Remove :
- the air distribution unit,
- the heater unit radiator.REFITTING
Check :
- that the wiring is correctly routed behind the
dashboard,
- that the air ducts are correctly secured to pre-
vent noises developing.
Change the steering wheel bolt (pre-bonded bolt,
tightening torque : 4.5 daN.m).
IMPORTANT : Before reconnecting the AIR BAG
cushion it is necessary to apply the air bag system
operational check procedure :
• Check that the AIR BAG warning light on the
instrument panel is illuminated when the igni-
tion is switched on.
• Connect an inert ignition unit to the AIR BAG
cushion connector and check that the warning
light extinguishes.
• Switch off the ignition, connect the AIR BAG
cushion in place of the inert ignition unit and
secure the cushion on to the steering wheel.
• Switch on the ignition, check that the air bag
warning light illuminates for three seconds

ALL TYPES
ESTABLISHING XR25 / HEATING-VENTILATION CONTROL UNIT DIALOGUE
- Connect the XR25 to the diagnostic socket.
- ISO selector on S8
- Enter D17 n.61
PRECAUTION :
When carrying out checks using a multimeter, avoid using a contact tip on the connectors the size of which
could damage the clips and result in poor contact.
ERASING THE MEMORY:
After repairing the air conditioning system, enter G0** on the XR25 keypad to erase the fault stored.

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.

XR25 / CONTROL UNIT COMMUNICATION
1
None.NOTES
Fiche n° 61
Before establishing communication between the XR25 and the control unit, check that you have switched
on the ignition.
Ensure that the XR25 is not the cause of the fault by trying to communicate with a computer on another
vehicle.
Check that the ISO interface is in position S8 and that you are using the latest version of the XR25 cassette
and the correct access code (D 17).
Check the battery voltage (U > 10.5 volts). Recharge the battery if necessary.
Check that the control unit connectors are engaged correctly.
Check that the air conditioning control unit is supplied correctly:
- earth on track 4 of the red 15-way connector
-+ after ignition on track 1 of the blue 30-way connector
-+ after ignition on track 6 of the red 15-way connector
-+ fuse board on track 5 of the red 15-way connector
Check that the diagnostic socket is supplied correctly:
track K track 6of the air conditioning control unit
track L track 3blue 30-way connector
If there is still no dialogue between the XR25 and the control unit, change the air conditioning control
unit.

Check the continuity and insulation from earth of the electrical wiring between tracks A, B and C of the
sensor and tracks 9, 10 and 11 of the air conditioning control unit 30-way connector (sensor supplied with
5 V).
Repair the faulty electrical wiring.
Connect the XR25 and enter # 16. Measure the coolant pressure. The low pressure should be less than or
equal to 2 bars.
Is it correct?
