How to Use Diagnostic Information
DTC and Symptom Charts
Module DTC Charts are used to begin and direct the diagnosis of a DTC. Symptom Charts contain
concern symptoms and direct solutions either in the chart or in a linked Diagnostic Routine. Both DTC
and Symptom Charts may provide the solution within the chart, or provide a link to the appropriate
Diagnostic Routine.
In some sections, the Symptom Chart is preceded by a Preliminary Inspection which must be followed
prior to using the Symptom Chart
Using Module DTC Charts
This Workshop Manual contains diagnostics for DTCs set by vehicle modules. Driveability and emission
DTCs are covered in the separate Powertrain Control/Emissions Diagnosis (PC/ED) manual. If a PCMset DTC is not listed in the Workshop Manual, it is serviced in the Powertrain Control/Emissions
Diagnosis (PC/ED) manual.
DTC diagnostics are found in both on-line and printed publications and are used as follows:
On-line publications: Using the left side menu, click on the Master DTC Chart link to view the
vehicle module DTC charts. Each module has a chart with links or in-chart solutions for all DTCs
diagnosed in the Workshop Manual.
Printed publications: Use the DTC index in the rear of the book.
Diagnostic Methods
Diagnostic Methods provides information to support diagnosing Ford vehicles. Diagnostic strategies,
diagnostic tool support information, and advanced circuit testing methods are included. REFER to
Diagnostic Methods .
Diagnostic Routines
Diagnostic Routines provide information to determine the root cause of concerns addressed in either a
DTC Chart or Symptom Chart. Each Diagnostic Routine contains:
Diagnostic Overview
Wiring Diagram References (as applicable)
Normal Operation and Fault Conditions
Visual Inspection and Diagnostic Pre-checks
Tool Table (as applicable)
Material Table (as applicable)
Pinpoint Test Steps
Component Tests
Component Tests are used to separately analyze a single common component in a system. The test will
determine if the part is functioning correctly.
Mechanical Procedures Such As Removal and Installation
Reuse Of Fasteners, Seals, Or Gaskets
The following is a list of assumptions made in the reuse of fasteners, seals, or gaskets.
Seals and gaskets must be replaced unless otherwise specified.
Standard fasteners are reused unless otherwise specified.
Fasteners with self-locking features must be replaced unless otherwise noted. Reminder text may
or may not be included with the procedure step. Examples of fastener coatings or fasteners with
mechanical locking (with the locking features highlighted yellow) are shown in illustration 1.
Torque to yield bolts (bolts with more than one stage of tightening torque and a final torque angle
specification) must be discarded and new torque to yield bolts installed unless otherwise stated
within the procedure.
Illustration 1 - self-locking coatings or locking feature are highlighted yellow
Graphics
Illustrations in this manual may be used to replace written step instructions. Color-coding (see color
scheme in this document) is used to communicate the required step action or actions. Service action
icons (see Symbols Glossary ) are used to add additional information regarding the required action.
The color scheme in a step graphic (an illustration used in removal or installation steps) indicates
servicing information as follows:
Fasteners (including panel retainers) or electrical connectors — Magenta (Purple)
Target component that is to be removed — Blue
Components that must be removed prior to the target component shown in blue — Brown
or Green
Components placed aside for access, but not removed; highlighted areas such as
inspection areas, adjustments or measurements — Yellow
Essential Special Service Tools (ESSTs) and other tools — Pale Blue
Chemical or Sealer apply areas — Alternating blue and white dashes (see illustration 4)
Sectioned or cut-away areas — Red
Remaining components — Grey
Callouts in graphics indicate removal (or tightening) order, or identify individual instructions in substeps
of the same number (such as different torque values).
Arrows containing x numbers (Illustration 2) indicate the number of identical fasteners or connectors to
be removed or installed in the graphic.
In Illustration 2, two identical fasteners are indicated by the x2 arrow, with another arrow illustrating a
third fastener of a different type. Because the different fasteners require different torques, callouts are
used to identify those two torque values in the associated step text. The hose clamp is another fastener
to be removed. The yellow coloring of the hose indicates it is to be moved aside (not removed).
The following written steps would be necessary if the illustration did not have color coding:
1. Remove the engine oil pipe fastener at the engine connection.
2. Remove the two engine oil pipe fasteners from the turbocharger and remove the pipe.
3. Remove the air inlet hose from the turbocharger and position aside.
Illustration 2
Hidden fasteners, such as panel retainers, are identified in the illustration by a magenta disc. An inset
detail view illustrating the fastener type may be included (Illustration 3).
Illustration 3 — Note motion arrow at panel bottom; it indicates to lift panel up, then move inward
to remove
Symbols
Symbols may be used inside graphics or in the text area to communicate service actions. The following
examples demonstrate the use of some of these symbols. REFER to Symbols Glossary for a complete
symbols list with explanations.
In the Illustration 4 example, service action symbols are shown as used to direct the application of
sealer, lubricant, weight, tape or cleaning detergent to a component. In this example a bead diameter of
“xx” millimeters is prescribed. The blue and white dashes indicate where the material is applied.
Illustration 4
Illustration 5 is an example of location symbols used to show the location of a component or system
within the vehicle.
Illustration 5
Illustration 6 shows how gearshift lever or selector lever position symbols may be used to indicate the
gearshift lever or selector lever position required. The required Essential Special Service Tool to align
the shift mechanism is shown in pale blue and identified by ESST number.
Illustration 6
Callouts or arrows may be used to identify components for supporting special information, such as a
required sequence or to indicate a number of identical components. Illustration 7 shows a removal order
in the top graphic and the bottom graphic indicates 12 identical bolts.
Illustration 7
Standard tool symbols direct the use of standard tools to perform a service action, such as the cutting of
carpet shown in Illustration 8. Tool symbols may include dimensional values (for example, a drill with a
specified diameter).

DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 08/12/2011
Safety Warnings
Heating, Ventilation and Air Conditioning Safety Warnings
WARNING: Take the following precautions when repairing an air conditioning system
containing R-134a:
Always wear safety goggles.
Avoid contact with liquid refrigerant R-134a. R-134a vaporizes at approximately -25°C (-13°
F) under atmospheric pressure and will freeze skin tissue.
Never allow refrigerant R-134a gas to escape in quantity in an occupied space. It will
displace the oxygen needed to support life.
Never use a torch in an atmosphere containing R-134a gas. R-134a is non-toxic at all
normal conditions, but it decomposes when exposed to high temperatures such as a torch
flame. During decomposition it releases irritating and toxic gasses (as described in the
MSDS sheet from the manufacturer). Decomposition products are hydrofluoric acid,
carbon dioxide and water.
Failure to follow these instructions may result in serious personal injury.
WARNING: Before disconnecting any heater water hoses, shut OFF the engine and wait
until engine is fully cool. Failure to comply with this warning may result in serious injury or burns
from hot liquid escaping from the engine cooling system.
WARNING: Use extreme care and observe all safety and service precautions related to the
use of refrigerants as outlined on refrigerant tank and on recovery and charging equipment.
Failure to follow these instructions may result in serious personal injury.
Battery System Service Warnings
WARNING: Always disconnect the battery ground cable at the battery before disconnecting
the starter motor battery terminal lead. If a tool is shorted at the starter motor battery terminal,
the tool can quickly heat enough to cause a skin burn. Failure to follow this instruction may
result in serious personal injury.
WARNING: Before carrying out maintenance on the starting system, disconnect the battery
ground cable from the frame to completely isolate the starter from the dual frame-mounted
batteries. Failure to follow this instruction may result in serious personal injury.
WARNING: Batteries contain sulfuric acid and produce explosive gases. Work in a wellventilated area. Do not allow the battery to come in contact with flames, sparks or burning
substances. Avoid contact with skin, eyes or clothing. Shield eyes when working near the battery
to protect against possible splashing of acid solution. In case of acid contact with skin or eyes,
flush immediately with water for a minimum of 15 minutes, then get prompt medical attention. If
acid is swallowed, call a physician immediately. Failure to follow these instructions may result in
serious personal injury.
WARNING: Always lift a plastic-cased battery with a battery carrier or with hands on
opposite corners. Excessive pressure on the battery end walls may cause acid to flow through
the vent caps, resulting in personal injury and/or damage to the vehicle or battery.
WARNING: Do not get underneath the frame-mounted battery when disconnecting or
connecting the auxiliary battery safety straps. The battery is heavy and could fall. Failure to
follow this instruction may result in serious personal injury.
WARNING: Battery posts, terminals and related accessories contain lead and lead
components. Wash hands after handling. Failure to follow these instructions may result in
serious personal injury.
Brake System Service Warnings

specification. Additionally, do not use brake fluid that has been previously drained. Following
these instructions will help prevent system contamination, brake component damage and the
risk of serious personal injury.
WARNING: Do not use any brake fluid other than DOT 3 for Hydro-Boost® and DOT 4 for
Hydro-Max®. Incorrect fluid may result in permanent damage to brake components and an
inoperative brake system. Failure to follow these instructions may result in serious injury to
vehicle occupant(s).
WARNING: Do not breathe dust or use compressed air to blow dust from storage
containers or friction components. Remove dust using government-approved techniques.
Friction component dust may be a cancer and lung disease hazard. Exposure to potentially
hazardous components may occur if dusts are created during repair of friction components,
such as brake pads and clutch discs. Exposure may also cause irritation to skin, eyes and
respiratory tract, and may cause allergic reactions and/or may lead to other chronic health
effects. If irritation persists, seek medical attention or advice. Failure to follow these instructions
may result in serious personal injury.
WARNING: Remove air pressure from the air brake system prior to servicing the system.
Attempting to service the air brake system while it is under pneumatic pressure may result in
serious injury from unexpected hose whip, component movement or component propulsion.
WARNING: Always install new brake shoes or pads at both ends of an axle to reduce the
possibility of brakes pulling vehicle to one side. Failure to follow this instruction may result in
uneven braking and serious personal injury.
Body and Frame Service Warnings
WARNING: Always refer to Material Safety Data Sheet (MSDS) when handling chemicals and
wear protective equipment as directed. Examples may include but are not limited to respirators
and chemically resistant gloves. Failure to follow these instructions may result in serious
personal injury.
WARNING: Always wear protective equipment including eye protection with side shields,
and a dust mask when sanding or grinding. Failure to follow these instructions may result in
serious personal injury.
WARNING: On vehicles equipped with Safety Canopy® options, prior to carrying out any
sectioning repairs near the roof line or sail panel areas of the vehicle, remove the Safety
Canopy® module and related components. Failure to comply may result in accidental
deployment or damage to the Safety Canopy®. Refer to Section 501-20B . Failure to follow these
instructions may result in serious injury to technician or vehicle occupant(s).
WARNING: Do not cut or grind body side components within 50 mm (1.96 in) of restraint
anchoring points. Welding within 50 mm (1.96 in) of restraint anchoring points may result in
incorrect operation of restraint devices. For additional restraints anchoring location information,
refer to Section 501-20A and Section 501-20B . Failure to follow these instructions may result in
serious injury to vehicle occupant(s).
WARNING: Do not carry out body side sectioning repairs in areas of laser welds. Factory
laser welds cannot be duplicated with conventional welding equipment and structural integrity
may be compromised. Failure to follow this instruction may result in serious injury to vehicle
occupant(s).
WARNING: Do not carry out body side sectioning repairs in areas of door hinge or striker
anchoring points. Welding within 50 mm (1.96 in) of door hinge or striker locations may
compromise structural integrity during a collision. Failure to follow these instructions may result
in serious injury to vehicle occupant(s).
WARNING: Invisible ultraviolet and infrared rays emitted in welding can injure unprotected
eyes and skin. Always use protection such as a welder's helmet with dark-colored filter lenses of
the correct density. Electric welding will produce intense radiation, therefore, filter plate lenses
of the deepest shade providing adequate visibility are recommended. It is strongly recommended
that persons working in the weld area wear flash safety goggles. Also wear protective clothing.
Failure to follow these instructions may result in serious personal injury.
WARNING: If a vehicle has been in a crash, inspect the restraints control module (RCM) and
the impact sensor (if equipped) mounting areas for deformation. If damaged, restore the
mounting areas to the original production configuration. A new RCM and sensors must be
installed whether or not the air bags have deployed. Failure to follow these instructions may
result in serious personal injury or death in a crash.
WARNING: Do not permanently remove the trailer hitch. The trailer hitch is an integral part
of the vehicle frame. Always reinstall the hitch before delivery of the vehicle to the customer.
Failure to follow this instruction may compromise vehicle crash integrity and increase the risk of
personal injury in a rear end collision.

WARNING: Always install new brake shoes or pads at both ends of an axle to reduce the
possibility of brakes pulling vehicle to one side. Failure to follow this instruction may result in
uneven braking and serious personal injury.
WARNING: Do not paint any air bag module trim covers or deployment doors. Paint may
cause the air bag to deploy incorrectly. Failure to follow this instruction may increase the risk of
serious personal injury or death in a crash.
Tire and Wheel Service Warnings
WARNING: Tires degrade over time depending on many factors such as weather, storage
conditions, and conditions of use (load, speed, inflation pressure, etc.) the tires experience
throughout their lives. In general, new tires should be installed after 6 years regardless of tread
wear. However, heat caused by hot climates or frequent high loading conditions may accelerate
the aging process and may require new tires to be installed more frequently. You should install a
new spare tire when you install new road tires or after six years even if it has not been used.
WARNING: Replacement wheels must be equivalent to the original equipment wheels in:
load carrying capacity.
diameter, width and offset.
pilot hole and bolt circle.
Combined load carrying capacity of replacement wheels for a given axle, must be equal to or
greater than that axle's gross axle weight rating (GAWR) identified on the vehicle's Safety
Compliance Certification label. All other specifications should be evaluated by measurement of
both the original wheel and the replacement wheel. If specifications are not equivalent, the safety
and handling of the vehicle may be degraded, which may result in serious injury to the vehicle
occupant(s).
WARNING: Never inflate a tire that has been run flat without first removing the tire from the
wheel to inspect for damage. A damaged tire can fail during inflation. Failure to follow this
instruction may result in serious personal injury.
WARNING: Do not hit the wheel or tire with a metallic hammer. This action may damage the
wheel or tire, resulting in tire or wheel failure. Failure to follow this instruction may result in
serious personal injury to the technician or vehicle occupant(s).
WARNING: When a wheel is installed, always remove any corrosion, dirt or foreign material
present on the mounting surface of the wheel and the mounting surface of the wheel hub, brake
drum or brake disc. Make sure that any fasteners that attach the rotor to the hub are secured so
they do not interfere with the mounting surfaces of the wheel. Failure to follow these instructions
when installing wheels may result in the wheel nuts loosening and the wheel coming off while
the vehicle is in motion, which could result in loss of control, leading to serious injury or death to
vehicle occupant(s).
WARNING: Inflating tires to pressures that exceed maximum tire inflation rating on tire
sidewall may result in tire failure and serious personal injury to the technician or vehicle
occupant(s).
WARNING: Only use replacement tires that are the same size, load index, speed rating and
type (such as P-metric versus LT-metric or all-season versus all-terrain) as those originally
provided by Ford. The recommended tire and wheel size may be found on either the Safety
Compliance Certification Label or the Tire Label, which is located on the B-pillar or edge of the
driver's door. If the information is not found on these labels, consult a Ford dealer. Use of any
tire or wheel not recommended by Ford can affect the safety and performance of the vehicle,
which could result in an increased risk of loss of vehicle control, vehicle rollover, personal injury
and death. Additionally, the use of non-recommended tires and wheels could cause steering,
suspension, axle or transfer case/power transfer unit failure.
WARNING: Do not mount tube-type tires on tubeless wheels or tubeless tires on tube-type
wheels. Incorrect combinations could result in tire separation from wheel and may result in
serious injury to vehicle occupant(s).
WARNING: Cracked wheels can be dangerous. Deflate tires on cracked wheels prior to
removal of wheels from the vehicle. Failure to follow this instruction may result in serious
personal injury.
WARNING: Retighten wheel nuts within 160 km (100 mi) after a wheel is reinstalled. Wheels
can loosen after initial tightening. Failure to follow this instruction may result in serious injury to
vehicle occupant(s).
WARNING: Retighten wheel nuts within 160 km (100 mi) after a wheel is reinstalled. For dual
rear wheel (DRW) only, a second retightening is required within 800 km (500 mi). Wheels can
loosen after initial tightening. Failure to follow this instruction may result in serious injury to
vehicle occupant(s).
WARNING: Always match the tire size to the wheel size during assembly. Incorrect
matching can result in tire bead damage or tire separation from the wheel. Failure to follow this
instruction may result in serious personal injury to technician or vehicle occupant(s).
WARNING: Keep eyes away from valve stem when deflating tires. Reduce air pressure in
tire as much as possible by pushing in valve core plunger prior to removing the core. Escaping
air can carry particles that can injure the eyes. Failure to follow these instructions may result in
serious personal injury.
WARNING: Never use wheels different than the original equipment. Additionally, never use
wheel nuts different than the original equipment. Failure to follow these instructions may result
in damage to the wheel or mounting system. This damage could cause the wheel to come off
while the vehicle is being driven, which could result in serious personal injury or death to vehicle
occupant(s).
WARNING: Do not weld or peen wheels. A wheel needing such repairs must have a new
wheel installed. Failure to follow these instructions may result in wheel failure and serious
personal injury.
WARNING: The tire pressure monitoring system (TPMS) sensor battery may release
hazardous chemicals if exposed to extreme mechanical damage. If these chemicals contact the
skin or eyes, flush immediately with water for a minimum of 15 minutes and get prompt medical
attention. If any part of the battery is swallowed, contact a physician immediately. When
disposing of TPMS sensors, follow the correct procedures for hazardous material disposal.
Failure to follow these instructions may result in serious personal injury.

DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 08/11/2011
Diagnostic Methods
Effective Diagnostic Techniques
The following diagnostic process is critical for consistently successful diagnoses. Random methods work
inconsistently and often lead to multiple repairs and the accompanying frustration.
Understand and verify the symptom .
Understanding a symptom requires understanding normal operation.
Duplicate the concern. Re-create the same conditions that demonstrated the original
concern (road testing may be necessary).
Determine the responsible system .
Gather data, such as a visual inspection and an OASIS report.
Perform system tests, such as pressure tests or DTC retrieval.
Identify the responsible component .
Test the suspect component and related parts.
Determine the root cause
Examine related components (wiring faults, misalignments, incorrect adjustments) that
may be the actual cause or may have caused the component failure.
Repair all related faults to avoid repeat failures.
Verify the repair has corrected the concern (and not created any new ones) using the
identical conditions that demonstrated the original concern.
Diagnostic Scan Tool Testing
Network Test
Performing a network test is always recommended for analysis of electronic system concerns. Always
solve network issues before addressing individual symptoms or DTCs.
Recommended Practice: REFER to Symptom Chart in Section 418-00 to diagnose a network outage
or no response from an individual module (or modules).
DTC Retrieval
Generally, a good diagnostic strategy is to resolve all on-demand codes related to the system concern.
Retrieving all continuous DTCs can also be beneficial to understand historic issues or issues outside of
the suspect system that may be affecting your concern. On-demand testing should be done to ensure
the fault represented by a continuous DTC is still present.
Continuous Memory Diagnostic Trouble Codes (CMDTCs)
Modules that produce diagnostic trouble codes have a program that evaluates system conditions,
normally while the vehicle or system is in use. Module inputs can be checked for values indicating an
electrical fault with the monitoring circuit or component. Module outputs can be monitored for correct
function. Codes are stored when predefined limits are exceeded and retained even if the ignition is
turned off (generally DTC-retention is for 40+ ignition cycles). Not all continuous codes have a matching
on-demand code - and vice versa; this varies with different modules. For example, some network
communication codes are continuous only. It is important to note that the presence of a continuous DTC
does not guarantee that the fault currently exists.
Ford On-Demand DTCs
Ford Motor Company modules have a unique feature that performs a special diagnostic program at the
request of the technician (using a scan tool). This "On-demand" diagnostic program can exercise system
outputs not normally running when the car is parked and record observed faults. These diagnostic codes
are communicated to the scan tool; they are not recorded in module memory. An on-demand test is an
effective tool for evaluating real input and output conditions during module activity – activity that might
not normally be occurring during service bay conditions. For example, an air suspension module ondemand test can run the compressor, vent the system, and observe the report from the height sensor
even when the car is already at correct trim height and not requiring height adjustment.
Network Communication DTCs
Network DTCs (U-prefix codes) are often a result of intermittent concerns such as damaged wiring or
low battery voltage occurrences. Additionally, vehicle repair procedures (such as module reprogramming
or diagnostics with modules disconnected) often set network DTCs. Replacing a module to resolve a
network DTC is unlikely to resolve the concern. To prevent recurrence of intermittent network concerns,
inspect all network wiring, especially in-line and module connectors; test the vehicle battery.
Recommended practice: Clear the DTC and retest. If the DTC repeats, test the vehicle communication
network.
DTC Nomenclature (SAE J2012 and ISO 14229)
Many modules use 5-character DTCs followed by a 2-character failure-type code. The failure-type
(sometimes called "fault byte") digits provide information about specific fault conditions such as opens or
shorts to ground. Continuous memory DTCs have an additional 2-character DTC status code suffix to
assist in determining DTC history.
Integrated Diagnostic System (IDS) Scan Tool Usage
If The IDS Scan Tool Does Not Communicate With The VCM
1. Check the VCM power; examine the connection to the vehicle.
The VCM LED illumination prove-out confirms power and ground from the DLC are
provided to the VCM .
Recommended Practice: REFER to Section 418-00 , No Power to the Scan Tool, to
diagnose no power to the VCM .
2. Check the scan tool connection to the VCM .
3. Follow scan tool instructions to retry.
If The IDS Scan Tool Does Not Communicate With The Vehicle
The IDS scan tool first attempts to communicate with the PCM. After establishing communication with
the PCM, the scan tool then attempts to communicate with all other modules on the vehicle.
1. Verify the scan tool operation with a known good vehicle.
2. Verify the ignition is ON.
3. If an IDS session cannot be established with the vehicle ( IDS may state "No communication can
be established with the PCM"):
Choose "NO" when the scan tool prompts to retry communication.
Enter either a PCM part number, tear tag, or calibration number to identify the vehicle and
start a session.
The PCM part number can be determined from OASIS -- choose “HVBoM” from the
OASIS page and search for the PCM part number
The PCM part number and 4-character tear tag are printed on the PCM label.
Establish a session based on the PCM information (above).
4. Using the tool box menu, run the network test.
Determine if all modules on the network are unresponsive or if only the PCM does not
communicate.
Recommended practice: REFER to Symptom Chart in Section 418-00 to diagnose the
network outage or no response from the PCM.
Measuring Automotive Circuits
Wiring Pin (Terminal) Fit And The Use Of Rotunda Flex Probes
To avoid wiring pin (terminal) damage, Rotunda Flex Probes NUD105-R025D must be used to
connect test equipment or jumper wires to pins (terminals).
Male to female pin (terminal) fit is critical for connection reliability.
Pin (terminal) fit may be checked by using the mating pin (terminal) to test for normal
separation force (a damaged pin or terminal will have very low separation force from the
mating pin or terminal)
Correctly checking the separation force of small pins (terminals) may require removal of
the connector terminal guide/retainer if it adds drag to the pin (terminal) insertion or
removal
Replace damaged connectors or pins (terminals).
Use the Wiring Diagram connector view (cell 150) to identify the correct replacement
connector with pigtail.
Use the Wire Harness Terminal Repair Guide to identify and order the correct replacement
pin and pigtail. Available through Ford Dealers, REFER to FMC dealer website, or REFER
to www.fcs.dealersonnection.com/wire .
Checking Power-Providing Circuits
Measuring a power wire with the intended load disconnected using a DMM will only find open
circuits (open fuse or wire).
Recommended practice: Circuits carrying approximately 200-1000 mA* may be loaded with the
specified test light SGT27000. Measure circuit voltage with a DMM while the test light is
connected and illuminated. A reduction in the voltage present during test-light-loading indicates
excessive circuit resistance.
Recommended practice: Circuits carrying more than one ampere* should be loaded with a
device requiring similar current (e.g., a headlamp bulb may be effective). A reduction in the
voltage present during loading indicates excessive resistance.
*Circuit current is matched to wire gauge/size; Examples:
Conductor sizes of 24 gauge (.5 mm) or smaller are generally used to carry approximately
1 ampere (1000 mA) or less. Use of the test light to load these circuits is appropriate.
Conductor sizes of 20 gauge (.8 mm) or larger are generally used to carry approximately 5
amperes (5000 mA) or more. Match the substitute load (measure substitute load current
first as necessary) to this current level.
Checking Ground-Providing Circuits
The best method of checking ground circuits is to measure the circuit voltage drop during
component operation (or attempted operation).
An ohmmeter may be accurately used if the battery has been disconnected.
Recommended practice: Expect less than 2 ohms for most small diameter (18 gauge and
smaller) wires.
Ohmmeter low-resistance resolution (approximately 0.1 ohm) limits its use to circuits carrying less
than approximately 5 amperes (this is due to the fact that very small resistances, undetectable by
a DMM , cause significant voltage loss in higher current circuits).
DMM ohmmeter readings are easily corrupted by the normal voltage present (battery connected)
in many ground circuits.
Recommended practice: Reverse the leads and check for changes in the measurement.
Reversing the DMM lead connections should never change the resistance measurement
(unless the circuit contains a semi-conductor). Measurement (non-semi-conductor)
differences when leads are interchanged at the test points indicate invalid test results. The
presence of voltage corrupts the reading, and causes the meter reading to change when
the leads are reversed.
Checking Circuit Continuity
Recommended practice: Expect less than 2 ohms of resistance for most wires.
Ohmmeter low-resistance resolution (approximately 0.1 ohm) limits its use to circuits carrying less
than approximately 5 amperes. This is due to the fact that very small resistances, below the
resolution of a DMM , cause significant voltage loss in higher current circuits.
The DMM applies a small amount of voltage to the circuit or component to calculate resistance.
As a result, DMM ohmmeters are very sensitive to any level of voltage present. Voltage present in
the circuit will corrupt the DMM reading.
Checking For Unintended Continuity (Shorts) To Other Circuits
A DMM ohmmeter may be used to detect undesired circuit connections to:
Ground
Other unpowered circuits
Recommended practice: Expect greater than 10,000 ohms of resistance between two separate
circuits; the best result is an open circuit DMM indication (no detected resistance).
Shorts to voltage are checked with a DMM voltmeter
Recommended practice: Turn ignition on (with battery connected) and measure the circuit for
any voltage present (none should be present)
Checking Circuits By Back-Probing A Connector
Back-probing should be a testing method of last resort. It should only be employed where a
diagnostic step requires a circuit to be tested under actual operating conditions. Back-probing is a
risky testing method due to the uncertainty of the probe connection and the possibility of
damaging terminals.
Do not force test leads or other probes into connectors. Adequate care must be exercised to
avoid connector terminal damage while ensuring that good electrical contact is made with the
circuit or terminal. Failure to follow these instructions may cause damage to wiring, terminals, or
connectors and subsequent electrical faults.
Use Rotunda Back-Probe Pins POMA6411 to assist in making a good test connection and
to prevent connector or terminal damage during back-probing.
Do not test for the presence of voltage at a single point where zero volts is a possible result (you
cannot tell the difference between a bad probe contact and a zero volt result).
Do not test for continuity/opens (using a DMM ohmmeter) between two points (you cannot tell the
difference between bad probe contacts and an open circuit).
Back-probing may be used where the circuit must be analyzed with the voltage-drop method (if
the circuit carries greater than 5 amperes and no other means of testing will definitively eliminate
circuit resistance as a possible fault). A zero-volt result indicates incorrect test conditions (no
current flow) or bad back-probe connections.
Occasionally, module failure mode behavior will change the operation of a circuit when it is
opened for testing. Back-probing is an acceptable remedy for these testing dilemmas.
Circuit Analysis Using Jumper Wires (Creating Substitute Circuits)
Jumper wires may be employed for circuit analysis.
Cautions:
Always use fused jumper wires — the recommended universal-testing jumper wire fuse is
2-5 amperes; larger fuse ratings should be used only in special circumstances.
Use flex probes or equivalent to prevent connector terminal damage (flex probes are not
intended to carry higher currents necessary to operate motors such as a cooling fan or
blower motor).
Follow workshop manual testing directions when using jumper wires to avoid component or
harness damage due to incorrect jumper connections.
Never repair a circuit by adding a new wire in parallel to the old one (overlaying the circuit)
without fully understanding what caused the circuit to fail. Always find, examine, and repair
the fault to correct the root cause and to repair any adjacent wiring that has been
damaged.
Checking Modules
Generally, module failure rate is very low and therefore replacement modules usually do not
resolve the root cause. Incorrect replacement of a module is often the result of inadequate
testing.
Understand the correct module function.
Make sure programmable parameters are set correctly for the function in question (see the
list in Section 418-01 ).
Resolve DTCs first — as directed by Diagnostic Routines.
Test all inputs, both hard-wired and networked.
Test outputs (see "Checking module switching circuits" below).
Check applicable TSBs for module software changes (flash programming).
Checking module switching circuits.
Using the scan tool module-output command function (e.g., IDS Output State Control) to
activate components is a fast way to confirm an output is capable of being switched on by
the module. Testing that reveals normal module-output function confirms the need to
analyze the module inputs.
Don't apply ground or power directly to module-switched components with jumper wires
(unless directed by a workshop manual procedure), as the component can be damaged by
a direct connection to ground/power.

Unique Calibration
The Emission/Corporate Average Fuel Economy/CO2 Compliance Department is responsible for assigning
these calibration numbers. Unique identifications are assigned to cover similar vehicles to differentiate between
tires, drive configurations, final drive ratios and other calibration-significant factors.
These 2 characters are chosen by the analyst to provide identifiable information unique to each calibration. For
example, using the number 2 to denote a 2-valve engine versus using the number 4 to denote a 4-valve engine
provides an easily identifiable difference.

SECTION 100-04: Noise, Vibration and Harshness
DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Noise, Vibration and Harshness (NVH)
Noise is any undesirable sound, usually unpleasant in nature. Vibration is any motion, shaking or
trembling, that can be felt or seen when an object moves back and forth or up and down. Harshness is a
ride quality issue where the vehicle's response to the road transmits sharply to the customer. Harshness
normally describes a firmer than usual response from the suspension system. NVH is a term used to
describe these conditions, which result in varying degrees of dissatisfaction. Although a certain level of
NVH caused by road and environmental conditions is normal, this section is designed to aid in the
diagnosis, testing and repair of NVH symptoms.
Acceptable NVH
All internal combustion engines and drivelines produce some noise and vibration; operating in a real
world environment adds noise that is not subject to control. Vibration isolators, mufflers and dampers
reduce these to acceptable levels. A driver who is unfamiliar with a vehicle can think that some sounds
are abnormal when actually the sounds are normal for the vehicle type. As a technician, it is very
important to be familiar with vehicle features and know how they relate to NVH symptoms and their
diagnosis. For example, if the vehicle has automatic overdrive, it is important to test drive the vehicle
both in and out of overdrive mode.
Glossary of Terms

Diagnostic Theory
The shortest route to an accurate diagnosis results from:
system knowledge, including comparison with a known good system.
system history, including repair history and usage patterns.
condition history, especially any relationship to repairs or sudden change.
knowledge of possible sources.
using a systematic diagnostic method that divides the system into related areas.
The diagnosis and correction of NVH symptoms requires:
a road or system test to determine the exact nature of the symptom.
an analysis of the possible causes.
testing to verify the cause.
repairing any symptoms found.
a road test or system test to make sure the cause has been corrected or brought back to within an
acceptable range.
Diagnostic Procedure Overview
Qualifying the symptom by the particular sensation present can help narrow down the cause. Always use the
"symptom" to "system" to "component" to "cause" diagnosis technique. This diagnostic method divides the
problem into related areas to correct the customer concern.
Verify the "symptom".
Determine which "system(s)" can cause the "symptom" using the diagnostic tools described in this
section.
After determining the possible "system(s)", refer to the appropriate section in this manual to identify the
worn or damaged "components".
After identifying the "components", identify the "cause" of the failure.
Tools and Techniques
The diagnostic tools allow for a systematic collection of information that is necessary to accurately diagnose
and repair NVH problems. Remember that the vibrating source component (originator) may only generate a
small vibration. This small vibration can in turn cause a larger vibration/noise to emanate from another receiving
component (reactor), due to contact with other components (transfer path). For the best results, carry out the
test as follows:
a. Test drive the vehicle with the vibration sensor inside the vehicle.
b. Place the sensor in the vehicle according to feel.
If the condition is felt through the steering wheel, the source is most likely in the front of the
vehicle.
A vibration that is felt in the seat or floor only will most likely be found in the driveline, drive axle or
rear wheels and tires.
c. Record the readings. Also note when the condition begins, when it reaches maximum intensity and if it
tends to diminish above/below a certain speed.
If a vibration symptom is vehicle speed related, the tire and wheel rpm/frequency and driveshaft
frequency should be calculated.
If a vibration symptom is engine speed related, the engine, engine accessory and engine firing
frequencies should be calculated.
Frequencies with an amplitude reading of 0.06 Gs or less are barely perceptible NVH levels. No
corrective action is necessary.
d. Place the vibration sensor on or near the suspect area outside the vehicle.
e. Continue the road test, driving the vehicle at the speed the symptom occurs and take another reading.
f. Compare the readings.
A match in frequency indicates the problem component or area.
An unmatched test could indicate the symptom is caused by the engine, torque converter or
engine accessory. Use the diagnostic tools in the rpm mode and check if symptom is rpm related.
The following diagnostic tools and techniques can be used separately or in conjunction with each other to aid in
the diagnosis of NVH symptoms. They are listed in order of preference for ease in their use for locating these
symptoms.
NVH Analyzer (Vetronix)
The Mastertech® Series MTS 4000 Driveline Balance and NVH Analyzer (Vetronix) and the MTS 4100 NVH
analyzers are tools to aid in the identification and isolation of a noise, vibration or harshness symptom in a
vehicle. They measure noise and vibration data and compare it with data obtained from the vehicle's PCM as
well as vehicle variants that were entered by the user such as pulley size, axle ratio and tire size in order to
provide possible sources. The Mastertech® Series MTS 4000 Driveline Balance and NVH Analyzer (Vetronix)
and the MTS 4100 have the following characteristics:
Interface with the vehicle's computer system
Support and store vibration data input from 1 or 2 accelerometers
Support and store noise data input from 2 microphones
Provide a photo-tachometer for operation of the driveshaft balancing function
Provide a strobe output capable of driving a standard timing light
Contain a real-time clock circuit that provides time and date information which is used for tagging test
data
Have the capability to print to an external printer and interface with a PC
Can be powered from a variety of power sources: cigarette lighter, AC power or the internal battery pack
The Mastertech® Series MTS 4000 Driveline Balance and NVH Analyzer (Vetronix) and the MTS 4100 NVH
analyzers have 4 main operating modes. The first is for vibration diagnosis. This mode measures data from 1 or
2 accelerometers simultaneously while obtaining data from the vehicle. Then it carries out a frequency analysis
on the accelerometer information and compares the vibration frequencies with the frequencies associated with
various rotating components within the vehicle. The data can be presented in 4 different display modes:
principle component, bar chart, frequency spectrum or waterfall. All display mode formats contain the same
common elements, such as amplitude.
The second is for noise diagnosis. This mode measures noise from 1 or 2 microphones simultaneously. All
noise measurements are in decibels (dBs). All frequency bands used for noise measurements are the same as
for the vibration measurements, up to 1,000 Hz.
The third is driveshaft balancing. Driveshaft balancing is done using 1 or 2 accelerometers and a phototachometer. The accelerometers measure the vibration at both ends of the driveshaft, while the phototachometer measures the rotation speed and position reference. Refer to Section 205-00 .
The fourth is the strobe. A strobe or standard timing light can be connected to an analyzer, to provide a means
for measuring rotation speed. The strobe function is used for isolating the source of a vibration.
Electronic Vibration Analyzer (EVA)
The Electronic Vibration Analyzer (EVA) is a hand-held electronic scan tool which will assist in locating the
source of unacceptable vibrations. The vibration sensor can be remotely mounted anywhere in the vehicle for
testing purposes. The unit displays the 3 most common vibration frequencies and their corresponding
amplitudes simultaneously. A bar graph provides a visual reference of the relative signal strength (amplitude) of
each vibration being displayed and its relative G-force. The keypad is arranged to make the EVA simple to
program and use. Some of the functions include the ability to average readings as well as record, play back and
freeze readings. The EVA has a strobe balancing function that can be used to detect imbalance on rotating
components such as a driveshaft or engine accessories.

Frequencies have a range of plus or minus 2 Hz. A reading of 10 Hz can be displayed as an 8 Hz
through 12 Hz.
Vibrate Software®
Vibrate Software® (Rotunda tool number 215-00003) is a diagnostic aid which will assist in pinpointing the
source of unacceptable vibrations. The engine's crankshaft is the point of reference for vibration diagnosis.
Every rotating component will have an angular velocity that is faster, slower or the same as the engine's
crankshaft. Vibrate Software® calculates the angular velocity of each component and graphically represents
these velocities on a computer screen and on a printed vibration worksheet. The following steps outline how
Vibrate Software® helps diagnose a vibration symptom:
Enter the vehicle information. Vibrate will do all the calculations and display a graph showing tire,
driveshaft and engine vibrations.
Print a Vibration Worksheet graph. The printed graph is to be used during the road test.
Road test the vehicle at the speed where the vibration is most noticeable. Record the vibration frequency
rpm and the engine rpm on the worksheet graph. The point on the graph where the vibration frequency
rpm reading and the engine rpm reading intersect indicates the specific component group causing the
symptom.
A frequency measurement tool capable of measuring vibration frequency and engine rpm will be
needed.
Provides graphics of diagnostic procedures to aid in testing components.
Reed Tachometer
The Reed tachometer is a hand-held vibration sensor which will assist in locating the source of unacceptable
vibrations. The vibration sensor can be placed anywhere in the vehicle for testing purposes. The Reed
tachometer contains several reeds that are tuned to vibrate or resonate at different frequencies ranging from 10
to 80 Hz or 600 to 4,800 rpm. Though the Reed tachometer is able to measure multiple frequencies, it does not
measure amplitude.
Sirometer
The Sirometer measures frequency in hertz and rpm. To use the Sirometer, place it on any vibrating component
and slowly scroll the wire out by turning the knob. As the length of wire changes, so does its natural frequency.
Find the length of wire that vibrates with the highest amplitude. This frequency will match that of the vibrating
component. Read the frequency for that length of wire.
Combination EngineEAR/ChassisEAR
An electronic listening device used to quickly identify noise and the location under the chassis while the vehicle
is being road tested. The ChassisEARs can identify the noise and location of damaged/worn wheel bearings,
CV joints, brakes, springs, axle bearings or driveshaft carrier bearings.
EngineEAR Basic Unit
An electronic listening device used to detect even the faintest noises. The EngineEARs can detect the noise of
damaged/worn bearings in generators, coolant pumps, A/C compressors and power steering pumps. They are
also used to identify noisy lifters, exhaust manifold leaks, chipped gear teeth and for detecting wind noise. The
EngineEAR has a sensing tip, amplifier and headphones. The directional sensing tip is used to listen to the
various components. Point the sensing tip at the suspect component and adjust the volume with the amplifier.
Placing the tip in direct contact with a component will reveal structure-borne noise and vibrations, generated by
or passing through, the component. Various volume levels can reveal different sounds.
Mechanic's Stethoscope
A mechanic's stethoscope is an inexpensive tool for locating noises in engines and other moving parts. It can
be used to help diagnose piston slap, worn gears, faulty valves, coolant pump failure, damaged gaskets,
defective bearings and body squeaks.
Squeak and Rattle Repair Kit
The Squeak and Rattle Repair Kit (Rotunda tool number 164-R4900) contains lubricants and self-adhesive
materials that can be used to eliminate interior and exterior squeaks and rattles. The kit consists of the following
materials:
PVC (soft foam) tape
Urethane (hard foam) tape
Flocked (black fuzzy) tape
UHMW (frosted) tape
Squeak and rattle oil tube
Squeak and rattle grease tube
Ultrasonic Leak Detector
The Ultrasonic Leak Detector is used to detect wind noises caused by leaks and gaps in areas where there is
weatherstripping or other sealing material. It is also used to identify A/C leaks, vacuum leaks and evaporative
emission noises. The Ultrasonic Leak Detector includes a multi-directional transmitter (operating in the
ultrasonic range) and a hand-held detector. The transmitter is placed inside the vehicle. On the outside of the
vehicle, the hand-held detector is used to sweep the area of the suspected leak. As the source of the leak is
approached, a beeping sound is produced which increases in both speed and frequency.
Write-Up Job Aid
To assist the service advisor and the technician, a Write-Up Job Aid used during the interview process is
included with this material. The Write-Up Job Aid serves as a place to record all important symptom
information.
1: Customer Interview
The diagnostic process starts with the customer interview. The service advisor must obtain as much information
as possible about the symptom and take a test drive with the customer. There are many ways a customer will
describe NVH symptoms and this will help minimize confusion arising from descriptive language differences. It
is important that the symptom is correctly interpreted and the customer descriptions are recorded. During the
interview, complete the write-up job aid and ask the following questions:
When was it first noticed?
Did it appear suddenly or gradually?
Did any abnormal occurrence coincide with or precede its appearance?
Use the information gained from the customer to accurately begin the diagnostic process.
2: Pre-Drive Check
It is important to do a pre-drive check before road testing the vehicle. A pre-drive check verifies that the vehicle
is relatively safe to drive and eliminates any obvious faults on the vehicle.
The pre-drive check consists of a brief visual inspection. During this brief inspection, take note of anything that
will compromise safety during the road test and make those repairs/adjustments before taking the vehicle on
the road.
3: Preparing for the Road Test
Observe the following when preparing for the road test:
Review the information recorded on the write-up job aid. It is important to know the specific symptom the
customer has with the vehicle.
Do not be misled by the reported location of the noise/vibration. The cause can actually be some
distance away.
Conduct the road test on a quiet street where it is safe to duplicate the vibration/noise. The ideal testing
route is an open, low-traffic area where it is possible to operate the vehicle at the speed in which the
condition occurs.
While observing that they are not related to the symptom, eliminate the following:
If possible, lower the radio antenna in order to minimize turbulence.
Identify anything that could potentially make noise or be a source of wind noise.
Inspect the vehicle for add-on items that create vibration/noise.
Turn off the radio and the heating and cooling system blower.
The engine speed is an important factor in arriving at a final conclusion. Therefore, connect a diagnostic
tool, Vetronix, or an accurate tachometer to the engine, even if the vehicle has a tachometer. This will
make sure of an exact engine speed reading.
4: Verify the Customer Concern
Verify the customer concern by carrying out a road test, an engine run-up test or both.
The decision to carry out a road test, an engine run-up test or both depends on the type of NVH symptom. A
road test may be necessary if the symptom relates to the suspension system or is sensitive to torque. A Drive
Engine Run-Up (DERU) or a Neutral Engine Run-Up (NERU) test identifies noises and vibrations relating to
engine and drivetrain rpm. Remember, a condition will not always be identifiable by carrying out these tests,
however, they will eliminate many possibilities if carried out correctly.
5: Road Test
NOTE: It may be necessary to have the customer ride along or drive the vehicle to point out the symptom.
During the road test, take into consideration the customer's driving habits and the driving conditions. The
customer's concern just may be an acceptable operating condition for that vehicle.
The following is a brief overview of each test in the order in which it appears. A review of this information helps
to quickly identify the most appropriate process necessary to make a successful diagnosis. After reviewing this
information, select and carry out the appropriate test(s), proceeding to the next step of this process.
The Slow Acceleration Test is normally the first test to carry out when identifying an NVH symptom,
especially when a road test with the customer is not possible.
The Heavy Acceleration Test helps to determine if the symptom is torque-related.
The Neutral Coast Down Speed Test helps to determine if the symptom is vehicle speed-related.
The Downshift Speed Test helps to determine if the symptom is engine speed-related.
The Steering Input Test helps to determine how the wheel bearings and other suspension components
contribute to a vehicle speed-related symptom.
The Brake Test helps to identify vibrations or noise that are brake related.
The Road Test Over Bumps helps isolate a noise that occurs when driving over a rough or bumpy
surface.
The Engine Run-Up Tests consist of the Neutral Engine Run-Up (NERU) Test and the Drive Engine
Run-Up (DERU) Load Test. These tests help to determine if the symptom is engine speed-related.
The Neutral Engine Run-Up (NERU) Test is used as a follow-up test to the Downshift Speed Test when
the symptom occurs at idle.
The Drive Engine Run-Up (DERU) Load Test helps to identify vibration/noise sensitive to engine load or
torque. It also helps to reproduce engine speed-related symptoms that cannot be duplicated when
carrying out the Neutral Engine Run-Up (NERU) Test or the Neutral Coast Down Test.
The Engine Accessory Test helps to locate faulty belts and accessories that cause engine speed-related
symptoms.
The Vehicle Cold Soak Procedure helps to identify symptoms occurring during initial start-up and when
an extended time lapse occurs between vehicle usage.
Slow Acceleration Test
To carry out this test, proceed as follows:
Slowly accelerate to the speed where the reported symptom occurs. Note the vehicle speed, the engine
rpm and, if possible, determine the vibration frequency.
Attempt to identify from what part of the vehicle the symptom is coming.
Attempt to identify the source of the symptom.
If the source of the symptom has been identified as a result of this test, proceed to the appropriate
section for further diagnosis and repair. If the source has not been identified, continue with the road test.
Heavy Acceleration Test
To carry out this test, proceed as follows:
Accelerate hard from 0-64 km/h (0-40 mph).
Decelerate in a lower gear.
The symptom is torque-related if duplicated while carrying out this test.
If the source of the symptom has been identified as a result of this test, proceed to the appropriate
section for further diagnosis and repair. If the source has not been identified, continue with the road test.
Neutral Coast Down Speed Test
To carry out this test, proceed as follows:
Drive at a higher rate of speed than where the symptom occurred when carrying out the Slow
Acceleration Test.
Place the transmission in NEUTRAL and coast down past the speed where the symptom occurs.
The symptom is vehicle speed-related if duplicated while carrying out this test. This eliminates the
engine and the torque converter as sources.
If the symptom was not duplicated while carrying out this test, carry out the Downshift Speed Test to
verify if the symptom is engine speed related.
If the source of the symptom has been identified as a result of this test, proceed to the appropriate
section for further diagnosis and repair. If the source has not been identified, continue with the road test.
Downshift Speed Test
To carry out this test, proceed as follows:
Shift into a lower gear than the gear used when carrying out the Slow Acceleration Test.
Drive at the engine rpm where the symptom occurs.
The symptom is engine speed related if duplicated while carrying out this test. This eliminates the tires,
wheels, brakes and the suspension components as sources.
If necessary, repeat this test using other gears and NEUTRAL to verify the results.
If the source of the symptom has been identified as a result of this test, proceed to the appropriate
section for further diagnosis and repair. If the source has not been identified, continue with the road test.
Steering Input Test
To carry out this test, proceed as follows:
Drive at the speed where the symptom occurs, while making sweeping turns in both directions.
If the symptom goes away or gets worse, the wheel bearings, hubs, U-joints (contained in the axles of
Four-Wheel Drive (4WD) applications), and tire tread wear are all possible sources.
If the source of the symptom has been identified as a result of this test, proceed to the appropriate
section for further diagnosis and repair. If the source has not been identified, continue with the road test.
Brake Test
To carry out this test, proceed as follows:
With the brake released, accelerate the vehicle. While coasting (brake pedal released) to a stop in
NEUTRAL, note any abnormal rate of deceleration. Abnormal deceleration could indicate a parking
brake or service brake that is not fully releasing.
Warm the brakes by slowing the vehicle a few times from 80-32 km/h (50-20 mph) using light braking
applications.
Accelerate to 89-97 km/h (55-60 mph). Moderately apply the brakes and slow the vehicle to a stop.
A brake vibration can be felt in the steering wheel, seat or brake pedal. A brake noise can be heard upon
brake application and should diminish when the brake is released. For vehicles with separate park brake
shoes, noise or vibration from the parking brake system will not be affected by applying the hydraulic
brakes. On these systems, the parking brake system requires inspection if a parking brake concern is
suspected.
If the source of the symptom has been identified as a result of this test, proceed to the appropriate brake
section(s) for further diagnosis and repair. If the source has not been identified, continue with the road
test.
Road Test Over Bumps
To carry out this test, proceed as follows:
Drive the vehicle over a bump or rough surface one wheel at a time to determine if the noise is coming
from the front or the back and the left or the right side of the vehicle.
If the source of the symptom has been identified as a result of this test, proceed to the appropriate
section for further diagnosis and repair. If the source has not been identified, continue with the road test.
Neutral Engine Run-Up (NERU) Test
To carry out this test, proceed as follows:
Install a tachometer.
Place the vehicle in PARK on Front Wheel Drive (FWD) vehicles with automatic transmissions, or in
NEUTRAL for all other vehicles.
Slowly increase the engine rpm from idle to fuel cutoff or redline. When the symptom occurs, note the
engine rpm and, if possible, determine the vibration frequency.
Attempt to identify what part of the vehicle the symptom is coming from.
Attempt to identify the source of the symptom.
If the source of the symptom has been identified as a result of this test, proceed to the appropriate
section for further diagnosis and repair. If the source has not been identified, continue with the road test.
Drive Engine Run-Up (DERU) Load Test
To carry out this test, proceed as follows:
WARNING: Block all wheels, set the parking brake and firmly apply the service brake to reduce the
risk of vehicle movement during this procedure. Failure to follow these instructions may result in
serious personal injury.
NOTICE: Do not carry out the Engine Load Test for more than 5 seconds or damage to the transmission
or transaxle may result.
Block the front and rear wheels.
Apply the parking brake and the service brake.
Install a tachometer.
Shift the transmission into DRIVE, and slowly increase and decrease the engine rpm between an idle to
approximately 2,000 rpm. When the symptom occurs, note the engine rpm and, if possible, determine
the vibration frequency.
Repeat the test in REVERSE.
If the vibration/noise is duplicated when carrying out this test, inspect the engine and transmission or
transaxle mounts.
If the symptom is definitely engine speed-related, carry out the Engine Accessory Test to narrow down
the source.
If the source of the symptom has been identified as a result of this test, proceed to the appropriate
section for further diagnosis and repair. If the source has not been identified, continue with the road test.
Engine Accessory Test
To carry out this test, proceed as follows:
WARNING: Block all wheels, set the parking brake and firmly apply the service brake to reduce the
risk of vehicle movement during this procedure. Failure to follow these instructions may result in
serious personal injury.
NOTICE: Limit engine running time to one minute or less with belts removed or serious engine damage
will result.
NOTE: Use a frequency measurement tool to pinpoint accessory vibrations. A listening device, such as an
EngineEAR, will also help to identify noises from specific accessories.
Remove the accessory drive belt(s).
Slowly increase the engine rpm to where the symptom occurs.
If the vibration/noise is duplicated when carrying out this test, the belt(s) and accessories are not
sources.
If the vibration/noise was not duplicated when carrying out this test, install the accessory belt(s), one at a
time, to locate the source.
If the source of the symptom has been identified as a result of this test, proceed to the appropriate
section for further diagnosis and repair. If the source has not been identified, continue with the road test.
Vehicle Cold Soak Procedure
To carry out this procedure, proceed as follows:
Test preparations include matching customer conditions (if known). If not known, document the test
conditions: gear selection and engine rpm. Monitor the vibration/noise duration with a watch for up to 3
minutes.
Park the vehicle where testing will occur. The vehicle must remain at or below the symptom temperature
(if known) for 6-8 hours.
Before starting the engine, conduct a visual inspection under the hood.
Turn the key on, but do not start the engine. Listen for the fuel pump, ABS and air suspension system
noises.
Start the engine.
Isolate the vibration/noise by carefully listening. Move around the vehicle while listening to find the
general location of the vibration/noise. Then, search for a more precise location by using a stethoscope
or EngineEAR.
If the source of the symptom has been identified as a result of this test, proceed to the appropriate
section for further diagnosis and repair. If the source has not been identified, continue with the road test.
Classify NVH Symptom
For NVH concerns, it is necessary to classify the customer's concern into one of the 3 categories: noise,
vibration or harshness. The reason for this is that a customer concern may consist of a combination of
symptoms involving noise and vibration, or vibration and harshness. In cases where there are combination
symptoms, determine which diagnostic path to follow: noise, vibration or harshness. For example, if a customer
has a concern involving a noise and a vibration, and it is determined that it is vehicle speed-related, follow the
vibration diagnostic path.
Noise Symptoms
Once a symptom is classified as a noise, the particular conditions under which the noise occurs need to be
identified. These conditions are identified and verified during the road test. For example, a noise may only occur
while turning. The next step is to determine which systems on the vehicle are related to that condition. In this
case, the steering system and wheel/tire system may be suspect. After identifying possible systems, a
preliminary inspection of these systems should be done. If the source of noise is still unidentified, use a
listening device (such as the ChassisEAR) to pinpoint the source. Once the source has been identified,
determine if this source is related to the suspected system previously identified. If it is related, then complete
the repair to resolve the customer concern. If it is unrelated, then it is possible that the source of the noise is a
reactor to a noise being transmitted through a transfer path. If this is the case, repairing the reactor will not
resolve the customer concern. The transfer path must be identified and a determination made if the noise is
normal, but accentuated by the transfer path (conductor), or if the originator is the fault causing excessive noise
to transfer to another component through a conductor. There is a relationship between systems identified as
related to conditions and the noise transfer path. In some cases, the condition under which the noise occurs
has nothing to do with the identified source. This relationship is important in the diagnosis of noise concerns. It
is the first clue that the identified source of noise might be a reactor and that further investigation is needed to
diagnose a possible noise transfer path concern. Based on the results from the road test, make a determination
of which action in the symptom chart to take first.
Vibration Symptoms
Most vibrations consist of movements back and forth or up and down that repeat. Every time the vibrating
component goes through its complete range of motion and returns to the starting point is called a cycle. The
rate at which these cycles occur within a given time is called the frequency. Frequency is measured in cycles
per second or Hertz (Hz). One cycle per second equals one Hz. Once the frequency of a vibration is known,
calculations can be done to determine the system that is the source of the concern.
Order of Vibration
The order of a vibration refers to how often the vibration is present in one revolution of the component. For
example, a vibration that is present once each revolution of a component would be a first order vibration. A
vibration present twice each revolution of the component would be a second order vibration. Vibration orders do
not have to be whole numbers, they can have decimal values such as 1.5 order vibration or 3.08 order
vibration.
The concept of order of vibration is important to remember when the measured frequency of a vibration does
not seem to match the frequency calculations of any of the likely systems or components. As the order
increases, the frequency of the vibration will also increase by a multiple of that number.
For example, vibration may be present where the frequency is measured at 14 Hz. After doing the necessary
calculations it is determined the first order tire and wheel frequency is 7 Hz and the first order driveshaft
frequency is 22 Hz. Based on this information it can be determined the vibration is most likely a second order
tire and wheel vibration: 7 Hz (first order tire and wheel frequency) multiplied by 2 (second order) equals 14 Hz
(second order tire and wheel frequency).
Relationship of Vibration Frequency to Order of Vibration
After carrying out the road test as described in this section, the vibration was determined to be either vehiclespeed related or engine-speed related. That determination will identify the vibration frequency calculations that
should be done.
Vibration Type
Calculate
Vehicle-speed related
Tire-speed vibration frequency
Driveshaft-speed vibration frequency
Engine-speed related
Engine vibration frequency
Engine accessory vibration frequency
Engine firing vibration frequency
In calculating and using frequency readings, it is important to remember the direct relationship between Hz and
rpm. One Hz is equal to 60 rpm. This is easy to remember; think of Hz as cycles per second. There are 60
seconds in a minute, therefore multiply Hz reading by 60 to get rpm. Conversely, divide rpm by 60 to get Hz.
Use the Frequency and RPM Calculations Worksheet to calculate system/component frequencies. The
worksheet provides the necessary steps to determine each system/component group frequency.
Frequency Calculations
Calculating Tire and Wheel Frequency
For a vibration concern, use the vehicle speed to determine tire/wheel frequency and rpm. Calculate tire and
wheel rpm and frequency by carrying out the following:
Measure the diameter of the tire.
Record the speed at which the vibration occurs.
Obtain the corresponding tire and wheel rpm and frequency from the Tire Speed and Frequency Chart.
If the vehicle speed is not listed, calculate the tire and wheel frequency as follows:
Divide the vehicle speed at which the vibration occurs by 16 km/h (10 mph). Multiply that number
by the 16 km/h (10 mph) tire rpm listed for that tire diameter in the chart. Then divide that number
by 60.
For example, if calculating the frequency based on vehicle speed in km/h for a 64 km/h vibration
with 835 mm tires, divide 64 km/h by 16 km/h = 4. Multiply 4 by 105 rpm = 420. Divide 420 by 60
seconds = 7 Hz at 64 km/h.
If calculating the frequency based on vehicle speed in mph for a 40 mph vibration with 33 inch
tires, divide 40 mph by 10 mph = 4. Multiply 4 by 105 rpm = 420. Divide 420 by 60 seconds = 7 Hz
at 40 mph.
The calculated frequency of 7 Hz is the first order tire and wheel vibration; the second order tire
and wheel vibration would be twice this number at 14 Hz; the third order tire and wheel vibration
would be 21 Hz; and so on.

Calculating Driveshaft Frequency
Knowing the tire and wheel frequency allows for easy calculation of driveshaft frequency. The driveshaft drives
the tires through the rear axle. Therefore, to determine driveshaft frequency, multiply tire and wheel frequency
by the ratio of the rear axle. Calculate driveshaft frequency by performing the following steps:
Obtain the axle ratio of the vehicle. Suppose the vehicle has a vibration problem at 64 km/h (40 mph)
and a rear axle ratio of 2.93:1.
Multiply the tire and wheel frequency of 7 Hz (calculated previously) with the rear axle ratio of 2.93:1.
This results in a driveshaft frequency of 21 Hz at a vehicle speed of 64 km/h (40 mph).
The calculated frequency of 21 Hz is the first order driveshaft frequency; the second order frequency of the
driveshaft is twice this number, or 42 Hz; and so on.
Calculating Engine Frequency
Use the engine rpm where the vibration symptom occurs to determine engine frequency. Calculate engine
frequency by dividing the engine rpm by 60 (the number of seconds in a minute). For example, if the
corresponding engine rpm of a vibration concern on a vehicle is 2,400 rpm, the resulting engine frequency is 40
Hz. Therefore, a 40 Hz vibration is a first order engine vibration. For purposes of vibration diagnosis, the engine
also includes the torque converter and exhaust system.
Calculating Engine Accessory Frequency
Belt-driven engine accessories often produce vibrations at different frequencies than the engine itself. This is
because the drive ratio created by the different size pulleys causes them to rotate at different speeds.
Determining engine accessory frequency is comparable to calculating driveshaft frequency.
Calculate engine accessory frequency by performing the following steps:
Determine the size ratio factor between the accessory pulley and the crankshaft pulley. For example, if
the diameter of the crankshaft pulley is 6 inches and the accessory pulley diameter is 2 inches, the
accessory pulley rotates 3 times for every crankshaft rotation (6 divided by 2).
Multiply the engine rpm where the vibration condition occurs by the number of times the accessory pulley
is rotating per crankshaft revolution. For example, if the engine rpm is 2,400 rpm, the accessory is
rotating at 7,200 rpm (2,400 rpm multiplied by 3).
Divide the accessory rpm by 60 (the number of seconds in a minute). In this example, the engine
accessory frequency is 120 Hz (7,200 divided by 60).
Calculating Engine Firing Frequency
Engine firing frequency is a term used to describe the pulses an engine creates from the firing of the cylinders.
Engine firing frequency depends on how many cylinders an engine has. The number of times an engine fires a
cylinder with each crankshaft revolution is equal to one-half the number of cylinders. A 4-cylinder engine fires 2
cylinders with each crankshaft revolution. Two revolutions of the crankshaft fire all 4 cylinders. A 6-cylinder
engine fires 3 cylinders with each crankshaft revolution. An 8-cylinder engine fires 4 cylinders for each
crankshaft revolution.
Calculate engine firing frequency by performing the following steps:
Multiply the engine rpm where the vibration symptom occurs by the number of cylinders fired with each
crankshaft revolution. For example, a vehicle with a 6-cylinder engine experiences a vibration concern at
2,400 rpm. The engine is firing the cylinders at 7,200 times per minute (3 multiplied by 2,400).
Divide this number by 60 (the number of seconds in a minute) to obtain the engine firing frequency. In
this example, the engine firing frequency is 120 Hz (7,200 divided by 60) at 2,400 rpm.
Frequency and RPM Calculations Worksheet
Harshness Symptoms
Harshness is customer perception which gives the impression of no isolation from the tire/wheel and
suspension system. Harshness may be caused by road conditions, temperature changes, component damage
and/or incorrect customer modifications on original components/specifications. Customers usually experience
harshness when the vehicle is driving over bumps or potholes and in cold weather conditions. Harshness can
also be experienced with excessive tire pressure, sporty tires, heavy-duty springs and shocks, or other vehicle
modifications. Some aftermarket tires, even with the correct size, may change vehicle behavior and produce
customer concerns. The first step in diagnosing a harshness concern is to determine if the concern was
experienced only in certain specific operating conditions, such as large potholes or extremely cold weather. In
these cases, harshness should be considered normal. A known good vehicle can be driven under the same
conditions and the rides can be compared to determine whether the concern is normal or vehicle specific. The
second step is to check tire pressure and make sure it was set within vehicle specifications. The third step is to
inspect for aftermarket or modified components and determine if they are the cause of the harshness complaint.
If the harshness concern persists after the above steps, it is possible that some components are damaged.
Based on the results from the road test, make a determination of which action in the symptom chart to take first.
NVH Symptom Chart Categories
A good diagnostic process is a logical sequence of steps that lead to the identification of a causal system. Use
the symptom and possible system categories as follows:
Identify the operating condition that the vehicle is exhibiting.
Match the operating condition to the symptom.
Verify the symptom.
Calculate the frequency and order of the symptom.
Identify which category or system(s) could cause the symptom.
Refer to the section indicated to identify and diagnose the symptom or confirm that the system is not the
source of the condition.
Use the diagnostic instructions in this section along with the necessary listed tools to identify the vibration order
and to isolate the symptom and the possible systems associated with that symptom. Then based on the results
from the road test, make a determination of which action in the symptom chart to take first. Since it is possible
any one of multiple systems may be the cause of the symptom, it may be necessary to use a process of
elimination type diagnostic approach to pinpoint the concern. Refer to the section(s) indicated to identify and
isolate the cause or rule that system out as being the causal system for the symptom.
Vehicle-Speed Related Vibrations
NOTE: Any assembly that is out of balance will only cause a first order vibration, it will not cause a higher order
vibration.
When a vehicle-speed related vibration is present, both tire-speed related vibration and driveshaft-speed
related vibration calculations should be carried out.

Inspection and Verification
Dust and Water Leaks
Most dust and water leaks occur due to missing or incorrectly installed body sealer or components. The
source of the leak is detected by:
pressurizing the vehicle and testing with soapy water.
Locate and tape off the body vents.
Turn the blower motor to HIGH.
Turn the air recirculation to OFF.
Close the windows and doors.
Open the hood and spray soapy water along body seams and grommets. Make sure to test
the areas around the A-pillar at the fender and hood hinge area.
Check for bubbles.
inspecting for a dust pattern or water path near and above the area in question.
removing any trim or carpet in the general area of the leak.
road testing or water hose testing the vehicle.
placing a bright light under the vehicle, removing any necessary trim or carpet and inspecting the
interior of the body at joints and weld lines.
Wind Noise
Most wind noise leaks occur at the corners of the windows or in the doors. Wind noise is detected by
driving the vehicle at highway speeds or at speeds as specified by the customer. Drive the vehicle in 4
different directions, with all of the windows closed, the radio off and the A/C blower motor off.
Squeak and Rattle
Squeak and rattle noises are generally caused by loose parts, contact or relative movement between 2
surfaces or loose wires and connectors. Detect the source of the noise by stopping movement of the
suspect part by hand or using dampening or low friction materials.

Rear View Mirrors — Exterior
Special Tool(s)
Fluke 77-IV Digital Multimeter
FLU77-4 or equivalent
Flex Probe Kit
NUD105-R025D or equivalent
Principles of Operation
LH and RH exterior rear view mirror glass movement is controlled by the exterior rear view mirror switch
and the LH and RH exterior rear view mirror motors. Adjusting the exterior rear view mirror switch to the
LH or RH position determines which exterior rear view mirror motor to control.
Heated Exterior Mirror
The rear window defrost switch controls the operation of the heated exterior rear view mirrors. The
heated exterior rear view mirrors only operate when the rear window defrost system is operating. The
heated exterior rear view mirror voltage is supplied by the rear defrost relay output from the Body
Control Module (BCM) and Central Junction Box (CJB) fuse 25 (7.5A), which isolates the heated exterior
rear view mirrors from the rear window defrost system in the event of a fault.
Inspection and Verification
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical and electrical damage.

Rear View Mirrors — Interior
Special Tool(s)
Fluke 77-IV Digital Multimeter
FLU77-4 or equivalent
Principles of Operation
Interior Auto-Dimming Rear View Mirror
The interior auto-dimming rear view mirror automatically reduces the glare caused by headlamps
reflecting in the interior rear view mirror. Voltage is supplied to the interior auto-dimming mirror when the
ignition is in the RUN or ACC position. The auto-dimming feature is disabled when the vehicle is in
REVERSE.
The interior auto-dimming rear view mirror has 2 photoelectric sensors, a forward facing sensor and a
rearward facing sensor, that detect forward and rearward light conditions. Based on these inputs, the
automatic dimming feature adjusts the reflectance level of the interior rear view mirror glass to eliminate
unwanted glare. The reflectance level of the mirror glass is variable and depends on the amount of rear
glare in relation to ambient light conditions in front of the interior mirror.
When the forward sensor detects daytime conditions, the rearward sensor is inactive and the mirror
stays in a high reflectance mode. When the forward sensor detects nighttime conditions, the rearward
sensor is active and detects glare from the headlights of vehicles approaching from the rear or other
glare-producing light sources. To provide increased visibility when backing up, the interior rear view
mirror automatically returns to a high reflectance mode whenever the vehicle is in REVERSE.
If the forward or rearward sensors are blocked, the interior auto-dimming rear view mirror might not work
correctly.
Inspection and Verification
1. Verify the customer concern.

Pinpoint Test E: The Auto-Dimming Mirror Does Not Operate Correctly
Refer to Wiring Diagrams Cell 124 , Power Mirrors for schematic and connector information.
Normal Operation
The interior auto-dimming mirror contains 2 photoelectric sensors: one in the front of the interior rear
view mirror and one mounted on the glass side of the mirror. If the sensors are blocked, the autodimming feature may not operate correctly. Always verify both sensors are not physically blocked before
attempting to diagnose auto-dimming mirror concerns. Whenever the gear selector lever is placed in
REVERSE, the interior auto-dimming mirror temporarily disables the auto-dimming feature. The autodimming feature is enabled again when the gear selector lever is moved out of REVERSE.

NOTE: If a new heater mat is needed on a front passenger seat cushion equipped with an Occupant
Classification System (OCS) system, install a new OCS service kit with a heater mat already adhered to
the cushion foam pad.
The cushion heater mats are serviceable separately. A heater mat can be peeled away from a foam pad
and a new one adhered in its place providing excessive foam is not removed from the foam pad. If
excessive foam is removed during removal, a new foam pad must be installed. A heater mat cannot be
reused; the 2-way tape adhesive will no longer hold the heater mat position on the foam pad causing it
to shift or bunch up.
Occupant Classification System (OCS) System
NOTE: OCS system components [seat wiring harness, seat cushion foam pad, bladder with pressure
sensor and Occupant Classification System Module (OCSM)] are calibrated to each other and are
serviced as an assembly. If new OCS system components are needed, an OCS system service kit must
be installed as an assembly.

Principles of Operation — Heated Seats
Heated Seats
The heated seat system only operates when the engine is running. When the heated seat switch(es)
(located on the instrument panel) is activated, it supplies a ground signal to the Body Control Module
(BCM). When the BCM receives the heated seat switch signal, it activates the appropriate (driver or
passenger) heated seat relay, (located in the Central Junction Box (CJB). When the heated seat relay is
activated, voltage is supplied to the cushion heater mat. The cushion heater mats are directly connected
to ground to complete the electrical circuit to heat the seat.
Each cushion heater mat contains a non-serviceable internal thermostatic switch that closes when cold
to complete the heater grid circuit and heat the seat. When hot, the thermostatic switch opens the heater
grid circuit and allows the seat to cool. During normal operation, several minutes may be required before
seat temperature is increased and several more minutes of cooling before the heater mats continue with
heating. The heated seat indicator illuminates continuously while the thermostatic switch cycles between
open and closed.
The seat should be occupied to correctly test for normal operation. Temperature measuring devices do
not provide an accurate method for testing heated seat operation as surface temperatures are subject to
human and environmental characteristics. Correct testing requires heater mat resistance measurements
which have tight tolerances affecting heat cycle time length.
The heated seat system does not time-out. A heated seat remains on until it is turned off by the heated
seat switch or the ignition is switched OFF.
Inspection and Verification
1. Verify the customer concern by operating the heated seat functions.
2. Visually inspect for obvious signs of mechanical and electrical damage.

Pinpoint Test C: The Heated Seat is Inoperative/Does Not Operate Correctly — Passenger
Refer to Wiring Diagrams Cell 119 , Climate Controlled Seats for schematic and connector information.
Normal Operation
The heated seat system only operates when the engine is running. When the passenger heated seat
switch (located on the instrument panel) is activated, it supplies a ground signal to the Body Control
Module (BCM). When the BCM receives the heated seat switch signal, it activates the passenger heated
seat relay (located in the Central Junction Box (CJB)) by grounding the relay control circuit. When the
heated seat relay is activated, voltage is supplied to the passenger cushion heater mat. The passenger
cushion heater mat is directly connected to ground to complete the electrical circuit to heat the seat.
DTC B1036:12 (Right Front Seat Heater Element: Circuit Short To Battery) — if the passenger
heated seat relay drive circuit CHS07 (GY/BU) is shorted to voltage and the BCM attempts to
activate the passenger heated seat relay, this DTC sets and the seat fails to heat.
DTC B1036:14 (Right Front Seat Heater Element: Circuit Short To Ground or Open) — if the
passenger heated seat relay drive circuit CHS07 (GY/BU) is open or shorted to ground and the
BCM attempts to activate the passenger heated seat relay, this DTC sets and the seat fails to
heat (circuit open) or may be on at all times (circuit shorted to ground) until the ignition is turned
OFF.
DTC B115A:23 (Front Passenger Seat Heater: Signal Stuck Low) — sets when the BCM detects
the passenger heated seat switch is active during on-demand self-test or has been active for
more than 2 minutes.

Pinpoint Test D: The Heated Seat Does Not Operate Correctly — Driver or Passenger Seat Heats
When the System is Off
Refer to Wiring Diagrams Cell 119 , Climate Controlled Seats for schematic and connector information.
Normal Operation
The heated seat system only operates when the engine is running. When the driver or passenger heated
seat switch (located on the instrument panel) is activated, it supplies a ground signal to the Body Control
Module (BCM). When the BCM receives the heated seat switch signal, it activates the appropriate
(driver or passenger) heated seat relay (located in the Central Junction Box (CJB)). When the heated
seat relay is activated, voltage is supplied to the cushion heater mat. The cushion heater mats are
directly connected to ground to complete the electrical circuit to heat the seat.
DTC B1034:14 (Left Front Seat Heater Element: Circuit Short To Ground or Open) — if the driver
heated seat relay drive circuit CHS02 (YE/BU) is open or shorted to ground and the BCM
attempts to activate the driver heated seat relay, this DTC sets and the seat fails to heat (circuit
open) or may be on at all times (circuit shorted to ground) until the ignition is turned OFF.
DTC B1036:14 (Right Front Seat Heater Element: Circuit Short To Ground or Open) — if the
passenger heated seat relay drive circuit CHS07 (GY/BU) is open or shorted to ground and the
BCM attempts to activate the passenger heated seat relay, this DTC sets and the seat fails to

Make sure the voltage to the Occupant Classification System Module (OCSM) is
greater than 8 volts and less than 18 volts.
Make sure the OCS system is not at a temperature below 6°C (42°F) or above 36°C
(97°F) when initiating the OCS system reset process. If the vehicle has been
exposed to extreme cold or hot temperatures, the vehicle must be exposed and kept
at a temperature between 6°C to 36°C (42°F to 97°F) for a minimum of 30 minutes.
Make sure nothing is present on the passenger seat before and during the OCS
system reset process.
Prior to carrying out the OCS system reset, make sure a minimum of 8 seconds has
elapsed after cycling the ignition switch ON.
Carry out the OCS system reset.
11. If the first system reset attempt was unsuccessful, carry out a thorough visual inspection of the
following and repair any concerns found.

bag warning indicator will illuminate continuously for approximately 6 seconds and then turn off. If
an air bag SRS fault is present, the air bag warning indicator will:
- fail to light.
- remain lit continuously.
- flash at a 5 Hz rate ( RCM not configured).
The air bag warning indicator may not illuminate until approximately 30 seconds after the ignition
switch has been turned from the OFF to the ON position. This is the time required for the RCM to
complete the testing of the SRS . If the air bag warning indicator is inoperative and a SRS fault
exists, a chime sounds in a pattern of 5 sets of 5 beeps. If this occurs, diagnose and repair the air
bag warning indicator and any SRS fault discovered.

WARNING: Occupant classification system(OCS) parts are calibrated as an assembly
and must only be replaced in the configuration they are sold. Never separate parts of an
assembly. Failure to follow this instruction may result in incorrect operation of the OCS
and increases the risk of serious personal injury or death in a crash.
NOTICE: To prevent system failure, take the following precautions before carrying out the
Occupant Classification System (OCS) system reset:
Make sure the voltage to the Occupant Classification System Module (OCSM) is
greater than 8 volts and less than 18 volts.
Make sure the OCS system is not at a temperature below 6°C (42°F) or above 36°C
(97°F) when initiating the OCS system reset process. If the vehicle has been
exposed to extreme cold or hot temperatures, the vehicle must be exposed and kept
at a temperature between 6°C to 36°C (42°F to 97°F) for a minimum of 30 minutes.
Make sure nothing is present on the passenger seat before and during the OCS
system reset process.
Prior to carrying out the OCS system reset, make sure a minimum of 8 seconds has
elapsed after cycling the ignition switch ON.
Carry out the OCS system reset.
28. If the first system reset attempt was unsuccessful, carry out a thorough visual inspection of the
following and repair any concerns found.
OCS system connector and wiring for damage.
Pressure sensor hose for kinks and/or damage.
Seat-related wiring harness and body wiring harness terminals and connectors for
damage.
29. NOTE: Cycle the ignition switch after the OCS system reset.
Carry out a second OCS system reset. If the second attempt is unsuccessful, install a new OCS
system service kit. For additional information, refer to Occupant Classification System in Section
501-20B .
30. Prove out the SRS as follows:
Turn the ignition switch from ON to OFF. Wait 10 seconds, then turn the ignition switch back to
ON and visually monitor the air bag warning indicator with the air bag modules installed. The air
bag warning indicator will illuminate continuously for approximately 6 seconds and then turn off. If
an air bag SRS fault is present, the air bag warning indicator will:
- fail to light.
- remain lit continuously.
- flash at a 5 Hz rate ( RCM not configured).
The air bag warning indicator may not illuminate until approximately 30 seconds after the ignition
switch has been turned from the OFF to the ON position. This is the time required for the RCM to
complete the testing of the SRS . If the air bag warning indicator is inoperative and a SRS fault
exists, a chime sounds in a pattern of 5 sets of 5 beeps. If this occurs, diagnose and repair the air
bag warning indicator and any SRS fault discovered.
Use a scan tool and clear all continuous DTCs from the RCM and Occupant Classification
System Module (OCSM).

SECTION 501-11: Glass, Frames and Mechanisms
DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 02/09/2011
Glass, Frames and Mechanisms
The glass, frames and mechanisms consist of the following:
Body Control Module (BCM)
Door glass top run
Door window glass
Door window regulator
Door window regulator motor
Rear quarter glass
Rear window defrost switch (integral to the HVAC module)
Rear window glass
Window control switches
Windshield glass
The power window system only operates if the ignition is in the RUN position.
The master window control switch:
disables operation of the rear passenger windows when the lock-out switch is in the UNLOCK
position.
automatically raises/lowers the driver window when activated momentarily to the second detent
position.
The power window system can be operated from either the master window control switch or from the
window control switches located on each door panel.
Rear Window Defrost
The engine must be running for the rear window defrost system to operate. The rear window defrost
system is controlled by the BCM . When the rear window defrost switch (integral to the HVAC module) is
pressed, the BCM supplies voltage to the rear window defrost grid. An LED indicator illuminates when
the rear window defrost is activated. The rear defrost self actuates when the ambient air temperature is
less than 5° C (41° F) and engine coolant temperature is less than 60° C (140° F). The rear window
defroster LED indicator does not illuminate when the rear defroster self actuates.

Principles of Operation
LH Front Window Operation
NOTE: The master window control switch and the LH front window motor each contains integral
electronics which must be initialized whenever:
a new window control switch is installed.
a new window regulator and motor is installed.
a new window glass is installed.
a glass top run removal and installation.
carrying out any operation in which grease or lubricants are applied to the window system.
battery voltage has been removed from the LH front window control switch for more than 3
minutes (for example, battery or window control switch disconnected).
For additional information, refer to Window Motor Initialization in this section.
The master window control switch contains electronics that control the one-touch up/down operation.
The master window control switch receives feedback from the Hall-effect sensors which are integral to
the LH front window motor. If the Hall-effect sensors or any associated circuitry fails, the window still
operates but the one-touch up/down and obstacle detection is inoperative.
If an obstacle has been detected in the window opening as the window glass is moving upward, the
window motor automatically reverses direction and moves the glass toward the bounce-back position.
To override a bounce-back condition (for example, to overcome the resistance of ice on the window or
seals), close the window glass twice until it reaches the resistance and allow it to reverse to the bounce-
back position. On the third attempt, activate and hold the master window control switch in the UP
position. The window travels up with no bounce-back protection.
Rear Window Defrost
The engine must be running for the rear window defrost system to operate. When the rear window
defrost switch (integral to the HVAC module) is pressed, a ground signal is sent to the Body Control
Module (BCM). When the BCM receives the defrost request signal, it supplies voltage to the rear window
defrost grid. The rear defrost self actuates when the ambient air temperature is less than 5° C (41° F)
and engine coolant temperature is less than 60° C (140° F). The rear window defroster LED indicator
does not illuminate when the rear defroster self actuates.
The BCM deactivates the rear window defrost grid when one of the following conditions is met:
The rear window defrost switch is pressed when the feature is active
The ignition state is changed from ON to OFF/LOCK
The 14-minute timing function is complete

Refer to Wiring Diagrams Cell 100 , Power Windows for schematic and connector information.
NOTE: The master window control switch and the LH front window motor each contain integral
electronics which must be initialized whenever:
a new window control switch is installed.
a new window regulator and motor is installed.

battery voltage has been removed from the LH front window control switch for more than 3
minutes (for example, battery or window control switch disconnected).
For additional information, refer to Window Motor Initialization in this section.
Normal Operation
The master window control switch contains the electronics which controls the one-touch up/down
operation of the LH front window. The master window control switch determines window position based
upon feedback from two Hall-effect sensors (integral to the LH front window motor). Voltage and ground
is supplied to the Hall-effect sensors from the master window control switch. If any fault occurs in the
Hall-effect sensor circuits, the LH front window still operates (only the one-touch operation and obstacle
detection is inoperative).
This pinpoint test is intended to diagnose the following:

Pinpoint Test J: The Defrost System is Inoperative
Refer to Wiring Diagrams Cell 56 , Heated Window for schematic and connector information.
Normal Operation
The engine must be running for the rear window defrost system to operate. When the rear window
defrost switch (integral to the HVAC module) is pressed, a ground signal is sent to the Body Control
Module (BCM). When the BCM receives the defrost request signal, it supplies voltage to the rear window
defrost grid. When the rear window defrost is active, the BCM supplies voltage through a dedicated
feedback circuit to the HVAC module to illuminate the LED indicator.

Component Test
Grid Wire Test
1. Using a bright lamp inside the vehicle, inspect the wire grid from the outside. A broken grid wire
appears as a brown spot.
2. Run the engine at idle. Set the rear window defrost switch to ON. The indicator light should
illuminate.
3. Working inside the vehicle with a voltmeter, contact the broad, red-brown stripes of the back glass
window grid (positive lead to B+ side and negative lead to ground side). The meter should read
10-13 volts. A lower voltage reading may indicate a loose grid connection.
4. Contact a good ground point with the negative lead of the meter. The voltage reading should not
change. If the voltage increases, this indicates a loose ground connection. A voltage reading of
less than 10 volts indicates a loose B+ side connection.
5. With the negative lead of the meter grounded, touch each grid line of the rear window defrost
glass at its midpoint with the positive lead. A reading of approximately 6 volts indicates the line is
good. A reading of 0 volt indicates the line is broken between the midpoint and the B+ side of the
grid line. A reading of 12 volts indicates the circuit is broken between the midpoint of the grid line
and ground.
6. Pinpointing the exact position of the break can be accomplished (if the voltmeter reads 0 volt
when the midpoint of the grid line is touched with the positive lead of the voltmeter) by moving the
positive lead of the voltmeter toward the B+ side of the grid line and touching the grid line until the
voltmeter reads 12 volts. If the voltmeter reads 12 volts when the midpoint of the grid line is
touched with the positive lead of the voltmeter, simply move the positive lead of the voltmeter
toward the ground connection of the grid line and touch the grid line until the voltmeter reads 0
volt.

NOTE: The grid line material is not embedded into the glass, but is baked to the glass surface and
consequently can be scraped off. An undamaged grid line will have small ridges that project above the
surface of the glass and can easily be felt when running a fingernail across them. Grid lines that have
been "razor bladed" will feel smooth when a fingernail is dragged across the affected area. Inoperative
lines may appear to the eye to be undamaged due to residue remaining on the glass and will require
diagnosis with a voltmeter or 12V test lamp. For additional information, refer to Diagnosis and Testing in
this section.
1. Bring the vehicle up to a room temperature of at least 16°C (60°F) or above.
2. NOTICE: Do not use scrapers, sharp instruments or abrasive window cleaners on the
interior surface of the rear window glass as this may cause damage to the grid lines.
Clean the entire grid line repair area with glass cleaner and 0000 steel wool to remove all dirt,
wax, grease, oil or other foreign material.
3. Mark the location of the grid break on the exterior of the rear window glass.
4. Using a polypropylene film fine line tape, mask the area directly above and below the grid break
extending the tape 26 mm (1.02 in) beyond the concern area in both directions. The break area
should be at the center of the mask.
5. NOTE: If the brown layer is not broken or missing, apply only the silver grid repair compound to
the break. If both the brown and silver layers of the grid are broken or missing, apply a coating of
the lacquer touch up paint across the break in the grid line prior to applying the rear window
defroster repair compound. Do not overlap the silver grid line with the paint. Several applications
may be necessary to achieve a color match.
NOTE: Allow at least 5 minutes of drying time between applications for the touch up paint or the
silver repair coating. Applying fewer coats or not allowing adequate drying time between coats will
produce repaired resistance that is greater than OEM resistance, resulting in poor defrost
performance and excessive localized heating.
Apply the repair coating to the grid break area in several smooth, continuous strokes. Extend the
silver repair coating at least 6.35 mm (0.25 in) on both sides of the break area.
Apply a minimum of 6 applications of the grid repair compound.
6. NOTE: The repair coating air-dries in approximately one minute and can be energized after 5
minutes. Optimum adhesion occurs after approximately 24 hours.
Allow the repair area to dry completely and remove the mask.
7. NOTICE: Be careful not to damage the grid line with the razor blade. If this occurs,
additional repair may be necessary.
Remove any excess repair compound above or below the grid line with a razor blade.
8. NOTE: The interior side of the grid lines are not painted, but due to the silver tarnishing will tend
to change the grid to a gold or brown color. The repair area will be bright silver and will also
tarnish over time to match the rest of the grid.
Test the system for normal operation.

1. Bring the vehicle up to room temperature of at least 16°C (60°F) or above.
2. NOTE: The new terminal will cover the original terminal location, but it must be placed so that the
terminal conductive areas will be placed on a good conductive base.
Clean the bus bar in the area to be repaired with steel wool (000 to 0000 grade), and then with
glass cleaner to remove all dirt, wax, grease, oil or other foreign material.
3. NOTICE: Do not use any type of flame torch or flame-heated soldering gun for this
procedure. Use of these tools provide inadequate heat generation at the tip and the
exhaust heat can cause damage to plastic trim parts in the area. Use only an electric
soldering gun with 100 watts or more of power. Before using the soldering gun, be sure to
melt a small amount of rosin core solder to the tip. The solder will assist in achieving
better heat transfer from the soldering gun tip to the new terminal.
NOTE: Depending on the original terminal location, and whether the terminal is covered by pillar
trim, will determine where to locate the new terminal. Some grid line bus bars may only allow the
placement of the terminal above or below the original tab location due to space limitations. For
most vehicle applications, the replacement tab location will cover the original tab location, but still
allow the replacement tab to attach to the bus bar on good conductive material.
Place the replacement terminal type A over the original tab location, making sure the conductive
areas of the terminal will be on a good conductive area. Do not place the terminal tab foot on the
original location, which does not have conductive material.
4. Hold the terminal in place with an item such as a regular lead pencil at a 90 degree angle from
the terminal. (Holding at other than a 90 degree angle may allow the terminal to slip when the
solder liquefies.)
5. NOTE: The new terminal has pre-applied solder, flux and temperature-sensitive paint. The paint
provides a visual indication when the terminal has reached the correct temperature to melt solder
on the terminal. When the correct temperature is achieved, the temperature paint will liquefy and
change color.
Place the soldering gun tip on the top of the terminal, but not on the painted areas of the tab.
Energize the soldering gun and watch for the painted area of the terminal to liquefy and change
color. The paint should liquefy in approximately 25-45 seconds after heating. As soon as the paint
color completely changes on either side of the terminal, de-energize the soldering gun and
continue to hold the terminal in place with the soldering gun and pencil for an additional 30
seconds.
6. Remove the soldering gun and pencil from the terminal. The terminal should be allowed to cool
for another 2 minutes before the wiring lead is attached to the terminal.
7. Attach the electrical lead connection to this terminal, turn on the heated rear window and verify
the operation.

WARNING: Repair any corrosion found on the pinch weld. The pinch weld is a structural
component of the vehicle. Corrosion left unrepaired may reduce the structural integrity of the
vehicle. Failure to follow this instruction may result in serious injury to vehicle occupant(s).
NOTE: Avoid scratching the pinch weld. Repair all minor scratches or exposed metal on the pinch weld
following manufacturer's instructions. Use the same brand pinch weld primer, glass primer and urethane
adhesive.
Using an appropriate tool, trim the urethane adhesive leaving a 1 mm to 2 mm (0.04 in to 0.08 in) base
of original equipment urethane adhesive on the pinch weld.
2. Using a clean shop towel, brush or oil-free compressed air, clean the pinch weld area around the
existing urethane adhesive. Remove any foreign material or water that may have entered during glass
removal.
3. If installing the original rear quarter window glass, remove the excess urethane adhesive.
4. Clean the inside of the rear quarter window glass with glass cleaner.
5. NOTE: Be sure to use the same brand of cure-rate products for the urethane adhesive and glass primer.

procedure.
If installing a new rear quarter window glass, apply glass primer according to the manufacturer's
instructions. Allow at least 6 minutes to dry.
6. Cut the urethane adhesive applicator tip to specification.
7. NOTE: The rear quarter window glass must be positioned within 10 minutes of applying the urethane
adhesive.
NOTE: Use either a Air Caulking Gun or a high-ratio, electric or battery-operated caulk gun that will
apply the urethane adhesive with less effort and a continuous bead.
Apply urethane adhesive on top of the existing trimmed urethane adhesive bead on the pinch weld,
starting and ending at the bottom of the rear quarter window glass near the center, making sure there
are no gaps in the bead.
8.
WARNING: Do not drive vehicle until the urethane adhesive seal has cured. Follow urethane
adhesive manufacturer's curing directions. Inadequate or incorrect curing of the urethane
adhesive seal will adversely affect glass retention. Failure to follow these instructions may result
in serious injury to vehicle occupant(s).

Power Lock/Unlock
The power lock/unlock feature requests all of the vehicle doors locked or unlocked upon a customer
request from the door lock control switch (part of the Front Controls Interface Module (FCIM)) in the
vehicle. The power door locking system functions independently of ignition status or vehicle speed.
Door Lock Indicator
The door lock indicator provides visual indication of the door lock status. When the light on the door lock
control switch is illuminated it indicates that all of the doors are locked. When the light is off it indicates
that one or more doors are unlocked.
Central Locking/Unlocking
The central locking/unlocking feature allows all of the doors to be locked or unlocked from a key in the
driver door lock cylinder. To unlock the driver door with stepped unlock enabled, turn the key once to the
unlock position. To unlock all of the doors with stepped unlock enabled, turn the key a second time to
unlock all of the doors. To unlock all of the doors with stepped unlock disabled, turn the key once to the

The driver door is opened within 10 minutes of the ignition being switched to the OFF mode.
Refer to Autolock and Auto-Unlock Programming in this section for programming information.
Smart Unlock
Without Intelligent Access (IA)
The smart unlock feature prevents the doors from locking with the key in the ignition lock cylinder. When
the vehicle is locked from the central lock control switch and the key is in the ignition lock cylinder with
one of the front doors open, the doors lock and then unlock.
The vehicle can still be locked with the key in the ignition lock cylinder by locking the doors with another
key in the driver door lock cylinder.
With Intelligent Access (IA)
NOTE: The IA smart unlock feature iIs only available on late build vehicles.
The smart unlock feature prevents the doors from electronically locking when an IA key is left inside the
vehicle. When a door becomes ajar, the interior of the vehicle is scanned for an IA key. If an IA key is
inside the vehicle when a door is ajar and a lock command is received the doors lock and then unlock.
The vehicle can still be locked with an IA key inside the vehicle by locking the doors with another key in
the driver door lock cylinder or the lock button pressed on another key.
Luggage Compartment/Liftgate Smart Unlock Feature — Intelligent Access (IA)
The luggage compartment/liftgate smart unlock feature prevents the luggage compartment/liftgate from
latching when an IA key is detected inside the luggage compartment area. When the luggage
compartment lid/liftgate is closed when the doors are locked, the luggage compartment is searched for
an IA key. If an IA key is detected inside the luggage compartment, the luggage compartment lid/liftgate
releases.
An IA key can still be locked inside a luggage compartment/ liftgate area by closing the luggage
compartment lid/liftgate when the doors are unlocked and then locking the doors after the luggage
compartment lid/ liftgate is closed with the key inside. Or if a second IA key is in range of the luggage
compartment/ liftgate IA antenna when the luggage compartment lid/liftgate is closed.
Driver/Passenger Door Intelligent Access (IA) Feature
The driver/passenger door IA feature allows the doors to be locked or unlocked without having to use
the door lock cylinder or the Remote Keyless Entry (RKE) transmitter feature. With a programmed IA key
within 1 m (3 ft) outside the driver or passenger front door, press the lock button on the exterior door
handle. The doors lock or unlock depending upon their current state (locked/unlocked).
Driver Door Intelligent Access (IA)
The driver door IA feature either unlocks just the driver door or all four doors. If stepped unlock Is
enabled, the driver door Is the only door that unlocks from the driver door IA feature. If stepped unlock Is
disabled, then all four doors unlock. The driver door IA feature always locks all four doors. Refer to
Stepped Unlock Programming in this section for programming information.
Passenger Door Intelligent Access (IA)
The passenger door IA feature always locks or unlocks all four doors.
Luggage Compartment/Liftgate Intelligent Access (IA) Feature
The luggage compartment IA feature allows the luggage compartment lid to be released without having
to use the interior luggage compartment lid release switch or the keyless entry keypad. With a
programmed IA key within 1 m (3 ft) outside the luggage compartment lid/liftgate, press the release
button, and the luggage compartment lid/liftgate latch releases.
Remote Keyless Entry (RKE)
The RKE transmitter carries out the following functions:
Unlocks the driver door
Unlocks all doors

and the doors are closed
Sounds the horn twice when LOCK is pressed twice within 3 seconds, and any door is ajar
The RKE transmitter has a normal operating range of 20 m (66 ft).
Without Intelligent Access (IA)
This RKE system uses an Integrated Keyhead Transmitter (IKT). The IKT incorporates both the Passive
Anti-Theft System (PATS) functions and the RKE transmitter functions in a single device. The key
programming is a two step procedure, the PATS information is programmed into the IPC and then the
RKE transmitter Transmitter Identification Code (TIC) is programmed into the Body Control Module
(BCM). The vehicle accepts the programming of up to 8 keys. Refer to the key programming procedures
in Section 419-01B for the PATS programming, and then refer to Remote Keyless Entry (RKE)
Transmitter Programming in this section to program the RKE transmitter.
With Intelligent Access (IA)
This RKE system uses an IA key. The IA key incorporates both the PATS functions and the RKE
transmitter functions in a single device. The RKE transmitter is programmed automatically during IA key
programming. During IA key programming, the Remote Function Actuator (RFA) module obtains the TIC
from the IA key. The RFA module accepts programming of up to 8 IA keys. Refer to the key
programming procedures in Section 419-01B for the for key programming information.
Remote Keyless Entry (RKE) Lock/Unlock Control — Unlock
The RKE feature provides a stepped (if enabled) process for unlocking the doors. Upon receipt of the
first request for unlocking the doors, the RKE control feature requests the BCM to unlock the driver door
only and provides a long flash of the turn signals. If another unlock request is received within 3 seconds
of the first, the RKE feature requests the BCM to unlock all of the doors. This feature can be disabled so
that all of the doors unlock on the first press of the unlock button. Refer to Stepped Unlock Programming
in this section.
Remote Keyless Entry (RKE) Lock/Unlock Control — Lock
The RKE feature requests that all of the doors be locked when the lock button is pressed. On any press
of the lock button with all doors closed, the BCM flashes the turn signals once. If any door is ajar, no
flash occurs. As soon as the last door is closed, the BCM provides the flash of the turn signals. If 2
presses of the lock button are received within 3 seconds, the horn chirps once and the turn signals flash
twice (once for each button press) to indicate that all of the doors are closed and locked. If any door is
ajar when the second lock request is received within 3 seconds of the first, the RKE transmitter feature
requests the BCM chirp the horn twice without flashing the turn signals to indicate it locked all the doors
but one or more doors are ajar.
Remote Keyless Entry (RKE) Luggage Compartment Lid/Liftgate Release
The RKE feature provides luggage compartment lid/liftgate release function. The luggage compartment
lid release system is inhibited when the ignition is on and vehicle speed exceeds 7 km/h (5 mph).

Principles of Operation — Without Intelligent Access (IA)
Power Door Locks
The Body Control Module (BCM) monitors the door lock control switch and the driver door lock cylinder. When
the BCM receives an unlock/lock command from either the door lock control switch or the driver door lock
cylinder, the BCM energizes a relay (internal to the SJB ) to supply the correct power and grounds for the door
lock actuators. The power door locks function independently of ignition status or vehicle speed.
Door Lock Indicator
For a visual indication of the door lock status, the BCM controls the door lock indicator on the door lock control
switch. If all four doors are locked, the indicator is illuminated. If any one door is unlocked, the indicator turns
off. The BCM monitors the door lock status through the unlock switches inside each of the 4 door latches. The
BCM uses the input from the unlock switches to determine if the indicator should be illuminated or off.
Luggage Compartment Lid/Liftgate Release
The luggage compartment lid/liftgate release system is inhibited when the vehicle speed exceeds 8 km/h (5
mph) and when the vehicle doors are locked. The luggage compartment lid/liftgate latch releases the luggage
compartment lid/liftgate when the release switch on the luggage compartment lid/liftgate or on the Remote
Keyless Entry (RKE) transmitter is pressed. When the BCM receives a signal to release the luggage
compartment lid/liftgate, the BCM supplies voltage to the latch. The luggage compartment lid/liftgate latch then
actuates to release the luggage compartment lid/liftgate.
Remote Keyless Entry (RKE)
The BCM interprets radio frequency signals from the RKE transmitters. The BCM requests the illuminated entry
feature to turn the interior lamps on when an unlock command is received. If a lock command is received, the
illuminated entry feature turns off.
The RKE transmitter supplies a signal to the antenna internal to the BCM when any button is pressed. The
BCM then supplies voltage to the appropriate door lock actuator(s) to lock or unlock the doors or release the
luggage compartment lid/liftgate.
Principles of Operation — WithIntelligent Access (IA)
Intelligent Access (IA) Components
Exterior Front Door Handles
The exterior front door handles both contain an Intelligent Access (IA) antenna and a lock switch. The antennas
and lock switches are hardwired to the Remote Function Actuator (RFA) module. When a lock switch is
pressed, it signals the RFA module there is an IA request. When the RFA module receives the request it
activates the IA antenna in the corresponding door handle. The low frequency signal from the IA antenna
activates an IA key.
Luggage Compartment/Liftgate Intelligent Access (IA) Antenna
The luggage compartment/liftgate IA antenna is hardwired to the RFA module and, when activated by the RFA
module, it transmits a low frequency signal that activates an IA key.
Remote Functions Receiver (RFR) Module
The Remote Functions Receiver (RFR) module is hardwired to the RFA module and is a receiving antenna that
receives the high frequency signals from an IA key. It also receives the signals from an RKE command.
Intelligent Access (IA) Key
The IA key receives the low frequency signals from the IA antennas. When the IA key is activated by one of the
low frequency signals, it sends out a high frequency signal that is received by the RFR module. The IA key also
contains a key blade that is used to enter the vehicle as a backup.
Power Door Locks
The BCM monitors the door lock control switch and the driver door lock cylinder. When the BCM receives an
unlock/lock command from either the door lock control switch or the driver door lock cylinder, the BCM
energizes a relay (internal to the SJB ) to supply the correct power and grounds for the door lock actuators. The
power door locks function independently of ignition status or vehicle speed.
Door Lock Indicator
For a visual indication of the door lock status, the BCM controls the door lock indicator on the door lock control
switch. If all 4 doors are locked, the indicator is illuminated. If any one door is unlocked, then the indicator turns
off. The BCM monitors the door lock status through the unlock switches inside each of the four door latches.
The BCM uses the input from the unlock switches to determine if the indicator should be illuminated or off.
Luggage Compartment Lid/Liftgate Release
The luggage compartment lid/liftgate release system is inhibited when the vehicle speed exceeds 8 km/h (5
mph) and when the vehicle doors are locked. The luggage compartment lid/liftgate latch releases the luggage
compartment lid/liftgate when the release switch on the luggage compartment lid/liftgate or on the Remote
Keyless Entry (RKE) transmitter is pressed. When the BCM receives a signal to release the luggage
compartment lid/liftgate, the BCM supplies voltage to the latch. The luggage compartment lid/liftgate latch then
actuates to release the luggage compartment lid/liftgate.
Driver/Passenger Door Intelligent Access (IA) Feature
The driver/passenger door IA feature allows the doors to be locked or unlocked without having to use the door
lock cylinder or the RKE transmitter. With a programmed IA key within 1 m (3 ft) of either front door handle
outside of the door, press the lock button on the exterior door handle and, depending upon their current state,
the doors either lock or unlock. The IA feature from the driver door only unlocks the driver door and the IA
feature from the passenger door unlocks all four doors. The IA feature from either front door locks all four
doors.
When the RFA module detects that a lock button is pressed on a front exterior door handle, it activates the low
frequency antenna in the corresponding exterior front door handle. The low frequency antenna sends out a
signal to the IA key. The low frequency signal activates the IA key and the IA key then sends a high frequency
signal back to the RFR module. The RFR module interprets the high frequency signal from the IA key and
sends the information to the RFA module. If the RFA module determines that it is a programmed key, it sends a
message over the Medium Speed Controller Area Network (MS-CAN) to the BCM . Depending upon the signal
received from the RFA module, the BCM either unlocks the driver door, unlocks all 4 doors, or locks all 4 doors.
Luggage Compartment/Liftgate Intelligent Access (IA) Feature
The luggage compartment/liftgate IA feature allows the luggage compartment lid to be released without using
an RKE transmitter. With a programmed IA key within 1 m (3 ft) outside of the luggage compartment lid/liftgate,
press the release button on the luggage compartment lid/liftgate, and the luggage compartment lid/liftgate latch
releases.
The luggage compartment/liftgate release switch is connected to both the BCM and the RFA module. When the
doors are unlocked, the BCM receives the signal from the switch and releases the luggage compartment
lid/liftgate. When the doors are locked, the BCM ignores the input from the switch and only releases the
luggage compartment lid/liftgate if it receives a signal from the RFA module for the luggage
compartment/liftgate IA feature.
When the RFA module detects a signal from the luggage compartment lid/liftgate release switch, it activates the
low frequency antenna in the rear bumper cover. The low frequency antenna sends out a signal to the IA key.
The low frequency signal activates the IA key and the IA key then sends a high frequency signal back to the
RFR module. The RFR module interprets the high frequency signal from the IA key and sends the information
to the RFA module. If the RFA module determines that it is a programmed key, it sends a message over the
MS-CAN to the BCM to release the luggage compartment lid/liftgate.
Remote Keyless Entry (RKE)
The IA key transmitter supplies a signal to the RFR module when any button is pressed. The RFR module
interprets the information from the IA key and sends a signal to the RFA module. If the RFA module determines
that it is a programmed key, it sends a message over the MS-CAN to the BCM . Depending upon the signal
received from the RFA module, the BCM either unlocks the driver door, unlocks all 4 doors, locks all 4 doors, or
releases the luggage compartment lid/liftgate.
The BCM requests the illuminated entry feature to turn the interior lamps on when an unlock command is
received. If a lock command is received, the illuminated entry feature turns off.

Normal Operation
The Battery Junction Box (BJB) fuse 6 (30A) provides voltage for the power lock/unlock system and the
luggage compartment/liftgate release. The BCM has a dedicated ground for the power lock/unlock system. The
BCM contains internal relays that are energized depending on input received from the door lock control switch,
driver door lock cylinder and the Remote Keyless Entry (RKE) transmitters. Upon a lock request, the BCM
supplies voltage on the all door lock circuit and ground on the driver and passenger door unlock circuits. Upon
an unlock request, the voltage and ground are reversed on the previously listed circuits.

Pinpoint Test C: All Door Locks Are Inoperative From The Door Lock Control Switch
Refer to Wiring Diagrams Cell 117 , Remote Keyless Entry and Alarm for schematic and connector information.
Normal Operation
The Body Control Module (BCM) sends a voltage signal to the door lock control switch. When the door lock
control switch is pressed, the voltage signal is routed to ground, signaling the BCM to lock or unlock the doors.
The BCM monitors the door lock actuator positions and either locks or unlocks the doors depending upon their
current state. If the doors are locked and the switch is pressed, the BCM unlocks the doors. If the doors are
unlocked and the switch is pressed, the BCM locks the doors. The door lock control switch is part of the Front
Controls Interface Module (FCIM) and shares the same ground.
DTC B108F:23 (Cabin Lock/Unlock Switch: Signal Stuck Low) — a continuous and on-demand DTC that
sets when the BCM detects a short to ground from the door lock control switch input circuit. This DTC
may also set if the door lock control switch is pressed for longer than 2 minutes.

Pinpoint Test D: The Door Lock Control Switch Indicator Is Inoperative/Always On
Refer to Wiring Diagrams Cell 117 , Remote Keyless Entry and Alarm for schematic and connector information.
Normal Operation
The Body Control Module (BCM) controls the door lock control switch indicator. The door lock control switch is
illuminated when the doors are locked and off when the doors are unlocked. The BCM provides voltage to the
door lock control switch indicator and the indicator uses a common ground in the Front Controls Interface
Module (FCIM). When the ignition is in the RUN mode, the indicator is always on as long as the doors are
locked. When the ignition is in the OFF mode, the indicator illuminates for approximately 30 seconds when a
lock command is received and then it turns off.
The BCM monitors the lock/unlock monitor circuit to determine the status of the door locks and to turn the
indicator on or off. All 4 door latches have an internal switch that are connected to ground when the door is
unlocked and open when the door is locked.
DTC B1108:92 (Driver Door Central Locking Motor: Performance or Incorrect Operation) — an ondemand DTC that sets when the BCM detects the incorrect feedback on the door lock/unlock monitor
circuit. During the BCM self-test, the BCM energizes the internal lock and unlock relays to lock and
unlock all of the doors. When the BCM commands the doors to lock, it checks for an open on the
lock/unlock monitor circuit. When the BCM commands the doors to unlock, it checks for a short to
ground on the lock/unlock monitor circuit.

Pinpoint Test E: The Luggage Compartment Lid/Liftgate Latch Release Is Inoperative/Does Not Operate
Correctly
Refer to Wiring Diagrams Cell 113 , Luggage Compartment for schematic and connector information.
Normal Operation
When the Body Control Module (BCM) receives an open request from the luggage compartment lid/liftgate
switch or a Remote Keyless Entry (RKE) transmitter, the BCM supplies voltage to the luggage compartment
lid/liftgate latch which releases the latch. The luggage compartment lid/liftgate latch has a dedicated ground
circuit.
The BCM sends a voltage signal to the luggage compartment lid/liftgate release switch through the input circuit.
When the luggage compartment lid/liftgate release switch is pressed, the voltage signal is routed to ground,
signaling the BCM to release the luggage compartment lid/liftgate. The luggage compartment lid/liftgate release
switch has a dedicated ground circuit. The BCM disregards the input from the switch and does not release the
luggage compartment lid/liftgate if the doors are locked.
The luggage compartment lid/liftgate release switch is also hardwired to the Remote Function Actuator (RFA)
module on vehicles with Intelligent Access (IA). The RFA module uses the switch input for the luggage
compartment lid/liftgate IA feature.
DTC B113E:23 (External Boot/Trunk Release Switch: Signal Stuck Low) — a continuous and ondemand DTC that sets if the BCM detects a short to ground on the luggage compartment lid/liftgate
release switch input circuit. This DTC also sets if the switch is pressed for longer than 2 minutes.
DTC B113E:24 (External Boot/Trunk Release Switch: Signal stuck high) — a DTC that sets if the RFA
module detects a short to ground on the luggage compartment lid/liftgate release switch input circuit.
DTC B1187:92 (Trunk Motor: Performance or Incorrect Operation) — an on-demand DTC that sets if the
BCM detects a short to ground on the luggage compartment lid/liftgate ajar switch input circuit. During
the BCM self-test, the BCM energizes the internal luggage compartment lid/liftgate relay to release the
latch. When the BCM commands the luggage compartment lid/liftgate relay to release, it checks for an
open on the luggage compartment lid/liftgate ajar input circuit, indicating the luggage compartment
lid/liftgate opened.

Pinpoint Test G: The Remote Keyless Entry (RKE) Transmitter Is Inoperative — With Intelligent Access
(IA)
Refer to Wiring Diagrams Cell 117 , Remote Keyless Entry and Alarm for schematic and connector information.
Normal Operation
When an Remote Keyless Entry (RKE) button is pressed on a Intelligent Access (IA) key, the IA key sends a
radio signal to the Remote Functions Receiver (RFR) module based on the user selected RKE transmitter
button. The RFR module then communicates the RKE command to the Remote Function Actuator (RFA)
module over a dedicated single circuit network. Once the RFA module receives the RKE command, it sends the
command to the Body Control Module (BCM) over the Medium Speed Controller Area Network (MS-CAN). The
BCM receives the RKE command and either locks or unlocks the doors or releases the luggage compartment
lid/liftgate. The RKE transmitters and RFA module use a rolling code to prevent the code from being captured
by a code grabber. The system advances the counter in the RKE transmitter and RFA module every time an
RKE transmitter button is pressed.
The RFR module receives voltage from Central Junction Box (CJB) fuse 7 (7.5A) and has a dedicated ground
circuit. The RFR module sends all RKE and IA key information and requests to the RFA module through a
dedicated single circuit network.
DTC U201F:00 (External Receiver: No Sub Type Information) — sets when the RFA module has lost
communication with the RFR module.

Pinpoint Test J: The Intelligent Access (IA) Feature Is Inoperative From A Front Door
Refer to Wiring Diagrams Cell 117 , Remote Keyless Entry and Alarm for schematic and connector information.
Normal Operation
The Remote Function Actuator (RFA) module controls the unlocking and locking of the doors when requested
by the Intelligent Access (IA) feature. When the lock button is pressed on either front door exterior door handle,
the RFA module activates the external antenna (located in the front exterior door handles), which sends out a
low frequency signal. If an IA key is within 1 m (3 ft) of the front exterior door handle, the low frequency signal
activates the IA key. When the IA key is activated, it sends a high frequency signal back to the Remote
Functions Receiver (RFR) module. Once the RFR module receives the IA key information, it sends it to the
RFA module. If the RFA module determines that it was a programmed IA key, it sends the lock or unlock
request to the Body Control Module (BCM) over the Medium Speed Controller Area Network (MS-CAN). Once
the unlock request is received the BCM unlocks the driver door if stepped unlock is enabled, or all doors if
stepped unlock is disabled.

Pinpoint Test K: The Luggage Compartment/Liftgate Intelligent Access (IA) Is Inoperative
Refer to Wiring Diagrams Cell 113 , Luggage Compartment Lid Release for schematic and connector
information.
Refer to Wiring Diagrams Cell 117 , Remote Keyless Entry and Alarm for schematic and connector information.
Normal Operation
The Remote Function Actuator (RFA) module controls the release of the luggage compartment/liftgate when
requested by the Intelligent Access (IA) feature. When the luggage compartment/liftgate button is pressed on
the luggage compartment lid/liftgate, the RFA module activates the external antenna (located behind the rear
bumper cover), which sends out a low frequency signal. If an IA key is within 1 m (3 ft) of the antenna, the low
frequency signal activates the IA key. When the IA key is activated, it sends a high frequency signal back to the
Remote Functions Receiver (RFR) module. Once the RFR module receives the IA key information, it sends it to
the RFA module. If the RFA module determines that it was a programmed IA key, it sends the release request
to the Body Control Module (BCM) over the Medium Speed Controller Area Network (MS-CAN). Once the BCM
receives the request, it releases the luggage compartment lid/liftgate.

Pinpoint Test N: The Smart Unlock Is Inoperative
Normal Operation
For vehicles without Intelligent Access (IA), when the key is in the ignition lock cylinder and the door lock
control switch is pressed to lock the doors with any door ajar the Body Control Module (BCM) automatically
unlocks all the doors. This feature helps prevent the keys from being locked in the vehicle by unlocking the
doors if the key is in the ignition and either front door is ajar.
NOTE: For vehicles with IA , the smart unlock feature is only available on late build vehicles.
For vehicles with IA , the Remote Function Actuator (RFA) module sends a message over the Medium Speed
Controller Area Network (MS-CAN) to the BCM to command all doors to unlock to prevent an IA key from being
inadvertently locked inside the vehicle. When the vehicle is locked using the door lock control switch with the
door ajar and then closed, the RFA module searches the interior of the vehicle for an IA key. The RFA module
searches the interior of the vehicle by activating all 3 low frequency passive start antennas. If an IA key is inside
the vehicle the signal from the passive start antennas activate the IA key, and it sends a signal back to the RFA
module through the Remote Functions Receiver (RFR) module. If the RFA module detects there is an IA key
inside the vehicle, it sends a command to the BCM to unlock all of the doors.
The vehicle can still be locked with the key in the ignition (vehicles without IA ) or a key inside the vehicle
(vehicles with IA ), a key in the door lock cylinder, or the lock button on another Remote Keyless Entry (RKE)
transmitter.

Pinpoint Test O: The Luggage Compartment/Liftgate Smart Unlock Is Inoperative
Normal Operation
The luggage compartment/liftgate smart unlock feature prevents the luggage compartment/liftgate from latching
when an Intelligent Access (IA) key is detected inside the luggage compartment. When the Remote Function
Actuator (RFA) module detects the luggage compartment lid/liftgate is closed with the doors locked, it searches
the luggage compartment using the low frequency passive start antenna located behind the rear seat for an IA
key. If an IA key is inside the luggage compartment the signal from the passive start antenna activates the IA
key, and it sends a signal back to the RFA module through the Remote Functions Receiver (RFR) module. If an
IA key is detected, the luggage compartment lid/liftgate releases. To override the luggage compartment/liftgate

Transmitter (IKT). The RKE transmitter for an Intelligent Access (IA) key is programmed automatically
during key programming. Refer to the key programming procedures in Section 419-01B .
NOTE: There is an audible feedback chime heard indicating that the programming mode for the RKE
transmitter portion of the Integrated Keyhead Transmitter (IKT) has been initiated. The chime is also
heard for every key that is programmed and when programming of a RKE transmitter was successful.
The chime is not heard if the vehicle has not been transitioned from transport to NORMAL mode.
1. Close all doors.
2. Buckle the front safety belts.
3. Use the door lock control switch to electronically unlock all door locks.
4. Turn the ignition from the OFF to RUN position 4 times in rapid succession (within 6 seconds),
with the fourth turn ending in OFF.
5. NOTE: If no action is taken within 10 seconds after a transmitter has been programmed, the
programming sequence ends.
Within 10 seconds, press any button on the RKE transmitter to be programmed. After the first
RKE transmitter is programmed, press a button on each subsequent RKE transmitter to be
programmed (each within 10 seconds of each other).
6. NOTE: If programming mode is exited and no key is learned, all keys (if one or two were
programmed) are erased for RKE transmitter operation.
Exiting the programming mode is accomplished if one of the following occurs:
The key transitions to the RUN position.
10 seconds have passed since entering programming mode or since the last RKE
transmitter was programmed.
The maximum number (8) of RKE transmitters have been programmed.
7. Check the operation of the transmitter. If the door locks do not respond for the programmed RKE
transmitter(s), wait several seconds and press the button again. If the door locks still fail to
respond, refer to Handles, Locks, Latches and Entry Systems in this section.

Principles of Operation
Windshield Wiper System
The wiper and washer system functions are activated by the wiper/washer switch which provides an
input to the Body Control Module (BCM). The BCM then provides an output to operate the desired wiper
system feature. The windshield and rear window wiper systems share the window washer pump and
cannot be used simultaneously. The windshield wiper system only operates when the ignition is ON.
The windshield wiper system offers 4 wipe modes:
Single
Intermittent (6 settings)
Normal
Fast
The wiper system setting of the wiper/washer switch is transmitted to the BCM to actuate the wiper
motor and set the wiper speed. Normal wipe speed remains available in the event of BCM failure.
Windshield Intermittent Wipe
The windshield intermittent wipe setting of the wiper/washer switch is transmitted to the BCM to actuate
the wiper motor and set the wiper delay interval. The wiper/washer switch has 6 intermittent wiper delay
settings ranging from a short to a long delay:
Level 1 delay = 1.2 seconds
Level 2 delay = 4 seconds
Level 3 delay = 8 seconds
Level 4 delay = 12 seconds
Level 5 delay = 17.5 seconds
Level 6 delay = 25 seconds
Windshield Wiper Motor
The integrated park switch is directly connected to the BCM . The windshield wiper motor park switch
contacts are open in all wiper motor positions except PARK. When the windshield wiper motor park
switch contacts are open, the windshield wiper motor remains switched on even if a signal from the BCM
requests the wipers to stop. In PARK position, the windshield wiper motor park switch contacts create a
ground connection. The BCM recognizes this ground connection and switches the windshield wiper
motor off.
Front Washer System
When the front washer system is switched ON, the BCM switches the window washer pump ON. The
windshield and rear window wiper systems share the window washer pump and cannot be used
simultaneously. The BCM delays wiper operation for 360 ms after operation of the wiper/washer switch
washer setting. If the wiper/washer switch washer setting is not operated for at least 360 ms, the BCM
does not switch the windshield wiper motor ON. The BCM activates the windshield wiper motor for as
long as the wiper/washer switch washer setting is operated, up to 10 seconds maximum. After the
washer pump is turned OFF, the BCM allows the windshield wipers to wipe 4 more times. An additional
courtesy wipe follows the 4 wipes after a brief pause.
Rear Window Wiper System
The rear window wiper system only operates if the ignition is ON. The position that the wiper/washer
switch is in for the front windshield wipers determines the action of the rear wiper:
When the wiper/washer switch is in a position that commands the rear wiper ON and the front
windshield wipers are in the OFF position, the rear wiper is activated by the BCM with a 4 second
delay between wipes.
When the front windshield wipers are being operated in the intermittent mode, the rear wiper also
operates in the intermittent mode. The rear wiper reacts along with the front windshield wipers to
changes in the position of the rotary interval switch. When the rotary switch is positioned for a
long delay between wipes, the rear wiper also operates with a long delay between wipes. The
same is true for a short delay between wipes.
When the front windshield wipers are operated at normal speed, the rear wiper operates with a 4
second delay between wipes when switched on.
When the front windshield wipers are operated at high speed, the rear wiper operates
continuously when switched on.
Rear Washer System
When the rear wash system is switched ON, the BCM supplies power to the washer pump. Reversing
the polarity of the pump enables the washing fluid to flow to the rear washer jet instead of the front
washer jets. The BCM activates the window wiper for as long as the window washer switch is operated.
The window washer pump is switched OFF after a maximum of 10 seconds. After clearance from the
switch, the BCM allows the wiper to wipe 2 or 3 more times.
Rear Wiper Motor
The integrated park switch is directly connected to the BCM . The rear window wiper motor park switch
contacts are closed in all rear window wiper motor positions except PARK. When the rear window wiper
motor park switch contacts are closed, the rear window wiper motor is supplied with a voltage by the
BCM . When the rear window wiper motor reaches the PARK position, the park switch contacts open
and the power supply is interrupted by the BCM . While the wiper/washer switch remains in the rear
washer position, the rear window wiper motor is again supplied with a voltage by the BCM and continues
to run. This process is repeated during every revolution of the rear window wiper motor.

Refer to Wiring Diagrams Cell 81 , Wipers and Washers for schematic and connector information.
Normal Operation
Power is supplied from the Central Junction Box (CJB) to the Body Control Module (BCM) for the front
wiper system when the ignition is in the ON position. The BCM supplies a signal voltage(s) to the
wiper/washer switch for the HIGH speed, LOW speed, and INTERMITTENT functions. Each function
has its own dedicated signal (sense) voltage. The wiper/washer switch physically grounds the signal
voltage(s) when a function is selected. The BCM then reacts to the grounded signal voltage(s) and its
integral electronics make a decision on which wiper system function to carry out. Ground is supplied to
the wiper motor through a circuit that is shared by the BCM windshield wiper return circuit.

Pinpoint Test H: The Wipers Will Not PARK at the Correct Position — Windshield
Refer to Wiring Diagrams Cell 81 , Wipers and Washers for schematic and connector information.
Normal Operation
Integral to the wiper motor is a set of contacts that only close when the wipers are in the PARK position.
When closed the contacts supply ground to the Body Control Module (BCM) which uses the ground to
sense when the wipers are in the PARK position. If the wipers are in use, the BCM continues to supply
power to the wiper motor after the wipers are commanded OFF and in a NON-PARK position. Once the
wipers are in the PARK position, the BCM removes power from the wiper motor and the wipers remain
PARKED.

2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Safety Belt System
WARNING: After any crash, all of the following safety belt assemblies and attaching
hardware must be inspected to verify correct function:
Retractors
Buckles
Belt tension sensor (BTS) (if equipped)
Front safety belt buckle support assemblies (slide bar) (if equipped)
Safety belt shoulder belt height adjusters (if equipped)
Child safety seat tether bracket assemblies
Automatic locking retractor (ALR) feature for child safety seats (passenger seating
positions only)
If any safety belt assembly is damaged, does not operate correctly or does not pass all of the
Functional Tests in the Component Tests of this section, a new safety belt assembly must be
installed. If any safety belt assembly attaching areas are damaged or distorted, the sheet metal
must be restored to its original structural integrity and new safety belt assembly and attaching
hardware must be installed. Failure to install new safety belt assemblies and attaching hardware
may increase the risk of serious personal injury or death in a crash.
After any crash that results in deployment of the driver and/or front outboard passenger safety
belt pretensioners, new driver and/or front outboard passenger safety belt systems (including
retractors, buckles and height adjusters) must be installed. Failure to install new safety belt
systems increases the risk of serious personal injury or death in a crash.
Use only the replacement parts specified in the Ford Catalog Advantage™ or equivalent when installing
new safety belt buckles and/or retractor assemblies.
Active Restraint System Components
The active restraint system consists of the following serviceable items:
Front safety belt shoulder height adjusters
Front safety belt buckles attached to the inboard side of the seats
Front safety belt retractors and pretensioners (pretensioner feature available only on vehicles
equipped with Supplemental Restraint System (SRS)) located behind the lower B-pillar trim
panels
Rear center safety belt retractor attached to the parcel shelf sheet metal (4-door sedan) or LR
seat frame (5-door hatchback) and LH safety belt buckle assembly attached to the floor pan
under the rear seat cushion
Rear safety belt retractors (outboard) attached to the parcel shelf sheet metal (4-door sedan) or
C-pillars (5-door hatchback)
Rear dual safety belt buckle assembly (RH and center safety belt buckles) attached to the floor
pan
Child safety seat tether anchors located on the parcel shelf (4-door sedan) or on the back of the
second row seat back rest (5-door hatchback), at all 3 seating positions
Lower Anchors and Tethers for CHildren (LATCH) attached to the floor pan
Safety Belt Retractors
The safety belt retractors consist of the following components:
Safety belt retractor pretensioner (front only), on vehicles equipped with SRS
Adaptive load limiting (front passenger only), on vehicles equipped with SRS
Dual locking mode
Emergency Locking Retractor (ELR)
Automatic Locking Retractor (ALR) (all except driver seat)
Belt Tension Sensor (BTS) (front passenger only), on vehicles equipped with SRS
Automatic Locking Retractor (ALR)
The ALR mode is used when locking a child seat in any passenger seating position. The ALR mode
automatically activates when the safety belt webbing is fully extracted from the retractor and then
allowed to retract. As the safety belt webbing retracts back onto the spool, an audible clicking sound is
made indicating the safety belt retractor is in ALR mode and the safety belt webbing will not pull back out
of the safety belt retractor. The ALR mode disengages when the webbing is allowed to fully retract back
into the retractor. For testing, refer to the appropriate Functional Test procedure in Safety Belt System in
this section.
Safety Belt Retractor Pretensioner
The safety belt retractor pretensioner is a pyrotechnic device that removes excess webbing from the
safety belt system when deployed by the SRS . When the pretensioner deploys, the retractor spools in
the safety belt webbing, removing excess webbing from the lap and shoulder safety belts.
If the vehicle is involved in a crash resulting in pretensioner deployment, install a new safety belt
retractor pretensioner. For safety belt retractor pretensioner diagnosis and disposal information, refer to
Section 501-20B .
If the ignition is ON with the safety belt retractor pretensioner electrical connector(s) disconnected, a
DTC sets.
The pretensioner feature is only available on the front safety belt retractors of SRS -equipped vehicles.
Adaptive Load Limiting
Adaptive load limiting safety belt retractors are pyrotechnic devices integrated with the front passenger
safety belt retractor assembly. The adaptive load limiting safety belt retractor works in conjunction with
the safety belt pretensioner to control the tension of the front passenger safety belt. The Restraints
Control Module (RCM) monitors the readiness of the adaptive load limiting safety belt retractor. The
RCM uses this information and all other information provided by the restraints system to determine what
action is to be taken.
The adaptive load limiting pyrotechnic device feature is only available on the front passenger safety belt
retractors of SRS -equipped vehicles.
Emergency Locking Retractor (ELR)
The ELR is a vehicle-sensitive feature designed to activate and lock the safety belt webbing during hard
braking, cornering hard or in an impact of approximately 24 km/h (15 mph). The ELR feature helps
reduce the forward movement of the driver and passengers. For testing, refer to the appropriate
Functional Test procedure in Safety Belt System in this section.
Belt Tension Sensor (BTS)
The BTS is located at the front passenger safety belt retractor anchor point and operates as part of the
Occupant Classification System (OCS) system on the front passenger seat. To diagnose the BTS , refer
to Section 501-20B .
Safety Belt Buckles
Front Safety Belt Buckles
The front seat safety belt buckles are attached to the front seat tracks.
On vehicles equipped with an SRS , the front safety belt buckles have a switch indicating buckle status
to the RCM . To diagnose the buckle switch, refer to Section 501-20B .
Rear Safety Belt Buckles
The rear seat safety belt buckles are attached to the floor pan under the rear seat cushion. The LH
safety belt buckle is part of the rear center safety belt retractor and is serviced as an assembly. The rear
dual safety belt buckle assembly (RH and center buckle) is also serviced as an assembly.
Child Safety Seat Restraints
The child safety seat restraints include the following items:
Serviceable child safety seat tether anchor located at the rear seating positions, bolted to the
parcel shelf sheet metal on 4-door sedans. On 5-door hatchbacks, the child safety seat tether
anchors are part of the second row seat back and are not serviced separately from the seat back.
Non-serviceable Lower Anchors and Tethers for CHildren (LATCH), welded to the floor pan.
If a child safety seat was in use during a collision, inspect the vehicle structure at the child safety seat
component mounting areas, repair any damage and restore the vehicle to the original production
configuration.

Principles of Operation
The Restraints Control Module (RCM) continuously receives/monitors all inputs from the following
Supplemental Restraint System (SRS) components:
LH and RH front impact severity sensors
Driver and passenger front door side impact sensor
Driver and passenger second row side impact sensors (C-pillar)
Safety belt buckle switches (driver and passenger)
Seat track position sensors (driver and passenger)
Occupant Classification System Module (OCSM)
Safing sensors internal to the RCM
If the RCM detects sudden vehicle deceleration and/or lateral deceleration based on the information received
from all sensors and switches and determines that deployment is required, the RCM sends voltage and current
to deploy the appropriate SRS components.
During a frontal or side crash, the RCM may deploy the following SRS components, based on crash severity
and sensor input.
Safety belt retractor pretensioner(s)
Safety belt load limiter (passenger side only)
Seat side air bag(s)
Side air curtain(s)
Driver and passenger dual-stage air bag(s) (one or both stages)
Driver knee air bag
The fact that the safety belt retractor pretensioner, safety belt load limiter, side air curtain, or air bags did not
activate for both front seat occupants in a crash does not mean that something is wrong with the system.
The RCM performs a self-test of the complete SRS during each start up. If a SRS fault exists, the air bag
warning indicator illuminates and remains illuminated for the rest of the ignition cycle. In addition to the self-test
at start up, the RCM continuously monitors all of its SRS components and circuitry for correct operation.
Air Bag Warning Indicator
The air bag warning indicator:
located in the Instrument Panel Cluster (IPC), proves out by illuminating for 6 seconds and then turning
off.
flashes and/or illuminates based on the message the IPC receives from the RCM .
illuminates if the IPC does not receive a message from the RCM .
Air Bag Module Second Stage Deployment Check
Because the driver and passenger front air bags each have 2 deployment stages, it is possible that stage 1 has
deployed and stage 2 has not.
If a front air bag module has deployed, it is mandatory the front air bag module be remotely deployed using the
appropriate air bag disposal procedure.
For information on driver air bag module and/or passenger air bag module remote deployment, refer to
Pyrotechnic Device Disposal in this section.
Clockspring
The clockspring allows for continuous electrical connections between the driver air bag module and the RCM
when the steering wheel is turned.
Driver Air Bag Module
The driver air bag module is a dual-stage air bag, upon receiving a flow of current from the RCM , deploying at
1 of 2 different rates depending upon vehicle impact severity and sensor input.
High Speed Controller Area Network (HS-CAN)
This vehicle utilizes a communication system called a High Speed Controller Area Network (HS-CAN). The
RCM communicates with various modules for required information about the vehicle. Refer to Section 418-00
for additional information about the HS-CAN .
Occupant Classification System (OCS) System
The Occupant Classification System (OCS) system is found only on the front passenger seat. The OCS system
classifies the size of front passenger seat occupant and provides this information to the Restraints Control
Module (RCM). The RCM uses this information (and other inputs) in determining the deployment strategy of the
passenger air bag and safety belt pretensioner.
The OCS system is also used for operation of the passenger Belt-Minder®. For information on the passenger
Belt-Minder® feature, refer to Section 413-01 or the Owner's Literature.
The OCS system consists of:
a silicone gel-filled bladder mounted between the seat cushion foam and pan
a pressure sensor that is mounted to the seat frame
an OCSM mounted to the seat frame
Pressure is applied to the OCS system bladder when weight of any occupant or object in the front passenger
seat is present. The pressure is then transferred through a tube, sensed by the OCS system pressure sensor,
then electronically communicated to the OCSM . The components of an OCS bladder system (bladder,
pressure sensor and tube, OCSM ) are serviced as an assembly.
Belt Tension Sensor (BTS)
The Belt Tension Sensor (BTS):
is a 3-wire Hall-effect sensor located at the safety belt anchor point and is part of the front passenger
safety belt and retractor assembly.
is used in conjunction with the OCS system.
The BTS is used by the OCS system to identify the presence of a child safety seat on the front passenger seat.
The BTS senses the tension on the safety belt assembly then provides an output to the OCSM , indicating the
safety belt assembly is cinched. After sensing the weight applied to the seat by the occupant and using the BTS
input, the OCSM determines how the occupant should be classified and communicates this information to the
RCM . If the occupant is classified as a child, the RCM automatically deactivates the passenger air bag module
and illuminates the Passenger Air Bag Deactivation (PAD) indicator.
Passenger Air Bag Deactivation (PAD) Indicator
The RCM controls the state of the PAD indicator through a direct, hard-wired connection, based on information
provided by the OCS system. The PAD indicator illuminates to indicate the passenger air bag module is
disabled. An exception to this is when the front passenger seat is determined to be empty and indication of a
deactivated passenger air bag module is not necessary. In all other cases, the PAD indicator is off when the
passenger air bag module is enabled.
The RCM briefly activates the PAD indicator to prove-out the indicator function and verify to the front occupants
that the PAD indicator is operating correctly.
The following table indicates the passenger air bag and PAD indicator status based on the size of the front
passenger occupant.

Passenger Air Bag Module
The passenger air bag module is a dual-stage air bag, deploying at 1 of 2 different rates depending upon
vehicle impact severity and sensor input.
Restraints Control Module (RCM)
WARNING: Do not handle, move or change the original horizontal mounting position of the
restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to
follow this instruction may result in the accidental deployment of the Safety Canopy® and cause
serious personal injury or death.
WARNING: If a vehicle has been in a crash, inspect the restraints control module (RCM) and the
impact sensor (if equipped) mounting areas for deformation. If damaged, restore the mounting areas to
the original production configuration. A new RCM and sensors must be installed whether or not the air
bags have deployed. Failure to follow these instructions may result in serious personal injury or death
in a crash.
NOTE: This vehicle may be equipped with the SYNC® feature which contains the 911 assist option. For
additional information, refer to Owner's Literature.
The RCM carries out the following functions:
deploys the air bag(s)/safety curtains in the event of a deployable collision
activates the safety belt retractor pretensioners to remove slack from the safety belts in the event of a
deployable collision
activates the passenger retractor to control the tension of the passenger safety belt in the event of a
deployable collision
monitors the SRS for faults
sends a message to the IPC to illuminate the air bag warning indicator if a fault is detected
The RCM monitors the SRS for possible faults. If a fault is detected, the RCM requests the IPC to illuminate the
air bag warning indicator. When the ignition is turned OFF and then ON, the IPC proves out the air bag warning
indicator by illuminating it for 6 seconds. If no faults are detected by the RCM , the IPC turns the air bag
warning indicator off and it remains off. If the RCM detects a fault, it sends a message to the IPC to illuminate
the air bag warning indicator and it remains illuminated for the rest of the ignition cycle. If the RCM requests
illumination of the air bag warning indicator and the air bag warning indicator does not function, the IPC
automatically activates an audible chime. The chime is a series of 5 sets of 5 tone bursts. If the chime is heard,
the SRS and the air bag warning indicator require repair.
The RCM includes a backup power supply. This feature provides sufficient backup power to deploy the air bags
in the event the ignition circuit is lost or damaged during impact. The backup power supply depletes its stored
energy approximately one minute after power and/or ground has been removed from the RCM .
Event Notification Signal
The deployment event notification signal provides other vehicle subsystems with information pertaining to
restraint system deployment or fuel cutoff status. Signal communication between the RCM and fuel pump relay
allows the PCM to initiate fuel cut-off to disable the fuel system in the event of a crash.
The RCM does not monitor the event notification signal circuit for faults and will not set a DTC if a fault occurs.
Safety Belt Buckle Switches
The safety belt buckles contain integrated circuits called Hall-effect switches. The safety belt buckle switches
indicate to the RCM whether the safety belts are buckled or unbuckled.
The RCM also communicates the status of each safety belt buckle switch to the IPC , which monitors the
information to control the safety belt warning indicator. For information on the safety belt warning indicator, refer
to Section 413-01 .
Safety Belt Retractor Pretensioners
The safety belt retractor pretensioners remove excess slack from the safety belt webbing. The pretensioners
are activated by the RCM when the module detects a crash event force exceeding a programmed limit.
Safety Belt Retractor
The front passenger safety belt retractor is equipped with the adaptive load limiting feature that controls the
tension of the front passenger safety belt in the event of a crash. The adaptive load limiter is activated by the
RCM . The driver safety belt retractor is equipped with a non-deployable (mechanical) load limiter. The front
safety belt retractor may also be referred to as a seatbelt load limiter.
Side Air Curtain Modules
WARNING: Anytime the Safety Canopy® or side air curtain module has deployed, a new headliner
and new A-, B- and C-pillar upper trim panels and attaching hardware must be installed. Remove any
other damaged components and hardware and install new components and hardware as needed.
Failure to follow these instructions may result in the Safety Canopy® or side air curtain module
deploying incorrectly and increases the risk of serious personal injury or death in a crash.
The side air curtain module:
deploys upon receiving a flow of current from the RCM , initiated by the RCM .
is installed as an assembly.
is mounted above the headliner.
attaches from the A-pillar frame to the C-pillar frame.
Seat Track Position Sensors
The seat track position sensors indicate the position of the driver and passenger seats along the seat track to
the RCM . The sensor detects the presence of a shunt bracket on the track, indicating that the seat has moved
forward beyond a certain point of adjustment. The RCM uses seat track position sensor information to
determinine the deployment rate of the dual-stage driver air bag and/or passenger air bag module(s).
Secondary Air Bag Warning (Chime)
The secondary air bag warning chime is an audible chime located in and controlled by the IPC . If a fault is
detected with the air bag warning indicator, a DTC is stored in IPC memory. Upon receiving the message from
the RCM that a SRS fault has been detected, the IPC sounds the secondary air bag warning chime in a pattern
of 5 sets of 5 beeps.
Impact Sensors
In addition to the RCM , the SRS uses 6 satellite impact sensors. The RCM is mounted to the center tunnel
beneath the floor console. All vehicles have 2 front impact severity sensors (frontal restraints sensor), 2 first row
(front door) impact sensors (side restraints sensor 1), and 2 second row impact sensors (side restraints sensor
2). The front impact severity sensors are located in the front of the vehicle, behind the bumper. The front door
impact sensors are mounted behind each front door trim panel and each second row sensor is located on each
C-pillar. Mounting orientation is critical for correct operation of all impact sensors.
Seat Side Air Bag Modules
The seat side air bag module:
deploys upon receiving a flow of current from the RCM , initiated by the side restraints sensor and
internal RCM circuitry.
is mounted in the seat backrest.
is used in conjunction with a side air curtain module.
Driver Knee Bolster Air Bag Module
The driver knee bolster air bag module is part of the steering column opening trim panel and deploys upon
receiving a flow of current from the RCM .
Fault Reporting
There are 2 types of fault reporting that can be utilized by the OCSM . The first type, considered conventional,
has only one level of fault reporting and identifies a specific concern for a given component and points to a
particular diagnostic path (for example, DTC B1317 (Battery Voltage High)).
The second type uses a process within the software of the controller that maps the byte and bit to name a
specific device and fault condition. This process is called Bit-mapping and referred to as fault PIDs in the
diagnosis of the vehicle. This type does not identify the specific concern or component on the first level of fault
reporting (for example, DTC B2290 (Occupant Classification System Fault)). DTC B2290 can have up to 3
specific on-demand fault PIDs (areas of concern) associated with this DTC.
The RCM does not utilize fault PIDs for this vehicle.
Those associated fault PIDs are an extension of the information provided by the DTC and are identified by the
same DTC number. Use a scan tool to view DTCs and their fault PIDs. Once a scan tool has retrieved a DTC,
use the scan tool to view the fault PIDs. In the diagnostic path, other types of PIDs are sometimes used to
determine the root cause (for example, resistance or voltage PIDs).
When viewing of fault PIDs has been carried out, the scan tool can display the PIDs associated with that DTC,
including the status or state that exists (on-demand [active] DTC) or existed (continuous memory [historic])
DTC. Refer to the scan tool manufacturer's instructions for the scan tool being used on how to view fault PIDs.
Inspection and Verification
1. Verify the customer concern by checking the air bag warning indicator in the IPC . Refer to Prove Out the
System in this section.
With the ignition OFF, wait 10 seconds, then turn the ignition ON and monitor the air bag warning
indicator with the air bag modules installed. The air bag warning indicator illuminates continuously for
approximately 6 seconds and then turns off. If an air bag SRS fault is detected, the air bag warning
indicator indicates the fault in one of the following ways:
— fails to light
— remains lit continuously
— flashes
The flashing might not occur until approximately 30 seconds after the ignition has been turned from OFF
to ON. This is the time required to complete testing of the SRS . If the air bag warning indicator is
inoperative and a SRS fault exists, a chime will sound in a pattern of 5 sets of 5 beeps. If this occurs, the
diagnose and repair the air bag warning indicator and any SRS fault discovered.
2. Visually inspect for obvious signs of mechanical or electrical damage. Do not disconnect electrical
connectors until directed to do so within the pinpoint test.

5. NOTE: The Vehicle Communication Module (VCM) LED prove-out confirms power and ground from the
DLC are provided to the VCM .
If the scan tool does not communicate with the VCM :
check the VCM connection to the vehicle.
check the scan tool connection to the VCM .
refer to Section 418-00 , No Power To The Scan Tool, to diagnose no power to the scan tool.
6. If the scan tool does not communicate with the vehicle:
verify the ignition is ON.
verify the scan tool operation with a known good vehicle.
refer to Section 418-00 to diagnose no response from the PCM.
7. Carry out the network test.
If the scan tool responds with no communication for one or more modules, refer to Section 41800 .
If the network test passes, retrieve and record on-demand and Continuous Memory Diagnostic
Trouble Codes (CMDTCs) from the RCM and OCSM .
8. If the DTCs retrieved are related to the concern, go to the Restraints Control Module (RCM) DTC Chart
or Occupant Classification System Module (OCSM) DTC Chart. For all other DTCs, refer to Section 41910 .
9. If no DTCs related to the concern are retrieved, GO to Symptom Chart .
DTC Charts
NOTE: Refer to Description and Operation, Intelligent Access with Push Button Start in Section 419-01B to
review the procedures for achieving the various ignition states on vehicles with this feature.
The DTCs can be retrieved from the RCM and the OCSM with a scan tool via the DLC .
Restraints Control Module (RCM) DTC Chart
NOTE: Always make sure the correct Supplemental Restraint System (SRS) component is being installed.
Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part
number listed in the Ford Catalog Advantage™ or equivalent to make sure the correct component is being
installed. If an incorrect SRS component is installed, DTCs may set.
NOTE: Network DTCs (U-codes) are often a result of intermittent concerns such as damaged wiring or low
battery voltage occurrences. Additionally, vehicle repair procedures such as module reprogramming often set
network DTCs. Replacing a module to resolve a network DTC is unlikely to resolve the concern. To prevent
repeat network DTC concerns, inspect all network wiring, especially connectors. Test the vehicle battery, refer
to Section 414-01 .
NOTE: This module utilizes a 5-character DTC followed by a 2-character failure type code. The failure type
code provides information about specific fault conditions such as opens or shorts to ground. Continuous
Memory Diagnostic Trouble Codes (CMDTCs) have an additional 2-character DTC status code suffix to assist
in determining DTC history.

