Cummins ISB4.5 CM2150 Fault Code: 312 PID: SID 274 SPN: 655 FMI: 6 Injector Solenoid Driver Cylinder 5 Circuit – Current Above Normal or Grounded Circuit.
Posted by Diezel Solutions on
Circuit DescriptionThe injector solenoid valves are actuated by the electronic control module (ECM) to control fuel metering and timing. Each injector solenoid is connected to the ECM by a supply and a return wire. An electrical pulse is sent to the injector from the ECM on the supply wire and returns to the ECM on the return wire after actuating the solenoid. Each solenoid valve is normally open, and it is only closed by an electrical pulse from the ECM during fuel injection and metering. Component LocationThe ISM has an internal actuator harness that connects to the external engine harness....

Cummins ISB4.5 CM2150 Fault Code: 3139 PID: SPN: 3667 FMI: 3 Engine Air Shutoff Circuit – Voltage Above Normal or Shorted to High Source.
Posted by Diezel Solutions on
Circuit DescriptionThe engine air shutoff valve is an original equipment manufacturer (OEM) installed component that shuts off the flow of air into the intake of the engine in order to prevent an engine overspeed condition. When activated, the engine control module (ECM) supplies 12 VDC to the air shutoff solenoid. This solenoid then supplies air to the air shutoff valve and activates the valve, closing a plate over the intake. Component LocationThe engine air shutoff valve location can vary, depending on the OEM. See equipment manufacturer service information. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the keyswitch is...
