Cummins ISB4.5 CM2150 Fault Code: 3145 PID: SID 254 SPN: 4360 FMI: 10 Aftertreatment SCR Intake Temperature Sensor – Abnormal Rate of Change.
Posted by PerDiezel Solutions on
Circuit DescriptionThe SCR catalyst intake temperature sensor is used by the electronic control module (ECM) to monitor the engine exhaust temperature entering the catalyst unit. The ECM monitors the voltage on the signal pin and converts this to a temperature value. Component LocationThe SCR catalyst intake temperature sensor is located in the aftertreatment system. It is located between the turbocharger outlet and the catalyst unit intake in the exhaust system. Conditions for Running the DiagnosticsThe engine and keyswitch must be turned off for period of 8 hours before this diagnostic will run. This diagnostic will only run during engine warm...

Cummins ISB4.5 CM2150 Fault Code: 315 PID: SID 2 SPN: 652 FMI: 6 Injector Solenoid Driver Cylinder 2 Circuit – Current Above Normal or Grounded Circuit.
Posted by PerDiezel 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....
