Diagnostic Trouble Code for ARD Loss of Combustion    
J1939 Code     Description     Notes    
3474-14     Aftertreatment #1 Loss of Combustion : Special Instruction     This code indicates that the Aftertreatment Regeneration Device (ARD) has stopped generating heat 4 or more times during an active high speed regeneration.
Other diagnostic trouble codes may indicate the cause of the loss of combustion. The codes are listed in the troubleshooting procedure.
The code must be cleared with the "Reset All" button on the active diagnostics screen in the electronic service tool. If an active regeneration is initiated with the forced regeneration switch on the dash, the Electronic Control Module (ECM) clears this code automatically.    
3474-31     Aftertreatment #1 : Loss of Combustion     This code indicates that the Aftertreatment Regeneration Device (ARD) has stopped generating heat 4 or more times during an active regeneration.
Other diagnostic trouble codes may indicate the cause of the loss of combustion. The codes are listed in the troubleshooting procedure.
The code must be cleared with the "Reset All" button on the active diagnostics screen in the electronic service tool. If an active regeneration is initiated with the forced regeneration switch on the dash, the Electronic Control Module (ECM) clears this code automatically.    System OperationThe combustion air system routes pressurized air from the outlet of the high-pressure turbocharger to the ARD. The combustion air is mixed with fuel inside the ARD combustion head. The air/fuel mixture is ignited and the air/fuel mixture is burned in order to increase the temperature of the exhaust gas. The high temperature exhaust gas burns off the soot in the Diesel Particulate Filter (DPF). This process is known as DPF regeneration.The ECM sends a pulse width modulated signal to the combustion air valve. The actuator in the combustion air valve regulates the combustion air to the ARD combustion head.The ECM also sends pulse width modulated signals to the pilot fuel control valve and the main fuel control valve. The fuel control valves regulate the amount of fuel that is injected into the ARD combustion head.If the amount of fuel or air that enters the ARD combustion head is incorrect, combustion may not occur.Test Step 1. Check for Associated Diagnostic Trouble Codes
Establish communication between the electronic service tool and the engine ECM.
Download the following items before performing any troubleshooting or clearing any diagnostic codes:
Warranty Report
Aftertreatment Regeneration Trigger History
Product Status Report with Histograms
Use the electronic service tool to check for active diagnostic codes.
Table 2 lists the diagnostic trouble codes that are associated with "3474-31 Loss Of Combustion" code. Determine if any of the codes in Table 2 are present.

Associated Diagnostic Codes    
J1939 Code     Description     Associated Diagnostic Procedure    
3487-7     Aftertreatment #1 Air Pressure Control : Not Responding Properly     Solenoid Valve - Test    
3480-16     Aftertreatment #1 Fuel Pressure #1 : High - Moderate Severity (2)     ARD Pilot Fuel Pressure Is High    
3480-17     Aftertreatment #1 Fuel Pressure #1 : Low - Least Severe (1)     ARD Pilot Fuel Pressure Is Low    
3480-18     Aftertreatment #1 Fuel Pressure #1 : Low - Moderate Severity (2)     ARD Pilot Fuel Pressure Is Low    
102-18     Engine Intake Manifold #1 Pressure Low (2)     Intake Manifold Air Pressure Is Low    
3556-7     Aftertreatment Fuel Injector #1 : Not Responding Properly     ARD Nozzle Heater - Test    Results:
An associated diagnostic trouble code is not present. - Proceed to Test Step 2.
An associated diagnostic trouble code is present. - Repair: Refer to Troubleshooting, "Diagnostic Trouble Codes" in order to troubleshoot the associated diagnostic code.STOPTest Step 2. Check the Current Flow Through the Heater
Verify that the engine is off. Check the current flow through the heater. Refer to Systems Operation/Testing and Adjusting, "ARD Nozzle Current - Test" for the correct procedure. Expected Result:The current flow is above 7.0 Amps for a 12 VDC system.The current flow is above 3.5 Amps for a 24 VDC system.Results:
The current flow is above the expected amount for the appropriate system voltage . - The current flow is OK. Proceed to Test Step 3.
The current flow is below the expected amount for the appropriate system voltage . - The current flow is low.Repair: Determine the cause of the low current flow. Refer to Troubleshooting, "ARD Nozzle Heater - Test".STOPTest Step 3. Perform a Service RegenerationNote: This test must be performed through the electronic service tool. The electronic service tool enhances the diagnostics during the service test.
If the following codes are active, clear the codes. The ARD will not light if the codes are active.
3703-31 Diesel Particulate Filter Active Regeneration Inhibited Due to Inhibit Switch
3530-31 Aftertreatment #1 Regeneration Manually Disabled
Click the "Disconnect" icon on the electronic service tool in order to disconnect the electronic service tool from the engine.
Turn the keyswitch to the OFF position. Wait for 5 seconds.
Turn the keyswitch to the ON position.
Click the "Connect" icon on the electronic service tool in order to connect the electronic service tool to the engine.
Start the engine. Allow the engine to idle for 3 minutes.
Start a service regeneration by selecting the following menus on the electronic service tool:
"Service"
"Service Procedures"
"Manual Diesel Particulate Filter Regeneration"The electronic service tool will display a "Waiting On Requirements" window. The ECM will automatically elevate the engine speed. The duration of the service regeneration depends on the soot load in the DPF. The ECM will automatically return the engine speed to low idle after the service regeneration is complete.Note: The ECM tests the nozzle for plugging after the service regeneration is complete. An "Aftertreatment Fuel Injector #1 : Not Responding Properly" code will become active if the nozzle is plugged.Expected Result:The service regeneration has been successfully completed.Results:
The service regeneration completes successfully. - STOP
The service regeneration did not complete successfully. - Repair: Check the list of active diagnostic codes. Troubleshoot the code that applies to the failed regeneration. Refer to Test Step 1 for associated codes.
The service regeneration did not complete successfully and there are no
