2012 FORD SUPER DUTY light

the DFCM filter should be changed at the recommended service interval
or when indicated by the message centerLOW FUEL PRESSURE
message. Refer to thescheduled maintenance informationin this
supplement for more information.
The DFCM should be drained at regular intervals or when indicated by
the message center message and water in fuel indicator light. SeeFuel
filter/water separatorin theMaintenance and Specificationschapter.
The fuel injection system is controlled through the powertrain control
module (PCM).
Fuel is drawn from the fuel tank by a frame-mounted electric fuel pump
located inside the DFCM and provides pressurized fuel to the engine.
The fuel pump contains a pressure relief valve for overpressure
protection in the event of restricted flow.
Engine protection mode
Ford diesel engines are equipped with engine protection and emission
control systems. These systems monitor critical temperatures and
pressures, and modify engine operation accordingly. These features are
intended to modify engine performance characteristics. If these modified
engine performance characteristics persist for an extended period or the
service engine soon
or powertrain malfunction/reduced
power/electronic throttle control light
is illuminated, seek service
from your authorized dealer.
Lubrication system
It is important to change the engine oil at the recommended service
intervals to maintain oil viscosity. Extending the oil and filter change
interval beyond the recommended interval can negatively affect engine
performance, fuel economy and engine life. Refer toEngine oilin the
Maintenance and Specificationschapter.
Fast start glow plug system
The diesel engine glow system consists of:
•eight glow plugs (one per cylinder)
•the glow plug control module (GPCM)
•engine coolant temperature (ECT) sensor
•barometric pressure (BARO) sensor
•environmental temperature sensor

Water in fuel:
During refueling, it is possible for
water-contaminated diesel fuel to be
pumped into your tank. Your
vehicle’s fuel system is equipped
with a fuel filter/water separator to remove water from the fuel. The
water in fuel light will illuminate when the DFCM has a significant
quantity of water in it.
If the light illuminates when the engine is running, stop the vehicle as
soon as safely possible, shut off the engine, then drain the DFCM. Refer
toFuel filter/water separatorin theMaintenance and Specifications
chapter of this supplement for the drain procedure. Allowing water to
stay in the system could result in extensive damage to, or failure of, the
fuel injection system.
Note:Air will enter into the fuel system if the DFCM is drained while
the system is running. The engine will not operate properly if air enters
the system.
WARNING:Do not drain the DFCM while the engine is running.
Fuel may ignite if the separator is drained while the engine is
running or the vehicle is moving.
Low/contaminated diesel exhaust fluid:
With the key in the on position, this
light will illuminate if the exhaust
fluid is contaminated and/or low.
SeeDiesel exhaust fluidin the
Maintenance and Specifications
chapter for more information.

COLD WEATHER OPERATION
Changing to a lighter grade engine oil also makes starting easier under
these conditions. Refer toEngine oil specificationsin theMaintenance
and Specificationschapter of this supplement.
Diesel fuel is adjusted seasonally for cold temperatures. Diesel fuel which
has not been properly formulated for the ambient conditions may form
wax crystals which can clog the fuel filters. At temperatures below 20°F
(–7°C), if the engine starts, stalls after a short time, and then will not
restart, the fuel filter(s) may be clogged. For best results in cold
weather, use a diesel fuel which has been formulated for the ambient
conditions. 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/system. Use the proper
anti-gel & performance improver product as listed in theMaintenance
product specifications and capacitiessection in theMaintenance and
Specificationschapter.
Your vehicle is equipped with a diesel fuel conditioner module (DFCM)
which 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, it is recommended that the fuel level in your
tank should not be allowed to drop below
14full. This will help prevent
air from entering the fuel system and stalling the engine.
Your vehicle is equipped with a an SCR system which uses diesel exhaust
fluid (DEF) to operate properly. DEF must be replenished at certain
intervals. When filling the vehicle’s DEF tank in cold weather, special
care must be taken to prevent damage to the DEF tank. For proper cold
weather fill procedure, seeSelective Catalytic Reduction (SCR) System
in theMaintenance and Specificationschapter.
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 will decrease due to the activation of PCM-controlled
sound reduction features.
If your vehicle is operated in a heavy snow storm or blowing snow
conditions, the engine air induction may become partially clogged with
snow and/or ice. 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. Ensure the foam filter is installed correctly in

ENGINE
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal. When washing:
•Take care when using a power washer to clean the engine. The
high-pressure fluid could penetrate the sealed parts and cause
damage.
•Do not spray a hot engine with cold water to avoid cracking the
engine block or other engine components.
•Spray MotorcraftEngine Shampoo and Degreaser (ZC-20) on all
parts that require cleaning and pressure rinse clean.
•Never wash or rinse the engine while it is running; water in the
running engine may cause internal damage.
•Cover the highlighted areas to prevent water damage when cleaning
the engine.