Pinpoint Test — Restraints Control Module (RCM)
Pinpoint Test A: DTCs B0001:11, B0001:12, B0001:13 and B0001:1A
Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.
Normal Operation
The Restraints Control Module (RCM) continuously monitors the driver air bag module stage 1 circuits for the
following faults:
Resistance out of range
Unexpected voltage
Short to ground
Faulted driver air bag module
If a fault is detected, the RCM stores DTC B0001:11, B0001:12, B0001:13 or B0001:1A in memory and sends a
message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.
The RCM analyzes the deployment loop resistance and uses this measurement in combination with an age
correction factor to determine if a fault exists. The value displayed in the PID is the deployment loop resistance
as measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram
below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the
chance for a DTC increases. The RCM fault trigger threshold may vary as the vehicle ages. Small variations in
resistance can occur due to the effect of road vibrations on terminal fit and/or temperature changes. These
variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the
desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC
at time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a
repeat concern. This test uses a process of elimination to diagnose each part of the deployment loop circuit
including:
Wiring
Connections
Clockspring
Driver air bag module
RCM
DTC Description
Fault Trigger Condition
B0001:11 — Driver Frontal Stage 1

RCM
PINPOINT TEST A: DTCs B0001:11, B0001:12, B0001:13 AND B0001:1A
WARNING: Do not handle, move or change the original horizontal mounting position of the
restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to
follow this instruction may result in the accidental deployment of the Safety Canopy® and cause
serious personal injury or death.
WARNING: Never probe the electrical connectors on air bag, Safety Canopy® or side air curtain
modules. Failure to follow this instruction may result in the accidental deployment of these modules,
which increases the risk of serious personal injury or death.
NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure
to use the correct probe adapter(s) may damage the connector.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and
verification before proceeding with the pinpoint test.
NOTE: Only disconnect or reconnect Supplemental Restraint System (SRS) components when
instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect
diagnosis of the SRS .
NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may
not be compatible even if they appear physically similar. Check the part number listed in the Ford Catalog
Advantage™ or equivalent to make sure the correct component is being installed. If an incorrect SRS
component is installed, DTCs may set.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Pinpoint Test B: DTCs B0002:11, B0002:12, B0002:13 and B0002:1A
Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.
Normal Operation
The Restraints Control Module (RCM) continuously monitors the driver air bag module stage 2 circuits for the
following faults:
Resistance out of range
Unexpected voltage
Short to ground
Faulted driver air bag module
If a fault is detected, the RCM stores DTC B0002:11, B0002:12, B0002:13 or B0002:1A in memory and sends a
message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.
The RCM analyzes the deployment loop resistance and uses this measurement in combination with an age
correction factor to determine if a fault exists. The value displayed in the PID is the deployment loop resistance
as measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram
below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the
chance for a DTC increases. The RCM fault trigger threshold may vary as the vehicle ages. Small variations in
resistance can occur due to the effect of road vibrations on terminal fit and/or temperature changes. These
variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the
desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC
at time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a
repeat concern. This test uses a process of elimination to diagnose each part of the deployment loop circuit
including:
Wiring
Connections
Clockspring
Driver air bag module
RCM
DTC Description
Fault Trigger Condition
B0002:11 — Driver Frontal Stage 2

PINPOINT TEST B: DTCs B0002:11, B0002:12, B0002:13 AND B0002:1A
WARNING: Do not handle, move or change the original horizontal mounting position of the
restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to
follow this instruction may result in the accidental deployment of the Safety Canopy® and cause
serious personal injury or death.
WARNING: Never probe the electrical connectors on air bag, Safety Canopy® or side air curtain
modules. Failure to follow this instruction may result in the accidental deployment of these modules,
which increases the risk of serious personal injury or death.
NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure
to use the correct probe adapter(s) may damage the connector.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and
verification before proceeding with the pinpoint test.
NOTE: Only disconnect or reconnect Supplemental Restraint System (SRS) components when
instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect
diagnosis of the SRS .
NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may
not be compatible even if they appear physically similar. Check the part number listed in the Ford Catalog
Advantage™ or equivalent to make sure the correct component is being installed. If an incorrect SRS
component is installed, DTCs may set.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.
Normal Operation
The Restraints Control Module (RCM) continuously monitors the driver knee bolster air bag module circuits for
the following faults:
Resistance out of range
Unexpected voltage
Short to ground
Faulted driver knee bolster air bag module
If a fault is detected, the RCM stores DTC B0004:11, B0004:12, B0004:13 or B0004:1A in memory and sends a
message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.
The RCM analyzes the deployment loop resistance and uses this measurement in combination with an age
correction factor to determine if a fault exists. The value displayed in the PID is the deployment loop resistance
as measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram
below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the
chance for a DTC increases. The RCM fault trigger threshold may vary as the vehicle ages. Small variations in
resistance can occur due to the effect of road vibrations on terminal fit and/or temperature changes. These
variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the
desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC
at time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a
repeat concern. This test uses a process of elimination to diagnose each part of the deployment loop circuit
including:

follow this instruction may result in the accidental deployment of the Safety Canopy® and cause
serious personal injury or death.
WARNING: Never probe the electrical connectors on air bag, Safety Canopy® or side air curtain
modules. Failure to follow this instruction may result in the accidental deployment of these modules,
which increases the risk of serious personal injury or death.
NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure
to use the correct probe adapter(s) may damage the connector.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and
verification before proceeding with the pinpoint test.
NOTE: Only disconnect or reconnect Supplemental Restraint System (SRS) components when
instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect
diagnosis of the SRS .
NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may
not be compatible even if they appear physically similar. Check the part number listed in the Ford Catalog
Advantage™ to make sure the correct component is being installed. If an incorrect SRS component is installed,
DTCs may set.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Pinpoint Test E: DTCs B0011:11, B0011:12, B0011:13 and B0011:1A
Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.
Normal Operation
The Restraints Control Module (RCM) continuously monitors the passenger air bag module 2 circuits for the
following faults:
Resistance out of range
Unexpected voltage
Short to ground
Faulted passenger air bag module
If a fault is detected, the RCM stores DTC B0011:11, B0011:12, B0011:13 or B0011:1A in memory and sends a
message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.
The RCM analyzes the deployment loop resistance and uses this measurement in combination with an age
correction factor to determine if a fault exists. The value displayed in the PID is the deployment loop resistance
as measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram
below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the
chance for a DTC increases. The RCM fault trigger threshold may vary as the vehicle ages. Small variations in
resistance can occur due to the effect of road vibrations on terminal fit and/or temperature changes. These
variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the
desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC
at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create
a repeat concern. This test uses a process of elimination to diagnose each part of the deployment loop circuit
including:
Wiring
Connections
Passenger air bag module
RCM
DTC Description
Fault Trigger Conditions
B0011:11 — Passenger Frontal Stage 2
Deployment Control: Circuit Short to
Ground
When the RCM senses a short to ground on either
passenger frontal stage 2 deployment control circuit, a fault
is indicated.
B0011:12 — Passenger Frontal Stage 2
Deployment Control: Circuit Short to
Battery
When the RCM senses a short to voltage on either
passenger frontal stage 2 deployment control circuit, a fault
is indicated.
B0011:13 — Passenger Frontal Stage 2
Deployment Control: Circuit Open
When the RCM measures more than the desired resistance
range between passenger frontal stage 2 deployment
control circuits, a fault is indicated.
B0011:1A — Passenger Frontal Stage 2
Deployment Control: Circuit Resistance
Below Threshold
When the RCM measures less than the desired resistance
range between passenger frontal stage 2 deployment
control circuits, a fault is indicated.
This pinpoint test is intended to diagnose the following:
Wiring, terminals or connectors
Passenger air bag module
RCM
PINPOINT TEST E: DTCs B0011:11, B0011:12, B0011:13 AND B0011:1A
WARNING: Do not handle, move or change the original horizontal mounting position of the
restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to
follow this instruction may result in the accidental deployment of the Safety Canopy® and cause
serious personal injury or death.
WARNING: Never probe the electrical connectors on air bag, Safety Canopy® or side air curtain
modules. Failure to follow this instruction may result in the accidental deployment of these modules,
which increases the risk of serious personal injury or death.
NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure
to use the correct probe adapter(s) may damage the connector.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and
verification before proceeding with the pinpoint test.
NOTE: Only disconnect or reconnect Supplemental Restraint System (SRS) components when
instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect
diagnosis of the SRS .
NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may
not be compatible even if they appear physically similar. Check the part number listed in the Ford Catalog
Advantage™ or equivalent to make sure the correct component is being installed. If an incorrect SRS
component is installed, DTCs may set.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Pinpoint Test F: DTCs B0020:11, B0020:12, B0020:13 and B0020:1A
Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.
Normal Operation
The Restraints Control Module (RCM) continuously monitors the driver seat side air bag module circuits for the
following faults:
Resistance out of range
Unexpected voltage
Short to ground
Faulted driver seat side air bag module
If a fault is detected, the RCM stores DTC B0020:11, B0020:12, B0020:13 or B0020:1A in memory and sends a
message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.
The RCM analyzes the deployment loop resistance and uses this measurement in combination with an age
correction factor to determine if a fault exists. The value displayed in the PID is the deployment loop resistance
as measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram
below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the
chance for a DTC increases. The RCM fault trigger threshold may vary as the vehicle ages. Small variations in
resistance can occur due to the effect of road vibrations on terminal fit and/or temperature changes. These
variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the
desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC
at time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a
repeat concern. This test uses a process of elimination to diagnose each part of the deployment loop circuit
including:

WARNING: Do not handle, move or change the original horizontal mounting position of the
restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to
follow this instruction may result in the accidental deployment of the Safety Canopy® and cause
serious personal injury or death.
WARNING: Never probe the electrical connectors on air bag, Safety Canopy® or side air curtain
modules. Failure to follow this instruction may result in the accidental deployment of these modules,
which increases the risk of serious personal injury or death.
WARNING: Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive
load limiting retractors, safety belt inflators, or probe the electrical connectors. Failure to follow this
instruction may result in the accidental deployment of the safety belt pretensioners, adaptive load
limiting retractors, or safety belt inflators, which increases the risk of serious personal injury or death.
NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure
to use the correct probe adapter(s) may damage the connector.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and
verification before proceeding with the pinpoint test.
NOTE: Only disconnect or reconnect Supplemental Restraint System (SRS) components when
instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect
diagnosis of the SRS .
NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may
not be compatible even if they appear physically similar. Check the part number listed in the Ford Catalog
Advantage™ or equivalent to make sure the correct component is being installed. If an incorrect SRS
component is installed, DTCs may set.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Pinpoint Test G: DTCs B0021:11, B0021:12, B0021:13 and B0021:1A
Normal Operation
The Restraints Control Module (RCM) continuously monitors the driver side air curtain circuits for the following
faults:
Resistance out of range
Unexpected voltage
Short to ground
Faulted driver side air curtain
If a fault is detected, the RCM stores DTC B0021:11, B0021:12, B0021:13 or B0021:1A in memory and sends a
message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.
The RCM analyzes the deployment loop resistance and uses this measurement in combination with an age
correction factor to determine if a fault exists. The value displayed in the PID is the deployment loop resistance
as measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram
below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the
chance for a DTC increases. The RCM fault trigger threshold may vary as the vehicle ages. Small variations in
resistance can occur due to the effect of road vibrations on terminal fit and/or temperature changes. These
variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the
desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC
at time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a
repeat concern. This test uses a process of elimination to diagnose each part of the deployment loop circuit
including:

modules. Failure to follow this instruction may result in the accidental deployment of these modules,
which increases the risk of serious personal injury or death.
NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure
to use the correct probe adapter(s) may damage the connector.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and
verification before proceeding with the pinpoint test.
NOTE: Only disconnect or reconnect Supplemental Restraint System (SRS) components when
instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect
diagnosis of the SRS .
NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may
not be compatible even if they appear physically similar. Check the part number listed in the Ford Catalog
Advantage™ or equivalent to make sure the correct component is being installed. If an incorrect SRS
component is installed, DTCs may set.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Pinpoint Test I: DTCs B0029:11, B0029:12, B0029:13 and B0029:1A
Normal Operation
The Restraints Control Module (RCM) continuously monitors the passenger side air curtain circuits for the
following faults:
Resistance out of range
Unexpected voltage
Short to ground
Faulted passenger side air curtain
If a fault is detected, the RCM stores DTC B0029:11, B0029:12, B0029:13 or B0029:1A in memory and sends a
message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.
The RCM analyzes the deployment loop resistance and uses this measurement in combination with an age
correction factor to determine if a fault exists. The value displayed in the PID is the deployment loop resistance
as measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram
below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the
chance for a DTC increases. The RCM fault trigger threshold may vary as the vehicle ages. Small variations in
resistance can occur due to the effect of road vibrations on terminal fit and/or temperature changes. These
variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the
desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC
at time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a
repeat concern. This test uses a process of elimination to diagnose each part of the deployment loop circuit
including:
Wiring
Connections
Passenger side air curtain module
RCM
DTC Description
Fault Trigger Conditions
B0029:11 — Right Curtain Deployment
Control 1: Circuit Short to Ground
When the RCM senses a short to ground on either
passenger side air curtain circuit, a fault is indicated.
B0029:12 — Right Curtain Deployment
Control 1: Circuit Short to Battery
When the RCM senses a short to voltage on either
passenger side air curtain circuit, a fault is indicated.
B0029:13 — Right Curtain Deployment
Control 1: Circuit Open
When the RCM measures more than the desired resistance
range between the passenger side air curtain circuits, a
fault is indicated.
B0029:1A — Right Curtain Deployment
Control 1: Circuit Resistance Below
Threshold
When the RCM measures less than the desired resistance
range between the passenger side air curtain circuits, a
fault is indicated.
This pinpoint test is intended to diagnose the following:
Wiring, terminals or connectors
Passenger side air curtain module
RCM
PINPOINT TEST I: DTCs B0029:11, B0029:12, B0029:13 AND B0029:1A
WARNING: Do not handle, move or change the original horizontal mounting position of the
restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to
follow this instruction may result in the accidental deployment of the Safety Canopy® and cause
serious personal injury or death.
WARNING: Never probe the electrical connectors on air bag, Safety Canopy® or side air curtain
modules. Failure to follow this instruction may result in the accidental deployment of these modules,
which increases the risk of serious personal injury or death.
NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure
to use the correct probe adapter(s) may damage the connector.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and
verification before proceeding with the pinpoint test.
NOTE: Only disconnect or reconnect Supplemental Restraint System (SRS) components when
instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect
diagnosis of the SRS .
NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may
not be compatible even if they appear physically similar. Check the part number listed in the Ford Catalog
Advantage™ or equivalent to make sure the correct component is being installed. If an incorrect SRS
component is installed, DTCs may set.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.
Normal Operation
The Restraints Control Module (RCM) continuously monitors the passenger safety belt load limiter circuits for
the following faults:
Resistance out of range
Unexpected voltage
Short to ground
Faulted passenger safety belt load limiter
If a fault is detected, the RCM stores DTC B0082:11, B0082:12, B0082:13 or B0082:1A in memory and sends a
message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.
The RCM analyzes the deployment loop resistance and uses this measurement in combination with an age
correction factor to determine if a fault exists. The value displayed in the PID is the deployment loop resistance
as measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram
below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the
chance for a DTC increases. The RCM fault trigger threshold may vary as the vehicle ages. Small variations in
resistance can occur due to the effect of road vibrations on terminal fit and/or temperature changes. These
variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the
desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC
at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create
a repeat concern. This test uses a process of elimination to diagnose each part of the deployment loop circuit
including:
Wiring
Connections

B0082:11 — Passenger Seatbelt Load
Limiter Deployment Control: Circuit Short to

PINPOINT TEST L: DTCs B0082:11, B0082:12, B0082:13 AND B0082:1A
WARNING: Do not handle, move or change the original horizontal mounting position of the
restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to
follow this instruction may result in the accidental deployment of the Safety Canopy® and cause
serious personal injury or death.
WARNING: Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive
load limiting retractors, safety belt inflators, or probe the electrical connectors. Failure to follow this
instruction may result in the accidental deployment of the safety belt pretensioners, adaptive load
limiting retractors, or safety belt inflators, which increases the risk of serious personal injury or death.
NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure
to use the correct probe adapter(s) may damage the connector.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and
verification before proceeding with the pinpoint test.
NOTE: Only disconnect or reconnect Supplemental Restraint System (SRS) components when
instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect
diagnosis of the SRS .
NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may
not be compatible even if they appear physically similar. Check the part number listed in the Ford Catalog
Advantage™ or equivalent to make sure the correct component is being installed. If an incorrect SRS
component is installed, DTCs may set.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.
Normal Operation
The Restraints Control Module (RCM) monitors the driver front door and passenger second row C-pillar side
impact sensors and circuits for the following faults:
Open circuit
Short to voltage
Short to ground
Faulted driver front door side impact sensor
Faulted passenger second row C-pillar side impact sensor
If a fault is detected, the RCM stores DTC B0091:11, B0091:93, B0097:11 or B0097:93 in memory and sends a
message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.
The RCM communicates with each impact sensor. If the RCM is unable to communicate with the sensor, a
DTC is stored in memory. A Continuous Memory Diagnostic Trouble Code (CMDTC) no operation (failure
type :93) can be set by a short to voltage on the return circuit of the impact sensor.
NOTE: A short to ground on either impact sensor feed circuit sets DTCs B0091:11 and B0097:11.
A short to voltage on either impact sensor feed or return circuit sets DTCs B0091:93 and B0097:93.

Pinpoint Test O: DTCs B0092:11, B0092:93, B0096:11 and B0096:93
Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.
Normal Operation
The Restraints Control Module (RCM) monitors the driver second row C-pillar and passenger front door side
impact sensors and circuits for the following faults:
Open circuit
Short to voltage
Short to ground
Faulted driver second row C-pillar side impact sensor
Faulted passenger front door side impact sensor
If a fault is detected, the RCM stores DTC B0092:11, B0092:93, B0096:11 or B0096:93 in memory and sends a
message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.
The RCM communicates with each impact sensor. If the RCM is unable to communicate with the sensor, a
DTC is stored in memory. A Continuous Memory Diagnostic Trouble Code (CMDTC) no operation (failure type
status :93) can be set by a short to voltage on the return circuit of the impact sensor.
NOTE: A short to ground on either impact sensor feed circuit sets DTCs B0092:11 and B0096:11.
A short to voltage on either impact sensor feed or return circuit sets DTCs B0092:93 and B0096:93.

follow this instruction may result in the accidental deployment of the Safety Canopy® and cause
serious personal injury or death.
WARNING: Never probe the electrical connectors on air bag, Safety Canopy® or side air curtain
modules. Failure to follow this instruction may result in the accidental deployment of these modules,
which increases the risk of serious personal injury or death.
WARNING: Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive
load limiting retractors, safety belt inflators, or probe the electrical connectors. Failure to follow this
instruction may result in the accidental deployment of the safety belt pretensioners, adaptive load
limiting retractors, or safety belt inflators, which increases the risk of serious personal injury or death.
NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure
to use the correct probe adapter(s) may damage the connector.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and
verification before proceeding with the pinpoint test.
NOTE: Only disconnect or reconnect Supplemental Restraint System (SRS) components when
instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect
diagnosis of the SRS .
NOTE: Always make sure the correct Supplemental Restraint System (SRS) component is being installed.

Normal Operation
The Restraints Control Module (RCM) continuously monitors the driver safety belt retractor circuits for the
following faults:
Resistance out of range
Unexpected voltage
Short to ground
Faulted driver safety belt retractor pretensioner
If a fault is detected, the RCM stores DTC B1211:11, B1211:12, B1211:13 or B1211:1A in memory and sends a
message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.
The RCM analyzes the deployment loop resistance and uses this measurement in combination with an age
correction factor to determine if a fault exists. The value displayed in the PID is the deployment loop resistance
as measured by the RCM . If the value displayed is lower or higher than the desired range (refer to the diagram
below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the
chance for a DTC increases. The RCM fault trigger threshold may vary as the vehicle ages. Small variations in
resistance can occur due to the effect of road vibrations on terminal fit and/or temperature changes. These
variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the
desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC
at time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a
repeat concern. This test uses a process of elimination to diagnose each part of the deployment loop circuit
including:

WARNING: Do not handle, move or change the original horizontal mounting position of the
restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to
follow this instruction may result in the accidental deployment of the Safety Canopy® and cause
serious personal injury or death.
WARNING: Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive
load limiting retractors, safety belt inflators, or probe the electrical connectors. Failure to follow this
instruction may result in the accidental deployment of the safety belt pretensioners, adaptive load
limiting retractors, or safety belt inflators, which increases the risk of serious personal injury or death.
NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure
to use the correct probe adapter(s) may damage the connector.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and
verification before proceeding with the pinpoint test.
NOTE: Only disconnect or reconnect Supplemental Restraint System (SRS) components when
instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect
diagnosis of the SRS .
NOTE: Always make sure the correct Supplemental Restraint System (SRS) component is being installed.
Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part
number listed in the Ford Catalog Advantage™ or equivalent to make sure the correct component is being
installed. If an incorrect SRS component is installed, DTCs may set.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

Normal Operation
The Restraints Control Module (RCM) monitors all deployable device and sensor circuits for a signal crosscoupled (short) between circuits. If the RCM detects a short between the circuits of one device and another
device, it stores a DTC for each of the signal-cross coupled faults in memory. The RCM sends a message to
the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator. When a normal loop fault is
present (one loop is either shorted to battery/ground, open circuit or low resistance), signal cross-coupled
diagnostics are not active. Once the normal loop fault is repaired, the signal cross-coupled diagnostics resume.

Normal Operation
The Restraints Control Module (RCM) supplies the stability/traction control system with the yaw rate, roll rate,
lateral and longitudinal accelerometer readings over a dedicated Controller Area Network (CAN) bus. If the
RCM detects a fault with communications with the ABS module or dedicated CAN bus circuits, it stores DTC
U0028:08 or U0028:88.
The RCM will not request the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator if either
DTC U0028:08 or U0028:88 sets. The air bag warning indicator remains off if either of these DTCs are set.
DTC U0028:08 (Vehicle Communication Bus A: Bus Signal / Message Failures) — When the RCM does
not receive dedicated CAN bus messages from the ABS module for 5 seconds, a fault is indicated. An
open dedicated CAN circuit, incorrect installed ABS module or loss of power and/or ground to the ABS
module also sets this DTC.
DTC U0028:88 (Vehicle Communication Bus A: Bus Off) — When the RCM detects the dedicated CAN
circuits are shorted to ground, shorted to voltage or shorted to each other, a fault is indicated.
The ABS module may set similar DTCs, U0151 (Lost Communication With Restraints Control Module) and
U0452 (Invalid Data Received From Restraints Control Module).

Normal Operation — Restraints Control Module (RCM)
The Restraints Control Module (RCM) continuously monitors the input voltage for correct operation. If the RCM
detects input voltage below 9.5 volts, it stores DTC U3003:16 in memory. If the RCM detects input voltage
above 20 volts, it stores DTC U3003:17 in memory. If the RCM sets DTC U3003:16 or U3003:17, it sends a
message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.
Normal Operation — Occupant Classification System Module (OCSM)
The Occupant Classification System Module (OCSM) continuously monitors the input voltage for correct
operation. If the OCSM detects input voltage below 8 volts, it stores DTC B1318 in memory. If the OCSM
detects input voltage above 17.2 volts, it stores DTC B1317 in memory. If the OCSM sets DTC B1317 or
B1318, it sends a fault message to the RCM . The RCM then sends a message to the IPC module to illuminate
the air bag warning indicator.

Pinpoint Test AB: DTC B2909
Refer to Wiring Diagrams Cell 46 , Supplemental Restraint System for schematic and connector information.
Normal Operation
The Belt Tension Sensor (BTS) operates in conjunction with the Occupant Classification System (OCS) system.
The OCS system interprets a variable voltage signal provided by the BTS to identify the possible presence of a
child safety seat in the front passenger seat. The voltage output of the BTS is proportional to the amount of
tension applied to the sensor by the belt. No tension on the belt returns a low voltage (approximately 0.95 volt)
to the Occupant Classification System Module (OCSM), while high tension returns a higher voltage
(approximately 3.8 volts) to the OCSM .
The OCSM monitors the BTS and circuitry for faults. If a fault is detected, the OCSM stores DTC B2909 in
memory and sends a message to the Restraints Control Module (RCM). The RCM stores DTC B00A0:09 in
memory and sends a message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.

WARNING: Never probe the electrical connectors on air bag, Safety Canopy® or side air curtain
modules. Failure to follow this instruction may result in the accidental deployment of these modules,
which increases the risk of serious personal injury or death.
WARNING: Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive
load limiting retractors, safety belt inflators, or probe the electrical connectors. Failure to follow this
instruction may result in the accidental deployment of the safety belt pretensioners, adaptive load
limiting retractors, or safety belt inflators, which increases the risk of serious personal injury or death.
NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure
to use the correct probe adapter(s) may damage the connector.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and
verification before proceeding with the pinpoint test.
NOTE: Only disconnect or reconnect Supplemental Restraint System (SRS) components when
instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect
diagnosis of the SRS .
NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may
not be compatible even if they appear physically similar. Check the part number listed in the Ford Catalog
Advantage™ or equivalent to make sure the correct component is being installed. If an incorrect SRS
component is installed, DTCs may set.

WARNING: Invisible ultraviolet and infrared rays emitted in welding can injure unprotected
eyes and skin. Always use protection such as a welder's helmet with dark-colored filter lenses of
the correct density. Electric welding will produce intense radiation, therefore, filter plate lenses
of the deepest shade providing adequate visibility are recommended. It is strongly recommended
that persons working in the weld area wear flash safety goggles. Also wear protective clothing.
Failure to follow these instructions may result in serious personal injury.
The correct equipment and settings must be used when welding mild or high-strength steel. Metal Inert
Gas (MIG) and Squeeze-Type Resistance Spot Welding (STRW) are the preferred methods. Surfaces
must be clean and free of foreign materials.
Correct eye protection must be worn.
The correct protective clothing should always be worn.
Adequate ventilation must be provided to avoid accumulation of poisonous gases.
A test weld should always be carried out on a test sample.
Use cleaning brushes and abrasive grinding wheels dedicated to the type of materials being
welded.
Follow equipment manufacturer's prescribed procedures and equipment settings for the type of
welder being used. ER70S-3 or ER70S-6 wire are typically used for MIG welding steel.
Disconnect the battery ground cable. Refer to Section 414-01 .
Disconnect on-vehicle modules and protect them from possible heat damage and electrical
currents when welding.
Corrosion protection must be restored whenever bare metal repairs are made. Refer to Restoring
Corrosion Protection Following Repair in this section.
Adequate power supply needs to be used to make sure of correct equipment performance.
Factory spot welds may be substituted with either STRW or MIG plug welds. Spot/plug welds
should equal factory welds in both location and quantity. Do not place a new spot weld directly
over an original weld location. Plug weld hole should equal 8 mm (0.31 in) diameter.
Vehicles equipped with optional safety canopy require removal of these components prior to any
welding procedures being carried out in the roof-line or body side areas of the vehicle. Refer to

The correct sealing of joints is essential to repairing the vehicle correctly. Sealers are used to prevent wind
noise, water leaks, exhaust fumes and dust from entering the vehicle. They also provide anti-corrosion barriers.
Sealers are applied to areas such as door and rear compartment hem flanges, wheelhouse, quarter outer, floor,
cowl, roof and other panel-to-panel attaching points. The following joint sealers are recommended for use
depending upon the application:
Seam Sealer — Heavy-bodied, non-sag adhesive/sealer for use on standing cosmetic seams, truck bed
seams, tooled door skin seams and floor pans.
Sealers should remain flexible after curing and must be paintable. Follow the manufacturer's directions for
correct application of these materials.
Any damage to originally sealed joints should be repaired by resealing. Along with attaching points of new
panels, open joints that require bridging of sealer to close a gap should be sealed using a heavy-bodied sealer.

Several considerations will determine viability of plastic repair procedure(s):
Is the damage cosmetic or structural?
Can the repair be carried out on the vehicle?
Is the part readily available?
Is component repair the most cost effective method?
Can the component be economically restored to original strength and appearance?
Will the repair provide for the fastest, highest quality repair?
Several types of plastic are in use for automotive application. However, all plastics will fall into 2 primary
categories of thermoplastic or thermosetting plastic.
Thermosetting Plastic
Generally, thermosetting plastics are made with 2-part thermosetting resins. When mixed together, heat is
generated, producing a cure that is irreversible. Because of this, thermosetting plastics will require the use of a
2-part adhesive for repair.
Sheet-Molded Composite (SMC)
Sheet-Molded Composite (SMC) is a type of thermosetting plastic that uses glass fibers or nylon fibers in
combination with thermosetting polyester resins. When fully cured, SMC is strong and rigid.
SMC is similar, but not identical, to fiberglass. Ford Motor Company uses SMC in components such as fenders,
hoods and liftgates.
Thermoplastic Compounds
Thermoplastic compounds are manufactured by a process that is reversible. Thermoplastics can be remolded
repeatedly by reheating. This characteristic of thermoplastics makes plastic welding a possible repair
alternative. A repair of thermoplastic compounds is still possible through the use of 2-part adhesive and filler
repair materials and reinforcements as needed. Thermoplastics are widely used in interior trim components,
wheel flares, body side cladding and bumper covers.
Polyolefin
Polyolefins fall into the family of thermoplastics with one unique characteristic: an oily or waxy feel to the
material when sanded or ground. Polyolefin lends itself very well to remolding through the use of heat. Because
of this, components made of this material lend themselves well to the possibility of plastic welding. Most
adhesive repair materials and paint will not bond to surface of a polyolefin unless an adhesion promoter
specially formulated for plastic is first applied to the exposed raw surface. Otherwise, polyolefins are repaired
like most other thermoplastics. Some typical uses of polyolefins are bumper covers, fan shrouds and wheel
housings.
Correct identification of the various types of plastic is necessary to select the appropriate repair method(s) to
carry out high quality plastic repairs. Refer to Plastics Identification in this section.

WARNING: Always refer to Material Safety Data Sheet (MSDS) when handling chemicals and wear
protective equipment as directed. Examples may include but are not limited to respirators and
chemically resistant gloves. Failure to follow these instructions may result in serious personal injury.
Structural Adhesives
Adhesives are used in a variety of applications. Typical uses for adhesives include roof panels, door skins and
quarter panels. Trim applications include body side mouldings, emblems, stationary glass and weatherstripping.
Combination sealer/adhesives are also used. Surface preparation is critical to a high quality repair. Following
the label instructions for the product is essential.
Work in a well-ventilated area and protect adjacent surfaces when working with adhesives. Carry out a trial fit,
mark and align the surfaces before bonding the materials together.
Seam sealers and corrosion protection may be necessary once the adhesive(s) has cured, depending on the
application. The following is a list of adhesives recommended for certain types of applications:
Metal Bonding Adhesive — For bonding cold-rolled steel, galvanized steel, aluminum and correctly
prepared E-coat. It is used for door skin and roof panel replacement and OEM structural adhesive
replacement.
Plastic Bonding Adhesive — For bonding a variety of plastics to plastics and plastics to primed, painted
or E-coated metals. Also for general purpose bonding of trim components.
Trim and Weatherstrip Adhesive — For use on body side moulding, emblems, trim, bumper impact strips
and carpeting.
NOTE: Ford Motor Company does not approve or recognize structural repair procedures using anything but
genuine Ford parts.
Structural repairs (frames, rails, aprons and body panels) carried out using other than Ford Motor Company
parts have not been tested. In addition, structural equivalence and corrosion protection cannot be assured.
Returning a vehicle to pre-accident condition can only be assured if repair procedures are carried out by skilled
technicians using genuine Ford Motor Company parts and approved methods.
Structural component repair procedures approved by Ford using genuine parts have been validated through
testing by Ford Motor Company engineers. Should alternative structural component repair procedures and/or
parts be used, repairers should be aware of the potential liability they incur.
NOTE: Corrosion protection needs to be restored whenever it is necessary to sand or grind through painted
surfaces or E-coat, or when bare metal repairs are made.
NOTE: Factory spot welds may be substituted with either resistance spot welds or Metal Inert Gas (MIG) plug
welds. Spot/plug welds should equal factory welds in both location and quantity. Do not place a new spot weld
directly over an original weld location. Plug weld hole should equal 8 mm (0.31 in) diameter.

regarding structural repairs (frames, rails, aprons and body panels) carried out using nongenuine Ford Motor Company parts or non-Ford-approved methods. In particular, Ford makes no
representations that the vehicle will meet any crash safety or anti-corrosion performance
requirement. Such parts and methods have not been tested by Ford, and may not meet Ford's
requirements for safety, performance, strength, quality, durability and corrosion protection.
Ford Motor Company bears no responsibility or liability of any kind if repairs are performed
using alternative structural component repair procedures and/or parts.
NOTE: On door shells that are manufactured with structural adhesives only, weld bonding door skins is
not recommended. Only metal bonding adhesive should be used.
NOTE: Weld-bonding is a method used to join metals using Squeeze-Type Resistance Spot Welding
(STRW) or Metal Inert Gas (MIG) welding and structural adhesive. The steps listed in this procedure
apply to both types of welding. STRW is the preferred method. MIG welding should only be used when
areas to be welded cannot be accessed using STRW -type machinery.
NOTE: Factory spot welds should be substituted with either resistance spot welds or MIG plug welds.
Spot/plug welds should equal factory welds in both location and quantity. Do not place a new spot weld
directly over an original weld location. Plug weld hole should equal 8 mm (0.31 in) diameter.
1. Verify the vehicle is dimensionally correct on a frame machine. Straighten if necessary.
2. Remove damaged panels with an air saw or air chisel. Remove only large portions of the
damaged panel. Avoid cutting into mating flanges or adjacent parts.
3. Drill out the spot welds using an appropriate spot-weld cutter and remove the remaining portions
of the panel to be replaced.
4. Prepare any damaged flanges on the vehicle using hammer and dolly.
5. Grind the mating surface of the original flanges no greater than 25 mm (0.98 in) where the metal
bonding adhesive will be applied.
Be sure to remove galvanizing on metal. Metal should have a shiny appearance.
Be careful not to damage the corners or thin the metal. The E-coat should also be removed
on the opposite side of the flange only where the spot welds are to be placed. Clean
surfaces with metal surface prep or equivalent.
6. Dry-fit and clamp the replacement service parts to verify a correct fit.
Remove the service part after verifying correct fit and alignment.
7. NOTE: The ends of welding clamps should be insulated on the ends using tape or similar material
when welding is carried out.
Follow manufacturer's prescribed welding procedures and settings. For additional information,
refer to Welding Precautions — Steel in this section.
8. Prepare the adhesive. Dispense a small amount of metal bonding adhesive from the cartridge to
make sure of an even flow of both components. Attach the mixing tip and dispense a mixing tip
length of adhesive to make sure of a correct mix ratio.
9. NOTE: Welding can be carried out anytime during the adhesive curing process, or after the
adhesive is fully cured. Welder settings will vary when welding through wet adhesive versus
welding through fully cured adhesive. Refer to welder manufacturer's recommended settings for
welding through fully cured adhesive. It is recommended to place a shunt weld in an area with no
adhesive to make sure of conductivity, particularly when welding through fully cured adhesive.
NOTE: Refer to the product label for handling and preparation instructions.
Create a test sample.
1. Prepare the metal and adhesive as described. Apply a 6-9 mm (0.23-0.35 in) bead of
adhesive and weld the sample.
2. Place the welded sample in a vice and carry out destructive weld tests by peeling the scrap
metal apart using large lock-type pliers. Measure the weld nugget to determine that the
nugget meets Ford weld nugget requirements. If the weld nugget does not meet required
size, adjust welder settings until the correct weld nugget size is achieved.
3. When the correct weld nugget size is achieved, the service part can be weld-bonded. For
additional information, refer to the weld nugget table in Specifications in this section.
10. Apply a 6-9 mm (0.23-0.35 in) bead of metal bonding adhesive to the vehicle prepared flange
surface.
11. Place the service part(s) in the correct position on the vehicle.
When positioned, do not pull the component away from the vehicle. If repositioning is
necessary, slide the service part(s). This will make sure of correct contact between the
components and adhesive.
12. Clamp evenly and tightly. The adhesive contains glass beads which will prevent over-clamping
the component.
13. NOTE: Refer to product label for cure times and handling instructions. Clamps may be removed
immediately after the component is welded.
Wipe excess adhesive from the panel before it cures.
14. Finish any cosmetic section seams with fiber-filled body filler. Rough sand the filler, apply
conventional body filler after the adhesive cures and block-sand the area.
15. Use seam sealer wherever a cosmetic seam sealer is required.
16. Mix and apply primer surfacer per Ford-approved paint recommendations.
17. Mix and apply basecoat per Ford-approved paint recommendations.
18. Mix and apply clearcoat per Ford-approved paint recommendations. Refinishing materials may be
force-dried following paint manufacturer's recommendations.

portions of the panel to be replaced.
2. After removing the damaged sheet metal panel(s), repair any damaged flanges on the vehicle
using a hammer and dolly.
3. Using an appropriate grinder, carefully grind around the entire receiving flange area following the
original welds. Be sure to remove all E-coat, paint or galvanized coating from the mating surfaces
of the joint.
Be sure to remove galvanizing on metal. Metal should have a shiny appearance.
Be careful not to damage the corners or thin the metal. The E-coat should also be removed
on the opposite side of the flange only where the spot welds are to be placed. Clean the
surface with metal surface prep or equivalent.
4. Repeat the procedure from Step 3 on the mating surface of the replacement service part(s).
5. Prepare the new service panel for plug welds.
Using the original panel as a reference, drill or punch 8 mm (0.31 in) diameter holes in the
exact number as the original spot welds. The holes should be positioned as close as
possible to the original spot weld locations, without lining up exactly on top of an original
spot weld site.
To make sure of correct weld performance, grind the immediate perimeter of the plug weld
hole. Grind only in the area of the plug weld; this will keep corrosion to a minimum.
6. Dry-fit and clamp the replacement service parts to verify a correct fit and alignment.
Remove the service part after verifying correct fit and alignment.
7. The vehicle prepared flange areas where plug welds will be located must be kept free of
adhesive. Apply 25 mm (0.98 in) tape to the plug weld areas to prevent contamination from the
adhesive.

Plastics Identification
WARNING: Always refer to Material Safety Data Sheet (MSDS) when handling chemicals and
wear protective equipment as directed. Examples may include but are not limited to respirators
and chemically resistant gloves. Failure to follow these instructions may result in serious
personal injury.
WARNING: Always wear protective equipment including eye protection with side shields,
and a dust mask when sanding or grinding. Failure to follow these instructions may result in
serious personal injury.
NOTE: Identification of the various plastic types is necessary to select the appropriate repair methods to
make high quality plastic repairs. Plastics can generally be broken down into 2 categories,
thermoplastics and thermosetting plastics. Thermoplastics can be remolded by heating. This makes
plastic welding a possible repair alternative.
1. NOTE: In some instances, a code or material designation is stamped indicating the plastic type.
Thermoplastics are solvent reactive. Types of thermoplastics include Thermoplastic Olefin (TPO),
Polyvinyl Chloride (PVC) and Acrylonitrile Butadiene Styrene (ABS). Polyolefins have an oily or
waxy appearance. Examples include some bumper covers, stone shields, fender aprons and fan
shrouds. Polyolefins require an adhesion promoter prior to carrying out any refinish procedure.
To determine if the part is a polyolefin, grind the damaged area in an out-of-sight area.
Grinding a polyolefin will melt and smear the plastic and leave a ragged edge. If the part is
non-polyolefin, the area will grind or sand smoothly, producing a powdery dust.

2. Polyolefin plastic can also be identified by placing a small sliver in a container of water, if the
sample floats, it is a polyolefin plastic. A non-polyolefin will sink when placed in a container of
water.
3. Generally, thermosetting plastics are rigid or semi-rigid. Sheet-Molded Composite (SMC) is
reinforced with glass and other fibers and are strong and rigid. SMC is used for large panels such
as hoods, liftgates, fenders and quarter panels.
A burn test can be a reliable method to determine if a plastic is a thermosetting plastic.
Extreme care must be exercised when using this method.
Apply an open flame to the corner of the damaged component. If the material
crystallizes and becomes hard, it is a thermosetting plastic.

Plastics Refinishing
All Components
WARNING: Always refer to Material Safety Data Sheet (MSDS) when handling chemicals and
wear protective equipment as directed. Examples may include but are not limited to respirators
and chemically resistant gloves. Failure to follow these instructions may result in serious
personal injury.
WARNING: Do not paint any air bag module trim covers or deployment doors. Paint may
cause the air bag to deploy incorrectly. Failure to follow this instruction may increase the risk of
serious personal injury or death in a crash.
NOTE: When using any Ford-approved refinishing product, it is recommended to stay within the same
paint system throughout the process. For example, do not use one manufacturer's primers and another
manufacturer's topcoats.
1. NOTE: Care must be used if applying heat to parts. Thermoplastics soften and tend to lose their
shape when heated.
The first step for any repair or refinish procedure is to identify the type of plastic. Is it
thermosetting or thermoplastic, grained or smooth? This will determine how it should be cleaned
and prepared for refinishing. For additional information, refer to Plastics Identification in this
section.
It is essential that the correct cleaner is used, depending on which painting system is
employed, solvent-based or water-based.
Clean part with warm water/mild detergent, then with plastic cleaner to remove wax,
silicone and other contaminants. Do not allow parts to remain wet for extended periods.
As a general rule, if water beads on the part, it requires additional cleaning as all the
manufacturing release agents have not been removed.
2. New parts may require baking in a spray booth or heating with heat lamps to release trapped
solvents or mold release agents used in the manufacturing processes.
Non-grained components
3. After cleaning, lightly sand with 600-grit or finer sandpaper. Remove sanding residue with plastic
cleaner and wipe dry.
Grained components
4. After cleaning, light use of a gray scuff pad is permissible providing the graining not be flattened.
Remove sanding residue with plastic cleaner and wipe dry.
All components
5. Apply a plastics adhesion promoter to any bare plastic part following manufacturer's
recommendation. Throughout the refinish procedure, any time bare plastic is exposed for any
reason, it is essential that adhesion promoter be reapplied to that area.
6. A sealer may be required to prevent wrinkling and lifting of the topcoat prior to carrying out the
refinish procedure.
7. Flexible and non-flexible components should be refinished separately as a flex additive may be
required when refinishing flexible parts (refer to the paint manufacturer's recommendation).
8. It is recommended to carry out refinishing of exterior components on-vehicle (after cut-in) to
control color match and blending to adjacent panels.
9. Proceed with the refinish process and follow the Ford-approved paint system procedures. Steps
may vary between paint manufacturers.

WARNING: Always wear protective equipment including eye protection with side shields,
and a dust mask when sanding or grinding. Failure to follow these instructions may result in
serious personal injury.
WARNING: Always refer to Material Safety Data Sheet (MSDS) when handling chemicals and
wear protective equipment as directed. Examples may include but are not limited to respirators
and chemically resistant gloves. Failure to follow these instructions may result in serious
personal injury.
1. In deciding whether to repair or install a new component, follow these guidelines.
Is a part readily available?
Can the damaged part be economically returned to its original strength and appearance, or
will the labor cost exceed the cost of a new component?
Will repair provide for the fastest, highest quality repair?
2. NOTICE: Never apply solvents such as lacquer thinner or reducer at any stage of plastic
repair. Solvents, cleaners and water are absorbed by many types of plastics and by the
glass fibers used for reinforcements. If this occurs, the plastic may swell in the area of
repair and cause the repair to fail. Remove cleaners and water quickly and use air and heat
to speed up drying.
NOTICE: During the repair of many plastics and particularly polyolefin plastics, an
adhesion promoter must be applied to the substrate to allow repair materials and paint to
bond correctly. Reapplication is required when grinding or sanding through the sealer or
primered layers.
NOTE: When possible, it is recommended to carry out as much of the plastic repair as possible
on the vehicle. Parts mounted on the vehicle are held in correct alignment throughout the repair.
Attempting to repair the part off the vehicle may cause misalignment. This could lead to failure of
the repair.
Select the correct repair method by identifying the type of plastic being repaired. For additional
information, refer to Plastics Identification in this section to determine the type of plastic being
repaired.
3. NOTE: Always refer to the manufacturer's label directions for the type of repair materials, fillers
and bonding agents being used as they are material specific.
Determine whether a reinforcement piece is needed as a backer on large repairs.
Construct a reinforcement piece from a scrap piece of the type of plastic being repaired
and follow manufacturer's label directions for the type of system being used.
When repairing Sheet-Molded Composite (SMC), a reinforcement piece can be
constructed using several layers of glass cloth saturated with resin or structural adhesive.
The weave of the cloth or screening should be loose enough to allow the resin to
thoroughly penetrate. Reinforcement should cover the entire area of damage and extend
outward beyond the damage or joint area.
Sheet-Molded Composite (SMC) Panel Repair
NOTE: The following procedure applies to repair of structural cracks and large gouges. If damage is
cosmetic, use of reinforcing cloth may not be necessary.
1. Panels to be repaired should be dry and at room temperature 18°C (65°F) to 24°C (75°F) prior to
carrying out any repairs. Both sides of the panel must be thoroughly cleaned before sanding or
grinding.
2. Cover the break in the SMC (front and back) with masking tape. This protects the damaged area
from absorbing the prep cleaner and eliminates wicking of the cleaner through the fibers into the
SMC .
3. Remove all waxes, silicones, dirt and road oils from the area surrounding both sides of the
damaged area with a plastics wax and grease remover.
Remove the tape and sand the back of the repair area with an angle grinder, Dual Action
(D/A) sander or by hand using 80-grit sandpaper. Remove all dust with a vacuum and tack
cloth.
4. Create a reinforcing patch using a piece of scrap SMC that conforms well to the back of the
damaged area or form a patch from fiberglass cloth.
Cut a section of cloth large enough to cover the repair, plus 25.4 mm (1 in) around the
repair area.
Cut a section of plastic film backing approximately 25.4 mm (1 in) larger than the cloth. Lay
the plastic on a smooth, flat surface where it will be used to create a pyramid patch.
5. Follow manufacturer's directions and apply plastic repair adhesive to the plastic film backing and
smooth with plastic spreader to recommended thickness. Place the pre-cut fiberglass cloth on the
adhesive-coated plastic film. Cover the cloth with a coat of repair adhesive and spread to the
recommended thickness.
6. Apply the prepared patch to the backside of the panel and compress. Follow manufacturer's
instructions for adhesive cure. Remove plastic film after adhesive cures and sand as necessary to
remove roughness.
7. Remove masking tape from the front side of damaged area and grind down to the backing patch.
Use an angle grinder with a 30- to 40-grit wheel. Make a gradual taper in the area, this will
prevent bull's-eyes or read-through in the finished repair. Sand prepared area with a D/A sander
or hand-sand with 80-grit sandpaper.
8. Build a pyramid patch using fiberglass cloth or equivalent and plastic repair adhesive. Following
manufacturer's directions, apply patch to damaged area.
9. Rough-grind area to remove excess adhesive. Sand repair area with 80-grit sandpaper, making
sure to cut slightly below the SMC finished surface. This will allow for a finish coat of plastic body
repair material.
10. Apply a finish coat of plastic repair filler material per manufacturer's directions.
11. Finish-sand, prime and topcoat using Ford-approved paint systems.
Thermoplastic Compounds
1. In deciding whether to repair or install a new component, follow these guidelines.
Is a part readily available?
Can the damaged part be economically returned to its original strength and appearance, or
will the labor cost exceed the cost of a new component?
Will repair provide for the fastest, highest quality repair?
2. NOTE: The following steps are to be used as a guideline. Depending on what brand of adhesives
or patch materials are used, procedures may vary slightly.
Thoroughly clean the damaged area with wax and grease remover formulated for use with
plastics.
3. Hand sand the repair area with 80-grit sandpaper and remove any foreign material with
compressed air.
4. Apply a plastics adhesion promoter per label directions to the repair area.
5. For small repairs, a plastic adhesive filler can be applied to the damaged area. Follow
manufacturer's directions and build layers to form a thickness above the damaged area. This will
allow the area to be sanded smooth.
6. To repair large holes or cracks, measure and cut a piece of fiberglass cloth or equivalent 25.4 mm
(1 in) larger than the crack or hole.
Apply plastic repair adhesive to the damaged area and immediately apply fiberglass cloth
into plastic adhesive for reinforcement. Apply additional plastic repair adhesive for strength
and shape as required.
7. Contour and shape the repair as necessary with a D/A sander. Avoid sanding through the repair.
8. Finish-sand the area and carry out any required paint operations using Ford-approved paint
systems.
Tab Repair — Bumper
1. NOTE: Inspect the bumper cover to determine if part of it can be repaired to an acceptable level
of quality of appearance, fit and durability. Will labor and material cost of the repair meet or
exceed the cost of a new replacement bumper cover? If the bumper cover is determined to be
repairable, proceed to the following steps.
NOTE: The following steps are to be used as a guideline. Depending on what brand of adhesives
or patch materials are used, procedures may vary slightly.
Remove the affected bumper. For additional information, refer to Section 501-19 .
NOTE: Illustration is not vehicle specific.
2. Clean the broken tab(s) with a plastics wax and grease remover.
3. Hand sand the repair area with 80-grit sandpaper and remove any foreign material with
compressed air.
4. Apply a plastics adhesion promoter per label directions to the repair area.
5. Measure and cut a patch of fiberglass cloth or equivalent large enough to form the front of the tab,
then slope back in a wedge shape approximately 51 mm (2 in) from original tab.
6. Prepare the repair adhesive cloth patch per manufacturer's instructions and apply to the affected
area.
Immediately position the plastic repair material patch to form the tab shape.
7. Allow appropriate cure time and shape the repair tab using a small angle sander. Use extreme
care to not sand through the exterior surface.
8. Carry out any required paint repair operations to the bumper cover using Ford-approved paint
systems.

WARNING: Never install used or reconditioned parts (as specified below) from pre-owned,
salvaged or damaged vehicles. The use of such parts could lead to serious injury.
Never use non-Ford parts or accessories for completing repairs.
Ford Motor Company does not approve or recognize body and structural repair procedures, tools, parts
or anything but new genuine Ford equipment. Ford cannot attest to the safety, quality, durability or
legality of non-Ford parts or accessories. Use of such parts could lead to serious personal injury as
they may contain damage which is not visible.
Ford does not approve use of the following:
Salvaged or used parts
Major body clips or assemblies from salvage vehicles
Aftermarket structural or body components
Salvaged or reconditioned wheels
Used supplemental restraint system (SRS) components
air bags
restraint system modules
safety belts, buckles or retractors
crash sensors
Returning a vehicle to pre-accident condition can only be assured if repair procedures are carried out
by skilled technicians using new genuine Ford parts and Ford-approved methods. Structural
component repair procedures approved by Ford, using genuine Ford parts, have been validated by
Ford Motor Company engineers.
Ford Motor Company does not endorse, cannot attest to, and makes no representations regarding
structural repairs (frames, rails, aprons and body panels) carried out using non-genuine Ford Motor
Company parts or non-Ford-approved methods. In particular, Ford makes no representations that the
vehicle will meet any crash safety or anti-corrosion performance requirement. Such parts and methods
have not been tested by Ford, and may not meet Ford's requirements for safety, performance, strength,
quality, durability and corrosion protection.
Ford Motor Company bears no responsibility or liability of any kind if repairs are performed using
alternative structural component repair procedures and/or parts.
WARNING: Invisible ultraviolet and infrared rays emitted in welding can injure unprotected eyes
and skin. Always use protection such as a welder's helmet with dark-colored filter lenses of the correct
density. Electric welding will produce intense radiation, therefore, filter plate lenses of the deepest
shade providing adequate visibility are recommended. It is strongly recommended that persons
working in the weld area wear flash safety goggles. Also wear protective clothing. Failure to follow
these instructions may result in serious personal injury.
WARNING: Do not cut or grind body side components within 50 mm (1.96 in) of restraint
anchoring points. Welding within 50 mm (1.96 in) of restraint anchoring points may result in incorrect
operation of restraint devices. For additional restraints anchoring location information, refer to Section
501-20A and Section 501-20B . Failure to follow these instructions may result in serious injury to
vehicle occupant(s).
WARNING: Do not carry out body side sectioning repairs in areas of laser welds. Factory laser
welds cannot be duplicated with conventional welding equipment and structural integrity may be
compromised. Failure to follow this instruction may result in serious injury to vehicle occupant(s).
WARNING: Do not carry out body side sectioning repairs in areas of door hinge or striker
anchoring points. Welding within 50 mm (1.96 in) of door hinge or striker locations may compromise
structural integrity during a collision. Failure to follow these instructions may result in serious injury to
vehicle occupant(s).
WARNING: On vehicles equipped with Safety Canopy® options, prior to carrying out any
sectioning repairs near the roof line or sail panel areas of the vehicle, remove the Safety Canopy®
module and related components. Failure to comply may result in accidental deployment or damage to
the Safety Canopy®. Refer to Section 501-20B . Failure to follow these instructions may result in
serious injury to technician or vehicle occupant(s).
NOTE: Factory spot welds may be substituted with either resistance spot welds or Metal Inert Gas (MIG) plug
welds. Spot/plug welds should equal factory welds in both location and quantity. Do not place a new spot weld
directly over an original weld location. Plug weld hole should equal 8 mm (0.31 in) diameter.
1. Remove the outer body sheet metal from the affected area prior to carrying out any reinforcing panel
replacement. For additional information, refer to Sectioning Guidelines in this section.
2. NOTE: Observe prescribed welding procedures when carrying out repairs. For additional information,
refer to Welding Precautions — Steel in this section.
NOTE: When it is necessary to carry out weld-bonding procedures, refer to Weld-Bonding in this section.
Remove the outer body sheet metal from the affected area prior to carrying out any reinforcing panel
replacement. For additional information, refer to Sectioning Guidelines in this section.
3. When welding overlapping surfaces or substrates, apply a high quality weld-through primer between the
surfaces prior to welding.
Make sure horizontal joints and flanges are correctly sealed with seam sealer to prevent moisture
intrusion. Water and moisture migrate to horizontal joints and corrosion tends to occur more
rapidly in these areas. Clean metal surfaces with metal surface prep or equivalent applying seam
sealer.
4. Proceed with refinish procedures following Ford-approved paint guidelines.
5. Apply corrosion protection as necessary to repair area.

There are 2 diagnostic paths that can be followed depending on the type of engine concern. Carry out
either Inspection and Verification — Engine Performance or Inspection and Verification — NVH.
Inspection and Verification — Engine Performance
1. Verify the customer concern by operating the engine to duplicate the condition.
2. Visually inspect for obvious signs of mechanical damage. Refer to the following chart.
Visual Inspection Chart
Mechanical
Engine coolant leaks
Engine oil leaks
Fuel leaks
Damaged or severely worn parts
Loose mounting bolts, studs and nuts
3. If the inspection reveals obvious concerns that can be readily identified, repair as necessary.
4. NOTE: Make sure to use the latest scan tool software release.
If the cause is not visually evident, connect the scan tool to the Data Link Connector (DLC).
5. NOTE: The Vehicle Communication Module (VCM) LED prove out confirms power and ground
from the DLC are provided to the VCM .
If the scan tool does not communicate with the VCM :
check the VCM connection to the vehicle.
check the scan tool connection to the VCM .
refer to Section 418-00 , No Power To The Scan Tool, to diagnose no power to the scan
tool.
6. If the scan tool does not communicate with the vehicle:
verify the ignition key is in the ON position.
verify the scan tool operation with a known good vehicle.
refer to Section 418-00 to diagnose no response from the PCM.
7. Carry out the network test.
If the scan tool responds with no communication for one or more modules, refer to Section
418-00 .
If the network test passes, retrieve and record Continuous Memory Diagnostic Trouble
Codes (CMDTCs).
8. Clear the continuous DTCs and carry out the self-test diagnostics for the PCM.
9. If the DTCs retrieved are related to the concern, go to the DTC Chart, refer to Section 419-10 .
10. If no DTCs related to the concern are retrieved, GO to Symptom Chart - Engine .
Inspection and Verification — NVH
1. NVH symptoms should be identified using the diagnostic tools and techniques that are available.
For a list of these techniques, tools, an explanation of their uses and a glossary of common
terms, refer to Section 100-04 .
2. Verify the customer concern by operating the engine to duplicate the condition.
3. Check the engine oil level and check the oil for contamination. Low engine oil level or
contaminated oil are a common cause of engine noise. If the oil is contaminated, the source of
the contamination must be identified and repaired as necessary.
4. Visually inspect for obvious signs of mechanical damage. Refer to the following chart.
Visual Inspection Chart
Mechanical
Loose mounting bolts, studs and nuts
Damaged or leaking powertrain mounts
Damaged or disconnected vacuum hoses
Obstruction of cooling fan
Obstruction of Front End Accessory Drive (FEAD)

verify the scan tool operation with a known good vehicle.
refer to Section 418-00 to diagnose no response from the PCM.
9. Carry out the network test.
If the scan tool responds with no communication for one or more modules, refer to Section
418-00 .
If the network test passes, retrieve and record continuous memory DTCs.
10. Clear the continuous DTCs and carry out the self-test diagnostics for the PCM.
11. If the DTCs retrieved are related to the concern, go to the DTC Chart, refer to Section 419-10 .
12. If no DTCs related to the concern are retrieved, continue the inspection and verification if a noise
concern is related to the engine. For vibration concerns and noise concerns such as powertrain
mounts, air intake system and starter, GO to Symptom Chart - NVH .
In some cases, a noise may be a normal characteristic of that engine type. In other cases the noise may
require further investigation. Comparing the noise to a similar year/model vehicle equipped with the
same engine will aid in determining if the noise is normal or abnormal.
Once a customer concern has been identified as an abnormal engine noise, it is critical to determine the
location of the specific noise. Use the EngineEAR/ChassisEAR or stethoscope (the noise will always be
louder closer to the noise source) to isolate the location of the noise to one of the following:
Fuel injector(s)
Upper end of engine
Lower end of engine
Front of engine
Rear of engine
Fuel injector noise
A common source of an engine ticking noise can be related to the fuel injector(s). This is normal engine
noise that can be verified by listening to another vehicle. If the injector noise is excessive or irregular,
use the EngineEAR/ChassisEAR or stethoscope to isolate the noise to a specific fuel injector.
Upper end engine noise
A common source of upper end engine noise (ticking, knocking or rattle) include the camshaft(s) and
valve train. Upper end engine noise can be determined using the EngineEAR/ChassisEAR or
stethoscope on the valve cover bolts. If the noise is loudest from the valve cover bolts, then the noise is
upper end. The EngineEAR/ChassisEAR or stethoscope can be used to further isolate the noise to the
specific cylinder bank and cylinder. Removal of the valve covers will be required to visually inspect the
valve train to pinpoint the source of the noise.
Lower end engine noise
A common source of lower end engine noise (ticking or knocking) include the crankshaft, connecting rod
(s) and bearings. Lower end noises can be determined by using the oil pan or lower cylinder block. If the
noise is loudest from these areas, then the noise is lower end. If an engine noise is isolated to the lower
end, some disassembly of the engine may be required to inspect for damage or wear.
Front of engine noise
A common source of noise from the front of the engine (squeal, chirp, whine or hoot) is the Front End
Accessory Drive (FEAD) components. To isolate FEAD noise, carry out the Engine Accessory Test,
refer to Section 100-04 .
Some other noises from the front of the engine (ticking, tapping or rattle) may be internal to the engine.
Use the EngineEAR/ChassisEAR or stethoscope on the engine front cover to determine if the noise is
internal to the engine. Removal of the engine front cover may be necessary to inspect internal engine
components.
Rear of engine noise
A common source of noise from the rear of the engine (knocking) is the flywheel/flexplate. Inspection of
the flywheel/flexplate will be necessary.
If equipped, the Rear End Accessory Drive (READ) can also be a source of noise from the rear of the
engine (squeal or chirp). The READ consists of the coolant pump and belt.
Some engines have timing drive components at the rear of the engine and may be the source of noise
(ticking, knocking or rattle). Use the EngineEAR/ChassisEAR or stethoscope on the rear of the engine if
the noise is suspected to be internal to the engine. Some disassembly of the engine may be required to
inspect for damage or wear.
13. After the noise is localized, note the characteristics of the noise, including type of noise,
frequency and conditions when the noise occurs and GO to Symptom Chart - NVH .

Component Tests
The following component tests are used to diagnose engine concerns.
Engine Oil Leaks
NOTE: When diagnosing engine oil leaks, the source and location of the leak must be positively
identified prior to repair. If the vehicle is driven extensively between adding the fluorescent additive and
performing the leak test, fan air or wind can spread the leaking oil and make identifying the location of
the leak difficult.
Prior to carrying out this procedure, clean the cylinder block, cylinder heads, valve covers, oil pan and
flywheel with a suitable solvent to remove all traces of oil.
Engine Oil Leaks — Fluorescent Oil Additive Method
Use the 12 Volt Master UV Diagnostic Inspection Kit to carry out the following procedure for oil leak
diagnosis.
1. Add 29.6 ml (1 oz) of gasoline engine oil dye to a minimum of 0.47L (1/2 qt) and a maximum of
0.95L (1 qt) engine oil and fill through the engine oil fill. Thoroughly premix the gasoline engine oil
dye or it will not have enough time to reach the crankcase, oil galleries and seal surfaces during
this particular 15 minute test. The additive must be mixed well with oil and added through the oil
fill. Check the level on the oil level indicator to determine what amount of oil to premix. If it is in
the middle of the crosshatch area or below the full mark, use 0.95L (1 qt). If it is at the full mark,
use 0.47L (1/2 qt).
2. Run the engine for 15 minutes. Stop the engine and inspect all seal and gasket areas for leaks
using the UV Leak Detector Kit. A clear bright yellow or orange area will identify the leak. For
extremely small leaks, several hours may be required for the leak to appear.
3. At the end of test, make sure the oil level is within the upper and lower oil indicator marks.
Remove oil as necessary if it registers above the full mark.
Leakage Points — Underhood
Examine the following areas for oil leakage:
Valve cover gaskets
Cylinder head gaskets
Oil cooler, if equipped
Oil filter adapter
Engine front cover
Oil filter adapter and filter body
Oil level indicator tube connection
Engine Oil Pressure (EOP) switch
Leakage Points — Under Engine, With Vehicle on Hoist
Examine the following areas for oil leakage:
Oil pan gaskets
Oil pan sealer
Engine front cover gasket
Crankshaft front seal
Crankshaft rear oil seal
Oil filter adapter and filter body
Oil cooler, if equipped
Leakage Points — With Transmission and Flywheel Removed
Examine the following areas for oil leakage:
Crankshaft rear oil seal
Rear main bearing cap parting line
Flexplate mounting bolt holes (with flexplate installed)
Pipe plugs at the end of oil passages
Oil leaks at crimped seams in sheet metal parts and cracks in cast or stamped parts can be detected
when using the dye method.
Compression Test
1. Make sure the oil in the crankcase is of the correct viscosity and at the correct level and that the
battery is correctly charged. Operate the vehicle until the engine is at normal operating
temperature. Turn the ignition switch to the OFF position, then remove all the spark plugs.
2. Set the throttle plates in the wide-open position.
3. Install a compression gauge in the No. 1 cylinder.
4. Install an auxiliary starter switch in the starting circuit. With the ignition switch in the OFF position,
and using the auxiliary starter switch, crank the engine a minimum of 5 compression strokes and
record the highest reading. Note the approximate number of compression strokes necessary to
obtain the highest reading.
5. Repeat the test on each cylinder, cranking the engine approximately the same number of
compression strokes.
Compression Test — Test Results
The indicated compression pressures are considered within specification if the lowest reading cylinder is
at least 75% of the highest reading. Refer to the Compression Pressure Limit Chart.

If one or more cylinders reads low, squirt approximately one tablespoon of engine oil meeting Ford
specification on top of the pistons in the low-reading cylinders. Repeat the compression pressure check
on these cylinders.
Compression Test — Interpreting Compression Readings
1. If compression improves considerably, piston rings are worn or damaged.
2. If compression does not improve, valves are sticking or not seating correctly.
3. If 2 adjacent cylinders indicate low compression pressures and squirting oil on each piston does
not increase compression, the head gasket may be leaking between cylinders. Engine oil or
coolant in cylinders could result from this condition.
Use the Compression Pressure Limit Chart when checking cylinder compression so that the
lowest reading is within 75% of the highest reading.
Cylinder Leakage Detection
When a cylinder produces a low reading, use of a cylinder leakage tester will be helpful in pinpointing
the exact cause.
The leakage tester is inserted in the spark plug hole, the piston is brought up to Top Dead Center (TDC)
on the compression stroke, and compressed air is admitted.
Once the combustion chamber is pressurized, the leakage tester gauge will read the percentage of
leakage. Leakage exceeding 20% is excessive.
While the air pressure is retained in the cylinder, listen for the hiss of escaping air. A leak at the intake
valve will be heard in the Throttle Body (TB). A leak at the exhaust valve can be heard at the tailpipe.
Leakage past the piston rings will be audible at the PCV connection. If air is passing through a blown
head gasket to an adjacent cylinder, the noise will be evident at the spark plug hole of the cylinder into
which the air is leaking. Cracks in the cylinder block or gasket leakage into the cooling system may be
detected by a stream of bubbles in the radiator.
Excessive Engine Oil Consumption
Nearly all engines consume oil, which is essential for normal lubrication of the cylinder bore walls and
pistons and rings. Determining the level of oil consumption may require testing by recording how much
oil is being added over a given set of miles.
Customer driving habits greatly influence oil consumption. Mileage accumulated during towing or heavy
loading generates extra heat. Frequent short trips, stop-and-go type traffic or extensive idling, prevent
the engine from reaching normal operating temperature. This prevents component clearances from
reaching specified operating ranges.
The following diagnostic procedure may be utilized to determine internal oil consumption. Make sure that
the concern is related to internal oil consumption, and not external leakage, which also consumes oil.
Verify there are no leaks before carrying out the test. Once verified, the rate of internal oil consumption
can be tested.
A new engine may require extra oil in the early stages of operation. Internal piston-to-bore clearances
and sealing characteristics improve as the engine breaks in. Engines are designed for close tolerances
and do not require break-in oils or additives. Use the oil specified in the Owner's Literature. Ambient
temperatures may determine the oil viscosity specification. Verify that the correct oil is being used for the
vehicle in the geographic region in which it is driven.
Basic Pre-checks
1. For persistent complaints of oil consumption, interview the customer to determine the oil
consumption characteristics. If possible, determine the brand and grade of oil currently in the oil
pan. Look at the oil filter or oil-change station tags to determine if Ford-recommended
maintenance schedules have been followed. Make sure that the oil has been changed at the
specified mileage intervals. If vehicle mileage is past the first recommended drain interval, the
OEM production filter should have been changed.
2. Ask how the most current mileage was accumulated. That is, determine whether the vehicle was
driven under the following conditions:
Extended idling or curbside engine operation
Stop-and-go traffic or taxi operation
Towing a trailer or vehicle loaded heavily
Frequent short trips (engine not up to normal operating temperature)
Excessive throttling or high engine-rpm driving
3. Verify that there are no external leaks. If necessary, review the diagnostic procedure under
Engine Oil Leaks in the Diagnosis and Testing portion of this section.
4. Inspect the crankcase ventilation system for:
disconnected hoses at the valve cover or TB .
loose or missing valve cover fill cap.
missing or incorrectly seated engine oil level indicator.
incorrect or dirty PCV valve.
a PCV valve grommet unseated in the valve cover (if so equipped).
5. Inspect for signs of sludge. Sludge affects PCV performance and can plug or restrict cylinder
head drainback wells. It can also increase oil pressure by restricting passages and reducing the
drainback capability of piston oil control rings. Sludge can result from either excessive water
ingestion in the crankcase or operation at extremely high crankcase temperatures.
6. Inspect the air filter for dirt, sludge or damage. A hole in the filter element will allow unfiltered air
to bypass into the air induction system. This can cause premature internal wear (engine dusting),
allowing oil to escape past rings, pistons, valves and guides.
7. If the engine is hot or was recently shut down, wait at least 5 minutes to allow the oil to drain
back. Ask the customer if this requirement has been followed. Adding oil without this wait period
can cause an overfill condition, leading to excessive oil consumption and foaming which may
cause engine damage.
8. Make sure the oil level indicator (dipstick) is correctly and fully seated in the indicator tube.
Remove the oil level indicator and record the oil level.
Detailed Pre-checks
1. Check the thermostat opening temperature to make sure that the cooling system is operating at
the specified temperature. If it is low, internal engine parts are not running at specified internal
operating clearances.
2. Verify the spark plugs are not oil saturated. Oil leaking into one or more cylinders will appear as
an oil soaked condition on the plug. If a plug is saturated, a compression check may be
necessary at the conclusion of the oil consumption test.
Oil Consumption Test
Once all of the previous conditions are met, carry out an oil consumption test.
1. Drain the engine oil and remove the oil filter. Install a new manufacturer-specified oil filter. Make
sure the vehicle is positioned on a level surface. Refill the oil pan to a level one liter (quart) less
than the specified fill level, using manufacturer-specified oil.
2. Run the engine for 3 minutes (if hot) or 10 minutes (if cold). Allow for a minimum 5-minute
drainback period and then record the oil level shown on the oil level indicator. Place a mark on
the backside of the oil level indicator noting the oil level location.
3. Add the final one liter (quart) to complete the normal oil fill. Restart the engine and allow it to idle
for 2 minutes. Shut the engine down.
4. After a 5-minute drainback period, record the location of the oil level again. Mark the oil level
indicator with the new oil level location. (Note: Both marks should be very close to the MIN-MAX
upper and lower limits or the upper and lower holes on the oil level indicator. These marks will
exactly measure the engine's use of oil, with a one quart differential between the new marks.)
Demonstrate to the customer that the factory-calibrated marks on the oil level indicator are where
the oil should fall after an oil change with the specified fill amount. Explain however, that this may
vary slightly between MIN-MAX or the upper and lower holes on the oil level indicator.
5. Record the vehicle mileage.
6. Advise the customer that oil level indicator readings must be taken every 320 km (200 mi) or
weekly, using the revised marks as drawn. Remind the customer that the engine needs a
minimum 5-minute drainback for an accurate reading and that the oil level indicator must be firmly
seated in the tube prior to taking the reading.
7. When the subsequent indicator readings demonstrate a full liter (quart) has been used, record the
vehicle mileage. The mileage driven should not be less than 2,414 km (1,500 mi). The drive cycle
the vehicle has been operated under must be considered when making this calculation. It may be
necessary to have the customer bring the vehicle in for a periodic oil level indicator reading to
closely monitor oil usage.
Post Checks, Evaluation and Corrective Action
1. If test results indicate excessive oil consumption, carry out a cylinder compression test. The
cylinder compression test should be carried out with a fully charged battery and all spark plugs
removed. See the Compression Test Chart in this section for pressure range limits.
2. Compression should be consistent across all cylinders. Refer to the Compression Testing portion
of this section. If compression tested within the specifications found in this section, the excessive
oil consumption may be due to wear on the valve guides, valves or valve seals.
3. A cylinder leak detection test can be carried out using a cylinder leakage tester. This can help
identify valves, piston rings, or worn valve guides/valve stems, inoperative valve stem seals or
other related areas as the source of oil consumption.
NOTE: An oil-soaked appearance on the porcelain tips of the spark plugs also indicates excessive oil
use. A typical engine with normal oil consumption will exhibit a light tan to brown appearance. See Spark
Plug Analysis in this section for details. A single or adjoining, multiple cylinder leak can be traced by
viewing the tips.
4. If an internal engine part is isolated as the root cause, determine if the repair will exceed cost
limits and proceed with a repair strategy as required.
5. Once corrective action to engine is complete and verifying that all pre-check items were
eliminated in the original diagnosis, repeat the Oil Consumption Test as described above and
verify consumption results.
Intake Manifold Vacuum Test
Bring the engine to normal operating temperature. Connect the Vacuum/Pressure Tester to the intake
manifold. Run the engine at the specified idle speed.
The vacuum gauge should read between 51-74 kPa (15-22 in-Hg) depending upon the engine condition
and the altitude at which the test is conducted. Subtract 4.0193 kPa (1 in-Hg) from the specified reading
for every 304.8 m (1,000 ft) of elevation above sea level.
The reading should be steady. If necessary, adjust the gauge damper control (where used) if the needle
is fluttering rapidly. Adjust the damper until the needle moves easily without excessive flutter.
Intake Manifold Vacuum Test — Interpreting Vacuum Gauge Readings
A careful study of the vacuum gauge reading while the engine is idling will help pinpoint trouble areas.
Always conduct other appropriate tests before arriving at a final diagnostic decision. Vacuum gauge
readings, although helpful, must be interpreted carefully.
Most vacuum gauges have a normal band indicated on the gauge face.
The following are potential gauge readings. Some are normal; others should be investigated further.
1. NORMAL READING: Needle between 51-74 kPa (15-22 in-Hg) and holding steady.
2. NORMAL READING DURING RAPID ACCELERATION AND DECELERATION: When the engine
is rapidly accelerated (dotted needle), the needle will drop to a low reading (not to zero). When
the throttle is suddenly released, the needle will snap back up to a higher than normal figure.
3. NORMAL FOR HIGH-LIFT CAMSHAFT WITH LARGE OVERLAP: The needle will register as low
as 51 kPa (15 in-Hg) but will be relatively steady. Some oscillation is normal.
4. WORN RINGS OR DILUTED OIL: When the engine is accelerated (dotted needle), the needle
drops to 0 kPa (0 in-Hg). Upon deceleration, the needle runs slightly above 74 kPa (22 in-Hg).
5. STICKING VALVES: When the needle (dotted) remains steady at a normal vacuum but
occasionally flicks (sharp, fast movement) down and back about 13 kPa (4 in-Hg), one or more
valves may be sticking.
6. BURNED OR WARPED VALVES: A regular, evenly-spaced, downscale flicking of the needle
indicates one or more burned or warped valves. Insufficient valve clearance will also cause this
reaction.
7. POOR VALVE SEATING: A small but regular downscale flicking can mean one or more valves
are not seating.
8. WORN VALVE GUIDES: When the needle oscillates over about a 13 kPa (4 in-Hg) range at idle
speed, the valve guides could be worn. As engine speed increases, the needle will become
steady if guides are responsible.
9. WEAK VALVE SPRINGS: When the needle oscillation becomes more violent as engine rpm is
increased, weak valve springs are indicated. The reading at idle could be relatively steady.
10. LATE VALVE TIMING: A steady but low reading could be caused by late valve timing.
11. IGNITION TIMING RETARDING: Retarded ignition timing will produce a steady but somewhat
low reading.
12. INSUFFICIENT SPARK PLUG GAP: When spark plugs are gapped too close, a regular, small
pulsation of the needle can occur.
13. INTAKE LEAK: A low, steady reading can be caused by an intake manifold or throttle body gasket
leak.
14. BLOWN HEAD GASKET: A regular drop of fair magnitude can be caused by a blown head gasket
or warped cylinder head-to-cylinder block surface.
15. RESTRICTED EXHAUST SYSTEM: When the engine is first started and is idled, the reading may
be normal, but as the engine rpm is increased, the back pressure caused by a clogged muffler,
kinked tailpipe or other concerns will cause the needle to slowly drop to 0 kPa (0 in-Hg). The
needle then may slowly rise. Excessive exhaust clogging will cause the needle to drop to a low
point even if the engine is only idling.
16. When vacuum leaks are indicated, search out and correct the cause. Excess air leaking into the
system will upset the fuel mixture and cause concerns such as rough idle, missing on
acceleration or burned valves. If the leak exists in an accessory unit such as the power brake
booster, the unit will not function correctly. Always fix vacuum leaks.
Oil Pressure Test
1. Disconnect and remove the Engine Oil Pressure (EOP) switch from the engine.
2. Connect the Oil Pressure Gauge to the oil pressure switch oil galley port.
3. Run the engine until normal operating temperature is reached.
4. Run the engine at the specified rpm and record the gauge reading.
5. The oil pressure should be within specifications; refer to the specification chart in the appropriate
engine section.
6. If the pressure is not within specification, check the following possible sources:
Insufficient oil
Oil leakage
Worn or damaged oil pump
Oil pump screen cover and tube
Excessive main bearing clearance
Excessive connecting rod bearing clearance
Chain tensioner leak

Spark Plug Inspection
1. Inspect the spark plug for a bridged gap.
Check for deposit build-up closing the gap between the electrodes. Deposits are caused by
oil or carbon fouling.
Install a new spark plug.
2. Check for oil fouling.
Check for wet, black deposits on the insulator shell bore electrodes, caused by excessive
oil entering the combustion chamber through worn rings and pistons, excessive valve-toguide clearance or worn or loose bearings.
Correct the oil leak concern.
Install a new spark plug.
3. Inspect for carbon fouling. Look for black, dry, fluffy carbon deposits on the insulator tips, exposed
shell surfaces and electrodes, caused by a spark plug with an incorrect heat range, dirty air
cleaner, too rich a fuel mixture or excessive idling.
Install new spark plugs.
4. Inspect for normal burning.
Check for light tan or gray deposits on the firing tip.
5. Inspect for pre-ignition, identified by melted electrodes and a possibly damaged insulator. Metallic
deposits on the insulator indicate engine damage. This may be caused by incorrect ignition
timing, wrong type of fuel or the unauthorized installation of a heli-coil insert in place of the spark
plug threads.
Install a new spark plug.
6. Inspect for overheating, identified by white or light gray spots and a bluish-burnt appearance of
electrodes. This is caused by engine overheating, wrong type of fuel, loose spark plugs, spark
plugs with an incorrect heat range, low fuel pump pressure or incorrect ignition timing.
Install a new spark plug.
7. Inspect for fused deposits, identified by melted or spotty deposits resembling bubbles or blisters.
These are caused by sudden acceleration.
Install new spark plugs.

