Component Tests
Hydraulic Leak Check
NOTE: There is a common clutch and brake fluid
reservoir, therefore it is possible that a clutch leak
can lead to reduction in the reservoir level.
It is possible that all evidence of fluid leakage may
have washed off if the vehicle has been operated
in rain or snow, as brake fluid is water-soluble.
Refill the system, bleed then apply the brakes
several times. Examine the system to verify that
the reservoir fluid level is actually dropping. Locate
and repair the external leak. If the fluid level drops
and no external leak can be found, check for a
brake master cylinder bore end seal leak.
Brake System Check
Brake Pedal Reserve Check
Where a low brake pedal or the feel of a
bottomed-out condition exists, check for brake
pedal reserve.
1. Operate the engine at idle with the transaxle in the NEUTRAL position.
2. Apply the brake pedal lightly three or four times.
3. Allow 15 seconds for the vacuum to replenish the brake booster.
NOTE: This increased resistance may feel like
something has bottomed out.
4. Apply the brake pedal until it stops moving downward or an increased resistance to the
pedal travel occurs. 5. Hold the brake pedal in the applied position and
raise the engine speed to approximately 2000
rpm.
NOTE: The additional movement of the brake pedal
is the result of the increased engine manifold
vacuum which exerts more force on the brake
booster during engine rundown. This means that
additional stroke is available in the brake master
cylinder and the brake system is not bottoming out.
6. Release the accelerator pedal and observe that the brake pedal moves downward as the engine
returns to idle speed.
Brake Booster Functional Test
Inspect all hoses and connections. All unused
vacuum connectors should be capped. Hoses and
their connections should be correctly secured and
in good condition with no holes and no collapsed
areas. Inspect the check valve on the brake booster
for damage.
Brake Booster Operation Check
1. Check the hydraulic brake system for leaks orlow fluid.
2. With the transaxle in the NEUTRAL position, stop the engine and apply the parking brake.
Apply the brake pedal several times to exhaust
all the vacuum in the system.
3. With the engine turned off and the vacuum in the system exhausted, apply the brake pedal
and hold it down. Start the engine. If the vacuum
system is operating, the brake pedal will tend
to move downward under constant foot
pressure. If no motion is felt, the vacuum
booster system is not functioning.

FORD KUGA 2011.0MY WORKSHOP REPAIR MANUAL
HCU to check for sudden actuation of the brakes.
With the brake pedal pressed, the ABS module
triggers emergency braking if the rate of increase
of hydraulic pressure exceeds the predetermined
limit.
If the brake pedal is pressed so hard that the ABS
becomes active on the front wheels then the ABS
control unit increases the pressure to the rear
wheel brakes up to the ABS intervention threshold.
EBA operation continues until the driver releases
the brake pedal sufficiently for the hydraulic
pressure in the HCU to drop below a threshold
value stored in the ABS module.
Trailer stability control:If the vehicle is ordered
with a trailer coupling then the Trailer Stability
Control function is integrated in the ESP. The ESP
detects snaking when driving with a trailer and
reduces the speed of the vehicle and trailer through
adapted braking and, if necessary, by also reducing
the engine output until the snaking movement of
the trailer is corrected.
Roll-over protection: The ESP dynamically
determines the tipping tendency of the vehicle and
works in conjunction with the EBA system to
prevent the vehicle from tipping over during
dynamic maneuvers like lane changing or while
negotiating bends.
Emergency brake light: The emergency brake
light automatically switches on the hazard flasher
system to warn drivers of other vehicles that
emergency braking is being initiated. Based on a
defined delay value, the ABS/ESP module sends
a signal to the generic electronic module (GEM)
via the CAN data bus. The GEM activates the
hazard flasher system, that then flashes 7 times.
Prerequisites for activation of the emergency brake
light are:
• The speed is higher than 50 km/h.
• The brake pedal is being actuated.
• The deceleration is greater than 9 m/s².
To prevent activation on snow or ice, for example,
the following prerequisites must be met:
• The speed is higher than 50 km/h.
• The brake pedal is being actuated.
• ABS regulation takes place.
• The deceleration is greater than 6 m/s².
Tire pressure monitoring system: The tire
pressure monitoring system used in the Kuga is
able to detect loss of air in a tire at an early stage
and warn the driver. Because it can only compare
the behaviour of the tyres with each other, it is not possible to draw conclusions about the absolute
tyre pressure. It is also not possible to monitor the
spare tyre pressure. In order for the system to
operate correctly, the tyre pressures must be
regularly checked and corrected and the system
subsequently initialised (see below).
The tire pressure monitoring system used here,
depending on the equipment level, is built into the
anti-lock braking system (ABS) as an extra function
and therefore does not have its own sensors.
The ABS module measures the loss of pressure
in the tyres by calculation using the wheel speed
sensors of the ABS system. If a tyre loses
pressure, its diameter decreases and the speed of
the wheel therefore increases. If the ABS module
detects such a loss in pressure, it sends a signal
to the instrument cluster via the CAN bus and a
warning message is displayed in the message
centre. The warning threshold depends among
other things on the dimension of the tyres being
used, the vehicle operating conditions and the
status at the last initialisation. Since neither the
absolute tyre pressure nor the position of the tyre
is known, the pressure of all the tyres must be
checked and the system re-initialised after a tyre
pressure warning. If necessary, the cause of the
loss of pressure must be investigated.
Regular tyre pressure checks are still necessary.
The system must be initialised after a tyre is
changed, winter or summer tyres fitted, the
pressures corrected or adjusted to suit the vehicle
load. This can be done by the driver using the
driver information system. For further information,
see: Owner’s Manual.

generate a square wave output signal. The signal
acts in proportion to the rotational speed of the
sensor ring. The ABS sensor rings are built into
the seals in the front wheel bearings. The ABS
module evaluates the signals from all four sensors
to calculate a vehicle speed signal based on the
rotational speeds of all wheels. The road speed is
transmitted on the CAN bus. The powertrain controlmodule (PCM) uses this signal and the
programmed tire size to calculate the vehicle
speed. The calculated vehicle speed is forwarded
on the CAN bus and is requested by other control
units that need this input information.
