Proceed to Test Step 3.
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".
3. Check for High Exhaust Temperatures
A. Several factors can cause a calculated high exhaust temperature. Refer to Troubleshooting, Exhaust Temperature Is High for more information on calculated high exhaust temperatures
High Exhaust Temperatures
Result: The engine is not experiencing high exhaust temperatures.
Proceed to Test Step 4.
Result: The engine is experiencing high exhaust temperatures.
Repair: Repair the cause of the high exhaust temperature.
4. Perform a manual cylinder cutout test.
A. Remove the inlet section (DOC) from the DPF. Refer to Disassembly and Assembly, Inlet Module (Catalyst) - Remove and Install.
B. Use Cat ET 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 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 not found.
Proceed to Test Step 5.
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.
1. Clean 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.
3. Set the value of the "ARD Manual Disable Status" configuration parameter to "Not Disabled" to enable the ARD. Proceed to Test Step 6.
