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.

System Operation
GEM.
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
• Automatic headlamps
• Combined rain sensor/light sensor
• Windshield wash/wipe system
• Speed control – reads the speed control switches andtransmits signals on the CAN data bus
• central door locking – transmits signals on the CAN data bus
• 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

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.

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
