Reconnect the computer and the driver’s 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
pretensioners if there has
been a replacement (tool Elé. 1287).
Lock the computer using the command on the fault finding tool.
Disconnect the ignition module for the driver’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 (fault no longer declared present), check the condition of the seat wiring.
Replace the driver’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
D . If the value obtained is not correct, check the connections on the 30 track connector (tracks 1 and 2)
and replace the wiring if necessary
If the checks carried out do not indicate the presence of a fault on the driver’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 driver’s pretensioner line.
If the value is not correct, replace the wiring betweenpoints C1 and C3 (seat wiring).

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.

DF035
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.
