The GEM switches the direction indicators and the
direction indicator side repeaters on.
The GEM sends a signal to the instrument cluster
via the CAN bus to switch on the relevant turn
indicator and the acoustic signal.
The signals from the hazard flasher switch and
from the multifunction switch are transmitted to the
GEM via a wiring connection.
The turn signals and the warning lamp flash at a
specified frequency and, in the case of failure of a
turn signal, the frequency is doubled.
The turn signal lamps also have a one-touch lane
change function. If the multifunction lever is
pressed just slightly then the relevant turn signal
lamp is actuated 3 times by the GEM.
Interior lighting
Depending on the vehicle specification, the interior
lighting includes:
• Left and right-hand footwell lamps
• Overhead lights at front and rear
Depending on the vehicle specification, the
switchable interior lighting includes:
• Map lights
• Mirror lights in sun visors
• Glove compartment lamp
• Luggage compartment lamp
The front and rear overhead lights are switched on
by the GEM. The interior lighting is switched on if one of the
following conditions is satisfied:
One of the vehicle's doors is opened.
The ignition key is in the "0" or "I" position and the
vehicle is unlocked.
The ignition key is turned from the "II" to the "I" or
"0" position.
The interior lighting is switched off when all of the
doors are closed and one of the following
conditions is satisfied:
• 25 seconds have elapsed since the last door
was closed.
• The ignition key is turned from the "0" or "I" to the "II" position.

4. Remove the vacuum hose from the brakebooster. Manifold vacuum should be available
at the brake booster end of the hose with the
engine at idle speed and the transaxle in the
NEUTRAL position. Make sure that all unused
vacuum outlets are correctly capped, hose
connectors are correctly secured and vacuum
hoses are in good condition. When it is
established that manifold vacuum is available
to the brake booster, connect the vacuum hose
to the brake booster and repeat Step 3. If no
downward movement of the brake pedal is felt,
install a new brake booster.
5. Operate the engine a minimum of 10 seconds at approximately 1200 rpm. Stop the engine and
let the vehicle stand for 10 minutes. Then, apply
the brake pedal with approximately 89 N (20 lb)
force. The pedal feel (brake application) should
be the same as that noted with the engine
operating. If the brake pedal feels hard (no
power assist), install a new vacuum check valve
and then repeat the test. If the brake pedal still
feels hard, install a new brake booster. If the
brake pedal movement feels spongy, bleed the
brake system. REFER to: (206-00 Brake System
- General Information)
Brake System Bleeding (General Procedures),
Brake System Pressure Bleeding (General
Procedures),
Component Bleeding (General Procedures).
Brake Master Cylinder
Usually, the first and strongest indicator of anything
wrong with the braking system is a feeling through
the brake pedal. In diagnosing the condition of the
brake master cylinder, check pedal feel as
evidence of a brake concern. Check for the red
brake warning indicator illumination and the fluid
level in the master cylinder reservoir.
Normal Conditions
The following conditions are considered normal
and are not indications that the brake master
cylinder is in need of service.
– Modern brake systems are not designed to
produce as hard a pedal effort as in the past.
Complaints of light pedal efforts should be compared to pedal efforts of another vehicle, of
the same model and year.
– During normal operation of the brake pedal, the fluid level in the reservoir will rise during brake
pedal application and fall during release. The
net fluid level (i.e., after brake pedal application
and release) will remain unchanged.
– A trace of brake fluid will exists on the brake booster shell below the master cylinder
mounting flange. This results from the normal
lubricating action of the master cylinder bore
end seal.
– The fluid level will fall with brake shoe and lining wear.
Abnormal Conditions
NOTE: Prior to performing any diagnosis, make
sure the brake system warning indicator is
functional.
Changes in brake pedal feel or travel are indicators
that something could be wrong with the braking
system. The diagnostic procedure and techniques
use brake pedal feel, warning indicator illumination
and low brake fluid level as indicators in diagnosing
braking system concerns. The following conditions
are considered abnormal and indicate that the
brake master cylinder is in need of service.
– The brake pedal goes down fast. This could be caused by an external or internal leak.
– The brake pedal eases down slowly. This could be caused by an external or internal leak.
– The brake pedal is low and or feels spongy. This condition may be caused by no fluid in the brake
master cylinder reservoir, reservoir cap vent
holes clogged or air in the hydraulic system.
– The brake pedal effort is excessive. This may be caused by a bind or obstruction in the pedal
or linkage, clogged fluid control valve or
insufficient booster vacuum.
– The rear brakes lock up during light pedal force. This may be caused by incorrect tire pressures,
grease or fluid on the brake shoes and linings,
damaged brake shoes and linings, incorrectly
adjusted parking brake, or damaged or
contaminated brake pressure control valves.
– The brake pedal effort is erratic. This condition could be caused by a brake booster malfunction,
extreme caliper piston knock back or incorrectly
installed brake shoes and linings.
– The red brake warning indicator is ON. This may be caused by low fluid level, ignition wire routing

a diagnostic tester.
The following components can be replaced
separately or as a unit:
• Hydraulic Control Unit (HCU)
• ABS/ESP module
• Mounting Bracket
The following must be taken into account when
removing/installing or renewing the ABS/ESP
module or the hydraulic control unit (HCU):
• Only hydraulic control units (HCU) which are pre-filled with brake fluid are available for
service operations.
• After replacing the HCU it is not necessary to bleed the system via the diagnostic tester.
• After replacing the brake fluid it is also only necessary to perform standard bleeding.
• The blanking caps/plugs must not be removed until the brake tubes are ready to be connected. • If accidentally dropped or knocked install a new
hydraulic control unit (HCU) and module
assembly.
• When the ABS/ESP module is removed/installed or replaced, it is necessary to reconfigure the
ABS/ESP module with the aid of the diagnostic
tester once all of the installation work has been
performed.

FORD KUGA 2011.0MY WORKSHOP REPAIR MANUAL

ESP switch
E99006
Stability assist can be deactivated via the menu in
the instrument cluster. The stability assist functions
are deactivated when the Set switch is actuated.
The ABS control module makes the stability assist
functions available once more when the Set switch
is actuated again. The stability assist function is
automatically reactivated when the ignition is
switched on.
The electronic EBA is a constant function and will
remain active even if the ESP has been switched
off.
Combined yaw rate sensor and lateral
acceleration sensor / longitudinal
acceleration sensor
E96822
The heart of the combined yaw rate sensor and
lateral acceleration sensor/longitudinal acceleration
sensor is a small, double-sided tuning fork made
of a piezo crystal (A). The exciter side of this tuning
fork is set to a resonance of 11 kHz with the aid of
an alternating current. The measuring side of the
tuning fork features a resonance frequency of 11.33
kHz and therefore does not vibrate (B). Since,
under influence of an external accelerating force,
a vibrating mass reacts slower than a comparable
mass that is not vibrating, the tuning fork twists
within itself with rotational movement being
imparted on the sensor (C). This rotation results
in a change in the charge distribution in the Piezo
element, which is subsequently picked up and
converted into an electronic signal by electronics
integrated into the sensor. This electronic signal is
then sent to the ESP module. The ESP module
evaluates these data and takes into account the
other input data (vehicle speed, wheel speed)
before deciding whether the ESP function is
required.
