Engine
Fuel injectors operating voltage is provided by The Main Relay controlled by ECM. battery voltage passes through the main relay
terminal No.3 to all fuel injector wiring harness connectors terminal No.1. ECM controls Cylinder No.3 fuel injector internal ground
circuit through ECM harness connector EO01 terminal No.64. ECM monitors all fuel injector driver circuits status, if ECM detects
driving circuit status corresponding voltage is incorrect, ECM will set a fuel injector control circuit fault DTC code.
