(1) General Description
• An EDU is provided to enable high-speed actuation of the injectors. The EDU has a high-voltage generation device
(DC/DC converter) and supplies high voltage to the injectors to actuate the injectors at high speed.
(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.

1.How to test an EDU?
2.Why caused the injectors to have no power supply
(current).
My engine diagnosis says shows EDU.My vehicle engine stops even when I pedal the accelerator. The engine keeps on stopping running. Is it the EDU unit that needs changing or something else?
Thank you
