Strut or Shock Absorber Inspection
NOTE: Inspect the struts or shock absorber for
signs of oil weepage or leaks. Make sure that the
oil is not from another source.
Weepage:
• deposits a thin film of oil on the strut and spring assembly or shock absorber.
• is normally noticed due to a collection of dust on the strut and spring assembly or shock
absorber.
• occurs during the normal running-in period of 4800 - 8050 km. After this period no new signs
of oil should be visible.
• does not require new struts or shock absorbers to be installed.
Leakage:
• covers the entire strut and spring assembly or shock absorber with oil.
• will drip oil onto the surrounding suspension components.
• requires new struts or shock absorbers to be installed.
Strut or Shock Absorber Testing
NOTE: Struts or shock absorbers must be tested
in the vertical position.
1. Remove both strut and spring assemblies or shock absorbers. The piston rods should extend.
• Disassemble the strut and spring assemblies.
REFER to: Front Strut and Spring Assembly
(204-01 Front Suspension, Removal and
Installation).
2. Compress the piston rods. Both piston rods should offer the same resistance when
compressing.
3. Compress and release the piston rods. The piston rods should extent equally. 4. Compress and pull the piston rod in the vertical
position. Feel if the resistance force at the point
of direction change-over is perceptible without
a lag. If a lag is perceptible it is an indication of
damper valve damage and new struts or shock
absorbers must be installed. REFER to:
Front Strut and Spring Assembly (204-01 Front
Suspension, Removal and Installation),
Spring (204-02 Rear Suspension, Removal and
Installation).
Load-Levelling Shock Absorber
1. With the vehicle unladen, measure and note the dimensions between the base of the wheel rim
and the top of the rear fender on both sides.
• The measurements on both sides should be approximately equal.
2. With a load of 4 average size adults and a 100 kg weight, measure and note the dimensions
between the base of the wheel rim and the top
of the rear fender on both sides.
3. NOTE: Due to the internal ratchet mechanism of the suspension components, the height
of the rear of the vehicle should rise during
the road test.
With a load of 4 average size adults and a 100
kg weight, drive the vehicle for 3 km on a road
of normal condition.
4. With a load of 4 average size adults and a 100 kg weight, measure and note the dimensions
between the base of the wheel rim and the top
of the rear fender on both sides.
5. If the dimensions on both sides are no longer approximately equal, install new load levelling
shock absorbers.
REFER to: Spring(204-02 Rear Suspension,
Removal and Installation).
6. NOTE: Due to the internal ratchet mechanism of the suspension components, the height
of the rear of the vehicle should rise during
the road test.
If the dimensions are approximately equal,
unload the vehicle and drive the vehicle for 3
km on a road of normal condition.
7. With the vehicle unladen, measure and note the dimensions between the base of the wheel rim
and the top of the rear fender on both sides.
Check the final dimensions with the original

FORD KUGA 2011.0MY WORKSHOP REPAIR MANUAL

Tire Pressure Monitoring System (TPMS) – Overview
Description of operation
The tire pressure monitoring system is able to
detect loss of air in a tire at an early stage and warn
the driver. Because it can only compare the
behavior of the tires with each other, it is not
possible to draw conclusions about the absolute
tire pressure. It is also not possible to monitor the
spare tire pressure. In order for the system to
operate correctly, the tire pressures must be
regularly checked and corrected and the system
subsequently initialized (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 determines the loss of pressure
in the tires by calculation using the wheel speed
sensors of the ABS system. If a tire 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 driver information
system. The warning threshold depends among
other things on the dimension of the tires being
used, the vehicle operating conditions and the
status at the last initialization. Since neither the
absolute tire pressure nor the position of the tire is
known, after a tire pressure warning the pressure
of all the tires must be checked and the system
re-initialized. If necessary, the cause of the loss of
pressure must be investigated.
Furthermore, regular pressure checks are
necessary. The system must be initialized after a
tire is changed, winter or summer tires 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.

Engine Speed Sensitive
This means that the vibration occurs at varying
vehicle speeds when a different transmission gear
is selected. It can sometimes be isolated by
increasing or decreasing engine speed with the
transmission in NEUTRAL or by stall testing with
the transmission in gear. If the condition is engine
speed sensitive, the cause is probably not related
to the tires.
If the road test indicates that there is tire whine,
but no shake or vibration, the noise originates with
the contact between the tire and the road surface.A thumping noise usually means that the tire is flat
or has soft spots making a noise as they slap the
roadway. Tire whine can be distinguished from axle
noise. Tire whine remains the same over a range
of speeds.
A complete road test procedure is described in
Section 100-04.
REFER to:
Noise, Vibration and Harshness (NVH)
(100-04 Noise, Vibration and Harshness,
Diagnosis and Testing).

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.
