CONNECTOR- 4444465 - Caterpillar

Which Generate This Code:This diagnostic code is designed to indicate a short circuit (high current) in either the solenoid or the wiring for the electronic unit injector for No. 1 cylinder.The Electronic Control Module (ECM) detects the following conditions:
A high current condition (short circuit) for each of five consecutive attempts to operate
Battery voltage above 9 Volts DC for 2 secondsSystem Response:If equipped, the warning light will come on. The ECM will log the diagnostic code.The engine will have low power and/or rough running.When an injector cutout test is performed, a faulty electronic unit injector will indicate a low reading in comparison with the other electronic unit injectors.An electrical fault can prevent the electronic unit injector from operating. A short circuit in the wiring or the ECM that is unique to one electronic unit injector will prevent that individual electronic unit injector from operating. On four cylinder engines, a short circuit in common wiring within the ECM can prevent the two electronic unit injectors that share that common wiring from operating. On six cylinder engines, a short circuit in common wiring within the ECM can prevent the three electronic unit injectors that share that common wiring from operating.The ECM will continue to attempt to operate the electronic unit injector after the diagnostic code has been logged but a short circuit will prevent the operation of the electronic unit injector.Test Step 1. Perform the following diagnostic procedure: Injector Solenoid Circuit - TestResults:
