What is the solution when the ABS warning light is on?

The solutions for the ABS warning light being on are: 1. Reset the car's computer system by turning off the engine and restarting it after a few minutes; 2. Have a certified technician inspect the vehicle and perform a complete diagnostic of the car's computer to ensure driving safety. The reasons for the ABS warning light being on include: 1. Low battery voltage or a blown fuse; 2. Broken ABS system wires, loose connectors, or improperly secured relay connections; 3. Faulty wheel speed sensors; 4. Malfunctioning hydraulic control unit; 5. Faulty electronic control unit. The principle of the ABS system is to use wheel speed sensors to detect the rotation speed of the wheels. When the braking force is strong enough to lock the wheels, the sensors send a signal to the computer, which then reduces power to the locked wheel to allow it to rotate. Once the wheel starts rotating again, power is restored. If the wheel locks again, this cycle repeats, causing the wheel to rotate in a pulsed braking state. This pulsed braking can occur up to 13 times per second, allowing maximum braking force without causing wheel lock-up, skidding, or loss of control.
My car's ABS light came on before, and it was really nerve-wracking. My first reaction was to slowly pull over to the side of the road—definitely don't force it to keep driving. I tried turning the engine off and restarting it twice, but the light stayed on. I got down to check the sensor positions near all four wheels and found that the small black block by the right front wheel was completely covered in mud. After wiping it clean with a wet cloth and hitting the road again, hey, the light actually went off! If the light stays on after cleaning, you’ll need to check if the wiring connectors are loose. The last resort is to take it to a repair shop to connect to a computer and read the fault codes. Remember, when the light is on, the brakes can become stiff, so leaving enough braking distance in advance is crucial.
