go out after following the aforementioned instructions, and the anti-lock braking system may be reactivated. There may be more serious problems at play if this does not assist.

The ABS sensor cannot be replaced by the driver. After that, you’ll want to talk to your mechanic about the best course of action.

Your car may require a scan by a scanner to be checked out. A blown fuse in the circuit breaker panel can be the culprit.

The working surface of ABS, which is placed on the wheel, can become clogged up with debris. The ABS indicator will go out after a simple car wash in this circumstance.


Many sensors and warning lights are now standard equipment on newer cars, ensuring that you are always aware of any problems with your vehicle. Depending on the light, you may be reminded to use your seat belt or informed that your car’s oil level is low. In addition to the many other sensors that are necessary, the ABS braking system is perhaps the most critical.

When the ABS light blinks infrequently, it can be a real nuisance. If this happens to you, you should take your vehicle to a mechanic for a thorough examination.

The anti-lock braking system is deactivated if the ABS is engaged, hence harsh braking will result in the wheels locking. In order to avoid instances when emergency braking is required, it is important to quickly identify and fix the issue.
