Cylinder No.3 Fuel Injector Control Circuit Short to Power Supply
Fuel injector operating voltage is provided by the main relay which is 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 fuel injector ground circuit by ECM
harness connector EN01 terminal No.49. ECM monitors all fuel injector driver circuit status, if ECM detects driving circuit
corresponding voltage is incorrect, ECM will set up a fuel injector control circuit fault DTC code.
