Use bornier Elé. 1332 for any operations on the computer connector.NOTES
When communication is established, deal with any fault bargraphs which may be
illuminated.
Ensure that the XR25 is not the cause of the fault by trying to communicate with the computer on ano-
ther vehicle. If the XR25 is not the cause of the fault and dialogue is not established with another compu-
ter on the same vehicle, a faulty computer may be causing interference on the K and L fault finding lines.
Disconnect connections successively to determine which computer is at fault.
Check the ISO selector is on position S8, that you are using the latest XR25 cassette and the correct access
code (D34).
Check the battery voltage and carry out any necessary operations to ensure the correct voltage (U battery
> 10.5 volts).
Check the 15 Amp fuses on the engine connection unit have not blown (positions 3 and 4).
Check the connection and condition of the connections on the computer connector and the connection
R67 engine / dashboard.
Check the computer is correctly fed:
- Earth on track 2 of the computer connector (check the condition and tightness of the engine earth
strap and the engine earth MH near to the gearbox housing).
- + after ignition feed on track 1 of the computer connector.
Check the diagnostic socket is correctly fed:
- Earth on track 5.
- + before ignition feed on track 16.
Check and ensure the continuity and insulation of the lines in the connection diagnostic socket/
computer:
- Between track 10 of the computer connector and track 15 of the diagnostic socket.
- Between track 13 of the computer connector and track 7 of the diagnostic socket.
If fault finding is not established after these operations, replace the computer (consult the "Aid" section
for this operation).
