What are the reasons for the entire vehicle system failure of the Wuling Hongguang Mini?

[MacBrianna]

If the Wuling Hongguang cannot start or ignite, it may be due to issues with the spark plugs or ignition coils, or problems with the fuel supply system and intake system. In such cases, a professional should use a diagnostic computer to read the fault codes. Below is relevant information about the vehicle's VCU: Function: The VCU collects signals from the accelerator pedal, gear position, brake pedal, etc., to determine the driver's intentions. By monitoring the vehicle's status information, the VCU processes the data and sends control commands to the powertrain and battery system regarding the vehicle's operating status. It also controls the working mode of the onboard auxiliary power system. Additionally, the VCU has functions for diagnosing, protecting, and storing fault information for the entire vehicle system. Design Principle: The VCU hardware adopts standardized core module circuits and VCU-specific circuit designs. The standardized core module circuits can be transplanted and applied to MCUs and BMS, making the platform hardware highly portable and scalable.
