Cummins ISB4.5 CM2150 Fault Code: 4572 PID: SPN: 3031 FMI: 9 Aftertreatment 1 Diesel Exhaust Fluid Tank Temperature – Abnormal Update Rate
Posted by PerDiezel Solutions on
Circuit DescriptionNormally, switches, accelerators, and other components are connected to the engine control module (ECM) through individual wires. Multiplexing allows those same components to be hard wired to an original equipment manufacturer (OEM) vehicle electronic unit or transmission electronic control unit in the cab. Then, component values and states from components, such as sensors, accelerators, and switches, can be transmitted from the OEM vehicle electronic control unit to the Cummins® engine ECM over the SAE J1939 data link. Messages sent from OEM vehicle electronic control units are received by the Cummins® engine ECM and used for controlling the engine. The...
Cummins ISB4.5 CM2150 Fault Code: 4642 PID: SPN: 97 FMI: 0 Water-in-Fuel Indicator – Data Valid But Above Normal Operating Rage – Moderately Sever Level.

Circuit DescriptionThe water-in-fuel sensor is attached to the fuel filter. The engine control module (ECM) provides a 5 volt reference signal to the water-in-fuel sensor. When the water collected in the fuel filter covers the sensor probes, the water-in-fuel sensor pulls the 5 VDC reference voltage to ground, indicating high water accumulation in the fuel filter. Component LocationThe water-in-fuel sensor is integrated into the bottom of the original equipment manufacturer (OEM) supplied suction fuel filter. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the engine is running. Conditions for Setting the Fault CodesThe ECM detects water in fuel for...
Cummins ISB4.5 CM2150 Fault Code: 465 PID: SID 32 SPN: 1188 FMI: 3 Turbocharger 1 Wastegate Control Circuit – Voltage Above Normal or Shorted to High Source.

Circuit DescriptionThe wastegate actuators are devices used by the ECM to control boost pressure. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the keyswitch is in the ON position. Conditions for Setting the Fault CodesThe turbocharger 1 wastegate control signal is detected to be at system voltage when the voltage is turned off. Action Taken When the Fault Code is ActiveThe ECM illuminates the amber CHECK ENGINE light immediately when the diagnostic runs and fails. Conditions for Clearing the Fault CodeThe ECM will turn off the amber CHECK ENGINE light immediately after the diagnostic runs and passes Possible Causes-A...
Cummins ISB4.5 CM2150 Fault Code: 466 PID: SID 32 SPN: 1188 FMI: 4 Turbocharger 1 Wastegate Control Circuit – Voltage Below Normal or Shorted to Low Source.

Circuit DescriptionThe wastegate actuators are devices used by the ECM to control boost pressure. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the keyswitch is in the ON position. Conditions for Setting the Fault CodesThe turbocharger 1 wastegate control signal is not detected to be system voltage when the signal is turned ON. Action Taken When the Fault Code is ActiveThe ECM illuminates the amber CHECK ENGINE light immediately when the diagnostic runs and fails. Conditions for Clearing the Fault CodeThe ECM will turn off the amber CHECK ENGINE light immediately after the diagnostic runs and passes. Possible Causes-Signal...
Cummins ISB4.5 CM2150 Fault Code: 471 PID: SPN: 98 FMI: 17 Engine Oil Level – Data Valid but Below Normal Operating Range – Least Severe Level.
Posted by PerDiezel Solutions on
Circuit DescriptionAn algorithm in the electronic control module (ECM) calibration monitors engine oil level while the ECM is keyed on and no engine speed is detected. If the engine oil level falls below a certain threshold, the ECM will activate Fault Code 471, as well as the maintenance lamp. The maintenance lamp will flash only during a key-on event. Component LocationThe engine oil level sensor is located on the engine oil dipstick, on the left side of the engine. Conditions for Running the DiagnosticsThis diagnostic runs when the keyswitch is in the ON position and the engine speed is 0...
