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.

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

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?
Change the coolant pressure sensor.YES
NOTop up the coolant.
Check that the coolant sensor connector is correctly engaged.
Engage the connector correctly if necessary.
