Aftertreatment DPF Inhibit/Stop Regeneration
Aftertreatment diesel particulate filter (DPF) regeneration, whether the moving or
parked variety, can be stopped if the vehicle is equipped with a DPF Smart switch
(refer to “Aftertreatment DPF Smart Switch”, page 24 for more information). A
regeneration should be stopped only when necessary. To stop a regeneration that is in
progress, press the DPF Smart switch to the DOWN position. The switch will lock
into the DOWN position, and the icon on the bottom of the switch will be illuminated
to indicate regeneration has been stopped.

Figure 16 — Inhibit/Stop Regeneration
CAUTION
When the DPF Smart Switch is pressed
to the DOWN position, the switch
will remain locked in this position
and prevent aftertreatment DPF
regeneration from occurring. Therefore,
it is important to press the switch back
to the middle position and to return it
to standby mode when safe to do so.
Failure to set the switch back to the
MIDDLE position may result in engine
derate, a clogged Aftertreatment Diesel
Particulate Filter (DPF), damage to the
filter and engine shutdown.
CAUTION
Failure to perform a aftertreatment DPF
regeneration in a timely manner may
result in engine derate, a clogged or
damaged DPF, damage to the filter and
engine shutdown.
If the operator stops or inhibits regeneration repeatedly, the DPF will begin to clog
with soot and engine exhaust gas pressure will increase. Eventually the engine will
derate and ultimately shut down. Below is a quick look at the type of regenerations,
conditions of the exhaust aftertreatment system and the action to be taken.
