ABSTRACT:
A diagnostic tool for simultaneously communicating with a plurality of motor vehicle control units and implements at least two different communication protocols within a single motor vehicle. The diagnostic tool includes a processor and a field programmable gate array. The processor simultaneously executes a plurality of diagnostic routines and thereby provides messages to at least two of the plurality of motor vehicle control units. The field programmable gate array provides a selectable multiple protocol interface to simultaneously accommodating the at least two different communication protocols. The field programmable gate array is coupled between the plurality of motor vehicle control units and the processor. The selectable multiple protocol interface simultaneously converts the messages from the processor into a format readable by the selected motor vehicle control units and simultaneously converting received control unit information into a format readable by the processor.
