System Operation
Parking Aid WARNING: It is the driver's responsibility
to stay alert during reversing procedures.
The system may fail to detect small
children or animals.
CAUTION: The driver is responsible for
detecting obstacles and judging the
distance between these and the vehicle.
The system may fail to detect some
hanging objects, barriers, narrow obstacles
or painted surfaces, which could damage
the vehicle. Always pay attention when
parking.
The parking aid provides an audible warning to the
driver if there are any obstacles in front of or behind
the vehicle during reverse parking maneuvers.
At low speeds, the parking aid module uses the
parking aid sensors to monitor the area around the
vehicle. If an object is detected within a monitored
area, the parking aid module emits a warning tone
using the respective parking aid speaker.
The rear parking aid is switched on with the
ignition. However, it is only enabled when reverse
gear is selected.
The front and rear parking aid is always switched
off when the ignition is switched on. It is switched
on when reverse gear is selected or if the parking
aid switch in the center console is actuated up to
a speed of 16 km/h.
The parking aid is switched off when the vehicle is
travelling forwards at more than 16 km/h or if the
parking aid switch in the center console is actuated
again.
When the parking aid module activates the system,
the parking aid switch LED is illuminated. If the
vehicle is only fitted with the rear parking aid, there
is no switch.
The parking aid sensors emit a series of ultrasonic
impulses and switch to receiver mode to receive the echo reflected by an obstacle within the
detection range. The received echo signals are
amplified and converted from an analog signal to
a digital signal by the sensor. The digital signal is
passed to the parking aid module and compared
with pre-programmed data stored in an EEPROM
within the module. The module calculates the
distance to the obstacle by measuring the time
taken between the emitted and received impulses.
If no objects are detected there are no further
warning tones. If an object is detected, repeated
audible tones are emitted from either parking aid
speaker(s) as appropriate. The time delay between
the tones decreases as the distance between the
object and the vehicle decreases, until at
approximately 250 mm (10 inches), the audible
tone becomes continuous.
If the distance between the obstacle and the
vehicle does not decrease, the warning tone
remains constant if the object has been detected
by an internal parking aid sensor. If the obstacle
was detected by an external sensor and the
distance remains unchanged, the warning tone
stops after 3 seconds.
The parking aid module continues to monitor the
distance and will resume the warning tones if a
decrease in distance is detected.
If a trailer is connected to the vehicle, a signal is
sent to the GEM (generic electronic module) via
the trailer relay. This signal is sent to the parking
aid module via the MS CAN bus. When the parking
aid module detects that a trailer is connected to
the vehicle, the rear parking aid sensors are
disabled to prevent constant warnings due to the
close proximity of the trailer.

Component Description
Rear parking aid speaker
The rear parking aid speaker, in addition to its
actual function, is also used for audible indication
of various types of error in the front and rear
parking aids. If the rear parking aid speaker
becomes defective, the front parking aid speaker
will then be used to indicate failure modes.
If an error is detected in the system, a signal tone
is emitted via the speaker for 3 seconds.
Parking aid sensors
CAUTIONS:
Always keep sensors free from dirt, ice and
snow. Do not use any sharp objects to
clean the sensors.
If a high-pressure cleaner is used to wash
the vehicle, the jet must only be aimed at
the sensors briefly at a distance of at least
20 cm.
The parking aid sensor consists of the following:
• Plastic housing
• Aluminum membrane with Piezo disc
• Decoupling ring
• Printed circuit board (PCB)
The parking aid sensor consists of a sensor and a
holder. The holder makes sure that each parking
aid sensor is correctly orientated in relation to its
location in the rear bumper.
The sensors have a 3-pin connector which is
connected to the wiring harness of the front
bumper. This in turn is connected to the main body
wiring harness. Three pins provide for power
supply, ground and signal lines to and from the
parking aid module. The disc resonates at a frequency of ca. 50kHz,
producing the ultrasonic output. The disc also
receives the reflected echo signal from any objects
within range.
Parking aid module
The parking aid module has three connectors which
provide for power, ground and MS CAN bus
connections, as well as the front and rear parking
aid sensors, the parking aid switch and parking aid
speaker.
The parking aid module carries out self-check
routines and when the parking aid is active, checks
the parking aid sensor wiring for short or open
circuits. If a concern is detected, a diagnostic
trouble code (DTC) is stored in a memory in the
parking aid module and the front and rear parking
aid sensors will be disabled until the DTC is cleared
and the ignition cycled. The driver recognizes a
problem through the flashing LED and a shrill
continuous tone, which is emitted for 3 seconds
when the parking aid is activated. If the parking aid
is working properly, short tones are emitted instead
of this continuous tone. DTCs can be read using
the Ford approved diagnostic tool through the data
link connector (DLC).