SECTION 303-01: Engine — 1.6L
DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 04/19/2011
Engine
The 1.6L 4-cylinder engine has the following features:
Dual overhead camshaft
Four valves per cylinder
Sequential Multi-Port Fuel Injection (SFI)
Aluminum cylinder head
Aluminum cylinder block
Twin independent Variable Camshaft Timing (VCT) system
The 1.6L engine is a 4 valve-per-cylinder, dual overhead camshaft engine. The engine uses an ignition
coil and spark plug wires. The cylinder block is made of aluminum and the bearing caps are integrated
into the ladder assembly. An aluminum oil pan bolts to the bottom of the lower cylinder block and to the
transmission to provide greater strength. The camshafts are mounted in the cylinder head and act
against valve tappets to open and close the valves. The camshafts are driven off the front of the cylinder
head by one timing belt. The belt is driven by a sprocket that is located on the crankshaft. The piston
assembly is an aluminum piston with a sinter forged carbon steel connecting rod. The oil pump is driven
by the crankshaft.
Engine Identification
Always refer to these labels when installation of new parts is necessary or when checking engine
calibrations. The engine parts often differ within a CID family. Verification of the identification codes will
make sure the correct parts are obtained. These codes contain all the pertinent information relating to
the dates, optional equipment and revisions.
Engine Code Information Label
The engine code information label, located on the front side of the timing cover, contains the following:

Engine Cylinder Identification
Exhaust Emission Control System
Operation and necessary maintenance of the exhaust emission control devices used on this engine are
covered in the Powertrain Control/Emissions Diagnosis (PC/ED) manual.
Induction System
The SFI provides the fuel/air mixture needed for combustion in the cylinders. The 4 solenoid-operated
fuel injectors:
are mounted in the cylinder head.
meter fuel into the air intake stream in accordance with engine demand.
are positioned so that their tips direct fuel just ahead of the engine intake valves.
supply fuel from the fuel tank with a fuel pump mounted in the fuel tank.
Twin Independent Variable Camshaft Timing (VCT) System
The twin independent VCT system allows variable control of intake valve closing which optimizes
combustion at full load providing improved power and low speed torque (broadening the torque curve)
which enables variable valve overlap which provides better fuel economy and emissions and provides
optimized cold start operation with improved exhaust emissions.
PCV System
All engines are equipped with a closed-type PCV system recycling the crankcase vapors to the intake
manifold.
Lubrication System
The engine lubrication system operates as follows:
Oil is drawn into the oil pump through the oil pump screen cover and tube in the sump of the oil
pan.
Oil is pumped through the oil filter on the left front side of the cylinder block and is cooled by an oil
cooler.
Oil enters the main gallery where it is distributed to the crankshaft main journals and to the
cylinder head.
From the main journals, the oil is routed through cross-drilled passages in the crankshaft to
lubricate the connecting rod bearings. Controlled leakage through the crankshaft main bearings
and connecting rod bearings is slung radially outward to cool and lubricate the cylinder walls as
well as the entire connecting rod, piston and piston ring assembly.

Engine
Refer to Section 303-00 for basic mechanical concerns or refer to the Powertrain Control/Emissions
Diagnosis (PC/ED) manual for driveability concerns.
SECTION 303-01: Engine — 1.6L
GENERAL PROCEDURES
2011 Fiesta Workshop Manual
Procedure revision date: 11/11/2010
Valve Clearance Check
1. Remove the valve cover. For additional information, refer to Valve Cover in this section.
2. Remove the 4 spark plugs. For additional information, refer to Section 303-07 .
3. Remove the 2 bolts and accessory drive belt splash shield.
To install, tighten to 9 Nm (80 lb-in).
4. NOTE: Turn the engine clockwise only, and use the crankshaft bolt only.
NOTE: Measure each valve's clearance at base circle, with the lobe pointed away from the
tappet, before removing the camshafts. Failure to measure all clearances prior to removing the
camshafts will necessitate repeated removal and installation and wasted labor time.
Use a feeler gauge to measure each valve's clearance and record its location.
5. NOTE: The number on the valve tappet only reflects the digits that follow the decimal. For
example, a tappet with the number 0.650 has the thickness of 3.650 mm.
NOTE: The nominal clearance is 0.20 mm (0.0079 in) for intake and 0.34 mm (0.0133 in) for
exhaust.
NOTE: The acceptable clearances after being fully installed is 0.17-0.23 mm (0.007-0.009 in) for
intake and 0.31-0.37 mm (0.012-0.015 in) for exhaust.
Select tappets using this formula: tappet thickness = measured clearance + the existing tappet
thickness - nominal clearance.
Select the closest tappet size to the ideal tappet thickness available and mark the installation
location.
6. If any tappets do not measure within specifications, install new tappets in these locations. For
additional information, refer to Valve Train Components — Exploded View and Valve Tappets in
this section.

DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 10/19/2010
Engine Cooling
NOTICE: The engine cooling system is filled with Motorcraft® Specialty Orange Engine Coolant.
Do not mix coolant types. Mixing coolant types degrades the corrosion protection of Motorcraft®
Specialty Orange Engine Coolant. Failure to follow these instructions may damage the engine or
cooling system.
NOTE: During normal vehicle operation, Motorcraft Specialty Orange Engine Coolant may change color
from orange to pink or light red. As long as the engine coolant is clear and uncontaminated, this color
change does not indicate the engine coolant has degraded nor does it require the engine coolant to be
drained, the system to be flushed, or the engine coolant to be replaced.
The cooling system components include the:
radiator
cooling fan motor and shroud
degas bottle
radiator drain valve
coolant pump
thermostat housing
block heater (if equipped)
The engine uses a cold side thermostat. This means the thermostat is located at the lower radiator hose
connection to the engine, where coolant enters the engine after being cooled by the radiator. During
initial warm-up, the cooler coolant from the radiator quickly closes the thermostat after the warm coolant
in the engine opens the thermostat slightly. The thermostat opens and closes several times before the
coolant coming from the radiator is warm enough to allow the thermostat to remain open. The engine
must run much longer than a vehicle with a hot side thermostat before the thermostat remains fully
opened.
Engine coolant provides freeze protection, boil protection, corrosion protection and cooling efficiency to
the engine and cooling components. In order to obtain these protections, maintain the engine coolant at
the correct concentration and fluid level in the degas bottle.
When adding engine coolant, use a 50/50 mixture of engine coolant and distilled water. A coolant
concentration of 50% will provide freeze point protection down to -37°C (-34°F).
To maintain the integrity of the coolant and the cooling system:
Add Motorcraft® Specialty Orange Engine Coolant or equivalent meeting Ford specification WSSM97B44-D (orange color).
Do not add or mix with any other engine coolant. Mixing coolants degrades the coolant corrosion
protection.
Do not add alcohol, methanol, brine or any engine coolants mixed with alcohol or methanol
antifreeze. These can cause engine damage from overheating or freezing.
Ford Motor Company does NOT recommend the use of recycled engine coolant in vehicles
originally equipped with Motorcraft® Specialty Orange Engine Coolant since a Ford-approved
recycling process is not yet available.

Principles of Operation
Engine coolant flows primarily from the engine to the radiator circuit and back to the coolant pump.
Coolant is sent from the coolant pump through the engine block and cylinder heads. A separate circuit
from the engine also feeds the heater core with coolant. The coolant pump is operated by engine
rotation through a pulley which is driven by the accessory drive belt to circulate the coolant. The coolant
thermostat is a control valve actuated by coolant temperature. When the thermostat is closed, coolant
flow bypasses the radiator circuit and returns to the coolant pump. When the thermostat is opened,
coolant flows through the radiator circuit to transfer engine generated heat to the outside air.
The degas bottle removes air from the cooling system, allows for coolant expansion and system
pressurization, replenishes coolant to the cooling system and serves as the location for service fill.
The cooling fan draws air through the radiator to help cool the system coolant as it passes through the
radiator.
The thermostat monitor is a function of the PCM and is designed to verify correct thermostat operation.
The monitor executes once per drive cycle and has a monitor run duration of 300-800 seconds. If a
malfunction occurs, DTC P0125 or P0128 is set, and the Malfunction Indicator Lamp (MIL) is illuminated.
Inspection and Verification
WARNING: Always allow the engine to cool before opening the cooling system. Do not
unscrew the coolant pressure relief cap when the engine is operating or the cooling system is
hot. The cooling system is under pressure; steam and hot liquid can come out forcefully when
the cap is loosened slightly. Failure to follow these instructions may result in serious personal
injury.
NOTICE: The engine cooling system is filled with Motorcraft® Specialty Orange Engine Coolant.
Always fill the cooling system with the manufacturer's specified coolant. Chemically flush the
cooling system if a non-specified coolant has been used. Refer to Cooling System Flushing in
this section. Failure to follow these instructions may damage the engine or cooling system.
NOTE: During normal vehicle operation, Motorcraft Specialty Orange Engine Coolant may change color
from orange to pink or light red. As long as the engine coolant is clear and uncontaminated, this color
change does not indicate the engine coolant has degraded nor does it require the engine coolant to be
drained, the system to be flushed, or the engine coolant to be replaced.
NOTE: Vehicles have the pressure relief cap on the degas bottle and no radiator cap.
1. Verify the customer concern.
2. Visually check the engine coolant level at the degas bottle when the system is cold.
3. Make sure the pressure relief cap is installed correctly.
4. Record any cooling system DTCs retrieved. Refer to the PCM DTC chart in this section for DTC
descriptions.
5. NOTE: Take note of any coolant odor or steam coming from cooling system components.
If the system coolant is filled correctly and no DTCs associated with fail-safe cooling are retrieved,
verify the customer concern by operating the engine to duplicate the condition.
6. Visually inspect for obvious signs of any mechanical or electrical damage.

7. If the inspection reveals an obvious concern that can be readily identified, repair it as necessary.
Test the system for normal operation.
8. Inspect the coolant condition.
1. Inspect the coolant color.
Discoloration may indicate that incorrect coolant may have been added to the
system. Use of incorrect (green or yellow in color) coolant degrades the corrosion
protection of Motorcraft® Specialty Orange Engine Coolant. Addition of Motorcraft®
Specialty Green Engine Coolant may cause the color to appear to be a murky
green-brown color. The addition of Motorcraft® Premium Gold Engine Coolant,
however, may not change the color or appearance of the orange colored coolant.
Detection of contamination with Motorcraft® Premium Gold Engine Coolant is
determined by the presence of nitrite. If contamination with Motorcraft® Premium
Gold Engine Coolant is suspected, test the coolant with the 3-Way HD Antifreeze
Coolant Test Kit. Follow the directions on the packaging. If the incorrect coolant has
been added to the cooling system, flush the system and refill with the correct
mixture of distilled water and Motorcraft® Specialty Orange Engine Coolant. Refer
to Cooling System Flushing in this section.
A darker orange with the presence of debris could indicate a commercially available
stop leak may have been used and could result in loss of coolant flow to critical
parts of the engine. If sediment is present, flush the system and refill with the correct
mixture of distilled water and Motorcraft® Specialty Orange Engine Coolant. Refer
to Cooling System Flushing in this section.
A light or reddish brown color indicates that rust may be present in the cooling
system. Flush the system and refill with the correct mixture of distilled water and
Motorcraft® Specialty Orange Engine Coolant. Refer to Cooling System Flushing in
this section.
An iridescent sheen on top of the coolant could indicate a trace of oil is entering the
system. For engine diagnosis, refer to Section 303-00 . Flush the system and refill
with the correct mixture of distilled water and Motorcraft® Specialty Orange Engine
Coolant. Refer to Cooling System Flushing in this section.
A milky brown color may indicate that engine oil is entering the cooling system.
Pressure test the cooling system. Refer to component tests in this section. If engine
oil is suspected, the cause of the leak may be internal to the engine. For engine
diagnosis, refer to Section 303-00 . Flush the system and refill with the correct
mixture of distilled water and Motorcraft® Specialty Orange Engine Coolant. Refer
to Cooling System Flushing in this section.
2. If the engine coolant appearance is acceptable, test the engine coolant freezing point
range with the Coolant/Battery Refractometer. The freezing point should be in the range of
-50°C to -26°C (-58°F to -15°F). If the vehicle is driven in cold climates less than -37°C (34°F), it may be necessary to increase the coolant concentration to get adequate freeze
protection. Recommended coolant concentration is 50/50 ethylene glycol to distilled water.
Maximum coolant concentration is 60/40 for cold weather areas.
Minimum coolant concentration is 40/60 for warm weather areas.
3. Adjust coolant range and level if necessary:
If coolant is low, add specified coolant mixture only.
If the engine coolant tests too weak, remove some of the engine coolant and add
undiluted engine coolant until the readings are within acceptable levels.
If the engine coolant tests strong, remove some of the engine coolant and add
distilled water until the readings are within acceptable levels.
9. If an obvious cause for an observed or reported concern is found, correct the cause and test the
system for normal operation before proceeding to the next step.
10. NOTE: Make sure to use the latest scan tool software release.
If the cause is not visually evident, connect the scan tool to the Data Link Connector (DLC).
11. NOTE: The Vehicle Communication Module (VCM) LED prove-out confirms power and ground
from the DLC are provided to the VCM .
If the scan tool does not communicate with the VCM :
check the VCM connection to the vehicle.
check the scan tool connection to the VCM .
refer to Section 418-00 , No Power To The Scan Tool, to diagnose no power to the scan
tool.
12. If the scan tool does not communicate with the vehicle:
verify the ignition key is in the ON position.
verify the scan tool operation with a known good vehicle.
refer to Section 418-00 to diagnose no response from the PCM.
13. Carry out the network test.
If the scan tool responds with no communication for one or more modules, refer to Section
418-00 .
If the network test passes, retrieve and record Continuous Memory Diagnostic Trouble
Codes (CMDTCs).
14. Clear the continuous DTCs and carry out the self-test diagnostics PCM.
15. If the DTCs recovered are related to the concern, go to the PCM DTC Chart. For all other PCM
DTCs, refer to Section 303-14 .
16. If no DTCs related to the concern are retrieved, GO to Symptom Chart .

The engine cooling system maintains the engine temperature during operation. Correct coolant flow
through the engine, radiator and remainder of cooling system passages and components is essential to
maintaining a correct engine temperature.
Engine coolant flows primarily from the engine to the radiator circuit and back to the coolant pump.
Coolant is sent from the coolant pump through the engine block and cylinder heads. A separate circuit
from the engine also feeds the heater core with coolant. The coolant pump, operated by engine rotation
through a pulley driven by the accessory drive belt circulates the coolant. The coolant thermostat is a
control valve actuated by coolant temperature. When the thermostat is closed, coolant flow bypasses the
radiator circuit and returns to the coolant pump. When the thermostat is opened, coolant flows through
the radiator circuit to transfer engine-generated heat to the outside air.
Engine overheating generally occurs when there is a disruption in the ability to control either coolant flow
at the correct rate, the inability to transfer heat from the engine through the coolant (including low
coolant) or an inability to transfer engine-generated heat to the outside air through the radiator.
This pinpoint test is intended to diagnose the following:

the engine, radiator and remainder of cooling system passages and components is essential to
maintaining a correct engine temperature.
Engine coolant flows primarily from the engine to the radiator circuit and back to the coolant pump.
Coolant is sent from the coolant pump through the engine block and cylinder heads. A separate circuit
from the engine also feeds the heater core with coolant. The coolant pump, operated by engine rotation
through a pulley driven by the accessory drive belt, circulates the coolant. The coolant thermostat is a
control valve actuated by coolant temperature. When the thermostat is closed, coolant flow bypasses the
radiator circuit and returns to the coolant pump. When the thermostat is opened, coolant flows through
the radiator circuit in order to transfer engine generated heat to the outside air.
Concerns of engine inability to reach normal operating temperature typically occur when the rate of
coolant flow through some coolant circuits (radiator, heater core) is more than expected given the
conditions, or when the electric cooling fan operates all of the time. Heat is not allowed to build in the
engine because a heat exchanger is removing too much heat, including the radiator, heater core and oil
cooler. In addition, perceived concerns that the engine does not reach normal operating temperature can
be related to a low coolant level or trapped air which does not allow for hot coolant to be available at the
heater core, an inoperative climate control system, or for concerns perceived or related to an incorrect
engine temperature gauge indication.
DTC P0125 (Insufficient Coolant Temp for Closed Loop Fuel Control) — Indicates the Engine
Coolant Temperature (ECT) sensor has not achieved the required temperature level to enter
closed loop operating conditions within a specified amount of time after starting the engine.
DTC P0128 (Coolant Thermostat [Coolant Temp Below Thermostat Regulating Temperature]) —
Indicates that the thermostat monitor has not achieved the required engine operating temperature
within a specified amount of time after starting the engine.
This pinpoint test is intended to diagnose the following:
Low coolant level
Thermostat
ECT indicator system (gauge)
Engine cooling fan always on
PINPOINT TEST C: THE ENGINE DOES NOT REACH NORMAL OPERATING TEMPERATURE
WARNING: Always allow the engine to cool before opening the cooling system. Do not
unscrew the coolant pressure relief cap when the engine is operating or the cooling system is
hot. The cooling system is under pressure; steam and hot liquid can come out forcefully when
the cap is loosened slightly. Failure to follow these instructions may result in serious personal
injury.

Component Tests
Cooling System Pressure Test
WARNING: Always allow the engine to cool before opening the cooling system. Do not
unscrew the coolant pressure relief cap when the engine is operating or the cooling system is
hot. The cooling system is under pressure; steam and hot liquid can come out forcefully when
the cap is loosened slightly. Failure to follow these instructions may result in serious personal
injury.
NOTE: Vehicles have the pressure relief cap on the degas bottle and no radiator cap.
1. Turn the engine OFF.
2. Check the engine coolant level. Adjust the coolant level as necessary.
3. Attach the D-Gas Adapter to the degas bottle nipple and overflow hose. Install the Radiator
Tester to the quick connect fitting of the D-Gas Adapter.
4. NOTICE: Do not pressurize the cooling system beyond the maximum pressure listed in the
specifications table in this section or cooling system components may be damaged.
NOTE: If the plunger of the pressure tester is pressed too fast, an incorrect pressure reading
results.
Slowly press the plunger of the pressure test pump until the pressure gauge reading stops
increasing and note the highest pressure reading obtained. If the pressure reading exceeds the
maximum cap pressure listed in the specifications table, install a new pressure relief cap.
5. If the system does not hold pressure, remove the pressure relief cap and wash it in clean water to
dislodge all of the foreign material from the gasket. Check the sealing surface in the filler neck of
the degas bottle for nicks or cuts. Use fine sandpaper or emery cloth to remove nicks and cuts.
Place a shop cloth in the filler neck to prevent debris from falling into the degas bottle. If nicks or
cuts are too deep to remove, install a new degas bottle. Install the pressure relief cap.
6. Pressurize the engine cooling system as described in Step 4. Observe the gauge reading for
approximately 2 minutes. Pressure should not drop during this time. If the pressure drops, inspect
for leaks and repair as necessary.
7. If no leaks are found and the pressure drops, the pressure relief cap may be leaking. Install a new
pressure relief cap and retest the system.
8. If no leaks are found after a new pressure relief cap is installed, and the pressure drops, the leak
may be internal to the engine. Inspect the coolant for engine oil and the engine oil for coolant.
Refer to Section 303-00 to diagnose the engine.
9. Release the system pressure by loosening the pressure relief cap. Check the coolant level and
adjust as necessary.
Thermostat
A new thermostat should be installed only after the following tests and checks have been carried out:
Pinpoint Test A, B or C
Thermostat Visual Inspection
Thermostat Visual Inspection
1. Remove the thermostat.
2. Examine the thermostat for signs of damage including:
Valve not fully seated (light visible through the valve)
Foreign material lodged in the main valve
Bent or broken frame or flange
Bent or broken spring
Bent or broken valve or valve stem
Wax leaking from wax reservoir or a bulge in the reservoir
Any other damage or distortion
3. NOTE: If no damage is found during the inspection, do not attempt to open the thermostat using
hot water or other heat sources. This method is not an accurate means to test the function of the
thermostat and may damage the thermostat.
If damage is found during the inspection, remove any foreign material or broken pieces and install
a new thermostat.
4. If no damage is found during the inspection, continue troubleshooting the system concern. Go to
the Symptom Chart for further instructions.
Radiator Leak Test, Removed From Vehicle
NOTICE: Never leak test an aluminum radiator in the same water that copper/brass radiators are
tested in. Flux and caustic cleaners may be present in the cleaning tank and they will damage
aluminum radiators.
NOTE: Clean the radiator before leak testing to avoid contamination of tank.
Leak test the radiator in clean water with air pressurized to the maximum pressure listed in the
Specifications.

WARNING: Always allow the engine to cool before opening the cooling system. Do
not unscrew the coolant pressure relief cap when the engine is operating or the cooling
system is hot. The cooling system is under pressure; steam and hot liquid can come out
forcefully when the cap is loosened slightly. Failure to follow these instructions may result
in serious personal injury.
NOTICE: The coolant must be recovered in a suitable, clean container for reuse. If the
coolant is contaminated, it must be recycled or disposed of correctly. Using contaminated
coolant may damage the engine or cooling system components.
NOTE: During normal vehicle operation, Motorcraft Specialty Orange Engine Coolant may
change color from orange to pink or light red. As long as the engine coolant is clear and
uncontaminated, this color change does not indicate the engine coolant has degraded nor does it
require the engine coolant to be drained, the system to be flushed, or the engine coolant to be
replaced.
Release the pressure in the cooling system by slowly turning the pressure relief cap one half turn
counterclockwise. When the pressure has been released, remove the pressure relief cap.
3. Place a suitable container below the lower radiator hose.
Release the clamp, disconnect the lower radiator hose from the radiator and allow the
coolant to drain.
Filling and Bleeding with a Vacuum Cooling System Filler
NOTICE: The engine cooling system is filled with Motorcraft® Specialty Orange Engine Coolant.
Always fill the cooling system with the manufacturer's specified coolant. If a non-specified
coolant has been used the cooling system must be chemically flushed. Refer to Cooling System
Flushing in this section. Failure to follow these instructions may damage the engine or cooling
system.
NOTICE: Engine coolant provides freeze protection, boil protection, cooling efficiency and
corrosion protection to the engine and cooling components. In order to obtain these protections,
the engine coolant must be maintained at the correct concentration and fluid level in the coolant
expansion tank.
To maintain the integrity of the coolant and the cooling system:
Add Motorcraft® Specialty Orange Engine Coolant or equivalent meeting Ford
specification WSS-M97B44-D (orange color).
Do not add or mix with any other type of engine coolants. Mixing coolants degrades the
coolant's corrosion protection.
Do not add alcohol, methanol or brine, or any engine coolants mixed with alcohol or
methanol antifreeze. These can cause engine damage from overheating or freezing.
Ford Motor Company does NOT recommend the use of recycled engine coolant in vehicles
originally equipped with Motorcraft® Specialty Orange Engine Coolant since a Fordapproved recycling process is not yet available.
1. Connect the lower radiator hose to the radiator and position the clamp.
2. Install the vacuum cooling system filler and follow the manufacturer's instructions to fill and bleed
the cooling system.
Recommended coolant concentration is 50/50 ethylene glycol to distilled water.
For extremely cold climates (less than -37°C [-34°F]):
It may be necessary to increase the coolant concentration above 50%.
NEVER increase the coolant concentration above 60%.
Maximum coolant concentration is 60/40 for cold weather areas.
A coolant concentration of 60% will provide freeze point protection down to -50°C (58°F).
Engine coolant concentration above 60% will decrease the overheat protection
characteristics of the engine coolant and may damage the engine.
For extremely hot climates:
It is still necessary to maintain the coolant concentration above 40%.
NEVER decrease the coolant concentration below 40%.
Minimum coolant concentration is 40/60 for warm weather areas.
A coolant concentration of 40% will provide freeze point protection down to -26°C (15°F).
Engine coolant concentration below 40% will decrease the corrosion and freeze
protection characteristics of the engine coolant and may damage the engine.
Vehicles driven year-round in non-extreme climates should use a 50/50 mixture of engine
coolant and distilled water for optimum cooling system and engine protection.

1. Remove the A/C tube bracket nut and detach the bracket from the stud.
To install, tighten to 10 Nm (89 lb-in).
2.
WARNING: Always allow the engine to cool before opening the cooling system. Do not
unscrew the coolant pressure relief cap when the engine is operating or the cooling system is
hot. The cooling system is under pressure; steam and hot liquid can come out forcefully when
the cap is loosened slightly. Failure to follow these instructions may result in serious personal
injury.
NOTE: During normal vehicle operation, Motorcraft Specialty Orange Engine Coolant may change color
from orange to pink or light red. As long as the engine coolant is clear and uncontaminated, this color
change does not indicate the engine coolant has degraded nor does it require the engine coolant to be
drained, the system to be flushed, or the engine coolant to be replaced.

Fuel Charging and Controls
Sequential Multi-Port Fuel Injection (SFI)
System Overview
WARNING: Do not smoke, carry lighted tobacco or have an open flame of any type when
working on or near any fuel-related component. Highly flammable mixtures are always present
and may be ignited. Failure to follow these instructions may result in serious personal injury.
The fuel charging and controls system is:
a Sequential Multi-Port Fuel Injection (SFI) system.
Pulse Width Modulated (PWM).
Mass Air Flow (MAF) sensor controlled.
Component List
The fuel charging and controls system consists of the:
Throttle Body (TB)
fuel injectors
fuel rail
Fuel Pump (FP) control module
System Components
Throttle Body (TB)
The TB :
controls air supply to the intake manifold by electronically positioning the throttle plate.
is not adjustable.
cannot be cleaned.
Fuel Injectors
The fuel injectors:
NOTICE: Handle the fuel injectors and fuel rail with extreme care to prevent damage to sealing
areas and sensitive fuel-metering orifices.
are electronically operated by the PCM.
atomize the fuel as the fuel is delivered.
each have an internal solenoid that opens a needle valve, injecting fuel into the intake port in the
cylinder head.
are deposit resistant.
Fuel Rail
The fuel rail receives fuel from the fuel supply tube and delivers fuel to the fuel injectors
NOTICE: Handle the fuel injectors and fuel rail with extreme care to prevent damage to sealing
areas and sensitive fuel-metering orifices.
Fuel Pump (FP) Control Module
The FP control module is electronically operated by the PCM and controls voltage to the FP depending
on engine load.
System Operation
Fuel is metered into each intake port in a sequential firing order. Fuel injectors pulse to follow engine
firing order, in accordance with engine demand on a tuned intake manifold.
The basic fuel requirement of the engine is determined from the data supplied to the PCM by the MAF
sensor. The MAF sensor measures the amount of air being drawn into the engine.
The various sensors detect any changes in the operating conditions and send signals to the PCM. This
permits the PCM to control the opening duration (pulse width) of the fuel injectors and maintain optimum
exhaust emission control and engine performance for all operating conditions.

3. Eliminate all other non-belt related noises that could cause belt misdiagnosis, such as A/C
compressor engagement chirp, A/C slugging noise, power steering cavitations at low
temperatures, Variable Camshaft Timing (VCT) tick or generator whine.
4. If a concern is found, correct the condition before proceeding to the next step.
V-Ribbed Serpentine Drive Belt With Cracks Across Ribs
5. Check the belt for cracks. Up to 15 cracks in a rib over a distance of 100 mm (4.0 in) can be
considered acceptable. If cracks exceed this standard, install a new belt.
V-Ribbed Serpentine Belt With Piling
NOTE: Piling is an excessive buildup in the V-grooves of the belt.
6. The condition of the V-ribbed drive belt should be compared against the illustration and
appropriate action taken.
1. Small scattered deposits of rubber material. This is not a concern, therefore, installation of
a new belt is not required.
2. Longer deposit areas building up to 50% of the rib height. This is not considered a
durability concern, but it can result in excessive noise. If noise is apparent, install a new
belt.
3. Heavy deposits building up along the grooves resulting in a possible noise and belt stability
concern. If heavy deposits are apparent, install a new belt.
V-Ribbed Serpentine Belt With Chunks of Rib Missing
7. There should be no chunks missing from the belt ribs. If the belt shows any evidence of this,
install a new accessory drive belt.
8. If the concern is not visually evident, verify the symptom and GO to Symptom Chart .

Drive Belt — Noise/Flutter
NOTICE: Under no circumstances should the accessory drive belt, tensioner or pulleys have any
fluids or belt dressing applied to them as damage to the belt material and tensioner damping
mechanism may occur.
Drive belt chirp occurs due to pulley misalignment or excessive pulley runout. It can be the result of a
damaged or incorrectly aligned grooved pulley.
To correct, determine the area where the noise comes from. Check each of the pulleys in that area with
a straightedge to the crankshaft pulley. Look for accessory pulleys out of position in the fore/aft direction
or at an angle to the straightedge.
Drive belt squeal may be an intermittent or constant noise that occurs when the drive belt slips on an
accessory pulley under certain conditions.
A short intermittent squeal may occur during engine start up and shut down or during very rapid engine
acceleration and decelerations, such as:
Wide Open Throttle (WOT) 1-2 and 2-3 shifts or 2-3 and 3-4 back-out shifts on automatic
transmissions.
WOT 1-2 and 2-3 shifts and any combination of rapid downshifting on manual transmissions.
These special short-term transient events are expected, and are due to the higher system inertias
required to meet the electrical and cooling demands on today's vehicle systems. Constant or reoccurring
drive belt squeal can occur:
if the A/C discharge pressure goes above specifications:
the A/C system is overcharged.
the A/C condenser core airflow is blocked.
the A/C anti-slugging strategy executes after a long hot heat soak.
if the A/C off equalized pressure (the common discharged and suction pressure that occurs after
several minutes) exceeds specifications.
if any of the accessories or idler pulley(s) are damaged or have a worn or damaged bearing. All
accessories should be rotatable by hand in the unloaded condition. If not, inspect the accessory.
if there is evidence of fluid contamination on the accessory drive belt. When the drive belt has
been exposed to fluid contamination during vehicle operation, such as leaks from the power
steering system, A/C system or cooling system, clean all pulleys with soap and water, rinse with
clean water and install a new accessory drive belt. If the drive belt has been exposed to fluids in a
localized area during routine vehicle service, such as replacement of hoses or fluids, the drive
belt and pulleys should be washed with soap and water immediately (prior to starting the engine),
and rinsed with clean water.
Install a new accessory drive belt if the drive belt is worn or damaged.
Drive Belt — Incorrect Installation
NOTICE: Incorrect accessory drive belt installation will cause excessive drive belt wear and may
cause the drive belt to come off the pulleys.
Non-standard accessory drive belts can track differently or incorrectly. If an accessory drive belt tracks
incorrectly, install a new accessory drive belt to avoid performance failure or loss of the drive belt.
Incorrect Installation
Correct Installation
With the engine running, check accessory drive belt tracking on all pulleys. If the edge of the accessory
drive belt rides beyond the edge of the pulleys, noise and premature wear will occur. Make sure the
accessory drive belt rides correctly on the pulley. If an accessory drive belt tracking condition exists,
proceed with the following:
Visually check the accessory drive belt tensioner for damage and wear, especially the mounting
pad surface and arm alignment. If the accessory drive belt tensioner is not installed correctly, the
mounting surface pad will be out of position. If the tensioner arm is worn, the arm will be out of
alignment. Either of these conditions will result in chirp and squeal noises.
With the engine running, visually observe the grooves in the pulleys (not the pulley flanges or the
pulley forward faces) for excessive wobble. Install new components as necessary.
Check all accessories, mounting brackets and the accessory drive belt tensioner for any
interference that would prevent the component from mounting correctly. Correct any interference
condition and recheck the accessory drive belt tracking.
Tighten all accessories, mounting brackets and accessory drive belt tensioner retaining hardware
to specification. Recheck the accessory drive belt tracking.

Principles of Operation — Without Intelligent Access (IA)
NOTE: This vehicle is equipped with Passive Anti-Theft System (PATS) that disables the engine if an
unprogrammed PATS key is used or an invalid PCM ID is received. PATS is controlled by the Instrument
Panel Cluster (IPC). If there is a PATS concern that caused the engine to be disabled, the anti-theft light
flashes rapidly in the IPC . Refer to Section 419-01B to diagnose a PATS concern.
The starting system is electronically controlled by the PCM. The PCM receives the following inputs:
Correctly coded ignition key from the IPC
Clutch pedal applied from the Clutch Pedal Position (CPP) switch (vehicles equipped with manual
transaxle)
Transaxle in PARK or NEUTRAL from the Transmission Range (TR) sensor (vehicles equipped
with automatic transaxle)
Request to start the engine, ignition switch in the START position
Under normal operation when the ignition is turned to the START position the IPC generates a key
verification message. It sends this message to the PATS transceiver. The transceiver reads the key and
sends a key verification message back to the IPC . If the message received does not match the key
verified in the IPC memory, the engine will not crank and start. Once the IPC determines the correct
programmed key was used to START the vehicle, the IPC sends the PCM a request to crank and start
the engine. When the PCM receives the message, it generates a response and sends it back to the
IPC . If the response from the PCM does not match the response in the IPC memory, PATS is not
enabled and the engine does not crank. If both the key verification and PCM ID pass, PATS is enabled.
The PCM recognizes the correct electronically coded passive key and provides voltage and ground to
the starter relay coil. The starter relay coil is energized causing the relay contacts to close providing
voltage to the starter solenoid, allowing the starter motor to crank and start the engine. The PCM
disengages the starter once an engine rpm threshold is reached, a set crank time is exceeded or the
ignition is turned OFF. For additional information, refer to Section 419-01B .
Vehicles equipped with an automatic transaxle have a TR sensor. The TR sensor prevents operation of
the starter unless the transaxle is in NEUTRAL or PARK.
Vehicles equipped a manual transaxle have a CPP switch. The CPP switch prevents operation of the
starter unless the clutch pedal is fully pressed.
Principles of Operation — With Intelligent Access (IA)
NOTE: This vehicle is equipped with Passive Anti-Theft System (PATS) that disables the engine if an
unprogrammed PATS key is used or an invalid PCM ID is received. PATS is controlled by the Remote
Function Actuator (RFA) module. If there is a PATS concern that caused the engine to be disabled, the
anti-theft light flashes rapidly in the Instrument Panel Cluster (IPC). Refer to Section 419-01B to
diagnose a PATS concern.
The Intelligent Access (IA) starting system is electronically controlled by the RFA module which acts as
the PATS control function. The RFA module receives the following inputs:
Correctly coded ignition key from PATS
Clutch pedal applied input from the Clutch Pedal Position (CPP) switch (vehicles equipped with
manual transaxle)
Transaxle in PARK or NEUTRAL from the Transmission Control Module (TCM) (vehicles
equipped with automatic transaxle)
Request to start the engine, start/stop switch is pushed
Brake pedal applied input (automatic transaxle)
During a start event, the start/stop button is pushed in combination with either the brake or clutch pedal
input. The RFA module receives a request to start the engine. The RFA module recognizes the correct
electronically coded passive key and provides voltage to the starter relay coil and signals the PCM. The
PCM recognizes the correct inputs and provides ground to energize the relay coil and close the relay
contacts. The starter relay contacts close, providing voltage to the starter solenoid, allowing the starter to
crank and start the engine. The PCM disengages the starter once an engine rpm threshold is reached, a
set crank time is exceeded or the stop/start button is pressed indicating an engine shutdown request.
Vehicles equipped with an automatic transaxle have a TR sensor. The TR sensor prevents operation of
the starter unless the transaxle is in NEUTRAL or PARK.
Vehicles equipped a manual transaxle have a CPP switch. The CPP switch prevents operation of the
starter unless the clutch pedal is fully pressed.
Inspection and Verification
WARNING: Always disconnect the battery ground cable at the battery before disconnecting
the starter motor battery terminal lead. If a tool is shorted at the starter motor battery terminal,
the tool can quickly heat enough to cause a skin burn. Failure to follow this instruction may
result in serious personal injury.
NOTE: Make sure the anti-theft system is functioning correctly before carrying out a logical starting
system diagnosis. Address anti-theft system concerns before continuing. Refer to Section 419-01B .
1. Verify the customer concern.
2. Remove the accessory drive belt. Refer to Section 303-05 . Verify the crankshaft and each of the

Pinpoint Tests
Pinpoint Test A: The Engine Does Not Crank — Without Intelligent Access
Refer to Wiring Diagrams Cell 20 , Starting System for schematic and connector information.
Normal Operation
Under normal operation the ignition switch is turned to the START position, the PCM receives a request
to start the engine. The PCM receives a signal from theTransmission Control Module (TCM) that the
vehicle is in PARK or NEUTRAL as determined by the TR sensor (vehicles equipped with an automatic
transaxle) or from the Clutch Pedal Position (CPP) switch indicating the clutch pedal is fully pressed
(vehicles equipped with manual transaxle). The PCM supplies voltage and ground to energize the starter
relay coil. The energized coil causes the starter relay contacts to close. This allows voltage to be
supplied from Battery Junction Box (BJB) fuse 11 (30A) to the starter solenoid. The starter solenoid is
grounded at the starter. Energizing the starter solenoid closes the solenoid contacts allowing voltage
directly from the battery to the starter, engaging the starter drive into the ring gear causing the engine to
crank and start. The PCM disengages the starter once an engine rpm threshold is reached, a set crank
time is exceeded or the ignition is turned OFF.

Refer to Wiring Diagrams Cell 20 , Starting System for schematic and connector information.
Normal Operation
Under normal operation the start/stop switch, when pushed in combination with pressing either the brake
or clutch pedal (depending upon transaxle), provides the Remote Function Actuator (RFA) module a
request to start the engine. The RFA module and PCM receive a signal from the Transmission Control
Module (TCM) that the vehicle is in PARK or NEUTRAL (vehicles equipped with an automatic transaxle)
or from the Clutch Pedal Position (CPP) switch when the clutch pedal is fully pressed (vehicles equipped
with manual transaxle). The RFA module supplies voltage to the starter relay coil and signals the PCM
to provide ground to the relay coil. The energized coil causes the starter relay contacts to close. This
allows voltage to be supplied from Battery Junction Box (BJB) fuse 11 (30A) to the starter solenoid. The
starter solenoid is grounded at the starter. Energizing the starter solenoid closes the solenoid contacts
allowing voltage directly from the battery to the starter, engaging the starter drive into the ring gear
causing the engine to crank and start. The PCM disengages the starter once an engine rpm threshold is
reached, a set crank time is exceeded or the stop/start button is pressed indicating engine shut down.

Refer to Wiring Diagrams Cell 20 , Starting System for schematic and connector information.
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the
correct probe adapter(s) may damage the connector.
Normal Operation — (Without Intelligent Access)
When the ignition is turned to the START position, the PCM receives a request to start the engine and
supplies voltage to the starter relay coil. The PCM monitors the start request circuit for faults. If voltage
is detected on the start request circuit and the starter relay is not in an active state, the PCM sets a DTC.
DTC P0617:12 (Starter Relay Circuit High: Circuit Short to Battery) — sets when the PCM detects
excessive current on the starter relay circuit and the output is not activated.
Normal Operation — With Intelligent Access (IA)
When the start/stop switch is pressed and released along with either the brake pedal (vehicles equipped
with automatic transaxle) or Clutch Pedal Position (CPP) switch (vehicles equipped with manual
transaxle) input, the Remote Function Actuator (RFA) module receives a request from the Intelligent
Access (IA) key to start the engine. The RFA module then supplies voltage to the starter relay coil. The
RFA module monitors the start request circuit for faults. If voltage is detected on the start request circuit
and the starter relay is not in an active state, the RFA module sets a DTC.
DTC P0615:12 (Starter Relay Circuit High: Circuit Short to Battery) — sets when the RFA module
detects current output above threshold on the starter relay circuit and the output is not activated.

Component Tests
WARNING: Always disconnect the battery ground cable at the battery before disconnecting
the starter motor battery terminal lead. If a tool is shorted at the starter motor battery terminal,
the tool can quickly heat enough to cause a skin burn. Failure to follow this instruction may
result in serious personal injury.
Always make the Fluke 77-IV Digital Multimeter connections at the component terminal rather than at
the wiring end connector. Making a connection at the wiring end connector could result in false readings
because the meter will not pick up a high resistance between the wiring connector and the component.
Starter Motor — Feed Circuit Test
1. Make sure the battery is fully charged. Carry out the battery condition test. Refer to Diagnosis and
Testing in Section 414-01 .
2. Connect a remote starter switch between the starter solenoid "S" terminal and the battery positive
(+) terminal.
3. Connect the Fluke 77-IV Digital Multimeter positive lead to the battery positive (+) post. Connect
the negative lead to the "M" terminal.
4. Engage the remote starter switch. Read and record the voltage. The voltage reading should be
0.5 volt or less.
5. If the voltage reading is 0.5 volt or less, go to the Starter Motor — Ground Circuit Component
Test.
6. If the voltage reading is greater than 0.5 volt, this is an indication of excessive resistance in the
connections, the positive battery cable or in the starter solenoid. Move the Fluke 77-IV Digital
Multimeter negative lead to the starter solenoid "B" terminal and repeat the test. If the voltage
reading at the "B" terminal is lower than 0.5 volt, the concern is either in the connections at the
starter solenoid or in the solenoid contacts.
7. Remove the cables from solenoid "B", "S" and "M" terminals. Clean the cables and connections
and reinstall the cables to the correct terminals. Repeat Steps 3 through 6. If the voltage drop
reading is still greater than 0.5 volt when checked at the "M" terminal and less than 0.5 volt when
checked at the "B" terminal, the concern is in the solenoid contacts. Install a new starter motor.
8. If the voltage reading taken at the solenoid "B" terminal is still greater than 0.5 volt after cleaning
the cables and the connections at the solenoid, the concern is either in the positive (+) battery
cable connection or in the positive battery cable itself. Clean the positive (+) battery cable
connection. If this does not solve the problem, install a new positive battery cable. Refer to
Section 414-01 .
Starter Motor — Ground Circuit Test
A no or slow crank condition can be caused by excessive resistance in the ground or return portion of
the cranking circuit. Check the voltage drop in the ground circuit as follows:
1. Connect the Fluke 77-IV Digital Multimeter positive lead to the starter motor housing (make sure
the connection is clean and free of rust or grease). Connect the negative lead to the negative (-)
battery terminal.
2. Engage the remote starter switch and crank the engine. Read and record the voltage reading.
The reading should be 0.5 volt or less.
3. If the voltage is greater than 0.5 volt, clean the negative cable connections at the battery, the
body ground connections and the starter ground connections. Retest.
4. If the voltage is greater than 0.5 volt, install a new negative battery cable. If the voltage reading is
less than 0.5 volt and the engine still does not crank or cranks slowly, install a new starter motor.

System Overview
NOTE: The vehicle emission vacuum routing diagrams are contained in the Description and Operation
subsection of Evaporative Emissions. Refer to Section 303-13 .
NOTE: Do not permanently remove or render inoperative any part of the vehicle emission control system
including related hardware. Failure to comply may violate applicable state and federal laws.
The crankcase ventilation system gathers blow-by vapors from the crankcase and returns them to the
intake manifold and air cleaner for combustion.
Component List
The crankcase ventilation system consists of the following components:
a crankcase vent oil separator located on the engine block
a valve cover vent hose connected to the air cleaner
a crankcase vent oil separator hose connected to the intake manifold
a crankcase pressure regulator located inside the crankcase vent oil separator housing
System Components
The crankcase vent oil separator removes vaporized oil from the blow-by vapors and returns the
separated oil to the crankcase.
The crankcase pressure regulator controls the return of the blow-by pressure to the intake manifold
through the crankcase vent oil separator hose.
The valve cover vent hose vents excessive crankcase pressure to the air cleaner and allows fresh air
into the crankcase to prevent premature degradation of the engine oil.
System Operation
During high intake manifold vacuum situations the blow-by pressure flows through the crankcase
pressure regulator and is returned to the intake manifold through the crankcase vent oil separator hose.
During low intake manifold vacuum situations the crankcase pressure regulator restricts flow to the
intake manifold causing blow-by pressure to flow through the valve cover vent hose to the air cleaner.

2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Electronic Engine Controls
The electronic engine controls consist of the following:
PCM
Camshaft Position (CMP) sensor (2 required)
Clutch Pedal Position (CPP) switch (manual transmission only)
Crankshaft Position (CKP) sensor
Mass Air Flow (MAF) sensor
Heated Oxygen Sensor (HO2S)
Catalyst Monitor Sensor (CMS)
Knock Sensor (KS) (2 required)
Engine Coolant Temperature (ECT) sensor
Variable Camshaft Timing (VCT) oil control solenoid (2 required)
The PCM:
accepts input from various engine sensors and generates output signals to control fuel injection,
ignition and emissions.
The CMP sensor:
sends the PCM a signal indicating camshaft position used for fuel synchronization.
The CPP sensor:
sends a signal through the instrument cluster to the PCM. The PCM needs this signal to improve
engine running performance during gear changes.
The CKP sensor:
sends the PCM a signal indicating crankshaft position.
The MAF sensor:
uses a hot-film element to measure the amount of air entering the engine.
The HO2S :
creates a voltage signal dependent on exhaust oxygen content.
provides feedback information to the PCM used to calculate fuel delivery.
The CMS :
monitors oxygen content after it flows through the catalytic converter.
provides a voltage to the PCM used to calculate catalytic converter integrity.
The KS :
is used to detect engine detonation.
sends a voltage signal to the PCM.
The ECT sensor:
sends the PCM a signal indicating engine coolant temperature.
voltage decreases as coolant temperature increases.
The VCT oil control solenoid:
is an electronic solenoid that actuates the flow of oil to the variable camshaft. Once the PCM
transmits a signal, the solenoid moves a valve spool, directing oil into the camshaft phaser cavity.
This action changes valve timing by either inducing an advance or retard condition. The camshaft
is, thereby repositioned in relation to crankshaft timing and allows for optimum engine
performance and lower emissions

Wheel Alignment Angles
Camber
NOTE: Wheel alignment angles can be affected by subframe position. Subframe alignment may be
necessary if wheel alignment cannot be achieved.
Negative and Positive Camber
Camber is the vertical tilt of the wheel when viewed from the front. Camber can be positive or negative
and has a direct effect on tire wear. The camber setting is not adjustable.
Caster
Caster is the deviation from vertical of an imaginary line drawn through the pivot points (top of strut and
lower ball joint), when viewed from the side. The caster specifications in this section will give the vehicle
the best directional stability characteristics when loaded and driven. The caster setting is not related to
tire wear. The caster setting is not adjustable.

Incorrect Thrust Angle (Dogtracking)
Item
Description
1
Vertical centerline
2
Axle centerline
3
Thrust angle
Incorrect thrust angle (also known as dogtracking) is the condition in which the rear axle is not square to
the chassis. Heavily crowned roads can give the illusion of dogtracking.
Wander
Wander is the tendency of the vehicle to require frequent, random left and right steering wheel
corrections to maintain a straight path down a level road.
Shimmy
Shimmy, as experienced by the driver, is large, consistent, rotational oscillations of the steering wheel
resulting from large, side-to-side (lateral) tire/wheel movements.
Shimmy is usually experienced near 64 km/h (40 mph), and can begin or be amplified when the tire
contacts pot holes or irregularities in the road surface.
Nibble
Sometimes confused with shimmy, nibble is a condition resulting from tire interaction with various road
surfaces and experienced by the driver as small rotational oscillations of the steering wheel. For wheel
and tire diagnosis, refer to Section 204-04 .
Poor Returnability/Sticky Steering
Poor returnability and sticky steering are used to describe the poor return of the steering wheel to center
after a turn or steering correction.
Drift/Pull
Pull is a tugging sensation felt by the hands on the steering wheel that must be overcome to keep the
vehicle going straight.
Drift describes what a vehicle with this condition does with the hands off the steering wheel.
A vehicle-related drift/pull on a flat road causes a consistent deviation from the straight-ahead
path and requires constant steering input in the opposite direction to counteract the effect.
Drift/pull may be induced by conditions external to the vehicle (wind or road crown).

Component Tests
Ball Joint Inspection
1. Prior to inspecting the ball joints for wear, inspect the wheel bearings. Install a new wheel bearing as
necessary.
2. NOTE: In order to obtain accurate measurements, the suspension must be in full rebound with the
weight of the vehicle supported by the frame.
Raise and support the vehicle by the frame to allow the wheels to hang in the rebound position.
3. Inspect the ball joint and ball joint boot for damage.
If the ball joint or ball joint boot is damaged, install a new ball joint as necessary. Refer to Section
204-01 .
4. NOTICE: Do not use any tools or equipment to move the wheel and tire assembly or suspension
components while checking for relative movement. Suspension damage may occur. The use of
tools or equipment will also create relative movement that may not exist when using hand force.
Relative movement must be measured using hand force only.
Inspect the ball joint for relative movement by alternately pulling downward and pushing upward on the
lower control arm by hand. Note any relative vertical movement between the wheel knuckle and lower
arm at the lower ball joint.
If relative movement is not felt or seen, the ball joint is OK. Do not install a new ball joint.
If relative movement is found, continue with Step 5.
5. NOTE: In order to obtain an accurate measurement, the dial indicator should be aligned as close as
possible with the vertical axis (center line) of the ball joint.
To measure ball joint deflection, attach a suitable dial indicator with a flexible arm between the lower
control arm and the wheel knuckle or ball joint stud.
6. Measure the ball joint deflection while an assistant pushes up and pulls down on the lower control arm,
by hand.
If the deflection exceeds the specification, a new ball joint must be installed. Refer to Section 20401 .
If the deflection meets the specification, no further action is required.

Front Suspension
The front suspension consists of the following components:
Lower arms
Stabilizer bar, bushings and links
Strut and spring assemblies
Wheel bearings
Wheel hubs
Wheel knuckles
Wheel studs
The front suspension utilizes a MacPherson strut system. This suspension system incorporates a strut
assembly that takes the place of the upper arm and ball joint. The strut performs the function of a shock
absorber and is encompassed by a coil spring. The strut and spring assembly carries the sprung weight
of the vehicle and is also the pivot point for the steering knuckle. This system uses a lower control arm
and ball joint for the lower (unloaded) pivot point of the steering knuckle.

DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Rear Suspension
The rear suspension consists of the following components:
Twist-beam axle (torsionally rigid axle)
Coil springs
Shock absorbers
Wheel bearing and wheel hub assemblies
Wheel studs
If compression takes place on both wheels evenly (for example when a load is placed on the vehicle),
the whole axle unit swivels evenly in the rubber-metal bearings. If only one wheel is compressed, the
cross-beam twists (undergoes torsion) and acts as a stabilizer. This minimizes track and toe changes.

Wheels And Tires
Safety Precautions
WARNING: Vehicle may have multiple drive wheels. Do not use engine to power the
driveline unless all drive wheels are elevated off the ground. Drive wheels in contact with ground
could cause unexpected vehicle movement. Failure to follow this instruction may result in
serious personal injury.
WARNING: Always match the tire size to the wheel size during assembly. Incorrect
matching can result in tire bead damage or tire separation from the wheel. Failure to follow this
instruction may result in serious personal injury to technician or vehicle occupant(s).
WARNING: Before servicing any tire, ask the customer if anyone injected a tire sealant into
the tire. Tire sealants may be flammable and can burn or explode if exposed to an ignition
source. Failure to follow this instruction may result in serious personal injury.
WARNING: Replacement wheels must be equivalent to the original equipment wheels in:
load carrying capacity.
diameter, width and offset.
pilot hole and bolt circle.
Combined load carrying capacity of replacement wheels for a given axle, must be equal to or
greater than that axle's gross axle weight rating (GAWR) identified on the vehicle's Safety
Compliance Certification label. All other specifications should be evaluated by measurement of
both the original wheel and the replacement wheel. If specifications are not equivalent, the safety
and handling of the vehicle may be degraded, which may result in serious injury to the vehicle
occupant(s).
WARNING: Never use wheels different than the original equipment. Additionally, never use
wheel nuts different than the original equipment. Failure to follow these instructions may result
in damage to the wheel or mounting system. This damage could cause the wheel to come off
while the vehicle is being driven, which could result in serious personal injury or death to vehicle
occupant(s).
WARNING: Always wear eye protection when servicing a vehicle. Failure to follow this
instruction may result in serious personal injury.
WARNING: Keep eyes away from valve stem when deflating tires. Reduce air pressure in
tire as much as possible by pushing in valve core plunger prior to removing the core. Escaping
air can carry particles that can injure the eyes. Failure to follow these instructions may result in
serious personal injury.
WARNING: Only use replacement tires that are the same size, load index, speed rating and
type (such as P-metric versus LT-metric or all-season versus all-terrain) as those originally
provided by Ford. The recommended tire and wheel size may be found on either the Safety
Compliance Certification Label or the Tire Label, which is located on the B-pillar or edge of the
driver's door. If the information is not found on these labels, consult a Ford dealer. Use of any
tire or wheel not recommended by Ford can affect the safety and performance of the vehicle,
which could result in an increased risk of loss of vehicle control, vehicle rollover, personal injury
and death. Additionally, the use of non-recommended tires and wheels could cause steering,
suspension, axle or transfer case/power transfer unit failure.
NOTICE: Do not clean aluminum wheels with steel wool, abrasive-type cleaners or strong
detergents or damage to the wheel finish may occur. Use Wheel and Tire Cleaner ZC-27-A or -B
or equivalent.
Factory-installed tires and wheels are designed to operate satisfactorily with loads up to and including
full-rated load capacity when inflated to recommended inflation pressures.
Correct tire pressure and driving techniques have an important influence on tire life. Heavy cornering,
excessively rapid acceleration and unnecessary sharp braking increase tire wear.
To equalize tire wear, rotate the tires at recommended intervals.
Tire Pressure Monitoring System (TPMS)
NOTE: The Tire Pressure Monitor (TPM) module is identified by the scan tool as the Vehicle Security
Module (VSM).
The TPMS includes:
the TPM / VSM , a stand alone receiver located in the driver's side luggage compartment (4door), or in the driver's side cargo area (5-door).
four tire pressure sensors.
TPM / VSM
The TPM / VSM contains the TPMS functionality. Refer to Tire Pressure Monitoring System in Diagnosis
and Testing for TPMS fault diagnosis and repair.
The TPM / VSM compares the information of each tire pressure sensor transmission against a pressure
limit. If the TPM / VSM determines that the tire pressure has fallen below the minimum pressure the
TPM / VSM communicates this to the Instrument Panel Cluster (IPC) on the vehicle communication
network.
Tire Pressure Monitoring System (TPMS) Pressure Sensor
The TPM / VSM uses tire pressure sensors to monitor the tire pressure in the 4 road tires. The tire
pressure sensors transmit radio frequency signals to the TPM / VSM approximately once every 60
seconds when the vehicle speed exceeds 32 km/h (20 mph).
The tire pressure sensors are battery operated and mounted on the valve stem.
Instrument Panel Cluster (IPC)
The IPC illuminates the TPMS indicator when it receives a message from the TPM / VSM .
For additional Information, refer to Section 413-01 for diagnosis and repair of the IPC .

Inspection and Verification
WARNING: Vehicle may have multiple drive wheels. Do not use engine to power the
driveline unless all drive wheels are elevated off the ground. Drive wheels in contact with ground
could cause unexpected vehicle movement. Failure to follow this instruction may result in
serious personal injury.
Verify the customer concern by carrying out a road test on a smooth road. If any vibrations are apparent,
GO to Symptom Chart - NVH .
To maximize tire performance, inspect for signs of incorrect inflation and uneven wear, which may
indicate a need for balancing, rotation or front suspension alignment.
Correct tire pressure and driving techniques have an important influence on tire life. Heavy cornering,
excessively rapid acceleration and unnecessary sharp braking increase tire wear.
Replacement tires must follow the recommended:
tire sizes.
speed rating.
load range.
tire construction type.
The use of any other tire/wheel size, load range or type can seriously affect:
ride.
handling.
speedometer/odometer calibration.
vehicle ground clearance.
tire clearance between the body and chassis.
wheel bearing life.
braking performance.
New wheels need to be installed when the vehicle wheels:
are bent.
are cracked.
are dented.
are heavily corroded.
are leaking.
have elongated wheel hub bolt holes.
have excessive lateral or radial runout.
It is mandatory to use only the tire sizes recommended on the tire label located on the driver door or
door pillar attached to the vehicle. Larger or smaller tires can damage the vehicle, affect durability and
require changing the speedometer calibration. Make sure wheel size and offsets match those
recommended for the tire in use.
1. Inspect the tires for signs of uneven wear. Refer to the following descriptions to identify the type
of wear and GO to Symptom Chart - Tire Wear for the appropriate repair action to be carried out.
2. Check the tires for:
cuts.
stone bruises.
abrasions.
blisters.
embedded objects.
3. Check the valve stems for:
cracks.
cuts.
Install a new valve stem when damage is found or anytime a new tire is installed.
4. Tread wear indicators are molded into the bottom of the tread grooves. Install a new tire when the
indicator bands become less than 2/32 inch.
Tire Wear
Tire wear is commonly defined as a loss of tread depth. Tire tread wear occurs due to friction with the
contact surface (road/pavement). The tread should wear down uniformly all the way around the
circumference of the tire and all the way across the tread face. When this does not occur, the tire may
have abnormal/incorrect wear.
Normal Tire Wear
Normal tire wear is identified as even wear around and across the tread. Because there are many
factors (driving style, road surfaces, type of vehicle, type of tire) that can affect tire wear, there is no
absolute mileage expectation for a normal wear condition. A tire is considered worn-out when the tread
has worn to the level of the tread-wear indicators.
Abnormal/Incorrect Tire Wear
Abnormal/incorrect tire wear is identified as tire wear that is not even around or across the tread and that
creates performance-related issues.
Abnormal/incorrect wear can be caused by numerous factors, some of which include driving style
(aggressive, passive), climate (hot, cold), road conditions, vehicle loading and maintenance (correct tire
pressure, rotation intervals and balance). It is important to determine the root cause of wear on a vehicle
before carrying out repair. Tires exhibiting abnormal/incorrect tire wear may still be serviceable provided
that the minimum tread depth is greater than 2/32 inch and the tire is not causing a vehicle performance
(noise/vibration) concern.
Some abnormal/incorrect wear patterns look the same all the way around the tread of the tire, other
wear patterns are not consistent and can occur in various spots on the tread area. The underlying
causes of the 6 wear categories are different. Refer to the following descriptions to identify the type of
wear and GO to Symptom Chart - Tire Wear for the appropriate repair action to be carried out.
Inner Edge/Shoulder Wear
Inner edge (or shoulder) wear occurs on the inside edge of the tire and is usually caused by excessive
toe out and/or excessive negative camber. If the tread depth of the outer shoulder is at least 50%
greater than the tread depth of the inner shoulder, the tire is experiencing inner edge/shoulder wear. To
determine whether tires have this type of wear, visually inspect the tires. In some instances, it may be
necessary to measure the tread depth of each rib and compare it to that of the shoulder.
NOTE: RF tire shown, others similar.
Outer Edge/Shoulder Wear
Outer edge (or shoulder) wear occurs on the outside edge of the tire and is usually caused by excessive
toe in and/or excessive positive camber. If the tread depth of the inner shoulder is at least 50% greater
than the tread depth of the outer shoulder, the tire is experiencing outer edge/shoulder wear. To
determine whether tires have this type of wear, visually inspect the tires. In some instances, it may be
necessary to measure the tread depth of each rib and compare it to that of the shoulder.
NOTE: RF tire shown, others similar.
Heel/Toe Wear
Heel/toe wear (also known as feathering) occurs along the outside or inside edge/shoulder of the tire. To
determine whether tires have this type of wear, visually inspect the tires in both the inside and outside
shoulder ribs. In some instances, it may be necessary to measure the difference in tread depth of
leading versus trailing edge of each lug in the inside and outside shoulder rib.
Diagonal Wear
Diagonal wear occurs diagonally across the tread area and around the circumference of the tire. To
determine whether tires have this type of wear, visually inspect the tires to determine if the wear pattern
runs diagonally across the tread and around the circumference of the tire. In some instances, the
difference in tread depth along the diagonal wear pattern may need to be measured.

Component Tests
Radial Runout
Radial runout is the egg-shaped deviation from a perfect circle and is measured perpendicular to the
circumference. On a wheel and tire assembly, this means measuring the center tire tread rib. The center
rib is indicative of the condition of the tire as a whole. Total runout is the difference between the
maximum-to-minimum gauge reading. The high spot is the location of maximum runout.

Loaded Runout Measurement (Hunter Road Force® 9700 Series Wheel Balancer)
NOTE: Diagnosis of tire/wheel vibration should not be performed on tires with less than 320 km (200
mi). Some initial tire/wheel vibration issues (such as flat spotting) may correct themselves after the tires
have been in service for 320 km (200 mi).
This procedure is intended to assist with the diagnosis of wheel and tire assembly runout and/or force
variation issues.
The Hunter Road Force® 9700 Series Wheel Balancer measures the wheel and tire assembly's loaded
runout and the tire's radial spring rate. The balancer then converts the runout into pounds of force
(termed as Road Force®). Measuring loaded runout (Road Force®) is more effective than measuring
unloaded runout using a dial indicator.
1. Using a tire crayon, record the vehicle position on the inward sidewall of all 4 tires.
2. Remove the wheel and tire assemblies. Refer to Wheel and Tire in this section.
3. NOTE: Use only the Digital Tire Gauge any time tire pressures are measured to be sure that
accurate values are obtained.
Make sure that the tire pressures are set to the correct pressure as indicated on the Vehicle
Certification (VC) label.
4. NOTICE: Make sure that the correct wheel balancer adapters are used when mounting the
assembly to the wheel balancer or damage to the wheel may occur.
NOTE: Make sure that the wheel and tire assembly is clean and free of foreign material prior to
installation on the balancer.
NOTE: The wheel balancer inflation station must be turned OFF for tires with inflation pressures
of 414 kPa (60 psi) or above.
Mount the wheel and tire assembly on a suitable wheel balancer using the correct wheel balancer
adapters as shown. Refer to the list of recommended wheel balancer adapters on the PTS
website.

5. Measure the Road Force®.
Temporarily mark the high spot and the Road Force® value on the sidewall of the tire. If
the wheel and tire assembly Road Force® value is greater than 9 kg (20 lb), carry out the
Match Mounting procedure to optimize the wheel and tire assembly.
If the wheel and tire assembly Road Force® value is 9 kg (20 lb) or less, permanently mark
the high spot and the Road Force® value on the inward sidewall of the tire for reference
during future wheel and tire service. Balance the assembly and install the wheel and tire on
the vehicle using the Wheel-to-Hub Optimization procedure.
Runout Measurement (Dial Indicator)
NOTE: Diagnosis of tire/wheel vibration should not be performed on tires with less than 320 km (200
mi). Some initial tire/wheel vibration issues (such as flat spotting) will correct themselves after the tires
have been in service for 320 km (200 mi).
NOTE: Loaded run-out measurements are the preferred method for verifying tire serviceability. While a
dial indicator can be used to optimize the position of the tire on the wheel, the unloaded run-out
measurement cannot accurately determine if the tire should be removed from service.
The following procedures should be used if normal diagnostics leads to a potential runout issue.
Some vehicles may exhibit a wheel and tire vibration caused by excessive runout. Radial runout
measurements can be taken using a dial indicator and should be measured with the wheel and tire
assembly mounted on a suitable wheel balancer. The dial indicator should be mounted securely to
eliminate gauge movement when measuring runout.
1. NOTE: Use only the Digital Tire Gauge any time tire pressures are measured to be sure that
accurate values are obtained.
Make sure that the tire pressures are set to the correct pressure as indicated on the VC label.
2. Using a tire crayon, record the vehicle position on the inward sidewall of all 4 tires.
3. Remove the wheel and tire assemblies. Refer to Wheel and Tire in this section.
4. NOTICE: Make sure that the correct wheel balancer adapters are used when mounting the
assembly to the wheel balancer or damage to the wheel may occur.
NOTE: Make sure that the wheel and tire assembly is clean and free of foreign material prior to
installation on the balancer.
Mount the wheel and tire assembly on a suitable wheel balancer using the correct wheel balancer
adapters as shown. Refer to the list of recommended wheel balancer adapters on the PTS
website.

5. NOTE: Masking tape can be applied on the center tread rib to allow for a smoother measuring
surface. Some fluctuation of the gauge reading is expected. Observe the overall sweep of the
gauge from the highest to the lowest spot on the tire.
Position a suitable dial indicator and stand with the dial indicator on the center tread rib.
Rotate the wheel and tire assembly (or wheel) to locate the low spot.
Adjust the runout gauge to read 0.
Rotate the wheel and tire assembly one complete revolution to make sure that the low spot
has been found and that the dial indicator returns to a 0 reading.
6. While slowly and constantly rotating the wheel and tire assembly (or wheel), measure the radial
runout.
Note the variance (runout) from 0 on the dial of the gauge.
If the runout reading of a wheel and tire assembly is greater than 1.14 mm (0.045 in),
locate and temporarily mark the high spot and runout reading on the sidewall of the tire
and carry out the Match Mounting procedure to optimize the wheel and tire assembly.
If the runout reading of a wheel and tire assembly is 1.14 mm (0.045 in) or less,
permanently mark the high spot and the runout reading on the inward sidewall of the tire
for reference during future wheel and tire service. Balance the assembly and install the
wheel and tire on the vehicle using the Wheel-to-Hub Optimization procedure.
Match Mounting
NOTE: Road Force® values in illustrations are shown in pounds.
Match mounting is a technique used to reduce radial runout or road force on wheel and tire assemblies.
Excessive runout is a source of ride quality complaints and match mounting can be used to minimize the
runout. Match mounting can be accomplished by changing the position of the tire on the wheel.
1. Position the wheel and tire assembly on a tire machine and put a reference mark on the tire
sidewall at the valve stem position.

2. NOTICE: For vehicles equipped with a Tire Pressure Monitoring System (TPMS), the
sensor may be damaged by incorrect tire mounting or dismounting. Dismount the tire from
the wheel as instructed in the Disassembly and Assembly procedure. Failure to follow
these instructions may result in TPMS component damage.
NOTE: Always make sure that the final high spot and measurement values are permanently
marked on the inward sidewall of the tire for reference during future wheel and tire service.
Using a suitable tire machine, separate the tire beads from the wheel.
Lubricate the tire beads using a suitable fast drying, corrosion inhibiting tire bead lubricant.
Position the tire 180 degrees (half-way around) on the rim so the valve stem reference
mark is now opposite the valve stem.
3. Re-inflate the wheel and tire assembly to the specified air pressure and measure the assembly
again using a suitable dial indicator or Hunter Road Force® 9700 Series Wheel Balancer. Mark
the second high spot on the tire.
If the runout or Road Force® is reduced to within specifications, the concern has been
resolved. Balance the assembly and install on the vehicle using the Wheel-to-Hub
Optimization procedure.
4. If the second runout or Road Force® measurement is still not within specification and both high
spots are close to each other (within 101.6 mm [4 in]), the root cause is probably the tire (the high
spot followed the tire).
To be SURE that the tire is causing the high runout, it is necessary to have 2 runout or
Road Force® measurements that are not within specification and the high spots must be in
approximately the same location on the tire's sidewall. If the tire is the cause, install a new
tire, balance the assembly and install on the vehicle using the Wheel-to-Hub Optimization
procedure.
If the second high spot is not within 101.6 mm (4 in) of the first high spot, proceed to the
next step.

