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 stan
-
dards, 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.
Your vehicle has the ability to alert you to
additional 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 mainte
-
nance 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 main
-
tenance performed. Emissions mainte
-
nance may include replacing the Closed
Crankcase
Ventilation
(CCV)
filter
element. The procedure for clearing and
resetting the "Perform Service" indicator
message is located in the appropriate
Service Information.

the trapped PM. If this occurs, the

Highway Speeds to Remedy” message will
be displayed in the instrument cluster
display. If this message is displayed, you

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.