Front parking aid speaker
The front parking aid speaker, in addition to its
actual function, is also used for audible indication
of various types of error in the front and rear
parking aids when the rear parking aid speaker
fails.
Parking aid switch
The parking aid switch is a non-locking switch with
an integrated LED for switching the parking aid on
and off. When pressed, the parking aid switch
momentarily connects a ground to the parking aid
module. The LED indicates when the parking aid
is active. The LED is controlled by the parking aid
module.
The parking aid switch allows the driver to disable
the parking aid when reverse gear is selected or
to activate the parking aid sensors when not in
reverse gear.
If a high tone is emitted for 3 seconds and the lights
in the switch flash, this indicates that there is a
fault. The system is then deactivated. Parking aid camera module
The data from the optional parking aid is sent to
the module via the Mid Speed CAN data bus. The
signals from the steering angle sensor are sent to
the module via cable. The module is connected to
the navigation device via a video-in/out cable.
Parking Aid Camera
The wide angle lens camera is fixed in the handle
strip of the tailgate. It is connected to the parking
aid camera module via a separate line.

Generator
General information
The powertrain control module (PCM) controls the
alternator charging voltage. The connection
between the PCM and the generator is made via
the control module subnetwork (LIN) bus.
If the load on the alternator is high, the PCM can
increase the idle speed.
The alternator is temporarily deactivated during
engine starting so that the engine drag moment is
minimized and it is reactivated again after the
starting procedure.
The PCM controls the charge control lamp in the
instrument cluster via the controller area network
(CAN) bus.
Smart Charge system
In addition to the familiar functions, the Smart
Charge system also performs the following
functions:
•
Automatic deactivation of non-critical high power
electrical consumers when the battery voltage
is low in order to reduce the level of current
drawn.
• Automatic activation of non-critical high power electrical consumers when the battery voltage
is excessively high in order to protect
components which are sensitive to increased
voltages.
The battery charging current is optimized through
continuous calculation of the battery temperature
and monitoring of the alternator output voltage.
By receiving the forwarded alternator load signal,
the PCM is given early warning whenever an
electric consumer is switched on or off. This means
that the PCM receives information about imminent
changes in the torque drawn by the alternator. By
evaluating this information the PCM can provide a
higher level of idling stability.
The two remaining functions of the Smart Charge
System are controlled by the GEM.
Electrical consumers are switched off due to low
voltage when the GEM determines (on the basis
of the message received from the PCM on the CAN
bus via the instrument cluster) that the battery
voltage has dropped below the threshold.
When the threshold for low battery voltage is
reached the GEM automatically deactivates the following consumers - in this order and with a gap
of 5 seconds between each:
• Electric booster heater (vehicles with diesel
engines)
• Heated exterior mirrors
• Heated rear window
• Heated windscreen
If the battery voltage rises back above the lower
threshold then the GEM re-enables all of the
electrical consumers which were previously
disabled. They then have switched off status and
must be switched back on by the driver.
Electrical consumers are switched on due to
excessively high voltage if the GEM determines
that the battery voltage is above the threshold for
overvoltage and the charge control lamp has been
switched on.
When the threshold is reached the GEM
automatically activates the following consumers -
in this order and with a gap of 5 seconds between
each:
• Heated rear window
• Heated exterior mirrors
• Electric booster heater (vehicles with diesel engines)
• Blower motor
If the battery voltage drops back below the
threshold then the GEM automatically deactivates
any consumers that were switched on. However,
if they were switched on by the driver before the
automatic activation, they will then be switched on
again in turn with a 5-second time interval. G964174en

