1. A wireless communication module for communicating with a remote station and a plurality of motor vehicle control units within a single motor vehicle, the plurality of motor vehicle control units implementing at least two different communication protocols, the wireless communication module comprising:

  • an RF interface including an RF transceiver for communicating with the remote station;

    a processor for communicating with the RF interface, the processor further executing a plurality of diagnostic routines and thereby providing commands to one of the plurality of motor vehicle control units in response to an input received from the RF interface, wherein each of the plurality of diagnostic routines corresponds to a selected motor vehicle control unit; and

    a selectable multiple protocol interface coupled between the plurality of motor vehicle control units and the processor, the selectable multiple protocol interface converting the commands from the processor into a format readable by the selected motor vehicle control unit and converting received diagnostic information into a format readable by the processor, wherein the selectable multiple protocol interface is implemented solely within a field programmable gate array (FPGA).
