1.DEF: Configuration
2.DEF: Short circuit between trigger lines
NOTESIf 1.DEF, check and modify the computer configuration using the configuration reading
LC042 Driver's front side chest-level airbag, then adjust it if it is inconsistent using
the configuration CF223 Driver's front side chest-level airbag.
Priorities when dealing with a number of faults:
If DF077 is present with fault DF232 Driver's seat belt buckle sensor circuit and
DF183 Driver's front buckle pretensioner circuit, start fault finding by checking the
8-track R335 connector under the driver's seat.
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 command VP006 Lock computer.
Switch off the ignition.
Check the condition of the 8-track R335 connector under the driver's 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 R335 connector under the driver's seat.
Switch on the ignition again.
Read the fault in the AIRBAG / PRETENSIONER field.
AFTER REPAIRReconnect the computer and the ignition module for the driver's front side chest-level
airbag module
then switch on the ignition again. Clear the computer fault memory using command
RZ001 "Fault memory". Switch the ignition off and then on again.
Repeat the check using the diagnostic tool and, if there are no faults (ignore DF034
Computer locked), unlock the computer using command VP007 Unlock computer.
When replacing the airbag module, do not forget to reconnect the earth on the new
module.

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
