Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 4842 PID: SPN: 3364 FMI: 15 Aftertreatment Diesel Exhaust Fluid Quality- Data Valid But Above Normal Operating Range- Least Severe Level
Posted by PerDiezel Solutions on
Circuit DescriptionThe aftertreatment diesel exhaust fluid quality sensor is a smart device that communicates to the ECM via the J1939 datalink. The aftertreatment diesel exhaust fluid quality sensor performs its own internal diagnostics and reports malfunctions back to the primary engine control module via the J1939 datalink. The aftertreatment diesel exhaust fluid quality sensor is used to measure the concentration of the aftertreatment diesel exhaust fluid in the tank. Component LocationThe aftertreatment diesel exhaust fluid quality sensor is located in the aftertreatment diesel exhaust fluid tank. It may be a combination sensor with the aftertreatement diesel exhaust fluid tank level...
Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 488 PID: PID 105 SPN: 105 FMI: 16 Intake Manifold 1 Temperature- Data Valid But Above Normal Operating Range- Moderately Severe Level
Posted by PerDiezel Solutions on
Circuit DescriptionThe intake manifold air temperature sensor monitors intake manifold air temperature and passes information to the electronic control. The intake manifold 1 temperature sensor is a variable resistor sensor and is used to measure the temperature of the air entering the intake manifold of the engine. The electronic control module (ECM) supplies 5 volts to the intake manifold temperature SIGNAL circuit. The ECM monitors the change in voltage caused by changes in the resistance of the sensor to determine the intake manifold temperature. When the intake air is cold, the sensor or thermistor resistance is high. The ECM signal...
Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 4951 PID: SPN: 6655 FMI: 3 Maintain ECU Power Lamp Circuit- Voltage Above Normal or Shorted to High Source
Posted by PerDiezel Solutions on
Circuit DescriptionThe Engine Control Module (ECM) requires battery power when the keyswitch is ON and for a period of time after the keyswitch is turned OFF. The battery power required lamp is an optional lamp that can be installed to indicate when it is acceptable to remove battery power from the ECM. The lamp will be illuminated when the ECM requires battery power and will extinguish once it is acceptable to remove battery power. Component LocationThe battery power required lamp is an OEM installed component. Refer to the OEM for component location. Conditions for Running the DiagnosticsThis diagnostic runs continuously...

Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 4956 PID: SPN: 6713 FMI: 13 Variable Geometry Turbocharger Actuator Software- Out of Calibration
Posted by PerDiezel Solutions on
Circuit DescriptionThe variable geometry turbocharger (VGT) is electronically activated by the VGT actuator. The VGT actuator is a smart device and receives information via the J1939 data link from the primary engine control module (ECM). The VGT actuator performs its own diagnostics and reports malfunctions back to the primary engine ECM, using the J1939 data link. The ECM then decodes the error message and converts it to a fault code. Component LocationThe VGT actuator is located on the turbocharger bearing housing. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the keyswitch is in the ON position. Conditions for Setting...