SCHEDULED MAINTENANCE
The scheduled maintenance services in thescheduled maintenance
informationof this supplement are required because they are
considered essential to the life and performance of your vehicle.
Use only recommended fuel, lubricants, fluids and service parts
conforming to Ford specifications. Motorcraftparts are designed and
built for best performance in your vehicle.
FUEL REQUIREMENTS - CHOOSING THE RIGHT FUEL: VEHICLES
OPERATED WHERE ULTRA LOW SULFUR DIESEL FUEL IS
REQUIRED (UNITED STATES/CANADA/PUERTO RICO/U.S. VIRGIN
ISLANDS AND OTHER LOCALES)
Use only Ultra Low Sulfur (15 ppm Sulfur Maximum) number 1-D
or 2-D diesel fuel (also known as ULSD) in your 6.7L diesel
engine.The engine and exhaust system were designed to only use this
fuel. Look for theULTRA-LOW SULFUR HIGHWAY DIESEL FUEL
(15 ppm Sulfur Maximum)label on fuel pumps when purchasing your
fuel.
Using low sulfur diesel fuel (16-500 ppm) or high sulfur diesel
fuel (greater than 500 ppm) in a diesel engine designed to use
only Ultra Low Sulfur Diesel fuel will cause certain emission
components to malfunction which may also cause the service
engine soon
light to illuminate indicating an emissions-
related concern.
Diesel fuel is adjusted seasonally for cold temperature. For best results
at temperatures below 20°F (-7°C), it is recommended to use a diesel
fuel which has been seasonally adjusted for the ambient conditions. See
Cold weather operationin theDrivingchapter of this supplement.
FUEL REQUIREMENTS - CHOOSING THE RIGHT FUEL: VEHICLES
OPERATED WHERE ULTRA LOW SULFUR DIESEL FUEL IS NOT
REQUIRED
For the engine to operate reliably on low-sulfur or high-sulfur diesel fuel,
the engine must be a factory built high-sulfur engine (available as a
dealer order option for select markets) or a ULSD (ultra low sulfur
diesel) fuel configured engine that has been retrofitted for high-sulfur
diesel fuel using Ford Motor Company dealer service parts. Failure to use
retrofit components other than those available through your authorized
dealer will result in engine coolant system damage, engine overheating,
SCR and/or DPF damage and possible base engine damage.

5. Once the level in the DEF bottle
has stopped dropping, return the
container to the vertical position
slightly below the DEF filler port
and let any DEF drain out of the
spout. DO NOT try to continue to
add DEF to the tank by shaking or
repositioning the container to
induce flow. This may cause spilling
and overfill the tank. Overfilling the
DEF tank can cause damage to the
tank.
6. Once the spout has drained, remove the spout from the DEF filler
port and install the blue cap on the DEF filler port.
7. Remove the spout from the DEF container and install the cap back on
the bottle.
8. If the container is empty, discard the empty container, or recycle if
possible. If there is DEF left in the container, retain it for later use. The
spout is re-useable; after use, rinse it with clean water and store the
spout to ensure it is kept clean. Do not use the DEF spout with any
other chemicals.
9. Wipe away any DEF that has spilled on painted surfaces with water
and a damp cloth.
•DEF filling station nozzle fill:
Filling the DEF tank using a nozzle is similar to a normal fuel fill. The
nozzle will shut off automatically when the tank is full. Do not continue
to fill the tank as this may cause spilling and overfill the tank which can
cause damage.
Note:Some filling station nozzles may prevent filling of your DEF tank
due to a magnetic mechanism in the nozzle. This is not a problem with
your vehicle. To refill your tank either locate another filling station or
use a bottle to refill the tank.
Filling the DEF tank in cold climates
DEF will freeze below 12°F (-11°C); however, your vehicle is equipped
with an automatic preheating system which allows the DEF system to
operate below 12°F (-11°C). When the vehicle is not in operation for an
extended period of time with temperatures at or below 12°F (-11°C), the
DEF tank could freeze. If the tank is OVERFILLED and freezes, it could
be damaged, therefore DO NOT OVERFILL.

To prevent overfilling of the DEF tank when filling with a bottle, Ford
recommends using MotorcraftDEF. Additionally, if the message center
indicatesEXHAUST FLUID UNDER 1/2 FULL, you should only add a
MAXIMUM of 2 gallons (6.7L) of DEF to the tank to prevent freeze
damage due to overfilling. If the message center indicatesEXHAUST
FLUID LEVEL OK, do not add DEF.
Contaminated DEF or inoperative SCR system
SCR systems are sensitive to
contamination of the DEF. USE
ONLY API or ISO 22241 CERTIFIED
DIESEL EXHAUST FLUID. If the
SCR becomes contaminated or
inoperative, the DEF light will
illuminate and exhaust fluid system
fault messages will appear in the
message center.
Continued driving without replacing DEF or having the SCR system
repaired will result in the following actions as required by the California
Air Resources Board (CARB) and /or U.S. Environmental Protection
Agency (EPA):
•Within a certain number of miles (kilometers) to empty, speed will be
limited upon restart. Prior to this occurring a message will appear in
the message center.
•Further vehicle operation without replacing contaminated DEF will
cause the engine to enter an idle-only condition. This will only occur
upon vehicle refueling, vehicle idling in park for 1 hour, or engine
shutdown for 10 minutes or more and will be indicated by a message
in the message center indicating required actions to resume normal
operation.
For either vehicle speed limiting or idle-only condition, normal vehicle
operation will resume when the contaminated system is repaired.To
service a contaminated or inoperative system, see your
authorized dealer.
DEF guidelines and information
•Use only DEF that carries the trademark: American Petroleum
Institute (API) certified DEF or ISO 22241.
•Do not put DEF in the diesel fuel tank.
•Do not overfill the DEF tank.
•Do not re-use the DEF container or nozzle once it is emptied.
