Method for conducting vehicle diagnostic analyses using distributed structure

The present invention relates to a method for conducting vehicle diagnostic analyses using distributed structure, and more specifically, to a method for accessing information necessary for conducting vehicle diagnostic analyses using a network connection and conducting vehicle diagnostic analyses based on the information obtained therefrom. A method for conducting a vehicle diagnostic analysis comprises the machine-implemented steps of executing a software application for conducting the vehicle diagnostic analysis, receiving signals representative of parameters of a vehicle, accessing a software object over a data transmission network, the software object containing information necessary for conducting the vehicle diagnostic analysis, and determining a vehicle diagnostic state based on the signals representative of the parameters of the vehicle and the information contained in the software object. Since the information necessary for conducting the vehicle diagnostic analysis is distributed in different systems that are connected with a data communication network, an automotive service system can minimize the size of software stored locally and can access most of the information and/or algorithm required for conducting the vehicle diagnostic analysis from a remote system.
