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.

For petrol vehicles:
Use the XR25 injection fiche which corresponds to the vehicle.
With the engine running, operate the AC then check on the XR25 fiche whether the " AC authorisation"
status bargraph is illuminated.
Is the bargraph illuminated?
There is a problem at the injection end.
Refer to the injection fault finding procedure which corresponds to the vehicle.
Check the continuity and absence of short circuits of the electrical wiring.
Repair if necessary.
Check that 12 volts is present on tracks 2 and 17 of the air conditioning control
unit 30-way connector.
Is 12 volts present?
YES There is a problem at the injection end.
Refer to the injection fault finding procedure which corresponds to
the vehicle.
NO Check whether the evaporator temperature sensor is in place.
Check its resistance: disconnect the evaporator temperature sensor
and measure the resistance at its terminals. The resistance measured
should be between 90 ohms and 13.7 kohms.
If the evaporator temperature sensor is in good condition, change
the air conditioning control unit.
If the evaporator temperature sensor is not in good condition,
change it.
