How to Deal with the Illuminated ABS Light in a Car?
2 Answers
The methods to handle an illuminated ABS (Anti-lock Braking System) light in a car are: 1. Replace the wheel speed sensor, ABS wiring, ABS pressure control solenoid valve, and ABS computer; 2. Top up the brake fluid; 3. Clean the ABS sensor. The reasons for the ABS light being illuminated include: 1. Faults in the wheel speed sensor, ABS wiring, ABS pressure control solenoid valve, or ABS computer; 2. Insufficient brake fluid; 3. Dirty ABS sensor. The functions of the Anti-lock Braking System 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 good steering control; 4. To avoid severe friction between the tires and the ground, reducing tire wear.
Don't panic when the ABS light comes on! I once encountered this on the highway—immediately eased off the throttle and gently applied the brakes, then pulled into a service area once speed dropped to 60 km/h. In 90% of cases, this light indicates a dirty wheel speed sensor or metal debris interference, especially after driving through mud post-rainfall. If it lights up right after a car wash, there's an 80% chance water entered the sensor connector. Of course, a blown fuse could also be the culprit—specific diagnosis requires an OBD scan. Crucial reminder: Brakes become stiff and lose anti-lock functionality when the light's on; maintain extra following distance in rain. Visit a repair shop ASAP. Unlike my friend who stubbornly drove for three months, only to spend $2,000 replacing the master cylinder later.
