Fault finding - Function88C
By default, when the key is in the inhibition position, the following protections and signals are inhibited in the event of
a crash:
–Passenger front air bag.
–Passenger chest-level airbag, if fitted.
The passenger front airbag and passenger chest-level airbag are inhibited when the locking switch is
positioned on OFF or when DF028 "PASSENGER AIRBAG STATUS INDICATOR LIGHT CIRCUIT" or DF193
"PASSENGER AIRBAG LOCKING STATUS CHANGE" is present in the computer memory.
–Seat belt locking monitoring:
This function is carried out by the instrument panel (seat belt reminder indicator light and buzzer). The MRSZ
computer only sends the driver's seat belt buckle sensor status.
An instrument panel warning light indicates that the seat belt is not being worn by the driver and a beep sounds as a
reminder when the vehicle speed exceeds 12 mph (20 km/h).
–Monitoring the information displayed on the instrument panel:
The instrument panel controls the correct operation of the "Airbag fault" and "Airbag OFF" warning lights and
informs the airbag computer, via the multiplex network, of any possible malfunctions in the warning light circuits.

Fault finding - Replacement of components
REPLACING A SYSTEM COMPONENT
Disconnect the battery before removing and refitting any pyrotechnic component (airbag module,
pretensioner or seat belt retractor).
The computer must always be locked before any operation on a system component.
REPLACING THE AIRBAG COMPUTER
BEFORE REPLACING THE COMPUTER IT IS ESSENTIAL THAT YOU CONTACT THE TECHLINE.
To ensure that the returned computer's fault can be analysed, do not use command RZ001 "FAULT
MEMORY" when DF001 "COMPUTER" is present or stored.
The airbag computers are sold in locked mode to avoid all risk of accidental triggering (all trigger lines are inhibited).
The "locked" mode is indicated when the airbag fault warning light on the instrument panel lights up.
Follow this procedure to replace an airbag computer:
–check that the ignition is switched off,
–replace the computer,
–modify the computer configuration if necessary,
–enter the VIN into the computer with the diagnostic tool using command VP010 "WRITE VIN",
–switch off the ignition,
–carry out a check using the diagnostic tool,
–unlock the computer with command VP007 "UNLOCK COMPUTER", only if there are no faults indicated by the
diagnostic tool and check that the indicator light has gone out.

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''.
