2014 FORD SUPER DUTY Diesel Supplement Manual

Diesel particulate filter maintenance
You must properly maintain your diesel
particulate filter in order for it to function
properly. Do not disregard the EXHAUST
OVERLOADED DRIVE TO CLEAN and
EXHAUST AT LIMIT DRIVE TO CLEAN
NOW
maintenance messages otherwise
system damage could result that your
warranty may not cover.
Failure to perform active or operator
commanded regeneration when instructed
might result in a clogged diesel particulate
filter that your dealer cannot clean. If your
diesel particulate filter fills beyond what
can safely be regenerated, active
regeneration and operator commanded
regeneration will be disabled. This could
result in irreversible damage to the filter
requiring replacement that your warranty
may not cover. If your vehicle is not
equipped with operator commanded
regeneration, check with your dealer for
availability.
Once the diesel particulate filter is full of
exhaust particles, the engine control
module will command the exhaust system
to clean the filter through a process called
active regeneration. Active regeneration
requires the engine computer to raise the
exhaust temperature to eliminate the
particles. During cleaning, the particles
convert to harmless gasses. Once cleaned
the diesel particulate filter will then be
ready to continue trapping exhaust
particles.
The regeneration process operates more
efficiently when you safely operate your
vehicle at least 30 mph (48 km/h) with a
steady pedal for approximately 20 minutes
to complete the process. The frequency
and duration of regeneration will fluctuate
by how you drive your vehicle, outside air
temperature, and altitude. For most driving,
regeneration frequency will vary from 100 - 500 miles (161 - 805 km) between
occurrences and each occurrence will last
from 9 - 20 minutes. You can usually
reduce the duration of regeneration if you
maintain a constant speed above 30 mph
(48 km/h).
When the engine control module detects
that the diesel particulate filter is nearly
full of particulates and you are not
operating your in a manner to allow
effective automatic cleaning, the
information display will display
EXH
OVERLOADED DRIVE TO CLEAN for
base information display and Exhaust
Overloaded Drive to Clean for the
optional information display. These
messages appear as a reminder for you to
drive in order to clean the diesel particulate
filter. If you operate your vehicle in a
manner to allow effective automatic
cleaning, the information display will
display a cleaning exhaust filter message,
which is the normal regeneration process.
See the Information Displays chapter of
the Owner Guide for more information.
You can also choose operator commanded
regeneration to clean the exhaust system
at this point. See How to start operator
commanded regeneration later in this
chapter.
If you are not able to drive in a manner that
allows effective automatic cleaning (active
regeneration) or you choose to perform
regeneration of the diesel particulate filter
(cleaning) while at idle (stationary), then
operator commanded regeneration would
need to be performed. See operator
commanded regeneration later in this
chapter.

Super Duty (TFA) Fuel and Refueling

Operator Commanded Regeneration
If your vehicle is operated with significant
stationary operation, low speed drive
cycles less than 25 mph, short drive cycles,
a drive time is less than 10 - 15 minutes or
the vehicle does not fully warm up, passive
and active regeneration may not
sufficiently clean the diesel particulate
filter system. Operator commanded
regeneration allows you to manually start
regeneration of the diesel particulate filter
at idle (while stationary) to clean the filter.
If you are not sure whether your vehicle is
equipped with this feature, contact an
authorized dealer.
When to perform Operator Commanded
Regeneration
Use the Operator Commanded
Regeneration feature when the EXH
OVERLOADED DRIVE TO CLEAN
message appears in the information
display and:
• the operator is not able to drive in
manner that allows effective
automatic cleaning (active
regeneration),
• or the operator instead wishes to
manually start regeneration (cleaning)
of the diesel particulate filter while the
vehicle is idle (stationary).
Operator Commanded Regeneration
precautions and safe exhaust position WARNING
Failure to comply with the following
instructions for operator
commanded regeneration may result
in fire, serious injury, death and/or property
damage. Before you start operator commanded
regeneration, do the following: •
Place your vehicle in
P (Park) with the
parking brake set on stable, level
ground
• You must park your vehicle outside of
any structure
• Your vehicle must be 10 – 15 feet (3 –
5 meters) away from any obstructions
and must be away from materials that
can easily combust or melt (for
example, paper, leaves, petroleum
products, fuels, plastics and other dry
organic material)
• Make sure there is a minimum of 1/8
tank of fuel
• Make sure all fluids are at proper levels
Make sure that the louvers (holes) located
at the tip of the exhaust are also clear of
any obstructions as they are used to
introduce fresh air into the tailpipe to cool
the exhaust gas as it leaves. See Cleaning
the Exhaust
(page 53).
How to start Operator Commanded
Regeneration WARNING
Stay clear of exhaust tip during
regeneration. You or others can be
burned.
Note:
You cannot use the operator
commanded regeneration until the diesel
particulate filter load percentage has
reached 100% (Full). The diesel particulate
filter load percentage will fluctuate up and
down when driving your vehicle due to active
and passive regenerations.
Note: During the use of operator
commanded regeneration, you may observe
a light amount of white smoke. This is
normal. You cannot use the operator
commanded if the service engine
soon light is illuminated.

