Abstract

A vehicular diagnostic system is described which generally comprises a portable communications control station and a remote data processing station. The control station includes a portable communications controller which is adapted to be connected to a vehicle data terminal capable of supplying parameter data monitored by a vehicle computer and connected to a source of electrical power in the vehicle. The controller also includes the circuitry required to enable the flow of the parameter data through the vehicle data terminal, to compose the data into a predetermined data stream, to record this data stream on magnetic tape, and transmit live or recorded data through a telephone line to the remote data processing station.
