What Causes the Anti-Skid Light to Appear on the Car?
2 Answers
When the anti-skid light comes on, it indicates that the ESP is turned off or malfunctioning. The reasons for the ESP (Electronic Stability Program) light to illuminate include the following aspects: 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. Additional information: 1. If the ESP off button was pressed by mistake, simply turning it back on will eliminate the anti-skid light. However, if the anti-skid light is caused by sensor failure, short circuit in the wiring, blown fuse, poor signal transmission, or ABS pump failure, the vehicle must be taken to a 4S shop for inspection and repair. 2. ESP is primarily used to handle the risk of tailspin loss of control caused by continuous steering during emergency obstacle avoidance. When emergency avoidance is required, ESP intervenes to increase the driving wheel's rotational force; when a tailspin tendency occurs, ESP will apply braking to the opposite wheel to reduce rotation, thereby helping the vehicle follow the driver's steering intentions.
There are many common reasons for the anti-skid light to appear on the car. It could be due to dirty or faulty sensors. For example, if the wheel speed sensor is covered in mud or snow and provides inaccurate data, the light will turn on. Or, the system software might malfunction and automatically report a fault. Additionally, unstable tire pressure or worn-out tires can trigger the warning as the car perceives a risk of skidding. Worse yet, issues with related systems, such as a faulty ABS, can also cause the light to illuminate. When I encounter this situation while driving, I first find a safe place to stop and check, avoiding driving further to prevent danger. You can inspect the tire condition and clean the sensor areas yourself. If the light remains on persistently, it's best to visit a professional shop for diagnosis and repair. Regularly cleaning the sensors during maintenance is a good preventive measure.
