Circuit / System Description
The engine control module (ECM) enables the appropriate fuel injector on the intake stroke for each cylinder. Ignition voltage is supplied directly to the fuel injectors. The ECM controls each fuel injector by grounding the control circuit with a solid state device called a driver. The ECM monitors the status of each driver. Each driver has a feedback voltage circuit which the ECM monitors. The injector control circuits are pulled-up to voltage within the ECM. The ECM can determine if a control circuit is open, shorted to ground or shorted to a voltage by monitoring the feedback voltage.
