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.
