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
