Inspection and Checking
NOTE:The electronic automatic temperature
control (EATC) module is integrated into the air
conditioning control assembly.
1. VERIFY customer concern.
2. Visually CHECK for any obvious mechanical or electrical damage.
NOTE: Ensure correct locking of the wiring harness
connector.
Visual Inspection
Electrical
Mechanical
• Fuses
• Wiring harness
• Connector
• Refrigerant lines
• Condenser core
• Coolant level
• Drive belt
• A/C compressor
3. RECTIFY any obvious causes for a concern found during the visual inspection before
performing any further tests. CHECK the
operation of the system.
4. If the concern is still present after the visual inspection, perform fault diagnosis on the
electronic engine management, the charging
system, the generic electronic module (GEM)
and the instrument cluster (vehicles with EATC:
read out the EATC fault memory as well) using the Ford approved diagnostic tool and RECTIFY
the fault(s) displayed in accordance with the
fault description. CHECK the operation of the
system.
5. For vehicles with no stored fault(s), PROCEED in accordance with the Symptom Chart
according to the fault symptom.
6. Following checking or elimination of the fault(s) and after completion of operations, the fault
memories of all vehicle modules must be READ
OUT and any stored faults must be DELETED.
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.

• 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.

Fluorescent Dye Leak Detection
General EquipmentUV Leak Detector
1. Refer to: Air Conditioning (A/C) System Health
and Safety Precautions (100-00 General
Information, Description and Operation).
2. NOTE: Some vehicles may have signs of
refrigerant oil at the spring lock couplers. The
cause of this may be a procedure used in
production before installation of the fittings in
order to assist their assembly. When a spring
lock coupler is suspected of leaking, always
wipe the fitting clean and verify the leak with
R-134a Automatic Calibration Halogen Leak
Detector.
NOTE: The exact location of leaks can be
pinpointed by the bright yellow - green glow of
the tracer dye. Since more than one leak can
exist, always inspect each component.
• Locate the leaks. Check all components, fittings and lines of the A/C system for leaks.
General Equipment: UV Leak Detector
3. After the leak is found and rectified, remove any
traces of dye with a general purpose solvent.
4. Check the repair by operating the system for
some minutes and inspecting with the UV lamp
again.
