What causes the ABS warning light to illuminate in a car?

[MaxDella]

The reasons for the ABS warning light illuminating in a car are: 1. Wheel speed sensor malfunction; 2. ABS circuit failure; 3. ABS pump or pressure regulating solenoid valve malfunction; 4. ABS computer malfunction. ABS stands for Anti-lock Braking System, which automatically controls the braking force during vehicle braking to prevent wheel lock-up, keeping the wheels in a rolling-sliding state to ensure maximum traction between the tires and the road surface. ABS not only provides the braking function of a conventional braking system but also prevents wheel lock-up, allowing the vehicle to steer while braking, ensuring directional stability and preventing skidding or deviation.
