Check that lines K and L are not being disrupted by another computer.NOTES
Fiche n° 56
Check the condition of +before ignition feed fuse.
Change the fuse if necessary.
Ensure that the XR25 kit is not the cause of the fault by trying to communicate with another computer on
the vehicle (air conditioning computer, injection computer...).
Check that the ISO interface is in position S8, that the most recent version of the XR25 cassette and the
correct access code are being used(D 56).
Check battery voltage (U > 10.5 volts). Recharge the battery if necessary.
Check that the 18 track decoder unit connector is properly connected.
Check that the decoder unit is properly fed :
-earth on track A8 of the decoder unit connector.
-+ before ignition feed on tracks A9 and A1 of the decoder unit connector.
Ensure that the diagnostic socket is correctly fed.
Check and ensure the continuity and insulation of the wiring of tracks A3 and A4 of the decoder unit
connector.
If there is still no dialogue between the XR25 kit and the decoder unit, change the decoder unit.

Lines K and L are shared between several computers, which can disrupt them. If
the fault persists, it would be prudent to check that they are not disrupting lines K
and L.
NOTES
Ensure that the XR25 is not the cause of the fault by trying to communicate with another computer on the
vehicle (air conditioning computer, injection computer ...).
Check that the ISO selector is on position S8 , that you are using the latest XR25 cassette and and the correct
access code (D56).
Check the battery voltage (U > 10.5 volts). Recharge the battery if necessary.
Ensure that the diagnostic socket is correctly fed.
