ALL TYPES
REPRESENTATION OF BARGRAPHS
REPRESENTATION OF FAULTS (always on a coloured background)
If illuminated, this indicates a fault on the component in question, the associated text defines
the fault.
REPRESENTATION OF STATUS (always on a white background)
Illuminates when dialogue is established with the component computer, if it remains
extinguished:
- the code does not exist,
- there is an equipment, computer or line fault.
Engine stopped, ignition on, no operator action
The status bargraphs on the fiche are represented as they should appear with the engine stopped, ignition
on and no operator action.
- If on the fiche, the bargraph is represented the XR25 should display
- If on the fiche, the bargraph is represented the XR25 should display

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.

NOTES
Fiche n° 61
This bargraph should be extinguished when the engine is running.
If it is illuminated, you can begin the fault finding procedure.
First check that the air conditioning has been selected (selection on the control panel).
Check the continuity of the electrical wiring between track 5 of the injection computer and track 13 of
the air conditioning control unit 30-way connector (P.A. information).
Repair it if necessary.
Check the continuity of the electrical wiring between:
- track 51 of the injection computer and track 18 of the AC computer 30-way connector for D7F and E7J
engines,
- track 19 of the injection computer and track 18 of the AC computer 30-way connector for F8Q engines.
Repair it if necessary.
If the problem persists, check the injection fault finding procedure, as it is a problem related to the
injection.
