bargraphs.
Carry out a conformity check.
Fault Chart 1NO XR25 / COMPUTER COMMUNICATION
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.
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 and the decoder unit , replace the decoder unit .
Check that the 18 track decoder unit connector is correctly connected.
Check that the decoder unit is correctly fed :
-earth on track A8 of the decoder unit connector
-+ before ignition feed on track A9 of the decoder unit connector.
Check the condition of the +before ignition fuse.
Replace the fuse if necessary.
