What does it mean when the ABS light comes on in the car?

When the ABS light comes on in the car, it indicates a fault in the ABS system. The reasons for the ABS light illuminating are: 1. Faulty wheel speed sensor; 2. ABS wiring fault; 3. Faulty ABS pump or pressure regulating solenoid valve; 4. Fault in the ABS computer. The inspection methods to take when the ABS light comes on are: 1. Check if the parking brake is fully released; 2. Check if the brake fluid level is within the specified range; 3. Inspect the ABS electronic control unit's wiring plugs and sockets for proper connection; 4. Check the wiring connectors and wires for proper connection or contact; 5. Ensure all relays and fuses are intact and securely plugged in.
Once when I was driving long-distance, the ABS light inexplicably flashed, which made me a bit nervous since this light indicates a fault in the Anti-lock Braking System. Simply put, during hard braking, the wheels might lock up directly, making the vehicle prone to skidding and losing control, especially dangerous in rainy or snowy conditions. That time, I immediately reduced my speed and drove slowly to the service area for a check. The mechanic said common causes are faulty sensors, short circuits in the wiring, or issues with the ABS pump. If left untreated, the braking system can still function but without the anti-lock feature, increasing the risk of accidents. I suggest that as soon as the light comes on, don’t delay—drive to a professional shop to quickly diagnose and fix the issue with a computer scan. Safe driving should always come first. Also, regularly check the wear on your brake pads to prevent problems.
When the ABS light comes on in my car, I always check it myself first. I inspect whether the ABS fuse in the fuse box has blown—it's usually located in a small box under the hood and easy to find with the manual. If that's fine, I then check if the sensors near the wheels are loose or clogged with mud, and try cleaning them. But remember not to tamper with the wiring recklessly; for safety, using an OBD scanner to read the error codes is the most reliable. ABS is a life-saving anti-lock system, and a malfunction means the steering wheel could lock up during emergency braking. After checking, whether the light goes off or not, I immediately drive to the repair shop for a full inspection. Developing a habit of regularly checking the brake system helps reduce such troubles.
The ABS warning light indicates a fault in the vehicle's anti-lock braking system. The braking function still works while driving, but sudden braking may cause skidding. Drive slowly and avoid high-speed emergency stops. Visit a professional repair shop as soon as possible. During regular maintenance, pay attention to cleaning the tire wheel sensors to prevent minor issues. Safety always comes first.
