SYMBOLISATION OF THE BARGRAPHS
- Of faults (always on coloured background) :
If illuminated, signals a fault on the product tested. The associated text
describes the fault.
This bargraph may be:
- Illuminated : fault present.
- flashing : fault memorised.
- Extinguished : fault absent or not found.
- Of status (always on white background) :
Bargraph is always on the upper right hand side
If illuminated, this signals the establishment of dialogue with the product computer
If it remains extinguished :
- The code does not exist.
- There is a fault in the XR25, the computer or the XR25/computer connection.
The representation of the following bargraphs indicates their initial status:
Initial status : (ignition on, engine stopped, without operator action).
Indefinite
illuminated when the function or condition specified on the fiche is
met
Extinguished
Illuminated extinguished when the function or condition specified on the fiche is
no longer met.
- Supplementary information:
Certain bargraphs have a *. Command*.., when the bargraph is illuminated, allows supplementary
information on the type of fault or status arising to be displayed.

NOTES
Fiche n° 53
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.