5. If the second high spot is still above specification and is within 101.6 mm (4 in) of being opposite
the first high spot on the wheel, the root cause is probably the wheel (the high spot followed the
wheel). Dismount the tire from the wheel, mount the wheel on a balancer and check the wheel
runout. If the wheel runout exceeds 1.14 mm (0.045 in), install a new wheel, balance the
assembly and install on the vehicle using the Wheel-to-Hub Optimization procedure.

6. NOTE: If the second high spot did not follow the wheel or the tire and the runout is still not within
specification, improvements may be made by rotating the tire 90 degrees (one-fourth turn).
Draw an arrow on the tire sidewall from the second high spot towards the first high spot (in the
shortest direction).
Separate the tire beads from the wheel and rotate the tire 90 degrees (one-fourth turn) in
the direction of the arrow.

Wheel-to-Hub Optimization
Wheel-to-hub optimization is important. Clearance between the wheel and hub can be used to offset or
neutralize the Road Force® or run-out of the wheel and tire assembly. For every 0.001 inch of wheel-tohub clearance, the Road Force® can be affected between 1 and 3 pounds depending on the tire
stiffness.
NOTE: The example below illustrates how the clearance between the wheel and the hub can be used to
offset the high spot of radial run-out or Road Force®. Following the procedure will make sure of the best
optimization.
1. Position the wheel and tire assembly on the vehicle so that the high spot location of radial run-out
or Road Force® is at the 6 o'clock position and install the wheel nuts by hand until snug.
2. NOTE: Do not allow the full weight of the vehicle to rest on the tires while tightening the wheel
nuts.
Lower the vehicle until the tires make contact with the ground, slightly loading the suspension.
Tighten the wheel nuts as described in Wheel and Tire in this section.

Principles of Operation
WARNING: The tire pressure monitoring system (TPMS) sensor battery may release hazardous
chemicals if exposed to extreme mechanical damage. If these chemicals contact the skin or eyes, flush
immediately with water for a minimum of 15 minutes and get prompt medical attention. If any part of the
battery is swallowed, contact a physician immediately. When disposing of TPMS sensors, follow the
correct procedures for hazardous material disposal. Failure to follow these instructions may result in
serious personal injury.
NOTE: The Tire Pressure Monitor (TPM) module is identified by the scan tool as the Vehicle Security Module
(VSM).
The Tire Pressure Monitoring System (TPMS) uses tire pressure sensors located in the wheels to monitor the
tire pressure of all 4 tires (there is no sensor in the spare tire). Each sensor has a unique identifier that is
transmitted to the TPMS receiver during system training. The TPM / VSM retains these identifiers in memory
and associates them with a vehicle position based on the training order. The sensors transmit tire pressure
information to the TPM / VSM via radio frequency signals once every 60 seconds when vehicle speed exceeds
32 km/h (20 mph), or once every 6 hours when stationary. The TPM / VSM function compares tire pressure
information against a low-pressure limit. If it determines the tire pressure has fallen below this limit, the TPM /
VSM sends a message requesting illumination of the TPMS indicator to the Instrument Panel Cluster (IPC) over
the Medium Speed Controller Area Network (MS-CAN) bus. The IPC illuminates the TPMS indicator when
commanded by the TPM / VSM .
Radio Frequency Interference (RFI) can create intermittent TPMS issues that are difficult to diagnose. RFI can
be caused by the addition of aftermarket equipment that blocks the TPMS sensor transmissions from getting to
the Tire Pressure Monitor (TPM)/Vehicle Security Module (VSM). Devices causing RFI can prevent the module
from communicating with any of the 4 tire pressure sensors.
Tire Pressure Monitoring System (TPMS) Indicator
The TPMS indicator may display faults that cannot be resolved by the customer. Treat these messages as
TPMS DTCs or symptoms that must be serviced.
Tire Pressure Monitoring System (TPMS) Indicator Is On Continuously from Key ON.
The TPMS indicator is illuminated continuously when the ignition is turned to the ON position and any of the tire
pressures are low. A DTC is not present for this condition and the TPMS status PID: TP_STAT equals LOW.
When this condition exists, the tire pressure must be adjusted in all tires to the recommended cold pressure as
noted on the Vehicle Certification (VC) label. GO to Symptom Chart .
Ambient Temperature Change and Tire Pressure
NOTICE: Do not inflate tires more than maximum tire pressure stamped on the tire sidewall. Premature
tire wear or damage to the tire may result.
Tire pressures fluctuate with temperature changes. For this reason, set tire pressures to specification when
tires are at outdoor ambient temperatures. If the vehicle is allowed to warm up to shop temperatures, and the
outside temperature is less than shop temperature, adjust the tire inflation pressure accordingly.
If the tires are inflated to specification at shop temperatures and the vehicle is moved outdoors when the
outdoor ambient temperature is significantly lower, the tire pressure may drop enough to be detected by the
TPMS and illuminate the TPMS indicator.
As the ambient temperature decreases by 6°C (10°F), tire pressure decreases 7 kPa (1 psi). Adjust the tire
pressure by 7 kPa (1 psi) for each 6°C (10°F) ambient temperature drop as necessary to maintain tire pressure
as specified on the Vehicle Certification (VC) label. Refer to the following tables to adjust the tire pressure
indoors for colder outside temperatures.
Tire Pressure Monitoring System (TPMS) Indicator Flashes For 70 seconds From Key ON And Then
Remains On Continuously
The TPMS indicator flashes for 70 seconds and then remains on continuously if the TPMS is malfunctioning.
The TP_STAT PID can be used to determine why the TPMS indicator is flashing.
Tire Pressure Monitoring System (TPMS) PID Definitions
TPM / VSM Status PID
The TPM / VSM monitors the TPMS status. The TPMS status can be monitored using the scan tool PID
TP_STAT. The PID has 4 valid states:
1. TP_STAT = SENSOR FAULT.
SENSOR FAULT is displayed if the TPM / VSM has not heard from 1 to 3 TPMS sensors for 20
minutes when the vehicle speed is above 32 km/h (20 mph).
2. TP_STAT = SYSTEM FAULT.
SYSTEM FAULT is displayed if the TPM / VSM does not receive a signal transmission from all 4
TPMS sensors for 20 minutes and the vehicle speed is above 32 km/h (20 mph).
3. TP_STAT = LOW.
LOW is displayed if the TPM / VSM has detected that at least 1 TPMS sensor is reporting low tire
pressure.
4. TP_STAT = ACTIVE.
ACTIVE is displayed if the TPMS is functioning normally.
TPMS Last Warning Event PID Definitions
The TPMS uses the TPMS last warning event PIDs to store detailed information about the last 5 times the
TPMS indicator was illuminated. These PIDs can be used to acquire more information about a particular TPMS
event.
EVT1_IGN through EVT5_IGN
The number of key cycles since the TPMS indicator was illuminated. This PID cycles from zero to 255 and then
starts over from zero again. Use this PID to determine how long ago a TPMS event occurred and the time (in
key cycles) between events.
EVT1_TLOC through EVT5_TLOC
This is the last programmed location for the sensor causing each TPMS event. Due to tire rotation, the sensor
may no longer be at the location indicated. It is suggested that all the PIDs be recorded, the system retrained,
and the sensor identifier PIDs be used to pinpoint the actual location of each sensor.
EVT1_PSI through EVT5_PSI
This is the tire pressure associated with each TPMS indicator event. This can be used to identify the TPMS
events that were due to low pressure and to determine when a sensor is transmitting inaccurate tire pressure.
EVT1_STAT through EVT5_STAT
Describes the warning status of each TPMS event by using the information received from the TPMS status
(TP_STAT) PID. If there is a communication issue, the status could be NORMAL.
UNKNOWN
NORMAL (normal operation)
LOW (low pressure event)
FAULT (sensor fault or system fault)
EVT1_TxID through EVT5_TxID
This is the unique identifier of the sensor involved in each TPMS event. EVT1 is the most recent event that
triggered the TPMS indicator.
Wheel Rotation and Sensor Training Techniques
Moving a Problem Sensor/Wheel to a Different Position
If a sensor in a certain location has caused several events, yet the sensor trains and seems to operate
normally, moving that particular sensor/wheel to a different location on the vehicle can isolate the issue to a
certain sensor/wheel location. Carry out a road test following sensor/wheel relocation to attempt to recreate the
fault. This determines whether the fault followed the sensor or remained in the original sensor location.
Training Sensors in a Different Order
This is a technique to get past a left front sensor that may not be responding to determine if the remaining
sensors train to the module. This can help save time determining if other sensors are having issues or if the
module is experiencing training difficulties with a certain location.
NOTE: Training known good sensors from another vehicle cannot differentiate between a faulted module and
RFI .
Training Known Good Sensors From Another Vehicle
Use this technique to differentiate between a sensor fault and a module fault. If neither the originally installed
sensors nor the known good sensors can be trained, then a module fault or RFI concern is present. See items
that cause RFI , below. Do not replace the original sensors.
Items That Cause RFI
Non-OEM Equipment
The following equipment has been found to cause RFI :
Video equipment has been found to cause RFI especially when the video and power supply lines are
near the TPMS .
Car alarms (even those installed by dealerships) can create enough RFI to cause the TPMS to
malfunction or lose considerable range. These car alarms can sometimes be difficult to locate, as they
are usually hidden somewhere out of the way.
Many different in-vehicle cell phone chargers have been found to cause considerable RFI . The vehicles
with the power point closest to the TPM / VSM are the most affected. It must be noted that most cell
phone chargers do not produce high levels of RFI all of the time. This depends on the state of charge of
the cell phone battery. The phone must be almost completely discharged in some cases.
Power supplies and DC/AC inverters typically create significant RFI . Most consumer grade equipment
has very little filtering or shielding.
OEM Modules
In some cases, the RFI may actually be caused by a module or ground on the vehicle. A poor ground or loose
ground shield can disable the system. Modules that have microcontrollers using clock circuits to create the
timing pulses for the microprocessor may radiate RFI .
Using Customer's Electronics to Pinpoint the Radio Frequency Interference (RFI) Source
This can be a way to determine the cause of an issue well before the sensors and module are replaced with
little or no affect on the system performance. Since this takes more up-front work, it relies on working with the
customer to determine what equipment was being used at the time of the event.
Options for Eliminating Intermittent TPMS Conditions Caused by RFI
If an OEM component or customer device is causing an RFI issue, the device can be replaced.
If a phone charger is causing an RFI issue, the customer should consult with their cell phone provider to
acquire a different phone charger.
If a device such as an dealer-installed alarm is causing an RFI issue, the device could be moved to
another location on the vehicle. In the case of a portable device, the power cord could be moved to
another power point location.
In summary, if the RFI source is present and cannot be moved or replaced, the intermittent issue remains. The
TPMS system must accept RFI and the unwanted system operation it can cause.
Inspection and Verification
1. Keep the following items in mind when diagnosing any TPMS related issue:
The tire pressure sensors are not designed to be used with aftermarket wheels. The use of runflat tires (tires with steel body cord plies in the tire sidewall) that are not originally equipped, may
block the TPMS signal and are not recommended.
Non-OEM modifications made to the vehicle may result in false TPMS warnings.
Swapping wheels on vehicles with the same TPMS sensors sets a fault if the sensors are not
trained. Refer to Tire Pressure Monitoring System (TPMS) Sensor Training in this section.
The tire pressure calibrations in the TPM / VSM for the system cannot be changed to use lower
tire pressures than those listed on the Vehicle Certification (VC) label.
Certain non-OEM electronic equipment may cause RFI and false TPMS warnings. To aid in
diagnosis, obtain information from the owner regarding any equipment that has been added or
was in use at the time the TPMS fault occurred.
It may be necessary to disconnect any electronic add-on equipment to verify its impact on TPMS
operation. For intermittent cases, it may be necessary to ask the customer to provide portable
electronic equipment to verify its impact on the system.
2. Visually inspect for obvious signs of mechanical or electrical damage.

Pinpoint Test E: DTCs B106E, B106F, B1217 and B1218
Refer to Wiring Diagrams Cell 118 , Tire Pressure Monitoring System (TPMS) for schematic and connector
information.
Normal Operation
The Tire Pressure Monitoring System (TPMS) uses the horn as a feedback signal during TPMS sensor training
and activation by sending a ground signal to the Body Control Module (BCM). When the BCM receives this
ground signal it activates the horn relay and sounds the horn.
The TPMS monitors the circuit for shorts to voltage, ground and opens. If one of these conditions is detected,
the appropriate DTC sets.
The TPM / VSM utilizes a Field-Effect Transistor (FET) (in place of a fuse) to protect itself during a short circuit
condition, the FET is also known as a solid state driver. The FET is only designed to withstand a certain amount
of use.
The TPMS keeps track of how many times DTC B106E is set and once that counter reaches a predetermined
number (based off of FET durability) DTC B106F (and usually B1342) set. DTCs B1217, B1218 and/or B106E
also set along with B106F. The only way to clear B106F is by installing a new Tire Pressure Monitor
(TPM)/Vehicle Security Module (VSM). Repair the circuit conditions that set DTCs B1217, B1218 and/or B106E
before installing a new TPM / VSM .
DTC Description

Pinpoint Test I: TPMS Indicator On Continuously From Key ON With No Related DTCs Present
Normal Operation
The TPMS function compares each tire pressure sensor transmission against a low pressure limit. If the
pressure falls below this limit, the Tire Pressure Monitor (TPM)/Vehicle Security Module (VSM) communicates
this on the Medium Speed Controller Area Network (MS-CAN) to the Instrument Panel Cluster (IPC). The IPC
illuminates the TPMS indicator.
This pinpoint test is intended to diagnose the following:
Low tire pressure
Spare tire in use
Stuck TPMS sensor

NOTE: If the vehicle has been stationary for more than 30 minutes, the sensors will go into a "sleep
mode" to conserve battery power. It will be necessary to wake them up so they will transmit the latest tire
pressure information to the Tire Pressure Monitor (TPM)Vehicle Security Module (VSM). For additional
information, refer to Tire Pressure Monitoring System (TPMS) Sensor Activation in this section.
NOTE: The TPMS Sensor Training procedure must be done on a single vehicle, in an area without
Radio Frequency Interference (RFI) and at least 1 m (3 ft) away from other vehicles equipped with
TPMS .
RFI is generated by certain electrical motors and appliance operation, cellular telephone chargers,
remote transmitters, power inverters and portable entertainment equipment.
NOTE: The TPM / VSM has a 2-minute time limit between sensor responses. If the TPM / VSM does not
recognize any 1 of the 4 tire pressure sensors during this time limit, the horn will sound twice and the
entire procedure must be repeated.
NOTE: For vehicles with different front and rear tire pressures the tire pressure sensors must be trained
following a tire rotation. Failure to train the sensors will cause the TPMS indicator to illuminate.
1. NOTE:
An animated version of this procedure is available on-line.
Turn the ignition switch to the OFF position, then press and release the brake pedal.
2. Cycle the ignition switch from the OFF position to the RUN position 3 times, ending in the RUN
position.
3. Press and release the brake pedal.
4. Turn the ignition switch to the OFF position.
5. Turn the ignition switch from the OFF position to the RUN position 3 times, ending in the RUN
position.
The horn will sound once and the TPMS indicator will flash if the training mode has been
entered successfully.
6. NOTE: It may take up to 6 seconds to activate a tire pressure sensor. During this time, the Tire
Pressure Monitor Activation Tool must remain in place at the valve stem.
NOTE: If a sensor does not respond to the Tire Pressure Monitor Activation Tool, move the
vehicle to rotate the wheels at least one-fourth of a turn and attempt to activate the same sensor
again. If the sensor still does not respond, attempt to activate the same sensor again using the
customer activation tool (if available). If the sensor still fails to train, attempt to train the sensor
with the vehicle doors open.
Place the Tire Pressure Monitor Activation Tool on the LF tire sidewall at the valve stem. Press
and release the test button on the Tire Pressure Monitor Activation Tool. The horn will sound
briefly to indicate that the tire pressure sensor has been recognized by the TPM / VSM .
An
animated version of this procedure is available on-line.
7. Within 2 minutes of the horn sounding, place the Tire Pressure Monitor Activation Tool on the RF
tire sidewall at the valve stem and press and release the test button to train the RF tire pressure
sensor.
8. NOTE: Do not wait more than 2 minutes between training each sensor or the TPM / VSM will time
out and the entire procedure must be repeated.
Repeat Step 7 for the RR and LR tires.
The procedure is completed after the last tire has been trained.
Successful completion of the training procedure will be verified by turning the ignition switch to the
OFF position without the horn sounding. If the horn sounds twice when the switch is turned to the
OFF position, the training procedure was not successful.
9. Using the scan tool, locate the updated TPMS sensor identifiers trained to the TPM / VSM and
document them on the applicable warranty claim.
10. NOTE: This step is required to clear DTC C2780, cause the TPM / VSM to exit the manufacturing
mode and to make sure there are no other concerns with a newly programmed TPM / VSM .
If the sensors are being trained due to the installation of a new TPM / VSM , clear any DTCs and
carry out the TPM / VSM On-Demand Self Test.

SECTION 205-00: Driveline System — General Information
DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Driveline System
The driveline system consists of the following:
Right halfshaft with inner and outer CV joint
Left halfshaft with inner and outer CV joint
Intermediate shaft connecting the transaxle to the right halfshaft
Intermediate shaft bearing that supports the inner right halfshaft CV joint
Circlips that retain the intermediate shaft and left halfshaft inner CV joint in the transaxle
differential side gears
Splined outer CV joints that mesh with the front drive hubs
Outboard CV joint wheel hub nuts that secure the CV joints to the wheel hubs
The transaxle contains the differential assembly. The differential receives torque directly from the
transmission. Inside the differential, side gears are splined to the right inboard CV joint and intermediate
shaft. The differential allows the halfshaft and intermediate shaft to be driven at different speeds as
required, such as when cornering. The rotational direction of the halfshafts determines the vehicle
movement. The articulation of the front wheels, both in steering and normal jounce and rebound, is
controlled by the CV joint. Both plunge and multi-ball style CV joints are used. The CV joints are
permanently lubricated with a special high temperature grease and require no periodic maintenance.
Halfshaft Handling
NOTICE: Excessive pulling force on the interconnecting shaft between the joints of the halfshaft
will result in internal joint damage and separation. Axial loads used in assisting removal should
be applied through the inboard joint housing only. Handle the halfshaft only by the
interconnecting shaft to avoid pull-apart and potential damage to the Constant Velocity (CV)
joints. Do not over-angle the CV joints. Damage will occur to an assembled inner CV joint if it is
over-plunged outward from the joint housing.
NOTE: Never use the halfshaft assembly as a lever to position other components. Always support the
free-end of the halfshaft. Do not allow the boots to contact sharp edges or hot exhaust components.
Handle all halfshaft components carefully during removal and installation procedures.

DIAGNOSIS AND TESTING
2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Driveline System
Principals of Operation
Driveline System — General Information
The driveline system enables the power generated by the engine and transferred through the transaxle
to place the vehicle in motion. Rotational torque received from the transaxle is delivered to the front
wheels by halfshafts. The CV joints at the ends of the shafts allow the shafts to rotate smoothly in an
allowable angle plane. The rotational torque is introduced into the differential ring gear which drives the
differential. The differential divides the torque between the left and right axle shafts, while permitting the
shafts to turn at different speeds when required, such as when cornering.
Inspection and Verification
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical damage.
Visual Inspection Chart
Mechanical
CV joints, housings, boots and clamps
Intermediate shaft support bearing
Intermediate shaft support bracket
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible)
before proceeding to the next step.
4. If the cause is not visually evident, verify the symptom and GO to Symptom Chart - NVH .
Intermediate Shaft Support Bearing
With the vehicle in NEUTRAL, position it on a hoist. Refer to Section 100-02 . Rotate the intermediate
shaft by hand. If the support bearing shows any signs of roughness or wear, install a new intermediate
shaft bearing. Refer to Section 205-04 .
Symptom Chart — NVH
Symptom Chart — NVH
NOTE: NVH symptoms should be identified using the diagnostic tools that are
available. For a list of these tools, an explanation of their uses and a glossary of
common terms, refer to Section 100-04 . Since it is possible any one of multiple
systems may be the cause of a symptom, it may be necessary to use a process of
elimination type of diagnostic approach to pinpoint the responsible system. If this is
not the causal system for the symptom, refer back to Section 100-04 for the next likely
system and continue diagnosis.

SECTION 205-04: Front Drive Halfshafts
DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Front Drive Halfshafts
The front halfshafts consist of the following:
CV joints at both ends to make sure that the rotation is smooth
Tripod CV joints (with tripod, running rollers and tripod housing) are fitted on the transmission side
CV joints nearest the wheel are caged ball joints (with ball star, ball cage and ball shell)
LH tripod joint is secured in the differential with a circlip
Intermediate shaft (RH side) is secured in the differential by the intermediate shaft bearing
Tripod housing of the tripod CV joint for the RH front halfshaft and the intermediate shaft are
attached as a unique part
Outboard CV joints are attached to the splined wheel hubs with nuts that control wheel bearing
preload
The front halfshafts transmit torque generated by the engine from the transaxle to the wheels. In order to
allow vertical and horizontal movement of the wheels, the front drive halfshafts operate at varying
lengths and angles. The tripod CV joints allow for changes in halfshaft length during axial movements.
The caged balls of the outer CV joint permit the articulation of the front wheels and retain the stability of
the intermediate and interconnecting shafts.
Special care should be taken when removing and installing or assembling and disassembling front
halfshafts. The inner tripod joint must not be bent at more than 18 degrees. Do not allow the boots to
come into contact with sharp edges or the hot exhaust system. Do not drop the front halfshaft as this can
damage the inside of the boots without any signs of damage showing on the outside. Do not use front
halfshafts as levering tools for the installation of other components. The front halfshafts must always be
supported when disconnected from the wheel ends.

Principles of Operation
Brake System
Applying the brake pedal uses lever action to push a rod into the brake booster which, through the use of
vacuum, boosts the force of the rod and then transmits this force into the master cylinder. This produces
hydraulic pressure in the master cylinder. On vehicles not equipped with ABS, the hydraulic pressure is
transmitted by brake fluid through the brake tubes to the individual brake calipers. On vehicles equipped with
ABS, the hydraulic pressure is transmitted by brake fluid through the brake tubes to the ABS Hydraulic Control
Unit (HCU), which then distributes that pressure through brake tubes to the individual brake calipers. The brake
calipers use hydraulic pressure to apply the pads. The application of the brake pads will cause the rotation of the
wheels to slow or stop, depending on how much brake pressure is applied. The parking brakes carry out the
same function except that they are mechanically actuated by a cable that connects only to the rear brakes.
Brake Master Cylinder Compensator Ports
The purpose of the compensator ports in the brake master cylinder is to supply additional brake fluid from the
master cylinder reservoir when needed by the brake system due to brake lining wear and allow brake fluid to
return to the master cylinder reservoir when the brakes are released. The returning brake fluid creates a slight
turbulence in the master cylinder reservoir. This is a normal condition and indicates that the compensator ports
are not clogged. Clogged compensator ports may cause the brakes to hang up or not fully release.
Red Brake Warning Indicator
The red brake warning indicator alerts the driver to certain conditions that exist in the brake system. The
Instrument Cluster (IC) performs a bulb check when the ignition key is turned to the RUN position. The
conditions that cause the indicator to illuminate are low brake fluid level, the parking brake is applied or there is a
fault in the ABS (if the yellow ABS warning indicator is also illuminated). To diagnose red brake warning indicator
concerns, refer to Section 413-01 .

WARNING: Do not use any fluid other than clean brake fluid meeting manufacturer's
specification. Additionally, do not use brake fluid that has been previously drained. Following
these instructions will help prevent system contamination, brake component damage and the
risk of serious personal injury.
WARNING: Carefully read cautionary information on product label. For EMERGENCY
MEDICAL INFORMATION seek medical advice. In the USA or Canada on Ford/Motorcraft
products call: 1-800-959-3673. For additional information, consult the product Material Safety
Data Sheet (MSDS) if available. Failure to follow these instructions may result in serious personal
injury.
NOTICE: Blistering or swelling of rubber brake components can indicate contamination of the
brake fluid by a petroleum-based substance. The entire hydraulic brake system must be flushed
with clean, specified brake fluid and contaminated rubber components must be replaced to
prevent recontamination.
NOTICE: Do not spill brake fluid on painted or plastic surfaces or damage to the surface may
occur. If brake fluid is spilled onto a painted or plastic surface, immediately wash the surface
with water.
The first indication that something may be wrong in the brake system is a change in the feel through the
brake pedal. The brake warning indicator in the Instrument Cluster (IC) and the brake fluid level in the
brake master cylinder reservoir are also indicators of system concerns.
If a wheel is locked and the vehicle must be moved, open a bleeder screw at the locked wheel to let out
enough fluid to relieve the pressure. Close the bleeder screw. If multiple wheels are locked, check the
brake pedal free play to verify brake pedal is not partially applied. These operations may release the
brakes, but will not correct the concern. If this does not relieve the locked wheel condition, repair the
locked components before proceeding.
1. Verify the customer concern.
For parking brake concerns, refer to Section 206-05 .
For ABS concerns, refer to Section 206-09 .

Component Tests
Brake Booster
1. Disconnect the check valve from the brake booster and connect a suitable vacuum/pressure
tester to the booster side of the check valve.
2. Apply the parking brake, start the engine and place the transmission in NEUTRAL.
Allow the engine to reach normal operating temperature.
3. NOTE: Subtract approximately 4.0193 kPa (1 in-Hg) from the specified reading for every 304.8 m
(1,000 ft) of elevation above sea level.
Verify that vacuum is available at the check valve with engine running at normal idle speed.
The vacuum gauge should read between 51-74 kPa (15-22 in-Hg).
If specified vacuum is available, stop the engine, connect the check valve and continue
with Step 5.
If specified vacuum is not available, continue with Step 4.
4. Disconnect the check valve from the vacuum hose and verify that the specified vacuum is
available at the hose with the engine at idle speed and the transmission in NEUTRAL.
If specified vacuum is available, stop the engine, install a new check valve and continue
with Step 5.
If specified vacuum is not available, stop the engine, connect the vacuum hose to the
check valve and refer to Section 303-00 to diagnose the no/low vacuum condition.
5. Apply the brake pedal several times to exhaust all vacuum from the system.
6. Apply the brake pedal and hold it in the applied position. Start the engine and verify that the brake
pedal moves downward after the engine starts.
If the brake pedal moves, the brake booster is operating correctly.
If the brake pedal does not move, install a new brake booster. Refer to Section 206-07 .
7. Operate the engine a minimum of 20 seconds at idle. Stop the engine and let the vehicle stand for
10 minutes, then apply the brake pedal. The brake pedal feel should be the same as that noted
with the engine operating.
If the brake pedal feels hard (no power assist), install a new brake booster check valve and
retest.
If condition still exists, install a new brake booster. Refer to Section 206-07 .
If the brake pedal feels the same as noted with the engine operating, the check valve is
functioning properly.
Brake Master Cylinder — Bypass Condition
1. Inspect the master cylinder. Refer to Brake System Inspection in this section.
2. Disconnect the brake tubes from the master cylinder.
3. Plug the outlet ports of the master cylinder.
4. NOTE: Make sure that the outlet port plugs do not show signs of leakage.
Lightly apply the brakes and hold for 10 seconds. Release the brakes and then reapply with
heavy force. If brake pedal height cannot be maintained, the brake master cylinder has an internal
leak and a new brake master cylinder must be installed.
If brake pedal height is maintained, reinstall brake tubes and tighten to specifications.
Refer to Specifications in this section. After installation, bleed the brake system. Refer to
Brake System Bleeding in this section.
Brake Master Cylinder — Compensator Port
1. Inspect the master cylinder. Refer to Brake System Inspection in this section.

hardware as necessary.
Verify that the backing plate contact points are free of corrosion that may cause binding.
Clean or install new as necessary.
Verify correct brake shoe adjustment.
For additional information, refer to Section 206-02 .
Brake Discs
NOTICE: Using an impact tool without a torque socket will lead to unevenly tightened wheel nuts.
This causes brake disc on-vehicle lateral runout and brake roughness.
NOTE: It is generally not required to install new brake discs to address noise issues.
1. Inspect the brake disc and measure the brake disc thickness. Record the measurement, refer to
Specifications in this section.
If the brake disc is cracked or otherwise damaged, install a new brake disc. For additional
information, refer to Section 206-03 for front brakes.
If the measurement is below the minimum thickness specification, install a new brake disc.
For additional information, refer to Section 206-03 for front brakes.
If the diagnosis has revealed vibration in the steering wheel, seat or pedal while braking
that varies with vehicle speed, machine the brake disc. Heavily scored brake discs, similar
to that caused by pads worn down to the backing plate, should also be machined. In order
to machine, discs must be above the minimum thickness specification. For additional
information, refer to Specifications and Brake Disc Machining in this section.
Brake Drums
NOTE: It is generally not required to install new brake drums to address noise issues.
1. Inspect the brake drums and measure the brake drum diameter. Record the measurements, refer
to Specifications in this section.
If the brake drum is cracked or otherwise damaged, install a new brake drum.
If the diameter measurement is more than the maximum specification, install a new brake
drum.
Heavily scored brake drums, similar to that caused by shoes worn down to the backing
plate, should be machined. In order to machine, drums must be below the maximum
diameter specification.
For additional information, refer to Section 206-02 .

If the wheel cylinder is leaking or otherwise damaged, install a new wheel cylinder. For
additional information, refer to Section 206-02 .
Brake Calipers
1. Inspect the brake calipers for leaks, damage to seals, and piston corrosion or binding.
If the brake caliper is leaking or otherwise damaged, install a new brake caliper. For
additional information, refer to Section 206-03 for front brake calipers.
Brake Caliper Guide Pins
1. The guide pins should slide with a reasonable amount of hand force. If the brake pads show taper
wear or the guide pins are difficult to move, carry out the following steps.
Disassemble the brake caliper guide pins and inspect the guide pins and guide pin bores
for wear, damage and corrosion. If bore is worn or damaged, replace the damaged
component.
Use a wire brush, rolled-up sandpaper or emery cloth to remove all corrosion and foreign
material from the caliper guide pin bores. Clean any remaining foreign material from the
bores with brake parts cleaner and compressed air.
Assemble the caliper guide pins using new caliper seals, boots and guide pins. Use an
ample amount of the specified grease to lubricate the bores and guide pins.
Inspect the brake pads. For additional information, refer to Brake System Inspection in this
section.
Brake Flexible Hoses and Tubes
NOTICE: Never use copper tubing. It is subject to fatigue, cracking and corrosion, which may
result in brake tube failure.
NOTE: Double-wall steel tubing is used throughout the brake hydraulic system. All brake tube fittings
must be correctly double flared to provide strong, leakproof connections. When bending tubing to fit the
underbody or rear axle contours, be careful not to kink or crack the tube.
1. Inspect brake tubes for corrosion, cracks, leaks or any other signs of damage.
If a section of the brake tube is damaged, the entire section must be installed with a new
tube of the same type, size, shape and length.
When installing the hydraulic brake tubing, hoses or connectors, tighten all connections to
specifications. After installation, bleed the brake system. For additional information, refer to
Brake System Bleeding in this section.
2. Inspect the brake flexible hoses for cracks, leaks and swelling during brake application or any
other signs of damage.
Install a new brake flexible hose if the hose shows signs of softening, cracking or other
damage. For additional information, refer to Section 206-03 for the front brake flexible hose
or Section 206-02 for the rear brake flexible hose.
Brake Master Cylinder
NOTE: During normal operation of the brake master cylinder, the fluid level in the brake master cylinder
reservoir will fall during brake application and rise during release. The net fluid level (such as after brake
application and release) will remain unchanged. Fluid level will decrease with pad wear.
NOTE: A trace of brake fluid will exist on the booster shell below the master cylinder mounting flange.
This results from the normal lubricating action of the master cylinder bore and seal.
1. Inspect the brake master cylinder for fluid leaks.
Install a new master cylinder or brake fluid reservoir if signs of excessive leaking are
present. For additional information, refer to Section 206-06 .
To check for correct brake master cylinder operation, refer to Component Tests in this
section.

Brake Disc Machining
NOTE: Do not use a bench lathe to machine the brake discs. Use an on-vehicle brake lathe only. Read
the entire operating manual and/or view the video shipped with the lathe before installing, operating or
repairing the lathe.
NOTE: An on-vehicle brake lathe with an automatic runout adjustment feature is preferred. However, if
the lathe is not self adjusting, the lathe oscillation must be adjusted using a dial indicator. The total
indicated runout target is 0.000 mm (0.000 in). The maximum indicated runout should be no more than
0.050 mm (0.002 in). If the runout adjustment (automatic or manual) is carried out correctly prior to
machining, then the final brake disc runout will be within specification, and a runout measurement is not
necessary after machining.
NOTE: Do not machine new brake discs.
NOTE: Lateral runout and disc thickness variation measurements are not required because correct
adjustment of the on-vehicle brake lathe will make sure that these dimensions are within specifications.
1. Remove the wheel and tire. For additional information, refer to Section 204-04 .
2. NOTICE: Do not allow the caliper to hang from the brake hose or damage to the hose may
occur.
NOTE: It is not necessary to disconnect the brake tube from the brake caliper.
Remove the bolts and position the brake caliper or brake caliper and anchor plate assembly
aside, as required.
Support the brake caliper using mechanic's wire.
3. Install the hub adapter using:
four wheel nuts on a 4-stud wheel hub.
five wheel nuts on a 5-stud wheel hub.
six wheel nuts on a 6-stud wheel hub.
four wheel nuts on a 7- or 8-stud wheel hub.
five wheel nuts on a 10-stud wheel hub.
4. Install the cutting lathe.
5. If the lathe is not self adjusting, adjust the lathe oscillation using a dial indicator. The total
indicated runout target is 0.000 mm (0.000 in). The maximum indicated runout should be no more
than 0.050 mm (0.002 in).
6. Center the cutting head, adjust the cutting bits and install the chip deflector/silencer.
7. NOTE: The depth of the cut should be between 0.10 and 0.40 mm (0.004 and 0.015 in). Lighter
cuts will cause the bit to heat up and wear faster. Heavier cuts will cause poor brake disc surface
finish.
Machine the brake disc.
8. Remove the lathe and the silencer.
9. Remove the wheel nuts and hub adapter.
10. Remove the metal shavings.
11. Measure the brake disc thickness.
If the measurement is below the minimum specification, install a new brake disc. For
additional information, refer to Section 206-03 .
12. NOTE: It is not required to install new brake pads if friction material is within specifications. For

Drum Brake
The drum brake system consists of the following components:
Brake backing plate
Brake drum
Brake flexible hose
Brake shoe hardware kit
Brake shoes
Self-adjuster
Wheel cylinder
When mechanical force is applied by the driver to the brake pedal, the force is converted into hydraulic
pressure by the master cylinder. The hydraulic force is directed to the wheel cylinders moving the brake
shoes against the friction surface of the brake drum. The friction of the brake shoes on the brake drum
causes the slowing or stopping of wheel rotation and the vehicle.

Hydraulic Brake Actuation
The hydraulic brake actuation system consists of the following components:
Brake master cylinder and fluid reservoir
Brake pedal and bracket
Brake tubes and hoses
The brake pedal is connected to the power brake booster, which is connected to the brake master
cylinder. When the brake pedal is pressed, brake fluid is pushed through the double-walled steel tube
and flexible hoses to the front brake calipers and rear wheel cylinders. The brake fluid enters the
calipers and cylinders, forcing the pistons and brake pads/shoes outward against the friction surface,
slowing or stopping rotation. When the brake pedal is released, brake fluid pressure is relieved, returning
the caliper pistons, wheel cylinders, brake pads and brake shoes to the unapplied position.

Brake Booster
The brake booster consists of:
brake booster assembly
brake booster vacuum hose
brake booster vacuum check valve
The brake booster is a single-diaphragm type which utilizes engine vacuum to reduce brake pedal effort
and travel. The brake booster is divided into separate vacuum and atmospheric chambers by the
diaphragms. Engine vacuum is supplied to the brake booster through the brake booster hose and a oneway check valve. The check valve retains the engine vacuum in the brake booster and allows for several
power-assisted brake applications with the engine off.
When the brake pedal is applied, vacuum replaces the atmospheric pressure in the brake booster,
reducing the effort required at the brake pedal to slow the vehicle. When the brake pedal is released,
vacuum returns to the brake booster through the brake booster vacuum hose and check valve.

SECTION 206-09: Anti-Lock Brake System (ABS) and Stability Control
DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 11/04/2010
Anti-Lock Control
Anti-Lock Braking
The ABS consists of the following components:
ABS module — attached to the Hydraulic Control Unit (HCU) and cannot be serviced separately
from the HCU .
HCU — which contains several valves (inlet, outlet, isolation and dump) and the hydraulic pump
motor. The HCU is mounted on the RH side of the engine compartment and is serviced with the
ABS module.
Front wheel speed sensors — one sensor is located in each front wheel knuckle. The sensors are
serviced separately from the knuckle.
Rear wheel speed sensors — one sensor is located at each rear wheel end, is mounted to the
brake backing plate and can be serviced separately.
Wheel bearing magnetic strip — the wheel bearing magnetic strip is part of the wheel bearing and
is serviced with the bearing.
ABS aids in the prevention of wheel lock-up during braking events allowing the driver to maintain
steering control and stop in the shortest distance possible under most conditions. This is accomplished
by the ABS module and HCU modulating brake fluid pressure to the affected brake caliper(s) and wheel
cylinder(s).
When the ABS activates, the driver may notice the following operational symptoms:
A rumble or grinding sound may be heard ( HCU pump motor)
If the driver's foot is on the brake pedal, a vibration may be felt in the brake pedal ( HCU pump
motor and valves)
Electronic Brake Distribution (EBD)
The ABS module and HCU incorporate a strategy called Electronic Brake Distribution (EBD). The EBD
strategy uses the HCU as an electronic proportioning valve to create a balanced braking condition
between the front and rear wheels and minimize the chance of rear wheel lockup during hard braking. A
slight bump sensation may be felt in the brake pedal when EBD is active.
ABS with Advance Trac®
The ABS with Advance Trac® system consists of the same components as the conventional ABS above
with the following additional components:
Stability control sensors — located inside the Restraints Control Module (RCM) under the front
floor console, and contains several sensors (yaw rate, lateral and longitudinal accelerometers).
Steering wheel rotation sensor — is part of the Electronic Power Assist Steering (EPAS) column
assembly and is not available separately for service.
The Advance Trac® system is comprised of traction control and Electronic Stability Control (ESC). ABS
and the traction control portion of the Advance Trac® system will operate with the transmission in
reverse gear, but ESC will be disabled.
Traction Control System
The traction control system aids in the prevention of excessive wheel spin which allows the vehicle to
maintain traction during acceleration. This is accomplished in the same manner as anti-lock braking
(brake traction control) but also includes using the PCM for modulating engine torque (engine traction
control). The traction control system can be disabled by the driver through the message center. The
system will remain disabled until the driver enables it through the message center or until the ignition is
cycled to OFF and back to RUN.
Electronic Stability Control (ESC) System
The ESC system constantly monitors vehicle direction of travel relative to the intended course and aids
in keeping the vehicle traveling along that course. The ESC also aids in keeping the vehicle stable
during sudden or abrupt maneuvers. This is accomplished in the same manner as anti-lock braking and
traction control. ESC cannot be disabled by the driver.
When either of these 2 systems activate, the driver may notice the same operational symptoms as ABS
along with the following additional symptoms:
A small deceleration or a reduction in the acceleration of the vehicle (PCM modulating engine
torque)
The stability/traction control indicator (also known as the sliding-car icon) flashes (indicating a
traction or stability event is taking place)
Stability/Traction Indicator
The stability/traction indicator (also known as the sliding-car icon) is located in the Instrument Panel
Cluster (IPC). It alerts the driver to a stability/traction event taking place (flashes twice per second) and
to alert the driver of potential concerns in the AdvanceTrac® system (illuminates solidly).
Stability/Traction OFF Indicator
The stability/traction OFF indicator (also known as the sliding-car OFF icon) is located in the IPC .
Illumination of the indicator confirms to the driver that the brake traction control portion of the Advance
Trac® system has been disabled when the TRACTION CNTRL setting in the message center is set to
OFF.
Hill Start Assist (Automatic transmission only)
Hill start assist helps the driver when accelerating from a stop on an incline or side of a hill. Hill start
assist supports the driver during drive-off situations on upward gradients. When the driver releases the
vehicle brake, hill start assist prevents the vehicle from rolling back in the opposite direction.

Principles of Operations
Anti-Lock Braking
The ABS module continuously monitors and compares the rotational speed of each wheel. This is
accomplished through the use of 4 active wheel speed sensors, 1 for each wheel. The wheel speed
sensors are connected to the ABS module by 2 circuits. One circuit provides voltage for sensor
operation and the other circuit provides sensor input to the ABS module. As the wheels spin, the wheel
bearing magnetic strip passes through the magnetic field generated by the active wheel speed sensor.
The active wheel speed sensor sends a square wave signal to the ABS module to indicate individual
wheel speed.
The ABS module uses a Hydraulic Control Unit (HCU) to isolate and modulate hydraulic pressure to the
caliper(s) and wheel cylinder(s). The HCU contains several solenoid-controlled valves, a pump motor, an
accumulator and several sensors. The fluid flows through 4 normally open inlet valves inside the HCU ,
and through the outlet ports of the HCU to the brake calipers and wheel cylinders. If the ABS module
senses that a wheel is nearing a lockup condition based on wheel speed sensor data and deceleration
algorithms, the module closes the normally open inlet valve for that wheel. This isolates the
corresponding caliper or wheel cylinder. The ABS module reads the wheel speed sensor signal from the
affected wheel again. If the wheel is still decelerating (locking up), the module opens the normally closed
outlet valve allowing a controlled amount of hydraulic pressure in the brake caliper to be relieved into the
HCU accumulator. The ABS pump motor runs during an ABS braking event so sufficient brake fluid
pressure is consistently available to the HCU valves. This procedure of closing and opening valves is
repeated several times per second until the speed of the affected wheel matches the speeds of the other
wheels. Once this has been accomplished, the ABS module returns the solenoid valves to their normal
position.
The ABS module is self-monitoring. When the ignition is turned to the RUN position, the ABS module
carries out a preliminary electrical check of the wheel speed sensor circuitry by sending voltage through
the sensor and checking for the voltage to return. At speeds above 20 km/h (12 mph), without the brake
pedal being pressed, the pump motor is commanded on for approximately one-half second to check
pump motor operation. Also, during all phases of operation while the vehicle is in motion, the ABS
module checks for correct operation of the wheel speed sensors. In the event the ABS module detects a
concern, the module sets a DTC and sends a message to the Instrument Panel Cluster (IPC) over the
High Speed Controller Area Network (HS-CAN) to illuminate the yellow ABS warning indicator and/or the
stability/traction control indicator (sliding-car icon). If the concern is severe enough, ABS may be
disabled. Normal power-assisted braking, however, remains.
Electronic Brake Distribution (EBD)
The ABS module incorporates a strategy called Electronic Brake Distribution (EBD). The EBD strategy
uses the HCU as an electronic proportioning valve. On initial application of the brake pedal, full pressure
is applied to the rear brakes. The ABS module uses wheel speed input to calculate an estimated rate of
deceleration. Once vehicle deceleration exceeds a certain threshold, the ABS module closes the
appropriate solenoid valves in the HCU to hold the rear brake pressure constant while allowing the front
brake pressure to build. This creates a balanced braking condition between the front and rear wheels
and minimizes the chance of rear wheel lockup during hard braking. As the vehicle decelerates, the
valves are opened to increase the rear brake pressure in proportion to the front brake pressure.
If there is a DTC in the ABS module specifically for the HCU or there are 2 or more wheel speed sensor
DTCs set, EBD is disabled. When EBD is disabled, the ABS warning indicator, the red brake warning
indicator and the stability/traction control indicator (sliding-car icon) illuminate.
AdvanceTrac® Stability Enhancement System
The AdvanceTrac® system provides the following stability enhancement features for certain driving
situations:
Traction Control System — helps to avoid excessive drive-wheel spin and loss of traction.
Electronic Stability Control (ESC) System — helps to avoid skids and lateral slides.
Traction Control System
The traction control system uses the ABS and the PCM to limit wheel spin. When the ABS module
detects a wheel spinning excessively, brake pressure to the appropriate brake caliper is modulated. This
is accomplished by opening and closing the appropriate solenoid valves inside the HCU while the
hydraulic pump motor is activated. At the same time, the ABS module sends a message over the HSCAN that a traction control event is taking place. When the IPC receives this message, it flashes the
stability/traction control indicator (sliding-car icon). If the event is severe enough, the ABS module sends
a message to the PCM over the HS-CAN to assist with traction control. When the PCM receives this
message, it adjusts engine timing and decreases fuel injector pulses. Once the affected wheel returns to
normal speed, the ABS module returns the solenoid valves in the HCU to their normal position,
deactivates the hydraulic pump motor and sends another message over the HS-CAN indicating the
traction event has ended. The PCM returns engine timing and fuel injectors to normal operation and the
IPC extinguishes the sliding-car icon.
Once vehicle speed reaches or exceeds 100 km/h (62 mph), traction control is accomplished only
through PCM intervention.
Certain DTCs in the ABS module disable the traction control system. Depending on the DTCs present,
the yellow ABS warning indicator and/or the sliding-car icon is illuminated.
The driver is able to enable and disable the traction control portion of the Advance Trac®. This is
independent of the ABS and ESC functions, which cannot be disabled by the driver. To disable or
enable the traction control system, the TRACTION CNTRL setting in the message center is changed
from ON to OFF. When the driver disables the traction control system, the IPC communicates traction
control system status to the ABS module over the HS-CAN bus. The ABS module will no longer
intervene when a traction event is detected. The ABS module sends a message to the IPC over the to
HS-CAN bus illuminate the stability/traction control OFF indicator (sliding-car OFF icon), which indicates
to the driver that the traction control system is disabled. The system automatically restores to full
functionality when the ignition is cycled to OFF and then back to RUN.
Electronic Stability Control (ESC) System
The ESC system is controlled by the ABS module and uses the same wheel speed sensors and wheel
bearing magnetic strips used for anti-lock braking. The ESC system also uses input from the stability
control sensors for the ESC system to help maintain vehicle stability. They include the yaw rate sensor,
lateral accelerometer and longitudinal accelerometer and are located in the Restraints Control Module
(RCM).
The ABS module uses the various sensors to continuously monitor vehicle direction of travel relative to
the intended course. If the ABS module determines from all these inputs that the vehicle is unable to
travel in the intended direction, it modulates brake pressure to the appropriate brake caliper(s) or wheel
cylinder(s) by opening and closing the appropriate solenoid valves inside the HCU while the hydraulic
pump motor is activated. At the same time, the ABS module sends a message over the HS-CAN that a
stability event is taking place. When the IPC receives this message, it flashes the sliding-car icon. Under
certain conditions during a stability event, the PCM may be requested to reduce engine torque as it does
for traction control. Once the stability condition has been corrected, the ABS module sends another
message over the HS-CAN indicating that the event has ended. The PCM returns engine timing and fuel
injectors to normal operation and the IPC extinguishes the sliding-car icon.
Certain DTCs being present in the ABS module may disable the ESC system. Depending on the DTCs
present, the yellow ABS warning indicator and/or the sliding-car icon is illuminated.
Hill Start Assist (Automatic transmission only)
Hill start assist helps the driver when accelerating from a stop on an incline or side of a hill. Hill start
assist supports the driver during drive-off situations on upward gradients when the driver releases the
vehicle brake by preventing the vehicle from rolling back in the opposite direction. The system engages
automatically when the following conditions are met:
Road inclination of approximately 4 degrees or more is detected.
The driver applies the vehicle brake and the vehicle is at a complete stop.
The vehicle transmission information must indicate that the driver intends to drive up the hill.
The parking brake is not engaged.
When the driver releases the brake pedal in drive gear, hill start assist holds the car stationary for up to
3 seconds giving the driver time to accelerate the vehicle. As the vehicle accelerates hill start assist
gradually reduces the brake pressure to ensure that the vehicle is neither rolling back nor driving off until
there is sufficient driving torque to accelerate the vehicle forward. Hill start assist functions if the vehicle
is facing downhill if the reverse gear is selected.
There is 1 message displayed by the multifunction display that informs the driver of the status of the hill
start assist. HILL START ASSIST NOT AVAILABLE is displayed and the hill start assist telltale in the
IPC is illuminated when it is not available.
Stability Control Sensors
The stability control sensors for the ESC system include the yaw rate sensor, lateral accelerometer and
longitudinal accelerometer. The sensors are housed in the RCM which sends sensor information to the
ABS module over a dedicated Controller Area Network (CAN). If any of the sensors are defective, install
a new RCM .
The yaw rate sensor measures the relative vehicle motion about the vertical axis through its
center of gravity.
The lateral accelerometer measures the acceleration that corresponds to the force involved when
the vehicle moves sideways.
The longitudinal accelerometer measures the acceleration corresponding to the force involved
when the vehicle moves forward and rearward in the horizontal plane, along the centerline of the
vehicle front and rear wheels.
Lateral acceleration has 2 forms. The first is the centrifugal acceleration that occurs when the vehicle
travels around in a circle. The second is the acceleration due to gravity. On level ground there is no
contribution from this acceleration. However, if the vehicle is parked sideways on a bank or incline, the
sensor measures some lateral acceleration due to gravity, even though the vehicle is not moving.
Steering Sensor
The Power Steering Control Module (PSCM) uses the steering sensor to determine speed and rotation
direction of the steering wheel. This information is transmitted to the ABS module along the HS-CAN .
The sensor is attached to the Electronic Power Assist Steering (EPAS) column assembly and cannot be
serviced separately.
ABS Module Configuration
ABS module configuration is a scan tool process which configures specific vehicle settings in a new ABS
module. If installing a new ABS module, it must be configured. Refer to Programmable Module
Installation (PMI) in Section 418-01 .
ABS Module Calibration
The calibration procedure is also required for the ABS module to learn the "zero-position" of the steering
and stability control sensors.
To calibrate the ABS module, connect the scan tool and carry out the IVD Initialization sequence,
following the scan tool directions. The vehicle must be on a level surface and not moving during
calibration. If a DTC is retrieved after calibration, refer to the ABS Module DTC Chart in this section.

Pinpoint Test A: DTCs C0020:13, C0020:71
Refer to Wiring Diagrams Cell 42 , Vehicle Dynamic Systems for schematic and connector information.
Normal Operation
The ABS module uses an internal solid state switch to operate the ABS pump motor. The ABS module
tests the ABS pump motor by activating it for 30 milliseconds. While the pump motor is being activated,
the ABS module monitors the voltage drop across the ABS pump motor solid state switch and the
amount of current the ABS pump motor draws through the solid state switch. If the voltage drop is too
high or if the ABS pump motor is drawing too much current, the ABS module sets a DTC. After 30
milliseconds have passed, the ABS module stops applying voltage to the pump motor and observes the
voltage that the spinning ABS pump motor is generating. The voltage generated by the motor indicates
how fast the motor is spinning. Voltage that is too low indicates that the motor is not spinning freely and
a DTC sets.
The ABS module uses fused battery voltage from Battery Junction Box (BJB) to power the ABS pump
motor. The ABS module provides ground for the ABS pump motor. Insufficient power or ground along
the circuits causes multiple DTCs to set.
C0020:13 (ABS Pump Motor Control: Circuit Open) — this DTC sets if the voltage supplied to the
ABS module is less than 10 volts, if there is an open or high resistance on the ABS pump motor
circuit between the ABS module and the Hydraulic Control Unit (HCU), or if the ABS module is
faulted internally.
C0020:71 (ABS Pump Motor Control: Actuator Stuck) — this DTC sets if the ABS module detects
that the ABS pump motor is not rotating when it is commanded to run.
This pinpoint test is intended to diagnose the following:
Fuse

Pinpoint Test C: DTCs C0044:28, C0044:49 and C0044:64
Normal Operation
The ABS module uses internal pressure sensors to determine correct operation by monitoring internal
Hydraulic Control Unit (HCU) hydraulic pressures. These DTCs set if the brake pressure sensor signals
do not match. This fault could set by either an internal ABS module failure or a pressure sensor failure.
The pressure sensors are internal to the HCU and cannot be serviced separately.
DTC C0044:28 (Brake Pressure Sensor "A": Signal Bias Level Out of Range / Zero Adjustment
Failure) — this DTC sets if the brake pressure sensor signals do not match. This fault could set
by a misadjusted stoplamp switch or improperly installed brake pedal. An internal ABS module
failure or a pressure sensor failure can also cause this DTC to set. When the ABS module sets
DTC C0044:28, a message is also sent to the Transmission Control Module (TCM) along the
High Speed Controller Area Network (HS-CAN) bus. After received this message from the ABS
module, the TCM places the automatic transmission into NEUTRAL. There is no corresponding
DTC set in the Transmission Control Module (TCM).
DTC C0044:49 (Brake Pressure Sensor "A": Internal Electronic Failure) — this DTC sets if the
brake pressure sensor signals do not match. This fault could set by either an internal ABS module
failure or a pressure sensor failure.
DTC C0044:64 (Brake Pressure Sensor "A": Signal Plausibility Failure) — this DTC sets if the
brake pressure sensor signals do not match. This fault could set by either an internal ABS module
failure or a pressure sensor failure.

Normal Operation
The ABS module uses information received from several sensors (wheel speed sensors, steering wheel
rotation sensor, stability/traction control system sensors, etc.) to determine if vehicle stability or traction
warrants ESC interaction. If an event is going to occur, the ABS module adjusts the brake torque at
specific wheels and the PCM reduces engine torque to make the vehicle more stable. Once the ABS
module has determined that the stability event has been corrected, it returns the brake and engine
torque to normal and continues to monitor the vehicle. DTCs set in the ignition cycle can only be cleared
by cycling the ignition off and on once the fault has been corrected. The Restraints Control Module
(RCM) measures the yaw rate and vehicle acceleration, then sends the signal through a secondary,
dedicated Controller Area Network (CAN) to the ABS module. This dedicated CAN is used only for
communication between the RCM and the ABS module. The ABS module uses this information for
AdvanceTrac® system operation. The ABS module also compares this information to information it
receives from other sensors (brake pedal input, steering wheel) to determine how valid the information is
and to determine if an instability event is about to occur. The yaw rate sensor, lateral and longitudinal
accelerometers are contained in the RCM .

Brake Pedal Switch Adjustment
NOTICE: Do not press the brake pedal when installing or removing the brake pedal position switch or
damage to the brake pedal-mounted switches can occur.
1. Inspect both brake pedal position switches and brake pedal assembly to verify there is no brake pedal
pressure unintentionally applied due to incorrect brake pedal position switch or brake pedal installation.
Correct any concerns before proceeding to the next step.
2. Confirm that all fasteners retaining the brake pedal assembly are correctly tightened. For additional
information, refer to Section 206-06 .
3. Using the Integrated Diagnostic System (IDS) scan tool, select DataLogger->Chassis->Braking->Brake
Switch Parameters.
4. NOTE: Using the scan tool record function makes it easier to observe the brake pressure sensor
readings.
Turn the ignition to the ON position.
5. Slowly apply the brake pedal to generate the pressure graph for the BPS PID.
The rate of brake pedal apply must not exceed 5 psi per second as indicated by the scan tool.
6. Record the initial value of the BPS PID when BRAKE_LAMP and CRUISE_CANCL change from OFF to
ON.
If BRAKE_LAMP and CRUISE_CANCL transition to ON before the BPS PID reads 44 psi or less,
the brake pedal position switch is correctly installed.
If BRAKE_LAMP and CRUISE_CANCL transition to ON after the BPS PID reads greater than 44
psi, replace the stoplamp switch and cruise control deactivation switch (if equipped). Clear all DTCs
and repeat Steps 3-6 to verify that the BRAKE_LAMP and CRUISE_CANCL transition to ON

External Controls
The transaxle external controls system consists of the following components:
Selector lever assembly
Selector lever cable and bracket
Brake Shift Interlock Actuator (BSIA)
Transmission Control Switch (TCS)
The selector lever controls the transaxle gear selection through the selector lever cable. When the selector
lever is moved to the desired mode of operation it moves the selector lever cable which moves the manual
control lever on the transaxle. This results in the desired gear selection. The selector lever knob controls the
cable detent and selector lever locking position.

Location
The BSIA is part of the selector lever assembly.
The brake shift interlock system prevents the selector lever from being moved out of PARK unless the
requirements to do so are met. The ignition switch must be in the ON position and the brake pedal must be
pressed. The brake pedal position is detected by the Brake Pedal Position (BPP) switch. In the event the
vehicle will not come out of PARK, the manual release mechanism mechanically bypasses the electric portion
of the brake shift interlock system allowing the selector lever to be moved out of PARK. The manual release
mechanism is part of the selector lever assembly. If PARK is selected again, the selector lever will be locked
again.
Drive with Grade Assist
Drive with Overdrive (O/D) cancel and grade assist is activated when the Transmission Control Switch (TCS) is
pressed. The TCS is located on the selector lever knob. When the TCS is pressed, the 6th gear or O/D upshift
is prevented or the transaxle shifts down to 5th gear. The TCS is meant to be used when driving conditions
cause excessive shifting from 6th to other gears such as hilly terrain, mountainous areas or when engine
braking is required.
Grade Assist
O/D is cancelled.
The transaxle operates in gears 1 through 5.
The Grade Assist lamp illuminates on the Instrument Panel Cluster (IPC).
Improves vehicle handling in hilly terrain or mountainous areas by providing engine braking and
extending lower gear operation on uphill climbs.
Provides additional engine braking through the automatic transaxle shift strategy which reacts to vehicle
inputs (vehicle acceleration, accelerator pedal, brake pedal and vehicle speed).
The transaxle selects gears that provide the desired engine braking which is based on the vehicle inputs.
Engine braking increases engine rpm.
Returning to DRIVE mode on flat terrain provides the best fuel economy and transaxle performance. The
transaxle returns to O/D when the TCS is pressed again or the key is turned OFF.

SECTION 307-11: Automatic Shifting Manual Transmission/Transaxle
DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 02/18/2011
Transaxle Description
This DPS6 is a fully automatic, dry dual clutch, automatic shifting manual, electronically controlled 6speed transaxle.
Its abbreviated designation DPS6 means:
D — Dry Dual Clutch
P — Powershift
S — Synchronized
6 — 6-speed transaxle
This transaxle features the following:
Computer Control with electro-mechanical actuation
Two piece aluminum housing design
Six (6) discrete stepped forward gears and one (1) reverse gear
Dual Output shafts with two separate final drive ratios
Full ball and roller bearing design for all gears and shafts
All gears are bevel cut for improved NVH characteristics and power transfer
All gears are in constant mesh for no loss of torque during the shifting process
All cast construction of shift fork/linkage mechanisms
This transaxle features two nested input shafts driven by a compact dry dual clutch system. These two
shafts are used in conjunction with each other to provide seamless shifting through the six (6) available
ratios with overdrive in the two top gears. As each gear is selected, the appropriate clutch is activated to
drive the vehicle. Each consecutive gear is then preselected for the next “shift” operation as power is
shifted from one clutch to the other and back again as moving up and down through the individual gears
This transaxle is designed to be operated in the same manner as a conventional torque converter
equipped automatic transaxle. It provides the smooth application of power, but with the bonus of
efficiencies found only in a manual transaxle. By delivering the power with a dual clutch system, fluid
volume is limited to less than 2 liters as compared against a conventional automatic transaxle, and that
is only within the gearbox case itself. The actuation of the clutch system is controlled by a dedicated
computer through two individual electrically driven clutch motors and actuator systems.
This transaxle provides six (6) discrete forward ratios with overdrive in the top two gears and a reverse
gear, giving a continuous flow of power for acceleration and deceleration
The selector lever gives the driver a choice of P, R, N, D and L.
With the selector lever in the D position, you can operate the Transmission Control Switch (TCS)/Grade
Assist switch on the selector lever to prevent the transaxle from shifting into 6th gear.
If a fault occurs continued motoring is guaranteed in the following limited conditions based on the failure:
1st, 3rd and 5th gear if a fault with clutch 2 and/or relational components occurs. 2nd, 4th, 6th and
reverse if a fault with clutch 1 and/or relational components occurs.
This transaxle can be tested using a scan tool through the Data Link Connector (DLC) in the passenger
compartment.
Internal components are based on manual transaxle technologies that include:
Dry friction clutches to transmit power between the engine and transaxle
Lay shaft gearing for high efficiency and uncoupled ratio selection
Rotating sequential shift drums for fast response
Synchronizers with dog clutches to pre-select and direct the power flow
Splash fluid lubrication without filter and external oil coolers
This transaxle is two transaxles within one housing that share a common:
Final drive which includes two output shaft pinions
Differential assembly
Output Shaft Speed (OSS) sensor
Transmission Range (TR) sensor
Park system
Transmission Control Module (TCM)
The first consists of three odd gear ratios (1st, 3rd & 5th):
Odd input clutch and actuator system including a clutch motor
Odd or inner input shaft with input shaft speed sensor 1 and related speed gears
Odd synchronizer system including a shift motor (part of TCM ), shift drum, shift forks and transfer
assemblies.
The second consists of three even gear ratios and reverse (2nd, 4th, 6th & Reverse):
Even input clutch and actuator system including a clutch motor
Outer or hollow input shaft with input shaft speed sensor 2 and related speed gears.
Even synchronizer system including a shift motor (part of TCM ), shift drum, shift forks and
transfer assemblies
1st Gear
The torque is introduced into the dual clutch via the flywheel. From there, the power is transmitted via
clutch 1 to the inner input shaft. The inner input shaft transmits the torque to the first gear of the output
shaft. The torque is transmitted to the differential via the output pinion.
2nd Gear
The torque is introduced into the dual clutch via the flywheel. From there, the power is transmitted via
clutch 2 to the hollow input shaft. The inner input shaft transmits the torque to the second gear of the
output shaft. The torque is transmitted to the differential via the output pinion.
3rd Gear
The torque is introduced into the dual clutch via the flywheel. From there, the power is transmitted via
clutch 1 to the inner input shaft. The inner input shaft transmits the torque to the third gear of the output
shaft. The torque is transmitted to the differential via the output pinion.
4th Gear
The torque is introduced into the dual clutch via the flywheel. From there, the power is transmitted via
clutch 2 to the hollow input shaft. The hollow input shaft transmits the torque to the fourth gear of the
output shaft. The torque is transmitted to the differential via the output pinion.
5th Gear
The torque is introduced into the dual clutch via the flywheel. From there, the power is transmitted via
clutch 1 to the inner input shaft. The inner input shaft transmits the torque to the fifth gear of the output
shaft. The torque is transmitted to the differential via the output pinion.
6th Gear
The torque is introduced into the dual clutch via the flywheel. From there, the power is transmitted via
clutch 2 to the hollow input shaft. The hollow input shaft transmits the torque to the sixth gear of the
output shaft. The torque is transmitted to the differential via the output pinion.
Reverse
The torque is introduced into the dual clutch via the flywheel. From there, the power is transmitted via
clutch 2 to the hollow input shaft. The hollow input shaft now transmits the torque to the reverse/2nd
double gear which acts as an idler gear to reverse the direction of rotation. This idler transmits torque to
the reverse gear of the output shaft. The torque is transmitted to the differential via the output pinion.

Main Components and Functions
This transmission system has been divided into 6 sub-systems that relate to specific functional areas. These
sub-systems are:
a clutch/actuator system which transfers engine crankshaft speed and torque.
an active input system which includes applied clutch disc, bearings, speed gears and output shaft.
a passive input system which includes disengaged clutch disc, bearings, speed gears and an output
shaft system.
a synchronizer/engagement system which includes a torque carrying interface between speed gear and
output shaft.
a differential system that is the final drive output system which includes drive pinions, ring gear, support
bearings and side gears.
an electrical control system which includes control system logic, Transmission Control Module (TCM),
speed sensors, electric motors and a wire harness.

The clutch and actuator sub – system consists of engine crankshaft mounted rotating components. These
include, a center flywheel, odd and even clutch pressure plates, clutch actuating mechanisms and engagement
components. The clutch actuators are independent systems within the clutch housing that apply an axial force
to the clutch diaphragm springs causing their respective clutch to apply. This apply force is reacted back into
the transaxle through the input shaft unlike a manual transaxle dry clutch system, no thrust is applied to the
engine crankshaft. Normally the clutch capacity commands are mutually exclusive (to prevent tie-up) with minor
overlaps to allow synchronous shifting. A clutch “touch point” position must be established by a learning
algorithm within the system software. Establishing the touch point is the system’s method for ensuring that the
displacement-based clutch actuation system is properly calibrated. This is necessary so that the clutch capacity
can be controlled correctly by the TCM and be engaged and released to the required torque capacity and within
the required time.

The active input system of the transaxle can be viewed as two transaxles within a common housing (one for
1st, 3rd & 5th and another for Reverse, 2nd, 4th & 6th). For any driving gear there is one transaxle actively
engaged in the power flow between the engine and the wheels and one that is disconnected or passive. This
section will discuss considerations for the driving input shaft system whether it be the ODD or EVEN transaxle.
The driving or active input shaft system consists of the input shaft and clutch disc, support bearings and the
meshed speed gears with their needle roller bearings.

The synchronizer systems are comprised of single and dual cone synchronizer systems. The synchronizers are
designed to act as the torque carrying interfaces between each speed gear and corresponding output shaft.
The synchronizer design and function are similar to manual transaxle operations.
Basic Synchronizer Hardware Operation
As in manual transaxle operation, gear pre-selection is made by sliding the synchronizer sleeve towards a
speed gear. This causes the internal splines of the synchronizer sleeve to bridge a gap between the output hub
and the external spline feature of the speed gear, thus transmitting speed and torque between the gear and
output shaft. Synchronizers are small cone wet friction clutches mounted to the transaxle output shaft. They are
used to bring the rotation speed of the engaging speed gear in sync with the output shaft speed. After
synchronous speed has been attained the final power flow connection is made possible and the synchronizer
sleeve is permitted to pass by and engage the external spline teeth on the speed gear.

The shift system consists of two independent sub-systems for controlling the transaxle synchronizer pre –
selections and engagements. Using this arrangement provides an independent control of the two transaxles
and a mechanical interlock that prevents two gears within the same transaxle from being engaged
simultaneously. The TCM houses two electric motors that mesh with and drive the first double gear wheel,
which drives the second double gear which finally drives the shift drum. Gearing between the shift motors and
the drums reduce speed and multiply torque. Position sensors in the TCM detect feedback of the motor angular
position. Shift drum position is learned by the TCM during a teach-in process that involves rotating each drum
against hard stops located on the shift drum and the transaxle housing.

The output shaft system consists of the output shaft gears, differential ring (final drive) gear and the differential
assembly. Typically when a vehicle is traveling down the road both wheels are rotating at the same speed;
however, when a vehicle is turning, the outside wheel must travel a greater distance than the inside wheel. To
do this, in the same time, the outside wheel must rotate faster than the inside wheel. The differential is
designed to provide speed compensation for the wheels to allow the vehicle to negotiate turns smoothly.

Two electrical clutch motors are used to actuate the dual clutch in the transmission – one motor for each
clutch. The motors work independently of each other. When the clutch is fully closed, the clutch motor
provides the holding torque in addition with spring force. The clutch motors work against a clutch spring
and self disengage with no electrical power.
TR sensor detects the angular position of the shift lever shaft.
TCM is an assembly of an electronic module, sensors, and electrical motors.
The TCM 's electrical motors (2) control the mechanical shift fork system. The shift drums are the link
from electrical to mechanical operation. The TCM collects incoming vehicle, transmission and driver
demand signals and uses these signals to select the next required gear ratio. The TCM receives
transmission sensor signals and transmits clutch motor current through externally mounted wire harness.
The TCM uses these signals to control shift feel.

Transaxle Electronic Control System
Overview Electronic Transaxle Control
The electronic transaxle control system includes:
a Transmission Control Module (TCM)
a Transmission Range (TR) sensor
an Output Shaft Speed (OSS) sensor
2 input shaft speed sensors each with pre-measured shims.
2 shift motors
2 clutch motors
a Brake Pedal Position (BPP) switch
a Brake Shift Interlock Actuator (BSIA)
a starter inhibitor relay
an Transmission Control Switch (TCS)/Grade Assist button
an TCS /Grade Assist Indicator
Electrical System Components
Transmission Control Module (TCM)
The TCM is an assembly of an electronic module, sensors, and electrical actuators. It combines a
control module and two electric motors for gear shifting. The primary function of TCM is to collect
incoming data signals to control the transaxle, perform the interpretation of incoming data signals,
communicate with the periphery and connect the electrical and mechanical contact to the signal
transmitter and actuating elements. Vehicle and transaxle interface is achieved via two connectors;
vehicle and transaxle connector. The transaxle connector plug is located at the TCM and is the electrical
connection between the TCM and the clutch actuators and the sensors. The vehicle connector is located
at the TCM and is the electrical connection between TCM and the vehicle. The TCM is a programmable
module.
Transmission Range (TR) Sensor
The TR sensor detects the position of the manual control lever shaft. The TR sensor is mounted on the
transaxle. The TR sensor allows the vehicle to start in PARK and NEUTRAL positions. The TR sensor
output signal is linear over the measurement range and the TCM receives the selector lever position.
The signals of the TR sensor are used for the following functions:
to recognize the selector lever position.
to actuate the starter inhibitor relay.
to actuate the reversing lamps.
No substitute signal is available for the TR sensor.
If the connection is cut, the vehicle cannot be started.
The TR sensor requires to be calibrated through the adaptive learning procedures.
Output Shaft Speed (OSS) Sensor
The OSS sensor measures the speed of the output shaft. The rotation direction is not measured.
The OSS sensor is located in the clutch housing above the differential.
The OSS sensor is an inductive sensor which detects the vehicle speed by means of an impulse ring on
the differential.
The signal is used for the following functions among other things:
to determine the shift timing.
to supply the vehicle speed input signal for the TCM .
Input Shaft Speed Sensors
Input shaft speed sensor 1 measures the input speed and the rotating direction of the input shaft 1. The
input shaft can be stationary. Therefore it is necessary, that the sensor system can detect the stationary
state of the input shaft accurate. By being stationary the sensor must not indicate speed unequal to 0
(also not, if the motor runs by high speeds). The slow rolling of the car has to be detected safely.
Input shaft speed sensor 2 measures the input speed of the input shaft 2. The rotation direction is not
measured.
Shift Motors
Two electric motors are used to shift the gears in the transaxle, one motor for gears 1-3-5 and one motor
for gears R-2-4-6. The gear shifting is made by two shift drums connected to shift motor pinion via two
ideal gears. The max shifting force is 1500 N (337 lb). The motors are integrated in the TCM and work
independently of each other.
Clutch Motors
Two electrically commuted motors are used to actuate the double clutch in the transaxle – one motor per
clutch. The motors work independently of each other. When the clutch is fully closed, the motor provides
the holding torque in addition with spring force. The clutch motors work against a clutch spring and are
disengaged when they reach the zero position (rest position) with the spring force.
Brake Pedal Position (BPP) Switch
The BPP switch is mounted on the brake pedal bracket.
The signal of the BPP switch is used by the PCM for the following functions:
to activate the Brake Shift Interlock Actuator (BSIA) when the brake pedal is pressed in PARK.
No substitute signal is available for the BPP switch.
If the connection to the BPP switch is cut, the selector lever cannot be moved out of PARK.
Brake Shift Interlock Actuator (BSIA)
When the ignition is switched to the ON or RUN position, the BSIA is actuated by pressing the brake
(signal from the BPP switch). This retracts the blocker so that the selector lever can be moved out of
PARK.
Brake Shift Interlock Override
NOTE: If PARK is selected again, the selector lever is locked again.
If the brake signal should fail due to a malfunction, manual unlocking of the selector lever is possible.
For this, the release of the mechanism must be done by removing the side console panel and using a
suitable tool press the BSIA lever until the selector lever can be moved out of PARK.
Starter Inhibitor Relay
The relay prevents the engine starting in selector lever positions R, D and L.
The relay obtains the information about the position of the selector lever directly from the TR sensor.
Transmission Control Switch (TCS) Button
The TCS button is located on the selector lever.
Grade Assist improves vehicle handling in hilly terrain or mountainous areas by providing additional
engine braking and extends lower gear operation on uphill climbs. Additional engine braking is provided
through the automatic transaxle shift strategy which reacts to vehicle inputs including vehicle
acceleration, accelerator pedal, brake pedal and vehicle speed. The transaxle will select gears that will
provide the desired engine braking, based on the vehicle inputs, the engine rpm during engine braking
will increase. It is recommended to return to DRIVE mode on flat terrain to provide the best fuel
economy and transaxle function. The transaxle returns to Overdrive (O/D) and grade assist is cancelled
when the TCS is pressed again.
TCS /Grade Assist Indicator
The TCS /Grade Assist indicator is located in the Instrument Cluster (IC).
It tells the driver that shifting into 6th gear is prevented by the transaxle control.
The O/D /Grade Assist light flashes to tell the driver that the transaxle control has switched to the
emergency operating mode.
Emergency Operating Program
If correct gear shifting can no longer be guaranteed due to failure of certain signals, the TCM changes to
an emergency operating program.
The driver is informed of the operation of the emergency operating program by the illumination of the
powertrain warning indicator in the IC .
Continued motoring is guaranteed in the following limited conditions based on the failure:
1st, 3rd and 5th gear if a fault with clutch 2 and/or relational components occurs.
2nd, 4th, 6th and reverse if a fault with clutch 1 and/or relational components occurs.

