(2) Operation
• The high-voltage generating device in the EDU converts the battery voltage into high voltage. The ECU sends signals to terminals B through E of the EDU in accordance with the signals from the sensors. Upon receiving these signals, the EDU outputs signals to the injectors from terminals H through K. At this time, terminal F outputs the IJf injection verification signal to the ECU.
