Operation
Exhaust Diesel Particulate Filter Regeneration
This vehicle is equipped with a Diesel Particulate Filter
(DPF) to meet 2010 emissions requirements. The DPF traps
exhaust particulate matter generated by normal engine usage.
Periodically, the engine control system will perform a “cleaning”
of the filter, known as Normal Regeneration. This process is
transparent to the operator and occurs during normal vehicle
operation.
In some cases the engine control system is unable to manage
soot levels in the DPF through Normal Regeneration. When
this occurs the DPF indicator will illuminate solid YELLOW on
the instrument panel gauge cluster advising that action must be
taken. At this time the vehicle should then be driven at highway
speeds, or pulled over to perform a Parked Regeneration (See
Parked Regeneration Procedure).
If no action is taken the
DPF indicator will begin to flash indicating that the filter is full.
The vehicle should then be pulled safely off the roadway and
a Parked Regeneration should be performed. If the vehicle is
driven beyond the initial two warning stages, a loss of engine
performance (de-rate) will occur. Ignoring the need for a Parked
Regeneration, when required, can result in a warning for
excessive exhaust temperatures, and a requirement to shut the
engine off and not restart it until the DPF has been serviced by
a technician. It is important to perform a Parked Regeneration
when required. Failure to do so could be mission disabling and
result in the vehicle being towed.
See the following information for a detailed explanation of DPF
indicators and the corresponding procedures that must be
followed.
WARNING
Failure to perform a Parked Regeneration when
exhaust filter indicator is ON will cause the engine
to lose power and eventually shutdown.
When performing Parked Regeneration, make
certain vehicle is safely off of the roadway
and exhaust pipe is away from people, or any
flammable materials or structures.
Failure to follow these instructions may result in
a loss of engine power, vehicle speed, increased
exhaust
temperatures, and may cause an
accident or fire resulting in property damage,
personal injury, or death.
There will be three levels of indication that the vehicle’s exhaust
filter is accumulating soot and needs to be cleaned, each with
an increasing urgency for action.
NOTE: A Level 1 indication may disappear or a Level 2 may
revert to a Level 1, if the vehicle is driven on highway at
highway speeds for an extended period. This process of auto
regeneration of the exhaust filter is activated when the engine
load is increased as a result of highway driving at highway
speeds.
If the DPF indicator does not reduce in level or
disappear, a Parked Regeneration must be performed.
NOTE: The following table is a typical representation of 2010
DPF emissions procedures (See visor for vehicle federal
emissions label).
