CONDITIONS FOR APPLYING THE TESTS DESCRIBED IN THIS FAULT FINDING DOCUMENT
The tests described in this fault finding section should only be applied to the vehicle if the title of the fault
treated corresponds exactly to the display noted on the XR25 when the ignition is switched on.
If a bargraph is interpreted when flashing, the conditions for confirming the presence of an actual fault (and
the necessity of applying the fault finding) are shown in the "Notes" section or at the start of the bargraph
interpretation.
If a bargraph is only interpreted if it is permanently illuminated, the application of these tests recommended
in the fault finding document when the bargraph is flashing will not allow the cause of the memorised fault
to be determined. In this case, only checking of the wiring and connections of the faulty component should
be carried out (the fault is simply memorised as it was not present at the moment of testing).
NOTE: The ignition should be switched off before the XR25 is used.
SPECIAL TOOLING REQUIRED FOR OPERATIONS ON THE DPC DIGITAL INJECTION SYSTEM
- XR25 test kit.
- XR25 cassette N° 17 minimum.
- 25 track bornier Elé. 1332 for testing using the computer connector.

BARGRAPH SYMBOLS
FAULTS
(always on a coloured background)
If illuminated, there is a fault with the product tested. The associated text
defines the fault.
The bargraph may be :
- Permanently illuminated : fault present.
- Flashing : fault memorised
- Extinguished : no fault or not diagnosed
STATUS (always on a white background)
Bargraph always at the top right hand side.
If illuminated dialogue has been established with the computer for the product.
If it remains extinguished:
- The code does not exist.
- There is a fault with the tool, the computer or the XR25 / computer connection.
The representation of the following bargraphs indicates their initial status:
Initial status: (ignition on, engine stopped, no operator action)
Indefinite
- illuminated when the function or condition on the fiche is met.
Extinguished
Illuminated - extinguishes when the function or condition on the fiche is no
longer met
ADDITIONAL NOTES
Certain bargraphs have a *. The *.. command, when the bargraph is illuminated,
allows additional information on the type of fault or status to be displayed.
