Diagnostic Trouble Codes    
CDL Code    J1939 Code    Code Description    Comments    
444-5     677-5     Engine Starter Motor Relay : Current Below Normal     This code indicates there is a problem with the engine starter motor relay and/or the electrical circuit on the ECM.    
444-6     677-6     Engine Starter Motor Relay : Current Above Normal     This code indicates there is a problem with the engine starter motor relay and/or the electrical circuit on the ECM.    
1922-5     2949-5     Engine Intake Valve Actuation System Oil Pressure Control Valve : Current Below Normal     This code indicates that there is a problem with the Engine Intake Valve Actuation System Oil Pressure Control Valve circuit or solenoid.    
1922-6     2949-6     Engine Intake Valve Actuation System Oil Pressure Control Valve : Current Above Normal     This code indicates that there is a problem with the Engine Intake Valve Actuation System Oil Pressure Control Valve circuit or solenoid.    
2232-5     1074-5     Engine Retarder Solenoid : Current Below Normal     This code indicates there is a problem with the engine retarder solenoid and/or electrical circuit on the ECM.    
2232-6     1074-6     Engine Retarder Solenoid : Current Above Normal     This code indicates there is a problem with the engine retarder solenoid and/or electrical circuit on the ECM.    
2461-5     3479-5     ARD Fuel Pressure #1 Control : Current Below Normal     This code indicates there is a problem with the pilot fuel solenoid and/or electrical circuit on the CEM.    
2461-6     3479-6     ARD Fuel Pressure #1 Control : Current Above Normal     This code indicates there is a problem with the pilot fuel solenoid and/or electrical circuit on the CEM.    
3182-5     4301-5     Aftertreatment #1 Fuel Injector #1 Heater : Current Below Normal     There is low current flow between the ECM and the relay for the heating element.
The most likely cause of this code is an open circuit in the wiring between the ECM and the relay. There may be a problem with a connector.    
3182-6     4301-6     Aftertreatment #1 Fuel Injector #1 Heater : Current Above Normal     There is excessive current flow between the ECM and the relay for the heating element. If the high current continues for 10 seconds, the ECM disables the output for the heating element. The power to the ECM must be cycled in order to reset the fault detection circuit.
The most likely cause of this code is a short circuit in the wiring between the ECM and the relay. There may be a problem with a connector.    
3391-5     5425-5     ARD Fuel Pressure #2 Control Actuator : Current Below Normal     This code indicates there is a problem with the main fuel solenoid and/or electrical circuit on the CEM.    
3391-6     5425-6     ARD Fuel Pressure #2 Control Actuator : Current Above Normal     This code indicates there is a problem with the main fuel solenoid and/or electrical circuit on the CEM.    
3405-5     2791-5     EGR Valve Control : Current Below Normal     This code indicates there is an electrical problem with the solenoid valve and/or circuit on the NRS valve actuator    
3405-6     2791-6     EGR Valve Control : Current Above Normal     This code indicates there is an electrical problem with the solenoid valve and/or circuit on the NRS valve actuator.    
3409-5     5276-5     Engine Exhaust Manifold Bank #1 Flow Balance Valve Solenoid : Current Below Normal     This code indicates there is a problem with the exhaust balance valve solenoid and/or electrical circuit.    
3409-6     5276-6     Engine Exhaust Manifold Bank #1 Flow Balance Valve Solenoid : Current Above Normal     This code indicates there is a problem with the exhaust balance valve solenoid and/or electrical circuit.    
3413-5     5424-5     ARD Fuel Flow Diverter Actuator : Current Below Normal     This code indicates there is a problem with the solenoid on the diverter valve and/or the electrical circuit located on the ARD electric fuel pump.    
3413-6     5424-6     ARD Fuel Flow Diverter Actuator : Current Above Normal     This code indicates there is a problem with the solenoid on the diverter valve and/or the electrical circuit located on the ARD electric fuel pump.    
3427-5     5423-5     Aftertreatment Fuel Pump Relay : Current Below Normal     This code indicates there is problem with the relay and/or circuit for the ARD electric fuel pump.    
3427-6     5423-6     Aftertreatment Fuel Pump Relay : Current Above Normal     Indicates there is problem with the relay and/or circuit for the ARD electric fuel pump.
