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 following functions are controlled or performed
by the GEM at a battery voltage of between 9 and
16 volts:
• Current distribution
• Battery charging (Smart Charge)
• Ignition overload protection
• Headlamp switch-off delay
• Turn signals
• Interior lighting
• Heated windscreen
• Heated rear window and heated external mirrors
• Ambient air temperature
• Brake fluid level

• Anti-theft
• Electric booster Heater
• Climate control
• Parking brake –(monitors the switch and transmits the signal
on the CAN data bus
• Communication via the medium-speed CAN data bus Component Description
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

Electrical consumers are switched off when the
battery voltage is low if the GEM determines (as a
result of the message received from the PCM on
the CAN bus via the instrument cluster) that the
battery voltage has dropped below the threshold
value.
When the threshold for low battery voltage is
reached the GEM switches off the following
consumers in this order at intervals of 5 seconds:
• Heated windscreen
• Heated rear window
• Electric booster Heater
• A/C system
If the battery voltage increases back above the
lower threshold then all of the consumers which
were previously switched off are reactivated by the
GEM.
Once the electric consumers have been reactivated
their status is "switched off", i.e. the consumers
are switched off and await an input signal provided
from the relevant switch via the GEM; this means
that the driver needs to switch these components
back on again.
Electrical consumers are switched on when the
battery voltage is excessively high if the GEM
determines that the battery voltage has increased
above the threshold for overvoltage and the
charging system warning indicator has come on.
When the threshold is reached the GEM switches
on the following consumers in this order at intervals
of 5 seconds:
• Heated windscreen
• Heated rear window
When these components are deactivated again
their status is "switched off". This means that the
consumers are waiting for an input signal provided
from the relevant switch via the GEM.
Ignition overload protection
The ignition overload protection intermittently
disconnects certain circuits in order to restrict the
current being drawn from the battery while the
starter motor is operating.
The position of the ignition switch is broadcast by
the instrument cluster on the medium speed CAN
bus.
The ignition overload protection relay which is
integrated in the battery junction box is activated
by the GEM if the message "ignition switch in
position III" is received from the instrument cluster.
All of the electric consumers controlled by the
ignition overload protection relay are then switched
off.
The following consumers (among others) are
controlled by the ignition overload protection relay:
• Fog lamps
• Windscreen/rear window wash/wipe systems
• Backup lamps
• Heated washer nozzles
• Heating blower motor
• Seat heating
Headlamp switch-off delay
The headlamp switch-off delay utilizes the low
beam together with the peripheral lights (if
equipped) to illuminate the area surrounding the
vehicle. The function is activated by operating the
high beam lever when the ignition switch is in the
"0" position.
After the last door has been closed, the function
remains active for a further 30 seconds and then
switches off automatically.
When a door or the tailgate is open, the switch-off
time is extended to 180 seconds. After the last door
has been closed, the switch-off time is reset to 30
seconds.
The headlamp switch-off delay can be deactivated
prematurely by operating the high beam lever again
or by switching on the ignition.
The switch-off time is adjusted to set values at the
factory and cannot be re-programmed using the
Ford diagnostic unit.

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.

