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.
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.
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 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 procedure 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 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 PM and restore the
system to normal operating condition.
