Check that the air conditioning has been selected.
Check that right-hand bargraph 6 is extinguished, if it is not, deal with right-hand
bargraph 6 first.
Enter G0** on the XR25.
If left-hand bargraph 6 remains illuminated, you can begin the fault finding
procedure.
Check the condition of the earth of fan assembly (2) (the relay is controlled by 0 volt).
Repair the fan assembly earth if necessary.
Connect the XR25 and enter # 16. Check that the coolant pressure is approximately 20 bars.
If it is not, top up the coolant (operation of the cooling fan assembly is dependent on the coolant
pressure).
NOChange the relay of fan assembly (2).
YESCheck the continuity and insulation from 12 volts of the electrical wiring
between track F2 and track 23 of the air conditioning control unit 30-way
connector.
Repair the faulty electrical wiring.
Check the condition of the wiring between the relay of fan assembly (2) and track 10 of the injection
computer.
Repair it if necessary.
Check the operating status of the relay by entering G23* on the XR25.
The fan assembly should be heard to knock.
Is the fan assembly heard to knock?

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.

Place the passenger compartment
fan on full,
temperature control on
maximum heat or maximum cold,
and move the air distribution control.
Check that the air output
corresponds to the selection.
Is it correct?
The air distribution is correct.
If necessary, explain how the system works to
the customer again.
Check visually or by touch, on the right-hand
side of the air distribution unit,
that moving the control
moves the sprockets
and the lever.
Do they move?
Check the connection of the cable
to the air distribution unit
and the control panel
and check the condition of the cable and its
retainer. Is it correct?Change the control cable
or repair the connection of the cable (clip)
or change the faulty part
(control panel or distribution unit).
If the fault persists,
remove the air distribution unit and
check the distribution flaps.
Repair or change the assembly.
In the case of a ventilation problem,
check the ventilation ducts
and the vents.
Repair if necessary.
Check the adjustment of the air distribution
flap control cable.
