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.

Module Configuration
Activation
1.
Install the most up-to-date software version in
the integrated diagnostic system (IDS).
2. In IDS, select the "Module reprogramming"
submenu in the "Module programming" menu
tool box and then follow the instructions.
3. Transfer a new software version (if available)
to the powertrain control module (PCM) using
IDS, if a module-reprogramming of the PCM
may be required in the case of engine running
concerns.
4. Following installation of a wheel/tire
combination, for which the tire-tread
circumference does not correspond to that of
standard tires, the tire size must be changed in
the PCM using IDS. Therefore select the
"Programmable parameters" submenu and enter
the corresponding tire size under the "tire size"
menu item. G1158256en

IDS.
6. If, before replacing a module, it was not possible
to read out the vehicle-specific data using the
integrated diagnostic system (IDS) (the module
to be replaced does not respond) then, during
programming of the new module, the
vehicle-specific data must be entered manually
via a selection list in IDS or via a code which
can be obtained from the Technical Hotline.
7. In order to program, select the "Install
programmable module" submenu in the "Module
programming" menu tool box and then follow
the instructions.
8. The following modules must be programmed
after replacement:
•
• Anti-lock braking system module (ABS)
• Audio system module (ACM)
• CD player (CDP)
• Driver's door control unit (D-DCU)
• Passenger's door control unit (P-DCU)
• Rear left door control unit (RL-DCU)
• Rear right door control unit (RR-DCU)
• Electrical power steering (EPS)
• Generic Display Module (GDM) (vehicles
with DVD navigation system with
touchscreen)
• Generic electronic module (GEM)
• Headlamp control module (HCM) (vehicles with gas discharge headlamps)
• Instrument cluster (IC)
• Navigation system (NAV) (vehicles with navigation system)
• Parking aid module(PAM)
• Powertrain control module (PCM)

9. In order to configure the PCM, select the
"Programmable parameters" submenu in the
"Module programming" menu tool box and then
follow the instructions.
10. For vehicles with anti-lock braking system and
electronic stability program, these must also be configured using IDS following replacement of
the lateral acceleration sensor, yaw rate sensor
or pressure sensor. Configuration is performed
in the "Programmable parameters" menu tool
box.

1. Verify the customer concern. 2. Check the electrical connectors for security,
damage and incorrect connection. If the
electrical connectors are broken, damaged or
incorrectly connected, repair or replace the
components as required. TEST the system for
normal operation before proceeding to the next
step. 3. Disconnect the electrical connectors and check
for the following:
• Moisture in the connector due to misaligned, damaged or missing seals.
• Contamination from leaking fluids in the region of the connector. • Damaged or oxidised connector pins.
•
Disengaged connector pins (this can be checked
by carefully pressing on the individual pins).
4. If any of the conditions listed are present, repair or replace the components as required. TEST
the system for normal operation before
proceeding to the next step. G1021921en
