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
• Windshield washer system
• Rear window wiper
• Rear window washer system
• Doors open/closed
• Remote control for central locking with double locking
• Hood open/closed (in vehicles equipped with an anti-theft alarm system)
• Tailgate open/closed
• A/C request signal
• Heated windscreen (if fitted)

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

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.
