Diagnostic Fault Information
Circuit/System Description
The control module enables the appropriate fuel injector on the intake stroke for each cylinder. Ignition voltage is supplied directly to the fuel
injectors. The control module controls each fuel injector by grounding the control circuit with a solid state device called a driver. The control
module monitors the status of each driver. Each driver has a feedback voltage circuit which the Engine Control Module (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
