General Information
Refilling DEF Tank
IMPORTANT NOTE: If DEF is filled into engine fuel
tank or other fluid compartment, do not operate
engine until system is properly purged of DEF.
Contact your John Deere dealer immediately to
determine how to clean and purge the system.
NOTE: Use only distilled water to rinse components that
are used to deliver DEF. Tap water can contaminate DEF.
If distilled water is not available, rinse with clean tap
water, then thoroughly rinse with ample amounts of DEF.
Reasonable care should be taken when refilling the DEF
tank. Verify the DEF tank cap area is free of debris before
removing the cap. Wipe clean with a lint free cloth to
remove debris from tank cap. Seal DEF containers
between use to prevent contamination and evaporation.
Avoid splashing DEF, and do not allow DEF to come into
contact with skin, eyes, or mouth.
DEF can be corrosive to materials such as steel, iron,
zinc, nickel, copper, aluminum, and magnesium. Use
suitable containers to transport and store DEF.
Containers made of polyethylene, polypropylene, or
stainless steel are recommended.
NOTE: Keep anything used to store or dispense DEF
clean of dirt and dust. Wash and rinse containers or
funnels thoroughly with distilled water to remove
contaminants.
If an unapproved fluid, such as diesel fluid or coolant is
added to the DEF tank, contact your John Deere
dealer immediately to determine how to clean and
purge the system.
If water has been added to the DEF tank, a tank cleaning
is necessary. After refilling the tank, check the DEF
concentration. See Testing DEF. The operator must
maintain appropriate DEF levels at all times. Check the
DEF level daily and refill the tank as needed. The filling
port is identified by a blue colored cap embossed with the
DEF symbol.
Selective Catalytic Reduction (SCR)
Monitoring
This unit is equipped with a selective catalytic reduction
(SCR) system to meet Tier 4 EPA emissions standards.
This section gives an explanation of the indicators that
are displayed on the SCR status page of the engine tab.
To access the SCR status page, press any direction
button (▲, ►, ▼, ◄) to enter the maintenance screens,
and when on the engine tab, press the ▼ button to toggle
through the pages until the SCR status page appears.
There are four areas on the SCR status page that
communicate various information to the operator. The
areas and the indicators that appear in those areas are
explained here:
• HEST Lamp (High Exhaust System
Temperature): This area displays the regeneration
underway indicator above the words HEST LAMP -
SOLID when the unit is in the process of the
exhaust catalyst. During the regeneration process,
the exhaust temperature will be very high.
• SCR Lamp: This area displays the regeneration
indicator above the words SCR LAMP - SOLID
when auto exhaust filter cleaning is enabled. When
the unit is being operated with auto exhaust filter
cleaning disabled, the indicator will begin to flash
above the words SCR LAMP - FLASHING if the
soot load level goes above 80%.
• SCR Inhib: This area displays the disabled
regeneration indicator above the words SCR INHIB
- SOLID when auto exhaust filter cleaning is
disabled.
• Alarm: This area will display the engine alarm
indicator above the words ALARM - SOLID when
an alarm condition occurs. This area displays
different text depending upon which alarm
condition occurs.
See DOC and SCR Cleaning Operations for more
information on the operation of auto exhaust filter
regeneration and service regeneration.
DPF Regeneration Lamps
Depending upon the Engine Type selected in the
module’s configuration, the Engine section may include
the DPF Regeneration Lamps page. This page contains
icons (see Figure 2-18) to show the status of various
ECU functions, some of which are applicable to Tier 4
engine requirements. The icons flash at different rates to
show the status of the ECU function, refer to the engine
manufacturer for more information about this.
