Troubleshooting Test Steps    Values    Results    
1. Check for Associated Diagnostic Trouble Codes
A. Establish communication between the Cat® Electronic Technician (ET) and the ECM. Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Download the "Warranty Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
Troubleshoot any associated diagnostic codes listed in Table 2 that are present before continuing with this procedure.
   
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, "Diagnostic Trouble Codes" in order to troubleshoot the associated diagnostic code.
   
2. Check for High Exhaust Temperatures
A. Several factors can cause a calculated high exhaust temperature. Refer to "Troubleshooting, Exhaust Temperature Is High" for further information on calculated high exhaust temperatures.
   
High Exhaust Temperatures
   
Result: The engine is experiencing high exhaust temperatures. Repair the cause of the high exhaust temperature.
Result: The engine is not experiencing high exhaust temperatures.
Proceed to Test Step 3.
   
3. Perform a manual cylinder cutout test.
A. Remove the inlet section (DOC) from the DPF.
B. Use Cat ET to set the value of the "ARD Manual Disable Status" configuration parameter to "Disabled" in order to disable the ARD.
C. Perform a manual cylinder cutout test. Manually cut out each cylinder while 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 the inside of 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" in order 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 the inside of the inlet
