2612-5     3664-6     Cylinder #6 Injector Actuator #2 : Current Below Normal    Background InformationThese engines have Electronic Unit Injectors (EUI) that are electronically controlled. Each injector contains two solenoids. The Engine Control Module (ECM) sends 105 v pulses to each injector solenoid. The pulses are sent at the proper time and at the correct duration for a given engine load and speed.The ECM monitors the current flow through the circuit for each solenoid. If low current flow is detected, a diagnostic code is activated. The ECM continues to try to fire the injector.If high current flow is detected, a diagnostic code is activated. The ECM will disable the solenoid circuit in order to prevent damage from the high current flow. However, the ECM will periodically try to fire the injector. If the short circuit remains, this sequence of events will be repeated
