What does the ABS light mean in a car?

[IvanRose]

When the ABS light appears on the car dashboard, it indicates a malfunction in the Anti-lock Braking System. Here are specific details about the ABS system: 1. Function of the ABS system: ABS is the vehicle's Anti-lock Braking System, which is part of the car's active safety systems. When the ABS light comes on, it means the car's computer has detected a fault in the ABS system. 2. Reasons for the ABS light turning on: Under normal driving conditions, the ABS remains dormant. It only activates during emergency braking, such as when braking hard at high speeds. The car's computer assesses this situation and engages the ABS. When the ABS light turns on, it is often due to the wheel speed sensors not functioning properly. The ABS computer cannot detect the driving conditions of each wheel and cannot compare the slip amounts of the wheels, leading to the ABS system's inability to operate correctly.
