[AlainaRose]

The reasons for the ABS brake light to illuminate are: 1. Faulty wheel speed sensor; 2. ABS circuit malfunction; 3. Faulty ABS pump or pressure regulating solenoid valve; 4. ABS computer failure. The solutions for the ABS light illuminating in a car are: 1. Inspect and replace the wheel speed sensor; 2. Replace the ABS pump or pressure regulating solenoid valve; 3. Repair the ABS computer system. The functions of ABS are: 1. To maximize the effectiveness of the brakes, reducing braking time and distance; 2. To effectively prevent vehicle skidding and fishtailing during emergency braking, ensuring good driving stability; 3. To allow steering during emergency braking, providing excellent steering control; 4. To avoid severe friction between the tires and the ground, reducing tire wear.
