* Faulty ABS sensor: These sensors monitor wheel speed and are crucial for the ABS to function. A malfunctioning sensor can trigger the light.
* Low brake fluid: Although it might seem unrelated, low brake fluid can also trigger the ABS light.
* Faulty ABS control module (computer): The module controls the entire ABS system. A problem here is a more serious and expensive issue.
* Wiring problems: Damaged or corroded wiring in the ABS system can cause malfunctions.
* Faulty wheel speed sensor ring: This ring is on the wheel hub and is read by the sensor. Damage or corrosion can cause problems.
It's crucial to have the ABS light diagnosed by a mechanic as soon as possible. While your regular brakes will still likely work, the ABS is a safety feature designed to prevent wheel lockup during hard braking. Driving with a malfunctioning ABS reduces your ability to control the vehicle in emergency braking situations. Ignoring the light could lead to a dangerous situation. A mechanic can use a diagnostic tool to pinpoint the exact cause of the problem and recommend the necessary repairs.
