2012 Trip
Malfunction Indicator Lamp (MIL):
The Malfunction Indicator
Lamp (MIL) will illuminate
when an emissions fault is
detected in the engine control
system. The emission system
will need to be serviced at
the earliest opportunity.
DPF Lamp Warning System:
Indicator lamps will illuminate in stages of
severity as to the condition of the DPF.
Stage One:
The DPF lamp glows steady.
This means that an active
regeneration cycle is necessary.
Stage Two:
The DPF lamp flashes. The
DPF is clogged to the point that
a rolling or parked regeneration
needs to be performed at the
earliest opportunity.
Stage Three:
The DPF lamp flashes. A
warning alarm will also sound
indicating an immediate
necessity to regenerate the
filter. The DPF is clogged to the
point a parked regeneration is
required as soon as possible. Engine control
circuits will limit engine power to 70%.
Stage Four:
The DPF lamp will extinguish
and the Stop Engine lamp will
illuminate. Engine control
circuits will limit engine power
to 20% so the motorhome can
be moved to a safe location.
Shut off the engine as soon as possible to
avoid severe engine and/or system component
damage. Do not drive the motorhome in this
condition. The DPF will need to be removed
for repair.
Parked Regeneration:
Traffic and road conditions, short run periods
and excessive idling can lead to clogging of
the DPF by not allowing regeneration (passive
or active) to occur. If the DPF indicator
lamps are at Stage 2 or 3, it will be necessary
to perform a parked regeneration if unable
to travel at freeway speeds while in Stage
2. A parked regeneration cycle can last up
to 20 minutes. During active regeneration,
fuel is introduced into the exhaust system.
Engine speed is automatically increased to
a predetermined speed. A successful parked
regeneration is indicated by the DPF lamp
turning off and the engine returning to normal
idle speed. The HEST lamp may remain
illuminated for a period of time as exhaust
system temperature will remain elevated.
NOTE:
A parked regeneration can also be
performed at Stage 1.
Request Regen Switch:
The Request Regen switch
performs two functions. It
is used to initiate an active
regeneration when parked or
cancel an active regeneration
cycle when parked. If the
DPF is in Stage 3, it is
recommended to initiate a
stationary regeneration cycle
as soon as possible.
Initiating Stationary Regeneration:
The DPF lamp must be on before the
engine control circuits will allow a stationary
regeneration. The motorhome must be parked
on a suitable surface and clear of surroundings
that
Do Not
pose a fire or safety hazard.
Engine is running with coolant
temperature 170 Fº or greater.
Transmission is in neutral and park
brake applied.
Throttle in idle position. Foot brake
pedal is not applied.
Press and hold the regeneration switch
for two seconds.
The “bar” light will glow steady. Engine
speed will ramp up to a predetermined speed
followed a short time later by illumination of
the HEST lamp. The stationary regeneration
cycle will last approximately 20 minutes.
Regeneration is successful when engine speed
returns to idle and the DPF lamp goes out.
The HEST lamp will remain illuminated until
exhaust temperature returns to normal.
