P124D CHEVROLET Meaning

The Engine Control Module (ECM) provides voltage to each fuel injector on the high voltage injector supply circuits. The ECM powers each fuel injector by grounding the high voltage fuel injector control circuit. The ECM monitors the status of the high voltage injector supply circuits and the high voltage fuel injector control circuits. When a fuel injector circuit condition is detected by the ECM, the affected fuel injector or injectors are disabled.
