Check the voltage of the computer power supply : 9.5 volts < correct voltage < 17.5 volts.
If necessary, carry out the following operations :
- Check the battery charge (check the charging circuit if necessary).
- Check the tightness and condition of the battery terminals.
- Check the ABS earths (tightness of two earth bolts above the ABS assembly).
Disconnect the computer and check the condition and the positioning of the shunt in the 31 track
connector (between track 19 and track 21).
Check on the computer side, the condition of the shunt opening pin.

ABS COMPUTERFault chart 15
Only consult this section after a complete check with the XR25 kit.NOTES
If dialogue is still not established after these checks, replace the ABS computer.
Check that the diagnostic socket is receiving the correct power supply:
-+ before ignition on track 16,
-earth on track 5.
Check continuity and insulation of the lines of the diagnostic socket / ABS computer connections:
- 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.
Check the presence and condition of the ABS fuse on the passenger compartment connection unit (10A).
Check the connection of the computer connector and the condition of its connections.
Check the connection and condition of the connections at the R36 dashboard / ABS connector.
Check the ABS earth leads (tighten the two earth bolts above the ABS assembly).
Check that the computer is receiving the proper power supply :
- earth on track 19 of the 31 track connector,
- +after ignition on track 15 of the 31 track connector.
Ensure that the XR25 is not at fault by trying to communicate with a computer on another vehicle. If the
XR25 is not at fault and dialogue is not being established with another computer on the same vehicle, it is
possible that a faulty computer is disturbing diagnostic lines K and L. Proceed with successive disconnec-
tions to localise this computer.
Check that the ISO interface is in position S8, that you are using the most recent version of the XR25 kit
and the correct access code.
Check the battery voltage and carry out the operations necessary to obtain the correct voltage (9.4 volts
< U battery< 17.4 volts).

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.

Check if locking or unlocking the doors is possible by testing with the other key. If locking or unlocking of
the vehicle doors is possible, replace the battery in the first key.
On the infrared transmitter connector, check for + 12 V before ignition feed between tracks B2 and A3.
Is this voltage present ?
Set the XR25 to pulse sensor mode (button "G", input on terminal "Vin").
Check for pulses on track B2 of the infrared transmitter by pressing the PLIP (test
with the decoder unit and infrared transmitter connectors connected).
Are there any pulses when the PLIP is pressed?YES
YES Replace the decoder unit.
