The reasons for the continuous illumination of the vehicle anti-skid indicator light are: 1. Accidentally pressing the ESP 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. When the anti-skid system light is on, it indicates that the ESP is turned off or malfunctioning. The ESP system is a chassis braking technology developed based on the anti-lock braking system (ABS), primarily consisting of a control unit, steering sensor, wheel speed sensor, slip angle sensor, and lateral acceleration sensor. ESP enables automatic safety control of the vehicle, effectively improving driving stability and safety under dynamic conditions such as braking, acceleration, and steering.
When I first started driving, I encountered the issue of the anti-skid light staying on constantly, which really scared me. Later, I figured out it might be a faulty wheel speed sensor—that little thing detects wheel speed inaccurately, causing the system to throw false alarms. It could also be a problem with the brake system, such as worn brake pads or an issue with the ABS module, preventing the anti-skid function from activating. You need to be especially careful when driving in the rain—if this light is on, it means the vehicle is unstable and prone to skidding when turning. I recommend going to a 4S shop or using a diagnostic tool to check it out as soon as possible. Spending a little money to replace the sensor will solve the problem. Safety comes first—don’t ignore it.
