What Causes the Anti-Slip System Light to Illuminate?
2 Answers
Reasons for the anti-slip system light illuminating: 1. Accidentally pressing the ESP OFF button; 2. Loose or faulty sensor connectors; 3. Short circuit in wiring or related fuse blown; 4. Software issues causing poor signal transmission; 5. ABS pump failure. Methods to turn off the anti-slip system light: 1. Restart the engine and briefly press the ESP OFF button on the vehicle to check if ESP was accidentally turned off; 2. Visit a 4S shop for inspection, use a specialized diagnostic tool to locate the fault, and after repair, use a decoder to clear the fault code. The warning light will turn off once the ESP is confirmed to be functioning properly.
Last time I drove in the snow, I also encountered this issue with the anti-skid light coming on. Later, my mechanic friend told me it might be because the wheel speed sensor was covered by ice and snow, causing the system to give a false alarm. It could also be that the tire treads are worn unevenly, leading to unbalanced grip and triggering the warning. If this happens right after washing the car, it's likely that the sensor connector got wet and short-circuited. The most troublesome issue is if the ABS pump is faulty—that's expensive to fix. Nowadays, when the light comes on, I usually pull over and restart the engine first. If it stays on, I go check the fault codes. In winter, the biggest thing to watch out for is water splashing onto the chassis and freezing, as it’s the most common cause of such problems.
