What does it mean when the car displays ABS?

When the car displays ABS, it refers to the Anti-lock Braking System. During emergency braking, the system relies on highly sensitive wheel speed sensors installed on each wheel to detect wheel lock-up. The computer then immediately controls the pressure regulator to release pressure from the wheel's brake caliper, allowing the wheel to resume rotation and preventing wheel lock-up. The functions of the ABS Anti-lock Braking System are: 1. To prevent loss of vehicle control, increase braking distance, and enhance vehicle safety; 2. To improve the overall braking performance of the vehicle; 3. To prevent wheel lock-up during braking; 4. To ensure the driver can steer during braking and prevent rear axle skidding.
I remember the ABS light suddenly came on while I was driving last time. It was during a rainy evening, and it really startled me because the ABS is the anti-lock braking system. The light indicates a problem with the system, possibly due to a fault in the sensor or wiring, which could cause the wheels to lock up and skid during braking. At that moment, I immediately slowed down and found a safe place to pull over, avoiding sudden brakes. Fortunately, the regular brakes still worked, otherwise it would have been dangerous on wet roads. Later, I asked a mechanic, and he said common causes include dirty speed sensors on the wheels or blown fuses. He advised checking the circuit codes at a repair shop. Now I know that this light coming on is no small matter—it can affect emergency braking distance. I recommend car owners pay attention to ABS system maintenance to avoid sudden malfunctions during long trips, especially on highways or in rainy conditions, where extra caution is needed.
The ABS light illuminating typically indicates the anti-lock braking system has detected an abnormality, potentially caused by dust accumulation or short circuits in wheel speed sensors, controller module malfunctions, or even aging wiring. When encountering this situation, my first recommendation is not to panic - the basic braking functions usually remain operational, though without ABS assistance. While driving, try to avoid sharp turns or hard braking, and visit a professional repair shop to scan for trouble codes using a diagnostic tool. I've personally experienced false alarms due to contaminated wheel speed sensors. Regular cleaning around the wheels can prevent many issues - while the ABS system is complex, its maintenance is straightforward. Routine checks don't take much time and can significantly improve driving safety.
