NO Top up the coolant circuit.
Repair the circuit if necessary.
If left-hand bargraph 4 remains permanently illuminated, change
the clutch.
If left-hand bargraph 4 still remains permanently illuminated,
change the compressor.
Using the XR25, check the pressure of the circuit (# 16).
At an ambient temperature of approximately 20 °C, a pressure of between 2 and
28 bars should be measured.
Is the pressure between these values?
Enter G21* on the XR25 to control the compressor.
Does the compressor cut in?

Check that 12 volts is present on track 1 of the clutch connector.
Is 12 volts present?
Check the condition of the compressor earth.
Is the compressor earth in good condition?
YES Check the continuity and absence of short circuits of the electrical
wiring between the clutch and the compressor.
If the electrical wiring is faulty, repair it.
If the electrical wiring is in good condition, change the compressor.
NO Repair the compressor earth.
Check the continuity and absence of short circuits of the electrical wiring
between track 1 of the clutch and tracks 2 and 17 of the air conditioning control
unit 30-way connector.
Repair the electrical wiring if necessary.
For petrol vehicles:
Use the XR25 fiche which corresponds to the vehicle.
With the engine running, operate the AC then check on the XR25 fiche whether
the "Compression authorised or prohibited" status bargraph is illuminated.
Is the bargraph illuminated?
YES Check and repair the electrical wiring.
NO Refer to Left-hand bargraph 4 illuminated, cont 2.

Before carrying out any work, check that the customer uses the air conditioning
correctly.
Non regulated air conditioning.
Check that the compressor operates, with the
air conditioning on, passenger compartment
ventilation on maximum in recirculation
mode, engine running at idle.
Does the compressor operate?
Check the tension of the compressor belt, the
clutch air gap and its condition.
Retension the belt or change
the compressor clutch.
Does the fault persist?
yes
Ensure that the recirculation flap is in the
recirculation position in air conditioning
recirculation mode.
Is it in this position?
Check that the flap travel is complete,
readjust the cable if necessary.
Does the fault persist?

check that the compressor operates.
Does the compressor operate?
Connect the XR25 and enter G21*
(direct compressor control).
Does the compressor operate?
Check the pressure of the coolant circuit.
The compressor should cut in for:
- low pressure≥ 2 bars,
- high pressure≤ 28 bars.
Is this correct?
Check the wiring between
the heating and ventilation computer
and the compressor clutch.
Repair if necessary.
Check that the components which were removed are connected correctly.
