This fault indicates failure of the combustion flame to ignite. When aftertreatment diesel particulate filter (DPF) regeneration is active the aftertreatment control module (ACM) activates the ignition coil, aftertreatment DPF atomization module and air valves in order to create a flame in the aftertreatment DPF combustion chamber. The flame temperature is monitored continually by the ACM. To verify combustion the ACM measures the rise in flame temperature during the first 10 seconds of combustion. If proper combustion during the first 10 seconds of operation is not achieved the fault will be set. Conditions for diagnostic trouble code (DTC):1) Regeneration failed...

During DPF regeneration the Aftertreatment Fuel Pressure Sensor monitors the fuel pressure rise and drop in the Aftertreament Hydrocarbon Dosing Module. During Air Purge the Aftertreatment Fuel Pressure Sensor monitors the air pressure rise and drop in the Aftertreament Hydrocarbon Dosing Module. The Engine Control Module (ECM) uses this input to determine if the system is operating correctly.
