What does it mean when the anti-skid system in a Mercedes-Benz stops working?
2 Answers
Mercedes-Benz anti-skid system stops working due to faults in the steering angle sensor, lateral acceleration sensor, or wheel speed sensor. Below is a detailed explanation of the causes: Steering angle sensor malfunction: The acceleration sensor, also known as a gyroscope, controls the position and posture of moving objects. A malfunction causes the ESP to lose position signals, naturally triggering system errors. Lateral acceleration sensor malfunction: A faulty lateral acceleration sensor prevents data transmission to the ECU, making it impossible for the ESP to calculate corresponding values. Wheel speed sensor malfunction: A faulty wheel speed sensor results in the inability to monitor wheel status. In such cases, the ABS warning light will also illuminate.
Over the years of driving a Mercedes-Benz, I've encountered issues with the anti-skid system warning light coming on. This usually happens on wet or uneven roads. Once the system stops functioning, the car's response becomes sluggish, and steering feels like handling a runaway horse, significantly increasing risks. The most common causes include faulty wheel speed sensors, dirty sensors or mud-clogged sensors affecting signal transmission; control module bugs where improper software updates trigger logic errors; blown fuses or short/open circuits interrupting current flow and causing system failure; or issues with stability-related components like the ABS system. Once when I took a high-speed corner, the system shut down - after lengthy inspection, it turned out to be oxidation-induced poor contact in the right front wheel sensor, which was resolved after cleaning. This issue shouldn't be neglected, especially since Mercedes' high-end sensors are precision components. I recommend immediately slowing down and moving away from main traffic lanes, avoiding aggressive driving, and going directly to authorized service centers for professional diagnostic trouble code reading and repair. During regular car washes and maintenance, pay attention to cleaning around wheels to prevent dirt buildup.
