Lock the computer using the command on the fault finding tool.
Disconnect the ignition module for the passenger’s pretensioner and connect a dummy ignition module
to the ignition module connector.
Switch on the ignition and carry out a check using the fault finding tool.
If the fault is memorised (no longer declared as present), check the condition of the seat wiring.
Replace the passenger’s pretensioner if the wiring is not faulty.
Disconnect the computer connector and fit the 30 track B40 adaptor.
The XRBAG must be used for insulation measurements appropriate to the type of fault on adaptor cable
C . If the value is not correct, check the connections on the 30 track connector (tracks 3 and 4) and replace
the wiring if necessary
If the checks carried out do not indicate the presence of a fault on the passenger’s pretensioner circuit,
check on the air bag computer base for the 5 shunt opening pins for the 30 track adaptor.
Check the condition of the computer connections.
Check the condition of the 30 track connector (locking system, ...).
The XRBAG must be used for insulation measurements appropriate to the type of fault on point C1 (seat
connector) on the passenger’s pretensioner line.
If the value is not correct, replace the wiring betweenpoints C1 and C3 (seat wiring).
Reconnect the computer and the pretensioner ignition module, switch the ignition on
again. Erase the computer memory, then switch off the ignition. Carry out a check using
the fault finding tool and, in the absence of a fault, unlock the computer. Destroy the
pretensioner if there has been a replacement (tool Elé. 1287).

Computer locked
DF034
present
None.NOTES
This fault enables the locked condition of the computer to be seen.
When it is present, all trigger lines are inhibited, which prevents triggering of the air bags and seat belt
pretensioners.
This fault is normally present in two circumstances :
- The computer is new (it is sold locked).
- The computer locking command on the fault finding tool has been used during an operation on the
vehicle.
Erase the computer memory and switch off the ignition.
Carry out a check using the fault finding tool and, in the absence of a fault,
unlock the computer.

present
None.NOTES
This fault is normally present following an impact in the presence of memorised faults
This locking prevents accidental erasing of the registered contexts of impacts which lead to the systems
being triggered (the contexts are erased using the erasing command for the fault memory).
These contexts will be used later to simplify the repair of vehicles involved in accidents and also for
examination needs .
Erase the computer memory and switch off the ignition.
Carry out a check again using the fault finding tool.

The presence of this fault corresponds to an incoherence detected by the computer between the
computer configuration and the vehicle equipment.
The vehicle must be fitted with triggering lines which are not declared in the computer configuration,
especially the driver’s front air bag triggering line.

NOTES
Erase the computer memory.
For a micro-cut fault, check the computer supply lines :
- condition of the connections on the computer,
- the condition of the computer earths (tracks 6 and 30 on the 50 track connector to the front right pillar
earth).
- condition/ position of the fuse,
- condition and tightness of the battery terminals.
NoneNOTES 1.dEF
Carry out the operations necessary to obtain the correct supply voltage for the computer :
9 volts ± 0.1 < correct voltage < 18 volts ± 0.1.
- Check the battery charge.
- Check the charging circuit.
- Check the tightness and condition of the battery terminals.
- Check the computer earth.

The XRBAG must be used to measure resistance at point C2 of the driver’s air bag circuit.
If the value obtained is not correct, replace the rotary switch under the steering wheel.
Reconnect the rotary switch under the steering wheel, disconnect the computer connector and fit the 50
track B50 adaptor.
The XRBAG must be used to measure resistance on adaptor cable C .
If the value obtained is not correct,
check the connections on the 50 track connector (tracks 10 and 11)
and replace the wiring if necessary.
If there is no evidence of a fault after these checks have been carried out, check on the air bag computer
base for the 7 shunt opening pins for the 50 track connector.
Check the condition of the computer connections
Check the condition of the 50 track connector (locking system).
With the ignition switched off, disconnect then reconnect the rotary switch connector under the steering
wheel.
