System Operation
Speed Control
Cruise control is integrated into PCM and
intervenes in engine management to automatically
keep to the target speed selected by the driver.
When the system is active, the vehicle can be
accelerated or decelerated without the accelerator
pedal being pressed. Cruise control is operated
using the control switch units on the steering wheel.
The PCM controls the throttle to achieve this. The
ABS module supplies the VSS signal for this.
On vehicles with automatic transmission, the TCM
receives a notification via the CAN (controller area
network) bus that cruise control is active. The TCM
then controls the transmission based on special
engine maps.
Cruise control recognizes three operating modes:
• "OFF": Control is switched off.
• "STANDBY": Control is switched on but not
active. The speed of the vehicle is not regulated
by the cruise control.
• "ACTIVE": Control is switched on and active. Cruise control adjusts the vehicle speed to the
stored or desired target speed.
Every time the engine is started, cruise control is
in the "OFF" mode. In this mode, only the "ON"
button is operable.
Cruise control is initially set to "STANDBY" mode
when the "ON" button is pressed. The green cruise
control indicator lamp in the instrument cluster
lights up. There is no target speed saved.
Cruise control can only be set to "STANDBY" mode
under the following conditions:
• Engine speed is between idle speed and maximum permissible speed. Cruise control can only be changed into "ACTIVE"
mode under the following conditions:
• 2nd - 6th gear engaged.
• Engine speed between idle speed and maximum
permissible speed.
• Vehicle speed at least 40 km/h.
Pressing the "SET+" or "SET-" button activates
cruise control ("ACTIVE" mode). The green "Cruise
control" indicator lamp in the instrument cluster
lights up. The current vehicle speed is saved as
the target.
In "ACTIVE" mode the "OFF", "SET+", "SET-" and
"RES" buttons are active. If the "RES" button is
pressed again, control is suspended. The "RES"
button has a dual function and is used to resume
and suspend the cruise control.
Tapping the "SET+" button (for less than 640 ms)
increases the target speed by 1 km/h at a time.
Holding down the "SET+" button (for longer than
640 ms) increases the target speed until the button
is released. If the button is not released, cruise
control accelerates the vehicle up to the maximum
permissible vehicle speed (200 km/h) or up to the
vehicle's maximum speed (whichever speed is
lower). Tapping the "SET-" button (for less than
640 ms) reduces the target speed by 1 km/h at a
time. When the the "SET-" button is held down, the
control reduces the target speed until the button is
released. If the "SET-" button is held down until
the minimum speed of 40 km/h is reached, cruise
control switches to "STANDBY" mode.
Cruise control is put into "STANDBY" mode when
the "RES" button is pressed. Control to the stored
target speed can be started again by pressing the
"RES" button again. If the "SET+" or "SET-" button
is pressed while the "RES" function is being
performed (control to saved target speed), cruise

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.

Electronic Leak Detection
1.Refer to: Air Conditioning (A/C) System Health
and Safety Precautions (100-00 General
Information, Description and Operation).
2. WARNINGS:
Before starting leak detection, make
sure that the area where it is to be done
is well ventilated. If the surrounding air
is contaminated with refrigerant gas, the
leak detector will indicate this gas all
the time. Odors from other chemicals
such as antifreeze, diesel fuel, disc
brake cleaner, or other cleaning
solvents can cause the same problem.
Prevent air movement while performing
leak detection.
The refrigerant identification equipment
must be used before attaching the
manifold gauge set. Otherwise the
manifold gauge set may become
contaminated. Contaminated refrigerant
must be disposed of as special waste.
Follow the manufacturer's instructions
when working with the service unit.
NOTE: At 24°C with the engine switched off,
both manifold gauges should show 4.1 to 5.5
bar.
Attach the manifold gauge set to the service
gauge port valves.
3. For the leak test, close the manual valves on
the gauge set.
4. If little or no pressure is indicated, charge the
system with approx. 300g of refrigerant. Refer
to: Air Conditioning System - Evacuate and
Refill.
5. Use the R-134a Automatic Calibration Halogen
Leak Detector to leak test the refrigerant system.
Follow the instructions included with leak
detector for handling and operation techniques.

The engine driven refrigerant compressor (2) sucks
in gaseous refrigerant from the suction accumulator
and compresses it. The temperature of the
refrigerant rises to a value between 70 °C and 110
°C. It passes to the condenser (1) under high
pressure.
At this point heat is drawn from the refrigerant by
the air being forced past the cooling fins. Because
of this heat loss, the refrigerant liquefies and leaves
the condenser.
A fixed orifice tube (6), which separates the
refrigerant at high pressure from that at low
pressure, is located between the condenser and
the evaporator (5). This fixed orifice tube slows
down the flow of the refrigerant from the compressor, so that pressure builds up in the
condenser.
After passing through the fixed orifice tube the
liquid refrigerant expands in the circuit to the
evaporator, where it becomes gaseous. This
causes heat to be extracted from the air coming
into the vehicle. The air cools down, and excess
moisture contained in it is condensed and is
drained off. The refrigerant coming from the
evaporator flows into the refrigerant accumulator
and is again sucked in by the refrigerant
compressor.
The system is protected by a high-pressure limiting
switch, in order to prevent damage by excessive
pressure (e.g. because of overfilling with
refrigerant). If the pressure exceeds the maximum
