2015 FORD SUPER DUTY reset

The powertrain and glow plug control
modules electronically control the glow
plug system. After you switch the ignition
on the glow plug control module
immediately energizes the glow plugs. The
glow plug control module using the engine
coolant temperature, barometric pressure
sensor and environmental temperature
sensor will determine how long the glow
plugs stay energized. The required time for
the glow plugs to be energized decreases
as the coolant temperature, barometric
pressure and environmental temperature
increase.
Glow Plug
Engine and secondary cooling system
The cooling system contains a primary
cooling loop to cool the engine and a
secondary cooling loop to cool the
transmission, charge air, and fuel. The
coolant serves three primary purposes: to
provide heat transfer, freeze point
protection, and corrosion protection using
additives.
Vehicles with diesel engines typically are
used to carry heavy loads and accumulate
mileage rapidly. These two factors may
cause the additives in the coolant to wear
out in a shorter time. For more information
about coolant additives and coolant
change intervals See Engine Coolant
Check (page 45). . Operating the engine
with insufficient coolant or coolant additive
can cause severe engine damage
Diesel Particulate Filter system
Your vehicle is equipped with a diesel
particulate filter in the exhaust system. The
diesel particulate filter reduces carbon
emissions by trapping exhaust particulates
(soot) before they reach the tailpipe. You
must properly maintain your diesel
particulate filter in order for it to function properly. Regeneration of the diesel
particulate filter occurs automatically
during operation above 30 mph (48 km/h)
and requires no actions from the driver. If
you do a lot of idling or stop and go driving,
pay attention to maintenance messages
that alert you when you need to drive to
clean the diesel particulate filter, or
perform operator commanded
regeneration. See
Emission Control
System (page 30).
Selective catalytic reduction system
Your vehicle is equipped with a selective
catalytic reduction system designed to
reduce emission levels of nitrogen oxides
from the exhaust of your diesel engine. This
system relies on the use of Diesel Exhaust
Fluid (DEF) that you must replenish at
certain intervals. Failure to maintain proper
DEF levels or if the DEF becomes
contaminated will result in vehicle speed
limitations or result in your vehicle entering
an idle-only mode. See
Selective
Catalytic Reduction System (page 21).
Speed control
If your vehicle speed goes outside a
predetermined range from the set speed,
the RSM (Resume) function will not reset
your vehicle speed. You will need to reset
your vehicle speed with the SET+ or SET-
button after reaching the desired speed
using the accelerator pedal.
Minor Troubleshooting Guide
If the engine won ’t crank WARNING
Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after
handling. 5
Super Duty (TFA) , enUSA Introduction

Turn on the headlights. If the lights are dim,
do not go on at all or when the ignition is
turned to START the lights become dim or
go out, the battery connections may be
loose or corroded, or the battery may be
discharged. If there is a clicking or
stuttering sound coming from the engine
compartment when you turn the key to
START, this may also indicate a loose or
corroded battery connection.
Check the battery connections at the
battery posts, cable connection to the
engine grounding point and at the starter
connection.
If you suspect a discharged battery, have
it checked and corrected.
•
The gearshift lever must be in P (Park)
or N (Neutral) in order for the starter
to operate.
• Try operating the starter switch several
times. This operation may clean
potentially corroded contacts or make
the switch temporarily operable until
you can reach the dealer.
• If all electrical connections are tight
and you need assistance to start, refer
to Jump Starting in the Roadside
Emergencies chapter of your Owner ’s
Manual.
If engine cranks but won ’t start
Prolonged starter cranking (in excess of 10
seconds) could cause damage to the
starter motor or the high-pressure fuel
pump. •
Check the fuel gauge. You may be out
of fuel. If the gauge shows that there
is fuel in the tank, the trouble may be
in the electrical system or the fuel
system. If equipped with an auxiliary
tank, be sure that the tank control
switch is set for the tank with fuel and
not on an empty tank.
• Leaving your ignition key turned to on
for over two minutes without starting
may make starting difficult because
the glow plugs will cease activation.
Reset the system by turning the ignition
key to off and then back to on again.
Note: If the system is out of fuel and the
engine will not start, do not continue
cranking the engine. Continued cranking can
damage the high-pressure fuel pump.
If the engine runs hot
The following could cause the engine to
overheat:
• Lack of coolant
• Dirty cooling system.
• Plugged radiator fins, A/C condenser
and/or oil cooler
• Malfunctioning fan drive
• Driving with frozen coolant
• Sticking thermostat
• Overloading or pulling heavy trailers
during hot weather
• Grill or radiator air blockage
• Slipping or missing drive belt
• Plugged or very dirty air filter

2.
When the glow plug pre-heat indicator
turns off, turn the key to start and
release the key as soon as the engine
starts. After starting the engine, the
glow plugs may remain on for a period.
If you do not start the engine before
the glow plug activation time ends, you
will need to reset the glow plugs by
turning the key to off.
3. After the engine starts, allow it to idle for about 15 seconds. This is to protect
the engine. Do not increase engine
speed until the oil pressure gauge
indicates normal pressure.
Cold Weather Operation
Note: Idling in cold weather does not heat
the engine to its normal operating
temperature. Long periods of idling,
especially in cold weather, can cause a
buildup of deposits which can cause engine
damage.
Changing to a lighter grade engine oil also
makes starting easier under these
conditions. Refer to Engine oil
specifications. See Technical
Specifications (page 57).
Diesel fuel is adjusted seasonally for cold
temperatures. Diesel fuel which has not
been properly formulated for the ambient
conditions may gel which can clog the fuel
filters. One indication that the fuel filter(s)
may be clogged is if the engine starts, stalls
after a short time, and then does not
restart. If you have been using biodiesel,
you may need to use a fuel with lower
biodiesel content, try another brand, or
discontinue using biodiesel. Do not use
alcohol based additives to correct fuel
gelling. This may result in damage to the
fuel injectors and system. Use the proper
anti-gel and performance improvement
product. See
Technical Specifications
(page 57). Your vehicle is equipped with a fuel and
water separator that recirculates fuel from
the engine to help prevent fuel filter
clogging. To avoid engine fuel starvation
during cold weather operation of 32°F
(0°C) or below, we recommended that
the fuel level in your tank should not drop
below 1⁄4 full. This helps prevent air from
entering the fuel system and stalling the
engine.
Your vehicle is equipped with a selective
catalyst reduction system that uses Diesel
Exhaust Fluid (DEF) to operate properly.
You need to replenish your vehicle
’s DEF
at certain intervals. When filling your
vehicle ’s DEF tank in cold weather, you
must take special care to prevent damage
to the tank. See
Selective Catalytic
Reduction System (page 21).
In cold weather below 32°F (0°C), the
engine may slowly increase to a higher idle
speed if left idling in P (Park). As the engine
warms-up, the engine sound level
decreases due to the activation of
PCM-controlled sound reduction features.
If you operate your vehicle in a heavy
snowstorm or blowing snow conditions,
snow and ice can clog the engine air
induction. If this occurs, the engine may
experience a significant reduction in power
output. At the earliest opportunity, clear
all the snow and/or ice away from inside
the air filter assembly. Remove the air
cleaner cover and the pleated paper filter,
leaving the foam filter in and remove any
snow or ice. Make sure you install the foam
filter correctly in place. Remove any debris,
snow or ice on the foam filter by brushing
the surface with soft brush. Once you have
cleared all of the debris, reinstall the air
filter and assembly.
Do not use water, solvents, or a hard brush
for cleaning the foam filter.

Idle Control
Your vehicle may have a factory option for
a stationary elevated idle control through
dash-mounted upfitter switches that
allows the operator to elevate the idle rpm
for extended idle periods, as well as
aftermarket equipment such as PTO
operation. You must configure this feature
even if ordered from the factory. See your
authorized dealer for required upfitting.
Operation in Snow and Rain
Vehicle operation in heavy snowfall or
extreme rain conditions may feed
excessive amounts of snow or water into
the air intake system. This could plug the
air filter with snow and may cause the
engine to lose power and possibly shut
down.
We recommend the following actions after
operating your vehicle up to 200 miles
(320 kilometers) in snowfall or extreme
rain:
•
Snow: At the earliest opportunity, open
the hood and clear all the snow and ice
from the air filter housing inlet (do not
remove the foam filter) and reset the
air filter restriction gauge.
Note: Removal of the foam filter degrades
your vehicle performance during snow and
hot weather conditions.
• Extreme rain: The air filter dries after
about 15– 30 minutes at highway
speeds. At the earliest opportunity,
open the hood and reset the air filter
restriction gauge.
Refer to Air filter and restriction gauge in
the Maintenance chapter for more
information. See Changing the Engine
Air Filter (page 50). Operation in Standing Water
Ingestion of water into the diesel engine
can result in immediate and severe
damage to the engine. If driving through
water, slow down to avoid splashing water
into the intake. If the engine stalls, and you
suspect ingestion of water into the engine,
do not try to restart the engine. Consult
your dealer for service immediately.
Your fuel tank vents to the atmosphere by
valves on top of the tank and through the
fuel cap. If water reaches the top of the
tank, the valves may pull water into the
fuel tank. Water in the fuel can cause
performance issues and damage the fuel
injection system.
SWITCHING OFF THE ENGINE
Turn the ignition to the off position.
To prolong engine life (especially after
extended high speed, high ambient
temperature, or high GVW/GCW operation,
such as heavy loads or heavy trailers), it is
recommended that a hot engine be idled
for 3-5 minutes. This allows the
turbocharged engine to cool down. For
more information on GVW/GCW, see the
Load Carrying chapter in your Owner
’s
Manual.
ENGINE IDLE SHUTDOWN
Your vehicle may be equipped with an
engine idle shutdown system. This system
automatically shuts down your engine
when it has been idling in
P (Park) or N
(Neutral) for five minutes (parking brake
set) or 15 minutes (parking brake not set).
When the engine idle shutdown process
has started:

Rapid Heat Supplemental Heating
System
Note: Additional aftermarket electrical
loads operated during engine warm up may
affect the performance of the rapid heat
supplemental heater. The optional rapid heat feature is an
electrically powered device that provides
supplemental heat during engine warm up.
During initial warm up, you should use a
mid to low blower speed for maximum
effectiveness. When operating in
automatic mode (when equipped) the
climate control unit determines the
appropriate blower speed for existing
conditions.

FUEL SHUTOFF
In the event of a moderate to severe
collision, this vehicle is equipped with a
fuel pump shut-off feature that stops the
flow of fuel to the engine. Not every impact
will cause a shut-off.
After an accident, if the engine cranks but
does not start, this switch may have been
activated.
This switch is located on the passenger
’s
side of the instrument panel. Open the
front passenger door and remove the small
access panel The switch has a red button on top of it.
To reset the switch:
1. Turn the ignition off.
2. Check the fuel system for leaks. 3. If no leaks are apparent, reset the
switch by pushing in on the reset
button.
4. Turn the ignition on.
5. Wait a few seconds and return the key
to off.
6. Make another check for leaks.
Running Out Of DEF (Diesel
Exhaust Fluid)
If your vehicle runs out of DEF, it will enter
into a speed limited mode and can also
enter into an idle-only mode. Normal
vehicle operation will not resume until DEF
is refilled. See Selective Catalytic
Reduction System (page 21).
Contact roadside assistance for help in
finding a retailer that sells DEF. See the
Customer Assistance chapter in the
Owner ’s Manual for more information.
JUMP STARTING THE VEHICLE WARNINGS
The gases around the battery can
explode if exposed to flames, sparks,
or lit cigarettes. An explosion could
result in personal injury or vehicle damage. Batteries contain sulfuric acid which
can burn skin, eyes and clothing, if
contacted.
Use only an adequate-sized cable
with insulated clamps.
Preparing Your Vehicle
Note:
Do not attempt to push-start your
automatic transmission vehicle. Automatic
transmissions do not have push-start

