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 the computer configuration using the configuration reading LC027
Passenger's front airbag, then modify it if it is inconsistent using the configuration
CF210 Driver's front airbag.
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".
Special note:
Use dummy module (Part no. Elé.1835 yellow).
Use the W iring Diagrams Technical Note, New TWINGO.
Lock the trigger lines using the command VP006 Lock computer.
Switch off the ignition.
Remove the passenger's airbag, component code 861 (see MR 411, Mechanical, 88C, Airbag and
pretensioners, Passenger's front airbag: Removal - Refitting).
Check the condition of the passenger's front airbag connector, component code 861 (see Wiring Diagram
Technical Note, New Twingo, Component code 861 and Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair).
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 airbag connector component
code 861.
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 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.

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, Technical Note 6015A, Repairing electrical wiring, Wiring:
Precautions for repair and MR 411, Mechanical, 88C, Airbag and pretensioners, Airbag computer:
Removal - Refitting).
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 passenger front airbag component
code 861.
Check the insulation (+ 12 V, to earth and between the 2 lines) and the continuity of the following
connections:
–Connection code 60H between components 756 and 861,
–Connection code 60K between components 756 and 861.
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":
Replace the passenger's front airbag component code 861 (see MR 411, Mechanical, 88C, Airbag and
pretensioners, Passenger's front airbag: Removal - Refitting).
If the fault is still present, contact the Techline.
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''.