Troubleshooting an electronically-controlled automatic transaxle is simplified by using the proven
method of diagnosis. One of the most important things to remember is that there is a definite procedure
to follow.
Preliminary Inspection
Verify the concern by operating the vehicle.
Check the transmission fluid levels and condition.
Check selector lever linkages for correct adjustment.
Diagnostics
Carry out On-Board Diagnostic (OBD) procedures Key ON Engine OFF (KOEO) and Key ON
Engine Running (KOER).
Record all DTCs.
Repair all non-transaxle DTCs first.
Repair all transaxle DTCs second.
Erase all continuous DTCs and attempt to repeat them.
Repair all continuous DTCs.
If only pass DTCs are obtained, proceed to the Diagnosis by Symptom Index. Refer to Diagnosis
By Symptom in this section for further information and diagnosis.
Follow the diagnostic sequence to diagnose and repair the concern the first time.

DIAGNOSIS AND TESTING
2011 Fiesta Workshop Manual
Procedure revision date: 08/18/2010
Preliminary Inspection
Determine Customer Concern
Determine customer concerns relative to vehicle use and dependent driving conditions, paying attention
to the following items:
Hot or cold vehicle operating temperature
Hot or cold ambient temperatures
Type of terrain
Vehicle loaded/unloaded
City/highway driving
Upshift
Downshift
Coasting
Engagement
Noise/vibration — check for dependencies, either rpm dependent, vehicle speed dependent, shift
dependent, gear dependent, range dependent or temperature dependent.
Transmission Fluid Level and Condition Check
NOTICE: If transaxle noise is reported, first check the transmission fluid level. The vehicle
should not be driven if the transmission fluid level is low or damage can occur.
NOTE: The vehicle should not be driven if the transmission fluid level is low.
An incorrect transmission fluid level may affect the transaxle operation and can result in transaxle
damage. To correctly check and add transmission fluid to the transaxle, refer to Transmission Draining
and Filling in this section.
A low transmission fluid level can result in poor transaxle shifting, engagement or damage. It can also
indicate a leak in the transaxle seals.
1. Check the transmission fluid condition.
Observe the color of the transmission fluid. Allow the transmission fluid to drip onto a white
cloth and examine the stain. Check the transmission fluid for contamination or metal
particles.
Transmission fluid should appear nearly clear.

Evaluation of the Transaxle
1. During the road test, use the following driving methods to diagnose the problem.
Start the engine.
Evaluate the noise in NEUTRAL while the vehicle is parked.
Check whether the noise is present.
With the parking brake engaged, move the selector lever to DRIVE. Apply very
slight pressure to the throttle and note if the noise level is reduced.
With the vehicle in PARK, check whether the noise is present as the engine speed
is increased. If the noise reduces, note the engine speed at which this occurs.
Listen for any change in noise while changing engine rpm.
Drive the vehicle and allow it to shift through all of the gear ranges, including reverse.
Listen for any change in noise in a particular gear.
Drive the vehicle in the gear in which the noise is most noticeable. Listen for any change in
noise.
Drive the vehicle in the gear in which the noise is most noticeable and shift the transaxle
into NEUTRAL. Allow the vehicle to coast. Note any change in noise.
2. Compare the road test results with the symptom charts. It is a list of conditions that are typical
faults into which the transaxle will fall:

Information
DESCRIPTION AND OPERATION
2011 Fiesta Workshop
Manual
Procedure revision date:

Manual Transaxle and Clutch
The IB5 manual transaxle and clutch system consists of the following:
Five-speed manual transaxle
Clutch disc
Clutch pressure plate
Clutch release hub and bearing
Clutch hydraulic system
Clutch pedal
Flywheel
The function of the transaxle is to move the vehicle from a rest position to motion. The transaxle uses
gears to adapt the torque to the demands of load and road conditions. It matches engine power to
vehicle needs. This power is delivered from the engine flywheel to the transaxle. The power is
transmitted through a driver-operated clutch, which allows for engagement and disengagement of the
engine to the transaxle.
The transaxle input shaft receives the power when the clutch is engaged. The transaxle then uses a
system of gears to change the speed and torque relationship between the engine crankshaft and the
transaxle differential.
The purpose of the clutch is to connect and disconnect a manually operated transaxle and the halfshafts
from the engine. This allows starting and stopping the vehicle, shifting and changing speeds that
correspond to the engine speed through gear changes.

Inspection and Verification
NOTICE: If transaxle noise is reported, check the fluid level first. Do not drive the vehicle if the
fluid level is low or damage can occur.
NOTE: If any evaluation or inspection reveals an obvious concern, repair the vehicle.
NOTE: Before attempting to repair any concerns, road test the vehicle to determine in which system the
concern falls.
The technician should have a thorough knowledge of transaxle/clutch operation and accepted general
transaxle/clutch guidelines to detect any problems.
A gear driven unit produces a certain amount of noise. Some noise is acceptable and audible at certain
speeds or under various driving conditions. Certain conditions, such as road and weather, amplify
normal vehicle noise.
Use the following to diagnose and repair a transaxle/clutch concern:
Verify the Customer Concern
NOTICE: If transaxle noise is reported, first check the fluid level. The vehicle should not be
driven if the fluid level is low or damage can occur.
1. Verify and document the customer concern.
1. When was it first noticed?
2. Did it appear suddenly or gradually?
3. Did anything unusual occur that would coincide with it or precede it?
4. Identify when the condition occurs.
Hot or cold vehicle operating conditions
Type of terrain
City or highway driving
Driving at a particular speed
coasting
hard acceleration
Shifting
upshifts
downshifts
in a particular gear
in all gears
Hot or cold ambient temperatures
5. Check TSBs and On-Line Automotive Service Information System (OASIS) messages.
2. Visually inspect for obvious signs of mechanical damage.
Check Fluid Level and Condition
NOTICE: Do not drive the vehicle if the fluid level is low or damage can occur.
An incorrect fluid level may affect transaxle operation and can result in transaxle damage. To correctly
check and add fluid to the transaxle, refer to transaxle draining and filling in Section 308-03 .
Low fluid level can result in poor transaxle shifting, engagement or damage. It can also indicate a leak in
one of the transaxle seals or gaskets.
1. Check the fluid condition.
Observe the color and the odor of the fluid. Allow the fluid to drip onto a white cloth and
examine the stain. Check the fluid for contamination or metal particles.
Fluid should appear nearly clear, similar to clean engine oil.
Evaluation of Clutch Hydraulic System
1. Verify the clutch hydraulic fluid reservoir is filled to the correct level.
If the fluid level is low, add fluid as necessary. Check the clutch hydraulic system for leaks
and repair as necessary. Refer to Section 308-02 .
Evaluation Of The Clutch
1. Slowly press and release the clutch pedal to see if the pedal is binding. Make sure the clutch
pedal can be fully pressed and is not restricted by the floor mat. Verify the pedal return spring is
present and is functioning correctly.
2. Measure the clutch reserve. GO to Pinpoint Test A .
3. With the engine idling, the parking brake on and the clutch pedal up, gently move the gearshift
lever into a forward or reverse gear, until gear clash can be heard. Slowly press the clutch pedal.
If the gears cease to clash (full disengage at 25-38 mm [1-1.5 in] from the floor), hold the
pedal at the point of disengagement and increase engine to 4,000 rpm. If the clutch
remains disengaged, it is functioning correctly.
Any concerns indicate a worn or damaged clutch. Repair as necessary. Refer to Section
308-01 .
4. With the engine idling, move the gearshift lever into 4th gear. Increase the engine to 2,000 rpm
and slowly release the clutch pedal.
If the engine stalls, the clutch is OK.
If the engine does not stall, the clutch is slipping. Repair as necessary.
5. Compare the road test results with the symptom chart. The chart is a list of conditions that are
typical faults. GO to Symptom Chart - Clutch .
Inspect The Gearshift Components
1. Inspect the gearshift cables for:
signs of damage
broken locks
binding
cables not fully seated or in hold-down brackets
correct routing
correct adjustment
If the concern is a gear(s) cannot be selected, jumps out of gear or gear clashes,
adjust the gearshift cables. Refer to Section 303-06 .
2. Inspect the gearshift lever for free play.
If the gearshift lever free play is more than 15 mm (0.59 in), check the gearshift cables and
repair as necessary.
If the gearshift lever free play is 15 mm (0.59 in), adjust the gearshift cables. Refer to
Section 308-06 .
Road Test the Vehicle
1. During the road test, use the following driving methods to diagnose the problem.
Start the engine.
Evaluate the noise in NEUTRAL while the vehicle is parked.
Check whether the noise is present with the clutch fully disengaged (pedal fully
pressed). Check to see if the pedal pulsates abnormally (for clutch diaphragm finger
run out).
Check whether the noise is present with the gearshift in the NEUTRAL position and
the clutch fully engaged (foot off pedal). With the parking brake engaged, move the
gearshift towards the 1st gear position. Apply very slight pressure and note if the
gear noise level is reduced (for gear rollover noise).
With the clutch fully engaged (foot off pedal) check whether the noise is present as
the engine rpm increases. If the noise reduces, note the engine rpm at which this
occurs.
Listen for any change in noise while pressing and releasing the clutch pedal.
Listen for any change in noise while changing the engine rpm.
Drive the vehicle and shift through all of the gear ranges, including reverse. Listen for any
change in noise in a particular gear.
Drive the vehicle in the gear in which the noise is most noticeable. Press the clutch pedal
and leave the gear engaged. Listen for any change in noise.
Drive the vehicle in the gear in which the noise is most noticeable. Press the clutch pedal
and shift the transaxle into NEUTRAL. Release the clutch pedal and allow the vehicle to
coast.
2. Compare the road test results with the symptom charts. The charts are a list of conditions that are
typical faults.GO to Symptom Chart - Clutch , GO to Symptom Chart - Transaxle or GO to

The clutch transmits the engine torque to the transaxle.
The clutch is a single-plate, dry-friction disc with a diaphragm-style spring clutch pressure plate. The
clutch disc has a hub which is splined to the transmission input shaft. The clutch disc has friction
material where it contacts the flywheel and the clutch pressure plate. The clutch pressure plate applies
pressure to the clutch disc, holding it tightly against the surface of the flywheel. In the engaged position,
the diaphragm spring holds the clutch pressure plate against the clutch disc, so that engine torque is
transmitted to the input shaft.
When the clutch pedal is applied, the release bearing pushes the diaphragm spring center of the clutch
pressure plate toward the flywheel. The diaphragm spring pivots at the fulcrum, relieving the load on the
clutch pressure plate. The clutch slave cylinder assists in the effort it takes to relieve the load on the
clutch pressure plate. Steel spring straps riveted to the clutch pressure plate cover pull the clutch
pressure plate from the clutch disc, disengaging the engine torque from the transaxle.

Clutch slave cylinder
The clutch control system is a hydraulic/mechanical clutch system. The clutch control system disengages the
clutch when the clutch pedal is pressed and engages the clutch when the clutch pedal is released. When the
clutch pedal is pressed, pressure builds up in the clutch master cylinder and the release bearing in the clutch
slave cylinder is actuated.
The advantages of a hydraulic clutch system are:
Automatic adjustment
Low operating effort
Minimal wear
A self-adjusting clutch system eliminates the need for maintenance adjustments. It provides for consistent pedal
height throughout the service life of the clutch.
Brake Fluid Reservoir
The brake fluid reservoir supplies brake fluid to the hydraulic clutch system and the brake system. The
hydraulic clutch system and brake system are arranged separately inside the brake fluid reservoir. If a leak
occurs in the hydraulic clutch system, the brake system continues to operate unrestricted.
Brake Fluid Filling Reservoir
The brake fluid filling reservoir is remotely attached to the brake fluid reservoir. Due to the brake fluid reservoirs
location the brake fluid filling reservoir allows the technician to easily fill the brake fluid reservoir.
Clutch Master Cylinder
The clutch master cylinder generates the system pressure required to actuate the clutch. When the clutch pedal
is depressed, the piston rod moves the clutch master cylinder piston. The hydraulic fluid in the clutch master
cylinder is forced through the high-pressure tube to the clutch slave cylinder.
Clutch Pedal
When the clutch pedal is pressed, the clutch master cylinder transmits hydraulic fluid pressure to the clutch
slave cylinder. The clutch slave cylinder and the clutch release fork transfer the clutch pedal motion to the
clutch release bearing. The release bearing presses against the pressure plate diaphragm spring, releasing the
clutch disc. Once the clutch pedal is released, the diaphragm spring pushes the piston in the clutch slave
cylinder back to its initial position. The non-positive connection between the clutch disc and the flywheel is reestablished.
Clutch Slave Cylinder
The central clutch slave cylinder is equipped with a release bearing and is attached to the clutch bell housing
with three bolts. The release bearing is an interference installed in the clutch slave cylinder and is not serviced
separately.
The hydraulic fluid forced from the piston in the clutch master cylinder moves the piston in the clutch slave
cylinder which, moves the release bearing in an axial direction. The release bearing inner ring presses onto the
diaphragm spring. The non-positive connection between the clutch disc and the flywheel is interrupted.

The IB5 transaxle has an aluminum transaxle housing which comprises of two sections. Its rigidity has been
improved with the inclusion of reinforcement ribbing in the design. The transaxle housing sections come in pairs
and cannot be obtained separately. The clutch is hydraulically actuated.
All the gears are constant mesh gears (except reverse gear). In each gear, the required transaxle ratio is
achieved by means of a pair of gears.
When reverse gear is selected, the direction of rotation of the output shaft is changed by an idler gear.
The gears are all helical gears (except reverse gear). They all have synchronizers (except reverse gear) and
run on plain bearings.
First and second gears have dual synchronizers.

Synchronizer assembly
Dual Synchronizer
First and second gear have dual synchronizers. The use of a second synchronizer ring means that the effective
synchronization area is increased approximate. 100% in relation to single synchronizers. Dual synchronization
gives considerable improvement in gearshift quality.
The dual synchronizers consist of inner synchronizer ring, cone ring, outer synchronizer ring and synchronizer
assembly.
The conical surface on the gear wheel is discontinued. Synchronization occurs through both synchronizer rings
and the cone ring which is positively fitted to the gear wheel.
Differential
Major components of the differential include:
Differential ring gear
Differential housing with two taper roller bearings
Differential pinion gears
Input shaft pinion gears
The transaxle and differential are housed in a two-section aluminum housing and flange-mounted to the engine.
The input torque is transmitted to the differential via a ring gear which is bolted to the differential case.
The differential case contains the differential pinions mounted on one pin as well as the front halfshaft pinions
connected to the front drive shafts through the splines.
If the front wheels are travelling at different speeds (when cornering), the front halfshaft pinions can move on
the differential pinions.

Reverse idler gear
The reverse idler gear is driven off the input shaft. Its purpose is to change the direction of rotation of the output
shaft when reverse gear is selected.
The reverse idler gear runs in a plain bearing on the idler gear shaft and a bearing block.
The selector interlock mechanism and the selector finger are mounted on a sleeve in the transaxle housing.
They hold the selected gear by means of a spring-loaded ball until a different gear is selected.
The selector interlock mechanism has three different positions.

The manual transaxle is controlled by a floor-mounted gearshift lever located in the floor console. Connection
between the floor-mounted gearshift lever and the transaxle shift lever and selector lever is made through 2
gearshift cables. When the operator moves the floor mounted gearshift lever, that movement is transmitted
through 2 gearshift cables routed through the floor to the transaxle. The 2 gearshift cables are attached to the
transaxle at the shift lever and selector lever. The shift and selector levers transfer the movement of the
gearshift cables to the shift rods and shift forks located inside the transaxle. Removal and installation of the
gearshift cables require specific adjustments for correct shifting of the transaxle. For information regarding
gearshift cable adjustments, refer to Section 308-00 .

SECTION 309-00: Exhaust System
DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Exhaust System
The exhaust system consists of:
a one-piece catalytic converter manifold with exhaust flexible pipe.
a resonator.
a muffler and tailpipe assembly with isolators.
The exhaust system provides an exit for exhaust gases and reduces engine noise by passing exhaust
gases through the catalytic converter, a muffler and tailpipe assembly and resonator. Rubber exhaust
hanger isolators attach the exhaust system to the mounting hooks on the body.
Catalytic Converter
The catalytic converter plays a major role in the emission control system by functioning as a gas reactor.
The catalytic converter speeds up the heat producing chemical reaction between the components of the
exhaust gases to reduce air pollutants. Due to the high temperatures at which the catalytic converter
operates, the vehicle body areas around the catalytic converter are protected by heat shields. The
catalytic converter controls Hydrocarbon (HC), Carbon Monoxide (CO) and Nitrogen Oxides (NOx)
emissions.

DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Fuel System
The fuel system consists of:
a Multi-Port Fuel Injection (MFI) system.
a 2-speed Mechanical Returnless Fuel System (MRFS).
Easy Fuel TM (capless) fuel tank filler pipe assembly.
a fuel tank filler pipe containing:
a recirculation tube.
a fresh air hose.
a restrictor plate to permit only unleaded fuel to be pumped into the tank.
a fuel tank.
a Fuel Pump (FP) module containing:
an electric FP , which provides pressurized fuel to the fuel rail.
a lifetime fuel filter serviced as part of the FP module.
a serviceable fuel level sender.
a check valve, which maintains system pressure after the FP is shut off.
a pressure relief valve for overpressure protection in the event of restricted fuel flow.
fuel, vapor and brake tubes in an integrated bundle assembly attached to the underside of the
vehicle by retaining clips.
a fuel rail.
fuel injectors.
fuel pump control module.
The fuel tank filler pipe cannot be modified in any way.
The vehicle is equipped with electronic Multi-Port Fuel Injection (MFI) that is supplied by a 2-speed
Mechanical Returnless Fuel System (MRFS) . The PCM is able to maintain constant fuel pressure by
varying the FP output. This is accomplished by increasing or decreasing voltage supplied by the fuel
pump control module to the FP based on the duty cycle request from the PCM. The returnless fuel
system offers improved economy, lower fuel temperatures and decreased fuel vapor in the fuel tank.
Fuel Pump (FP) Shut-off Feature
In the event of a moderate to severe collision, the vehicle is equipped with a Fuel Pump (FP) shut-off
feature that is initiated by the event notification signal.
The event notification signal is a signal provided by the Restraints Control Module (RCM) to the FP
control module. Signal communication between the RCM and the FP control module allows the PCM to
shut-off the FP .
Should the vehicle shut off after a collision due to this feature, the vehicle may be restarted by first
turning the ignition switch to the OFF position and then turn the ignition switch to the ON position. In
some instances the vehicle may not start the first time and may take one additional key cycle.

Principles of Operation
NOTE: The following procedure diagnoses a slow to fill concern only. For all other concerns, refer to the
Powertrain Control/Emissions Diagnosis (PC/ED) manual.
The fuel tank filler pipe assembly is used to refuel the vehicle. The fuel tank inlet check valve prevents
spitback of fuel during and after refueling. The fuel tank stores the fuel. The fuel tank contains a Fuel
Pump (FP) module. The FP module consists of a fuel level sender and a FP . The fuel level sender
sends a signal to the fuel gauge informing the driver of how much fuel is in the fuel tank. The FP
provides fuel to the fuel tubes, which supply the fuel rail.
During refueling, the fuel tank vents to the atmosphere through the vent and filler pipes, on vehicles
without On-Board Refueling Vapor Recovery (ORVR) systems. In vehicles equipped with ORVR , the
fuel tank and filler pipe are designed so that when the vehicle is being refueled, fuel vapors in the fuel
tank travel to the Evaporative Emission (EVAP) canister, which absorbs the fuel vapors and vents the
pressure from the fuel tank during refueling.
Inspection and Verification
WARNING: Do not smoke, carry lighted tobacco or have an open flame of any type when
working on or near any fuel-related component. Highly flammable mixtures are always present
and may be ignited. Failure to follow these instructions may result in serious personal injury.
WARNING: Do not carry personal electronic devices such as cell phones, pagers or audio
equipment of any type when working on or near any fuel-related component. Highly flammable
mixtures are always present and may be ignited. Failure to follow these instructions may result

SECTION 310-01: Fuel Tank and Lines
DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 04/07/2011
Fuel Tank and Lines
The fuel system consists of:
a Multi-Port Fuel Injection (MFI) system.
a 2-speed Mechanical Returnless Fuel System (MRFS).
Easy Fuel TM (capless) fuel tank filler pipe assembly.
a fuel tank filler pipe containing:
a recirculation tube.
a fresh air hose.
a restrictor plate to permit only unleaded fuel to be pumped into the tank.
a fuel tank.
a Fuel Pump (FP) module containing:
an electric FP , which provides pressurized fuel to the fuel rail.
a lifetime fuel filter serviced as part of the FP module.
a serviceable fuel level sender.
a check valve, which maintains system pressure after the FP is shut off.
a pressure relief valve for overpressure protection in the event of restricted fuel flow.
fuel, vapor and brake tubes in an integrated bundle assembly attached to the underside of the
vehicle by retaining clips.
a fuel rail.
fuel injectors.
fuel pump control module.
The fuel tank filler pipe cannot be modified in any way.
The vehicle is equipped with electronic Multi-Port Fuel Injection (MFI) that is supplied by a 2-speed
Mechanical Returnless Fuel System (MRFS) . The PCM is able to maintain constant fuel pressure by
varying the FP output. This is accomplished by increasing or decreasing voltage supplied by the fuel
pump control module to the FP based on the duty cycle request from the PCM. The returnless fuel
system offers improved economy, lower fuel temperatures and decreased fuel vapor in the fuel tank.
Fuel Pump (FP) Shut-off Feature
In the event of a moderate to severe collision, the vehicle is equipped with a Fuel Pump (FP) shut-off
feature that is initiated by the event notification signal.
The event notification signal is a signal provided by the Restraints Control Module (RCM) to the FP
control module. Signal communication between the RCM and the FP control module allows the PCM to
shut-off the FP .
Should the vehicle shut off after a collision due to this feature, the vehicle may be restarted by first
turning the ignition switch to the OFF position and then turn the ignition switch to the ON position. In
some instances the vehicle may not start the first time and may take one additional key cycle.

Steering System
Electronic Power Assist Steering (EPAS) System
NOTICE: The steering sensor contains a clockspring that will be damaged if the steering column
is not handled correctly. To prevent damage to the steering sensor, use the service bolt (HB1) to
lock the steering column in the straight ahead position before disconnecting the steering column
from the steering gear. Damage caused to the steering sensor by failing to lock the steering
when disconnecting the column from the steering gear leads to a complete failure of the
Electronic Power Assist Steering (EPAS) system and requires a new EPAS column to be
installed.
The Electronic Power Assist Steering (EPAS) system consists of the following components:
Power Steering Control Module (PSCM) — the PSCM controls the functions of the EPAS system
and communicates with other modules on the High Speed Controller Area Network (HS-CAN).
The PSCM is attached to the EPAS column assembly and cannot be serviced separately.
Motor — the EPAS column uses a 12-volt brushless, reversible motor, a worm gear and a
reduction gear to control the steering effort. The motor is attached to the EPAS column assembly
and cannot be serviced separately.
Steering sensor — the PSCM uses the steering sensor to determine force applied to, speed and
direction of the steering wheel. This information is transmitted to other modules along the HSCAN . The sensor is attached to the EPAS column assembly and cannot be serviced separately.
Steering column shaft — the steering column shaft connects the EPAS column assembly to the
steering gear and can be serviced separately. For additional information, refer to Section 211-04 .
Steering gear — the steering gear is a rack and pinion type gear, which is serviced as an
assembly and contained within a one-piece aluminum housing. The steering gear uses tie-rod
ends to connect the gear to the wheel knuckles. The steering gear can be serviced separately
from the EPAS column assembly. For additional information, refer to Section 211-02 .
Tie-rod ends — one inner and outer tie rod is located at each end of the steering gear and can be
serviced separately. For additional information, refer to Section 211-02 .
The EPAS system provides power steering assist to the driver by replacing the conventional hydraulic
valve system with an electric motor coupled to the steering shaft. The motor is controlled by the PSCM
which senses the steering effort using sensors mounted between the steering column shaft and the
steering gear. Steering assist is provided in proportion to the steering input effort and vehicle speed.

Principles of Operation
Electronic Power Assist Steering (EPAS)
The Electronic Power Assist Steering (EPAS) system provides power steering assist to the driver by
replacing the conventional hydraulic valve system with an electric motor coupled to the steering shaft.
The motor is controlled by the Power Steering Control Module (PSCM) that senses the steering effort
using a torque sensor mounted internally to the steering column assembly. Steering assist is provided in
proportion to the steering input effort and vehicle speed.
The EPAS system requires a 12-volt, hot at all times feed for system operation. The PSCM is activated
when power is applied to the hardwired ignition/run input. After activation, the PSCM monitors the High
Speed Controller Area Network (HS-CAN) to determine if the vehicle is operating in a manner capable of
supporting the EPAS system.
The PSCM recieves vehicle speed from the PCM over the HS-CAN and steering shaft speed, direction
and position from the steering shaft sensor to determine the amount or level of power steering assist
provided by the EPAS system.
The level of steering assist is primarily based on vehicle speed. As vehicle speed increases, the amount
of assist decreases to improve and enhance road feel at the steering wheel. As vehicle speed decreases
the amount of assist increases to ease vehicle maneuvering. If the vehicle speed is missing or out of
range, the PSCM defaults to a safe level of assist for all driving conditions. If the vehicle speed returns to
the correct in-range values, the PSCM adjusts the level of assist accordingly. Steering wheel/shaft
speed, torque and direction information allows the PSCM to determine how much assist is needed to
turn the wheels right and left.
The PSCM continually monitors and adjusts steering efforts based on the sensor inputs to enhance the
feel of the steering. Compensation is made to reduce the effect of pull or drift that may be experienced
when driving on roads with a high degree of camber. Active nibble control is also employed by the
PSCM to reduce the vibrating movement felt at the steering wheel that can be caused by driving on
rough surfaces or out of balance wheels.
The PSCM is self-monitoring and is capable of setting and storing DTCs. Depending on the DTC set, the
control module enters into a safe mode of manual steering. In addition, the PSCM may send a request to
the Instrument Panel Cluster (IPC) module over the HS-CAN to display a message in the message
center, part of the Front Controls Interface Module (FCIM) alerting the driver of a potential EPAS
concern.
Low battery and/or charging system voltage or a charging system DTC being present may cause the
PSCM to enter into a limited operation mode resulting in uneven steering assist or a lack of steering
assist. This limited operation mode feature is built into the PSCM to allow the safe, continued operation
of the vehicle in the event of an EPAS concern. A DTC may or may not be present when the PSCM is
operating in limited operation mode. Additionally, overheating the steering system may cause the PSCM
to go into the limited operation mode, to protect the electronic components from overheating.
The PSCM is an integral part of the EPAS column assembly and cannot be serviced separately.
Power Steering Control Module (PSCM) Power Down
The internal circuitry of the PSCM enables the PSCM to remain powered for 90 seconds after the igniton
state has been switched to OFF. When carrying out diagnostic procedures that require DTCs to be
cleared and a new ignition cycle to be started, make sure the ignition state remains OFF for a minimum
of 90 seconds before switching to ON. This allows the PSCM to shut down completely and a new
ignition cycle to be entered.
Power Steering Motor
The EPAS system uses a 12-volt brushless reversible motor to control the steering effort. The motor is
connected to the steering shaft through a worm gear and a reduction gear on the steering column. The
motor is part of the steering column assembly and is not serviced separately.
Steering Sensor
NOTICE: The steering sensor contains a clockspring that will be damaged if the steering column
is not handled correctly. To prevent damage to the steering sensor, use the service bolt (HB1) to
lock the steering column in the straight ahead position before disconnecting the steering column
from the steering gear. Damage caused to the steering sensor by failing to lock the steering
when disconnecting the column from the steering gear leads to a complete failure of the EPAS
system and requires a new EPAS column to be installed.
The steering sensor provides the PSCM with information on the direction, speed and amount of force
being applied to the steering wheel. The steering sensor is a split sensor that monitors the steering
inputs from the driver and the output side of the EPAS assembly. The PSCM uses the inputs from the
sensor to determine the amount of steering assist required and adjusts steering efforts based on the
sensor inputs. The sensor is a 5-volt dual analog sensor with an output voltage range of 0.25 volt to 4.75
volts. When the steering wheel is turned to the left, the left signal increases while the right signal
decreases, likewise when the steering wheel is turned to the right, the right signal increases while the
left signal decreases.

DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Steering Column
The steering column is the mechanical linkage between the steering wheel and the steering gear.
However, the steering column housing also contains the Power Steering Control Module (PSCM), motor
and steering sensor, which are used to provide the power assist. The programmable module uses inputs
from the sensor to determine when and how much assist is needed. The 12-volt brushless, reversible
motor uses a worm gear and a reduction gear to apply the power assist to the steering column shaft.
The steering column, module, motor and sensor are serviced as an assembly. For information on
Electronic Power Assist Steering (EPAS) diagnosis, refer to Section 211-00 .
The steering wheel is mounted to a shaft which passes through the center of the steering column. The
shaft is centered by roller ball bearings within the steering column. The steering column shaft then
connects the steering column to the steering gear. The upper and lower steering column shaft
connections utilize U-joint type couplings. The tilt function of the steering column is controlled by a
mechanical lever on the underside of the steering column which uses a cam to lock and unlock the
steering column. When the tilt lever is unlocked, the steering column can then be adjusted to various
positions through a pin-type pivot. The steering column switches (multifunction and ignition) are mounted
to the steering column. These switches are covered by the upper and lower steering column shrouds.
For information on steering column switches, refer to Section 211-05 .

Principles of Operation
Ignition Switch
The ignition switch is controlled by the ignition lock cylinder with a key. When the ignition lock cylinder is
turned, a mechanical connection positions the ignition switch to the selected position. The available
ignition switch positions are:
OFF
ACC
ON
START
The ignition switch supplies battery voltage to the Central Junction Box (CJB) which then distributes this
voltage to multiple circuits and modules throughout the vehicle, based on ignition switch position.
Push Button Start System
The Remote Function Actuator (RFA) module applies battery voltage to the same circuits that a
conventional ignition switch uses to achieve 3 of the 4 standard ignition states (OFF, ON and START).
Unlike a conventional ignition switch system, this push button start system does not have a driver
accessible ACC mode. The RFA module automatically cycles through the ACC mode when the driver
cycles the vehicle to the ON mode. The RFA module receives input from the following:
Clutch Pedal Position (CPP) switch (manual transaxle)
Cruise control deactivator switch (automatic transaxle)
Intelligent Access (IA) key (wireless input)
Park detect switch (automatic transaxle)
Start/stop switch
The RFA module uses input from the IA key to authorize use of the vehicle. The RFA module uses input
from the start/stop switch, the park detect switch (automatic transaxle), the cruise control deactivator
switch (automatic transaxle) and/or the CPP switch (manual transaxle) to transition between ignition
modes.
Intelligent Access (IA) Key
To achieve any ignition state other than OFF, the IA key must be present inside the vehicle. The driver
need not perform any actions with the IA key to operate the push button start system. It is sufficient that
the IA key is located inside the vehicle when the start/stop switch is pressed. Pressing the start/stop
switch triggers radio frequency communication between the IA key and the RFA module.
Backup Antenna
If the battery inside the IA key is weak, if the IA key is damaged or if excessive ambient Radio
Frequency Interference (RFI) prevents communication between the RFA module and the IA key, the
backup antenna located on the RH side of the steering column (where a conventional ignition lock
cylinder would be located) provides a secondary means for the RFA module to validate the IA key and
authorize use of the vehicle. The backup antenna uses passive radio frequency identification to
exchange signals with the IA key, similar to the way a typical encoded Passive Anti-Theft System
(PATS) key and transceiver operate. For additional information on the IA key and backup antenna, refer
to Section 419-01B .
Push Button Start System Front Control/Display Interface Module (FCDIM) Messages
The FCDIM provides instruction for operating the push button start system. The FCDIM can also display
warnings that could indicate a potential issue with the push button start system. The following FCDIM
messages pertain to the push button start system:
TO START PRESS BRAKE — Momentarily displays when the start/stop switch is pressed
without the brake pedal being applied (vehicles equipped with an automatic transaxle).
TO START PRESS CLUTCH — Momentarily displays when the start/stop switch is pressed
without the clutch pedal being applied (vehicles equipped with a manual transaxle).
TO START SELECT N OR P — Displays when attempting to start the vehicle and the transaxle is
not in NEUTRAL or PARK (vehicles equipped with an automatic transaxle).
VEHICLE NOT IN PARK SELECT P — Displays when the start/stop switch is pressed to shut off
the engine with the transaxle selector lever in any position other than PARK (vehicles equipped
with an automatic transaxle).
KEY OUTSIDE CAR — Whenever a door is opened and then closed while the engine is running,
the RFA module searches for the IA key. This message displays if the key is not detected by the
module.
KEY NOT DETECTED — Displays if the IA key is not detected by the RFA module when
attempting to enter ON mode or attempting to start the vehicle. If this message is observed with
the IA key located inside the vehicle, go to Section 419-01B to diagnose the IA key.
Remote Function Actuator (RFA) Module Programming
If it is necessary to replace the RFA module, the replacement module must be programmed. Carry out
the following scan tool functions if an RFA module is installed new:
NOTE: All of the following scan tool functions must be completed before the vehicle will start.
Programmable Module Installation (PMI) — This process configures the new module with specific
vehicle information. Refer to Programmable Module Installation (PMI) in Section 418-01 .
PATS Parameter Reset — This process initiates an exchange of information between the RFA
module and the PCM specific to the anti-theft/engine immobilizer feature. Carry out a PATS
parameter reset when either the RFA module or the PCM is installed new. For additional
information, refer to Passive Anti-Theft System (PATS) Parameter Reset-Intelligent Access (IA) in
Section 419-01B .
IA Key Programming — This process programs the IA keys to the RFA module. If the RFA
module is installed new, 2 IA keys will have to be programmed before the vehicle will start. For
additional information, refer to Key Programming Using Diagnostic Equipment-Intelligent Access
(IA) in Section 419-01B .
Multifunction Switches
The multifunction switches control the various components (high beam headlamps, flash-to-pass, turn
signal, trip computer display and windshield wiper/washer) by grounding certain Body Control Module
(BCM) or Instrument Panel Cluster (IPC) circuits. When the BCM or IPC detects the ground signal,
voltage is sent to activate the appropriate component. The BCM controls the high beam headlamps,
flash-to-pass, turn signals and windshield wipers/washers. The IPC controls the trip computer display.
For multifunction switch concerns, refer to one of the following sections:
For high beam headlamps, flash-to-pass and turn signal concerns, refer to Section 417-01 .
For wiper and washer concerns, refer to Section 501-16 .
For trip computer concerns, refer to Section 413-01 .
Inspection and Verification
NOTE: Make sure the vehicle battery is fully charged and in good condition before diagnosing any
ignition switch concerns.

Pinpoint Test E: DTCs B108B:23, 29 and B108C:23
Refer to Wiring Diagrams Cell 20 , Starting System for schematic and connector information.
Normal Operation
The start stop/switch is a momentary, dual-contact, normally-open switch. This means that the 2 internal
contacts will only remain closed for as long as the switch is pressed. As soon as the switch is released,
the contacts will open. The start/stop switch is connected to the Remote Function Actuator (RFA)
module by 2 circuits. When the switch is pressed, both contacts close and connect to a ground circuit.
The RFA module detects this ground signal and enters into 1 of the 3 ignition modes, depending on
other RFA module inputs. The start/stop switch uses 2 sets of contacts and 2 circuits for redundancy; if
there is a concern in one of the 2 circuits/contacts, the other can still provide a ground signal to the RFA
module. Also, if there is a concern in one of the 2 circuits/contacts, the RFA module sets one or more
DTCs.
DTC B108B:23 (Start Button Circuit "A": Signal Stuck Low) — Pressing the start/stop switch starts
a 120 second timer in the RFA module. This DTC sets if the signal from circuit "A" is still present
when the timer expires. Pressing and holding the start/stop switch for more than 120 seconds
also causes this DTC to set. This DTC only sets during normal operation and not during a module
self-test.
DTC B108B:29 (Start Button Circuit "A": Signal Invalid) — Pressing and releasing the start/stop
switch causes both internal contacts to change state (open to closed and then closed to open) at
the same time. The RFA module detects this change in state and increases an internal counter by
1 if the change does not happen at the same time or if only one of the contacts changes state.
When the internal counter reaches 5, the RFA module sets this DTC. This DTC only sets during
normal operation and not during a module self-test.
DTC B108C:23 (Start Button Circuit "B": Signal Stuck Low) — Pressing the start/stop switch starts
a 120 second timer in the RFA module. This DTC sets if the signal from circuit "B" is still present
when the timer expires. Pressing and holding the start/stop switch for more than 120 seconds
also causes this DTC to set. This DTC only sets during normal operation and not during a module
self-test.

Pinpoint Test F: DTCs B10E7:11, 12, 16 and 17
Refer to Wiring Diagrams Cell 13 , Power Distribution for schematic and connector information.
Normal Operation
The Remote Function Actuator (RFA) module controls and monitors the coil side of the smart keyless
entry ignition relay. When the RFA module enters ON mode, it activates the relay. When energized, the
relay sends power to the Central Junction Box (CJB), the main ignition relay and back to the RFA
module. The RFA module uses this voltage input for diagnostic purposes.

Normal Operation
To place the vehicle in ON mode, place the Intelligent Access (IA) key inside the vehicle and press the
start/stop switch for at least one second without applying the brake pedal (or clutch pedal if equipped
with a manual transmission). When in ON mode, the Remote Function Actuator (RFA) module applies
battery voltage to the coil side of the smart keyless entry ignition relay and the smart keyless entry
accessory relay. When activated, the smart keyless entry ignition relay provides battery voltage to the
main ignition relay and several fuses in the Central Junction Box (CJB). The main ignition relay provides
power to various vehicle systems. When activated, the smart keyless entry accessory relay provides
battery voltage to CJB fuses 19 (7.5A) and 26 (7.5A).
To start the engine; place the IA key inside the vehicle, shift the transaxle into PARK (automatic
transaxle) or NEUTRAL (automatic or manual transaxle), place the vehicle in either OFF mode or ON
mode, press and hold the brake pedal (automatic transaxle) or clutch pedal (manual transaxle), then
press the start/stop switch.
At that time, the RFA module sends a voltage signal to the input side of the starter inhibit relay coil. If the
Passive Anti-Theft System (PATS) authorizes the system to start the engine, the PCM supplies a ground
to the coil of the starter inhibit relay, closing the relay and engaging the starter motor.
In the event the vehicle will not enter ON or START mode, the Front Control/Display Interface Module
(FCDIM) displays messages that may indicate possible causes.

Refer to Wiring Diagrams Cell 13 , Power Distribution for schematic and connector information.
Refer to Wiring Diagrams Cell 20 , Starting System for schematic and connector information.
Normal Operation
The Remote Function Actuator (RFA) module receives a direct input from the start/stop switch. After
receiving this input, the RFA module activates the smart keyless entry ignition relay, the smart keyless
entry accessory relay and the main ignition relay. The Instrument Panel Cluster (IPC) receives power
from the 2 smart keyless entry relays and sends an ignition status message to the RFA module over the
Controller Area Network (CAN), the RFA module uses this status message as a way to self-test.

Fault Trigger Condition
One or more of these DTCs are set if the IPC ignition status message
received by the RFA module does not match the start/stop switch input to the
RFA module. This can be caused by a communication issue between the IPC
and the RFA module, a wiring concern in the CAN , a wiring concern in the
ignition input to the RFA module, a wiring concern in the relay inputs to the
IPC , a failure of the start/stop switch or a failure in either module. The input
from the start/stop switch to the RFA module supersedes the input message
from the IPC .

Climate Control System
Climate Control System Operation
WARNING: Take the following precautions when repairing an air conditioning system
containing R-134a:
Always wear safety goggles.
Avoid contact with liquid refrigerant R-134a. R-134a vaporizes at approximately -25°C (-13°
F) under atmospheric pressure and will freeze skin tissue.
Never allow refrigerant R-134a gas to escape in quantity in an occupied space. It will
displace the oxygen needed to support life.
Never use a torch in an atmosphere containing R-134a gas. R-134a is non-toxic at all
normal conditions, but it decomposes when exposed to high temperatures such as a torch
flame. During decomposition it releases irritating and toxic gasses (as described in the
MSDS sheet from the manufacturer). Decomposition products are hydrofluoric acid,
carbon dioxide and water.
Failure to follow these instructions may result in serious personal injury.
NOTICE: To avoid damaging the vehicle or Air Conditioning (A/C) components, observe the
following precautions.
Identify and analyze the A/C refrigerant of all vehicles prior to refrigerant charging. Failure
to do so can contaminate the shop bulk refrigerant and other vehicles.
Do not add R-12 refrigerant to an A/C system that requires the use of R-134a refrigerant.
These 2 types of refrigerant must never be mixed. Doing so can damage the A/C system.
Charge the A/C system with R-134a refrigerant gas while the engine is running only at the
low-pressure side to prevent refrigerant slugging from damaging the A/C compressor.
Use only R-134a refrigerant. Due to environmental concerns, when the A/C system is
drained, collect the refrigerant using refrigerant recovery/recycling equipment. Federal,
State/Provincial and/or local laws REQUIRE that R-134a be recovered into appropriate
recovery equipment and the process be conducted by qualified technicians who have
been certified by an approved organization, such as ASE or Mobile Air Conditioning
Society (MACS). Use of a recovery machine dedicated to R-134a is necessary to reduce the
possibility of oil and refrigerant incompatibility concerns. Refer to the instructions
provided by the equipment manufacturer when removing refrigerant from or charging the
A/C system.
R-134a Refrigerant must not be mixed with air for leak testing or used with air for any other
purpose above atmospheric pressure. R-134a is combustible when mixed with high
concentrations of air and higher pressures.
A number of manufacturers are producing refrigerant products described as direct
substitutes for R-134a. The use of any unauthorized substitute refrigerant can severely
damage the A/C components. If repair is required, use only new or recycled R-134a
refrigerant.
NOTICE: To avoid contamination of the Air Conditioning (A/C) system, observe the following
precautions.
Never open or loosen a connection before recovering the refrigerant.
When loosening a connection, if any residual pressure is evident, allow it to leak out
before opening the fitting.
Evacuate a system that has been opened to install a new component or one that has
discharged through leakage before charging.
Seal open fittings with a cap or plug immediately after disconnecting a component from
the system.
Clean the outside of the fittings thoroughly before disconnecting a component from the
system.
Do not remove the sealing caps from a new component until ready to install.
Refrigerant oil will absorb moisture from the atmosphere if left uncapped. Do not open an
oil container until ready to use and install the cap immediately after using. Store the oil in
a clean, moisture-free container.
Install a new O-ring seal before connecting an open fitting. Coat the fitting and O-ring seal
with PAG oil before connecting.
When installing a refrigerant line, avoid sharp bends. Position the line away from the
exhaust or any sharp edges that can chafe the line.
Tighten threaded fittings only to specifications. The steel and aluminum fittings used in
the refrigerant system will not tolerate overtightening.
When disconnecting a fitting, use a wrench on both halves of the fitting to prevent twisting
of the refrigerant lines or tubes.
Do not open a refrigerant system or uncap a new component unless it is as close as
possible to room temperature. This will prevent condensation from forming inside a
component that is cooler than the surrounding air.

Principles of Operation
The Refrigerant Cycle
During stabilized conditions (A/C system shutdown), the refrigerant pressures are equal throughout the system.
When the A/C compressor is in operation, it increases pressure on the refrigerant vapor, raising its
temperature. The high-pressure and high-temperature vapor is then released into the top of the A/C condenser
core.
The A/C condenser, being close to ambient temperature, causes the refrigerant vapor to condense into a liquid
when heat is removed from the refrigerant by ambient air passing over the fins and tubing. The now liquid
refrigerant, still at high pressure, exits from the bottom of the A/C condenser and enters the inlet side of the A/C
receiver/drier. The receiver/drier is designed to remove moisture from the refrigerant.
The outlet of the receiver/drier is connected to the Thermostatic Expansion Valve (TXV). The TXV provides the
orifice which is the restriction in the refrigerant system and separates the high and low pressure sides of the
A/C system. As the liquid refrigerant passes across this restriction, its pressure and boiling point are reduced.
The liquid refrigerant is now at its lowest pressure and temperature. As it passes through the A/C evaporator, it
absorbs heat from the airflow passing over the plate/fin sections of the A/C evaporator. This addition of heat
causes the refrigerant to boil (convert to gas). The now cooler air can no longer support the same humidity level
of the warmer air and this excess moisture condenses on the exterior of the evaporator coils and fins and
drains outside the vehicle.
The refrigerant cycle is now repeated with the A/C compressor again increasing the pressure and temperature
of the refrigerant.
The evaporator discharge air temperature sensor monitors the temperature of the evaporator core controls A/C
clutch cycling. If the temperature of the evaporator core is low enough to cause the condensed water vapor to
freeze, the A/C clutch is disengaged by the PCM.
The high-side line pressure is monitored by the A/C pressure transducer so that A/C compressor operation is
interrupted if the system pressure becomes too high or is determined to be too low (low charge condition).
The A/C compressor relief valve opens and vents refrigerant to relieve unusually high system pressure.

Pinpoint Test C: DTC B1B71:11 or B1B71:13
Refer to Wiring Diagrams Cell 54 , Manual Climate Control System for schematic and connector information.
Normal Operation
The evaporator discharge air temperature sensor receives a ground from the Instrument Panel Cluster (IPC).
The sensor varies its resistance with the temperature. As the temperature rises, the resistance falls. As the
temperature falls, the resistance rises. The IPC measures this resistance on the feedback circuit to determine
the temperature at the sensor. The sensor value is sent from the IPC to the PCM through the High Speed
Controller Area Network (HS-CAN).
The evaporator discharge air temperature sensor is used for A/C compressor cycling. An accurate evaporator
discharge air temperature is critical to prevent evaporator icing. The PCM uses the temperature measurement
to turn off the A/C compressor before the evaporator temperature is cold enough to freeze the condensation.
This prevents ice blockage of airflow over the evaporator core.
DTC B1B71:11 (Evaporator Discharge Air Temperature Sensor: Circuit Short to Ground) — The module
senses lower than expected voltage on the sensor feedback circuit, indicating a short to ground.
DTC B1B71:13 (Evaporator Discharge Air Temperature Sensor: Circuit Open) — The module senses
greater than expected voltage on the sensor feedback circuit, indicating an open circuit or sensor.

Pinpoint Test H: Incorrect/Erratic Direction of Airflow From Outlets
Refer to Wiring Diagrams Cell 54 , Manual Climate Control System for schematic and connector information.
Normal Operation
The HVAC module supplies voltage and ground to the defrost/panel/floor mode door actuator motor through the
actuator motor circuits to rotate the defrost/panel/floor mode door actuator. To reverse the defrost/panel/floor
mode door actuator rotation, the HVAC module reverses voltage and ground on the circuits.
The defrost/panel/floor mode door actuator feedback resistor is supplied a 5-volt reference voltage and ground
from the HVAC module. The HVAC module measures the resistance on the defrost/panel/floor mode door
actuator feedback circuit to determine the defrost/panel/floor mode door actuator position by the position of the
actuator feedback resistor wiper arm.
During an actuator calibration cycle, the HVAC module drives the defrost/panel/floor mode door until the door
reaches both internal stops in the HVAC case. If the defrost/panel/floor mode door is temporarily obstructed or
binding during a calibration cycle, the HVAC module may interpret this as the actual end of travel for the door.
When this condition occurs and the HVAC module commands the actuator to its end of travel, the airflow may
not be from the expected outlets.
DTC 3-1 (Mode Feedback Circuit/Performance) — The module senses no changes in the feedback
circuit when motor movement is commanded and no motor electrical DTCs are present. This indicates
an open actuator motor, an open or shorted feedback circuit, an open feedback resistor reference
voltage circuit, or an internal electrical or mechanical failure.
DTC 3-2 (Mode Motor Driver Circuit/Performance) — The module senses lower than expected voltage
on an actuator motor circuit when voltage is applied to drive the motor. This indicates a short to ground
or the module senses greater than expected voltage on the actuator motor circuit when ground is applied
to drive the motor, indicating a short to voltage.
DTC 3-3 (Mode Actuator Calibration Performance) — The module senses the actuator has moved
outside its travel limits during calibration. This indicates broken/disconnected linkage or door or an
internal mechanical failure.

Pinpoint Test J: The Air Conditioning (A/C) is Inoperative
Refer to Wiring Diagrams Cell 54 , Manual Climate Control System for schematic and connector information.
Normal Operation
When A/C is requested the HVAC module grounds a circuit to the Instrument Panel Cluster (IPC). The IPC then
sends an A/C request through the High Speed Controller Area Network (HS-CAN) to the PCM.
Voltage is provided to the A/C clutch relay coil and switch contacts. When A/C is requested and A/C line
pressures allow, a ground is provided to the A/C clutch relay coil from the PCM, energizing the A/C clutch relay.
When the PCM energizes the relay, voltage is supplied to the A/C clutch from the relay. Ground is supplied for
the A/C clutch.
The evaporator discharge air temperature sensor is used for A/C compressor cycling. An accurate evaporator
temperature is critical for compressor engagement. The PCM uses the temperature measurement to turn the
A/C compressor off before the evaporator temperature is cold enough to freeze the condensation on the
evaporator core.
When an A/C request is received by the PCM, the A/C compressor clutch only engages the A/C clutch relay if
all of the following conditions are met:
The A/C pressure transducer does not indicate excessively low or high refrigerant pressure. Refer to
Specifications in this section.
The PCM does not detect excessively high engine coolant temperature.
The PCM does not detect an ambient air temperature below 0°C (32°F).
The PCM has not detected a Wide Open Throttle (WOT) condition.
The HVAC module does not detect an evaporator discharge air temperature below 0.6°C (33°F).
DTC 52 (A/C Select Drive Circuit/Performance) — This DTC sets when any of the following occur during
a self-test:
The module senses ground on the A/C request circuit when the circuit is not grounded by the
HVAC module, indicating a short directly to ground.

Refer to Wiring Diagrams Cell 54 , Manual Climate Control System for schematic and connector information.
Normal Operation
When A/C is requested the HVAC module grounds a circuit to the Instrument Panel Cluster (IPC). The IPC then
sends an A/C request through the High Speed Controller Area Network (HS-CAN) to the PCM.
Voltage is provided to the A/C clutch relay coil and switch contacts. When A/C is requested and A/C line
pressures allow, a ground is provided to the A/C clutch relay coil from the PCM, energizing the A/C clutch relay.
When the PCM energizes the relay, voltage is supplied to the A/C clutch from the relay. Ground is supplied for
the A/C clutch.
The evaporator discharge air temperature sensor is used for A/C compressor cycling. An accurate evaporator
temperature is critical for compressor engagement. The PCM uses the temperature measurement to turn the
A/C compressor off before the evaporator temperature is cold enough to freeze the condensation on the
evaporator core.

Pinpoint Test M: Temperature Control is Inoperative/Does Not Operate Correctly
Refer to Wiring Diagrams Cell 54 , Manual Climate Control System for schematic and connector information.
Normal Operation
The HVAC module supplies voltage and ground to the temperature blend door actuator motor through the
actuator motor circuits to rotate the temperature blend door actuator. To reverse the temperature blend door
actuator rotation, the HVAC module reverses the voltage and ground on the circuits.
The temperature blend door actuator feedback resistor is supplied a 5-volt reference voltage and ground from
the HVAC module. The HVAC module measures the resistance on the temperature blend door actuator
feedback circuit to determine the temperature blend door actuator position by the position of the actuator
feedback resistor wiper arm.
During an actuator calibration cycle, the HVAC module drives the temperature blend door until the door reaches
both internal stops in the HVAC case. If the temperature blend door is temporarily obstructed or binding during
a calibration cycle, the HVAC module may interpret this as the actual end of travel for the door. When this
condition occurs and the HVAC module commands the actuator to its end of travel, the airflow may not be the
expected temperature.
DTC 2-1 (Blend Feedback Circuit/Performance) — The module senses no changes in the feedback
circuit when motor movement is commanded and no motor electrical DTCs are present. This indicates
an open actuator motor, an open or shorted feedback circuit, an open feedback resistor reference
voltage circuit, or an internal electrical or mechanical failure.
DTC 2-2 (Blend Motor Driver Circuit/Performance) — The module senses lower than expected voltage
on an actuator motor circuit when voltage is applied to drive the motor. This indicates a short to ground
or the module senses greater than expected voltage on the actuator motor circuit when ground is applied
to drive the motor, indicating a short to voltage.
DTC 2-3 (Blend Actuator Calibration Performance) — The module senses the actuator has moved
outside its travel limits during calibration. This indicates broken/disconnected linkage or door or an
internal mechanical failure.
This pinpoint test is intended to diagnose the following:
Wiring, terminals or connectors
Temperature blend door actuator
HVAC module
Temperature blend door is binding or stuck

Normal Operation
The blower motor relay coil and relay switch contacts receive voltage. The blower motor relay is energized
when the coil receives ground from the HVAC module, if the HVAC power is on. When the relay coil is
energized, voltage is delivered to the blower motor. Ground for the blower motor is provided from the blower
resistor or the blower switch (HI). The blower resistor is grounded through the blower motor switch. The blower
motor switch is grounded. The blower motor switch is part of the HVAC module and can not be replaced
separately.

Heater Core
1. NOTE: If a heater core leak is suspected, test he heater core by following the plugged heater core
component test before the heater core pressure test. Carry out a system inspection by checking the
heater system thoroughly.
Inspect for evidence of coolant leakage at the heater hose to heater core attachments. A coolant leak in
the heater hose could follow the heater core tube to the heater core and appear as a leak in the heater
core.
2. NOTE: Spring-type clamps are installed as original equipment. Installation and overtightening of nonspecified clamps can cause leakage at the heater hose connection and damage the heater core.
Check the integrity of the heater hose clamps.
Heater Core — Plugged
1. Verify that the engine coolant is at the correct level.
2. Start the engine and turn on the heater.
3. When the engine coolant reaches operating temperature, check the heater core inlet and outlet hoses to
see if they are hot.
4. If the outlet only is not hot the heater core may have an air pocket or may be plugged.
5. If the inlet only is not hot the thermostat may not be working correctly.
Heater Core — Pressure Test
Use the Pressure Test Kit to carry out the pressure test.
1. NOTE: Due to space limitations, a bench test may be necessary for pressure testing.
Drain the coolant from the cooling system.
2. Disconnect the heater hoses from the heater core.
3. Install a short piece of heater hose, approximately 101 mm (4 in) long on each heater core tube.
4. Fill the heater core and heater hoses with water and install the plug BT-7422-B and the adapter BT7422-A from the Pressure Test Kit. Secure the heater hoses, plug and adapter with hose clamps.
5. Attach the pump and gauge assembly from the Pressure Test Kit to the adapter.
6. Close the bleed valve at the base of the gauge. Pump 138 kPa (20 psi) of air pressure into the heater
core.
7. Observe the pressure gauge for a minimum of 3 minutes.
8. If the pressure drops, check the heater hose connections to the heater core tubes for leaks. If the heater
hoses do not leak, remove the heater core from the vehicle and carry out the bench test.
Heater Core — Bench Test
1. Remove the heater core from the vehicle.
2. Drain all of the coolant from the heater core.
3. Connect the 101 mm (4 in) test heater hoses with plug and adapter to the heater core tubes. Then
connect the Pressure Test Kit to the adapter.
4. Apply 138 kPa (20 psi) of air pressure to the heater core. Submerge the heater core in water.
5. If a leak is observed, install a new heater core.
Evaporator/Condenser Core — On-Vehicle Leak Test
1. Discharge and recover the refrigerant. Refer to Air Conditioning (A/C) System Recovery, Evacuation and
Charging in this section.
2. Disconnect the suspect evaporator core or condenser core from the A/C system.
3. Clean the manifold fittings.
4. Connect the appropriate test fittings from the A/C Flush Adapter Kit to the condenser or evaporator core
tube connections.
5. NOTE: The automatic shut-off valves on some gauge set hoses do not open when connected to the test
fittings. If available, use hoses without shut-off valves. If hoses with shut-off valves are used, make sure
the valve opens when attached to the test fittings or install an adapter that will activate the valve. The
test is not valid if the shut-off valve does not open.
Attach the correct adapters from the Adapters/O-rings for Filter kit to the test fittings and connect the red
and blue hoses from the R-134a Manifold Gauge Set to the test fittings on the evaporator core or
condenser core. Connect the yellow hose to a known good vacuum pump.
6. Open both gauge set valves and start the vacuum pump. Allow the vacuum pump to operate for a
minimum of 45 minutes after the gauge set low pressure gauge indicates 101 kPa (30 in-Hg). The 45
minute evacuation is necessary to remove any refrigerant from oil left in the evaporator core or
condenser core. If the refrigerant is not completely removed from the oil, outgassing degrades the
vacuum and appears as a refrigerant leak.
7. If the low pressure gauge reading will not drop to 101 kPa (30 in-Hg) when the valves on the gauge and
manifold set are open and the vacuum pump is operating, close the gauge set valves and observe the
low pressure gauge. If the pressure rises rapidly to zero, a large leak is indicated. Recheck the test fitting
connections and gauge set connections before installing a new evaporator core or condenser core.
8. After evacuating for 45 minutes, close the gauge set valves and stop the vacuum pump. Observe the low
pressure gauge; it should remain at the 101 kPa (30 in-Hg) mark.
If the low pressure gauge reading rises 34 kPa (10 in-Hg) or more of vacuum from the 101 kPa
(30 in-Hg) position in 10 minutes, a leak is indicated.
If a very small leak is suspected, wait 30 minutes and observe the vacuum gauge.
If a small amount of vacuum is lost, operate the vacuum pump with gauge valves open for an
additional 30 minutes to remove any remaining refrigerant from the oil in the evaporator core or
condenser core. Then recheck for loss of vacuum.
If a very small leak is suspected, allow the system to sit overnight with vacuum applied and check
for vacuum loss.
9. If the evaporator core or condenser core leaks, as verified by the above procedure, install a new
evaporator core or condenser core.
A/C Compressor — External Leak Test
1. Install the adapter from the A/C Flush Adapter Kit on the port of the A/C compressor, using the existing
manifold retaining bolt.
2. Connect the high and low pressure lines of a manifold gauge set or a refrigerant recovery/recycling
station to the corresponding fittings on the adapter.
3. Attach the center hose of a manifold gauge set to a refrigerant container standing in an upright position.
4. Open the low pressure gauge valve, the high pressure gauge valve and the valve on the refrigerant
container to allow the refrigerant vapor to flow into the A/C compressor.
5. Using the Refrigerant Leak Detector, check for leaks at the compressor shaft.
6. If an external leak is found, install a new A/C compressor.
7. When the leak test is complete, recover the refrigerant from the compressor.

WARNING: Carry out this procedure in a well-ventilated area with all vehicle windows and
doors opened. Carefully read cautionary information on product label. For EMERGENCY
MEDICAL INFORMATION, seek medical advice. On Ford/Motorcraft products in the USA or
Canada call: 1-800-959-3673. For additional information, consult the product Material Safety Data
Sheet (MSDS), if available. Failure to follow these instructions may result in serious personal
injury.
NOTE: There are typically 4 types of objectionable odors found in a vehicle:
Chemical odors
Environmental odors
Human and other interior-generated odors
Microbiological odors
Before determining that A/C odor treatment is required, the source and the circumstances under which
the odor occurs must be determined.
NOTE: Chemical odors are usually constant regardless of the climate control system setting although
they may be enhanced by A/C operation. Most chemical odors are caused by fluid leaks or incorrectly
cured adhesives. Chemical odors can be eliminated by repairing the leaking component and removing
any residue.
NOTE: Environmental odors usually occur for a short time and diminish after the vehicle passes through
the affected area. These odors are typically only detected when the vehicle windows are open, or when
the climate control system is operating in a mode that allows for fresh air. Environmental odors cannot
be eliminated because they are external in source, but they may be minimized by switching to a climate
control setting that uses recirculated air.
NOTE: Human and other interior-generated odors occur while the source is present and may linger for a
short time after. These odors may be more noticeable during A/C operation. Human odors may be
eliminated by removing the source and cleaning the affected area.
NOTE: Microbiological odors, if in the A/C system, usually last for about 30 seconds after the system is
turned on. They will be detected while the A/C is turned on and using either outside or recirculated air.
Microbiological odors that occur in areas other than the A/C system (for example, water in doors or wet
carpeting) may last indefinitely and will be more intense when recirculated air is used. Microbiological
odors will not be present at temperatures at or below 10°C (50°F).
Microbiological odors can be eliminated by removing the source and treating the affected area. Standing
water must be allowed to drain and dry out. A/C systems may be treated by using A/C cooling coil
coating as described in the service procedure below.
Microbiological odors result from microbial growth supported by warm temperatures and moisture.
Microbiological odors are described as musty/mildew type smells and may occur on/in:
foam seals.
rubber seals.
adhesives.
standing water.
water soaked carpet/trim.
1. Identify the type of odor present in the vehicle. Do not proceed with A/C odor treatment if the odor
source is found to be outside of the A/C system. Refer to the following chart for examples.

2. Identify the source of the odor.
Check the evaporator core drain tube for restriction.
Check the passenger and driver side carpet for moisture. If moisture is found, A/C odor
treatment is not necessary. Diagnose for a water leak as needed.
Check the blower motor and blower motor cover (if equipped) for moisture resulting from
water bypassing the cowl baffling system. If moisture is found, A/C odor treatment is not
necessary. Diagnose for a water leak as needed.
Check the cowl top panel and air inlet screen for standing water or foreign material. If
possible, remove any standing water and clean the air inlet screen using a wet/dry
vacuum.
3. Open all vehicle windows and doors.
4. Make sure that the A/C is off.
5. Set the following.
Select PANEL mode (A/C off).
Adjust the temperature setting to full warm.
Adjust the blower motor speed to HI.
6. Run the engine for 25 minutes to dry out the A/C system.
7. Turn the ignition OFF.
8. Remove the blower motor.
9. NOTE: Blower motor speed controls that are mounted outside of the evaporator core housing and
not exposed to the blower motor airflow do not need to be removed.
Remove the blower motor resistor (if equipped) or blower motor speed control (if equipped and
exposed to the inside of the evaporator core housing).
10. NOTICE: To avoid damage to the vehicle interior, do not spill or spray this product on any
interior surface.
Add one full bottle of A/C cooling coil coating to the Flexible Applicator Tool.
11. Insert the nozzle into the evaporator housing and direct the spray toward the evaporator core
face. Spray the entire evaporator core face until empty.

Heated Pentode Halogen Leak
Detector
023-00178 or equivalent
NOTE: Good ventilation is necessary in the area where electronic A/C leak testing is to be carried out. If
the surrounding air is contaminated with refrigerant gas, the Heated Pentode Halogen Leak Detector will
indicate this gas all the time. Odors from other chemicals such as antifreeze, diesel fuel, disc brake
cleaner or other cleaning solvents can cause the same problem. Using a fan to ventilate the area to be
tested before proceeding with the leak detection procedure is helpful in removing small traces of
contamination from the air, but the fan should be turned off during actual testing.
NOTE: R-134a is heavier than air, and will tend to move downward from the source of the leak if
present. It is possible that a leak may not be detected if the leak detector tip is held above the leaking
fitting, line or component. Always be sure to thoroughly leak test below the fitting, line or component for
the presence of R-134a as well as leak testing above and around.
1. NOTE: The system pressure should be between 413-551 kPa (60-80 psi) at 24°C (75°F) with the
engine off and cool. The pressure reading may be higher if the engine is hot.
Leak test the refrigerant system using the Heated Pentode Halogen Leak Detector. Follow the
instructions included with the Heated Pentode Halogen Leak Detector for handling and operation
techniques.

Fluorescent Dye Injection Using a R-134a Refrigerant Management Machine and Dye Injector —
Vehicles Requiring R-134a Addition
NOTE: This method of fluorescent dye injection requires the addition of R-134a from a R-134a
Refrigerant Management Machine or R-134a Manifold Gauge Set hooked to an external tank to charge
the dye into the refrigerant system. If adding fluorescent dye to a refrigerant system that is already fully
charged, the R-134a Loop/Add On Injector Kit-Set method should be used.
NOTE: Fluorescent refrigerant system dye is added to the refrigerant system at the factory to assist in
refrigerant system leak diagnosis using a Rotunda-approved UV blacklight. It is not necessary to add
additional dye to the refrigerant system before diagnosing leaks, even if a significant amount of
refrigerant has been removed from the system. Replacement suction accumulators and receiver/driers
are shipped with a fluorescent dye "wafer" included in the desiccant bag which will dissolve after
approximately 30 minutes of continued A/C operation. It is not necessary to add dye after flushing or
filtering the refrigerant system because a new suction accumulator or receiver/drier is installed as part of
the flushing or filtering procedure. Additional refrigerant system dye should only be added if more than
50% of the refrigerant system lubricant capacity has been lost due to a fitting separation, hose rupture or
other damage.
NOTE: Before using the R-134a Loop/Add On Injector Kit-Set for the first time, refer to the
manufacturer's instructions on evacuation of any non-condensable gases from the hoses.
NOTE: Only connect the dye/lubricant injector from the R-134a Loop/Add On Injector Kit-Set when
fluorescent dye is to be injected. The dye/lubricant injector has a one-way check valve that will prevent
refrigerant system recovery and evacuation.
1. NOTE: If no R-134a pressure is present in the refrigerant system, the system should be
evacuated before carrying out the injection procedure. For additional information, refer to Air
Conditioning (A/C) System Recovery, Evacuation and Charging in this section.
Connect a R-134a Refrigerant Management Machine or a R-134a Manifold Gauge Set to the
refrigerant system service port valves.
2. Verify that the valves on the dye/lubricant injector from the R-134a Loop/Add On Injector Kit-Set
are closed.
3. Fill the R-134a fluorescent dye injector reservoir with 7 ml (0.25 oz) of fluorescent dye.
4. Install the dye/lubricant injector between the low-pressure service gauge port valve and the R134a Refrigerant Management Machine or R-134a Manifold Gauge Set.
5. NOTE: Following fluorescent dye injection, the refrigerant system should be fully charged to make
sure of correct movement of the dye.
Open all valves and inject the fluorescent dye into the refrigerant system by charging the
refrigerant system with the required amount of R-134a.
6. When fluorescent dye injection is complete, close all valves.
7. Recover the refrigerant from the dye/lubricant injector.
8. Remove the dye/lubricant injector from the low-pressure service gauge port valve and the R-134a
Refrigerant Management Machine or R-134a Manifold Gauge Set.
Fluorescent Dye Injection Using a R-134a Loop/Add On Injector Kit-Set — Vehicles Not Requiring

50% of the refrigerant system lubricant capacity has been lost due to a fitting separation, hose rupture or
other damage.
NOTE: Before using the R-134a Loop/Add On Injector Kit-Set for the first time, refer to the equipment
manufacturer's instructions on evacuation of non-condensable gases from the hoses.
NOTE: Refrigerant system pressure should be between 413-551 kPa (60-80 psi) at 24°C (75°F) with the
engine off and cool.
1. Verify that the valves on the R-134a Loop/Add On Injector Kit-Set are closed.
2. Fill the R-134a Loop/Add On Injector Kit-Set reservoir with 7 ml (0.25 oz) of fluorescent dye.
3. Install the R-134a Loop/Add On Injector Kit-Set between the high-pressure and low-pressure
service gauge port valves.
4. NOTICE: Make sure all tools and hoses are clear of the engine cooling fan and drive belt
before starting the engine. Failure to keep tools and hoses clear from the engine cooling
fan and drive belt will result in damage to the tools and/or vehicle.
With the A/C off, start the engine. Allow engine speed to stabilize below 1,000 rpm.
5. Set the A/C to the ON position.
6. Open the high-pressure service valve.
7. NOTE: To prevent pressure spike/liquid slug, crack the R-134a Loop/Add On Injector Kit-Set
valves and slowly open to inject the fluorescent dye into the refrigerant system.
Open the R-134a Loop/Add On Injector Kit-Set valves and inject the fluorescent dye into the
refrigerant system.
8. Close the high-pressure service valve to allow the pressure inside the R-134a Loop/Add On
Injector Kit-Set to equalize with the suction side of the refrigerant system.
9. NOTE: Close the valves on the R-134a Loop/Add On Injector Kit-Set while the A/C compressor is
operating.
Close the valves on the R-134a Loop/Add On Injector Kit-Set.
10. NOTE: Leave all valves on the R-134a Loop/Add On Injector Kit-Set closed when not in use.
Disconnect the high-pressure and low-pressure service valves and remove the R-134a Loop/Add
On Injector Kit-Set from the vehicle.
Fluorescent Dye Detection
NOTE: Ford Motor Company vehicles are produced with R-134a fluorescent dye installed in the
refrigerant system from the factory. The location of leaks can be pinpointed by the bright yellow-green
glow of the fluorescent dye under a UV lamp. Since more than one leak can exist, make sure to inspect
each component, line and fitting in the refrigerant system for a leak.
NOTE: Use of dye-enhancing glasses or goggles greatly improves the detection of the dye under the UV
lamp.
NOTE: Not all UV lamps will fluoresce the dye used in Ford vehicles. All Rotunda UV lamps are
optimized to fluoresce the dye.
1. Check for leaks using a Rotunda-approved UV lamp and dye enhancing glasses.
Inspect all components, lines and fittings of the refrigerant system.
2. After the leak(s) is repaired, remove any traces of fluorescent dye with a general purpose oil
solvent.
3. Verify the repair by running the vehicle for a short period of time and rechecking the area of the
leak with a Rotunda-approved UV lamp.

