Troubleshooting Test Steps Values Results
1. Check for Associated Diagnostic Trouble Codes
A. Establish communication between the electronic service tool and the ECM. Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Check for any active associated diagnostic codes listed in Table 2.
Associated Codes
Result: An associated diagnostic trouble code is not active or logged.
Proceed to Test Step 2.
Result: An associated code is active or logged.
Repair: Troubleshoot the associated codes before continuing with this procedure.
Refer to Troubleshooting, "Event Codes" to troubleshoot the associated diagnostic code.
2. Check for Boost Leaks
A. Establish communication between the electronic service tool and the ECM. Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Perform an "ARD Air System Service Test".
Service Test
Result: The "ARD Air System Service Test" failed.
There is a problem with the ARD combustion air.
Repair: Refer to Troubleshooting, "ARD Combustion Air - Test".
Result: The "ARD Air System Service Test" was successful.
Proceed to Test Step 3.
3. Perform a Manual Cylinder Cutout Test.
A. Remove the inlet section (DOC) from the DPF.
B. Use the electronic service tool to set the value of the "ARD Manual Disable Status" configuration parameter to "Disabled" to disable the ARD.
C. Perform a manual cylinder cutout test. Manually cut out each cylinder whilst the exhaust is monitored. As each cylinder is cut out, look for a decrease in white smoke.
Faulty Injector
Result: A faulty injector is found.
Repair: Replace any injectors that cause the engine to smoke and run rough when the cylinder is not cut out.
Clean inside the inlet section of the DPF.
Assemble the DPF. The engine must be run with no load at 1400 rpm for at least 15 minutes. If the white smoke continues after 15 minutes, the engine must continue to run until there is no white smoke.
Set the value of the "ARD Manual Disable Status" configuration parameter to "Not Disabled" to enable the ARD. Proceed to Test Step 5.
Result: A faulty injector is not found.
Proceed to Test Step 4.
4. Inspect the DPF
A. Remove the inlet section (DOC) from the DPF.
B. Inspect inside the inlet section and the front face of the DPF. Look for oil and for excessive soot.
C. Inspect the inlet to the Diesel Oxidation Catalyst (DOC). Inspect the inlet of the catalyst and check the catalyst for plugging.
A small amount of soot is a normal condition. Contact the Dealer Solutions Network (DSN) if you suspect that the amount of soot is excessive. Continue with this procedure after you have received guidance from the DSN.
Oil, Excessive Soot or Plugging
Result: Oil is found.
Repair: Perform the following procedure:
1. Inspect the outlet of the turbocharger. Clean the oil from inside the inlet section of the DPF.
2. Assemble the DPF. The engine must be run with no load at 1400 rpm for at least 15 minutes. If the white smoke continues after 15 minutes, the engine must continue to run until there is no white smoke.
Proceed to Test Step 5.
Result: Oil is not found.
Proceed to Test Step 5.
5. 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. Reset all active codes and clear all logged codes.
B. Start a "Manual DPF Regeneration".
Test
Result: The "Manual Diesel Particulate Filter Regeneration" was successful.
Return the engine to service.
Result: The "Manual Diesel Particulate Filter Regeneration" was not successful.
Repair: Troubleshoot any diagnostic codes that are present, if no codes are present, Proceed to Test Step 6.
6. Replace the ARD Head
A. Replace the ARD head.
B. Select the ARD Ignition Test tab. 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.
C. Perform an "ARD Ignition test". to verify proper operation of the Regeneration system.
Test
Result: The ARD Ignition Test was successful.
Return the engine to service.
