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.

Fiche n° 60 1/2
Bargraph 1 RH extinguished
Code present
1
Use bornier Elé. 1332 for any operations on the computer connector.NOTES
When communication is established, deal with any fault bargraphs which may be
illuminated.
Ensure that the XR25 is not the cause of the fault by trying to communicate with the computer on ano-
ther vehicle. If the XR25 is not the cause of the fault and dialogue is not established with another compu-
ter on the same vehicle, a faulty computer may be causing interference on the K and L fault finding lines.
Disconnect connections successively to determine which computer is at fault.
Check the ISO selector is on position S8, that you are using the latest XR25 cassette and the correct access
code (D34).
Check the battery voltage and carry out any necessary operations to ensure the correct voltage (U battery
> 10.5 volts).
Check the 15 Amp fuses on the engine connection unit have not blown (positions 3 and 4).
Check the connection and condition of the connections on the computer connector and the connection
R67 engine / dashboard.
Check the computer is correctly fed:
- Earth on track 2 of the computer connector (check the condition and tightness of the engine earth
strap and the engine earth MH near to the gearbox housing).
- + after ignition feed on track 1 of the computer connector.
Check the diagnostic socket is correctly fed:
- Earth on track 5.
- + before ignition feed on track 16.
Check and ensure the continuity and insulation of the lines in the connection diagnostic socket/
computer:
- Between track 10 of the computer connector and track 15 of the diagnostic socket.
- Between track 13 of the computer connector and track 7 of the diagnostic socket.
If fault finding is not established after these operations, replace the computer (consult the "Aid" section
for this operation).

1.dEF
This fault indicates that the advance corrector is seized, the injection pump has been incorrectly set or
there is a fuel supply fault.
It is taken into account when the advance noted by the needle lift sensor differs by more than 5° from the
advance value requested by the computer.
NOTE : If there is a fault where the advance corrector is seized, there will be a characteristic noise when
the ignition is switched on (irregular clicking of the corrector).
The fault is present if the bargraph is illuminated when the engine is
running.NOTES

CONT
- Check the condition of the fuel supply to the pump and the injectors (filter blocked, pipe kinked, air
leak, ...).
Check the type of diesel fuel used in extreme cold weather (a "summer " type diesel fuel may cause
this fault at -15 °C).
- Check the pump timing and check the tightness of the pump pulley.
- If the fuel supply and the pump timing are correct, replace the advance corrector.
