Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 3239 PID: SPN: 4342 FMI: 3 Aftertreatment 1 Diesel Exhaust Fluid Line Heater 2 Circuit- Voltage Above Normal or Shorted to High Source
Posted by PerDiezel Solutions on
Circuit DescriptionThe aftertreatment diesel exhaust fluid line heaters are used to defrost and/or prevent freezing of the diesel exhaust fluid lines. Component LocationThe aftertreatment diesel exhaust fluid line heater 2 is located on the return line between the diesel exhaust fluid dosing unit and diesel exhaust fluid tank. Conditions for Running the DiagnosticsThis diagnostic runs when the keyswitch is in the ON position and line heating is commanded OFF. Conditions for Setting the Fault CodesThe Engine Control Module (ECM) detected the line heater voltage was above a calibratible value and the line heater current was above a calibratible value. Action...
Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 324 PID: SID 3 SPN: 653 FMI: 5 Injector Solenoid Driver Cylinder 3 Circuit- Current Below Normal or Open Circuit

Circuit DescriptionThe injector solenoid valves control fueling quantity and injection timing. The engine control module (ECM) energizes the solenoid by closing a high-side and a low-side switch. Each injector circuit has a dedicated low-side switch that completes the circuit path to ground inside the ECM. Component LocationThe engine harness connects the ECM to the pass-through connector(s) that are located in the rocker housing. Internal injector harnesses are located under the valve cover and connect the injectors to the engine harness at the pass-through connector(s). Conditions for Running the DiagnosticsThis diagnostic runs continuously when the engine is running. Conditions for Setting...

Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 3242 PID: SPN: 3363 FMI: 7 Aftertreatment Diesel Exhaust Fluid Tank Heater- Mechanical System Not Responding or Out of Adjustment
Posted by PerDiezel Solutions on
Circuit DescriptionThe aftertreatment diesel exhaust fluid tank heater keeps the diesel exhaust fluid from freezing in the diesel exhaust fluid tank. The tank heater consists of an electrically powered tank heater control valve which controls the flow of engine coolant to a heating coil inside the diesel exhaust fluid tank. The tank heater control valve opens to allow coolant to flow to the heating coil when heating is commanded, and closes when heating is no longer required. Component LocationThe diesel exhaust fluid tank heater control valve is located near the diesel exhaust fluid tank. Specific location will vary depending on...
Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 3243 PID: SPN: 3060 FMI: 18 Engine Cooling System Monitor- Data valid But Below Normal Operating Range- Moderately Severe Level
Posted by PerDiezel Solutions on
Circuit DescriptionThe coolant temperature sensor is a variable resistor sensor and is used to measure the temperature of the coolant of the engine. The engine control module (ECM) supplies 5 volts to the coolant temperature signal circuit. The ECM monitors the change in voltage caused by changes in the resistance of the sensor to determine the coolant temperature. Component LocationThe engine coolant temperature sensor is located on the thermostat housing. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the engine is running if the coolant temperature was less than 52°C [126°F] when the engine was started. Conditions for Setting...