The ABS monitors the different wheel speeds of
the vehicle with the aid of wheel speed sensors.
Using the data from all of the wheel speed sensors,
the ABS module calculates the so-called reference
speed, which is a measure of the actual road
speed. The ABS module compares the individual
circumferential wheel speeds with this reference
speed when the driver initiates braking. If one or
more of the circumferential wheel speeds deviates
too far from the reference speed, this means that
slip at the affected wheels is so great that steering
stability of the vehicle is no longer ensured. The
ABS module actuates electro-mechanical valves
which influence the brake pressure at the relevant
wheels.
Like the traction control system (TCS), the ESP
system uses a large proportion of the ABS
components. In addition, there are sensors which
pick up the steering angle, the acceleration forces
acting on the vehicle and the yaw rate or yaw
moment. The sensors transmit these signals to the
combined ABS/ESP module. Using the wheel
speed and steering angle data, the ABS/ESP
module calculates the direction of travel planned
by the driver and determines the corresponding
speed-dependent lateral acceleration and yaw
moment. These values are compared with those
actual measured. If the actual lateral acceleration
and the yaw moment deviate excessively from the
target values (unstable driving characteristics), the
ABS/ESP module actuates individual brakes
selectively via the HCU (hydraulic control unit). In
addition, the engine speed is reduced by
intervention in the engine management system.
How the system works for understeer: In the
event of understeer, brake intervention occurs at
the wheels on the inside of the curve. The rear
wheel is braked heavily, so that a high amount of slip is caused. In this way, the cornering force of
the rear axle is heavily reduced and the centrifugal
force that now becomes effective turns the rear of
the vehicle back into the curve. The front wheel is
not braked as hard. The braking force that is
transmitted via the front wheel to the road surface
generates a torque with the aid of the lever arm
(vertical tire force to the vehicle's centre of gravity),
which supports the yaw moment of the vehicle.
Both measures together result in the vehicle
reverting back to the curved path intended by the
driver.
How the system works for oversteer:
In the
event of oversteer the wheels on the outside of the
curve are braked. This time, the front wheel is
subjected to a high level of slip so that the
cornering force at the front axle is reduced. The
rear wheel is not braked as heavily and, together
with the effective lever arm, results in a reduction
in the vehicle yaw moment. Both measures
together result in the vehicle being stabilized and
reverting back to the curved path intended by the
driver.
If ESP control occurs, possible ABS interventions
will be overridden as the ESP works at higher slip
rates than the ABS.
Emergency brake assist (EBA): The emergency
brake assist helps drivers in emergency braking
situations by automatically applying the brakes with
the maximum possible braking force.
If the brake pedal is pressed very suddenly, the
ABS module increases the hydraulic pressure to
all of the brakes until the threshold for ABS
intervention is reached. This applies the maximum
braking effort for the available traction. The ABS
control unit monitors inputs from the brake pedal
switch and from the pressure sensor within the

generate a square wave output signal. The signal
acts in proportion to the rotational speed of the
sensor ring. The ABS sensor rings are built into
the seals in the front wheel bearings. The ABS
module evaluates the signals from all four sensors
to calculate a vehicle speed signal based on the
rotational speeds of all wheels. The road speed is
transmitted on the CAN bus. The powertrain controlmodule (PCM) uses this signal and the
programmed tire size to calculate the vehicle
speed. The calculated vehicle speed is forwarded
on the CAN bus and is requested by other control
units that need this input information.

System Operation
Electronic principle of operation
The power steering module requires the following
information in order to ensure precise steering
behavior in all driving situations:
• Steering wheel position
• Rate of turn of the steering wheel
• Vehicle speed
• Information about the vehicle configuration
• Information about the ignition switch position
• Instantaneous engine operating status
The required information is made available to the
power steering module via direct connections and
via the CAN bus (refer to the flow chart).
The steering wheel position and the rate of turn of
the steering wheel are transmitted to the power
steering module as PWM signals from the steering
angle sensor. The steering angle sensor receives
its voltage and ground supply from the power
steering module and operates inductively with an
input voltage of 5 V.
The vehicle speed is made available to the power
steering module as a CAN bus signal from the ABS
module or ESP module. The engine operating status is made available to
the power steering module as a CAN bus signal
from the PCM.
The power steering module obtains the vehicle
configuration information via the CAN bus from the
GEM. This information is required by the power
steering module in order to define the internal
characteristics of the power steering.
The power steering module obtains information
about the current ignition switch position via the
voltage input (terminal 15) of the ignition switch.
Whilst constantly monitoring the relevant input
signals the power steering module accesses stored
maps. With the aid of this information the pump
speed is matched to the current driving situation.
An electronic diagnosis of the electro-hydraulic
power steering can be performed with the aid of a
diagnostic tester via the DLC of the vehicle. For
additional information please refer to "Diagnosis
and Testing" in this section.