Information display procedure
Start with your vehicle engine fully warmed
and then press the Info button on the
steering wheel until the information display
reads one of the following choices:
If you have warmed your vehicle up and
the diesel particulate filter needs cleaning,
a message requesting permission to initiate
filter cleaning will be displayed EXHST
XX% FULL CLEAN? Y/N or EXHAUST
FULL CLEAN? Y/N. Answer yes to this
prompt and then follow the prompts
regarding exhaust position as needed to
initiate Operator Commanded
Regeneration. Be sure to understand each
prompt. If you are not sure what is being
asked by each prompt, contact an
authorized dealer. The display will confirm
the operation has started and when it has
finished. If you have warmed your vehicle
up and the diesel particulate
filter is near or at saturation, the
powertrain fault indicator will illuminate
and message requesting permission to
initiate filter cleaning will be displayed
EXH AT LIMIT CLEAN? Y/N. Answer yes
to this prompt and then follow the
prompts regarding exhaust position as
needed to initiate Operator Commanded
Regeneration. Be sure to understand each
prompt. If you are not sure what is being
asked by each prompt, contact an
authorized dealer. The display will confirm
the operation has started and when it has
finished. You can also drive to clean the
filter. See Active regeneration earlier in this
chapter. The service engine soon light will
illuminate and the following
message
EXH OVER LIMIT
SERVICE NOW will appear when the
system is at the point of oversaturation.
You will not be able to allow cleaning. You
must have your vehicle serviced by an
authorized dealer. Once operator commanded regeneration
starts, the engine
’s rpm will rise to
approximately 2,000 - 2,400 rpm and the
cooling fan will increase speed; you will
hear a change in audible sound due to the
fan and engine speed increase.
It is not necessary to open the hood on the
engine compartment. Once operator
commanded regeneration is complete, the
engine rpm and fan will return to normal
idling. The exhaust system will remain very
hot for several minutes even after
regeneration is complete. Do not reposition
the vehicle over materials that could burn
until the exhaust system has had sufficient
time to cool. Depending on the amount of
soot collected by the diesel particulate
filter, ambient temperature, and altitude,
operator commanded regeneration may
last from 10 to 25 minutes.
How to interrupt or cancel Operator
Commanded Regeneration
If you need to cancel the operator
commanded regeneration, pressing the
brake, accelerator, or shutting off the
vehicle will stop the procedure. Depending
on the amount of time you allowed the
operator commanded regeneration to
operate, soot may not have had sufficient
time to be eliminated, but the exhaust
system and exhaust gas may still be hot.
If you shut your vehicle off during operator
commanded regeneration, you will notice
turbo flutter. This is a normal consequence
caused by shutting off a diesel engine
during boosted operation and is considered
normal.
Filter service and maintenance
Over time, a slight amount of ash will build
up in the diesel particulate filter, which is
not removed during the regeneration
process. The filter may need to be removed
for ash cleaning at approximately 120,000
miles (193,000 km) or greater (actual
mileage can vary greatly depending upon
32
Super Duty (TFA) Fuel and Refueling

