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.
6. If any leak is found, extract the refrigerant under
suction. Refer to: Air Conditioning System -
Evacuate and Refill.

Fault Memory Interrogation without
diagnostics unit - vehicles with
automatic temperature control
NOTE:On vehicles equipped with a DVD
navigation system with touchscreen, the fault
memory can only be interrogated using the Ford
diagnostic tool.
The climate control and heating system features
a on-board diagnosis function which can detect
and store both current permanent faults as well as
intermittent faults which have occurred during
normal operation of the vehicle. It is also possible
to read out these faults via the display on the
control panel of the climate control system. To read
out the fault memory, the ignition key must be
turned to the "ON" position and the battery voltage
must be between 9 V and 16 V.
To activate the on-board diagnosis at the control
panel for the climate control system, PRESS the
"OFF" and "FOOTWELL" buttons simultaneously
for exactly 2 seconds, then PRESS "AUTO" within
1.5 seconds. The on-board diagnosis which then
starts lasts a few seconds. An animated display
appears in the display of the control panel for the
climate control system during this time. Any faults
found are displayed on both displays of the control
panel for the climate control system in the form of
trouble codes.
To read out saved errors at the control panel for
the climate control system, PRESS the "OFF" and
"FOOTWELL" buttons simultaneously for exactly
2 seconds, then PRESS "HEAD AREA" within 1.5
seconds. Any stored faults are shown on the
display of the control panel for the climate control
system and should be noted for safety reasons.
By PRESSING the "DEFROST" button, the fault
memory is cleared and diagnosis mode is ended.
To end the diagnostic mode without clearing the
DTCs, PRESS any other operating button on the
control panel for the climate control system.
To read out the software version at the control
panel for the climate control system, PRESS the
"OFF" and "FOOTWELL" buttons simultaneously
for exactly 2 seconds, then PRESS "A/C" within
1.5 seconds. The software version is shown on the
display of the control panel for the climate control
system. The output mode can be exited by
PRESSING any button on the control panel for the
climate control system.
Switch over from Celsius to Fahrenheit
The switch from Celsius to Fahrenheit is performed
on the display of the instrument cluster and is then
transmitted via the CAN bus to the module of the
two-zone air conditioning system.

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
