What does the ABS indicator light on the car dashboard mean?

The ABS indicator light on the car dashboard refers to the Anti-lock Braking System of the vehicle. When the ABS light is on, it indicates a fault in the ABS system, which continuously monitors the car's wheels to ensure they turn at exactly the same speed. During braking, the ABS system controls the braking force using the brakes, keeping the wheels in a state of rolling and sliding without locking up. This ensures maximum traction between the wheels and the road surface, preventing the car from skidding. If there is a fault in the ABS system, the following steps should be taken: 1. Check the power circuit of the ABS regulator to eliminate any power circuit faults; 2. Check if the battery voltage is too low. If the battery is not at 12V, the battery needs to be replaced or the charging system repaired.
When the ABS light on your car's dashboard comes on, it's no small matter. I remember last year during a long drive when the light came on, I immediately pulled over to check the manual. ABS stands for Anti-lock Braking System, designed to prevent wheel lock-up during hard braking, helping you maintain control of the vehicle. The illuminated indicator means the system's self-check failed or there's a malfunction—common issues include dirty sensors, loose wiring, or a faulty control module. Driving without ABS can cause skidding, especially in rain or snow, which is highly dangerous. Later, at the repair shop, I found that dust buildup on the left front wheel sensor caused inaccurate readings; cleaning it fixed the issue. My advice: if the light comes on, don't push it—slow down and get it checked. Also, when washing your car, keep the wheel areas clean to avoid buildup.
