The underbody mounted filter housing will cause the engine not to run if:
• No filter is installed.
NOTE:
• Using a fuel filter that does not meet the manufacturer's filtration and water
separating requirements can severely impact fuel system life and reliability.
• The WIF sensor is re-usable. Service kit comes with new o-ring for filter canister
and WIF sensor.
CAUTION!
• Diesel fuel will damage blacktop paving surfaces. Drain the filter into an
appropriate container.
• Do not prefill the fuel filter when installing a new fuel filter. There is a possibility
debris could be introduced into the fuel filter during this action. It is best to
install the filter dry and allow the in-tank lift pump to prime the fuel system.
• If the “Water In Fuel Indicator Light” remains on, DO NOT START the engine
before you drain water from the fuel filter to avoid engine damage.
EXHAUST REGENERATION
Under certain conditions, your Cummins diesel engine and exhaust after-treatment
system may never reach the conditions required to remove the trapped particulate
matter. If this occurs, the “Exhaust System — Regeneration Required Now” message
will be displayed on the screen in your instrument cluster and you will hear one chime
to alert you of this condition. Driving your vehicle at highway speeds for as little as
45 minutes can remedy the condition and allow the engine and exhaust after-
treatment system to remove the trapped particulate matter.
NOTE:
Under typical operating conditions, NO indications of regeneration state will be
displayed. If you do reach 80% of filter capacity, the following messages will assist
you in inducing and understanding the regeneration process.
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.
