Abstract

See full text

A multi-stage diagnostic system and related method which seeks diagnostic information from a secondary information source when a first information source does not yield sufficient data for producing a diagnostic result. In particular, diagnostic process includes a first stage of communicating with an onboard vehicle computer to retrieve diagnostic trouble codes therefrom. If diagnostic trouble codes are received from the onboard computer, the diagnostic trouble codes are used to produce a diagnostic result. On the other hand, if no diagnostic trouble codes are retrieved from the onboard computer, the diagnostic process proceeds to a second stage wherein symptomatic diagnostic information is solicited from the user. A series of symptomatic questions may be presented to the user on a smartphone.