Principles of Operation
NOTE: Voice control will only operate with the
audio unit and components required switched ON.
Voice Control
The portable support electronics (PSE) module
has a voice control system. The customer will be
able to push the VOICE button on the audio control
switch located on the steering column lower
shroud, this will activate the PSE module and allow
voice control. An audible tone will be heard through
the audio unit speakers after which, a voice
command can then be spoken into the microphone
located in the overhead console.
The incoming calls and voice confirmation can be
heard through the audio system speakers.
When a voice command is spoken into the
microphone it will be sent as a signal to the PSE
module. The signal is then sent from the PSE
module to the relevant components on the
medium-speed controller area network (CAN) bus
network. The component will then convert the
signal back into the original voice command.
The components that the PSE module interacts
with are as follows:
• audio unit
• navigation system display module
• cellular phone
For additional information on the cellular phone
system, REFER to the cellular phone Owner's
Guide.
Bluetooth
An input can be given through the cellular phone
with or without the cellular phone connected to the
handset holder. Providing that the cellular phone
is one of the recommended cellular phones for the
system, is supplied with the Bluetooth technology
and the cellular phone is programmed to the PSE
module.
When selected as active the Bluetooth technology
is a wireless system that interacts with the relevant component modules through the PSE module. The
general operation of the Bluetooth is similar to the
voice control.
Bluetooth technology cannot transfer the cellular
phone's PHONEBOOK or recent outgoing and
incoming call details to the audio unit or navigation
system display module. If the cellular phone is
placed into the handset holder the PHONEBOOK
data and recent outgoing and incoming call
information will be transferred to the audio unit or
navigation system display module.
For additional information, REFER to the cellular
phone Owner's Guide.
Inspection and Verification
NOTE: Make sure that the cellular phone is
featured on the list of recommended cellular
phones for the system.
Make sure that the PSE module and cellular
phone are configured to each other before
starting a system diagnosis. ENTER the
following PIN number on the cellular phone to
configure the cellular phone to the PSE module:
0000.
Make sure that the MUTE symbol is not
displayed on the audio unit when trying to
operate the cellular phone system. If the MUTE
symbol is displayed, this indicates that the PSE
module requires configuring to the vehicle and
the cellular phone requires programming to the
PSE module. GO to
Pinpoint Test C.
1. Verify the customer concern by operating the system using the customers cellular phone.
2. Visually inspect for obvious signs of electrical damage.

System Operation
In-car entertainment
The audio system is connected to the MS CAN
network and uses an internal amplifier which
directly drives the system speakers. It can only be
operated via the head unit and the radio remote
control. The head unit is connected to the vehicle
on the medium speed CAN bus. This allows the
unit to be interrogated for diagnostic purposes.
The automatic volume control (AVC) adjusts the
audio volume depending on the driving speed. The
audio device receives the necessary signals for
the ABS (anti-lock brake system) wheel sensors
from the instrument cluster on the MS-CAN. As
vehicle speed increases the audio level is adjusted
to compensate for extra road and vehicle noise.
Eight AVC settings are possible.
To choose the setting for automatic volume control,
press the MENU button until the AVC display
appears.
The required adjustment level is determined by the
Infotainment control unit based on the driving
speed signal. The vehicle speed signal is received
over the CAN. The signal is an average of the four
wheel speed sensor signals. Should an invalid
speed signal be received the AVC will not alter the
output volume.
AVC is controlled by the audio amplifier. Component Description
Vehicles with standard audio system
The standard audio system can only be used via
the head unit, the radio remote control and the
mobile electronic accessories module.

