Repair if necessary.
Turn the engine.
Switch the ignition off and wait for the loss of dialogue between the XR25 and the computer.
Switch the ignition on.
Enter dialogue with the computer.
Erase the computer memory using G0**.
NOTE :memorised faults are erased. It would therefore be useful to carry out a road test to check there
are no faults on the injection system.

If # 04 < Minimum, the battery is discharged:
Check the charging circuit to determine the cause of this fault.

If # 04 > Maximum, the battery may be overcharged:
Check the charging voltage is correct with and without consumers.
If # 04 < Minimum, the charging voltage is too low:
Check the charging circuit to determine the cause of this fault.
At idle speed
If # 04 > Maximum, the charging voltage is too high:
The alternator regulator is faulty. Repair this fault and check the electrolyte level in the battery.
NOTE:
The battery and the charging circuit may be checked using the OPTIMA 5800 station (measurement does
not require the battery to be disconnected, which retains the memories of the computers).

If the information obtained by the XR25 requires electrical continuities to be checked, connect bornier Sus
1228.
Bornier Sus 1228 is a 55 track base with a printed circuit on which are 55 copper coated surfaces, numbered
from 1 to 55.
Using the wiring diagrams, the tracks connecting the components to be tested can be easily identified.
IMPORTANT :
• All tests using bornier Sus 1228 must be carried out with the battery disconnected.
• The bornier is only designed to operate with an ohmmeter. Under no circumstances should 12 Volts be
applied to the test points.

Check that the XR25 kit is not the cause of the fault by trying to communicate with the computer of
another vehicle. If the XR25 kit is not at fault and it will not communicate with any other computer in the
same vehicle, it is possible that a faulty computer is corrupting fault finding lines K and L . Locate this
computer by disconnecting the lines one by one.
Check that the ISO interface is correctly in position S8 and that you are using the most recent XR25
cassette and the correct access code.
Check the battery voltage and carry out the necessary operations to obtain the correct voltage(9.4Volts<
U battery<17.4Volts)
Check the presence and condition of the ABS fuse on the connection unit of the passenger compartment
(10A).
Check the connection of the computer connector and the condition of its connection.
Check the connection and condition of the connection at the R36 dashboard / ABS connection.
Check the ABS earth wires (tighten the two earth screws above the ABS assembly).
Check that the computer is correctly fed :
-earth on track 19 of the 31 track connector,
-+ after ignition feed on track 15 of the 31track connector.
Check that the diagnostic socket is correctly fed :
-+ before ignition feed on track 16,
-earth on track 5.
Check the continuity and insulation of the lines in the diagnostic socket / ABS computer connection:
- between track 12 of the computer connector and track 15 of the diagnostic socket,
- between track 11 of the computer connector and track 7 of the diagnostic socket.
If dialogue is still not established after these tests, replace the ABS computer.,
When communication is established, deal with any fault bargraphs which may be
illuminated. AFTER REPAIR
