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) Lost flame...

This diagnostic trouble code (DTC) indicates malfunction at the aftertreatment diesel particulate filter (DPF) flame temperature sensor. This aftertreatment DPF flame temperature sensor is used to measure engine exhaust gas temperature (EGT) within the flame region of the aftertreatment DPF during aftertreatment DPF regeneration. The aftertreatment control module (ACM) monitors this temperature to detect the existence of the flame. Diagnostic trouble codes (DTCs) may result if the system is unable to light the flame or if there are multiple flame losses. Aftertreamemt DPF regeneration will be prevented until the system is sufficiently warmed-up for the specified duration. Conditions for diagnostic...

The function identifies and indicates malfunction of the aftertreatment diesel particulate filter (DPF) by analyzing the pressure drop over the aftertreatment DPF. This is done by making a check for deviation between sensor value and a model pressure drop. In some extreme cases the engine will derate. Conditions for diagnostic trouble code (DTC):1) High differential pressure across the filter (> 35 kPa (5 psi / 10.3 in-Hg)) Observable symptoms1) Low Power2) Medium to high derate Probable cause1) Excessive smoke from the engine2) Aftertreatment diesel particulate filter (DPF) is loaded with soot3) Aftertreatment diesel particulate filter (DPF) is loaded with ash4)...
