The invention relates to a vehicle fault detection method and system, a storage medium and electronic equipment, and relates to the technical field of vehicle detection. The method comprises the steps of determining a fault code corresponding to a fault type of a vehicle based on the signal state of a fault type flag bit of the vehicle, wherein one fault type flag bit corresponds to one fault code; recoding all the fault codes of the vehicle into a fault identifier based on a first coding rule; and outputting the fault identifier to enable a detector to determine the fault type of the vehicle according to the fault identifier. The beneficial effects of the invention are that the method achieves the diagnosis of the VCU fault code and the fault level on the premise that a diagnostic instrument is not used, solves a problem that the fault code cannot be reported at the same time, also provides a basis for the remote and quick diagnosis of a fault of a mass production vehicle, and greatly improves the developmen
