CONDITIONS FOR APPLICATION FOR THE TESTS DEFINED IN THIS FAULT FINDING
The tests described in this fault finding are only to be applied when the wording of the fault corresponds
exactly to the display on the XR25 kit.
If a fault is dealt with because there is a flashing bargraph, the conditions for confirming the existence of an
actual fault (and the need to apply the fault finding ) can be found in the "Notes" or at the beginning of the
bargraph interpretation.
If a bargraph is only interpreted when it is permanently illuminated, the application of the recommended
tests in the fault finding when the bargraph is flashing will not allow you to determine the origin of the
memorisation of this fault. In this case, only a test of the wiring and the connections of the component in
question must be carried out (the fault is simply memorised as it was not present at the time of testing).
NOTE : The ignition must have been switched off before the XR25 kit is used.
INDISPENSABLE TOOLING REQUIRED FOR OPERATIONS ON THE ABS SYSTEM
- XR25 kit.
- XR25 cassette n° 16 minimum.
Reminders :When there is intermittent fault memorisation, the ABS warning light will illuminate the next
time the vehicle is used until the car reaches 7.5mph (12 km/h). When the fault is memorised, a
counter relating to the fault is set at 40 . This value is reduced by one each time the ignition is
turned on if the fault is not present when the vehicle exceeds 7.5mph (12 km/h). When the
reading on the counter is equal to 1, it remains at 1 and the fault is not erased.

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.
