What Causes the Anti-Skid Light to Stay On?
2 Answers
The main reasons for the anti-skid light staying on are: 1. Accidentally pressing the anti-skid light off button; 2. Loose or faulty sensor connectors; 3. Short circuit in the wiring or related fuse blown; 4. Software issues causing poor signal transmission; 5. ABS pump failure. There are two methods to turn off the anti-skid light: 1. Restart the engine and briefly press the ESP OFF button on the vehicle to check if the anti-skid light was accidentally turned off; 2. Take the vehicle to a 4S shop for inspection, use a specialized fault diagnostic tool to locate the issue, repair it, and then use a decoder to clear the fault code. Once the anti-skid light is confirmed to be working properly, the fault light will turn off.
I personally encountered an issue where the anti-skid light stayed on constantly, usually caused by a dirty or faulty wheel speed sensor. This tends to happen during highway driving or in rainy conditions because the system relies on sensors to monitor wheel rotation. If mud or sand accumulates on the sensor, it can send incorrect data, making the system think the vehicle is about to lose control. Additionally, the ABS system is closely related—if the ABS fuse blows or the module malfunctions, it can also trigger the light. Another possibility is aging wiring or loose connectors. I remember that time I simply rinsed the wheel area at a car wash, and the light turned off. But if the light comes on frequently, it’s best not to delay—get a professional mechanic to read the trouble codes, as this affects driving safety, especially during turns when losing anti-skid protection increases the risk of skidding. Usually, avoiding waterlogged areas when parking can help reduce sensor contamination issues.