System Operation
Overview
NOTE: In order to prevent discharge of the battery,
if the vehicle is stationary, the Bluetooth mobile
phone and the voice control should only be used
for long periods when the engine is running.
NOTE: For certain mobile phones with the Symbian
operating system, a particular file must be installed
to allow full access to the telephone directory via
Bluetooth. This file is referred to as an SIS file and
can be downloaded from the Ford website. You
can obtain more detailed information from your
Ford dealer.
The system allows the driver to use a Bluetooth
equipped cellular phone handset through the
vehicles Information and Entertainment system.
A physical connection (adapter) between the phone
handset and the telephone control module is not
necessary and is therefore not available.
Communications between the two components are
purely Bluetooth. This can limit the available
functions dependant on the handset used.
The mobile phone system comprises the following
components:
• Control module for mobile electronic auxiliary equipment
• Microphone.
The control module for the mobile electronic
auxiliary equipment is connected to the
Infotainment system via the CAN bus and the audio
line. This enables audio and control signals to be
passed to and from the auxiliary equipment. The
mobile electronic auxiliary equipment control
module is equipped with a built-in Bluetooth
antenna.
Using Bluetooth it is possible to transfer audio files
from Bluetooth compatible storage media to the audio system and replay them (audio streaming).
This function will however only be available at a
later date.
Voice Control
Voice control makes it possible to operate the audio
system without the driver being distracted from the
traffic situation.
When the system is active, if the driver issues a
pre-defined order, the voice recognition system
converts this command into a control signal for the
various multimedia systems. The input can take
the form of dialogues or commands. The driver is
guided through the dialogues by announcements
or questions.
The following systems can be controlled using the
voice recognition system:
• Mobile phone
• Radio function
• CD player/CD changer
•
EATC (electronic automatic temperature control)
• DVD navigation system with touchscreen – Voice control via the mobile electronicauxiliary equipment control module is
unnecessary for the DVD navigation system
with touchscreen because this system has
its own integrated voice control function. G1055659en

The manual headlamp levelling system operates
with an electric motor which is controlled via a
rotary control in the instrument cluster.
Turn signals
The GEM switches the direction indicators and the
direction indicator side repeaters on.
The GEM sends a signal to the instrument cluster
via the CAN (controller area network) bus to switch
on the relevant turn indicator and the acoustic
signal.
The signals from the hazard flasher switch and
from the multifunction switch are transmitted to the
GEM via a wiring connection.
Combined rain sensor/light sensor
The ambient light sensor determines the general
light intensity.
For this purpose, it detects the light over as wide
an angle as possible, without taking the direction
of incidence into account.
The front light sensor determines the light intensity
directly in front of the vehicle.
If both the ambient light sensor and the front light
sensor detect a sudden reduction in light intensity
at the same time, then an algorithm-based
calculation is used to determine the fact that the
vehicle has entered a tunnel, a multi-storey car
park or a long underpass.
In this case the request for switching on the
external lighting and the indicator in the instrument
cluster is transmitted to the GEM.
If the vehicle enters into the shade thrown by a
large truck, the two sensors will register different
light intensities.. In this case, the algorithm-based
calculation will not result in the lights being
switched on.
The GEM incorporates a stepped switch-off of the
dipped beam headlamps, side lamps, license plate
illumination and the instrument cluster and
instrument panel illumination. If the ambient light
changes from dark to bright, the GEM first switches
off the low beams. The side lamps, license plate
lamps as well as the instrument cluster and
instrument panel illumination are switched off
approx. 6 seconds after the low beams have been
switched off.

System Operation
General
In a communications network (data bus system),
various modules of different systems are connected
to one another via one or several lines.
The data bus system is used exclusively for
transmitting data between the connected modules,
as well as between the connected modules and
the Ford diagnostic unit.
In a data bus system, complete data blocks are
transmitted instead of single on/off pulses. In
addition to the actual information, these data blocks
also contain data regarding the address of the
module to be addressed, the size of the data block
and information for monitoring the content of each
individual data block.
Data bus systems offer various advantages: • Simplified data transmission between the
modules due to a standardized protocol
• Fewer sensors and connectors
• Improved diagnostic options
• Lower costs
The DLC is connected to the various data bus
systems and to the power supply via the standard
16-pin GEM. The signal for the module
programming is also transferred via the DLC.
In a data bus system, if there is a break in one or
both lines or there is a short to ground or to voltage,
then communication between the modules and
with the Ford diagnostic unit is disturbed or is no
longer possible at all.
In order to be able to establish communication with
one another, the modules of the individual systems G1030779en

