2011 FORD KUGA ECO mode

control saves the current speed as the target
speed.
Cruise control goes into STANDBY mode in the
following situations:
• Operation of the brake pedal
• Operation of the clutch pedal
• Operation of the parking brake
• If the driver operates the accelerator pedal andthe saved target speed is subsequently
exceeded for more than 5 minutes.
• Pressing any cruise control button for more than 2 minutes
• Intervention by the traction control or electronic stability program (for longer than 40 ms)
• Shifting of the gear selector lever to the "N" position (vehicles with automatic transmission
only)
• Minimum speed falls below 40 km/h.
• Occurrence of particular DTC (diagnostic trouble code)
• faulty signal from the backup lamp switch
Cruise control is switched off when the "OFF"
button is pressed.
If the accelerator pedal is pressed down, the
vehicle speed increases. As soon as the pedal is
released, the speed falls to the saved target value. The following components supply the signals
needed by the cruise control:
• The APP sensor.
– The APP sensor identifies the currentposition of the accelerator pedal and sends
a PWM (pulse width modulation) signal to
the PCM and an analog DC (direct current)
signal to the GEM.
– If one or both of the APP sensors fails, a fault is stored in the PCM fault memory and cruise
control cannot be activated.
• BPP switch – The BPP switch tells the PCM whether thevehicle is being braked. In its rest state the
switch is closed and sends an earth signal
to the GEM. This signal is sent via the CAN
to the PCM.
– The brake light switch is likewise connected to the GEM and is opened in the rest state.
When the vehicle is braked, the brake light
switch sends a signal to the GEM. This
compares the signals from the BPP switch
and the brake light switch. If a discrepancy
occurs, a fault is stored in the error memory
of the GEM. Cruise control cannot be
activated.
• CPP switch – The CPP switch sends a ground signal to theGEM as soon as the clutch is operated. This
signal is passed on by the GEM via the CAN
bus to the PCM. This then supplies the signal
to the cruise control.
– If the CPP switch is incorrectly installed or set, cruise control cannot be activated.
• Wheel speed sensors – The wheel speed sensors record the speedof all the wheels. The recorded speed values
are sent to the ABS module via a hard-wired
connection. The ABS module calculates a
vehicle speed signal (VS signal) from the
speed values and the wheel diameter. This
vehicle speed signal is transferred via the
CAN bus to the PCM and supplied to the
cruise control. If the vehicle speed signal is
faulty, cruise control cannot be activated.

Refrigerant Circuit - Quick Check
WARNING: The air conditioning system is
filled with refrigerant R134a. Observe
"Health and Safety Precautions". For
further information
REFER to: Air Conditioning (A/C) System
Recovery, Evacuation and Charging
(412-00 Climate Control System - General
Information, General Procedures).
Refrigerant circuit check
WARNING: Under certain circumstances,
refrigerant lines and A/C components may
be extremely hot or cold. Exercising care,
touch the refrigerant lines or A/C
components in order to check this. Failure
to follow these instructions may result in
personal injury.
When the A/C system is operating, the following
conditions should apply:
• The refrigerant line from the refrigerant compressor to the condenser must be hot.
• The refrigerant line from the A/C condenser to the fixed orifice tube must be warm, but not so
hot as the refrigerant line mentioned above.
• Determine the difference in temperature upstream and downstream of the A/C condenser
by measuring the temperatures at the refrigerant
lines. The temperature difference should be
more than 20° C, depending on the ambient
temperature. If the temperature difference is
less, check the condenser for contamination or
damage to the fins as well as operation of the
radiator fans.

FORD KUGA 2011.0MY WORKSHOP REPAIR MANUAL

• The refrigerant line between the fixed orificetube and the evaporator must be cold from the
point where the fixed orifice tube is installed.
Depending on the weather, the refrigerant line
may also have ice on its surface.
• The refrigerant line between the evaporator and the A/C compressor including the dehydrator
must be cold.
Evaporator outlet line temperature test
To test the power of the A/C system, the
temperature at the evaporator outlet line must be
measured. To do this, the following preconditions
must be met:
• Open all windows.
• Set the air distribution to the defrost/dashboardposition and open all the ventilation nozzles.
• DO NOT switch on recirculated air.
• Select lowest blower switch setting.
• Select lowest temperature setting.
NOTE: The temperature measurement cannot be
done with a thermometer which makes no contact.
The surface reflection from the metal line may
cause incorrect readings.
Connect the temperature sensor (Fluke 80 PK-8)
to the outlet line of the evaporator. Locate the
temperature sensor as close as possible to the
evaporator. Connect the temperature sensor to the
multimeter.
Start the engine and allow it to run at idle speed
for several minutes.
Switch on the A/C.
After three minutes, measure the surface
temperature of the evaporator outlet line.
If the temperature measured is 4° C or lower, the
A/C system is OK. If the temperature is higher, the
A/C system may be under-filled. For further
information, refer to
REFER to: Air Conditioning (A/C) System
Recovery, Evacuation and Charging (412-00
Climate Control System - General Information,
General Procedures).
Frequent faults and their causes
If the cooling power of the A/C system is not
adequate, make certain that the temperature
control flap(s) is/are operating correctly. • No or poor cooling performance:
– Blockage or narrowing of a refrigerant line orin the dehydrator. The location of the
blockage or narrowing can easily be located
by temperature comparisons at the
refrigerant lines and the dehydrator. The
blockage or restriction is located at the point
where the temperature difference is
identified. Note: A temperature difference
in the area of the fixed orifice tube is
normal. If the location of the blockage or
narrowing is found, check the corresponding
component and renew as applicable.
• Sudden drop in cooling performance (after the air conditioning has been switched off for
approx. 5 minutes, the cooling performance
returns to normal):
– The cause is an iced-up fixed orifice tubebecause of moisture in the refrigerant circuit.
In order to ensure that moisture is completely
removed from the refrigerant circuit, the
dehydrator should be renewed and the
evacuation time should be extended to 2-3
hours. For further information
REFER to: Air Conditioning (A/C) System
Recovery, Evacuation and Charging
(412-00 Climate Control System - General
Information, General Procedures).
Sequence of A/C Request Signal
NOTE: The electronic automatic temperature
control (EATC) module is integrated into the air
conditioning control assembly.
NOTE: The generic electronic module (GEM) is
an integral part of the central junction box (CJB).
After actuating the A/C ON/OFF switch integrated
into the A/C control assembly, an A/C request
signal is sent from the A/C control assembly
(vehicles with EATC: EATC module) to the GEM.
From there, the signal is sent to the instrument
cluster via the MS-CAN bus. A gateway is installed
in the instrument cluster, which establishes the
connection between the MS-CAN bus and the
HS-CAN bus.
After the signal has been converted in the gateway,
it is relayed to the powertrain control module (PCM)
via the HS-CAN bus. Once all the required
parameters have been met, the PCM switches on
the refrigerant compressor and thus the A/C system
via the A/C clutch relay.
