What does the Mercedes-Benz PSM malfunction mean?
1 Answers
Mercedes-Benz PSM malfunction indicates a failure in the vehicle stability control system. Causes of the malfunction: The PSM malfunction in a car is generally caused by faults in the PSM system-related programs, faults in the ESP combination sensor circuit, or the ESP sensor itself. When repairing this system, relevant components need to be replaced. Working principle: This system uses multiple sensors to monitor real-time information such as the direction of travel, speed, yaw rate, and lateral acceleration, and then calculates the actual direction of the vehicle. Once the vehicle shows a tendency to oversteer or understeer, the PSM will apply independent braking to the corresponding wheels to prevent the car from deviating from the correct direction of travel.
