What Causes the Anti-Skid Light to Stay On?
2 Answers
The reasons why the anti-skid light stays on are: 1. Accidentally pressing the ESP off button; 2. Loose or faulty sensor connectors; 3. Short circuit in the wiring or related fuse blown; 5. Software issues causing poor signal transmission; 6. ABS pump failure. There are two methods to turn off the anti-skid (ESP) light: 1. Restart the engine and briefly press the ESP off button on the vehicle to check if the ESP was accidentally turned off; 2. Visit a 4S shop for inspection, use a specialized fault diagnostic tool to locate the issue, and after repair, use a decoder to clear the fault code to ensure the ESP functions normally, then the warning light will turn off.
The anti-skid light stays on constantly, which I've encountered several times. I believe it's the system detecting a potential fault warning signal. The most common issue is wheel speed sensor problems - those little components get covered in dirt or dust, affecting signal transmission and causing the system to falsely detect skidding. Additionally, the steering angle sensor occasionally miscalibrates, especially after driving on bumpy roads. Electronic control unit failures can also trigger the light, such as bugs in the ABS module. For temporary driving, I recommend maintaining low speed and gentle acceleration because when this light is on, it indicates stability control may be disabled, posing significant risks especially on slippery roads. Use diagnostic tools to scan for trouble codes as soon as possible to accurately identify the cause. Regularly cleaning sensors near the wheels can prevent this issue.