WARNING: Use extreme care and observe all safety and service precautions related to the
use of refrigerants as outlined on refrigerant tank and on recovery and charging equipment.
Failure to follow these instructions may result in serious personal injury.
WARNING: Carefully read cautionary information on product label. For EMERGENCY
MEDICAL INFORMATION seek medical advice. In the USA or Canada on Ford/Motorcraft
products call: 1-800-959-3673. For additional information, consult the product Material Safety
Data Sheet (MSDS) if available. Failure to follow these instructions may result in serious personal
injury.
NOTICE: An Air Conditioning (A/C) refrigerant analyzer must be used before the recovery of any
vehicle A/C refrigerant. Failure to do so puts the shop bulk refrigerant at risk of contamination. If
the vehicle A/C refrigerant is contaminated, refer the customer to the repair facility that carried
out the last A/C repair. All contaminated A/C refrigerant must be disposed of as hazardous
waste. For all equipment, follow the equipment manufacturer procedures and instructions.
NOTICE: The Thermostatic Expansion Valve (TXV) and hoses with mufflers, should be removed
when flushing the Air Conditioning (A/C) system. Internal plumbing of these devices makes it
impossible to correctly remove any residual-flushing agent. These components are typically
discarded after A/C system contamination. Hoses without mufflers can normally be reused
unless they are clogged with foreign material.
NOTE: Prior to using the A/C Flush and Purge Machine 219-00022 for the first time, review the
operating instructions.
NOTE: Only the A/C Flush and Purge Machine kit, which includes A/C Flush and Purge Machine, A/C
Flush and Purge Fitting Kit and the A/C Systems Flushing Solvent, is approved for use. No other
flushing device or solvent is approved for flushing heat exchangers (A/C condenser, A/C evaporator).
Use of any other flusher or solvent may cause damage to the A/C system and the flushing unit.
NOTE: Ford Motor Company has approved a procedure to provide technicians with a nonChlorofluorocarbons (CFC) method of flushing contaminated A/C system heat exchangers. The
procedure allows the specific components to be cleaned and flushed while installed in their normal invehicle location. The types of contamination flushed include particle matter that results from A/C
compressor or desiccant failure and gummy residue that can form when refrigerant oil is overheated
during A/C compressor seizure. The flushing process is a 2-step procedure that involves the use of an
A/C Flush and Purge Machine to:
circulate the flushing solvent through the heat exchanger in the reverse direction of normal
refrigerant flow (back-flushing). Particulate matter picked up during flushing is filtered from the
returning solvent before the solvent is returned to the reservoir for continued circulation.
remove the flushing solvent from the heat exchanger. In this step of the procedure, pressurized
air 621-862 kPa (90-125 psi) is used to push and evaporate any remaining flush solvent from the
heat exchanger.
1. Recover the refrigerant. For additional information, refer to Air Conditioning (A/C) System
Recovery, Evacuation and Charging in this section.
2. Disconnect the refrigerant lines from the heat exchanger(s) to be flushed.
3. Connect the A/C Flush and Purge Machine to the heat exchanger to be flushed using the
Refrigerant Flushing Equipment Connector or the correct adapters from the A/C Flush Adapter
Kit. Do not flush through the evaporator core orifice or hoses. The internal plumbing and material
make-up of these components make it impossible to correctly remove foreign material or residual
flushing solvent.
4. NOTE: Flush the heat exchanger for a minimum of 15 minutes. The flush solvent may be used for
one or both heat exchangers in the A/C system. However, the flush solvent and the flushing unit
filter is intended for one vehicle only.
Flush the heat exchanger for a minimum of 15 minutes.
5. Apply 621-862 kPa (90-125 psi) of pressurized air to the component for a minimum of 30 minutes.
The 30-minute purge time is required to force and evaporate all residual solvent from the A/C
system component. Failure to successfully remove all residual solvent within the component can
result in system damage when reconnected and operated. Dispose of the used flush solvent and
filter in accordance with local, state and federal regulations.
6. NOTE: A/C system filtering as described in this section is optional if system flushing is carried
out. However, the filter kit use is recommended after flushing if the A/C system contamination is
extensive.
Install a new Thermostatic Expansion Valve (TXV) in any vehicle being repaired for an internal
A/C compressor or desiccant failure.
7. Install new refrigerant hoses if clogged with foreign material.
8. Install a new receiver/drier in any vehicle being repaired for an internal A/C compressor or
desiccant failure.
9. Reconnect the heat exchanger being repaired.
10. If a new A/C compressor is not to be installed, lubricate the refrigerant system with the correct
amount of clean PAG oil. For additional information, refer to Refrigerant Oil Adding in this section.
11. If a new A/C compressor is not to be installed, evacuate, leak test, and charge the A/C system.
For additional information, refer to Air Conditioning (A/C) System Recovery, Evacuation and
Charging in this section.

Refrigerant System Recovery
NOTICE: An Air Conditioning (A/C) refrigerant analyzer must be used before the recovery of any
vehicle's A/C refrigerant. Failure to do so puts the shop's bulk refrigerant at risk of
contamination. If the vehicle's A/C refrigerant is contaminated, refer the customer to the service
facility that carried out the last A/C service. If the customer wishes to pay the additional cost, use
the A/C recovery equipment that is designated for recovering contaminated A/C refrigerant. All
contaminated A/C refrigerant must be disposed of as hazardous waste. For all equipment, follow
the equipment manufacturer procedures and instructions.
NOTE: Ford Motor Company recommends the use of R-134a refrigerant management equipment that
meets the requirements of the SAE J2788 standard.
1. Prior to recovering, the purity of the refrigerant must be verified. For additional information, refer
to Refrigerant Identification Testing in this section.
2. Connect a R-134a Refrigerant Management Machine to the low- and high-pressure service gauge
port valves following the operating instructions provided by the equipment manufacturer.
3. Recover the refrigerant from the system following the operating instructions provided by the
equipment manufacturer. Note the amount of oil removed during the refrigerant recovery (if any).
Add that same amount back into the system once repairs are complete.
4. Once the R-134a Refrigerant Management Machine has recovered the refrigerant, switch OFF
the power supply.
5. Allow the system to set for about 2 minutes, and observe the system vacuum reading. If the
vacuum is not lost, disconnect the recovery equipment.
6. If the system does lose vacuum, repeat Steps 3 through 5 until the vacuum level remains stable
for 2 minutes.
7. Carry out the required repairs.
Refrigerant System Evacuation Using a R-134a Refrigerant Management Machine
1. Connect a R-134a Refrigerant Management Machine to the low- and high-pressure service gauge
port valves following the operating instructions provided by the equipment manufacturer.
2. Evacuate the system until the low-pressure gauge reads at least 99.4 kPa (29.5 in-Hg) of vacuum
and as close to 101.1 kPa (30 in-Hg) as possible. Continue to operate the Vacuum Pump for a
minimum of 45 minutes.
3. Turn OFF the Vacuum Pump. Observe the low-pressure gauge for 5 minutes to make sure that
the system vacuum is held.
Refrigerant System Evacuation Using a R-134a Manifold Gauge Set and Vacuum Pump
NOTE: Leaks in refrigerant system service equipment, hoses or gauges can cause a leak in vacuum
that may be misinterpreted as a problem with the vehicle's refrigerant system. It is necessary to leak-test
all refrigerant system service equipment, hoses and gauges on a weekly basis to verify that no leaks are
present.
1. Connect the R-134a Manifold Gauge Set to the low-side and high-side service gauge port valves.
2. Connect the center (yellow) hose from the R-134a Manifold Gauge Set to the suction port on the
Vacuum Pump.
3. Open all valves on the R-134a Manifold Gauge Set and both service gauge port valves.
4. Turn on the Vacuum Pump and evacuate the system until the low-pressure gauge reads at least
99.4 kPa (29.5 in-Hg) of vacuum and as close to 101.1 kPa (30 in-Hg) as possible. Continue to
operate the Vacuum Pump for a minimum of 45 minutes.
5. Close the high-side and low-side valves on the R-134a Manifold Gauge Set (not the service
gauge port valves) and turn OFF the Vacuum Pump.
6. Observe the low-pressure gauge for 5 minutes to make sure that the system vacuum is held. If
vacuum is not held for 5 minutes, leak test the system, repair the leak and evacuate the system
again.

NOTICE: An Air Conditioning (A/C) refrigerant analyzer must be used before the recovery of any
vehicle's A/C refrigerant. Failure to do so puts the shop's bulk refrigerant at risk of
contamination. If the vehicle's A/C refrigerant is contaminated, refer the customer to the service
facility that carried out the last A/C service. If the customer wishes to pay the additional cost, use
the A/C recovery equipment that is designated for recovering contaminated A/C refrigerant. All
contaminated A/C refrigerant must be disposed of as hazardous waste. For all equipment, follow
the equipment manufacturer's procedures and instructions.
NOTICE: On vehicles being serviced for an internal compressor or desiccant failure, a new
suction accumulator or receiver/drier, Thermostatic Expansion Valve (TXV) or evaporator core
orifice and any hoses containing mufflers must be installed prior to filtering the Air Conditioning
(A/C) system. Internal plumbing of these devices makes it impossible to correctly remove any
foreign material. These components are typically discarded after A/C system contamination.
Hoses without mufflers can normally be reused unless they are clogged with foreign material.
The filter is intended for use on one vehicle only.
1. NOTE: The filter inlet is marked with a label on one side of the filter body.
Orient the filter inlet toward the A/C condenser core.
2. NOTICE: The flexible extension adapters included in the A/C Flush Adapter Kit are
designed for low-pressure flushing and are not designed for use with a charged refrigerant
system. Do not make the condenser fitting connections using the flexible extension
adapters or damage to the adapters and loss of refrigerant will occur.
NOTE: The F8VZ-19E773-AB pancake filter is not permanently installed and will be removed at
the end of this procedure.
Disconnect the condenser outlet fitting and temporarily install the pancake filter between the 2
halves of the fitting.
Use flexible R-134a service hoses of 17,238 kPa (2,500 psi) burst rating.
Make the connections using the correct adapters from the A/C Flush Adapter Kit and/or
A/C Flush and Purge Fitting Kit.
3. Lubricate the refrigerant system with the correct amount of clean PAG oil. For additional
information, refer to Refrigerant Oil Adding in this section.
4. Evacuate and charge the refrigerant system. For additional information, refer to Air Conditioning
(A/C) System Recovery, Evacuation and Charging in this section.
5. Check all refrigerant system hoses, lines and the position of the newly installed filters to be sure
they do not interfere with other engine compartment components. If necessary, use tie straps to
make adjustments.
6. Provide adequate airflow to the front of the vehicle (with a fan, if necessary). Select A/C operation
and set the blower motor speed to maximum. Start the engine and let it idle briefly. Make sure the
A/C system is operating correctly.

Refrigerant Identification
1. NOTE: A Refrigerant Blend Identifier with Printer must be used to identify gas samples taken
directly from the refrigeration system or storage containers prior to recovering or charging the
refrigerant system.
Follow the instructions included with the Refrigerant Blend Identifier with Printer to obtain the
sample for testing.
2. The Refrigerant Blend Identifier with Printer will display one of the following:
If the purity level of R-134a is 98% or greater by weight, the green PASS LED will light.
The weight concentrations of R-134a, R-12, R-22, hydrocarbons and air will be displayed
on the digital display.
If refrigerant R-134a does not meet the 98% purity level, the red FAIL LED will light and an
alarm will sound alerting the user of potential hazards. The weight concentrations of R134a, R-12, R-22 and hydrocarbons will be displayed on the digital display.
If hydrocarbon concentrations are 2% or greater by weight, the red FAIL LED will light,
"Hydrocarbon High" will be displayed on the digital display, and an alarm will sound alerting
the user of potential hazards. The weight concentrations of R-134a, R-12, R-22 and
hydrocarbons will also be displayed on the digital display.
3. The percentage of air contained in the sample will be displayed if the R-134a content is 98% or
greater. The Refrigerant Blend Identifier with Printer eliminates the effect of air when determining
the refrigerant sample content because air is not considered a contaminant, although air can
affect A/C system performance. When the Refrigerant Blend Identifier with Printer has determined
that a refrigerant source is pure (R-134a is 98% or greater by weight) and air concentration levels
are 2% or greater by weight, it will prompt the user if an air purge is desired.
4. If contaminated refrigerant is detected, repeat the refrigerant identification test to verify that the
refrigerant is indeed contaminated.
Contaminated Refrigerant Handling
NOTICE: If contaminated refrigerant is detected, DO NOT recover the refrigerant into R-134a
recovery/recycling equipment. Recovery of contaminated refrigerant will contaminate the
recovered refrigerant supply and may damage the recovery/recycling equipment.
NOTE: A new suction accumulator or receiver/drier must be installed as directed by the A/C system
flushing procedure.
1. Recover the contaminated refrigerant using suitable recovery-only equipment designed for
capturing and storing contaminated refrigerant only.
If this equipment is not available, contact an A/C service facility in the area with the correct
equipment to carry out this service.
2. Determine and correct the cause of the customer's initial concern.
3. Flush the A/C system.
4. Dispose of the contaminated refrigerant in accordance with all federal, state and local regulations.

SECTION 412-01: Climate Control
DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Air Conditioning
The refrigerant system components include the following:
A/C compressor and clutch assembly
A/C condenser core
A/C evaporator core
Receiver/drier
Connecting refrigerant lines
Thermostatic Expansion Valve (TXV)
The A/C compressor contains a pressure relief valve to protect the refrigerant system against
excessively high refrigerant pressures.
A/C Compressor and Clutch Assembly
NOTE: Internal A/C compressor components are not serviced separately. The A/C compressor is
serviced as an assembly. A new A/C pressure relief valve is included with replacement A/C
compressors, but the valve is also available as a separate component and can be independently
replaced if needed. The A/C compressor clutch, A/C compressor pulley and A/C clutch field coil can be
serviced separately.
The A/C compressor has the following characteristics:
A non-serviceable shaft seal.
Uses PAG Refrigerant Compressor Oil (R-134a Systems) YN-12-D. This oil contains special
additives required for the A/C compressor.
The A/C compressor oil may darken over time while maintaining normal oil viscosity. This is
normal because of break-in wear.
Use the refrigerant oil adding procedure specified for this vehicle when installing a new A/C
compressor or any other A/C component. Refer to the Refrigerant Oil Adding procedure in
Section 412-00 .
When battery voltage is applied to the A/C compressor clutch field coil, the clutch disc and hub assembly
is drawn toward the A/C compressor pulley. The magnetic force locks the clutch disc and hub assembly
and the A/C compressor pulley together as one unit, causing the compressor shaft to rotate with the
engine. When battery voltage is removed from the A/C compressor clutch field coil, springs in the clutch
disc and hub assembly move the clutch disc away from the A/C compressor pulley.
A/C Pressure Relief Valve
NOTE: If the A/C compressor is operating within limits and the A/C pressure relief valve is venting or
leaking around the threads, install a new A/C pressure relief valve and O-ring. If the new A/C pressure
relief valve still vents after it is installed, diagnose the refrigerant system for a restriction.
An A/C pressure relief valve is incorporated in the A/C compressor to prevent damage to the A/C
compressor and other system components by relieving unusually high system discharge pressure
buildups. For specifications regarding operating pressure(s), refer to Section 412-00 .
The A/C pressure relief valve can be serviced separately from the A/C compressor. It is necessary to
recover the refrigerant before removing the A/C pressure relief valve.
A/C Condenser Core
The condenser core is an aluminum fin-and-tube design heat exchanger located in front of the vehicle
radiator. It cools compressed refrigerant gas by allowing air to pass over fins and tubes to extract heat,
and condenses gas to liquid refrigerant as it is cooled.
A/C Evaporator Core
The evaporator core is an aluminum plate/fin type and is located in the heater core and evaporator core
housing. A mixture of liquid refrigerant and oil enters the bottom of the evaporator core through the
evaporator core inlet tube and continues out of the evaporator core through the evaporator core outlet
tube as a vapor. During A/C compressor operation, air flow from the blower motor is cooled and
dehumidified as it flows through the evaporator core fins.
Thermostatic Expansion Valve (TXV)
The Thermostatic Expansion Valve (TXV) is located at the evaporator core inlet and outlet tubes at the
center rear of the engine compartment. The TXV provides a restriction to the flow of refrigerant from the
high-pressure side of the refrigerant system and separates the low-pressure and high-pressure sides of
the refrigerant system. Refrigerant entering and exiting the evaporator core passes through the TXV
through 2 separate flow paths. An internal temperature sensing bulb senses the temperature of the
refrigerant flowing out of the evaporator core and adjusts an internal pin-type valve to meter the
refrigerant flow into the evaporator core. The internal pin-type valve decreases the amount of refrigerant
entering the evaporator core at lower temperatures and increases the amount of refrigerant entering the
evaporator core at higher temperatures.
Receiver/Drier
NOTE: Installation of a new receiver/drier is not required when repairing the A/C system, unless there is
physical evidence of contamination from a failed A/C compressor or damage to the receiver/drier.
Damage to the receiver/drier includes leaks, physical damage to the receiver/drier shell or desiccant, or
moisture contamination. Moisture contamination results only from a complete loss of refrigerant, and
equalization of the refrigerant system pressure with atmospheric pressure for a period longer than one
hour. If even a slight amount of positive refrigerant pressure is present in the refrigerant system before
repairs are carried out, a new receiver/drier should not be installed.
The receiver/drier is mounted to the RH side of the condenser core above the condenser outlet fitting. It
stores high-pressure liquid after it leaves the condenser core. A desiccant cartridge mounted inside the
receiver/drier removes moisture from the refrigerant.
Evaporator Discharge Air Temperature Sensor
The evaporator discharge air temperature sensor contains a thermistor. The resistance of this thermistor
varies by a specific amount based on the evaporator discharge air temperature. The PCM measures a
voltage ratio between the reference voltage it supplies to the sensor and the sensor voltage to determine
this resistance and the associated evaporator discharge air temperature.
As the evaporator core removes heat and moisture from the air flow moving through the evaporator core
fins, the removed moisture condensates on the exterior of the evaporator core. The PCM uses input
from the evaporator discharge air temperature sensor to prevent this moisture from freezing on the
exterior of the evaporator core, and inhibiting air flow through the evaporator core fins. When the
evaporator core temperature drops to a temperature near the freezing point of water, the PCM switches
off the A/C compressor. The A/C compressor is switched back on when the evaporator core temperature
rises to an acceptable level.
The evaporator discharge air temperature sensor is located below the glove compartment outside of the
heater core and evaporator core housing.
A/C Pressure Transducer
The A/C pressure transducer monitors the compressor discharge pressure and communicates with the
PCM. The PCM interrupts A/C compressor operation in the event the A/C pressure transducer indicates
high system discharge pressures. It also to senses low charge conditions. If the pressure is below a
predetermined value for a given ambient temperature, the PCM will not allow the clutch to engage.
The A/C pressure transducer is located at the lower RH corner of the condenser core near the
condenser outlet fitting. It is not necessary to recover the refrigerant before removing the A/C pressure
transducer.
Service Gauge Port Valves
The high-pressure service gauge port valve is located on the compressor-to-condenser discharge line
near the condenser inlet fitting.
The low-pressure service gauge port valve is located on the A/C compressor suction line near the RH
shock tower.

A/C charging valve cap
The service gauge port valve is an integral part of the refrigerant system line or component.
Special couplings are required for both the high-side and low-side service gauge ports.
A very small amount of leakage is always detectable around the Schrader-type valve with the
service gauge port valve cap removed, and is considered normal. If the seal leaks excessively,
install a new Schrader-type valve core.
The service gauge port valve caps each include an O-ring seal used as a primary seal in the
refrigerant system to prevent any leakage through the Schrader-type valves from reaching the
atmosphere. Check the service gauge port valve cap O-ring seals when checking the refrigerant
system for leaks and install a new cap if necessary. Always install and tighten the A/C service
gauge port valve caps to the correct torque after they are removed.
Refrigerant System Dye
Fluorescent refrigerant system dye is added to the refrigerant system at the factory to assist in
refrigerant system leak diagnosis when using a Rotunda-approved ultraviolet black light. It is not
necessary to add additional dye to the refrigerant system before diagnosing leaks, even if a significant
amount of refrigerant has been removed from the system. Replacement receiver/driers are shipped with
a fluorescent dye "wafer" included in the desiccant bag, which dissolves after approximately 30 minutes
of continued A/C operation. It is not necessary to add dye after flushing or filtering the refrigerant system
because a new receiver/drier is installed as part of the flushing or filtering procedure. Only add additional
refrigerant system dye if more than 50% of the refrigerant system lubricant capacity has been lost due to
a fitting separation or hose rupture. Refer to Section 412-00 .

Air Distribution and Filtering
NOTE: The air distribution system is equipped with a factory installed cabin air filter.
There are 2 sources of air available to the air distribution system:
Fresh (outside) air
Recirculated air
Recirculated air is always used when the HVAC module is set to the MAX A/C mode and can be
selected in any mode except DEFROST or FLOOR/DEFROST.
Air distribution within the vehicle is determined by the air flow mode selected. Electric mode door
actuator-positioned airflow mode control doors direct airflow within the heater core and evaporator core
housing.
Air enters the passenger compartment from the following outlets:
Instrument panel registers
Floor duct outlets
Windshield defroster
Side window demisters
Rear footwell duct
Passenger compartment air is exhausted from the vehicle through open windows or body air vents.
Cabin Air Filter
The cabin air filter is located in the heater core and evaporator core housing. For cabin air filter
maintenance intervals, refer to Section 100-03 .
SECTION 412-01: Climate Control
DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 10/22/2010
Control Components
Electronic Manual Temperature Control (EMTC)
The HVAC module allows the vehicle occupants to select the following:
Air inlet source (outside or recirculated)
Blower motor speed
Discharge air temperature (temperature blend)
Discharge air location (defrost, panel, floor, panel/floor, defrost/floor)
A/C compressor operation
Rear window defroster operation
Control System Inputs
The blower motor speed switch is mounted in the HVAC module and controls blower motor speed by
adding or bypassing resistors in the blower motor resistor in all modes except OFF. The blower motor
speed switch is serviced only as an assembly with the HVAC module.
The temperature control switch adjusts the discharge air temperature. Movement of the temperature
knob from COOL (blue) to WARM (red) causes a corresponding movement of the temperature blend
door. The position of the temperature blend door determines the discharge air temperature that the air
distribution system will maintain. The temperature control selector is an integral part of the HVAC
module and cannot be serviced separately.
The airflow mode setting adjusts the discharge air outlet location. Movement of the airflow mode selector
causes a corresponding movement of the airflow mode doors and determines the discharge air outlet
location. The airflow mode selector is an integral part of the HVAC module and cannot be serviced
separately.
The A/C request button determines A/C compressor operation, except when the airflow mode selector is
in the OFF, MAX A/C, DEFROST or FLOOR/DEFROST mode. The A/C request button is an integral
part of the HVAC module and cannot be serviced separately.
The recirculated air request button can select recirculated air in any mode except DEFROST, and fresh
air in any mode except MAX A/C or OFF. The recirculated air request button is an integral part of the
HVAC module and cannot be serviced separately.
The rear defog button signals activation of the heated backlight. Under certain conditions, the heated
backlight may be activated automatically by the PCM and Body Control Module (BCM). The rear defog
button indicator may remain off during this time. The rear defog button is an integral part of the HVAC
module and cannot be serviced separately.
Control System Outputs
The Electronic Manual Temperature Control (EMTC) system has 4 system outputs.
Blower Motor Speed
The HVAC module blower motor speed selector varies the blower motor ground circuit resistance by
adding or bypassing series resistance in the blower motor resistor. Increased resistance lowers the
blower motor speed, and lowered resistance increases blower motor speed. When the blower motor is in
the HI (4) position, the blower motor resistor is bypassed.
The blower motor resistor is located on the heater core and evaporator core housing below the glove
compartment.
Temperature Blend Door Position
The temperature blend door actuator moves the temperature blend door on command from the HVAC
module.
The temperature blend door actuator contains a reversible electric motor and a potentiometer. The
potentiometer circuit reports the position of the temperature blend door to the HVAC module. The HVAC
module drives the temperature blend door actuator motor in whichever direction is necessary to move
the temperature blend door to the position set by the vehicle occupants.
The temperature blend door actuator is mounted to the RH side of the heater core and evaporator core
housing and can be serviced separately.
Airflow Mode Door Position
The airflow mode door actuator controls the airflow mode door actuating assembly to position the airflow
mode doors on command from the HVAC module.
The airflow mode door actuator contains a reversible electric motor and potentiometer. The
potentiometer circuit reports the position of the airflow mode doors to the HVAC module. The HVAC
module drives the actuator motor in whichever direction is necessary to move the airflow mode doors to
the position set by the vehicle occupants. The airflow mode door actuating assembly contains a cam and
gear arrangement which transfers the rotation of the airflow mode door actuator to the individual airflow
mode doors.
The airflow mode door actuating assembly is mounted to the LH side of the heater core and evaporator
core housing and can be serviced separately. The airflow mode door actuator is mounted to the airflow
mode door actuating assembly and can be serviced separately.
Air Inlet Mode Door Position
The air inlet mode door actuator moves the air inlet door between the fresh and RECIRC positions on
command from the HVAC module. The air inlet mode door actuator is driven to, and will automatically
stop at, the full RECIRC or full fresh air inlet position and does not require a potentiometer circuit to
monitor its position. The airflow mode door does not stop at any point between the RECIRC or fresh air
inlet position. When the air inlet mode is switched, the airflow mode door actuator is driven by the HVAC
module for 9 seconds, and will stall at the end of travel until the 9 second timer has expired.
The air inlet mode door actuator is mounted to the air inlet duct and can be accessed through the glove
compartment. The air inlet mode door actuator can be serviced separately.

DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Heating and Ventilation
The heating and ventilation system has the following features:
Controls the temperature and, during A/C operation, reduces the relative humidity of the air inside
the vehicle
Delivers heated or cooled air to maintain the vehicle interior temperature and comfort level
Cooling or heating can be adjusted to maintain the desired temperature
The heating and ventilation system includes the following components:
Blower motor
Heater core and evaporator core housing
Heater core
Blower Motor
The blower motor draws air from the air inlet and forces it into the heater core and evaporator core
housing where it is mixed and distributed. The blower motor receives battery voltage at all times when
the ignition is in the RUN position, and is grounded by the HVAC module blower motor switch.
The blower motor is mounted to the LH side of the heater core and evaporator core housing to the right
of the pedal assembly.
Heater Core and Evaporator Core Housing
The heater core and evaporator core housing directs air flow from the blower motor through the
evaporator core (if equipped) and heater core. All air flow from the blower motor passes through the
evaporator core. The air flow is then directed through or around the heater core by an electric motor
actuated temperature blend door. After passing through or around the heater core, the air flow is
distributed to the selected outlet. The air flow mode doors are actuated by a single electric motor using a
cam and gear setup.
Heater Core
The heater core receives a flow of coolant from the engine cooling system through the heater core inlet.
The heater core consists of fins and tubes arranged to extract heat from the engine coolant and transfer
it to air passing through the heater core. The engine coolant is then returned to the engine cooling
system through the heater core outlet.
The heater core is located in the heater core and evaporator core housing.

Removal and Installation
NOTICE: If installing a new Air Conditioning (A/C) compressor due to an internal failure of the old unit,
the following procedures must be carried out to remove contamination from the A/C system. Failure to
remove contamination from the A/C system, if present, will result in poor A/C performance and/or
damage to the new A/C compressor and other components.
If A/C flushing equipment is available, carry out flushing of the A/C system prior to installing a
new A/C compressor. For additional information, refer to Section 412-00 .
If A/C flushing equipment is not available, carry out filtering of the A/C system after a new A/C
compressor has been installed. For additional information, refer to Section 412-00 .
Install a new Thermostatic Expansion Valve (TXV), as directed by the A/C flushing or filtering
procedure.
Install a new receiver/drier as directed by the A/C flushing or filtering procedure.
NOTE: Installation of a new receiver/drier is not required when repairing the A/C system, except when there is
physical evidence of contamination from a failed A/C compressor or damage to the receiver/drier. Damage to
the receiver/drier includes leaks in the receiver/drier, physical damage to the receiver/drier shell or desiccant, or
moisture contamination. Moisture contamination results only from a complete loss of refrigerant and
equalization of the refrigerant system pressure with atmospheric pressure for a period longer than one hour. If
even a slight amount of positive refrigerant pressure is present in the system before repairs are carried out, the
receiver/drier should not be replaced.
NOTE: A new A/C compressor may come equipped with an A/C clutch disc and hub, A/C compressor pulley
and A/C clutch field coil already installed. If these components are not pre-installed, it will be necessary to
transfer these parts from the old A/C compressor to the new compressor prior to installation of the A/C
compressor if suitable for reuse.
1. If flushing of the refrigerant system has not been carried out, recover the refrigerant. For additional
information, refer to Section 412-00 .
2. Remove the compressor-to-condenser discharge line bracket nut.
To install, tighten to 7 Nm (62 lb-in).
3. Remove the 2 A/C compressor fitting nuts and disconnect the fitting.
Discard the O-ring seals and gasket seals.
To install, tighten to 15 Nm (133 lb-in).

harness bracket.
To install, tighten to 24 Nm (18 lb-ft).
8. Remove the A/C compressor.
9. To install, reverse the removal procedure.
Install new O-ring seals and gasket seals.
If filtering of the refrigerant system is not to be carried out, add the correct amount of clean PAG
oil to the refrigerant system. For additional information, refer to the Refrigerant Oil Adding
procedure in Section 412-00 .
10. If filtering of the refrigerant system is not to be carried out, evacuate, leak test and charge the refrigerant
system. For additional information, refer to Section 412-00 .

DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Instrument Cluster and Panel Illumination
Overview
The backlighting system consist of dimmable components and non-dimmable components.
Dimmable Components
The functional dimmable components are:
Driver heated seat switch
Floor shifter
Instrument panel dimmer switch
Front Controls Interface Module (FCIM)
Headlamp switch
HVAC module
Passenger heated seat/ambient lighting switch
Start/stop switch
Steering wheel switches
Instrument Panel Cluster (IPC) (via network message)
Front Control/Display Interface Module (FCDIM) (via network message)
Body Control Module (BCM)
The dimmable backlighting is controlled by the BCM . The dimmable switches and components are
illuminated when the parking lamps are on. The instrument panel dimmer switch is a single detent rocker
switch used to control all dimmable interior illuminated components. The up detent increases dimmable
backlighting intensity and the down detent decreases dimmable backlighting intensity. When the parking
lamps are off, the Instrument Panel Cluster (IPC) is illuminated to full brightness.
Non-Dimmable Components
The functional non-dimmable components are:
Window control switches
The non-dimmable illumination provides backlighting to the window switches when the ignition relay is
energized.

Principles of Operation
Dimmable Backlighting
When the parking lamps are on, the Body Control Module (BCM) monitors the input from the instrument
panel dimmer switch. The BCM sends voltage to the dimmable components based on input received
from the instrument panel dimmer switch.
If a fault is detected by the BCM on the dimmable illumination output circuit, the BCM sets a DTC and
disables the circuit function until the fault is cleared and an ignition cycle takes place.
The BCM also sends a message over the network to the Front Control/Display Interface Module
(FCDIM) and the Instrument Panel Cluster (IPC) to control the backlighting intensity level.
If the receiving module does not receive the backlighting status message from the BCM , or if the data
received is deemed invalid for more than 5 seconds, the receiving module sets a missing message
related DTC in continuous memory and defaults the backlighting to full nighttime intensity.
Non-Dimmable Backlighting
When the ignition relay (located in the Central Junction Box (CJB)) is energized, switched voltage is
supplied to the window control switches.
Field-Effect Transistor (FET) Protection
Field-Effect Transistor (FET) is a type of transistor that when used with module software, monitors and
controls current flow on module outputs. The FET protection strategy prevents module damage in the
event of excessive current flow.
The BCM utilizes an FET protective circuit strategy for many of its outputs, for example a backlighting
illumination output circuit. Output loads (current level) are monitored for excessive current (typically short
circuits) and are shut down when a fault event is detected. A short circuit DTC sets when the fault
occurs.
The FET protection continues to shut off the circuit so long as the fault exists. When the fault is
corrected and the ignition state is cycled off and then back on, the module resets the FET protection and
allows the circuit to function.
The FET protected circuit for the dimmable backlighting system is the dimmable backlighting illumination
circuit.

Refer to Wiring Diagrams Cell 71 , Cluster and Panel Illumination for schematic and connector
information.
Normal Operation
The instrument panel dimmer switch is a rocker style switch with 2 inputs to the Body Control Module
(BCM) to increase or decrease the backlighting illumination. When the instrument panel dimmer switch
is pressed up or down, a ground signal is routed to the BCM .
Based on the ground signal input from the instrument panel dimmer switch, the BCM sends a message
over the network to the modules with backlighting output indicating the backlighting intensity level, and
provides voltage to the hard-wired dimmable illumination sources.
DTC B134E:23 (Switch Illumination Adjustment Control: Signal Stuck low) — a continuous and
on-demand DTC that sets when the BCM detects the instrument panel dimmer switch is stuck or
held low for more than 2 minutes or the increase or decrease control circuits are shorted to
ground. If the instrument panel dimmer switch is stuck low the BCM defaults the backlighting
illumination to full backlighting intensity.

SECTION 413-01: Instrumentation, Message Center, and Warning Chimes
DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 11/03/2010
Information And Message Center
The message center consists of the following:
Instrument Panel Cluster (IPC)
Front Control/Display Interface Module (FCDIM)
The message center is integrated into the FCDIM , which displays message center warning messages,
message center warning indicators and audio information. The message center displays are controlled
by the IPC through messages sent to the FCDIM over the High Speed Controller Area Network (HSCAN) communication bus. The message center constantly monitors different vehicle systems and
displays all warnings and message center functions in the FCDIM . The message center notifies the
driver of potential vehicle concerns by displaying a warning message pertaining to the system in which a
fault has been detected.
Oil Change Minder
The message center provides an oil change minder to inform the driver that an oil change is required.
The calculated interval between oil changes is based on mileage and time. The interval for the oil
change minder is 16,093 km (10,000 miles) or 1 year. The oil change minder can be reset by the driver.
Refer to Message Center Configuration in this section.
Message Center Indicators
The FCDIM displays message center indicators along with warning messages. Many of the message
center indicators use the same or similar iconic representations that are used in the IPC as informational
or warning indicators. For example: the door ajar message center warning indicator is represented by
the same door ajar symbol used in the IPC . The message center indicators are displayed along with
warning messages and may also be accompanied by a warning chime.
System Warning Messages
The system warning messages alert the operator to possible concerns or malfunctions in the vehicle
operating systems. The warning messages that are displayed in the message center are as follows:

Principles of Operation
NOTE: Whenever a network message is suspected as missing or confirmed by a missing message DTC
(U-code), it is important to look for other conditions that may also be present in the Instrument Panel
Cluster (IPC) and throughout the vehicle. Once a DTC sets in the IPC , it may be helpful to review the
complete message list available in Section 418-00 to see what other modules also rely on the same
message and run the self-test for those modules. If the message is missing from other modules, the
same DTC may also be set in those modules. Confirmation of missing messages common to multiple
modules may indicate that the originating module is the source of the concern or the communication
network may be experiencing some problems.
The IPC uses input messages from other modules to control the gauges, informational indicators,
warning indicators, message center and warning chimes over the communication networks. If a required
message is missing or invalid for less than 5 seconds, the gauge or indicator that requires the message
remains at the last commanded state based upon the last known good message. For example, if the
brake status message is missing for less than 5 seconds and the brake warning indicator was
illuminated, the indicator remains in the on state until the next good message is received. If the message
remains missing or invalid for more than 5 seconds, the IPC sets a U-code DTC and the output becomes
a default action for the indicator or gauge. Each indicator or gauge utilizes a different default strategy
depending on the nature of the indication. Refer to the normal operation descriptions located before
each individual pinpoint test for further description of the default action specific to each indicator or
gauge. If the messaged input to the IPC returns at any time, the normal function of the gauge or
indicator resumes.
It is very important to understand:
where the input originates.
all the information necessary in order for a feature to operate.
which module(s) receive(s) the input or command message.
whether the module which received the input controls the output of the feature, or whether it
outputs a message over the communication network to another module.
which module controls the output of the feature.
Instrument Panel Cluster (IPC)
The IPC utilizes a microprocessor to control the gauge and indicator functions. Data is sent to the IPC
over the Medium Speed Controller Area Network (MS-CAN) and the High Speed Controller Area
Network (HS-CAN) bus lines and through hardwired circuitry from individual components. The IPC uses
each input to output an action to the gauges or indicators.
IPC Gateway Function
The IPC acts as a gateway module by receiving information in one format and transmitting it to other
modules using another format. For example, the IPC receives the vehicle speed data from the PCM over
the HS-CAN , converts the data into an MS-CAN message and sends (gateways) the message to other
network modules such as the Body Control Module (BCM). This enables network communication
between modules that do not communicate using the same network ( HS-CAN or MS-CAN ).
IPC Configuration
The IPC contains items that are configurable. Configurable items include customer preference items,
which can be set with a scan tool. The remaining items can be set only through the Programmable
Module Installation (PMI) procedure using As-Built data. Refer to Section 418-01 .
NOTE: When installing a new IPC , it is necessary to upload the module configuration to the scan tool.
Following installation of the IPC download the module configuration from the scan tool into the new IPC .
It is also necessary to carry out key programming and parameter reset whenever a new IPC or PCM is
installed. Refer to Section 419-01B .

Information and Message Center
The message center is integrated into the Front Control/Display Interface Module (FCDIM). The
message center is controlled by the IPC and acts upon much of the same information that is input and
used to operate the IPC gauges, informational indicators, and warning indicators. The FCDIM receives
the message center display information from the IPC over the MS-CAN communication bus.
Whenever conditions are present that require a warning message, the message center replaces the last
selected display with the new warning message. Once the message is reset or cleared, the message
center returns to the last selected display. If multiple warnings are present, the message center displays
each warning for approximately 4 seconds. Warning messages are also generally associated with other
observable IPC indications. For example, when the LH front door is opened, the message center
displays the message DRIVER DOOR AJAR along with the door ajar warning indicator. This allows the
message center to be a more informative supplement to the IPC gauges and indicators.
Warning Chimes
The IPC uses inputs that are both hardwired to individual components and messages that are sent from
other modules over the HS-CAN or MS-CAN to control the warning chime functions.
Warning Chime Characteristics
Each warning chime has unique characteristics that help identify and differentiate one warning chime
from another. The warning chimes use volume, chime frequency, length of time the chime sounds and
the number of chime tones to identify which chime is sounding. The IPC prioritizes the chimes according
to a preset hierarchy programmed into the IPC software. Generally, when more than one chime request
is received by the IPC , the most important chime sounds. If a lower priority chime is currently sounding,
the higher priority request takes over and replaces the lower priority chime.
There are 3 different chimes as listed below:
Repetitive
Single tone
Tick-tock
The following table provides a summary of the chime characteristics including the chime priority:
IPC Chime Characteristics
Chime Name

Belt-Minder®
The Belt-Minder® is configurable. To configure the Belt-Minder®, refer to Belt-Minder®
Deactivating/Activating in this section.
The Belt-Minder® feature supplements the current safety belt warning function and is enabled after the
current safety belt warning is complete. The Belt-Minder® informs the driver that the driver or front
passenger safety belt is unbuckled by intermittently and simultaneously sounding a chime and
illuminating the safety belt warning indicator in the IPC once the vehicle speed has exceeded 9.7 km/h
(6 mph). The Belt-Minder® remains active for 5 minutes from the time it is started. While activated, the
Belt-Minder® chime provides a series of 6 chimes/safety belt warning indicator flash sequences, which
consist of a 1-second chime tone and safety belt warning indicator on/off state. The Belt-Minder® chime
and the safety belt warning indicator sound and flash for 6 seconds, then the chime stops and the safety
belt warning indicator remains on for 30 seconds. The IPC repeats the chime cycle for 5 minutes.
If the vehicle speed drops below 4.8 km/h (3 mph) once the Belt-Minder® chime has activated, the
chime turns off and the safety belt warning indicator remains on. When the vehicle speed exceeds 9.7
km/h (6 mph) again, the Belt-Minder® chime resumes.

Pinpoint Test B: Incorrect Fuel Gauge Indication
Refer to Wiring Diagrams Cell 60 , Instrument Cluster for schematic and connector information.
Normal Operation
The fuel pump module is hardwired to the Instrument Panel Cluster (IPC) between the fuel level signal
circuit and the fuel level signal return circuit. The fuel level sender (float and card) is a variable resistor
attached to the fuel pump module that ranges from 180 ohms ± 4 ohms at empty (E) and 10 ohms ± 2
ohms at full (F). The IPC provides a reference voltage to the fuel pump module on the fuel level input
circuit. As the fuel level changes, a float actuates a variable resistor on the fuel level sensor card and
raises or lowers the fuel level signal voltage depending on the resistance of the fuel level sensor. The
IPC monitors the changes in voltage and commands the fuel gauge with a corresponding movement of
the pointer. If the IPC detects a fault on the fuel level input circuit, fuel level return circuit or the fuel
pump module, the IPC defaults the fuel gauge to the empty (E) position and illuminates the low fuel
warning indicator.

Pinpoint Test F: Incorrect Speedometer Indication
Normal Operation
The Instrument Panel Cluster (IPC) receives the vehicle speed signal from the PCM over the High
Speed Controller Area Network (HS-CAN) communication bus. The vehicle speed data originates with
the wheel speed sensors. The ABS module provides the wheel speed data to the PCM over the HSCAN communication bus. The IPC monitors the vehicle speed input from the PCM and commands the
speedometer with a corresponding movement of the pointer.
The IPC provides a tolerance that allows the speed indication to display between 3% below and 7%
above the actual vehicle speed. This means that with an actual vehicle speed of 96.6 km/h (60 mph), the
speedometer may indicate between 93.7-103.3 km/h (58.2-64.2 mph). Incorrect tire size or tire size
configuration could potentially affect the speedometer accuracy.
If the IPC receives invalid vehicle speed data from the PCM for 5 seconds or less, the IPC defaults the
speedometer to the last setting, based upon the last known good vehicle speed message. If the IPC
does not receive the vehicle speed data from the PCM for more than 5 seconds, the IPC sets DTC
U0100:00 in continuous memory and defaults the speedometer to 0 km/h (0 mph). If the vehicle speed
data received is deemed invalid by the IPC , the IPC sets DTC U0401:68 and defaults the speedometer
to 0 km/h (0 mph).
NOTE: If DTC U0100:00 sets in the IPC , other observable symptoms may be an inoperative tachometer

Pinpoint Test H: The Low Oil Pressure Warning Indicator Is Never/Always On
Refer to Wiring Diagrams Cell 60 , Instrument Cluster for schematic and connector information.
Normal Operation
The Instrument Panel Cluster (IPC) receives the engine oil pressure status from the PCM over the High
Speed Controller Area Network (HS-CAN) communication bus. The PCM provides a reference voltage
to the engine oil pressure switch when the ignition key is in the RUN position. With the engine running
and low or no oil pressure, the engine oil pressure switch closes to ground. The PCM detects the
reference voltage pulled low and sends a request to the IPC to illuminate the low oil pressure warning
indicator. With the engine running and sufficient oil pressure, the engine oil pressure switch opens. The
reference voltage remains unchanged or high and sends a request to the IPC to turn off the low oil
pressure warning indicator.
If the IPC fails to receive the oil pressure status from the PCM for 5 seconds or less, the IPC defaults the
low oil pressure warning indicator to the last state (on or off), based upon the last known good oil
pressure status message. If the IPC fails to receive the oil pressure status from the PCM for more than 5
seconds, the IPC sets DTC U0100:00 in continuous memory and defaults the low oil pressure warning
indicator active (on).
NOTE: If DTC U0100:00 sets in the IPC , other observable symptoms may be an inoperative
speedometer, tachometer, or odometer.

Pinpoint Test I: The Engine Over-Temperature Warning Indicator Is Never/Always On
Normal Operation
The PCM uses the Engine Coolant Temperature (ECT) sensor to measure the engine coolant
temperature. The Instrument Panel Cluster (IPC) receives the engine over-temperature request from the
PCM over the High Speed Controller Area Network (HS-CAN) communication bus. When the PCM
detects high engine coolant temperature, the PCM sends a request to the IPC to illuminate the engine
over-temperature warning indicator.
If the engine coolant temperature status message is missing for 5 seconds or less or if the IPC receives
an invalid engine temperature status message for 5 seconds or less, the IPC defaults the engine overtemperature warning indicator to the last setting (on or off), based upon the last known good request
message.
If the IPC does not receive the engine coolant temperature status message from the PCM for more than
5 seconds, the IPC sets DTC U0100:00 in continuous memory and defaults the engine over-temperature
warning indicator on. If the engine coolant temperature status message is deemed invalid by the IPC for
5 seconds or more, the IPC sets DTC U0401:68 and defaults the engine over-temperature warning
indicator on.
NOTE: If DTC U0100:00 sets in the IPC , other observable symptoms may be an inoperative

Pinpoint Test K: The Charging System Warning Indicator Is Never/Always On
Normal Operation
The charging system indicator is controlled by the Instrument Panel Cluster (IPC) based upon data
received from the PCM over the High Speed Controller Area Network (HS-CAN) communication bus.
When a fault is detected in the charging system, the PCM sends the IPC a request to illuminate the
charging system warning indicator.
If the charging system message is missing or invalid for less than 5 seconds, the charging system
warning indicator remains in the last indication mode (on or off) based on the last known good message
received. If the charging system message is missing for more than 5 seconds, the IPC sets DTC

Pinpoint Test L: The Brake Warning Indicator is Never On
Refer to Wiring Diagrams Cell 60 , Instrument Cluster for schematic and connector information.
Normal Operation
The Instrument Panel Cluster (IPC) uses 3 basic inputs to control the brake warning indicator. The first 2
are the parking brake warning indicator switch and brake fluid level switch. The third is for the Electronic
Brake Distribution (EBD), controlled by the ABS. The parking brake warning indicator switch and brake
fluid level switch are hardwired to the IPC through independent signal circuits. The EBD message is sent
from the ABS module over the High Speed Controller Area Network (HS-CAN) communication bus.
The IPC provides a reference voltage to both the parking brake warning indicator switch and the brake
fluid level switch. When the parking brake is applied, the parking brake warning indicator switch closes
to ground, providing a ground to the IPC and pulling the signal circuit low. When a low brake fluid level
condition exists, the low brake fluid level switch closes to ground pulling the signal circuit low. The IPC
monitors the parking brake and the brake fluid level inputs and illuminates the brake warning indicator
when the parking brake is applied or when the brake fluid level is low. When the ABS module detects a
base brake system concern, other ABS-related or EBD concerns, the ABS module sends a message to
the IPC to illuminate both the ABS warning indicator and the brake warning indicator.
This pinpoint test is intended to diagnose the following:
Wiring, terminals or connectors

Pinpoint Test Q: The Powertrain Malfunction (Wrench) Warning Indicator Is Never/Always On
Normal Operation
The Instrument Panel Cluster (IPC) receives the powertrain malfunction data from the PCM and the
transmission status from the Transmission Control Module (TCM) over the High Speed Controller Area
Network (HS-CAN) communication bus. When a fault condition exists in the PCM, the PCM sends a
request to the IPC to illuminate the powertrain malfunction (wrench) warning indicator. When a fault
occurs in the transmission, the TCM sends a request to the IPC to illuminate the powertrain malfunction
(wrench) warning indicator.
If the powertrain malfunction (wrench) warning indicator request message is missing from the PCM or
TCM for 5 seconds or less, the powertrain malfunction (wrench) warning indicator remains in the last
indication mode (on or off) based upon the last known good request received. If the powertrain
malfunction (wrench) warning indicator request message is missing from the PCM for more than 5
seconds, the IPC sets DTC U0100:00 and defaults the powertrain malfunction (wrench) warning
indicator on. If the powertrain malfunction (wrench) warning indicator request message is missing from
the TCM for more than 5 seconds, the IPC sets DTC U0101:00 and defaults the powertrain malfunction
(wrench) warning indicator on.
NOTE: If U0100:00 sets in the IPC other symptoms may also be present such as an inoperative
speedometer, tachometer or odometer.

Pinpoint Test AD: The Outside Air Temperature Display Does Not Operate Correctly
Refer to Wiring Diagrams Cell 60 , Instrument Cluster for schematic and connector information.
Normal Operation
The Ambient Air Temperature (AAT) sensor is hardwired to the Instrument Panel Cluster (IPC) through
the input and return circuits. The IPC provides a reference voltage to the AAT sensor and monitors the
change in voltage resulting from changes in resistance as determined by outside air temperature. The
IPC is programmed to update the displayed temperature at different rates depending on several criteria
to prevent false temperature displays due to a condition known as heat soaking. Heat soaking is where
the outside air temperature is hotter in the location of the AAT sensor than the actual outside air
temperature.
The IPC uses the last displayed temperature reading, engine coolant temperature and length of time the
engine is off to determine how the display is updated. The IPC stores the last temperature reading at key
off and then compares the value against the current temperature reading. When the current temperature
reading is below the stored temperature reading, the engine has been off for 2.5 hours or the engine
coolant temperature is below 45°C (32°F), the IPC displays the current outside air temperature as
measured by the AAT sensor.
If the IPC fails any of the above criteria, the display is updated according to the following table:
Early Build Update Rate
Vehicle Speed
Display Update Rate
Up to 35 km/h (22 mph)
0.1°C (0.18°F) per minute

DTC B1A68:11 (Ambient Temperature Sensor: Circuit Short To Ground) — a continuous and ondemand DTC that sets if the IPC detects a short to ground on the AAT sensor input circuit. If the
IPC detects a short to ground on the outside air temperature input, the IPC defaults the display to
dashes (----).
DTC B1A68:13 (Ambient Temperature Sensor: Circuit Open) — a continuous and on-demand
DTC that sets if the IPC detects an open on the AAT sensor input circuit. If the IPC detects an

Refer to Wiring Diagrams Cell 60 , Instrument Cluster for schematic and connector information.
Normal Operation
On vehicles without Intelligent Access (IA), the key-in-ignition warning switch is hardwired to the Body
Control Module (BCM) through the key-in-ignition input circuit. When the key is inserted into the ignition
lock cylinder, the key-in-ignition switch opens and removes the ground to the Body Control Module
(BCM). When the BCM detects the key-in-ignition input open with the driver door open, the BCM sends
the IPC a message over the Medium Speed Controller Area Network (MS-CAN) communication bus to
sound the key-in-ignition chime.
On vehicles with IA , the Remote Function Actuator (RFA) module generates an implied key-in-ignition
status from the ignition states and the driver door ajar input. If the vehicle is turned off with the selector
lever out of PARK (P) and the driver door open, the RFA module sends the IPC a message to sound the
key-in-ignition chime.

Pinpoint Test AK: The Safety Belt Warning Chime Is Inoperative/The Belt-Minder® Feature Does
Not Operate
Normal Operation
The Instrument Panel Cluster (IPC) receives the safety belt and Belt-Minder® requests from the
Restraints Control Module (RCM) over the High Speed Controller Area Network (HS-CAN). The safety
belt warning chime sounds for approximately 6 seconds when the driver safety belt is not fastened and
the ignition is changed from the OFF or ACC state to the RUN or START state.
The Belt-Minder® feature supplements the safety belt warning function and is enabled after the safety
belt warning is complete. The Belt-Minder® simultaneously sounds the chime and illuminates the safety
belt warning lamp in the IPC once the vehicle speed has exceeded 5 km/h (3 mph), and remains active
for 5 minutes from the time it is started.
There are 2 Belt-Minder® strategies used and implemented by the IPC as commanded by the RCM .
The 2 strategies are designed to provide an increased intensity level of the chime. Belt-Minder® A
provides 6 one-second sequences of 0.5-second on/0.5-second off for the first minute of the BeltMinder® warning. Belt-Minder® B provides 6 one-second sequences of 0.2-second on/0.2-second off
then 0.3-second on/0.3-second off for the remainder of the Belt-Minder® warning.
NOTE: Make sure the safety belt/Belt-Minder® chime operation is verified with the vehicle moving at
least 9.7 km/h (6 mph).

Principles of Operation
The Battery Junction Box (BJB) supplies the switched and control voltage to the horn relay (part of the
Body Control Module (BCM)). When the driver air bag module is pressed, the horn switch (which is
integrated into the driver air bag module) is closed and ground is supplied to the BCM which is routed
through the clockspring. The horn relay then energizes, sending voltage to the horn, enabling the horn to
sound.
The horn switch is not a single component, but consists of contact points located on the steering wheel
and driver air bag module. The contact points are separated by springs. One set of contacts is part of
the steering wheel itself and the other set is part of a metal plate mounted to the rear of the driver air bag
module. Springs mounted to the metal plate are isolated by plastic seats on the steering wheel. When
the driver air bag module is pressed against the steering wheel, the contacts on the driver air bag
module and the steering wheel touch to complete the circuit.
Anti-Theft Horn
On vehicles equipped with perimeter alarm, the vehicle has a separate anti-theft horn. Refer to Section
419-01A , for information on the perimeter alarm and anti-theft horn.

DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Charging System
The charging system is a negative ground system consisting of:
a generator with an internal voltage regulator.
a charging system warning indicator.
a battery.
circuitry and cables.
a PCM.
The generator is driven by the accessory drive belt. When the engine is started, the generator begins to
generate AC voltage which is internally converted to DC voltage. The DC voltage is controlled by the
voltage regulator (located on the rear of the generator) and supplied to the battery. The PCM controls
the voltage regulator set point, communicating with the generator internal voltage regulator over a
dedicated Local Interconnect Network (LIN) communication circuit.

DIAGNOSIS AND TESTING
2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Principles of Operation
The PCM-controlled charging system, or Smart Charge charging system, determines the optimal voltage
setpoint for the charging system and communicates this information to the voltage regulator. The Smart
Charge charging system is designed to set 1 of 9 DTCs any time a charging system fault is present. All
of the DTCs can set continuous faults, but not all DTCs set as on-demand faults.

This system uses a dedicated Local Interconnect Network (LIN) communication circuit. The generator
uses this LIN circuit to communicate the desired setpoint from the PCM to the voltage regulator. The
generator also uses this LIN circuit to communicate the generator load and error conditions to the PCM.
The PCM simultaneously controls and monitors the output of the generator. When the usage of current
is high or the battery is discharged, the PCM raises engine speed as needed to increase generator
output. The generator charges the battery and at the same time supplies power for all of the electrical
loads that are required. The battery is more effectively charged with a higher voltage when the battery is
cold and a lower voltage when the battery is warm. The PCM uses the measurement from the Intake Air
Temperature (IAT) sensor to adjust the charging voltage according to the battery temperature. The PCM
also uses other inputs to control charging system voltage such as the Vehicle Speed Sensor (VSS) and
Engine Coolant Temperature (ECT) sensor. The voltage setpoint is calculated by the PCM and
communicated to the voltage regulator by the LIN circuit based on the needs of the vehicle and the
operating conditions.
The PCM turns off the generator during cranking to reduce the generator load and improve cranking
speed. Once the engine starts, the PCM slowly increases generator output to desired voltage.
The PCM controls the charging system warning indicator by sending a message over the High Speed
Controller Area Network (HS-CAN) to the Instrument Panel Cluster (IPC) module. The IPC module
controls the charging system warning indication based on the message from the PCM. The IPC module
controls the charging system indication based on the message from the PCM, turning it on or off. If
equipped with a Front Control/Display Interface Module (FCDIM) (message center), the IPC module
displays a CHECK CHARGING SYSTEM message. When the ignition is on and the engine is off on
vehicles equipped with a message center, the CHECK CHARGING SYSTEM message may not be
displayed. For additional information regarding the IPC module, refer to Section 413-01 . For additional
information regarding the FCDIM , refer to Section 415-00 .
Under certain circumstances the charging system may have a concern but still keep the battery charged
and the vehicle running. The LIN normally initiates charging from the PCM, but the generator may
continue charging when a fault is present on this circuit. If the engine is operated at greater than 2,000
rpm momentarily, the generator may self-excite or start charging on its own. The charging system
warning indicator is illuminated and/or CHECK CHARGING SYSTEM message is displayed, and the
generator operates in a default mode (approximately 13.5 volts) until the engine is turned off. When the
engine is restarted and the engine is operated at greater than 2,000 rpm momentarily, the generator
may again self-excite and again the charging system warning indicator is illuminated and/or CHECK
CHARGING SYSTEM message is displayed.

DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Battery and Cables
Vehicles are equipped with a 12-volt, maintenance-free battery.
The battery and cable system consists of the following components:
Battery
Battery cable assembly
Battery tray
The battery is a 12V DC source connected in a negative ground system. The battery case is sealed with 2
vent holes to release gases. The battery has 3 major functions:
Engine cranking power source
Voltage stabilizer for the electrical system
Temporary power source when electrical loads exceed the generator output current
Ford Motor Company strongly recommends that lead-acid batteries be returned to an authorized recycling
facility for disposal.
SECTION 414-01: Battery, Mounting and Cables
DIAGNOSIS AND TESTING
2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Principles of Operation
Battery Eye Operation
The battery eye indicates the state-of-charge of the battery by responding to the specific gravity of a
single battery cell electrolyte. The battery eye has a viewing plate, 2 colored balls of different specific
gravity and a small passage. As the state-of-charge and specific gravity changes, the balls change their
position in the passageway and subsequently display a different color in the viewing eye. The primary
purpose of the battery is to be a quick indicator of state-of-charge for assembly plants and dealership
pre-delivery processes.
The color of the battery eye indicates the approximate state-of-charge.
Red — indicates low state-of-charge.
Yellow/Black — indicates between high and low state-of-charge.
Green — indicates high state-of-charge.
No color can occur after the battery has been in service for several years and some of the plate
material has coated the balls.
A clear battery eye can occur if the battery case becomes damaged and the electrolyte has fallen
below the plates.
NOTE: The battery eye may remain red for a period of time (up to several days), even after the battery is
fully charged, because the acid is not yet fully mixed.
Do not install a new battery based solely on the indication of the battery eye. The battery eye color
simply indicates the battery state-of-charge, not its condition. For example, a red or yellow/black battery
eye usually indicates the battery is discharged, not defective. If the battery eye indicates the battery may
be discharged, it is necessary to recharge the battery before testing its condition.
Charging a Battery
Batteries discharge while the vehicle is on the dealer lot or parked by the customer for an extended
period of time due to normal parasitic key-off loads. Also, vehicles still in dealer inventory or in long-term
storage may be driven short distances with heavy electrical loads. Over a period of time (30 days or
more), this could result in vehicles having shallow or deeply discharged batteries.
Deeply discharged — A battery that is drained over a prolonged period of time, such as an unsold
vehicle or a vehicle in storage, to the point the battery is dead.
Shallow discharge — A battery that is drained by leaving an accessory on for several hours or a
few days and has a very low charge.
The vehicle charging system is designed to supply the electrical power needed to maintain the battery
near full charge during normal vehicle use. The charging system is not capable of bringing a deeply
discharged battery back to near full charge in a short amount of time such as allowing the vehicle to idle
for 15 minutes to "recharge the battery". Discharged batteries should be charged using an external
charger.
NOTE: Battery chargers have improved greatly with the addition of the new generation pulse chargers.
These chargers pulse current into the battery, breaking down the sulfation layer on the battery plates
and generally reduce charging times to less than an hour.
NOTE: Cold batteries will not readily accept a charge. Therefore, batteries should be allowed to warm to
approximately 5°C (41°F) before charging. This may require 4 to 8 hours at room temperature.
The following chart summarizes 2 recommended methods of charging.

DIAGNOSIS AND TESTING
2011 Fiesta Workshop Manual
Procedure revision date: 05/02/2011
Component Test
Battery — Drain Tests
WARNING: Batteries contain sulfuric acid and produce explosive gases. Work in a wellventilated area. Do not allow the battery to come in contact with flames, sparks or burning
substances. Avoid contact with skin, eyes or clothing. Shield eyes when working near the battery
to protect against possible splashing of acid solution. In case of acid contact with skin or eyes,
flush immediately with water for a minimum of 15 minutes, then get prompt medical attention. If
acid is swallowed, call a physician immediately. Failure to follow these instructions may result in
serious personal injury.
NOTICE: To prevent damage to the meter, do not crank the engine or operate accessories that
draw more than 10A.
NOTE: No factory-equipped vehicle should have more than a 50 mA (0.050 amp) draw.
Check for current drains on the battery in excess of 50 mA (0.050 amp) with all the electrical accessories
off and the vehicle at rest for at least 40 minutes. Current drains can be tested with the following
procedure.
NOTE: Many electronic modules draw 10 mA (0.010 amp) or more continuously.
NOTE: Typically, a drain of approximately 1 amp is attributed to an engine compartment lamp, glove
compartment lamp or interior lamp staying on continually. Other component failures or wiring shorts are
located by selectively pulling fuses to pinpoint the location of the current drain. When the current drain is
found, the meter reading falls to an acceptable level. If the drain is still not located after checking all the
fuses, it may be due to the generator. Disconnect the generator and retest.
NOTE: To accurately test the drain on a battery, an in-line ammeter must be used between the negative
battery post and its respective cable. Use of a test lamp or voltmeter is not an accurate method.
1. Make sure the junction box(es)/fuse panel(s) is accessible without turning on the interior lights or
the underhood lights.
2. Drive the vehicle at least 5 minutes and over 48 km/h (30 mph) to turn on and activate the vehicle
systems.
3. Allow the vehicle to sit with the key out of the ignition for at least 40 minutes to allow the modules
to time out/power down.
4. Connect a fused jumper wire (30A) between the negative battery cable and the negative battery
post to prevent modules from resetting.
5. Disconnect the negative battery cable from the negative battery post without breaking the
connection of the jumper wire.
6. NOTE: It is very important that continuity is not broken between the battery and the negative
battery cable when connecting the meter. If this happens, the entire 40-minute procedure must be
repeated.
Connect the battery tester between the negative battery cable and the post. The meter must be
capable of reading milliamps and should have a 10-amp capability.
7. NOTE: If the meter settings need to be switched or the test leads need to be moved to another
jack, the jumper wire must be reinstalled to avoid breaking continuity.
Remove the jumper wire.
8. Note the amperage draw. Draw varies from vehicle to vehicle depending on the equipment
package. Compare to a similar vehicle for reference.
NOTE: If the vehicle sits for an extended period of time and the battery drains, there is the possibility of
a control module staying alive and not going into sleep mode. If a module does stay alive, it can also
result in battery drain. If a module is suspect, isolate individual modules by disconnecting each module
one at a time and note if the excessive draw goes away.
NOTE: For vehicles equipped with aftermarket bodies or boxes which contain electrical connections,
disconnect the aftermarket to factory connections to isolate the body from the chassis.
9. If the current draw is excessive, remove the fuses from the Battery Junction Box (BJB) one at a
time and note the current drop. When the current level drops to an acceptable level after
removing a fuse, the circuit containing the excessive draw has been located. The excessive draw
can be isolated by continuing to pull sub system fuses. Do not reinstall the fuses until testing is
finished. To correctly isolate each of the circuits, all of the fuses may need to be removed, then
install one fuse and note the amperage draw, remove the fuse and install the next fuse. Continue
this process with each fuse.
Once the main circuit is identified, continue to remove the fuses from the Smart Junction
Box (SJB) one at a time and note the current reading. Do not reinstall the fuses until
testing is finished. To correctly isolate each of the circuits, all of the fuses may need to be
removed, then install one fuse and note the amperage draw, remove the fuse and install
the next fuse. Continue this process with each fuse.
10. Check the wiring diagrams for any circuits that run from the battery without passing through the
BJB or the SJB . If the current draw is still excessive, disconnect these circuits until the draw is
found. Also, disconnect the generator electrical connections and retest if the draw cannot be
located. The generator may be internally shorted, causing the current drain.

Principles of Operation
Audio Control Module (ACM)
The Audio Control Module (ACM) can be operated while the key is in RUN or ACC. Additionally, the one
hour mode feature allows the audio system to be operated for 1 hour when the ignition is transitioned to
OFF and the ON/OFF button is pressed.
The ACM can produce its own DTCs, which can be communicated to the scan tool. The ACM
communicates on the Infotainment Controller Area Network (I-CAN), with the Front Control/Display
Interface Module (FCDIM) acting as the gateway to the Medium Speed Controller Area Network (MSCAN).
Front Controls Interface Module (FCIM)
The Front Controls Interface Module (FCIM) is the customer interface to the audio system. It is separate
from the ACM , and utilizes a dedicated Local Interconnect Network (LIN) with the FCDIM to transmit
button press information.
Front Control/Display Interface Module (FCDIM)
The FCDIM is a stand-alone module. It receives messages for all of its displays, which include:
Audio information
Warning and information messages
The FCDIM acts as the gateway between the MS-CAN and the I-CAN .
Satellite Audio
The satellite audio system consists of the ACM , the AM/FM/satellite radio combination antenna, and the
antenna cables. The antenna receives digital audio signals and sends them to the ACM .
Antenna
The fixed-mast antenna receives AM/FM radio waves and sends them to the ACM via the antenna coaxial cable. If the vehicle is equipped with satellite audio, a combination AM/FM/satellite radio antenna is
utilized.
The antenna receives voltage from the ACM in order to amplify the audio signals.
SYNC® System
The SYNC® system allows interaction with several types of customer devices, including mobile phones
and media devices. The system is comprised of the Accessory Protocol Interface Module (APIM), a
microphone, the Universal Serial Bus (USB) cable and port, and the audio input jack. The APIM contains
an on-board Bluetooth® chipset, which enables certain wireless devices to interact with the system.
The APIM consists of 2 internal modules: the Consumer Interface Processor (CIP) and the Vehicle
Interface Processor (VIP). The modules are not replaceable individually, but can be flashed
independently, if required.
The CIP interfaces with all of the customer inputs to the APIM . The CIP contains an analog-to-digital-toanalog converter, as well as the Bluetooth® chipset. Any consumer-available application upgrades that
are available are loaded directly to the CIP through the USB port.
The VIP provides an interface between the CIP and the vehicle. The main functions of the VIP are
controlling the APIM power management and translating both inbound and outbound signals over the
CAN .
The APIM can receive inputs from the following sources:
USB port
Audio input jack
Bluetooth®
The USB port can be used for connecting a media device (such as an iPod®) with the device's available
cable, or for directly plugging in a portable mass storage device (such as a "thumb drive"). When playing
media files stored on a mass storage device, the SYNC® system only plays files that do not have Digital
Rights Management (DRM) protection. The USB port can also be used for uploading vehicle application
upgrades.
The USB port is powered by the APIM , so no external power source is needed to power a device
plugged into the USB port.
The audio input jack can be used for connecting a media device (such as an iPod®) utilizing a 1/8-inch
audio jack. When a device is connected through the audio input jack, only the speaker volume can be
controlled by the ACM . All other functions (such as seek, fast forward, pause, etc.) must be carried out
on the device itself.
The Bluetooth® interface can accommodate both Bluetooth®-enabled mobile phones and Bluetooth®enabled media devices. Any Bluetooth® device used with the SYNC® system must first be paired with
the system before it is operational.
Bluetooth® is a secure, short-range radio frequency that allows devices to communicate wirelessly
through radio waves. The operating range of a Bluetooth® signal is a maximum of 32 feet.
Only one Bluetooth® phone and one Bluetooth® media device can be connected to the system at any
one time. If an additional device of either type is paired with the system and made active, the APIM
disconnects any active connections and establishes a connection with the new device.
It is important to understand that not all mobile phones have the same level of features when interacting
with the SYNC® system. For a list of compatible phones, refer to the SyncMyRide website .
In addition to audio information, metadata may also be sent to the APIM from a device plugged into the
USB port. Metadata consists of such information as artist, album title, song title, and genre. The
metadata is used by the APIM to create indexes that can be used to sort for particular music, based on
customer preference. Not all USB devices send metadata to the APIM ; also, no metadata is transferred
when a device is connected through the audio input jack. When a new media device is connected to the
SYNC® system, the APIM automatically indexes the information. This can take up to several minutes
(depending on the amount of data on the device), and is considered normal operation. When a device
that was previously connected to the SYNC® system is reconnected, the APIM updates the index (rather
than creating a new one), which reduces the amount of time needed to create the index.
The APIM receives both stereo and mono sound inputs, and can also transmit both stereo and mono
sound. The mono function is used to receive the microphone input, and to send sound to the ACM for
voice prompts, the Text-To-Speech (TTS) feature, ringtones, and any audio received through a
connected mobile phone. The TTS feature speaks information so that it does not have to be read from
the display.
The Global Positioning System Module (GPSM) provides vehicle location for real-time traffic reports and
re-routing, and for identifying vehicle location in the event of a collision (part of the e911 feature). The
vehicle location information is broadcast to the APIM over the CAN .
The APIM communicates via the I-CAN and High Speed Controller Area Network (HS-CAN).
Communication with the scan tool is established through the HS-CAN .
Steering Wheel Controls
The steering wheel controls consist of a series of resistors. Each steering wheel controls switch function
corresponds with a specific resistance value within the switch. When a switch is pressed, the FCDIM (or
the APIM ) monitors the change in reference voltage to determine the requested function.
On vehicles equipped with the SYNC® system, the PUSH-TO-TALK (an icon of a person speaking)
switch interfaces directly with the APIM , while the other audio steering wheel controls interface with the
FCDIM .
Audio Input Jack
The audio input jack allows for a portable MP3 audio device to be connected to the vehicle audio
system. When a portable MP3 player is connected, audio from the MP3 audio device can be played
through the vehicle speakers. The audio stream from the audio input jack routes to the APIM if the
vehicle is equipped with the SYNC® system, or directly to the ACM if the vehicle is not equipped with the
SYNC® system.
Audio Signals
Stereo signals contain left and right channel information, and are used for most audio signals.
A mono signal is used for the microphone input to the APIM . A mono signal is also used for the voice
prompts, the TTS feature, ringtones, and any audio received through a connected mobile phone. These
audio signals are output from the APIM to the ACM . The mono and stereo outputs from the APIM utilize
separate circuits.
A digital signal is used to transmit data from a media device connected through the USB port to the
APIM . The APIM then converts the signal to analog and relays the signal to the ACM .
A wireless signal is used to broadcast audio signals from a Bluetooth® device to the APIM . As with a
digital signal sent through the USB port, the APIM converts the wireless audio signal to analog and
relays it to the ACM .
Network Communication
There are numerous messages internal to the audio system. The functions of these message include
(but are not limited to):
Changing the audio source
Updating the FCDIM display
In addition, the numerous messages are utilized by the audio system in conjunction with systems
outside of the audio system. Refer to Section 418-00 for a complete list of network messages.
Inspection and Verification
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical or electrical damage.

