If the value obtained is not correct , check the 30 track connector connection (tracks 1 and 2) and replace
the wiring if necessary.
If the checks carried out have not proven the existence of a fault, replace the airbag computer (consult
the section "Aid" for this operation).
Reconnect the ignition module of the driver’s pretensioner .

Never carry out measurements on the trigger lines with equipment other than the
XRBAG.NOTES
Lock the computer using command G80* on the XR25.
Disconnect the ignition module of the driver’s pretensioner and connect a dummy ignition module to
the ignition module connectors.
Switch on the ignition and carry out an XR25 check.
If the fault has been memorised (fault no longer declared), check the condition of the seat wiring.
Replace the driver’s pretensioner if the wiring is not faulty.
Then carry out the same operation on the Passenger’s pretensioner (if not a driver’s side fault ).
The XRBAG tool MUST be used for measuring insulation appropriate to the type of fault at point C1 (seat
connector) of the driver’s pretensioner line.
If the value obtained is not correct , replace the wiring between points C1 and C3 (seat wiring).
Then carry out the same measurement on the passenger’s pretensioner line (if not a driver’s side fault ).
Disconnect the computer connector and fit the 30 track adaptor.
The XRBAG tool MUST be used for measuring insulation appropriate to the type of fault on the adaptor
wires marked D (Passenger ) and E (Driver ) .
If one of the values obtained is not correct, check the 30 track connector connection (tracks 3 / 4 for wire
D and 1/2 for wire E) and replace the wiring if necessary .
If the checks carried out have not proven the existence of a fault, replace the airbag computer (consult
the section "Aid" for this operation).
Reconnect the ignition modules of the seat belt pretensioners.
Erase the computer memory using the command G0** then switch off the ignition.
Carry out another XR25 check and if there is no fault, unlock the computer using

If the checks carried out have not proven the existence of a fault, disconnect the computer connector and
fit the 30 track XRBAG adaptor . Use the XRBAG in testing mode to check the operation of the warning
light on the instrument panel from the grey adaptor wire.
If it is possible to illuminate the warning light using the XRBAG, replace the airbag computer (consult
the section "Aid" for this operation).
If it is impossible to operate the warning light , repeat the preceding checks.

Fault finding - Interpretation of XR25 bargraphs
Bargraph 14 left hand side Fiche n° 49
Computer locked 14
NoneNOTES
This bargraph 14 left hand side allows computer locked status to be seen .
When it is illuminated, all trigger lines are inhibited, preventing the release of the airbags and the seat
belt pretensioners.
This bargraph is normally illuminated in two situations :
- The computer is new (it is sold in locked mode).
- The XR25 computer locking command has been used during an operation on the vehicle
(G80*).
Erase the computer memory using the command G0** then switch off the
ignition. Carry out another XR25 check and if there is no fault, unlock the
computer using command G81*.AFTER REPAIR

Fault present before impact 14
NoneNOTES
This bargraph is normally illuminated in the following situations :
- An impact has been detected.
- A fault was present in the computer memory before the impact.
- This fault was declared by the illumination of the fault warning light before the impact .
Bargraph 14 left hand side can in this way justify non-release of an airbag or a seat belt pretensioner .
Consult the Techline if this bargraph is illuminated in other situations (no fault, no impact, ...).
