Abstract: A vehicle diagnostic system including a processor, a user interface including a display device and an input device both coupled to the processor for interactive control thereof and thereby, and a local storage library connected to the processor for storing at least one application to be performed on a vehicle. The processor is programmed to request vehicle identification information from a user through the display device, create a particular configuration identifier containing the vehicle identification information entered by the user through the input device, store the particular configuration identifier in the local storage library, retrieve at least one application from the library as the application is selected by the user through the input device, and provide the particular configuration identifier to the application.

Abstract: An integrated diagnostic system includes interface connectors to connect to a plurality of instruments/instrument modules, including engine analyzers, gas analyzers, oscilloscopes, scanners, network connections, and/or other desired peripheral modules. These modules advantageously interface to the system through diverse parts, connections and with various protocols. The system may connect to a network, wired or wireless, for interfacing among processors and modules, and with an internet connection for interaction with remote resources including databases and expert systems.
