Diesel Particulate Filter (DPF) Messages
The Cummins® diesel engine meets all EPA Heavy Duty
Diesel Engine 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.