If the cause is not visually evident, connect the scan tool to the Data Link Connector (DLC).
5. NOTE: The Vehicle Communication Module (VCM) LED prove-out confirms power and ground
from the DLC are provided to the VCM .
If the scan tool does not communicate with the VCM :
Check the VCM connection to the vehicle.
Check the scan tool connection to the VCM .
Refer to Section 418-00 , No Power To The Scan Tool, to diagnose no power to the scan
tool.
6. If the scan tool does not communicate with the vehicle:
Verify the ignition key is in the ON position.
Verify the scan tool operation with a known good vehicle.
Refer to Section 418-00 to diagnose no response from the PCM.
7. NOTE: Do not press any buttons on the FCIM while the ACM is carrying out the self-test.
Carry out the network test.
If the scan tool responds with no communication for one or more modules, refer to Section
418-00 .
If the network test passes, retrieve and record the continuous memory DTCs.
8. If the DTCs retrieved are related to the concern, go to DTC Charts. For all other DTCs, refer to
the Diagnostic Trouble Code (DTC) Chart in Section 419-10 .

Pinpoint Test B: Poor Reception/Poor Sound Quality/No Sound — Satellite Radio
Normal Operation
Digital signals are received by the satellite radio antenna and sent to the Audio Control Module (ACM)
through the satellite radio antenna cable.
A short to ground in the satellite radio antenna typically has no effect on the antenna signal. However,
an open in the antenna circuit results in no sound from the satellite radio system. A short to voltage in
the antenna circuit can have varying effects on the system.
Obstructions to the antenna line of sight can affect reception, but this is considered normal operation.
Possible obstructions include hills, tall buildings, tunnels, and being parked inside a garage. Make sure
the vehicle is in a clear area, free of obstructions, before testing satellite radio reception.

SECTION 417-01: Exterior Lighting
DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Exterior Lighting
The exterior lighting system consists of the following components:
Headlamp assemblies
Body Control Module (BCM) (located under the glove compartment)
Stoplamp switch
Low beam relay
High beam relay
Reversing lamp relay
Daytime Running Lamps (DRL) relay (if equipped)
Headlamp switch
Multifunction switch
Reversing lamp switch (manual transaxle)
Exterior mirror turn lamps
High mounted stoplamp
Rear lamp assemblies
License plate lamps
Lamp Assembly Condensation
Exterior lamps are vented to accommodate normal changes in pressure. Condensation can be a natural
by-product of this design. When moist air enters the lamp assembly through the vents, there is a
possibility that condensation can occur if the temperature is cold. When normal condensation occurs, a
thin mist forms on the interior of the lens. The thin mist eventually clears and exits through the vents
during normal operation. The amount of time it takes to clear the lens of acceptable mist varies with
ambient humidity and lamp types. Normal condensation clears from any lamp in 48 hours under dry
conditions.
Do not replace a lamp assembly with acceptable levels of condensation such as:
presence of thin mist (no streaks, drip marks or droplets are present)
fine mist covers less than 50% of the lens
Examples of unacceptable moisture (usually caused by a lamp housing leak):
water puddling inside the lamp
large water droplets, drip marks or streaks present on the interior of the lens
Headlamps
The headlamp system is a quad-beam pattern system. It consists of replaceable low and high beam
bulbs. The headlamp assembly has the park/turn indicator and side marker lamp integrated into the
headlamp assembly. The headlamps do not illuminate when the ignition is OFF or in ACC and the
headlamp switch is in the HEADLAMPS ON position.
If the headlamps are in the high beam mode when the headlamp switch is turned off, the BCM defaults
the headlamps to the low beam mode the next time the headlamp switch is placed in the HEADLAMPS
ON position.
Flash-to-Pass and High Beam
When the ignition is in RUN, the high beams are illuminated when the multifunction switch is placed in
the FLASH-TO-PASS position and remain illuminated until the multifunction switch is released.
If the low beams are on when the multifunction switch is placed in the HIGH BEAM position, the high
beams are illuminated in addition to the low beams (high beam mode). The high beams turn off (low
beam mode) when the multifunction switch is placed in the HIGH BEAM position again or the headlamp
switch is switched out of the HEADLAMPS ON position.
Headlamp Exit Delay
When the ignition is OFF or in ACC and the multifunction switch is placed in the FLASH-TO-PASS
position and released, the parking lamps and low beams are illuminated. They remain illuminated until
one of the following occurs:
3 minutes have elapsed with a door open
30 seconds have elapsed after all doors are closed
the multifunction switch is placed in the FLASH-TO-PASS position again
the ignition changes to RUN
With all the doors closed, but within the 30 second delay, opening any door results in the 3 minute timer
restarting.
Daytime Running Lamps (DRL)
If the vehicle is equipped with Daytime Running Lamps (DRL), the BCM is configured for this feature.
The DRL feature illuminates the low beam headlamps at a reduced intensity when the ignition is in RUN
and the headlamp switch is in the OFF position.
The DRL feature is inactive when the flash-to-pass feature is active.
The DRL feature is not a programmable parameter for this vehicle.
Stoplamps
The stoplamp switch is located on the brake pedal assembly. The stoplamps illuminate when the brake
pedal is applied. The rear lamps are combination stop/turn lamps on 4-door vehicles.
Turn Signal/Hazard Lamps
The front turn signal lamps are located within the headlamp assemblies. The rear lamps on 4-door
vehicles share functionality with the stoplamps (combination stop/turn lamps). If equipped, there are turn
signal lamps located within the exterior mirrors.
When the multifunction switch is place in the LH or RH LANE CHANGE position (first detent down or up)
and released, the turn signals flash 1 or 3 times. This setting is programmed by the driver from the
center display (Front Control/Display Interface Module (FCDIM)) in the instrument panel.
When the multifunction switch is placed in the LH or RH TURN position (second detent down or up), the
BCM cycles the voltage on and off approximately 75 times per minute. If a front or rear turn bulb is
inoperative, the BCM cycles the voltage on and off approximately 150 times per minute.
The hazard flasher switch is integrated into the Front Controls Interface Module (FCIM). When the
hazard flasher switch is pressed, the BCM cycles the voltage on and off to all the turn lamps
approximately 75 times per minute.
Parking Lamps
The BCM supplies voltage to the parking lamps when demanded. The parking lamp system includes the
following:
Front parking lamps
Front side marker lamps
Rear parking lamps
License plate lamps
Reversing Lamps
When the transaxle is placed in REVERSE (R) with the ignition in RUN, the reversing lamp relay
(automatic transaxle) or the reversing lamp switch (manual transaxle) provides voltage to the reversing
lamps. The reversing lamps are located within the rear lamp assemblies.

Principles of Operation
Exterior Lighting
The Body Control Module (BCM) monitors the headlamp switch position by sending voltage signals on
multiple circuits to the headlamp switch. There is one circuit for each headlamp switch position. At any
given time, one of the signal circuits is switched to ground to indicate the headlamp switch position.
If, when the ignition is in RUN, the BCM does not detect any active inputs from the headlamp switch or if
the BCM detects multiple headlamp switch input circuits short to ground, the BCM turns the parking
lamps and headlamps on and keeps them on until the ignition is transitioned OFF.
If either situation occurs, the BCM cannot be ruled immediately as being at fault. This is normal
behavior of the BCM design as a fault has been detected with the inputs from the headlamp switch.
Flash-to-Pass and High Beam
The BCM monitors the multifunction switch for a flash-to-pass or high beam request. With the ignition in
RUN and the multifunction switch in the FLASH-TO-PASS position, the BCM energizes the high beam
relay until the multifunction switch is released.
If the low beams are on when the BCM detects the multifunction switch is in the HIGH BEAM position,
the BCM energizes the high beam relay to provide voltage to the high beams (high beam mode). The
BCM defaults to low beam mode if the headlamps are turned off using the headlamp switch or the
ignition transitions out of RUN.
Field-Effect Transistor (FET) Protection
A Field-Effect Transistor (FET) is a type of transistor that, when used with module software, monitors
and controls current flow on module outputs. The FET protection strategy prevents module damage in
the event of excessive current flow.
The BCM utilizes a FET protective circuit strategy for many of its outputs (such as a turn lamp output
circuit). Output loads (current level) are monitored for excessive current (typically short circuits) and are
shut down when a fault event is detected. A short circuit DTC sets when the fault event occurs.
The circuit remains off until the fault is corrected and the ignition is cycled off and then back on, the
module resets the FET protection and allows the circuit to function.
The FET protected circuits for the headlamp system are the low and high beam relay coil ground
circuits.

Normal Operation
The low beams do not turn on unless the ignition is in RUN. The Body Control Module (BCM) monitors a
circuit that is provided voltage when the ignition is in RUN.
Voltage is provided at all times to the switch and coil sides of the low beam relay. When the BCM
detects the headlamp switch in the HEADLAMPS ON position, the BCM provides ground for the low
beam relay coil. When the low beam relay energizes, voltage is routed through Battery Junction Box
(BJB) fuses 14 (10A) (LH low beam) and 15 (10A) (RH low beam) to the headlamps.
DTC B10A8:12 (Low Beam Relay: Circuit Short To Battery) — a continuous and on-demand DTC
that sets when the BCM detects a short to voltage from the low beam relay coil ground controlled
circuit.
DTC B10A8:14 (Low Beam Relay: Circuit Short To Ground Or Open) — a continuous and ondemand DTC that sets when the BCM detects an open from the low beam relay coil ground

Normal Operation
Voltage is provided at all times to the switch and coil sides of the high beam relay. The Body Control
Module (BCM) sends a voltage signal to the multifunction switch to monitor for a high beam request. The
multifunction switch routes the voltage signal to ground when placed in the HIGH BEAM position. When
the headlamps are on and the BCM detects a request for the high beams, the BCM provides ground for

Pinpoint Test C: The Low Beams Are Always On
Refer to Wiring Diagrams Cell 85 , Headlamps for schematic and connector information.
Normal Operation
The Body Control Module (BCM) sends voltage signals to the headlamp switch through the headlamp
switch input circuits (off, parking lamps, headlamps). At any given time, the headlamp switch routes one
of the input circuits to ground, indicating the headlamp switch position to the BCM . When the BCM
detects the headlamp switch in the HEADLAMPS ON position, the BCM provides ground for the low
beam relay coil. When the low beam relay energizes, voltage is routed through Battery Junction Box
(BJB) fuses 14 (10A) (LH low beam) and 15 (10A) (RH low beam) to the headlamps.
If the BCM detects multiple or no active headlamp switch inputs, the BCM defaults the exterior lamps on.
Vehicles equipped with Daytime Running Lamps (DRL) utilize a separate relay in conjunction with the
existing headlamp circuitry to illuminate the low beams at a reduced intensity when the ignition is in
RUN.

Pinpoint Test D: The High Beams Are Always On
Refer to Wiring Diagrams Cell 85 , Headlamps for schematic and connector information.
Normal Operation
Voltage is provided at all times to the switch and coil sides of the high beam relay. The Body Control
Module (BCM) sends two voltage signals to the multifunction switch. One is to monitor for a high beam
request and the other for a flash-to-pass request. The multifunction switch routes the corresponding
voltage signal to ground when placed in the HIGH BEAM or FLASH-TO-PASS position. When the
headlamps are on and the BCM detects a request for the high beams or flash-to-pass feature, the BCM
provides ground for the high beam relay coil. When the high beam relay energizes, voltage is routed
through Battery Junction Box (BJB) fuses 12 (10A) (LH high beam) and 13 (10A) (RH high beam) to the
headlamps.
DTC B1007:92 (High-Beam Headlamp Switch: Performance Or Incorrect Operation) — an ondemand DTC that sets when the BCM detects a short to ground from the high beam or flash-topass request input circuits.
DTC B109A:14 (High Beam Relay: Circuit Short To Ground Or Open) — a continuous and ondemand DTC that sets when the BCM detects a short to ground from the high beam relay coil

Diagnostic System (IDS)
software with appropriate
hardware, or equivalent scan

NUD105-R025D or equivalent
Principles of Operation
The Body Control Module (BCM) controls the Daytime Running Lamps (DRL) by energizing the DRL
relay when the ignition is in RUN and the headlamp switch is not in the HEADLAMPS ON position.
When the DRL relay is energized, voltage is routed through a resistor wire to the low beam relay. The
voltage passes through the low beam relay to the existing circuitry for the low beams. The voltage
passes through a resistor wire to illuminate the low beams at reduced intensity.
The DRL is not a programmable parameter for this vehicle.
Field-Effect Transistor (FET) Protection
A Field-Effect Transistor (FET) is a type of transistor that, when used with module software, monitors
and controls current flow on module outputs. The FET protection strategy prevents module damage in
the event of excessive current flow.
The BCM utilizes a FET protective circuit strategy for many of its outputs (such as a turn lamp output
circuit). Output loads (current level) are monitored for excessive current (typically short circuits) and are
shut down when a fault event is detected. A short circuit DTC sets when the fault event occurs.
The circuit remains off until the fault is corrected and the ignition is cycled off and then back on, the
module resets the FET protection and allows the circuit to function.
The FET protected circuit for the DRL system is the DRL relay coil ground circuit.

(VCM) and Integrated
Diagnostic System (IDS)

Principles of Operation
The Body Control Module (BCM) monitors the multifunction switch position by sending voltage signals to
the multifunction switch and the Front Controls Interface Module (FCIM). When the multifunction switch
is in the LH or RH TURN position, or the hazard flasher lamp switch is pressed, that input signal is
routed to ground.
When the BCM receives a request for a turn signal or hazard lamp function, the BCM supplies on/off
voltage to the appropriate turn lamps.
On 4-door vehicles, turn relays interrupt the stoplamp switch output and allow the BCM to control voltage
to the combination stop/turn lamps.
The timed on/off cycle for the turn lamps is determined by the BCM and is set to flash approximately 75
times per minute if both the front and rear turn lamps operate correctly. If an individual turn lamp is
inoperative, the BCM flashes the remaining turn lamp approximately 150 times per minute.
The timed on/off cycle for the hazard lamp function is set to flash all the turn lamps approximately 75
times per minute.
Field-Effect Transistor (FET) Protection
A Field-Effect Transistor (FET) is a type of transistor that, when used with module software, monitors
and controls current flow on module outputs. The FET protection strategy prevents module damage in
the event of excessive current flow.
The BCM utilizes a FET protective circuit strategy for many of its outputs (such as a turn lamp output
circuit). Output loads (current level) are monitored for excessive current (typically short circuits) and are
shut down when a fault event is detected. A short circuit DTC sets when the fault event occurs.
The circuit remains off until the fault is corrected and the ignition is cycled off and then back on, the
module resets the FET protection and allows the circuit to function.
The FET protected circuits for the turn lamp system are the turn relay coil ground circuits and the front
and rear turn lamp voltage supply circuits.

Principles of Operation
The Body Control Module (BCM) monitors the headlamp switch position by sending voltage signals on
multiple circuits to the headlamp switch. There is one circuit for each headlamp switch position. At any
given time, one of the signal circuits is switched to ground to indicate the headlamp switch position.
If, when the ignition is in RUN, the BCM does not detect any active inputs from the headlamp switch or if
the BCM detects multiple headlamp switch input circuits short to ground, the BCM turns the parking
lamps and headlamps on and keeps them on until the ignition is transitioned OFF.
If either situation occurs, the BCM cannot be ruled immediately as being at fault. This is normal
behavior of the BCM design as a fault has been detected with the inputs from the headlamp switch.
When the BCM receives an input from the headlamp switch indicating a request for the parking lamps,
the supplies voltage to the exterior lamps.
Field-Effect Transistor (FET) Protection
A Field-Effect Transistor (FET) is a type of transistor that, when used with module software, monitors
and controls current flow on module outputs. The FET protection strategy prevents module damage in
the event of excessive current flow.
The BCM utilizes a FET protective circuit strategy for many of its outputs (such as a turn lamp output
circuit). Output loads (current level) are monitored for excessive current (typically short circuits) and are
shut down when a fault event is detected. A short circuit DTC sets when the fault event occurs.
The circuit remains off until the fault is corrected and the ignition is cycled off and then back on, the
module resets the FET protection and allows the circuit to function.
The FET protected circuits for the parking lamp system are the LH rear (and license plate lamps), the
RH rear, LH front, RH front and front marker lamp voltage supply circuits.

GENERAL PROCEDURES
2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Headlamp Adjustment
Special Tool(s)
Vision 100 Headlamp Aimer
196-00005 or equivalent
Headlamp Aiming
NOTE: For the photometric aiming procedure, refer to the appropriate photometric headlamp aimer
instruction manual.
NOTE: Mechanical aimers cannot be used with VOR- or VOL-type headlamps.
NOTE: Consult your state vehicle inspection manual for recommended tolerance ranges for visual
aiming.
NOTE: Horizontal aim is not adjustable.
1. The headlamp aiming procedure depends on what type of beam pattern the headlamp is
equipped with. Vehicles may come equipped with visually optically aligned left (VOL) or visually
optically aligned right (VOR) headlamps. To identify the headlamp beam pattern, look on the
headlamp lens. Molded in small letters on the headlamp lens is one of the following:
VOL and SAE
VOR and SAE
2. Once the headlamp beam pattern is identified, aim the headlamps using one of the following
methods as applicable.
Photometric aimers can aim VOL- and VOR- headlamps. This is the preferred method of
headlamp aiming.
Visual or screen method aiming can be used to aim VOL- and VOR- headlamps.
Mechanical aimers cannot be used with VOR- or VOL-type headlamps. Aerodynamic
lamps that can be aimed mechanically have 3 nibs molded into the lens of the lamp.
3. Before starting headlamp adjustment:
check that the vehicle is on level ground.
check the tire inflation.
check that no other load is in the vehicle other than a half tank of fuel.
check that the headlamps are clean.
check for correct headlamp operation.
if the vehicle is equipped with air suspension, make sure that the switch is on.
4. NOTE: The vertical wall or screen must be a minimum of 2.4 m (8 ft) wide.
Park the vehicle on a level surface approximately 7.6 m (25 ft) from the vertical wall or screen
directly in front of it.
5. NOTE: The center of the lamp is marked either on the lens (circle, crosshair or other mark) or on
the bulb shield internal to the lamp (crosshair or other mark).
Mark a horizontal reference line on the vertical wall or screen.
1. Measure the center of the headlamp height to ground and record the measurement.
2. Make a 2.4 m (8 ft) horizontal mark (using masking tape) on the vertical wall or screen at
the same distance from the ground as previously recorded.
6. NOTE: This procedure should be done in a dark environment to effectively see the headlamp
beam pattern.
Turn on the low beam headlamps to illuminate the wall or screen and open the hood.
7. NOTE: The appearance of the VOR beam pattern may vary between vehicles.
For VOR-type headlamps, locate the top edge of this high intensity area a distinct horizontal
cutoff in the beam pattern on the wall or screen. Using the adjusting screw, adjust the headlamp
until the top edge of this cutoff is even with the horizontal reference line.
8. For VOL-type headlamps, locate the distinct cutoff in the left portion of the beam pattern. Using
the adjusting screw, adjust the headlamp until the edge of this cutoff is positioned 50.2 mm (2 in)
below the horizontal reference line.
1. Horizontal reference line.
2. Top edge of the beam pattern.
3. High intensity zone.

SECTION 417-02: Interior Lighting
DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Interior Lighting
The interior lighting system consists of the following components:
Interior/map lamps
Luggage compartment lamp
Door ajar switches (integrated into the door latches)
Luggage compartment lid/liftgate ajar switch (integrated into the luggage compartment lid/liftgate
latch)
Ambient lighting module (located under the center console)
Ambient lighting switch (integrated into the passenger heated seat switch)
Body Control Module (BCM)
The interior lighting system consists of up to 3 subsystems:
Courtesy lamps
Demand lamps
Ambient lighting
Battery Saver
NOTE: Time-out is 10 seconds if the vehicle is in Factory mode or 0 seconds if the vehicle is in
Transport mode.
The provides automatic shut-off of the courtesy and demand lamps after a time-out period when the
ignition is OFF. A timer in the BCM starts when any of the following occur:
the ignition is changed to OFF
any door or luggage compartment lid/liftgate becomes ajar
the UNLOCK button of the transmitter is pressed
a door is unlocked using a key
the door lock switch is pressed
When 10 minutes (30 minutes for demand lamps) have elapsed, the automatically shuts the voltage off
to the lamps. The timer restarts (voltage is restored if the BCM is in battery saver mode) if any of the
following occurs:
the ignition is changed out of OFF
any door, luggage compartment lid or liftgate becomes ajar
the UNLOCK button of the transmitter is pressed
a door is unlocked using a key
the door lock switch is pressed
Courtesy Lamps
The courtesy lamp subsystem consists of the interior/map lamps, the door ajar switches and the BCM .
The turns the courtesy lamps on when a door is opened or when an unlock signal is received from the
Remote Keyless Entry (RKE) transmitter.
Illuminated Entry/Exit
The illuminated entry and exit features provide temporary illumination of the parking lamps, the
dimmable backlighting, the ambient backlighting and the courtesy lamps. Refer to the following table for
additional information.
NOTE: An arbitrator (software programming) within the determines which actions take precedence over
others (for example, an open door keeps the courtesy lamps on even when a command to lock the
doors is received).
NOTE: For vehicles without Intelligent Access (IA), the timer for the backlighting and ambient lighting is
reset to 25 seconds when the key is inserted or removed from the ignition lock cylinder.

The theater lighting option ramps-up the courtesy lamps over 0.7 second when courtesy lamp activation
is requested. The theater lighting feature ramps-down the courtesy lamps over 1.7 seconds when
interior lighting deactivation is requested by any feature other than the panic alarm or battery saver.
Demand Lamps
The demand lamps subsystem consists of the map/reading lamps and the luggage compartment lamp
(sedan) or cargo lamp (5-door) lamp. The energizes the battery saver relay to supply voltage to the
demand lamps when the battery saver feature is not active.
Ambient Lighting
The ambient lighting LEDs illuminate the cup holders (front and rear) and the front and rear footwell
areas. The ambient lighting subsystem consists of the ambient lighting switch, the ambient lighting
module, and the harness with hardwired LEDs located within the floor console and under the instrument
panel footwell areas. The ambient lighting is operational when the ignition is in any state other than OFF
(the exception is when it is used in conjunction with the illuminated entry/exit features). The ambient
lighting switch cycles the LEDs through 7 different color combinations or to turn the ambient lighting off.

DIAGNOSIS AND TESTING
2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Interior Lighting
Special Tool(s)
Fluke 77-IV Digital Multimeter
FLU77-4 or equivalent
Vehicle Communication Module
(VCM) and Integrated
Diagnostic System (IDS)
software with appropriate
hardware, or equivalent scan
tool
Flex Probe Kit
NUD105-R025D or equivalent
Principles of Operation
The Body Control Module (BCM) supplies voltage (and ground for the courtesy lamps) to the interior
lighting system. The interior lighting system illuminates the courtesy lamps to enhance visibility of the
interior when a vehicle door is ajar. The BCM controls all interior lighting functions and timing by
monitoring inputs from the door ajar switches, luggage compartment lid/liftgate ajar switch, door lock
switch, input from the Remote Keyless Entry (RKE) system and the ignition state.
The voltage supply circuit to the BCM for the interior lamps is also used for the horn.
Ambient Lighting
The ambient lighting module provides voltage and ground to the LEDs. The ambient lighting switch is an
input to the ambient lighting module. With each press of the ambient lighting switch, the ambient lighting
module cycles through a different color variation or turns the ambient lighting feature off. There are 3
different color (red, blue and green) LEDs housed within each LED assembly. By illuminating various
color combinations, the LEDs are able to produce 7 different colors of ambient light. The module retains
the last color setting between ignition cycles.
Field-Effect Transistor (FET) Protection
A FET is a type of transistor that, when used with module software, monitors and controls current flow
on module outputs. The FET protection strategy prevents module damage in the event of excessive
current flow.
The BCM utilizes a FET protective circuit strategy for many of its outputs (such as a turn lamp output
circuit). Output loads (current level) are monitored for excessive current (typically short circuits) and are
shut down when a fault event is detected. A short circuit DTC sets when the fault event occurs.
The circuit remains off until the fault is corrected and the ignition is cycled off and then back on, the
module resets the FET protection and allows the circuit to function.
The FET protected circuits for the interior lighting system are the interior lamp voltage supply, courtesy
lamp ground and ambient lighting module voltage supply circuits.

door latch), which is routed to ground when the door is closed (the door ajar switch is closed when the
door is closed). When the door is opened, the signal to ground is interrupted, indicating an open door to
the BCM . When the BCM determines a door is open, the battery saver relay energizes (if not already
energized) to supply voltage to the interior lamps and the BCM provides ground to the courtesy lamps.
The demand lamp system (map lamps) uses the interior lamps ground circuit.

SECTION 418-00: Module Communications Network
DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 08/11/2011
Communications Network
Multiplexing is a method of sending 2 or more signals simultaneously over a single circuit. Multiplexing allows 2
or more electronic modules (nodes) to communicate simultaneously over a twisted-wire pair [data (+) and data
(-)] network. The information or messages that can be communicated on these wires consists of commands,
status or data. The advantage of using multiplexing is to reduce the weight of the vehicle by reducing the
number of redundant components and electrical wiring.
The vehicle has 2 module communication networks connected to the Data Link Connector (DLC) and
communicate with the scan tool. The communication networks are:
High Speed Controller Area Network (HS-CAN)
Medium Speed Controller Area Network (MS-CAN)
The Infotainment Controller Area Network (I-CAN) is connected to the DLC , but the I-CAN modules
communicate with the scan tool over the MS-CAN . The Front Control/Display Interface Module (FCDIM) is
used as a gateway module for the messages to transfer between the scan tool and the modules on the I-CAN .

Network Termination
The CAN uses a network termination circuit to improve communication reliability. The network termination of
the CAN bus occurs inside the termination modules by termination resistors. Termination modules are located
at either end of the bus network. As network messages are broadcast in the form of voltage signals, the
network voltage signals are stabilized by the termination resistors. Each termination module has a 120 ohm
resistor across the positive and negative bus connection in the termination module. With 2 termination modules
on each network, and the 120 ohm resistors located in a parallel circuit configuration, the total network
impedance, or total resistance is 60 ohms.
Network termination improves bus message reliability by stabilizing bus voltage, and eliminating electrical
interference.
Gateway Module
The IPC is the gateway module, translating HS-CAN to MS-CAN and vice versa. The FCDIM is the gateway
module, translating MS-CAN to I-CAN and vice versa, allowing a message to be distributed throughout the
three networks. The IPC and the FCDIM are the only modules on this vehicle that have this ability.

Principles of Operation
The High Speed Controller Area Network (HS-CAN) operates at a maximum data transfer speed of 500 Kbps
and is designed for real time powertrain information transfer and control. Modules on the HS-CAN communicate
using bussed messages. The HS-CAN uses an unshielded twisted pair cable, data bus (+) and data bus (-)
circuits. In addition to scan tool communication, the HS-CAN allows sharing of information between all modules
on the network.
The Medium Speed Controller Area Network (MS-CAN) operates at a maximum data transfer speed of 125
Kbps for bus messages and is designed for general information transfer. Modules on the MS-CAN
communicate using bussed messages. The MS-CAN uses an unshielded twisted pair cable, data bus (+) and
data bus (-) circuits. In addition to scan tool communication, the MS-CAN allows sharing of information between
all modules on the network.
The Infotainment Controller Area Network (I-CAN) operates at a maximum data transfer speed of 500 Kbps and
is designed for real time audio and multimedia information transfer and control. Modules on the I-CAN
communicate using bussed messages. The I-CAN uses an unshielded twisted pair cable, data bus (+) and data
bus (-) circuits. The I-CAN allows sharing of information between all modules on the network. The I-CAN is
connected to the Data Link Connector (DLC), but the I-CAN modules communicate with the scan tool over the
MS-CAN . The Front Control/Display Interface Module (FCDIM) is used as a gateway module for the messages
to transfer between the scan tool and the modules on the I-CAN .
Controller Area Network (CAN) Fault Tolerance
NOTE: The oscilloscope traces below are from the Integrated Diagnostic System (IDS) oscilloscope taken
using the IDS pre-configured CAN settings. The traces are for both data (+) and data (-) taken simultaneously
(2-channel) at a sample rate of 1 mega-sample per second (1MS/s) or greater.
Traces below are viewed at 500mV per division (vertical axis) and 20 microseconds (20μs) per division
(horizontal axis). Readings taken with a different oscilloscope vary from those shown. Compare any suspect
readings to a known good vehicle.
Normal CAN Operation
The data (+) and data (-) circuits are each regulated to approximately 2.5 volts during neutral or rested network
traffic. As messages are sent on the data (+) circuit, voltage is increased by approximately 1.0 volt. Inversely,
the data (-) circuit is reduced by approximately 1.0 volt when a message is sent.
Successful communication of a message can usually be identified by the slight spike at the end of a message
transmission. Any signals that are significantly different than the normal CAN waveform may cause network
DTCs (U-codes) to set or may cause a complete network outage.
CAN Circuits Shorted Together
In the event the data (+) and data (-) circuits become shorted together, the signal stays at base voltage (2.5V)
continuously and all communication capabilities are lost.
CAN (+) Circuit Shorted To Ground
In the event the data (+) circuit becomes shorted to ground, both the data (+) and data (-) circuits are pulled low
(0V) and all communication capabilities are lost.
CAN (-) Circuit Shorted To Ground
In the event the data (-) circuit becomes shorted to ground, the data (-) circuit is pulled low (0V) and the data (+)
circuit reaches near-normal peak voltage (3.0V) during communication but falls to 0V instead of normal base
voltage (2.5V). Communication may continue but at a degraded level.
CAN (+) Circuit Shorted To Battery Voltage
In the event the data (+) circuit becomes shorted to battery voltage, the data (+) circuit is pulled high (12V) and
the data (-) circuit falls to abnormally high voltage (above 5V) during communication and reaches battery
voltage (12V) for peak voltage. Communication may continue but at a degraded level.
CAN (-) Circuit Shorted To Battery Voltage
In the event the data (-) circuit becomes shorted to battery voltage, both the data (+) and data (-) circuits are
pulled high (12V) and all communication capabilities are lost.
CAN Circuit Signal Corruption
Rhythmic oscillations, inductive spikes or random interference can disrupt the network communications. The
corruption signal source may be outside electrical interference such as motors or solenoids or internal
interference generated from a module on the network. In some cases, an open in either the data (+) or data (-)
circuit to a network module may cause the module to emit interference on the one circuit which is still
connected. The trace shown is an example of a "sawtooth" pattern transmitted from a module with one open
network circuit.
Other corruptions may be present when a module is intermittently powered up and down. The module on power
up may initiate communication out of sync with other modules on the network causing momentary
communication outages.
Controller Area Network (CAN) Multiplex Messages
Modules on the CAN utilize simultaneous communication of 2 or more messages on the same network circuits.
The following chart summarizes the messages sent and received on the network.
CAN Module Communication Message Chart
NOTE: This chart describes the specific HS-CAN and MS-CAN messages broadcast by each module, and the
module(s) that receive the message.
NOTE: For the I-CAN , message mapping is not essential to diagnostics as the symptoms arising from a
message error are all related to the audio system. For audio system concerns, refer to Section 415-00 .

3. Connect the scan tool to the DLC .
NOTE: Make sure to use the latest scan tool software release.
NOTE: The Vehicle Communication Module (VCM) LED prove-out confirms power and ground
from the DLC are provided to the VCM .
If the Integrated Diagnostic System (IDS) does not communicate with the VCM :
Check the VCM connection to the vehicle.
Check the scan tool connection to the VCM .
GO to Pinpoint Test R , to diagnose No Power To The Scan Tool.
4. Establish a scan tool session.
NOTE: The scan tool first attempts to communicate with the PCM, after establishing
communication with the PCM, the scan tool then attempts to communicate with all other modules
on the vehicle.
If an IDS session cannot be established with the vehicle, ( IDS may state "No communication can
be established with the PCM"):
Choose "NO" when the scan tool prompts whether or not to retry communication.
Enter either a PCM part number, tear tag or calibration number to identify the vehicle and
start a session (the PCM part number and 4-character tear tag are printed on the PCM
label).
GO to Pinpoint Test A , to diagnose The PCM Does Not Respond To The Scan Tool.
5. Carry out the network test.
If the network test passes, retrieve and record the continuous memory DTCs and proceed to Step
6.
If the network test fails, GO to Symptom Chart to diagnose the failed communication network.
If a module fails to communicate during the network test, GO to Symptom Chart .
6. Retrieve and review the DTCs.
If the DTCs retrieved are related to the concern, go to DTC Charts. Follow the non-network DTC
diagnostics (B-codes, C-codes, P-codes) prior to the network DTC diagnostics (U-codes).
If no DTCs related to the concern are retrieved, GO to Symptom Chart .
DTC Charts
NOTE: Network DTCs (U-codes) are often a result of intermittent concerns such as damaged wiring or low
battery voltage occurrences. Additionally, repair procedures such as module reprogramming often set network
DTCs. Replacing a module to resolve a network DTC is unlikely to correct the concern. To prevent repeat
network DTC concerns, inspect all network wiring, especially connectors. Test the vehicle battery, refer to
Section 414-01 .

software with appropriate
hardware, or equivalent scan
tool
Principles of Operation
Configurable modules accommodate a variety of vehicle options, eliminating the need for many unique
modules for one vehicle line. These modules must be configured when replaced as part of a repair
procedure. Configurable modules should not be exchanged between vehicles since the settings are
unique to each vehicle. Failure to configure a new module may result in incorrect operation and/or DTCs
setting.
The following are the 3 different methods of configuration:
Programmable Module Installation (PMI)
Module reprogramming (flashing)
Programmable parameters
Some modules do not support all 3 methods.
Definition of Terms
The following are definitions of configuration terms:
Programmable Module Installation (PMI)
PMI is a scan tool process which configures settings in a new module. Data used for the PMI process is
automatically downloaded from the original module and stored when a scan tool session is started. If this
data cannot be retrieved from the module being replaced, the scan tool may prompt for As-Built data
entry or display a list of parameter values that need to be manually selected. Some modules are
reprogrammed during PMI when a strategy/calibration update is available. To carry out PMI , refer to
Programmable Module Installation (PMI) in this section.
NOTE: It is important for the scan tool to identify the vehicle and obtain configuration data prior to
removing any modules. The new module must be able to communicate with the scan tool in order to
carry out PMI .
Module Reprogramming
Module reprogramming (also referred to as flashing) is a scan tool process which updates the
strategy/calibration in a module. Reprogramming a module with the same level of software will not
improve module operation or repair a hardware failure. Module reprogramming is automatically carried
out during PMI when a later strategy/calibration is available.
NOTE: Module reprogramming should be limited to circumstances where a published TSB procedure
recommends doing so.
NOTE: A module cannot communicate with other modules on the communication network while being
reprogrammed. Clear any network communication DTCs which may have been set in other modules
during the reprogramming process.
Accessory Protocol Interface Module (APIM) Programming
Accessory Protocol Interface Module (APIM) programming is a process that updates the APIM
Consumer Interface Processor (CIP) and Vehicle Interface Processor (VIP) software. The VIP
programming updates the calibration files in the portion of the APIM that interfaces with the Controller
Area Network (CAN). The CIP programming updates calibration files in the portion of the APIM that
interfaces with mobile phones and other customer devices.
APIM programming uses the Vehicle Communication Module (VCM) to read and program the VIP
software through the Data Link Connector (DLC). A web-based On-Line Automotive Service Information
System (OASIS) application is used to read the CIP software via a Universal Serial Bus (USB) cable
between the scan tool and the vehicle's USB port. Both the VCM and the OASIS application must be
running on the scan tool during APIM programming. To carry out APIM programming, refer to Accessory
Protocol Interface Module (APIM) Programming in this section.
Programmable Parameters
Programmable parameters are customer preference items that may be modified by the dealer via scan
tool or in some cases, modified by the customer following a procedure listed in the vehicle Owner's
Literature. While many configuration options may exist for a module, only a few of these options are
programmable parameters.
Adaptive Learning and Calibration
Some modules require a separate learning procedure be carried out if replaced as part of a repair
procedure. For adaptive learning and calibration instructions, refer to the specific module removal and
installation procedures.
Vehicle Identification (VID) Block
Some PCMs contain a memory area called a Vehicle Identification (VID) block. The PCM VID block
commonly stores powertrain configuration items such as Vehicle Identification Number (VIN), tire size,
axle ratio, and whether or not the vehicle is equipped with speed control.
Module Address
A unique module address is assigned to each module on the network for identification.
As-Built Data
As-Built data is a VIN -specific module configuration record. During vehicle build, the configuration from
all modules is downloaded and stored in the As-Built database. As-Built data does not reflect customer
preference items that have been changed from the default state. These items need to be changed using
programmable parameters after the module is configured.
NOTE: It is not necessary to obtain As-Built data unless directed to do so by the scan tool. This data
may be accessed from the technician service publication web site.

SECTION 419-01A: Anti-Theft — Perimeter
DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Anti-Theft
The perimeter anti-theft alarm system consists of the following:
Anti-theft alarm horn (inside the luggage compartment on the passenger side in 4-door sedans.
Underneath the left rear D-pillar trim in 5-door hatchbacks.)
Door ajar input
Door lock control switch input
Door disarm switch (part of the driver door latch)
Hood switch (part of the hood latch)
Liftgate/luggage compartment ajar input
Remote Keyless Entry (RKE) transmitter
Turn signals
Body Control Module (BCM)
The perimeter alarm system protects the vehicle from unauthorized entry by sounding the horn and
flashing the turn signals at regular intervals when the system is armed and any door, the hood, or
liftgate/luggage compartment is opened without using the key in the driver door lock cylinder, the
Remote Keyless Entry (RKE) transmitter, or the Intelligent Access (IA) feature.
Arming the Perimeter Alarm
The perimeter alarm is ready to arm any time when the ignition is off. Any of the following pre-arms the
alarm system:
pressing the LOCK button on a programmed RKE transmitter.
pressing the door lock control switch to the LOCK position with the door open, then closing the
door.
turning the driver door lock cylinder to the LOCK position.
Once the system is pre-armed, there is a 11-second countdown before the perimeter alarm is armed.
Each entry point to the vehicle (hood, door, or liftgate/luggage compartment) are armed separately and
must be closed before that entry point begins the 11-second countdown to become armed. If all entry
points (hood, doors, and liftgate/luggage compartment) are closed, the turn signals flash indicating all
entry points are entering the 11-second countdown.
Disarming the Perimeter Alarm
The perimeter alarm can be disarmed by:
pressing the UNLOCK button on a programmed RKE transmitter.
pressing the liftgate/luggage compartment release button on a programmed RKE transmitter.
turning the driver door lock cylinder to the unlock position.
using a programmed key to transition the ignition to the RUN mode.
unlock the driver door or all doors using the IA feature.
Intelligent Access (IA) Key Disable
For security reasons, when the perimeter alarm enters an armed state, theRemote Function Actuator
(RFA) module searches the interior of the vehicle for any programmed IA keys. If the RFA module
detects any programmed IA keys inside the vehicle when the perimeter alarm is armed, it disables the IA
key. The RKE and the IA functions of that key still operate, but the RFA module ignores any start
command associated with that key. The disabled IA key is enabled when the perimeter alarm is
disarmed by pressing the RKE unlock button on the IA key, using the IA feature to unlock the doors, or
by using the mechanical key blade in the door lock cylinder to unlock the doors.

Principles of Operation
The Body Control Module (BCM) controls the operation of the perimeter alarm based on the following
inputs:
door ajar switches
hood ajar
driver door lock cylinder
door lock control switch
Passive Anti-Theft System (PATS) input
and the Remote Keyless Entry (RKE) transmitters
On vehicles equipped with Intelligent Access (IA) the BCM receives the RKE transmitter and IA input
from the Remote Function Actuator (RFA) module over the Medium Speed Controller Area Network
(MS-CAN). If the perimeter alarm is armed, and the BCM receives an input indicating an unauthorized
entry into the vehicle or the ignition is turned to the RUN position without a programmed PATS key, the
BCM activates the perimeter alarm. When the perimeter alarm is activated, the anti-theft horn sounds
and the turn signals flash in regular intervals. The traffic horn does not sound during a perimeter alarm
event.
Battery Disconnect
If the battery is disconnected and then reconnected, the perimeter alarm remains in the same state
(disarmed, pre-armed, armed, or activated) it was prior to the battery disconnect.
Alarm Event PIDs
The BCM has PIDs available that show what caused the last alarm events. The 5 BCM alarm event
PIDs are ALARM_1 through 5. The cause for the most recent alarm activation is always listed in the first
alarm event PID. These PIDs display what caused the alarm to activate and can be a very useful tool
when trying to identify the cause of a false alarm activation.
Inspection and Verification
1. Verify the customer concern.
2. Visually inspect for obvious signs of electrical damage.

Pinpoint Tests
Pinpoint Test A: The Alarm System Does Not Arm/Disarm From The Driver Door Lock Cylinder
Refer to Wiring Diagrams Cell 117 , Remote Keyless Entry and Alarm for schematic and connector
information.
Normal Operation
The Body Control Module (BCM) monitors the driver door lock through the set/reset switch (part of the
driver door latch) and the set and reset input circuits. When a key in the door lock cylinder is turned to
the LOCK position it grounds the set circuit signaling the BCM to arm the alarm. When a key in the door
lock cylinder is turned to the UNLOCK position it grounds the reset circuit signaling the BCM to disarm
the alarm. The driver door latch uses a dedicated ground circuit for the door ajar and set/reset switches.
B10B1:92 (Cabin Set/Reset Switch: Performance or Incorrect Operation) — a continuous and ondemand DTC that sets when the BCM detects a short to ground on the driver door lock cylinder
set or reset input circuits.

Pinpoint Test D: The Alarm System Does Not Arm/No Turn Signal Flash Confirmation
Normal Operation
The Body Control Module (BCM) controls the perimeter alarm system and based on inputs either arms,
disarms or activates the alarm. When the alarm is activated, the BCM sounds the anti-theft horn and
flashes the turn signals at regular intervals. The BCM receives inputs for the door lock status, hood ajar,
door ajar and the liftgate/luggage compartment lid ajar. The BCM also receives signals from the Remote
Keyless Entry (RKE) transmitters.
For the perimeter alarm to arm and provide a flash of the turn signals, the following conditions must be
met:
ignition must be off
the hood closed
all doors closed
the liftgate/luggage compartment closed
an electronic lock command received from a Remote Keyless Entry (RKE) transmitter, driver door
lock cylinder, or door lock control switch (front door opened and then shut after lock is pressed).
An Intelligent Access (IA) lock command received (if equipped with IA )
Once all the conditions are met, the alarm system enters a pre-arm phase and begins a 11-second
countdown. The perimeter alarm arms after 11 seconds have passed and no unlock command is
received or any hood, door or liftgate/luggage compartment is opened.
The perimeter alarm is triggered when any door, the hood, or the liftgate/luggage compartment is
opened without first receiving an electronic unlock command from a RKE transmitter, the driver door lock
cylinder, or an IA unlock. The perimeter alarm also activates if the ignition is turned to RUN without a
valid Passive Anti-Theft System (PATS) key read received.
This pinpoint test is intended to diagnose the following:

SECTION 419-01B: Anti-Theft — Passive Anti-Theft System (PATS)
DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Anti-Theft
Passive Anti-Theft System (PATS) Without Intelligent Access (IA)
Passive Anti-Theft System (PATS) consists of the following components:
Anti-theft indicator
Integrated Keyhead Transmitter (IKT)
PATS transceiver (located next to the ignition lock cylinder)
Instrument Panel Cluster (IPC)
PCM
PATS protects the vehicle from theft by preventing the engine from starting unless a programmed IKT is
used.
Passive Anti-Theft System (PATS) Operation
PATS prevents the engine from starting by disabling the starter relay and fuel injector operation. If an
unprogrammed key is used or if there is a PATS system concern, the anti-theft indicator in the IPC
flashes rapidly and the engine will not start. PATS cannot disable an already running engine.
Passive Anti-Theft System (PATS) Keys
The vehicle comes equipped from the factory with two programmed IKTs . The IKT incorporates both the
PATS and Remote Keyless Entry (RKE) transmitter functions in a single device. The key programming is
a two step procedure. PATS information is programmed into the IPC and then the RKE transmitter is
programmed into the BCM . The IPC accepts the programming of an unlimited number of keys, and the
BCM accepts the programming of up to 8 keys. Refer to Key Programming Using Diagnostic Equipment
in this section for PATS programming, and then refer to Remote Keyless Entry (RKE) Transmitter
Programming in Section 501-14 to program the RKE transmitter.
Passive Anti-Theft System (PATS) With Intelligent Access (IA)
The Passive Anti-Theft System (PATS) consists of the following components:
IA key
Front passive start antenna (located in the front of the floor console just below the HVAC controls)
Center passive start antenna (located on the bottom of the rear of the floor console)
Rear passive start antenna (located behind the rear seat bottom cushion)
PATS /backup transceiver (located in the steering column)
Remote Functions Receiver (RFR) module (located on the top of the headliner in the front)
Remote Function Actuator (RFA) module
PCM
Intelligent Access (IA) Passive Anti-Theft System (PATS) Operation
The IA PATS prevents the ignition from transitioning out of the off mode unless a programmed IA key is
detected inside the vehicle. If no programmed key is detected inside the vehicle when the START/STOP
button is pressed, KEY NOT DETECTED is displayed in the Front Control/Display Interface Module
(FCDIM). PATS cannot turn the ignition off or disable an already running engine.
Intelligent Access (IA) Keys
The vehicle is equipped with 2 IA keys. The IA key incorporates both the PATS and the RKE transmitter
functions in a single device. The IA key must be located inside the vehicle for vehicle starting. During
key programming procedures, the PATS and RKE transmitter of an IA key are both programmed into the
RFA module. The RFA module accepts programming of up to 8 IA keys. Refer to Key Programming
Using Diagnostic Equipment in this section for key programming information.
PATS /Backup Transceiver
The PATS /backup transceiver is located in the steering column in the same location as a vehicle
equipped without IA . If the vehicle does not start normally, place the IA key next to the steering column
shroud and attempt to start the vehicle.
Intelligent Access (IA) with Push Button Start Ignition Modes
The IA feature does not require a conventional key to enter or start the vehicle. Once inside the vehicle,
the operator activates one of the ignition modes using the brake pedal (automatic transaxle) or clutch
pedal (manual transaxle) and the push button start (START/STOP) switch, as follows:

Principles of Operation
Passive Anti-Theft System (PATS) Operation
The Passive Anti-Theft System (PATS) is controlled by the Instrument Panel Cluster (IPC). There are
two main checks that PATS performs before allowing the engine to start. If either of these checks fail,
PATS does not allow the engine to start and the anti-theft indicator in the IPC flashes rapidly. These two
checks are the IPC verifying the PCM ID to make sure it matches the PCM ID stored in memory and to
verify that a programmed key was used to turn the ignition to the RUN or START position.
The first check is initiated when the ignition is turned to the RUN or START position. Once the IPC
determines the ignition has been turned to the RUN or START position, it generates a challenge
message. It sends this challenge message to the PATS transceiver on the transmit (TX) circuit. The
transceiver in turn reads the key and generates a response message that is sent back to the IPC on the
receive (RX) circuit. The engine does not start if the message received from the transceiver does not
match a key stored in the IPC memory.
Once the IPC determines a programmed key was used to turn the ignition to RUN or START, the IPC
sends the PCM a challenge message over the High Speed Controller Area Network (HS-CAN). When
the PCM receives the challenge message, it generates a response and sends it back to the IPC . The
engine does not start if the response from the PCM does not match the response in the IPC memory.
If both the key verification and PCM ID pass, PATS is enabled the engine is allowed to start. PATS
cannot disable an engine that has already been started.
Spare Key Programming
The customer spare key programming allows spare keys to be programmed (up to a maximum of 8) to
the IPC without having to use a scan tool. Two programmed keys are required to carry out the
procedure. Refer to Key Programming — Program a Key Using Two Programmed Keys in this section
for the customer spare key programming procedure.

Pinpoint Test D: DTC U0167:00 or U0426:00
Normal Operation
When the ignition is turned to the RUN or START position, the Instrument Panel Cluster (IPC) and the
PCM send each other their ID over the High Speed Controller Area Network (HS-CAN). Each module
then checks the ID it receives and compares with the ID stored in memory. If the IDs are missing or
invalid, Passive Anti-Theft System (PATS) is disabled and does not allow the engine to start.
DTC U0167:00 (Lost Communication With Vehicle Immobilizer Control Module: No Sub Type
Information) — a continuous DTC that sets when the PCM does not receive any PATS data from
the IPC over the HS-CAN . The target ID is only sent once per key cycle and within milliseconds
of the ignition being turned to the RUN or START position.
DTC U0426:00 (Invalid Data Received From Vehicle Immobilizer Control Module: No Sub Type
Information) — a continuous DTC that sets when the PCM does not receive the expected target
ID from the IPC over the HS-CAN . The target ID is only sent once per key cycle and within
milliseconds of the ignition being turned to the RUN or START position. This DTC also sets if a

Principles of Operation
Push Button Start Components
Passive Start Antennas
There are three passive start antennas. The passive start antennas are hardwired to the Remote Function
Actuator (RFA) module and, when activated by the RFA module, they transmit a low frequency signal that
activates an Intelligent Access (IA) key.
Passive Anti-Theft System (PATS)/Backup Transceiver
The PATS /backup transceiver is used as a backup device. If the vehicle fails to start conventionally, an IA key
can be held in close proximity to the transceiver to allow the vehicle to start. The transceiver is wired to the RFA
module and when activated it sends out a signal to activate an IA key. Once the key is activated, it sends a
signal back to the transceiver which is then sent to the RFA module.
Remote Functions Receiver (RFR) Module
The Remote Functions Receiver (RFR) module is hardwired to the RFA module and is a receiving antenna that
receives the high frequency signals from an IA key. It also receives the signals from an Remote Keyless Entry
(RKE) command.
IA Key
The IA receives the low frequency signals from the passive start antennas. When the IA key is activated by one
of the low frequency signals, it sends out a high frequency signal that is received by the RFR module. The IA
key also contains a key blade that is used to enter the vehicle as a backup.
Start/Stop Switch
The start/stop switch is a momentary contact switch that is hardwired to the RFA module. When the switch is
pressed, it signals the RFA module that there is a request to either switch the ignition on or start the engine.
Push Button Start Operation
The Passive Anti-Theft System (PATS) function is controlled by the RFA module and PCM.
When the start/stop switch is pressed, the RFA module initiates the key initialization sequence by activating the
3 interior IA passive start antennas. Each passive start antenna transmits a low frequency signal approximately
1 m (3 ft) radius of each antenna. If an IA key is within range of 1 of the 3 interior passive start antennas, the IA
key is activated. Once the IA key is activated, it sends the PATS identification code to the Remote Functions
Receiver (RFR) module via a high frequency signal. The RFR module interprets the high frequency signal from
the IA key and sends the information to the RFA module over a dedicated network. If the RFA module
determines that a programmed IA key is inside the vehicle, it allows the ignition to be transitioned out of off.
When the ignition is turned on and the PCM initializes, the RFA module and the PCM exchange their IDs over
the High Speed Controller Area Network (HS-CAN). If the RFA module receives a valid key code and the
correct ID from the PCM, PATS is enabled and allows the engine to start. If PATS disables the engine from
starting, the anti-theft indicator in the IPC flashes rapidly.
PATS and the RKE system share the operation of several components including the IA key and the RFR
module. If there is a concern with either of these components, both PATS and the RKE system are affected.
Refer to Section 501-14 for information on the RKE and IA features.
The RFA module also controls the ignition modes and in conjunction with the PCM controls the starting system.
If there is a concern with starting system or the ignition modes, and PATS has been eliminated as the cause,
refer to Section 303-06 for a starting system concern or Section 211-05 for the ignition modes.
Backup Starting
The vehicle can experience a PATS no start ff there is a failure of any passive start antenna, the battery in the
IA key, or the RFR module. However, in the event of one of these failures, the IA key can be placed next to the
PATS /backup transceiver (located in the steering column) to allow the vehicle to start. If a programmed IA key
is near the steering column shroud when the PATS /backup transceiver is activated, it activates the IA key and
the identification code is sent back to the RFA module.
Interior Passive Start Antenna Ranges
NOTE: Some brands/types of mobile phone or laptop computer chargers may cause interference that could
lead to a PATS no-start if the IA key is within a few inches of the charger. If a concern is observed, move the IA
key away from the charger and attempt to start the vehicle.
There are 3 passive start antennas that are used solely for the purpose of starting the vehicle. They are located
in the front of the floor console, in the rear of the floor console, and behind the rear lower seat cushion. When
activated, each antenna sends out a low frequency signal with an approximate range of 1 m (3 ft). A
programmed IA key must be in range of 1 of the 3 antennas for PATS to operate.
If an IA key is placed in the far outside edges of the interior, like above a sun visor or in a door map pocket, the
vehicle might experience a no-start. If the IA key is located in one of these areas and there is a no-start
condition, move the IA key out of the area and attempt to start the vehicle. If the key is outside the range of a
passive start antenna, KEY NOT DETECTED is displayed in the Front Control/Display Interface Module
(FCDIM).
Key Outside Vehicle Message
The KEY OUTSIDE VEHICLE message is displayed in the FCDIM when the engine has been started or the
ignition is in the RUN mode and an IA key is no longer detected inside the vehicle. The RFA module activates
all passive start antennas to search the inside of the vehicle for an IA key anytime a door or luggage
compartment lid/liftgate is opened and then closed. This strategy prevents the IA key from being separated
from an already running vehicle. If an IA key is no longer in the vehicle, the ignition remains in RUN and the
engine continues to run. If the start/stop switch is pressed to turn the ignition off, the engine can be re-started
without an IA key present inside the vehicle for approximately 10 seconds. After 10 seconds an IA key has to
be present to start the engine or transition the ignition out of off. If the driver door is opened during the 10second countdown, the fast restart feature is disabled, and an IA key is needed to start the engine again.

Pinpoint Test G: DTC B10D7:81
Refer to Wiring Diagrams Cell 117 , Remote Keyless Entry and Alarm for schematic and connector information.
Normal Operation
When the START/STOP switch is pressed, the Remote Function Actuator (RFA) activates all 3 passive start
antennas, which send out a low frequency signal. Each passive start antenna has an approximate range of 1 m
(3 ft) and are placed in different locations to provide full coverage inside the vehicle. If an Intelligent Access (IA)
key is within range of a passive start antenna, the low frequency signal activates the IA key. When the IA key is
activated it sends a high frequency signal to the Remote Functions Receiver (RFR) module. The RFR module
communicates with the RFA module. If the RFA module determines that a programmed IA key is in the vehicle,
it allows the ignition to transition out of off or let the engine start.
NOTE: Some brands/types of mobile phone or laptop computer chargers may cause interference that could
lead to a Passive Anti-Theft System (PATS) no-start if the IA key is within a few inches of the charger. If a

Pinpoint Test H: DTC B10D9:87, B10E6:11, or B10E6:12
Refer to Wiring Diagrams Cell 112 , Passive Anti-Theft System for schematic and connector information.
Normal Operation
The Remote Function Actuator (RFA) module supplies voltage to the Passive Anti-Theft System (PATS)
transceiver. If the RFA module does not passively detect an Intelligent Access (IA) key, it activates the PATS
transceiver as a backup to try and detect a key. The RFA module also activates the PATS transceiver for key
programming procedures. The RFA module starts the key interrogation sequence by supplying voltage to the
transceiver. Once the transceiver is powered up, the RFA module generates a signal and sends that signal to
the transceiver on the transmit (TX) circuit. When the transceiver receives the signal from the RFA module, it
reads the PATS key and generates a challenge response to the RFA module signal and sends this response on
the receive (RX) circuit.
DTC B10D9:87 ( PATS Transponder: Missing Message) — sets when the RFA module does not receive
a response from the PATS transceiver.
DTC B10E6:11 ( PATS Power Supply: Circuit Short To Ground) — sets when the RFA module detects a
short to ground on the PATS transceiver voltage supply circuit.

Pinpoint Test I: DTC B10D6:62 or U0100:87
Normal Operation
When the ignition is transitioned out of off, the Remote Function Actuator (RFA) module checks the PCM ID
and compares It with the PCM ID that is stored in the RFA module memory. If the RFA module does not receive
the PCM ID or the ID is invalid, Passive Anti-Theft System (PATS) is disabled and does not allow the engine to
start.
DTC B10D6:62 ( PATS Enable Status: Signal Compare Failure) — sets when the RFA module does not
receive the expected target ID from the PCM over the High Speed Controller Area Network (HS-CAN).
The target ID is only sent one time per ignition cycle and is sent within milliseconds of the ignition being
transitioned out of off.
DTC U0100:87 (Lost Communication With ECM/PCM "A": Missing Message) — sets when the RFA
module does not receive the target ID from the PCM over the HS-CAN . The target ID is only sent one

Pinpoint Test J: DTC U201F:00 or U201F:13
Refer to Wiring Diagrams Cell 117 , Remote Keyless Entry and Alarm for schematic and connector information.
Normal Operation
When the Intelligent Access (IA) key is activated by one of the low frequency passive start antennas, the
transmitter in the IA key sends a radio signal to the Remote Functions Receiver (RFR) module. The RFR
module then communicates the command to the Remote Function Actuator (RFA) module, and the RFA
module either switches the ignition to the requested mode or starts the engine.
The RFR module receives voltage from Central Junction Box (CJB) fuse 7 (7.5A) and has a dedicated ground
circuit. The RFR module sends all Remote Keyless Entry (RKE) and IA key information and requests to the
RFA module through a dedicated single circuit network.
In the event of a failure with the RFR module, the vehicle experiences a no-start unless the IA key is placed
near the Passive Anti-Theft System (PATS) transceiver.
DTC U201F:00 (External Receiver: No Sub Type Information) — sets when the RFA module has lost
communication with the RFR module.
DTC U201F:13 (External Receiver: Circuit Open) — sets when the RFA module has lost communication

Pinpoint Test K: The Vehicle Does Not Start With The Intelligent Access (IA) Key In Certain Areas Within
The Vehicle
Refer to Wiring Diagrams Cell 112 , Passive Anti-Theft System for schematic and connector information.
Normal Operation
During each vehicle start sequence, when the START/STOP switch is pressed, the Remote Function Actuator
(RFA) activates all 3 passive start antennas, which send out a low frequency signal. Each passive start antenna
has an approximate range of 1 m (3 ft) and are placed in different locations to provide full coverage inside the
vehicle. If an Intelligent Access (IA) key is within range of a passive start antenna, the low frequency signal
activates the IA key. When the IA key is activated it sends a high frequency signal to the Remote Functions
Receiver (RFR) module. The RFR module communicates with the RFA module. If the RFA module determines
that a programmed IA key is in the vehicle, it allows the ignition to transition out of off or let the engine start.
There are certain areas inside the vehicle where the IA key may not be detected and the message center
displays KEY NOT DETECTED. If the IA key is in the far outside edges of the interior (like in a door map pocket
or above a sun visor) it might not be detected. Move the IA key to a different location and try to start the vehicle
again.
NOTE: Some brands/types of mobile phone or laptop computer chargers may cause interference that could
lead to a Passive Anti-Theft System (PATS) no-start if the IA key is within a few inches of the charger. If a
concern is observed, move the IA key away from the charger and attempt to start the vehicle.
DTC B10C7:1F (Interior Trunk Antenna: Circuit Intermittent) — a DTC that sets when an open or short is
detected on one of the circuits to the rear passive start antenna.

Pinpoint Test L: The Vehicle Does Not Start/Unable To Transition The Ignition Out Of OFF
Normal Operation
During each vehicle start sequence, when the START/STOP switch is pressed, the Remote Function Actuator
(RFA) activates all 3 passive start antennas, which send out a low frequency signal. If an Intelligent Access (IA)
key is within range of a passive start antenna, the low frequency signal activates the IA key. When the IA key is
activated it sends a high frequency signal to theRemote Functions Receiver (RFR) module. The RFR module
communicates with the RFA module. If the RFA module determines that a programmed IA key is in the vehicle,
it allows the ignition to transition out of off or let the engine start.
The vehicle experiences a PATS no-start in the event there is a failure of any passive start antenna, the battery
in the IA key, or the RFR module. However, in the event of one of these failures, the IA key can be placed next
to the PATS transceiver (located in the steering column) to allow the vehicle to start. The PATS transceiver
activates an IA key if it is placed in close proximity. The PATS transceiver is hardwired to the RFA module.
Once the RFA module determines that a programmed IA key is inside the vehicle and receives a request to
start the engine, it communicates with the PCM over the High Speed Controller Area Network (HS-CAN). Once
the RFA module and the PCM communicate, the RFA module checks the ID of the PCM and compares it with
the module ID stored in its own memory. If the RFA module and PCM IDs match then the PATS enables the
starter relay and fuel injectors and allows the engine to start.
The IA key disable feature prevents the engine from starting or the ignition from transitioning out of off if the IA
key has been disabled. For more information on the IA key disable feature, refer to Section 419-01A .

Pinpoint Test N: DTC U0167:00 or U0426:00
Normal Operation
When the ignition is turned to the RUN or START mode, the Remote Function Actuator (RFA) module and the
PCM send each other their ID over the High Speed Controller Area Network (HS-CAN). Each module then
checks the ID it receives and compares with the ID stored in memory. If the IDs are missing or the IDs are
invalid, Passive Anti-Theft System (PATS) is disabled and does not allow the engine to start.
DTC U0167:00 (Lost Communication With Vehicle Immobilizer Control Module: No Sub Type
Information) — a continuous DTC that sets when the PCM does not receive any PATS data from the
RFA module over the HS-CAN . The target ID is only sent once per key cycle and within milliseconds of
the ignition being turned to the RUN or START mode.
DTC U0426:00 (Invalid Data Received From Vehicle Immobilizer Control Module: No Sub Type
Information) — a continuous DTC that sets when the PCM does not receive the expected target ID from
the RFA module over the HS-CAN . The target ID is only sent once per key cycle and within milliseconds

SECTION 419-03: Cruise Control
DESCRIPTION AND OPERATION
2011 Fiesta Workshop Manual
Procedure revision date: 05/13/2010
Cruise Control
The cruise control system consists of the following components:
Clutch pedal cruise control deactivator switch (manual transaxle only)
Cruise control deactivator switch
Cruise control indicator
Cruise control switch
Electronic Throttle Body (ETB)
Instrument Panel Cluster (IPC)
Stoplamp switch
PCM
During normal driving, the vehicle speed may vary slightly from the set speed due to road conditions.
The vehicle speed may vary or fluctuate when driving up and down a steep hill. If the vehicle speed
decreases more than 16 km/h (10 mph) below the set speed, the cruise control disengages.
For manual transaxle vehicles, it is normal for the engine rpm to increase slightly and then drops off
slowly when the clutch pedal is pressed during operation.

Principles of Operation
The cruise control system is controlled by the PCM and the Instrument Panel Cluster (IPC). The cruise
control system is designed to maintain a selected vehicle speed between 30 km/h (18 mph) and the
maximum limited vehicle speed. The cruise control system is controlled by the steering wheel mounted
switches (ON/OFF, SET+, SET-, and CAN/RES), brake pedal inputs and the clutch pedal cruise control
deactivator switch (manual transaxle). The cruise control switches are hard-wired to the IPC . The IPC
sends a High Speed Controller Area Network (HS-CAN) network message to the PCM to control the
cruise control system.
The clockspring provides the electrical interface between the steering column wiring and the cruise
control switches in the steering wheel.
The cruise control functions include:
turning on the cruise control system.
setting and maintaining the desired vehicle speed.
accelerating the vehicle speed.
coasting down to a lower speed.
resuming the prior vehicle speed.
turning off the cruise control system.
Pressing and releasing the ON switch turns the cruise control system on. Pressing and releasing the
SET+ or SET- switch while the vehicle is traveling at the desired speed activates the cruise control
system. The cruise control indicator illuminates green to indicate the cruise control system is active.
Tapping the SET+ or the SET- switch while in the set mode, increases or decreases the maintained
vehicle speed by 1.6 km/h (1 mph) per tap. If the respective switch is pressed and held, the vehicle
speed continues to accelerate or decelerate until the switch is released.
Pressing and releasing the OFF switch, or turning the ignition switch to the OFF position, turns the
cruise control system off. Applying the brake pedal or clutch pedal (manual transaxle) puts the cruise
control system into standby mode.
The CAN/RES switch has a dual function for cancelling or resuming the cruise control system. Pressing
the CAN/RES switch, when the cruise control system is active moves the system into the standby mode
(cancel function). The cruise control indicator turns off. Pressing the CAN/RES switch when the cruise
control system is in the standby mode causes the vehicle to accelerate to the last set speed (resume
function). The cruise control indicator illuminates to indicate the system is reactivated. Resume does not
function if the OFF switch is pressed, the ignition switch is in the OFF position, or if the current vehicle
speed is below the minimum operational speed.
The stoplamp switch and the cruise control deactivator switch are electrical inputs controlling the cruise
control system. The stoplamp switch is a normally open switch that is hard-wired to the PCM. When the
brake pedal is applied, the switch closes and applies a voltage signal to the PCM, deactivating the cruise
control. The cruise control deactivator switch is a normally closed switch that is hard-wired to the IPC .
When the brake pedal is applied, the switch opens and removes the ground signal from the IPC . The
IPC sends a HS-CAN network message to the PCM to signal that the brake pedal is applied. The PCM
compares the inputs from the stoplamp switch and the cruise control deactivator switch. If a deviation
occurs, the PCM sets a DTC and the cruise control system is deactivated.
The clutch pedal cruise control deactivator switch is used on vehicles equipped with a manual transaxle.
When the clutch pedal is pressed with the cruise control system engaged, the normally open switch
closes and provides a ground signal to the IPC . The IPC sends a HS-CAN network message to the
PCM to deactivate the cruise control system and place it in standby mode.
The inputs to the PCM are:
Digital Transmission Range (TR) sensor (automatic transaxle)
Cruise control switch(es) (networked from the IPC )
Clutch pedal cruise control deactivator switch (manual transaxle) (networked from the IPC )
Cruise control deactivator switch (networked from the IPC )
Stoplamp switch (hard-wired)
The outputs of the PCM are:
Electronic Throttle Body (ETB) command
Cruise control Indicator (networked from the IPC )
The vehicle speed is controlled by the PCM through ETB . Cruise control electronics are contained
entirely within the PCM.
When the cruise control system is active, the PCM corrects for deviations in the actual vehicle speed by
proportionally moving the throttle plate. The PCM modulates the throttle to minimize error between the
actual vehicle speed and the desired speed.
The PCM strategy uses the throttle control for smooth accelerations.
The PCM sends a serial message over the HS-CAN to the IPC to command the cruise control indicator
to be turned on or off.
In the event of an off command or a deactivation request from the cruise control deactivator switch, the
cruise control system carries out a deactivation and immediately returns the throttle to the idle position.
The cruise control system provides self-diagnostics. The cruise control system disables operation and
sets a PCM or IPC DTC if it detects certain faults. The IPC does not indicate cruise control faults with an
indicator. Fault codes are logged by the PCM or IPC .
Additionally, the following conditions cause the cruise control system to deactivate:
Transmission gear selector in a position other than D or OD (automatic transaxle)
Clutch pedal is pressed (manual transaxle)
The cruise control set speed is overridden with the accelerator pedal for a period longer than 5
minutes
Vehicle speed loss from set speed of greater than 16 km/h (10 mph) occurs
Vehicle speed falls below the minimum allowable limit of 30 km/h (18 mph)
Cruise control switch pressed or stuck longer than 2 minutes

Normal Operation
The cruise control functionality is controlled through the cruise control switches that are hard-wired to the
Instrument Panel Cluster (IPC) through a signal and return circuit.
There are 5 cruise control switches with each switch operating a specific function that uses different
resistance values. The IPC sends out a reference voltage to the cruise control switches and monitors the
voltage drop when a cruise control switch is pressed. The voltage drop varies depending upon the
resistance of each switch, providing a specific indication to the IPC which switch is pressed. The IPC
sends a network message over the High Speed Controller Area Network (HS-CAN) to the PCM relaying
the switch status and requesting cruise control operation.
The stoplamp switch and cruise control deactivator switch signals are inputs to the PCM for the cruise
control operation.
When the brake pedal is applied, the normally open stoplamp switch closes and applies a voltage signal
to the PCM deactivating the cruise control, if engaged.
The cruise control deactivator switch is a normally closed switch that provides a ground signal to the
IPC . When the brake pedal is applied, the switch opens and removes the ground signal to the IPC . The
IPC sends a network message over the High Speed Controller Area Network (HS-CAN) to the PCM.
This is a redundant signal to the PCM.
The PCM receives both signals and compares the inputs to confirm that the correct brake input
sequence is received.
Vehicles equipped with a manual transaxle have an additional clutch pedal cruise control deactivator
switch. The clutch pedal cruise control deactivator switch is a normally open switch with the clutch pedal
not pressed. When the clutch pedal is applied, the clutch pedal cruise control deactivator switch moves
to the closed position, which routes the ground signal to the IPC . The IPC sends a network message
over the High Speed Controller Area Network (HS-CAN) to the PCM, deactivating the cruise control
system.
DTC P0704:01 (Clutch Switch Input Circuit: General Electrical Failure) — sets when the IPC
detects a short to ground in the clutch pedal cruise control deactivator switch signal during the

Pinpoint Test C: The Cruise Control Switches Do Not Operate Correctly
Refer to Wiring Diagrams Cell 31 , Cruise Control for schematic and connector information.
Normal Operation
There are 5 cruise control switches with each switch operating a specific function that uses different
resistance values. The Instrument Panel Cluster (IPC) sends out a reference voltage to the cruise
control switches and monitors the voltage drop when a cruise control switch is pressed. The voltage
drop varies depending upon the resistance of each switch, providing a specific indication to the IPC
which switch is pressed. The IPC sends a network message over the High Speed Controller Area
Network (HS-CAN) to the PCM activating and controlling the cruise control system.

Principles of Operation
The Body Control Module (BCM) controls various systems by monitoring inputs from switches, sensors
and messages sent over the Medium Speed Controller Area Network (MS-CAN) from other modules.
The BCM activates outputs based on the inputs received. For example, the BCM monitors the headlamp
switch position, and based on this input, the BCM may provide voltage to the exterior lamps.
Field-Effect Transistor (FET) Protection
A Field-Effect Transistor (FET) is a type of transistor that, when used with module software, monitors
and controls current flow on module outputs. The FET protection strategy prevents module damage in
the event of excessive current flow.
The BCM utilizes a FET protective circuit strategy for many of its outputs (such as a turn lamp output
circuit). Output loads (current level) are monitored for excessive current (typically short circuits) and are
shut down when a fault event is detected. A short circuit DTC sets when the fault event occurs.
The circuit remains off until the fault is corrected and the ignition state is cycled off and then back on, the
module resets the FET protection and allows the circuit to function.
Inspection and Verification
1. Verify the customer concern.
2. Visually inspect for obvious signs of electrical damage.
