Vehicle component diagnostic and update system

The present invention relates to the diagnosis and reconfiguration of a vehicle component module such as that associated with a heavy-duty automated transmission by means of a local computer in contact with a central server. A logistic service system includes a programmable vehicle module, a service computer, a central server, a first data link connecting the module to the service computer and a second data link connecting the service computer to the central server. Component information retrieved from the module and stored on the server is used to service the module. The component may be subjected to diagnostics or updated with new parameters.
