Communications Network – Overview
In order to minimize module variations, different
equipment levels and functionalities are
incorporated in the same module. For this reason,
modules must be programmed following
replacement. For this purpose, the vehicle-specific
data are read out of the module to be replaced
using "Install programmable modules" routine in
the Ford diagnostic unit and transferred to the new
module. In the process, it is also possible to replace
older software versions with more up-to-date
versions, for example.
If it was not possible to read out any
vehicle-specific data with the Ford diagnostic unit
before replacing a module (the module to be
replaced does not respond), the data available in
the OASIS system (ASBUILT data) must be
entered manually using the Ford diagnostic unit
when programming the module.

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

systems depends on the equipment level of the
vehicle.
In order to guarantee a high degree of error
protection, two 120 Ohm terminating resistors are
installed in the CAN. These are integrated in the
first module connected to the CAN and in the last
module connected to the CAN respectively and
are used for suppression as well as the elimination
of voltage peaks. In order to ensure correct
functioning of the data bus system, the modules
must always be connected with an integral
terminating resistor. In order to enable
communication between the modules on the
HS-CAN and the modules on the MS-CAN, one
module is connected to both data bus systems.
The connection of both data bus systems is
designated as a gateway. In this gateway, the
received data is converted to the transmission rate
required for the relevant data bus and is
transmitted. This ensures an optimal distribution
of information between both data bus systems.

The GEM is integrated in the CJB (central junction
box) and cannot be replaced as a separate unit.

System Operation
Anti-theft warning system
Three anti-theft alarm systems are available,
depending on the market and model version:
• The system with perimeter monitoring detects whenever the doors, the hood, the folding rear
window and the liftgate are opened.
• The system with perimeter and interior monitoring in addition detects unauthorised
access, for example, through a broken window.
• A Thatcham category I anti-theft alarm system (mainly for the British market) is fitted with a
horn that has its own battery power supply; it
also uses slightly different detection strategies.
The anti-theft alarm system outputs an acoustic
and visual signal if unauthorised persons attempt
to gain access to the vehicle.
As a visual warning, the system switches on the
hazard warning lights, whilst the acoustic warning
is done with the anti-theft alarm system horn or the
horn with its own battery power supply.
When the ignition is switched off, the anti-theft
alarm system is activated 20 seconds after any
latch is activated, i.e. the hood, all doors, the
folding rear window and the liftgate are alarmed,
provided that they are fully closed. If the hood, one of the doors, the folding rear
window or the liftgate is not completely closed, it
can be opened without the alarm being triggered
since the system was not activated.
The anti-theft alarm system can be switched off by
unlocking the vehicle either via the remote controls
or the door lock.
NOTE:
To switch off the alarm on a Thatcham
category I anti-theft alarm system, the ignition must
be switched on within 12 seconds of the door being
unlocked with the key.
If the folding rear window or the liftgate is opened
via the remote control, the anti-theft alarm system
blocks the trigger for the alarm system or the
interior monitoring (if fitted) for 20 seconds after
closing.
NOTE: If a window is not fully closed, there is a
risk that a false alarm will be triggered. G1065780en

System Operation
Passive Anti-theft System
The passive anti-theft system PATS (passive
anti-theft system) is based on an electronic engine
immobiliser.
The driver does not need to intervene in any way
to protect the vehicle, since PATS is automatically
activated when the ignition is switched off.
Component Description
Keyless vehicle module (KVM) The PATS functionality is saved in the KVM. After
pressing the start/stop button, the KVM activates
the interior antennas, which then transmit a signal.
If there is a valid passive key in the vehicle interior,
it sends an encrypted signal to the radio frequency
receiver. The radio receiver forwards this signal to
the KVM via a fixed wire. The KVM then forwards
a corresponding identification query via the HS
CAN (controller area network) to the PCM.
If a valid code was received to this query, then the
engine can be started. Interior antennas
The four interior antennas transmit an LF signal
which is identified by the passive key.

The all-wheel drive control unit is bolted directly to
the housing of the Haldex clutch.
It forms one unit made up of the control valve, a
pressure/temperature sensor, and a control
module. It receives signals from the PCM and from
the ABS control module via the CAN data bus. The
control module in the control unit uses these
signals to determine the fluid pressure that is
needed to actuate the clutch plates depending on
the requirement. This determines how much torque
should be transmitted to the rear wheels. All-wheel
drive is deactivated if a fault occurs in the all-wheel
drive control unit.
A preload of approx. 80 Nm is always present at
the Haldex clutch. The temperature sensor of the Haldex clutch is
installed near the control valve in the control unit
and is surrounded by the hydraulic fluid. The
temperature is transmitted to the control module
and is used for adaptation to the changing viscosity
of the hydraulic fluid. If the hydraulic fluid is cold,
the control valve has to be opened slightly more
than requested. This allowance has to be reduced
as the temperature increases. The normal working
temperature of the hydraulic fluid is between +40
°C and +60 °C. If the temperature rises above 100
°C, the clutch is depressurised; if the temperature
falls below 95 °C, the clutch is pressurised again.
All-wheel drive is deactivated and a diagnostic
trouble code set if a fault occurs in the temperature
sensor.
With Haldex Generations I and II, the control valve
was actuated via a stepper motor. With Haldex
Generation III, the stepper motor has been omitted.
The control valve is now actuated via a solenoid
valve. The solenoid valve is actuated by the control
module in the all-wheel drive control unit by means
of pulse width modulation. The pulse width
modulation determines the position of the
adjustment spindle and thus the opening cross
section of the return hole. This is how the pressure
at the working piston of the plates is determined.
If the return hole is fully closed, maximum pressure
is applied to the plates. If the return hole is fully
open, the plates are unpressurized.
Electric feed pump
The electric feed pump is installed in the clutch
unit. It works according to the gerotor principle.
The main purpose of the feed pump is to fill the
pressure accumulator and the space behind the
pump plunger with hydraulic fluid, thereby ensuring
a fast response time of the Haldex clutch. The feed
pump used in the third generation is designed to
achieve an even higher pressure than the base
pressure of 4 bar. It is supplied with current by the
control module in the all-wheel drive control unit
when the engine is running above approx. 400 rpm.
