Check that equipment causing the problem during use is approved.
Check that this equipment has been correctly installed without modification to the original wiring, in
particular, that of the ABS (connections to earth and + after ignition/ before ignition of the ABS are not
permitted).

LACK OF COMMUNICATION WITH
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).

DESCRIPTION OF BARGRAPHS
Illuminates when dialogue is established with the product computer, if it remains extinguished :
- the code does not exist,
- there is a line , computer or tool fault.
REPRESENTATION OF FAULTS (always on coloured background)
Illuminated, indicates a fault on the part tested, the associated text defines the fault.
Extinguished, indicates non-detection of fault on the product tested.
REPRESENTATION OF STATUS (always on white background)
Engine stopped, ignition on, no operator action
Status Bargraphs on the fiche are shown as they should appear, engine stopped, ignition on, without

Check the condition of +before ignition feed fuse.
Change the fuse if necessary.
Ensure that the XR25 kit 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 interface is in position S8, that the most recent version of the XR25 cassette and the
correct access code are being used(D 56).
Check battery voltage (U > 10.5 volts). Recharge the battery if necessary.
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.