must use the same language. This language is
called a protocol.
At present, Ford uses three different data bus
systems. Depending upon model and equipment
level, all three data bus systems are used. Each
of these data bus systems has its own protocol.
Data bus systems
ISO 9141 bus
The International Organisation for Standardisation
ISO 9141 bus. This consists of a single wire and
is used exclusively for communication between the
modules and the Ford diagnostic unit. The fault
memories of the various modules are read out via
the ISO 9141 bus.
Local Interconnect Network (LIN) bus
The LIN bus is a standard specifically designed for
cost-effective communication between intelligent
sensors and actuators in vehicles. The LIN control
unit subnet is used in every situation where the
bandwidth and versatility of CAN is not needed.
The LIN specification comprises the LIN protocol,
a standard format for describing a complete LIN
and the interface between an LIN and the
application. An LIN comprises a LIN master and
one or more LIN slaves. The LIN utilizes the
master/slave principle for the purpose of bus
access control. This has the significant advantage
that few resources (CPU performance, ROM, RAM)
are required for bus management in the slave
module. The master is implemented in a control
module or a gateway which has the necessary
resources. All communication is initiated by the
master. Consequently, a message always consists
of a header, which is generated by the master, and
a response from the slave. The data transfer rate
is in the region of up to 20 Kbit/s. The LIN master
knows the time sequence of all data which are to
be transmitted. These data are transmitted by the
corresponding LIN slaves (e.g. ultrasonic sensors)
if they are requested to do so by the LIN master.
LIN is a single-wire bus, i.e. the data are
transmitted in the cable via one wire. Usually the
same cable is also used to provide the supply
voltage. The ground connection of the supply
voltage also acts as the ground connection of the
data transmission. An LIN does not use a
terminating resistor.
Controller Area Network (CAN) bus
This consists of two twisted wires and operates
serially (data is transmitted sequentially). It is used
for communication between the modules
themselves and between the modules and the Ford
diagnostic unit. The modules are connected to the
data bus in parallel. New modules can be
incorporated easily, without modifying the other
wiring or modules. The transmitted data is received
by every module connected to the control unit
network (CAN). As each data packet has an
identifier (label), in which the priority of the
message is determined as well as the content
identification, each module can detect whether or
not the data is relevant for its own information
processing. This enables several modules to be
addressed with a particular data packet and
supplied with data simultaneously. For this
purpose, it is ensured that important data (for
example from the ABS) is transmitted first. The
other modules are only able to submit their data to
the data bus after the high-priority messages have
been received.
The advantages of the CAN bus are:
• Minimization of wiring requirements
•
High degree of error protection (fault / fail-proof)
• Robustness
• Good extendibility
• Prioritization of messages
• Inexpensive
• Automatic repetition of faulty messages
• Independent system monitoring and the ability to disconnect faulty modules from the data bus
automatically
Due to the increased number of modules and the
resulting continued increase in data transfer, two
different CAN bus systems are used. Essentially,
they only differ in terms of their data transmission
rates and application areas.
To be able to distinguish between the individual
CAN bus systems, the CAN bus system with the
high transfer speed is called the high speed CAN
bus (HS-CAN). The data are transmitted at a baud
rate of 500 kB/s.
The CAN bus system with the medium transfer
speed is called the medium speed CAN bus
(MS-CAN) and is mainly used for communication
in the comfort electronics or the multimedia system.
The data are transmitted at a baud rate of 125 kB/s.
An interface (gateway) is used to exchange data
between the HS-CAN and the MS-CAN. This
provides the connection between the three CAN
databus systems and is installed in the GEM and
in the electronic instrument cluster. The number of
modules which are connected to the three databus G1030779en
