DRIVER'S FRONT AIRBAG CIRCUIT
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 configuration reading LC028
Driver's front airbag, then modify it if it is inconsistent using the configuration CF209
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. 1837- 5) and dummy module (part no. Elé. 1835
yellow).
Use the W iring Diagrams Technical Note, New TWINGO.
Lock the trigger lines using command VP006 Lock computer.
Switch off the ignition.
Remove the driver's airbag, component code 899 (see MR 411, Mechanical, 88C, Airbag and pretensioners,
Driver's front airbag: Removal - Refitting).
Check the condition of the driver's front airbag connector (see Wiring Diagram Technical Note, New Twingo,
Component code 899 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.
Fit the dummy module (part no. Elé. 1835 yellow) on the driver's front airbag connector, component code 899.
Switch on the ignition again.
Read the fault in the AIRBAG / PRETENSIONER field.
If the fault has become "Stored":
Replace the driver's front airbag component code 899.
If the fault remains "Present":
Switch off the ignition.
Check the condition of the rotary switch connector, component code 689 (see Wiring Diagram Technical Note,
New Twingo, Component code 689, Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair and MR 411, Mechanical, 84A, Controls-Signals, Steering column switch assembly: 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.
Position the dummy module (part no. Elé. 1837 - 5) on the rotary switch connector component code 689.
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 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, see MR 411, Mechanical, 88C, Airbag and pretensioners, Airbag
computer: Removal - Refitting 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.
Faulty wiring between the airbag computer component code 756 and the rotary switch component code 689.
Check the insulation (+ 12 V, to earth and between the 2 lines) and the continuity of the following
connections:
–Connection code 60AM between components 756 and 689,
–Connection code 60AN between components 756 and 689.
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 rotary switch component code 689 (see MR 411, Mechanical, 84A, Controls - Signals, Steering
column switch assembly: 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 the check using the diagnostic tool and, if there are no faults (ignore DF034
Computer locked), unlock the computer using command VP007 Unlock computer.
