What Causes the Anti-Slip Light to Illuminate?
3 Answers
When the anti-slip system light illuminates, it indicates that the ESP is turned off or malfunctioning. The reasons affecting the illumination of the anti-slip system light include the following aspects: 1. Accidentally pressing the ESP off button; 2. Loose or faulty sensor connectors; 3. Short circuits or blown related fuses; 4. Software issues causing poor signal transmission; 5. ABS pump failure. Additional information: There are two methods to cancel the anti-slip 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 repair, use a decoder to clear the fault code. Once the ESP is confirmed to be working properly, the fault light will turn off.
Last time my anti-skid light came on, which was quite concerning. Later, I learned that it's usually due to tire issues, such as low tire pressure or uneven tire wear affecting traction, causing the system to mistakenly think there's slipping; or the sensors being dirty, covered by mud or snow, leading to false alarms. It can also be triggered by slippery road conditions like rain or snow. There's also the possibility of electrical or computer faults, such as unstable voltage or software bugs. Once the light comes on, avoid accelerating or making sharp turns, slow down, and find a safe place to stop and check tire pressure and sensor cleanliness. If the light stays on, promptly visit a repair shop for diagnosis to avoid increased risks during night driving. Remember, regular maintenance of tires and sensors can prevent this issue.
The traction control light illuminating usually signals that the system has detected abnormal conditions. The most common causes are insufficient tire pressure or uneven tread wear reducing grip, prompting the system to assess slip risk; or ABS speed sensors blocked by debris sending false signals. Road conditions like mud or puddles can also trigger false alerts. Occasionally, onboard system glitches cause erroneous warnings. Initial self-checks: verify tire condition and inflation meet specifications, clear dust/debris near wheel hubs. For persistent illumination, try restarting the vehicle to clear temporary errors, then use diagnostic tools if unresolved. Maintaining system cleanliness serves as crucial prevention.
