2011 FORD KUGA junction box

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

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.

Output signals
SWITCH the wiper switch to the "intermittent""
position to test the output signals. PRESSING the
heated rear window switch activates the output
signals in the following order:
a.
Left-hand turn signal
b. Right-hand turn signal
c. Main beam
d. Dipped beam
e. Windshield wiper stage I
f. Windshield wiper stage II
g. Heated rear windshield
h. Heater blower motor
i. Headlamp washer system (vehicles with HID headlamps)
j. Electric booster heater (if fitted)
k. Autolamps (position lamps only if fitted)
l. Alarm horn (vehicles with alarm system)
m. Rear window wiper
n. Heated front window relay
When the heated rear window switch is pressed
again, the test of the relevant signal is terminated.
When the heated rear window switch is pressed
once more, the test for the next signal in the list is
started.
End service mode
The GEM automatically ends service mode 20
seconds after the last input or at a driving speed
of over 7km/h. However, service mode can be
manually ended at any time by proceeding as
follows:
• PRESS and HOLD the switch of the heated rear
window
• SWITCH OFF the ignition.
• RELEASE the switch of the heated rear window
3 signals sound and the turn signal lamps illuminate
to indicate that service mode has ended.
Reset service mode
If, after completion of service mode, some functions
do not operate or do not operate properly, check
the following functions:
• Instrument cluster illumination, side marker lamps (side lights) and licence plate lamp in
automatic headlamps mode
• Rear wiper
• Headlamp washer assembly
• Electric booster heater • Alarm horn
• Heated windshield
If one or more of the listed functions is not OK, it's
possible that the cause of the fault is due to not
exiting service mode properly. To reactivate the
functions correctly, perform the following steps:
1. Switch off the ignition.
2. SWITCH OFF the switch for the windscreen
wash/wipe system
3. OPERATE the switch of the heated rear window
and HOLD IT THERE
4. SWITCH ON the ignition.
5. RELEASE the heated rear window switch (an acoustic signal will sound if activation has been
performed correctly)
6. SWITCH the windscreen wash/wipe switch to the "Intermittent wipe" position
7. OPERATE the heated rear window switch 6 times (the main beam headlamps switch on and
off automatically)
8. SWITCH OFF the switch for the windscreen wash/wipe system
9. OPERATE the switch of the heated rear window
and HOLD IT THERE
10. Switch off the ignition.
11. RELEASE the heated rear window switch (three
acoustic signals will sound if activation has been
performed correctly)
After completion of the work, check all the
functions.

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

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.
