When you drive your car, it is constantly monitoring different sensors to ensure that everything is working as it should. One of the systems that are monitored is the ABS or anti-lock braking system. The ABS monitors your wheels to ensure that they are all turning at around the same speed and uses the brakes to control the vehicle in slippery and bad road conditions.
Why is My ABS Warning Light On?
The ABS system uses sensors located on the wheels to measure their speed. Signals from all four wheels are monitored along with the position of the brake pedal to make sure that the vehicle is controlled and stable. If there are any abnormal signals, or one of the sensors is not sending a signal at all, the ABS warning light will be switched on to inform the driver of the issue.
What is the ABS Warning Light?
The ABS light will usually come on to inform you that the ABS system is getting abnormal signals or is not getting a signal from a certain sensor. However, it can also be turned on for other reasons including a blown fuse or low brake fluid levels.
What Does it Mean When the ABS Warning Light is Flashing?
If you see the ABS light flash and then stay on constantly, this will refer to a trouble code. The number of flashes will help you identify what the issue is that has caused the light to come on. You should refer to your manufacturer’s handbook or information about your make and model of car online to determine what the ABS system is informing you with the flashes.
How Does the ABS Warning Light Work?
The ABS warning light signifies a problem with the sensors on the wheels, brakes, and other parts of the car. Sometimes it can be a simple fix while other times you will need to take your car to a professional. There are a few things you can check at home if you have the right tools. You can remove the wheels so that you can attempt to inspect the sensors and wires for any damage. Double-check to ensure that the fuse for the ABS system has not blown. Bear in mind that if you replace a blown fuse, this is usually a temporary fix and the fuse is likely to blow again in the future.
What are the Common Reasons the ABS Warning Light Will Come On?
When the ABS light shows up on your dashboard, it’s a sign that there is something wrong with your anti-lock braking system. But what exactly is the problem? There are some common reasons why your ABS light might come on. These include:
Low Brake Fluid
The brake fluid is important for controlling the braking pressure within the ABS. The brake fluid reservoir in your car contains the fluid for this system. In some cases, there might be a leak from the reservoir, which will cause the fluid levels to drop. Additionally, there might be a lot of air in the system, which can also lead to low brake fluid.&
Problems With Speed Sensors
Each wheel hub on your car has a built-in sensor to calculate the movement rate of the wheel. The information is then transmitted to the ABS. If one of the wheels is moving too quickly or slowly, the ABS will increase brake fluid pressure to allow the wheel to move normally. Any problems with the speed sensor will be detected by the ABS, which causes the warning light to appear.
ABS Module Problems
After some time, the ABS module might form corrosion. This is a common reason for an ABS light. If there is corrosion on the module it will no longer be able to gather information from the wheel sensors, which ca
