What Does the Anti-Lock Brake Warning Light Mean?
The anti-lock brake warning light indicates a potential issue with your vehicle’s Anti-lock Braking System (ABS). This system prevents wheel lockup during hard braking, allowing you to maintain steering control.

Common Causes of an Anti-Lock Brake Warning Light
Several factors can trigger the anti-lock brake warning light. These range from simple issues like low brake fluid or a faulty ABS sensor to more complex problems like a malfunctioning ABS module.
- Low Brake Fluid: The most common culprit. Low brake fluid can disrupt the ABS system’s hydraulic pressure, triggering the warning light.
- Faulty ABS Wheel Speed Sensor: These sensors monitor the speed of each wheel. A damaged or dirty sensor can send incorrect signals to the ABS module, causing the light to illuminate.
- Malfunctioning ABS Module: The ABS module is the brain of the system. If it fails, the entire system can malfunction.
- Damaged Wiring: Wiring issues, such as corroded or damaged wires, can disrupt communication within the ABS system.
