This bornier is connected instead of the computer,
fitted with a single 30-track connector.
It enables all the ignition lines to be checked by
means of the XRBAG, the supply voltage of the
computer to be measured, and the airbag war-
ning light on the instrument panel to be illumina-
ted.
Terminals also enable the continuity checks to be
carried out on the diagnostic lines, the warning
light lines and the feed to the computer (see sec-
tion on fault finding).
XRBAG TEST UNIT (Elé. 1288)
96833G
This unit is a tool specifically designed for testing
and fault finding on airbag devices and seat belt
pretensioners.
It enables electrical measurements to be carried
out on the different lines in the systems.
(See "fault finding" section).
IMPORTANT: It is not permitted to carry out mea-
surements on these systems with an ohmmeter or
any other electrical measuring instrument: there
is a risk of triggering due to the operating current
of the instrument.

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.

DRIVER’S AIRBAG
DESCRIPTION
It is located in the steering wheel cushion.
It comprises:
- an inflatable cushion,
- a pyrotechnic gas generator and ignition
module.
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.
