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:

FORD KUGA 2011.0MY WORKSHOP REPAIR MANUAL
• Starting process
• Engine running– Fuel supply to the engine including lambdacontrol
– Ignition setting including knock control
– Idle speed control
– Boost pressure control
– Valve timing via the camshaft adjuster for the intake and exhaust camshafts (including
internal exhaust gas recirculation)
• Refrigerant compressor (activation, deactivation and delivery)
• EVAP purge valve
• Charging system
Fuel is supplied to the engine via a sequential
multi-point injection system. Ignition is performed
by a distributor-less ignition system with one
ignition coil unit for each cylinder.
The PCM optimizes engine power and emissions
at all times by processing the sensor signals and
information received via the CAN databus and
using these for open or closed loop control of the
different variables.
The PCM contains part of the PATS (passive
anti-theft system).
The PCM is supplied with battery voltage via a fuse
in the BJB (battery junction box). This power supply
is needed to ensure that saved data is not lost
when the engine is switched off.
For other power supply requirements, the PCM
switches on a relay in the BJB which is responsible
for supplying power to the PCM and to some
sensors and actuators. Each of these are protected
by fuses in the BJB.
To guarantee optimum engine running at all times,
the PCM has several adaptive (self-learning)
functions. These adapt the output signals to
changing circumstances, such as wear or system
faults.
In some cases a faulty signal is replaced with a
substitute value or limited. A substitute value can
be calculated from other signals or it can be
predefined by the PCM. The substitute value allows
the vehicle to keep on running without the emission
values changing unduly. Depending on the signal
failure, the PCM operates in emergency mode. In
this mode, the engine power and/or the engine
speed is reduced to prevent further damage.
Depending on the faulty signal, a fault code is
stored in the error memory of the PCM. These can be read out using IDS (Integrated Diagnostic
System) via the DLC.
The PCM processes and evaluates the signals
from the sensors. The following sensors send
signals to the PCM:
• CMP sensors
• CKP sensor
• MAF sensor
•KS
• ECT sensor
• TP sensor
• APP sensor
• Broadband HO2S
• Catalyst monitor sensor
• MAPT sensor
• Air conditioning (A/C) pressure sensor
• Alternator
• Fuel temperature and fuel pressure sensor
• Engine oil level, temperature and quality sensor
• Outside air temperature sensor
The following components receive signals from the
PCM:
• Powertrain Control Module relay
• A/C clutch relay
• injectors
• Direct ignition coils
• Cooling fan module
• Throttle control unit
• Camshaft adjuster solenoid valve
• Starter Relay
• EVAP purge valve
• Alternator
• Heating element - broadband HO2S
• Catalyst monitor sensor heating element
• FPDM
• Wastegate control valve
• Air conditioning compressor
The PCM receives the following signals via the
CAN databus:
• APP
•CPP
• BPP
• Vehicle speed.
• Refrigerant compressor request
• PAT S

The APP sensor is a double contactless inductive
sensor. The APP sensor is integrated with the
accelerator pedal in the accelerator pedal module.
The inductive sensor essentially works in a similar
way to a transformer. The incoming DC voltage
first has to be converted into AC voltage.
Depressing the accelerator pedal moves a rotor.
This induces the AC voltage from the primary coil
into the secondary coil. The strength of the
induction depends on the position of the rotor:
• no accelerator-pedal actuation: low induction, i.e. low amplitude of the AC voltage,
• full accelerator-pedal actuation: high induction, i.e., high amplitude of the AC voltage.
To allow the PCM to process the AC voltage signal
output by the secondary coil, the signal must first
be converted into a PWM signal in the sensor
electronics.
In the APP sensor the signals are split as follows:
– APP 1 = PWM signal to the GEM and from there via the CAN data bus to the PCM.
– APP 2 = the analogue DC (direct current) signal is sent directly to the PCM.
Both signals are monitored by the PCM for
plausibility.
CPP sensor
E70695
The sensor works on the Hall-effect principle and
records the position of the piston in the master
cylinder without contact. The permanent magnet
required for recording the position is located in the
piston of the clutch master cylinder.
The signal from the CPP sensor is recorded by the
GEM and transmitted to the CAN via the PCM bus.
BPP switches
E94800
The BPP switch is designed as normally-closed
contact. In its rest state the switch is closed and
sends an earth signal to the GEM.
The brake light switch is designed as
normally-open contact and is open in its rest state.

Design:
• The gear ratios are achieved by means of acombined planetary gear set on the input side
and a Simpson set on the output side.
– The combined planetary gear set consists oftwo different, simple planetary gear sets. It
has a similar structure to a Ravigneaux set,
but with just one sun gear that engages with
the front planetary gears.
• Three multi-plate clutches
• Four multi-plate brakes • One band brake
• Two one-way clutches
The TCM adapts the gear changing to ensure that
the correct gear is selected for the style of driving,
the engine load, driver requirements, vehicle speed
etc.
The TCM features a self-learning strategy.
This leads to lower fuel consumption together with
improved comfort through smoother gear changes
and lower noise levels.

Depending on the input signals, the TCM mounted
on the transaxle actuates the solenoid valves
S1-S5 in the valve body. The solenoid valves are
either in the "open" or "closed" state.
The (SLT and SLS) control valves regulate the
hydraulic pressure according to the pulse/pause
ratio of the electrical PWM signal. The controlled
hydraulic pressure enables smooth shifting or the
generation of a defined slip through actuation of
the relevant clutches and brakes. The shift timing is calculated by the TCM using the
accelerator pedal position and vehicle speed.
Under normal conditions, gear shifting and torque
converter lockup occur at low engine speeds to
reduce fuel consumption.
If the accelerator pedal is pressed down quickly,
the TCM switches automatically into kickdown
mode.
