Cummins ISB4.5 CM2150 Fault Code: 3876 PID: SPN: 3364 FMI: 7 Aftertreatment Diesel Exhaust Fluid Quality – Mechanical System Not Responding or Out of Adjustment.
Posted by Diezel Solutions on
Circuit DescriptionThe DEF quality sensor is a smart device and communicates with the ECM via the J1939 data link. The DEF quality sensor receives power and ground directly from the battery. The DEF quality sensor performs its own internal diagnostics and reports malfunctions back to the primary engine ECM via the J1939 data link. The DEF quality sensor is used to measure the concentration of the DEF in the tank. Component LocationThe DEF sensor is typically mounted in the DEf tank or in-line with the DEF dosing unit supply line. Reference the OEM service manual for a detailed component location...

Cummins ISB4.5 CM2150 Fault Code: 4138 PID: SPN: 1746 FMI: 9 Security Device – Abnormal Update Rate.
Posted by Diezel Solutions on
Circuit DescriptionThe original equipment manufacturer (OEM) security device is an optional device connected to the primary ECM through a J1939 data link network. Messages sent from the security device are received by the Cummins® ECM and are used to control the anti-theft features. The Cummins® ECM and security device must be configured properly so that proper operation of the system will occur Component LocationThe J1939 data link wiring and location of OEM installed J1939 devices varies by OEM. See equipment manufacturer service information for component location. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the keyswitch is in the...
