1. A vehicle fault diagnosis and prognosis system, comprising: a computing platform on the vehicle configured to receive a fault classifier from a remote server, the computing platform tangibly embodying computer-executable instructions for: evaluating local data sequences received from a vehicle control network; and applying the classifier to the local data sequences, wherein the classifier is configured to determine if the local data sequences define a pattern associated with a particular fault where the classifier is trained by comparing data sequences from a first population of vehicles to repair data from a second population of vehicles.
