Exhaust Regeneration - RAM 1500 2014 User Manual

• Diesel fuel will damage blacktop paving surfaces. Drain the filter into an appro-
priate 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
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 EVIC screen in your 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.
Perform Service
Your vehicle will require emissions maintenance at a set interval. To help remind you
when this maintenance is due, the Electronic Vehicle Information Center (EVIC) will
display "Perform Service". When the "Perform Service" message is displayed on the
EVIC it is necessary to have the emissions maintenance performed. Emissions mainte-
nance may include replacing the Closed Crankcase Ventilation (CCV) filter element, and
cleaning of the EGR Cooler. The procedure for clearing and resetting the "Perform
Service" indicator message is located in the appropriate Service Information.
Exhaust System — Regeneration Required Now
"Exhaust System—Regeneration Required Now" will be displayed on the EVIC if the
exhaust particulate filter reaches 80% of its maximum storage capacity.
Exhaust Filter XX% Full
Indicates that the Diesel Particulate Filter (DPF) is approaching full.
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.
