Diagnostic Fault Information



Circuit/System Description



The engine control module (ECM) supplies voltage to each fuel injector on the injector high voltage supply circuits. The ECM energizes each fuel



injector by grounding the high voltage control circuit of the fuel injector. The ECM monitors the status of the injector high voltage supply circuits



and the fuel injector high voltage control circuits. When a fuel injector circuit condition is detected by the ECM, the affected fuel injector(s) is



disabled.



Conditions for Running the DTC



* The engine is running.



* The ignition voltage is between 11-18 V.



* The DTCs run continuously when the above conditions are met.
