Engine Diesel Engines
• The injectors are directly driven by the PCM. The module has a high-voltage generator
inside, which amplifies the battery voltage into a high voltage of approx. 90 V and stores
it in a capacitor. A control circuit outputs the high voltage to the injectors as a drive
signal.

• All injectors are connected in parallel, i.e. they feature the same PCM terminal for the
positive voltage supply. In case of an open circuit on one injector the PCM cuts off the
power supply for this injector, so that the engine still runs on three cylinders.