ENGINE COOLANT CHECK
Checking the Engine Coolant
When the engine is cold, check the
concentration and level of engine coolant
at the intervals listed in the scheduled
maintenance chapter. See Scheduled
Maintenance (page 59). Note:
Make sure that the level is between
the MIN and MAX marks on the coolant
reservoirs.
Note: Coolant expands when it is hot. The
level may extend beyond the MAX mark
Note: If the level is at the MIN mark, below
the MIN mark, or empty, add coolant
immediately. See
Adding Engine Coolant
in this chapter.
Note: The coolant concentration should be
maintained within 48% to 50%, which
equates to a freeze point between -30 °F
(-34 °C) and -34 °F (-37 °C).
Note: For best results, the coolant
concentration should be tested with a
refractometer such as Rotunda tool
300-ROB75240 available from your dealer.
Ford does not recommend the use of
hydrometers or coolant test strips for
measuring coolant concentrations.
Note: Automotive fluids are not
interchangeable. Do not use engine coolant
or antifreeze or windshield washer fluid
outside of its specified function and vehicle
location.
Adding Engine Coolant WARNINGS
Do not add engine coolant when the
engine is hot. Steam and scalding
liquids released from a hot cooling
system can burn you badly. Also, you can
be burned if you spill coolant on hot engine
parts. Do not put engine coolant in the
windshield washer fluid container. If
sprayed on the windshield, engine
coolant could make it difficult to see
through the windshield.

Super Duty (TFA) , enUSA Maintenance

Coolant Change
At specific mileage intervals, as listed in
the scheduled maintenance information,
the coolant should be changed. The
optional information display, if equipped,
will also display the message COOLANT
CHANGE REQUIRED at this time.
See Capacities and Specifications
(page 55). for the proper coolant.
Engine-driven Cooling Fan (Fan
Clutch)
Your vehicle is equipped with an engine
driven cooling fan drive (also called a fan
clutch). This fan drive changes the fan
speed to match the vehicle ’s changing
cooling air flow requirements. Fan speed,
fan noise level and fuel consumption all
will increase based on the driving
conditions that include trailer towing, hill
climbing, heavy loads, high speed and high
ambient temperature, individually or in
combination.
The fan drive is designed to provide the
minimum fan speed (and resulting
minimum fan noise and fuel consumption)
required to meet the ever changing vehicle
cooling air flow requirements. You will hear
the amount of fan noise increasing and
decreasing as the engine power
requirements and vehicle driving conditions
change as you drive. This is to be expected
as being normal to the operation of your
vehicle. High levels of fan noise might also
be heard when your engine is first started,
and should normally decrease after driving
for a short time. CHANGING THE ENGINE AIR
FILTER
Air Filter Restriction Gauge WARNING
To reduce the risk of vehicle damage
and/or personal burn injuries do not
start your engine with the air filter
removed and do not remove it while the
engine is running. Note:
Operating your vehicle in heavy
snowfall or extreme rain conditions may
allow excessive amounts of snow or water
into the air intake system. This could plug
or soak the air filter that could cause the
engine to lose power or shut down. The restriction gauge, located on the upper
housing of the air filter assembly, measures
the vacuum inside the air filter. The more
the air filter is restricted (dirty, clogged),
the higher the vacuum reading.
Check the air filter restriction gauge
whenever you open the hood to perform
general engine maintenance or at least
every 7,500 miles (12,000 km). If you
operate your vehicle in extremely dusty
conditions, check and reset the gauge at
least every 500 miles (800 km), or two
weeks, whichever comes first. Change the
