Is the PSM failure in cars serious?

[LaLeo]

The PSM failure in cars is not serious. It is merely a stability management system malfunction. Timely repairs when this failure occurs are sufficient, and it does not affect the daily use of the vehicle. Below is relevant information about the car's PSM: 1. Cause of failure: The PSM failure in cars is generally caused by faults in the PSM system's related programs, issues with the ESP combination sensor wiring, or faults in the ESP sensor itself. Repairing this system requires replacing the relevant components. 2. Working principle: This system uses multiple sensors to monitor real-time information such as driving direction, speed, yaw rate, and lateral acceleration, and then calculates the vehicle's actual driving direction. Once the vehicle shows signs of oversteering or understeering, the PSM will independently brake the corresponding wheels to prevent the car from deviating from the correct driving direction.
