Several types of unit may be found:
- one computer for pretensioners only.
- one computer for pretensioners and airbag(s).
Depending on function, these computers have:
- an electromagnetic safety sensor,
- a decelerometer for the airbags
- an ignition circuit for the different pyrote-
chnic systems,
- a power reserve,
- a diagnostic and detected fault storage circuit
(except pretensioner only),
- a control circuit for the warning light on the
instrument panel (except pretensioner only),
- a K - L communication interface via the dia-
gnostic socket (except pretensioner only).
IMPORTANT
Before removing the computer:
Vehicle with pretensioners only (no air-bag) :
- Switch off the ignition.
- Remove the feed fuse (see fuse allocation) and
wait for 5 minutes for the reserve capacity to
discharge.
- Disconnect the computer connector to avoid
any risk of triggering.
- Ensure no-one is in the passenger compartment
during the complete operation on the compu-
ter.

IMPORTANT:
• When carrying out an operation under the ve-
hicle (exhaust, bodywork, etc.), do not use a
hammer or transmit impacts to the floor wi-
thout having removed the pretensioner fuse
and waited 5 minutes for the reserve capacity
to discharge (see section "Fuse allocation", in
the "Wiring diagram" technical note) or for ve-
hicles with the airbag function, wait for 2 se-
conds for the unit to discharge automatically.
• When fitting an electrical accessory in After
Sales, (speaker, alarm unit or any equipment
which may create a magnetic field), it must not
be located near the airbag and pretensioner
computer.CONNECTION

WARNING LIGHT ON THE DASHBOARD
This warning light controls the pretensioners and
airbags, except for vehicles fitted with pretensio-
ners only.
It should illuminate for a few seconds when the
ignition is switched on, then extinguish (and
remain extinguished). If it does not illuminate
when the ignition is switched on, or illuminates
when the vehicle is being driven, there is a fault in
the system (see fault finding section).
IMPORTANT : the systems MUST be checked by
means of the
XRBAG, following:
- an accident which has not given rise to
triggering,
- theft or attempted theft of the vehicle,
- before the sale of a used vehicle.
These systems are not triggered in the case of:
- a lateral impact,
- a rear impact.
When it is triggered the pyrotechnic gas
generator produces an explosion combined with
light smoke.
NOTE : With pretensioners only,the computer has
a single sensor (electromechanical).
OPERATIONS ON THE TRIGGER LINES
If a fault is noted on one of these lines, the
component must be renewed and not repaired.
This safety equipment cannot be subjected to any
conventional wiring or connector repair opera-
tions.
The airbag trigger wiring is integrated into the
passenger compartment wiring loom . To make
replacement easier, cut the two ends of the faulty
wiring and run the new wiring along the same
routing, alongside the passenger compartment
wiring loom.
IMPORTANT : When fitting the new wiring, en-
sure it is not in danger of being cut or rubbed and
that the original wiring cleanliness is respected.
NOTE : The trigger lines are supplied by the Parts
Department in a kit containing both airbag and
pretensioner wiring.
OPERATION WITH AIRBAG(S) AND PRETENSIONER
EQUIPMENT
When the ignition is switched on, the
warning light illuminates for a few
seconds then extinguishes.
This computer is then on standby and notes dece-
lerations of the vehicle using the signal measured
by the integral decelerometer.
When a frontal impact of sufficient strength oc-
curs it triggers the simultaneous ignition of the
pyrotechnic generators of the two seat belt pre-
tensioners after receiving confirmation of detec-
tion of an impact by the electromechanical safety
sensor.
Under the action of the gases generated by the
system, a piston is displaced in its cylinder,
carrying with it a cable connected to the
corresponding central catch, thus enabling the
seat belt to be retracted (see pretensioner
section).
If the frontal impact is greater than this, the dece-
lerometer triggers the ignition of the pyrotechnic
gas generators which inflate the driver and pas-
senger airbags once the impact has been valida-
ted by the electromechanical safety sensor.

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.

These components cannot be separated.
96310-1S
NOTE : when the airbag inflates, the steering
wheel cover is torn.Warning light on the instrument panel
shows the correct operation of the driver’s airbag,
the passenger’s airbag and the pretensioners (de-
pending on equipment).
NOTE : this system is operational after the ignition
has been turned on. A vehicle fitted with a driver’s
airbag will be identified by a label in the bottom
corner of the windscreen on the driver’s side, and
by the word "Airbag" in the centre of the steering
wheel.
Each time the windscreen is replaced, remember
to fit the labels showing that the vehicle is fitted
with airbags.These labels are available in a kit Part
Number : 77 01 205 442.
REMINDER : The computer must be replaced after
the airbag has been triggered. Certain compo-
nents will lose their nominal characteristics after
the trigger energy has passed through them.

- 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.
