Diesel Messages And Warnings — 6.7L
Cummins Diesel Engine
Diesel Particulate Filter (DPF) Messages
The Cummins diesel engine meets all diesel
emissions standards, resulting in one of the
lowest emitting diesel engines ever produced.
To achieve these emissions standards, your
vehicle is equipped with a state-of-the-art
engine and exhaust system. These systems are
seamlessly integrated into your vehicle and
managed by the Powertrain Control Module
(PCM). The PCM manages engine combustion
to allow the exhaust system’s catalyst to trap
and burn Particulate Matter (PM) pollutants,
with no input or interaction on your part.

20_DJD2_OM_EN_USC_t.book Page 124

GETTING TO KNOW YOUR INSTRUMENT PANEL125
Your vehicle has the ability to alert you to addi-
tional maintenance required on your vehicle or
engine. The following messages may display in
your instrument cluster display:
Perform Service — Your vehicle will require
emissions maintenance at a set interval. To
help remind you when this maintenance is
due, the instrument cluster display will
display “Perform Service”. When the
“Perform Service” message is displayed in
the instrument cluster display it is necessary
to have the emissions maintenance
performed. Emissions maintenance may
include replacing the Closed Crankcase
Ventilation (CCV) filter element. The proce -
dure for clearing and resetting the "Perform
Service" indicator message is located in the
appropriate Service Information.
Exhaust System — Regeneration Required
Now — "Exhaust Filter XX% Full Safely Drive at
Highway Speeds to Remedy" will be displayed
in the instrument cluster display if the
exhaust particulate filter reaches 80% of its
maximum storage capacity. Under conditions
of exclusive short duration and low speed
driving cycles, your Cummins diesel engine
and exhaust after-treatment system may
never reach the conditions required to
remove the trapped Particulate Matter (PM).
If this occurs, the “Exhaust Filter XX% Full
Safely Drive at Highway Speeds to Remedy”
message will be displayed in the instrument
cluster display. If this message is displayed,
you will hear one chime to assist in alerting
you of this condition
By simply driving your vehicle at highway
speeds for as little as 45 minutes, you can
remedy the condition in the particulate filter
system and allow your Cummins diesel
engine and exhaust after-treatment system
to remove the trapped Particulate Matter
(PM) and restore the system to normal oper -
ating condition.Exhaust System — Regeneration In Process
Exhaust Filter XX% Full — Indicates that the
Diesel Particulate Filter (DPF) is self-cleaning.
Maintain your current driving condition until
regeneration is completed.
Exhaust System — Regeneration Completed
— This message indicates that the Diesel
Particulate Filter (DPF) self-cleaning is
completed. If this message is displayed, you
will hear one chime to assist in alerting you of
this condition.
Exhaust Service Required — See Dealer Now
— This message indicates regeneration has
been disabled due to a system malfunction.
At this point the engine Powertrain Control
Module (PCM) will register a fault code, the
instrument panel will display a MIL light.
WARNING!
A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials might be grass or leaves coming
into contact with your exhaust system. Do not
park or operate your vehicle in areas where
your exhaust system can contact anything
that can burn.
CAUTION!
See an authorized dealer, as damage to the
exhaust system could occur soon with
continued operation.

Exhaust Filter Full — Power Reduced See
Dealer — This message indicates the PCM
has derated the engine to limit the likelihood
of permanent damage to the after-treatment
system. If this condition is not corrected and
a dealer service is not performed, extensive
exhaust after-treatment damage can occur.
To correct this condition it will be necessary
to have your vehicle serviced by your local
authorized dealer.
NOTE:
Failing to follow the oil change indicator,
changing your oil and resetting the oil change
indicator by 0 miles remaining will prevent the
diesel exhaust filter from performing it's
cleaning routine. This will shortly result in a
Malfunction Indicator Light (MIL) and reduced
engine power. Only an authorized dealer will be
able to correct this condition.Cold Ambient Derate Mode Messages
The vehicle will display messages when a
derate (engine power reduction) is activated to
protect the engine during start up in cold
ambient temperatures.
Engine Power Reduced During Warmup —
This message will display during start up
when the ambient temperature is between
10°F (-12°C) and -10°F (-23°C).
Engine Power Reduced Up To 30 Sec
(Seconds) During Warmup — This message
will display during start up when the ambient
temperature is between -10°F (-23°C) and
-25°F (-32°C).
Engine Power Reduced Up To 2 Min
(Minutes) During Warmup — This message
will display during start up when the ambient
temperature is -25°F (-32°C) and below.
Your vehicle is equipped with an engine
warm up protection feature that may limit
engine performance after cold starting at low
ambient temperatures. The length of time
engine speed is limited is dependent upon
engine coolant temperature. Engine speed
may be briefly limited to 1000 RPM after
starting with coolant temperature below freezing conditions, and may be limited to
1000 RPM for up to approximately 2 minutes
under more severe cold conditions.
Coolant Low
— This telltale will turn on to indi -
cate the vehicle coolant level is low. Refer to
“Dealer Service” in “Servicing And Mainte -
nance” for more information.
Diesel Exhaust Fluid (DEF) Warning
Messages
There are four different messages which are
displayed if the vehicle detects that the DEF
system has been filled with a fluid other than
DEF, has experienced component failures, or
when tampering has been detected. The vehicle
may be limited to a maximum speed of 5 MPH
(8 km/H) if the DEF system is not serviced
within less than 200 miles (322 km) of the fault
being detected.
When the DEF system needs to be serviced the
following warnings will display:
DEF Low Refill Soon — This message will
display when the low level is reached, during
vehicle start up, and with increased
