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.

FORD KUGA 2011.0MY WORKSHOP REPAIR MANUAL

Powertrain Control Module (PCM)
E65160
The PCM communicates with all engine sensors
and the other modules. Communication of the PCM
with the other modules and the system diagnostics
takes place via the CAN (controller area network)
data bus.
The following functions are regulated or controlled
by the PCM:
• Fuel supply to the engine including lambdacontrol
• Ignition setting including knock control
• Idle speed control
• Control of optimum valve timing via the camshaft adjustment for intake and exhaust camshafts
• The refrigerant compressor is controlled by the air conditioning clutch relay and the delivery of
the refrigerant compressor is controlled by a
PWM (pulse width modulation) signal.
• Control of EVAP purge valve
• Boost pressure control
• Control of the cooling fan
• Charging system (Smart Charge)
• Starting system (Smart Start)
If the PCM is isolated from the vehicle electrical
system or the battery is disconnected, the throttle
control unit mustbe initialized.
The PCM is fitted in the engine compartment in the
air filter housing. On right hand drive vehicles a
protective metal plate is also installed to prevent
the plug connector from being pulled off, or make
it harder to pull off, in case of theft. The protective
plate is secured with a shear bolt. The shear bolt
needs to be drilled out in order to remove the
protective plate.
Knock Sensor
E96986
Two KSs are fitted. They are on the cylinder block,
one close to the 2nd cylinder and one close to the
4th cylinder.
When fitting, adhere strictly to the specified
tightening torque, otherwise the KS will not work
properly.
If the signal from one or both KS is implausible or
absent, knock control is deactivated. The PCM
switches to an ignition map that is further away
from the knock limit. As a result, engine damage
caused by combustion knock is avoided. If a fault
occurs, a fault code is stored in the error memory
of the PCM.
Camshaft Position (CMP) Sensor
E89993
If one or both CMP sensors fail, a fault is saved in
the error memory of the PCM and the camshaft
adjustment and knock control are deactivated.

System Operation
The engine is controlled by the PCM. For this
purpose, the PCM uses information from the
sensors, sender units and switches. In addition,
the PCM receives information from other control
modules via the CAN data bus. All the information
is processed in the PCM and is used to control or
regulate the different actuators.
These are:
• the throttle control unit,
• the fuel injectors, • the camshaft adjustment,
• the boost control solenoid valve
• and the ignition coils.
Some values are sent via the CAN databus to other
systems.
The following functions are regulated or controlled
by the PCM:
