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.
3361-5
Aftertreatment #1 DEF Dosing Unit : Current Below Normal This code indicates that there is a problem with the DEF injector and/or the electrical circuit for the DEF injector. Refer to Test Step 4.
3361-6
Aftertreatment #1 DEF Dosing Unit : Current Above Normal This code indicates that there is a problem with the DEF injector and/or the electrical circuit for the DEF injector. Refer to Test Step 4.
3363-5
Aftertreatment #1 DEF Tank Heater : Current Below Normal This code indicates that there is a problem with the coolant diverter valve and/or the electrical circuit for the coolant diverter valve.
3363-6
Aftertreatment #1 DEF Tank Heater : Current Above Normal This code indicates that there is a problem with the coolant diverter valve and/or the electrical circuit for the coolant diverter valve.
3479-5
Aftertreatment #1 Fuel Pressure Control : Current Below Normal This code indicates that there is a problem with the pilot fuel solenoid and/or electrical circuit on the CEM.

4301-5
Aftertreatment #1 Fuel Injector #1 Heater Control : 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.
4301-6
Aftertreatment #1 Fuel Injector #1 Heater Control : 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 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.

Component Controller Electrical Checkout
Coolant Diverter Valve Diesel Exhaust Fluid Controller (DCU) DEF Coolant Diverter Valve Solenoid Override: Turn the keyswitch to the OFF position for 2 minutes. The keyswitch must be off for 2 minutes to allow the DEF pump to purge, to reset the code, and to reset the DCU.
Turn the keyswitch to the ON position.
Initiate the DEF Coolant Diverter Valve Solenoid Override through CAT ET to activate the coolant diverter valve circuit.
DEF Injector Diesel Exhaust Fluid Controller (DCU) DEF Dosing System Verification Test: Initiate the "DEF Dosing System Verification Test" through Cat ET to activate the injector circuit.
