Digital condition data corresponding to a plurality of engine operating conditions of an internal combustion engine are generated and stored in a memory system for visual display to an operator mechanic. Particular data from the memory are converted from a parallel digital format to a serial digital format for transmission to a remote site computer across telephone lines. The remote site computer analyzes the data and returns the diagnostic results for visual display to the operator mechanic.
