What Causes the Anti-Skid Light to Stay On?
2 Answers
The reasons why the anti-skid light stays on are as follows: It may be due to slippery road conditions causing the ABS to activate, thus triggering the light. Another possibility is a malfunction in the ABS pump, leading to signal transmission errors and false alarms by the computer. Below is an introduction to the anti-skid light: 1. Meaning: The anti-skid light is a general term for systems or programs designed to enhance vehicle handling performance while effectively preventing loss of control when the car reaches its dynamic limits. Electronic stability programs can improve vehicle safety and handling. 2. 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 ESP was accidentally turned off; (2) Take the vehicle to a 4S shop for inspection, use a specialized fault diagnostic tool to locate the issue, and after repairs, use a decoder to clear the fault codes. Once the ESP is confirmed to be functioning properly, the fault light will turn off.
As a long-time car mechanic, I've found that when the anti-skid light stays on, it's mostly due to some issues with the sensors, such as the wheel speed sensor being dusty or damaged. These sensors are installed near the wheels and are prone to mud and water erosion, which can cause false signals. Another possibility is accidentally turning off the system switch—some cars have a button under the steering wheel that can directly disable the anti-skid function. If you press it by mistake, the light will stay on. More serious issues could be aging or short-circuited wiring, or a computer fault in the car causing the system to misjudge. I recommend first trying to find and reset that switch yourself. If that doesn’t work, check if the sensors around the wheels are clean. If the light stays on while driving, the anti-skid system won’t function, making the car prone to skidding on wet or slippery roads, which could lead to accidents. It’s best to take it to a shop quickly and let a professional inspect it with specialized equipment. Don’t try to dismantle things yourself to save trouble—you might end up causing more damage.
