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

Erase the computer memory, exit the fault finding (G13*) and switch off the ignition.
Carry out a new XR25 test. If the "power supply / computer" fault persists, replace the ABS computer.
Check the condition and position of the 60A ABS fuse in the engine connection unit (white mounting).
Ensure continuity between this fuse and tracks 17 and 18 of the computer connector (presence of positive
before ignition feed on both tracks). Check the tightness and condition of the battery terminals.
Check the connections on the 31 track connector of the ABS computer.
Check the ABS earths (above the hydraulic assembly) and visually check all the ABS wiring.

Bargraphs 2, 3, 4 or 5 right or left hand side flashing
Solenoid valve circuit

Even if present at time of testing, these faults will always be declared by a
flashing bargraph.
To confirm their presence and therefore the need to apply the fault finding
described below start command G20*. The fault is present if the bargraph
appears illuminated at the end of the command.
If bargraph 11 left hand side is also illuminated, deal with bargraph 11 left hand
side as a priority.

Carry out operations necessary for obtaining correct voltage between tracks 19 and 17/18 of the 31-track
ABS computer connector (9.4 volts < correct voltage < 17.4 volts) :
- Check tightness and condition of battery terminals.
- Check the 60A fuse in the engine connection unit (white base).
- Ensure continuity between the 60A fuse and tracks 17 and 18 of the computer connector.
- Check the ABS earths (tightening of the two earth bolts above the hydraulic assembly).
- Check/ ensure continuity between the ABS earth and track 19 of the computer connector.
