Supply of power to exhaust gas recirculation electronic drive unit
Engine data recognized by the engine electronic control unit are output-
ted to the CAN bus to enable systems to obtain data that they need for
control. Multifunction Vehicle Control Unit system issues signals to the
engine electronic control unit via the CAN bus to enable it to effect en-
gine control appropriate for type of system control.
