Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 441 PID: PID 168 SPN: 168 FMI: 18 Battery 1 Voltage- Data Valid But Below Normal Operational Range- Moderately Severe Level
Posted by PerDiezel Solutions on
Circuit DescriptionThe engine control module (ECM) receives constant voltage from the batteries through the unswitched battery wires that are connected directly to the positive (+) battery post. The ECM receives switched battery input through the vehicle keyswitch wire when the vehicle keyswitch is turned ON. Component LocationThe ECM is connected to the battery by the OEM harness. This direct link provides a constant power supply for the ECM. The location of the battery will vary with the original equipment manufacturer (OEM). Refer to the OEM service manual. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the keyswitch is in...

Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 4449 PID: SPN: 6773 FMI: 16 Aftertreatment 1 Particulate Sensor Regeneration Status- Data Valid But Above Normal Operating range- Moderately Severe Level
Posted by PerDiezel Solutions on
Circuit DescriptionThe aftertreatment particulate matter sensor is a smart device and communicates with the engine control module (ECM) via the J1939 data link. The aftertreatment particulate matter sensor performs internal diagnostics and reports malfunctions back to the primary ECM using the J1939 data link. The particulate matter sensor is permanently attached to the particulate matter control module. They are serviced as a single component and can not be replaced individually. The aftertreatment particulate matter sensor is used to measure the soot emissions at the outlet of the aftertreatment system. Component LocationThe aftertreatment particulate matter sensor location can vary depending on...
Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 4453 PID: SPN: 5848 FMI: 7 Aftertreatment 1 SCR Intermediate NH3- Mechanical System Not Responding or Out of Adjustment
Posted by PerDiezel Solutions on
Circuit DescriptionThe aftertreatment SCR intermediate NH3 (ammonia) sensor is a smart device that communicates with the engine control module via the J1939 data link. The aftertreatment intermediate NH3 sensor performs its own internal diagnostics and reports malfunctions back to the primary engine control module using the J1939 data link. The aftertreatment intermediate NH3 sensor is used to measure the ammonia in the aftertreatment system. Component LocationThe aftertreatment SCR intermediate NH3 sensor is located in the middle of the aftetreatment SCR catalyst. Conditions for Running the DiagnosticsThis diagnostic has to meet specific engine and aftertreatment conditions to run and complete. Conditions...
Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 4484 PID: SPN: 3667 FMI: 7 Engine Air Shutoff- Mechanical System Not Responding or Out of Adjustment
Posted by PerDiezel Solutions on
Circuit DescriptionThe air shutoff valve is either an original equipment manufacturer (OEM) or Cummins® 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 activates the valve, closing a plate over the intake. Component LocationThe air shutoff valve is either an OEM or Cummins® installed component, and is usually located on the air intake connection. Conditions for Running the DiagnosticsThis diagnostic only runs during an Air Shutoff Valve Test. Conditions...
