What are the reasons for the ABS warning light to illuminate in a car?

[GabriellaDella]

Car ABS warning light illuminates due to: 1. Wheel speed sensor failure; 2. ABS circuit failure; 3. ABS pump and pressure regulating solenoid valve failure; 4. ABS computer failure. The ABS light indicates a fault in the ABS system, which may cause the ABS system to stop functioning. The car will behave as if it does not have an ABS system, resulting in reduced braking effectiveness, increased braking distance, and poorer handling performance during braking. When the ABS light comes on, the fault should be promptly addressed. The function of the ABS anti-lock braking system: During car braking, it automatically controls the braking force of the brake system to prevent wheel lock-up, keeping the wheels in a state of rolling and sliding to ensure maximum adhesion between the wheels and the ground, thereby shortening the braking distance.
