Volvo D13F - Aftertreatment System Maintenance

Volvo Engines 9
If the regeneration process is not delayed,
the regeneration process starts, the DPF
Regeneration Required icon turns off and the
High Exhaust System Temperature (HEST)
icon may illuminate.
Note: It is important to enable regeneration
as soon as possible to avoid engine
problems. Long-term engine operation with
regeneration disabled will result in a loss of
engine performance including horsepower,
torque and speed derates. Also, the DPF
filter will become overloaded with soot and
require service.
The regeneration process can be stopped
at any time by turning the ignition key to
OFF, or by pressing the bottom of the Smart
switch.
Regeneration cannot be initiated if it is not
required. The following conditions must be
met for parked regeneration:
•
Parking brake is on and transmission
in neutral
•
Battery charge is greater than 10 volts
•
Engine is running
•
Accelerator pedal is released
If the DPF Regeneration Required icon is
flashing, the diesel particulate filter is full.
Maintain uninterrupted highway speed for an
automatic regeneration or move the vehicle
to a safe location and initiate a parked
regeneration.
If the DPF Regeneration Required icon is
flashing and the CHECK light illuminates,
the diesel particulate filter is overfull. Engine
performance will be limited. To avoid
further engine derate, immediately move
the vehicle to a safe location and initiate a
parked regeneration, or take the vehicle to an
authorized Prevost dealer.

for service.
