parked manual aftertreatment diesel particulate filter (DPF) regeneration allowed run, the following normal processes may observed.

• Engine speed (RPM) will ramp around 1,100 RPM and stay there until the DPF regeneration process complete.**

• HEST indicator will turn warn high engine exhaust gas temperature (EGT and will stay during aftertreatment diesel particulate filter (DPF) regeneration.

• DPF Smart switch indicator will shut f during the aftertreatment diesel particulate filter (DPF) regeneration.

• Aftertreatment diesel particulate filter (DPF) regeneration takes between and minutes complete.

• HEST indicator will turn f after aftertreatment diesel particulate filter (DPF) regeneration complete and exhaust temperatures have returned normal.

Aftertreatment DPF Regeneration and O Operation

For aftertreatment diesel particulate filter (DPF) regeneration occur , enough heat must generated the diesel oxidation catalyst (DOC). Heat generated increasing engine speed (RPM) around 1,100 RPM vehicles with a catalyzed aftertratment system. For vehicles that operate a power takeof f and have a DPF , the O must have a maximum rated speed above the minimum RPM listed the tables below that aftertreatment diesel particulate filter (DPF) regeneration (whether automatic manual) can occur when commanded.

Note: For vehicles equipped with a catalyzed DPF , the O must activated a switch that provides both engagement and speed information the vehicle electronic control unit (VECU) when the O engaged. The vehicle operator must use engine speed control set engine speed when the O

Note: Beginning with 198958 and newer the only requirement for aftertreatment diesel particulate filter (DPF) regeneration vehicles equipped with MP7 with non - catalyzed DPF and O less than 650 Altitude and temperature are longer factors for aftertreatment diesel particulate filter (DPF) regeneration and O operation.

• Set parameter Enable Manual Regen During O (JAC) es” “On” using VCADS. This parameter can found the “Misc. V ehicle section Parameter connection Central Systems required set parameter

• Initiate Manual Stationary Regeneration using the DPF smart switch.

• Ensur e the electr onic hand thr ottle (engine speed contr ol) active. The engine speed (RPM) must set greater than the minimum speeds listed DPF Regeneration and O , page the vehicle not configured listed manual stationary aftertreatment diesel particulate filter (DPF) regeneration with the O engaged will not occur When aftertreatment diesel particulate filter (DPF) regeneration does n o t take the DPF will become soot - resulting engine derate and eventual engine

Aftertreatment System Conditioning (Periodic Heat Mode)

During periods extended idling (typically 8 more the aftertreatment system will accumulate unburned hydrocarbons that are released from a diesel Accumulation these hydrocarbons can oxidize the aftertreatment system and can cause damaging temperature spikes and potential hardware failures upon resumed driving during aftertreatment DPF stationary regeneration

Extended idling periods should limited less than hours order protect the aftertreatment However , for customers who idle their vehicles past the hour a periodic heat mode (known Aftertreatment System was developed for the catalyzed aftertreatment

Note: Aftertreatment system conditioning NOT available vehicles equipped with a non - catalyzed aftertreatment system.

Aftertreatment System Conditioning and O Operation
