Description
The DPF processes high heat exhaust
gasses, oxidizing harmful emissions
and incinerating soot to ash.
Passive regeneration occurs as part of
normal engine operation.
The InfoCenter does not display an icon
during passive regeneration.
While operating the machine, run the
engine at full-engine speed and high
load when possible to promote DPF
regeneration.
The engine ECU adjusts the exhaust
intake throttle to raise the exhaust
temperature.
The InfoCenter does not display an icon
during assist regeneration.
The InfoCenter displays the
high exhaust temperature icon.
The engine ECU adjusts the exhaust
intake throttle and the injector timing to
raise the exhaust temperature.
Do not shut off the engine or reduce
the engine speed while the reset
regeneration is processing.
