What are the reasons for the anti-skid fault light to illuminate?

The reasons for the anti-skid fault light to illuminate are: 1. The indicator light stays on, indicating a fault in the vehicle's anti-skid system. 2. Accidentally pressing the ESP OFF button, manually turning off the anti-skid system. 3. Software issues causing poor signal transmission. 4. Fuse blown or circuit shorted. 5. Poor contact or failure at the sensor interface. 6. ABS pump failure. Methods to clear the anti-skid fault light: 1. Restart the engine and briefly press the ESP OFF key to check if the anti-skid system was manually turned off. 2. Visit a 4S shop for inspection, diagnose the cause of the fault, and use a decoder to clear the fault code after repair.
I remember one time when I was driving home, the anti-skid warning light suddenly came on, which gave me quite a scare. As an average car owner, I thought it might be due to a sensor malfunction or a false system alert. The vehicle's anti-skid system primarily uses wheel speed sensors to detect wheel slippage. If these sensors get covered in dirt or fail due to aging, the light may stay on. Wiring issues are also common culprits, such as loose connectors or blown fuses, which can prevent signals from reaching the control module. On the tire front, inconsistent pressure or severe wear can trigger the light too, as the system might misinterpret it as insufficient traction. I immediately pulled over to check the tires and basic wiring, and when everything seemed fine, I headed to the nearest repair shop. They used a diagnostic computer and confirmed that the sensor was dirty—cleaning it turned the light off. Safety-wise, when this light is on, it means the anti-skid function may be disabled, increasing the risk of skidding or accidents on slippery roads. Don't delay; just drive to a professional for inspection.
From my auto repair experience, the traction control light typically indicates sensor system malfunctions. The most common culprit is a faulty wheel speed sensor, often damaged by vibration or clogged with mud/water. Steering angle sensor issues are also frequent - incorrect calibration triggers false alerts. Secondly, software errors in control modules or communication failures (e.g., signal loss between ECU and traction system) can cause persistent illumination. ABS-related problems shouldn't be overlooked either, like blocked valve bodies or pump motor failures. Electrical factors account for many cases too: short circuits, blown fuses, or unstable battery voltage. I recommend using an OBD scanner to read trouble codes and pinpoint the faulty component. Never ignore this warning light - it disables traction assist, significantly increasing risks during rainy highway driving. The safest solution is to have a professional technician address it promptly.
