If the fault remains "Present":
Check the condition of the airbag computer connector component code 756 (see Wiring Diagram Technical
Note, New Twingo, Component code 756).
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Faulty wiring between the airbag computer component code 756 and the 8-track R335 connector under the
driver's seat.
Check the insulation (+ 12 V, to earth and between the 2 lines) and the continuity of the following
connections:
–Connection code 60D between component 756 and connector R335,
–Connection code 60E between component 756 and connector R335.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
If the fault has become "Stored":
Switch off the ignition.
Remove the driver's buckle front pretensioner component code 757 (see MR 411, Mechanical, 88C, Airbag
and pretensioners, Front buckle pretensioner: Removal - Refitting).
Check the condition of the driver's buckle front pretensioner connector component code 757 (see Wiring

If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Position the dummy module (part no. Elé. 1835 yellow) on the driver's buckle front pretensioner connector
component code 757.
Switch on the ignition again.
Read the fault in the AIRBAG / PRETENSIONER field.
AFTER REPAIRReconnect the computer and the locking switch, then switch on the ignition again.
Clear the computer fault memory using command RZ001 "Fault memory". Switch
the ignition of f and then on again.
Repeat a check using the diagnostic tool and, if there are no faults (do not take the
DF034 "Computer locked'' into account), unlock the computer using the command
VP007 ''Unlock computer''.

DRIVER'S SEAT BELT BUCKLE SENSOR CIRCUIT
CC.1 : Short circuit to + 12 V
1.DEF: Short circuit
NOTESIf 1.DEF, check and modify the computer configuration using the configuration reading
LC073 Driver's seat belt buckle sensor, then adjust it if it is inconsistent using
configuration CF273 Driver's seat belt buckle sensor.
Priorities when dealing with a number of faults:
If DF232 is present with faults DF077 Driver's front side chest-level airbag circuit
and DF183 Driver's front buckle pretensioner circuit, start fault finding by checking
the 8-track R335 connector under the driver's seat.
Use the W iring Diagrams Technical Note, New TWINGO.
Check the condition of the driver's seat belt buckle sensor connector component code 333 (see Wiring Diagram
Technical Note, New Twingo, Component code 333).
Check the condition of the airbag computer connector component code 756 (see Wiring Diagram Technical
Note, New Twingo, Component code 756).
If the connector is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Use the "Universal bornier" to check the insulation to + 12 V, to earth and between the 2 lines of the following
connections:
–Connection code 60DU between components 756 and 333,
–Connection code 60DV between components 756 and 333.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
Use the "universal bornier" to check the continuity of the following connections:
–Connection code 60DU between components 756 and 333,
–Connection code 60DV between components 756 and 333.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
If the fault is still present, replace the driver's seat belt buckle sensor (see MR 411, Mechanical, 88C, Airbag and
pretensioners, Front buckle pretensioner: Removal - Refitting).
AFTER REPAIRReconnect the computer and front seat belt inertia reels, then switch on the ignition
again.
Clear the computer fault memory using command RZ001 "Fault memory". Switch
the ignition of f and then on again.
Repeat a check using the diagnostic tool and, if there are no faults (do not take the
DF034 "Computer locked'' into account), unlock the computer using the command
VP007 ''Unlock computer''.
