Abstract

A transceiver and additional memory are connected to the microprocessor in a vehicle so that all, or selected portions, of operating data is stored in the memory and periodically transmitted to a remote station. The data is diagnosed at the remote station and, for minor repairs, a fix is transmitted back to the vehicle. The information for a large population of vehicles is used by the manufacturer to determine if a problem is generic to a specific model and to generate repairs and/or model changes.
