What are the reasons for the constant illumination of the Mercedes anti-skid light?

The reasons for the anti-skid light to illuminate are as follows: 1. Improper operation: Accidentally pressing the ESP off button. 2. Wiring issues: Loose or faulty sensor connectors; short circuits or related fuse blowouts. 3. Software issues: Poor signal transmission due to software problems; ABS pump failure. Additional information: Vehicle anti-skid system: The vehicle anti-skid system has several different names, such as Electronic Stability Program (ESP), Traction Control System (TCS), Anti-Slip Regulation (ASR), Vehicle Dynamic Control (VDC), etc. These are all derivatives of the vehicle anti-skid system. The commonly referred to anti-skid system mainly refers to ESP. The anti-skid light refers to the ESP-OFF light.
I encountered a situation where the anti-skid light stayed on while driving a Mercedes-Benz, usually indicating a minor issue with the ESP system. The most common cause is a dirty or damaged wheel speed sensor, which is located near the wheels and can easily get covered in mud or snow, leading to data errors. Additionally, a faulty ABS control unit can also trigger the warning light, as it manages the entire braking stability. Sometimes, it's just a simple software bug or an incomplete system update, and restarting the car or visiting the dealership for a software update can resolve the issue. There's also the possibility of aging or short-circuited wiring, such as loose wire connections. It's recommended to first check the sensors around the tires yourself, wiping them clean with a cloth. If the light remains on, promptly seek professional repair services to avoid potential hazards, especially since ESP failure can lead to skidding on slippery roads.
As someone with a basic understanding of cars, I believe the main reasons for the continuous illumination of the Mercedes anti-skid warning light include several points: sensor issues, such as damaged wheel speed or steering angle sensors generating incorrect signals; ABS pump or related module failure, which prevents the system from operating stably; it could also be that the system was accidentally manually deactivated, like when there's a button in the car to turn off the ESP function, and a misoperation can trigger the light. Electrical wiring shorts or blown fuses are also potential causes, as they can interrupt data transmission. Additionally, Mercedes software sometimes requires updates, as older versions may have bugs that trigger false alarms. It's best to have technicians check during routine maintenance to prevent issues before they arise. Don't ignore the light when it comes on; addressing it promptly is safer.
