Abstract

A method for performing diagnostics on a system of a vehicle includes the steps of receiving a request form an external source, obtaining data relevant to the request, processing the request using the data, and generating a report based at least in part on the processing of the request. The report comprises a diagnostic vector and a life usage vector. The diagnostic vector comprises diagnostic information for the system based at least in part on the processing of the request. The life usage vector comprises information as to usage of the system throughout a life history of the system, based at least in part on the processing of the request.
