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.

Does the fault persist?
With the ignition on and the air conditioning
selected, position the ventilation at the
various speeds and check that 12 V
is present on the tracks of the
control panel connector:
