Circuit Description
The engine aftertreatment system monitors the soot load in the aftertreatment diesel particulate filter. Under normal operating conditions, the aftertreatment diesel particulate filter is self-cleaning, where soot is converted to carbon dioxide, nitrogen, and water. Under light load operating conditions, it can be necessary to perform a stationary regeneration of the aftertreatment diesel particulate filter. The soot load in the aftertreatment diesel particulate filter is estimated, using the aftertreatment differential pressure sensor and the calculated soot output of the engine.

Component Location
The aftertreatment diesel particulate filter is located in the exhaust system and is installed by the original equipment manufacturer (OEM). Refer to the OEM service manual.

Conditions for Running the Diagnostics
This diagnostic runs continuously when the engine is running and the ECM is requesting active regeneration of the aftertreatment diesel particulate filter.

Conditions for Setting the Fault Codes
The ECM detects that the system is requesting an active regeneration of the aftertreatment diesel particulate filter for an extended period of time.

Action Taken When the Fault Code is Active
The ECM will log the fault code immediately when the diagnostic runs and fails. The ECM will illuminate the Aftertreatment Diesel Particulate Filter lamp immediately when the diagnostic runs and fails.

Conditions for Clearing the Fault Code
To validate the repair, perform INSITE? electronic service tool Aftertreatment Diesel Particulate Filter Regeneration Test.
The fault code status displayed by INSITE? electronic service tool will change to INACTIVE immediately after the diagnostic runs and passes.
The Reset All Faults command in INSITE? electronic service tool can be used to clear active and inactive faults.

Shop Talk
This fault code is an information only fault code indicating that the system was requesting an active regeneration of the aftertreatment system, but was unable to perform an active regeneration.

Possible Cause:
1) ECM calibration
