Wear goggles, gloves, protective clothing, and a National Institute for Occupational Safety and Health (NIOSH) approved P95 or N95 half-face respirator when handling a used Diesel Particulate Filter or Catalytic Converter Muffler. Failure to do so could result in personal injury.
The muffler, catalytic converter/muffler, and diesel particulate filter will become extremely hot during engine operation. A hot muffler, catalytic converter/muffler and diesel particulate filter can cause serious burns. Allow adequate cooling time before working on or near the muffler, catalytic converter/muffler and diesel particulate filter.
The wall flow Diesel Particulate Filters (DPF) require periodic removal of ash that accumulates from engine oil.Cleaning Procedure
Follow this cleaning procedure for removal of the ash from the wall flow DPF. Refer to Operation and Maintenance Manual for the intervals of service hours for cleaning of the wall flow DPF.
Connect the engine to the electronic service tool before the wall flow DPF is removed from the engine. Once the engine is connected to the electronic service tool, then perform an ash service test. This test is a manual regeneration. The test could take an hour.Note: Allow the wall flow DPF to cool until the wall flow DPF can be safely removed.
Remove the wall flow DPF from the Clean Emissions Module (CEM). Refer to Disassembly and Assembly for the correct procedure.Note: Identify all engine fault codes if black soot is discovered on the outlet side of the center section on the wall flow DPF. Refer to Troubleshooting for problem identification and the disposition of the wall flow DPF.
Clean the wall flow DPF. Refer to Special Instruction, NEHS1109, "Compact DPF Cleaner" for the cleaning procedure.
Reinstall the wall flow DPF onto the Clean Emissions Module (CEM). Refer to Disassembly and Assembly for the correct procedure.Reset the Engine Ash Model
The engine ash model must be reset whenever the filter is cleaned or replaced. Resetting the ash model places the wall flow DPF volume back to the "Clean State". The resetting will allow the regeneration of the wall flow DPF to function properly.
Use the electronic service tool to access the following menus:
Service
Configuration
Component Replacement Resets
Ash Service Calibration
Choose the correct replacement type of diesel particulate filter in the menu that appears. The types of replacements for the diesel particulate filter are the following:
"New filter replacement"
"Remanufactured filter replacement"
"Filter cleaned and reapplied"Note: If a new filter or a remanufactured filter is used, the new serial number must be programmed into the electronic service tool.Note: For the "Filter cleaned and reapplied" option, use the electronic service tool to perform the "DPF Ash Cleaning" reset.Note: For the "New filter replacement" option, use the electronic service tool to perform the "DPF Replacement Reset".
The electronic service tool will display "Ash Service Calibration Successful" when the calibration has been completed.
