The instructions in this section refer to the keys on
the diagnostic gauge. The Enter key (F) is used when
selecting an option on the diagnostic gauge. The Arrow
keys (G) are used to scroll up or down between options
on the diagnostic gauge screen. The Menu key (H) is
used to access the main menu of options from which the
operator can choose.
Passive Regeneration/Natural Cleaning
Periodically, the exhaust filter will experience higher heat
levels simply through the engine operating at higher
loads. During these times, the higher exhaust heat will
naturally clean a small amount of soot build up in the
exhaust filter. Conversely, unnecessary idling can cause
additional exhaust filter soot to accumulate. For the
best possible engine operation which requires the least
amount of operator interaction, the engine should be
worked at higher load conditions whenever possible and
idling should be kept to a minimum.
Automatic (AUTO) Exhaust Filter Cleaning
NOTE: Operator display icons and procedures can vary in
other applications. The information contained in this
section specifically applies to only OEM engines.
If you are operating a John Deere vehicle, please
see the vehicle operator manual for all exhaust filter
cleaning and handling information and procedures.
NOTE: When Auto or Parked exhaust filter cleaning is
enabled, the exhaust temperature may be high
under no load or light load conditions at certain
times during the exhaust filter cleaning cycle.
Operating the engine in AUTO Mode allows the ECU to
perform intelligent exhaust filter cleaning as required. The
Exhaust Filter Cleaning Indicator will illuminate when the
system is actively performing an exhaust filter cleaning.
During this process, the injector will inject small amounts
of fuel into the exhaust stream to assist in cleaning the
exhaust filter. When the exhaust filter cleaning process
has completed its cycle, the cleaning indicator will
automatically turn off.
CAUTION:
Servicing machine or attachments during exhaust
filter cleaning can result in serious personal
injury. Avoid exposure and skin contact with
hot exhaust gases and components.
During auto or manual/stationary exhaust
filter cleaning operations, the engine will
run at elevated idle and hot temperatures
for approximately 20—50 minutes. Exhaust
gases and exhaust filter components reach
temperatures hot enough to burn people,
ignite, or melt common materials.
CAUTION: If the machine is not in a safe location
for elevated exhaust temperatures, move the
RG17488
—UN—21AUG09
machine to a safe location and check for adequate
fuel level before beginning the exhaust filter
cleaning process. Any PTO driven devices (if
equipped) should be powered off or disconnected.
If the machine is not able to be moved into a safe location,
the operator should temporarily disable auto exhaust
filter cleaning (see Disable Exhaust Filter Cleaning in
the Aftertreatment System Section). If the machine is
located in a safe location, the auto mode should always
be engaged.
To engage the auto exhaust filter cleaning mode:
1 — Press the Menu key on the diagnostic gauge.
2 — Press the Arrow keys to scroll up or down to
EXHAUST FILTER.
3 — Press the Select key.
4 — Press the Arrow keys to scroll up or down to AUTO
EXH FLT CLEAN.
5 — Press the Select key to enable auto exhaust filter
cleaning.
