ABSTRACT:
A malfunction diagnosis system is provided to aid a technician or engineer in diagnosing an internal combustion engine. The diagnostic system comprises an electronic control unit that is operatively coupled to a data storage device and to one or more engine sensors. The electronic control unit is configured to collect data from the one or more engine sensors, compare the collected data with predetermined engine parameter values, and store the collected and compared data in the data storage device in various formats. A computer is selectively coupled to the data storage device. The computer program is configured to display specific sets of data and to clearly display any faulty engine parameter values resulting from the collected data comparison.