engine/vehicle operating conditions) and
replaced with a new or remanufactured
(ash cleaned) part. The filter may need to
be replaced at approximately 250,000
miles (400,000 km) depending upon
vehicle operating conditions.
In both cases, the engine control
system will set a service light to
inform you to bring the vehicle
to the dealer for service.
If there are any issues with the diesel
particulate filter system a service light will
be set by the engine control system to
inform you to bring your vehicle into an
authorized dealer for service. Powertrain fault indicator or
Service engine soon
Resonator and Tailpipe assembly
maintenance WARNINGS
Failure to maintain the functional
holes, in the tailpipe section of the
exhaust, clean and free of debris or
foreign material may result in the holes
becoming blocked or plugged. Do not
modify or remove the tail-pipe section.
Blocked or plugged holes or
removal/modification of the system could
result in elevated exhaust gas
temperatures which may result in
vehicle/property damage or personal
injury. The normal operating temperature
of the exhaust system is very high.
Never work around or attempt to
repair any part of the exhaust system until
it has cooled. Use special care when
working around the diesel oxidation
catalytic converter and/or the diesel
particulate filter (DPF). The diesel WARNINGS
oxidation catalytic converter and/or the
DPF heats up to a high temperature after
only a short period of engine operation and
can stay hot even after the engine is turned
off. Failure to follow these instructions may
result in personal injury. Note:
Additions of aftermarket devices or
modifications to the exhaust system can
reduce the effectiveness of the exhaust
system as well as cause damage to the
exhaust system or engine. These actions
may also affect your vehicle ’s warranty. See
the Warranty Guide for more information.
The diesel resonator tail-pipe assembly is
a uniquely functioning device that
accompanies the diesel particulate filter
assembly. The tail-pipe assembly serves
multiple functions. First, it serves as an
acoustic device to attenuate exhaust noise.
Second, it provides an exit path for the
exhaust from your vehicle. It also helps
control the temperature of the exhaust
during diesel particulate filter regeneration
events. The visible holes in each leg of the
twin tip and the holes under the shield just
inboard of the right rear tire(s) are
functional. You need to keep the holes
clear of mud, debris or foreign material to
maintain proper function of the exhaust
system. Clean and remove debris or foreign
material if present as needed. Spraying
with a hose during regular washing of your
vehicle should help keep holes clean and
clear of debris or foreign material.

Emission Control System(s) Laws
WARNING
Do not remove or alter the original
equipment floor covering or
insulation between it and the metal
floor of the vehicle. The floor covering and
insulation protect occupants of the vehicle
from the engine and exhaust system heat
and noise. On vehicles with no original
equipment floor covering insulation, do not
carry passengers in a manner that permits
prolonged skin contact with the metal
floor. Provide adequate insulation. Failure
to follow these instructions may result in
fire or personal injury. In the U.S. federal law and certain state
laws prohibit removing or rendering
inoperative emission control system(s).
Similar federal or provincial laws may
apply in Canada. Ford recommends
against any vehicle modification without
determining applicable law.
Tampering with emissions
control systems (including
related sensors and the diesel
exhaust fluid injection system) can result
in reduced engine power and the
illumination of the service engine soon
light.
Tampering with a Noise Control
System
Federal law prohibits the following acts or
the causing thereof: (1) The removal or
rendering inoperative by any person other
than for purposes of maintenance, repair
or replacement of any device or element
of design incorporated into any new vehicle
for the purpose of noise control prior to its
sale or delivery to the ultimate purchaser
or while it is in use, or (2) the use of the
vehicle after such device or element of
design has been removed or rendered
inoperative by any person. Among those acts, which the U.S.
Environmental Protection Agency may
presume to constitute tampering are the
acts listed below:
•
Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer ’s
specifications.
The complexity of the diesel engine makes
it so the owner is discouraged from
attempting to perform maintenance other
than the services described in this
supplement.
If you experience difficult starting the
engine, rough idling, excessive exhaust
smoke, a decrease in engine performance
or excess fuel consumption, perform the
following checks:
• A plugged or disconnected air inlet
system or engine air filter element
• Water in the fuel filter and water
separator
• A clogged fuel filter
• Contaminated fuel
• Air in the fuel system, due to loose
connections
• An open or pinched sensor hose
• Check engine oil level
• Wrong fuel or oil viscosity for climactic
conditions
If these checks do not help you correct the
engine performance problem you are
experiencing, consult an authorized dealer.
