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

Module Controlled Functions – Overview
Generic electronics module (GEM)
CAUTIONS:
Never swap the GEM (generic electronic
module) between two vehicles.
Compare the number of relays and fuses
in the defective GEM and the new GEM.
Transfer from the defective GEM any relays
and fuses which are not in the new GEM.
In doing so, pay attention that fuses with
the correct Ampere rating are used, by
referring to the wiring diagrams.
NOTE: The GEM is integrated in the CJB (central
junction box) and cannot be replaced as a separate
unit.
For repair work during a service, vehicle-specific
configuration is necessary if a new GEM is
installed.
Emergency function
The GEM is equipped with restricted emergency
running functions on vehicles with mid or high-end
equipment levels.
The microcontroller sends a control signal to a
monitoring function within the GEM at regular
intervals. If the battery voltage falls below a value
of approx. 7.5 volts, this check signal is not present
and the GEM switches to emergency function after
a predetermined time.
In this case, the low beam is permanently switched
on, regardless of the light switch position. The
windshield wiper can only be operated in stage 1;
the wiper switch must however be in the stage I or
II position. The wiper park position is not
recognized. Intermittent wiping is not available.
When the control signal recurs, the GEM switches
back to normal operation.
Service mode
Description of operation
Diagnosis of the GEM can be carried out using the
Ford diagnostic unit. Furthermore, an integrated
service mode enables testing of the input and
output signals without the need for further tools.
To enable activation of service mode: • switch off the ignition,
• switch off all other electrical consumers,
• apply the handbrake,
• Shift to neutral
• and close the doors.
Activating the service mode
NOTE:
If the alarm is activated (in vehicles fitted
with an anti-theft alarm system), service mode
cannot be activated.
Proceed as follows to activate the service mode:
• OPERATE the switch of the heated rear window
and HOLD IT THERE
• SWITCH ON the ignition.
• RELEASE the switch of the heated rear window
A signal sounds and the turn signal lamps come
on to indicate that service mode has been
successfully activated.
Inputs
SWITCH the windshield wiper switch to the "OFF"
position to test the input signals. The following is
a list of the switch signals to be tested, in no
particular order:
• Windshield wiper stage I
• Windshield wiper stage II

Battery charging (Smart Charge)
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.
The alternator load is signaled to the PCM
(powertrain control module) in order to provide it
with an early indication when an electric component
is to be switched on or off, thereby also providing
information about imminent changes to the amount
of torque demanded by the alternator. By
evaluating this information the PCM is capable of
increasing the stability of the engine under idling.
The two remaining functions of the Smart Charge
system are controlled by the GEM. G1030788en

General overview
Haldex clutches of the 3rd and 4th generations are
used in the Ford Kuga.
The development of the third generation Haldex
clutch represents a big step forward in modern
all-wheel technology. The Haldex clutch is
electro-hydraulically controlled. Additional
information is taken into consideration during
control tasks via the all-wheel drive control unit.
Slip alone is no longer decisive for the distribution
of the propulsive forces; the vehicle's driving
dynamics are also taken into consideration. The
control unit accesses the driving-related data via
the data bus. With this data, the control unit has
all the essential information about speed, cornering,
coasting or traction operation, and can optimally
react to every driving situation.
Compared with the previous generation, the 4th
generation Haldex clutches operate with higher
pressure and achieve shorter response times when
distributing the drive forces.
Advantages of the Haldex clutch:
• Permanent all-wheel drive withelectronically-controlled multi-plate clutch
• Fast response
• No straining when parking and manoeuvring
• Compatible with different tyres (e.g. emergency spare wheel)
• Fully combinable with driving dynamic control systems
The driveshaft is connected to the input shaft of
the Haldex clutch. Within the Haldex clutch, the
input shaft is separated from the output shaft to
the rear axle differential by means of a multi-plate
clutch. Torque is only transmitted to the rear axle
differential when the plate assembly of the Haldex
clutch is closed.
The multi-plate clutch is electro-hydraulically
controlled via the all-wheel drive control unit. For
ecological driving, the torque to the rear axle is reduced to a minimum up to a throttle position of
approx. 50%. A prerequisite for this is that there is
no difference in speed in the Haldex clutch between
the input and output shafts.

and a working piston.
Fluid supply is started if there is a speed difference
between the input and output shafts.
This fluid pressure is transmitted to the working
piston and in this way the plate assembly is
compressed.

Brake System
General EquipmentPressure/vacuum gauge set
The Ford approved diagnostic tool
The brake system operates by transferring effort
applied to the brake pedal by the driver to the
brakes at each wheel.
The braking effort is distributed to each wheel,
using a hydraulic system. The system is assisted
using a vacuum brake booster that reduces pedal
effort and increases hydraulic pressure.
The parking brake operates on the rear wheels
and is applied using a hand operated control.
Inspection and Verification
NOTE: Before carrying out any diagnosis, make
sure that the brake system warning indicator is
functional.
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical or electrical damage.
Visual Inspection Chart
Electrical
Mechanical
• Electricalconnector(s)
• Wiring harness(s)
• Switch(es)
• Tire pressure(s)
• Wheels and tires
• Fluid leak(s)
3. If an obvious cause for an observed or reported concern is found, correct the case (if possible)
before proceeding to the next step.
4. If the cause if not visually evident, verify the symptom and refer to the Symptom Chart.
Road Test
Carry out a road test to compare actual vehicle
braking performance with the performance
standards expected by the driver. The ability of the
test driver to make valid comparisons and detect
performance deficiencies will depend on
experience.
The driver should have a thorough knowledge of
the brake system operation and accepted general performance guidelines to make good comparisons
and detect performance concerns.
An experienced technician will always establish a
route that will be used for all brake diagnosis road
tests. The road selected will be reasonably smooth
and level. Gravel or bumpy roads are not suitable
because the surface does not allow the tires to grip
the road equally. Crowned roads should be avoided
because of the large amount of weight shifted to
the low set of wheels on this type of road. Once
the route is established and consistently used, the
road surface variable can be eliminated from the
test results.
Before a road test, get a complete description of
the customer concerns or suspected condition.
From the description, the technician will be able to
match possible causes with symptoms. Certain
components will be identified as possible sources
while others will be eliminated by the evidence.
More importantly, the customer description can
reveal unsafe conditions which should be checked
or corrected before a road test. The description will
also help form the basic approach to the road test
by narrowing the concern to specific components,
vehicle speed or conditions.
Begin the road test with a general brake
performance check. Using the description of the
concern, test the brakes at different vehicle speeds
using both light and heavy pedal pressure.
Determine if the concern is in the front or rear
braking system. First use the foot brake and then
the parking brake. If the condition (i.e. pull,
vibration, pulsation) occurs only on operation of
the parking brake, the concern is in the rear brake
system. If the condition occurs when the foot brake
is depressed, the concern is in the front brake
system.
Avoid locking the brakes and sliding the tires. This
condition will not indicate brake efficiency. A heavily
braked but turning wheel will stop the vehicle in a
shorter distance than locked wheels.
If the concern becomes evident during this check,
make sure it fits the description given before the
road test. If the concern is not evident, attempt to
duplicate the condition using the information from
the description.
If a concern exists, use the Brake System Symptom
Chart in order to isolate it to a specific sub-system
and condition description. From this description, a
list of possible sources can be used to further
