Lock the computer using the command on the fault finding tool.
Switch off the ignition and remove the 2 steering wheel boss mounting bolts.
Check that it is connected correctly.
Disconnect the steering wheel boss and attach a dummy ignition module to the ignition module
connector. Switch on the ignition and carry out a check using the fault finding tool.
Replace the air bag cushion if the fault has been memorised (fault no longer declared present).
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 30
track B40 adaptor.
The XRBAG must be used to measure resistance on adaptor cable A .
If the value obtained is not correct,
check the connections on the 30 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 5 shunt opening pins for the 30 track connector.
Check the condition of the computer connections
Check the condition of the 30 track connector (locking system, ...).
With the ignition switched off, disconnect then reconnect the rotary switch connector under the steering
wheel.
Repair the connections if the fault has just been memorised (fault no longer declared 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.
