Initiating A Stationary (Parked) Regeneration
NOTE
At starting of the engine, if a stationary
regeneration is required, the engine coolant
temperature must reach 140°F (60°C) before
any stationary regeneration may be initiated
and completed. Permit the engine to idle for a
short while or drive the vehicle until engine
temperature increases sufficiently.
WARNING
Do not initiate a stationary regeneration in a
closed
area like a garage. Stationary
regenerations must be undertaken outdoors only.
WARNING
During stationary regeneration, exhaust
temperature may reach up to 1200°F (650°C) at
the particulate filter. Before initiating stationary
regeneration, make sure that the DPF outlet
diffuser is clear of objects and that no one is
working near the DPF outlet diffuser.
WARNING
Hot surfaces. Keep yourself clear of all hot
Aftertreatment Device components, particularly
during and after active or stationary regeneration.
Hot surfaces can cause serious burns.
NOTE
STATIONARY REGENERATION
This process requires the vehicle to be parked
while the driver or a maintenance technician
initiates the regeneration process.
The DPF Regeneration telltale light illuminates to
notify the driver of the need and urgency of a
manual stationary regeneration.
DPF REGENERATION telltale light
If stationary regeneration is not performed, this
telltale light will blink, indicating that a stationary
regeneration is required immediately. If stationary
regeneration is still not performed, “engine power
derate and shutdown” sequence may occur as
per level 1 to level 4 sequence.
To initiate a stationary regeneration:
l
Park the vehicle in a clear area, vehicle
speed must be 0 mph (0 km/h);
l
Engine must be on normal idle and fully
warmed up (coolant temperature above
140°F/60°C);
l
Apply parking brakes and set the
transmission to neutral (N).
l
Press the DID ENTER button and then get to
the DID Aftertreatment menu. Select sub-
menu Request Parked REGEN and press
ENTER
button to confirm and initiate
regeneration.
The regeneration will begin. Turn off the air
conditioning to reduce engine load. The engine
idling speed will increase to 1600 rpm. Once the
regeneration is completed, the engine speed will
return to normal idle.
Voluntary Interruption Of A Stationary Regen-
eration
It is possible to interrupt a stationary regeneration
at all time. To do so, get to the DID’s
Aftertreatment menu, select Cancel REGEN and
press ENTER button to confirm. You can stop
regeneration simply by releasing the parking
brake. Use this procedure in order to move the
vehicle in a safe area only.
If regeneration is interrupted, it is very important
to reinitiate the regeneration as soon as possible.
CAUTION
If an active regeneration is stopped repeatedly,
the vehicle may need to be taken to a service
facility. The service facility will use a service tool
to manually initiate the regeneration. Moreover,
the interruption of active regeneration should not
be considered as a normal practice. Some
components of the aftertreatment system might
be damaged in the long term.
CAUTION
To void damages to the system components, do
not set the ignition key to the OFF position to
interrupt a stationary regeneration.
