For information on the aftertreatment system, Refer to Procedure 011-999 in Section F.
The following procedure contains two main steps: Initial Check
• This is an inspection step to determine the condition of the aftertreatment diesel particulate filter without
removal of the filter. The Initial Check step should be used to determine if the aftertreatment diesel particulate filter has failed due to progressive damage.
Test
• This step of the procedure explains how to perform a stationary regeneration using an electronic service tool
or an OEM-provided stationary regeneration method.
The Test step should only be performed when troubleshooting procedures and/or engine indicator
lamps indicate this is necessary.
If the aftertreatment diesel particulate filter requires replacement, before replacing:
• Troubleshoot and clear all fault codes
• Verify the correct fuel type is being used
• Troubleshoot any oil consumption complaint
• Troubleshoot any coolant consumption complaint
• Inspect the diesel oxidation catalyst. Refer to Procedure 011-049 in Section 11.
The INSITE electronic service tool Aftertreatment Diesel Particulate Filter Stationary Regeneration Test can be
used to:
• Regenerate an aftertreatment diesel particulate filter.
• Recover the aftertreatment diesel oxidation catalyst and aftertreatment diesel particulate filter after coolant
contamination
• Reset the stored soot load in the ECM.
• Check the aftertreatment diesel oxidation catalyst efficiency.
• Check for the presence of the aftertreatment diesel oxidation catalyst
• Check for the correct installation of the aftertreatment temperature sensors.
The INSITE’M electronic service tool Aftertreatment Diesel Particulate Filter Stationary Regeneration Test can be
used to regain functionality of the aftertreatment diesel oxidation catalyst (DOC) and aftertreatment diesel
particulate filter (DPF) after either or both have been exposed to coolant.
The temperatures that are achieved during regeneration are high enough to evaporate the coolant out of both
components and return them to normal operating specifications.
NOTE: It these components are suspected of having coolant contamination, do not perform the Snap
Acceleration Test before performing the regeneration.
