The invention discloses a universal vehicle diagnosis visualized modeling management system. The system adopts a hardware monitor to manage the visualized modeling and diagnosis of a vehicular equipment system, the background database of the monitor is connected with foreground user interface information, a function for fast and accurately building a visualized fault tree is achieved, and manual diagnosis modeling efficiency is increased. The invention further discloses a universal vehicle diagnosis visualized modeling management method. By the method, graphic configuration and visualized display of the feature parameters and the control system of each part in the vehicular equipment system can be achieved, the configured fault tree information can be associated with the element information of the vehicular equipment system through a network, a new fault management function is added without changing hardware, and visualized configuration and display of diagnosis results can be achieved.
