2012 FORD SUPER DUTY service

When the engine control module detects that the DPF is nearly full of
particulates and that the vehicle is not being operated in a manner to
allow effective automatic cleaning, the message center will display
DRIVE TO CLEAN EXHAUST FILTERfor base message center and
Drive to Clean Exhaust Systemfor the optional message center,
guiding the vehicle operator to drive in order to clean the DPF. If the
vehicle is operated in a manner to allow effective automatic cleaning, the
message center will display a cleaning exhaust filter message, which is
the normal regeneration process. SeeMessage centerin theInstrument
Clusterchapter of theOwner Guidefor more information.
Note:You can also choose OCR to clean the exhaust system at this
point. SeeHow to start operator commanded regeneration (OCR)
later in this chapter.
If the operator is not able to drive in manner that allows effective
automatic cleaning (active regeneration) or the operator instead wishes
to perform regeneration of the DPF (cleaning) while at idle (stationary),
then OCR (operator commanded regeneration) will need to be
performed. SeeOperator commanded regeneration (OCR)following.
Note:Do not disregard theDRIVE TO CLEAN EXHAUST FILTERor
Drive to Clean Exhaust Systemmaintenance message for extended
periods of time. Failure to perform active or operator commanded
regeneration (OCR) (if equipped) when instructed may result in a
clogged DPF. If your DPF fills beyond what can be safely regenerated,
active regeneration and OCR will be disabled. This could cause
irreversible damage to the DPF, requiring service and possible
replacement that may not be covered by your warranty.
Operator commanded regeneration (OCR) (if equipped)
If your vehicle is operated with significant stationary operation, passive
and active regeneration may not sufficiently clean the DPF system. OCR
allows you to manually start regeneration of the diesel particulate filter
(DPF) at idle (while stationary) to clean the DPF. If you are not sure
whether your vehicle is equipped with this feature, contact your
authorized dealer.
When to perform OCR
Use the OCR feature when theDRIVE TO CLEAN EXHAUST FILTER
message appears in the message center 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 DPF while the vehicle is idle (stationary).

OCR precautions and safe exhaust position
WARNING:Failure to comply with the following instructions for
operator commanded regeneration (OCR) may result in fire,
serious injury, death and/or property damage.
Before you start OCR, observe/do the following:
•Place the vehicle in P (Park) with the parking brake set on stable,
level ground.
•The vehicle must not be parked in a structure.
•The 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 such
as: paper, leaves, petroleum products, fuels, plastics and other dry
organic material, such as grass.
•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. SeeExhaustunder the
Cleaningchapter for more information.
How to start operator commanded regeneration (OCR)
WARNING:Stay clear of exhaust tip during regeneration. You or
others can be burned.
Note:OCR will not be allowed until DPF load percentage has reached at
least 80%. The DPF load percentage will fluctuate up and down when
driving your vehicle due to active and passive regenerations.
Note:OCR will not be allowed to operate if the service engine soon
light
is illuminated
Note:During the use of OCR, you may observe a light amount of white
smoke. This is normal.
Note:During stationary PTO operation, OCR will change the engine speed
to 2,000 or 2,400 rpm (depending on vehicle application), therefore it is
recommended you exit PTO mode before starting OCR. During mobile PTO
use, OCR is not necessary; regeneration will function normally.

3. Once OCR 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
OCR 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 DPF, ambient
temperature, and altitude, OCR may last from 10 to 25 minutes.

eliminated, but the exhaust system and exhaust gas may still be hot. If
the vehicle is shut off during OCR, 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/maintenance
Over time a slight amount of ash will build up in the DPF which is not
removed during the regeneration process. The DPF 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
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
engine/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 oxidation catalyst/DPF system a service
light
orwill be set by the engine control system to inform
you to bring the vehicle into your authorized dealer for service.
Resonator/Tailpipe assembly maintenance
The diesel resonator tail-pipe assembly is a uniquely functioning device
that accompanies the Oxidation Catalyst/DPF assembly. The 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 the vehicle. It also is designed to help control the temperature of
the exhaust during DPF 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. The holes need to be kept 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 vehicle should
help keep holes clean and clear of debris or foreign material.
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 and/or engine. These actions may
also affect the vehicle’s warranty. See theWarranty Guidefor more
information.
Maintenance and Specifications
59
2012 Diesel(67l)
Supplement(supplement), 1st Printing
Arabic_(LHD)(gc_lhd)

WARNING: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.
WARNING: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 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.
EMISSION CONTROL SYSTEM(S) LAWS
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.
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.
Tampering with emissions control systems (including related sensors and
the diesel exhaust fluid (DEF) injection system) can result in reduced
engine power and the illumination of the service engine soon light

NOISE EMISSIONS WARRANTY, PROHIBITED TAMPERING ACTS
AND MAINTENANCE
On January 1, 1978, Federal regulation became effective governing the
noise emission on trucks over 10,000 lbs. (4,536 kg) GVWR (Gross
Vehicle Weight Rating). The following statements concerning prohibited
tampering acts and maintenance, and the noise warranty found in the
Warranty Guide, are applicable to complete chassis cabs over
10,000 lbs. (4,536 kg) GVWR.
Tampering with noise control system prohibited
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, so as
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, 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/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.

GENERAL MAINTENANCE INFORMATION
Why maintain your vehicle?
This guide describes the scheduled maintenance required for your vehicle.
Carefully following this schedule helps protect against major repair
expenses resulting from neglect or inadequate maintenance and may also
help to increase the value of your vehicle when you sell or trade it.
It is your responsibility to see that all scheduled maintenance is performed
and that the materials used meet Ford engineering specifications as
identified in theMaintenance and Specificationschapter. Failure to
perform scheduled maintenance specific in this guide will invalidate
warranty coverage on parts affected by the lack of maintenance. Be sure
receipts for completed maintenance are kept with the vehicle and
confirmation of the work performed is always recorded in this guide.
Your Ford dealer has factory-trained technicians who can perform the
required maintenance using genuine Ford parts. They are committed to
meeting your service needs and to assuring your continuing satisfaction.
Protecting your investment
Maintenance is an investment that will pay dividends in the form of
improved reliability, durability and resale value. To ensure the proper
performance of your vehicle and its emission control systems, it is imperative
that scheduled maintenance be completed at the designated intervals.
Your vehicle is equipped with the Intelligent Oil Life Monitor™ system
which displays a message in the message center at the proper oil change
service interval; this interval may be up to one year or 10,000 miles
(16,000 km). When ENGINE OIL CHANGE DUE or OIL CHANGE
REQUIRED appears in the message center display, it’s time for an oil
change; the oil change must be done within two weeks or 500 miles
(800 km) of the OIL CHANGE REQUIRED message appearing. The
Intelligent Oil Life Monitor™ must be reset after each oil change; refer to
theInstrument Clusterchapter.
If your message center is prematurely reset or becomes inoperative, you
should perform the oil change interval at six months, 5,000 miles
(8,000 km) or 200 engine hours from your last oil change.
Your vehicle is very sophisticated and built with multiple complex
performance systems. Every manufacturer develops these systems using
different specifications and performance features. That’s why it’s
important to rely upon your Ford dealership to properly diagnose and
repair your vehicle.
