CO : Open circuit
CC : Short circuit
CC.0 : Short circuit to earth
CC.1 : Short circuit to 12 volts
1.DEF : Configuration
2.DEF : Short circuit between trigger lines
NOTESIf 1.DEF, check and modify the computer configuration using the configuration reading
LC043 Passenger's front chest-level side airbag, then adjust it if it is inconsistent
using the configuration CF224 Passenger's front chest-level side airbag.
Priorities when dealing with a number of faults:
If DF068 is present with fault DF184 Passenger's front buckle pretensioner circuit,
start fault finding by checking the under seat 8-track R334 connector.
Special notes:
Never carry out any measurements on the trigger lines using any tool other than the
XRBAG or CLIP diagnostic tool.
Use dummy module (part no. Elé. 1835 yellow) and the dummy module
(part no. Elé. 1837- 6).
IMPORTANT
Before disconnecting the airbag connector to fit a dummy module, always lock
the trigger lines using the diagnostic tool and command VP006 "Lock
computer".
Use the W iring Diagrams Technical Note, New TWINGO.
Lock the trigger lines using the command VP006 Lock computer.
Switch off the ignition.
Check the condition of the R334 connector under the passenger's front seat (see Wiring Diagram Technical
Note, New Twingo).
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. 1837- 6) on the 8-track R334 connector under the passenger's
front seat.
Switch on the ignition again.
Read the fault in the AIRBAG / PRETENSIONER field.
AFTER REPAIRClear 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''.

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 R334 connector under the
passenger's front seat.
Check the insulation (+ 12 V, to earth and between the 2 lines) and the continuity of the following
connections:
–Connection code 60B between component 756 and connector R334,
–Connection code 60C between component 756 and connector R334.
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 passenger's buckle front pretensioner component code 758 (see MR 411, Mechanical, 88C,
Airbag and pretensioners, Front buckle pretensioner: Removal - Refitting).
Check the condition of the passenger's front buckle pretensioner connector (see Wiring Diagram Technical
Note, New Twingo, Component code 758).
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 passenger's front buckle pretensioner connector
component code 758.
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.
