Troubleshooting Test Steps Values Results
1. Check for Associated Diagnostic Trouble Codes
A. Establish communication between the electronic service tool and the Electronic Control Module (ECM). Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Table 2 lists the diagnostic trouble codes that are associated with the 3711-31 (E593 (2)) code. Determine if any of the codes in Table 2 are present.
Diagnostic Code
Result: An associated diagnostic trouble code is not present.
Proceed to Test Step 2.
Result: An associated diagnostic trouble code is present.
Repair: Troubleshoot the associated diagnostic code.
2. Check the Current Flow Through the Heater
A. Verify that the engine is off. Use a clamp-on ammeter to check the current flow through the heater.
Between 7.0 A and 14 A for a 12 V system. Or, between 3.5 A and 7 A for a 24 V system
Result: The current flow is OK.
Proceed to Test Step 3.
Result: The current flow is not between 7.0 A and 14 A for a 12 V system. Or, the current flow is not between 3.5 A and 7 A for a 24 V system.
Repair: There may be a problem with the ARD nozzle. Refer to Troubleshooting, "ARD Nozzle Heater - Test".
3. Perform the "ARD Air System Service Test"
A. Reset all active codes and clear all logged codes. Use the electronic service tool to perform an "ARD Air System Service Test" to verify that the problem is resolved.
ARD Air System Service Test
Result: The "ARD Air System Service Test" failed.
Repair: There is a problem with the ARD combustion air system. Refer to Troubleshooting, "ARD Combustion Air - Test".
Result: The "ARD Air System Service Test" passed.
Proceed to Test Step 4.
4. Perform a "Manual DPF Regeneration"
This test must be performed through the electronic service tool. The electronic service tool enhances the diagnostics during the service test.
A. Clear all diagnostic codes.
B. Start the engine. Allow the engine to idle for 3 minutes.
Do not use the operators switch for a stationary DPF regeneration. The service tests provide enhanced diagnostics that are necessary for proper troubleshooting and repair.
C. Start a "Manual DPF Regeneration" in the electronic service tool.
Manual DPF Regeneration
Result: The "Manual DPF Regeneration" completed successfully. There are no additional codes.
Return the unit to service.
Result: The "Manual DPF Regeneration" did not complete successfully.
Repair: Check the list of active diagnostic codes. Troubleshoot the code that applies to the failed regeneration. Refer to Table 2 for associated codes.
Result: The "Manual DPF Regeneration" did not complete successfully and there are no associated codes.
Proceed to Test Step 5.
5. Replace the Fitting that Contains the Filter in the ARD Head
A. Replace fitting (4) that contains the filter in the ARD head.
B. Reset all active codes and clear all logged codes by using the electronic service tool.
C. Perform the "ARD Ignition Test" using the electronic service tool. Refer to System Operation and Testing and Adjusting, "ARD Fuel System - Test".
The ARD Ignition Test cannot be performed if the DPF soot loading is above 80%. When the DPF soot loading is above 80%, the Manual DPF Regeneration must be performed using the electronic service tool.
Filter Fittings
Result: The "ARD Ignition Test" was successful and no codes were logged.
Proceed to Test Step 6.
Result: The "ARD Ignition Test" was not successful.
Proceed to Test Step 7.
6. Perform a "Manual DPF Regeneration"
This test must be performed through the electronic service tool. The electronic service tool enhances the diagnostics during the service test.
A. Clear all diagnostic codes.
B. Start the engine. Allow the engine to idle for 3 minutes.
Do not use the operators switch for a stationary DPF regeneration. The service tests provide enhanced diagnostics that are necessary for proper troubleshooting and repair.
C. Start a "Manual DPF Regeneration" in the electronic service tool.
Manual DPF Regeneration
Result: The "Manual DPF Regeneration" completed successfully. There are no additional codes.
Return the unit to service.
Result: The "Manual DPF Regeneration" did not complete successfully.
Repair: Check the list of active diagnostic codes. Troubleshoot the code that applies to the failed regeneration. Refer to Table 2 for associated codes.
Result: The "Manual DPF Regeneration" did not complete successfully and there are no associated codes.
Proceed to Test Step 7.
7. Replace the ARD Combustion Head
A. Replace the ARD combustion head. Refer to Disassembly and Assembly, "Combustion Head - Remove and Install".
B. Clean the ARD combustion canister.
ARD Combustion Head
Result: The ARD head was replaced.
Proceed to Test Step 8.
8. Perform an ARD Ignition Test
A. Reset all active codes and clear all logged codes. Perform an ARD Ignition Test. Refer to System Operation and Testing and Adjusting, "ARD Fuel System - Test".
The ARD Ignition Test cannot be performed if the DPF soot loading is above 80%. When the DPF soot loading is above 80%, the Manual DPF Regeneration must be performed using the electronic service tool.
ARD Ignition Test
Result: The ARD Ignition Test was successful.
