The ABS (Anti-lock Braking System) is a safety feature in today's vehicles that prevents the wheels from locking up during sudden braking, allowing the driver to maintain control and steer the car. When the ABS light on your dashboard comes on, it could indicate a problem with the system, which requires prompt attention from a qualified auto repair shop.

Here's everything you need to know about the ABS system and what to do if the ABS light comes on in your vehicle.

What is the ABS System?

The ABS system is a computer-controlled braking system that uses sensors to monitor the speed of each wheel. If the system detects that one or more wheels are about to lock up, it automatically modulates the brake pressure to prevent skidding and losing control.

What Causes the ABS Light to Come On?

There are several reasons why the ABS light might come on, including:

Failed Wheel Speed Sensor: The wheel speed sensor measures the speed of each wheel and sends the information to the ABS control module. If a sensor fails or malfunctions, the ABS may not function correctly, and the light may come on.

Bad ABS Control Module: The ABS control module is the computer that controls the ABS. If the module fails or malfunctions, the ABS may not work correctly, and the light may come on.

Faulty Brake Light Switch: The brake light switch is a small component that activates the brake lights when you press the brake pedal. If the button fails, the ABS may not work correctly, and the light may come on.

Corroded ABS Rings: The ABS rings are teethed rings mounted on each wheel's hub, which the ABS sensors use to measure wheel speed. If the rings become corroded or damaged, the ABS may not work correctly, and the light may come on.

What to Do When the ABS Light Comes On?

If the ABS light comes on, it is essential to have the vehicle inspected by a qualified auto repair shop as soon as possible. A technician will diagnose the problem using specialized diagnostic tools and perform the necessary repairs to restore the ABS's functionality.

Driving with a faulty ABS is dangerous, especially in slippery conditions or emergency braking situations. Without ABS, the vehicle's wheels could lock up, causing loss of control and potentially leading to an accident.

If the ABS light comes on, have your vehicle inspected by a qualified auto repair shop at Lexbrodies to ensure your safety and that of your passengers.
