Cummins ISB4.5 CM2150 Fault Code: 3383 PID: 411 SPN: 3058 FMI: 0 Engine Exhaust Gas Recirculation System – Data Valid But Above Normal Operating Range – Moderately Severe Level.
Posted by PerDiezel Solutions on
Circuit DescriptionThe engine control module uses the mass air flow sensor reading and calculated charge flow to determine how much exhaust gas is flowing through the EGR connection tube to the intake manifold. The engine control module then compares the calculated EGR flow with the commanded EGR flow in order to control the EGR valve for correct emission levels. Component LocationThe EGR valve is located toward the rear of the engine on the exhaust side. The EGR cross over tube connects the EGR valve to the intake manifold, and crosses over the top of the engine. Conditions for Running the...
Cummins ISB4.5 CM2150 Fault Code: 339 PID: SID 87 SPN: 1267 FMI: 4 Idle Shutdown Vehicle Accessories Relay Driver Circuit – Voltage Below Normal, or Shorted to Low Source.
Posted by PerDiezel Solutions on
Circuit DescriptionThe electronic control module (ECM) Idle Shutdown feature has an optional parameter for a shutdown accessory relay. When this parameter is set to “Installed”, the ECM sends a signal to energize the relay and turn off vehicle accessories during idle shutdown events. The idle shutdown relay return circuit varies by original equipment manufacturer (OEM). The return circuit can be returned to the ECM through the ECM Return (General) or connected directly to ground. Refer to the OEM service manual to determine the grounding configuration. Component LocationThe idle shutdown relay location varies by OEM. Refer to the OEM service manual...
Cummins ISB4.5 CM2150 Fault Code: 3418 PID: SPN: 191 FMI: 19 Transmission Output Shaft Speed – Received Network Data In Error.
Posted by PerDiezel Solutions on
Circuit DescriptionNormally, switches, accelerators, and other components are connected to the engine control module (ECM) directly through individual wires. Multiplexing allows those same components to be hard wired to an original equipment manufacturer (OEM) vehicle electronic control unit (VECU) or transmission electronic control unit (ECU) in the cab. Then component values and states from components such as sensors, accelerators, and switches can be transmitted from the OEM VECU to the Cummins® ECM over the SAE J1939 data link. Messages sent from OEM VECUs or transmission ECUs are received by the Cummins® ECM and used for controlling the engine. The Cummins®...
Cummins ISB4.5 CM2150 Fault Code: 3422 PID: SPN: 4344 FMI: 3 Aftertreatment Diesel Exhaust Fluid Line Heater 3 Circuit – Voltage Above Normal or Shorted to High Source.
Posted by PerDiezel Solutions on
Circuit DescriptionThe aftertreatment diesel exhaust fluid line heater 3 is controlled by the aftertreatment diesel exhaust fluid controller, and receives power through the switch side of the diesel exhaust fluid line heater relay. Component LocationThe aftertreatment diesel exhaust fluid line heater 3 is located on the suction line between the diesel exhaust fluid tank and diesel exhaust fluid dosing unit. Conditions for Running the DiagnosticsThis diagnostic runs when the keyswitch is in the ON position and the heater is commanded on. Conditions for Setting the Fault CodesThe aftertreatment diesel exhaust fluid controller detects that the line heater voltage is above...
