In order to improve the fleet management level and the vehicle maintenance technology level, a remote on-line diagnostic system for vehicles was putted forward and designed in this thesis. This integrated system consists of OBD, GPS, 3G Techniques and GIS platform. By this system, the vehicle running information and the positioning information were collected and sent to the enterprise monitoring center through the 3G network, so the user could acquire the operation status of vehicle in real time. The operation status of vehicle contain vehicle OBD fault information, vehicle speed, engine speed, battery voltage, coolant temperature, date and time, location and path information of the vehicles and so on. This system has a high application value, because it can make the vehicle maintenance staff and fleet manager to get the vehicle’s realtime conditions and location remotely, so that they can give a corresponding maintenance and management methods according to the information.
