SEAT BELTS
When the pretensioners are triggered the front
seat belt or belts must be systematically replaced
if they were attached during the pretensioning (if
there is any doubt about wearing the belt it must
be replaced). The physical stresses exerted on the
catch are transmitted to the inertia reel and may
damage its mechanism.
REMOVAL
IMPORTANT: The pyrotechnic systems (pretensio-
ners) must not be handled near a heat source or
flame; there is a risk of triggering.
Remove:
- the pretensioner connector under the front
seat,
- the pretensioner assembly, after removing its
protective trim.
IMPORTANT : before scrapping a non-triggered
pretensioner it
MUST be destroyed in accordance
with the method for destruction (except for parts
returned under warranty) (see section
"Destruction procedure").
REFITTING
Ensure that the wiring is correctly routed and the
wiring mounting points are correct under the
seat.
NOTE: For vehicles with airbag(s), the computer
may be locked using the XR25 and command
G80* (ISO selector on S8 code D49) during the
operation.
When this function is active, all the trigger lines
are inhibited, the airbag warning light on the ins-
trument panel and bargraph 14 LH on the XR25 il-
luminate (new computers are supplied in this
condition).
After the operation, carry out a check using the
XR25. If everything is correct, unlock the compu-
ter using command G81*.
IMPORTANT :
For vehicles with pretensioners only (without
fault finding on the XR25) :
• Before reconnecting the pretensioners (connec-
tor under the seat), check the condition of the
equipment using the XRBAG (Elé. 1288) on the
two pretensioners (see fault finding section),
• On the pretensioners side, ensure the connec-
tor (C) is properly connected (clipped fully
home).
For vehicles with pretensioners and airbag :
• Test using the XR25 after reconnecting the
connectors. Unlock the computer using
command G81* if everything is correct.
• On the pretensioners side, ensure the connec-
tor (C) is properly connected (clipped fully
home).
REMINDER: if the pretensioners have been trig-
gered their computer
MUST be replaced.

STEERING WHEEL AIRBAG AND ROTARY SWITCH
REMOVAL
IMPORTANT: The pyrotechnic systems (airbag
and pretensioners) must not be handled near a
heat source or flame; there is a risk of triggering.
IMPORTANT : If the steering wheel is removed,
the airbag connector
MUST be disconnected (D) .
The airbag connector short circuits when it is dis-
connected to prevent incorrect triggering.

If it is being replaced, the new part is supplied rea-
dy centred by an adhesive label which will tear off
as soon as the steering wheel is turned for the first
time (fit with the wheels straight).
REFITTING
Ensure the wheels are still straight.
Ensure the rotary switch under the steering wheel
is still immobilised before refitting.
If this is not the case, follow the centring method
described below:
- rotate the upper section of the rotary switch
anti-clockwise. The approach to the extreme
position, shown below, is indicated by a cer-
tain stiffness (do not force).
SPECIAL NOTES FOR THE ROTARY SWITCH
UNDERNEATH THE STEERING WHEEL
This makes the electrical connection between the
steering column and the steering wheel.
It consists of a strip of conductor tracks (airbag)
whose length is designed to guarantee 2.5 stee-
ring wheel turns (steering lock plus safety margin)
on each side.
REMOVAL
Before removing the rotary switch its position
must be noted:
• by ensuring that the wheels are straight on re-
moval so that the track may be positioned in
the centre,
• by immobilising the rotary switch rotor using
adhesive tape.
- then lightly rotate the upper section of the part
clockwise and check that the rotary switch is ac-
tually in the position shown below.

IMPORTANT :
When everything has been refitted:
• Carry out a check using the XR25 to ensure that
there is no fault in the system.
• Unlock the computer with command G81* .
• Check that the airbag warning light illuminates
for 3 seconds after the ignition is switched on
then extinguishes and remains extinguished.
If the warning light does not operate as described
above, refer to the "Fault finding" section and
check the system using the XRBAG (Elé. 1288) or
XR25.
IMPORTANT:
If these procedures are not correctly observed the
systems may not operate correctly or may be
accidentally triggered.

- again rotate the part in the clockwise direction
by making two complete turns, and after this
operation make sure that the rotary switch is
actually in the position previously described.
Refit the steering wheel and replace the pre-
bonded bolt, ensuring its correct tightening tor-
que (4.5 daN.m).
Reconnect the airbag cushion and secure it to the
steering wheel, tightening torque (0.5 daNm).
SPECIAL CASES
Where work is being done involving removal of
the steering, engine, transmission, etc., requiring
uncoupling of the rack and steering column:
→ the steering wheel must be immobilised using a
"steering wheel locking" tool.
IMPORTANT: to avoid destroying the rotary
switch under the steering wheel it is IMPORTANT
to maintain the fixed position of the steering
wheel throughout the operation.
If there is any doubt about its correct centring the
steering wheel must be removed so that the cen-
tring method described above can be applied.
REMINDER: in this case, only qualified personnel
who have received the correct training must work
on the airbag.

REMOVAL
The dashboard must be removed to remove the
passenger airbag module (see "Removing -
refitting the dashboard", section 83).
Then remove the airbag module (four nuts).
IMPORTANT : When the passenger airbag module
is triggered, the damage to its mountings means
that the dashboard must be renewed.
IMPORTANT : before scrapping a non-triggered
airbag it
MUST be destroyed in accordance with
the method for destruction of the driver’s airbag
(see section "Destruction procedure": destruction
of part removed from the vehicle).
Accessibility of passenger airbag ignition mo-
dules for fault finding
The dashboard must be removed to reach the pas-
senger airbag ignition modules.
IMPORTANT : The ignition module must be
checked using the XRBAG as indicated in the
"Fault finding" section.

REFITTING
IMPORTANT: The following safety advice MUST
be followed when refitting or replacing a passen-
ger airbag module. If these instructions are not
followed the system may not operate normally
and could even cause a risk for the vehicle occu-
pants.
IMPORTANT :
Refitting is the reverse of removal. The tightening
torque of the 4 module mounting bolts
(0.6 daN.m)
MUST be observed.
• Renew the "System tamperproof " label with a
blue After Sales label sold in kit Part Number
77 01 205 356 for all types.
• Remember to remove all foreign bodies (bolts,
clips) when fitting the airbag.
IMPORTANT :
Before reconnecting the passenger airbag module
and refitting the dashboard, the system wiring
must be checked.
Fit a dummy ignition module (Elé. 1288) to the
passenger airbag module connector.
Connect the 30 track adapter of the XRBAG to the
orange 30 track connector on the computer
wiring.
After supplying power to the XRBAG (battery),
connect the white 2 track measuring connector to
wiring (C) of the adapter, and the measurement
should be between 1.8 and 4.6 Ω.
If the measurements are correct:
• Disconnect the dummy ignition module.
• Connect the wiring to the passenger airbag
ignition module (by offering up the dashboard)
and connect the white 2 track measuring
connector of the XRBAG once more to wiring
(C) of the adapter, and the measurement
should be between 1.8 and 4.6 Ω.
If the measurements are correct:
• Refit the dashboard.
• Use the XR25 to check no faults are present in
the system.
• Unlock the computer using command G81*.
• Check that the airbag warning light illuminates
for 3 seconds when the ignition is switched on
then extinguishes and remains extinguished.
If the warning light does not operate as described
above, or the values measured are incorrect, refer
to the "Fault finding" section.
