IMPORTANT : before removing the air bag cus-
hion, lock the computer using the fault finding
tool.
When this operation is activated, all the trigge-
ring lines are inhibited, the air bag warning light
on the instrument panel is illuminated
Removal
IMPORTANT:The pyrotechnic systems (pretensio-
ners or air bags) must not be handled when near a
heat source or a flame because there is a risk that
the system will be triggered.
IMPORTANT : When removing the steering wheel,
the air bag connector must be disconnected (D)
(see below).
The air bag is fitted with a connector which short
circuits when it is disconnected to avoid incorrect
triggering .
Remove the air bag cushion by its two torx bolts
located behind the steering wheel and disconnect
its connector (D).

IMPORTANT : before scrapping an untriggered air
bag module, it
MUST be destroyed in accordance
with the method described in the "Destruction
Procedure" section
Refitting
Reconnect the air bag cushion and mount it to
the steering wheel (tightening torque : 0.5
daN.m).
NOTE :press the connector in firmly on the cus-
hion side (D) (strong clipping system).
IMPORTANT : after refitting everything,carry out
a check using the fault finding tool .
Unlock the computer if everything is correct,
otherwise see the"Fault Finding" section.
REMINDER: the computer in these vehicles can wi-
thstand several triggerings. Therefore, it does not
have to be replaced after every triggering of the
air bag(s) or pretensioners (see "Computer" sec-
tion).

ROTARY SWITCH
The rotary switch ensures the electrical connec-
tion between the steering column and the stee-
ring wheel.
It consists of a strip with two conducting tracks
(air bag) of which the length is long enough to al-
low 2.5 turns of the steering wheel (full lock plus
safety) for each side.

Remove :
- the air bag cushion by its two torx bolts located
behind the steering wheel and disconnect its
connector (D).
- the steering wheel bolt,
- the steering wheel after positioning the wheels
straight,
- the half cowlings (three bolts).
Disconnect the stalks (windscreen wipers and
lights) and the rotary switch connector.
Before removing the assembly, the rotary switch
position must be noted:
- by ensuring that the wheels are straight during
removal in order to position the length of the
strip in the centre ,
- by checking that the mark "0" is correctly posi-
tioned opposite the fixed index (E).

It consists of:
- an inflatable cushion,
- a pyrotechnic gas generator and ignition mo-
dule.

The air bag module components cannot be sepa-
rated.
NOTE : this system is operational when the igni-
tion has been switched on.
Accessing the ignition module
To access the ignition module of the passenger air
bag module, the upper part of the dashboard
must be removed.
Important, if the vehicle is fitted with a red
connector with lugs, see the recommendations on
the following page.
REMINDER: the ignition module check for the mo-
dule must be carried out using the
XRBAG as des-
cribed in the "Fault Finding" section.Removal
IMPORTANT:The pyrotechnic systems (pretensio-
ners or air bags) must not be handled when near a
heat source or a flame because there is a risk that
the system will be triggered.
IMPORTANT : Before removing a passenger air
bag module, lock the computer using the fault
finding tool.
When this operation is activated, all of the trigge-
ring lines are inhibited, the air bag warning light
on the instrument panel is illuminated.
To remove the passenger air bag module the up-
per part of the dashboard must be removed.
Remove:
- the windscreen pillar trim sections,
- the half cowlings under the steering wheel
- the mounting bolts on the upper part of the
dashboard and release it (for more details see
"section 83 in MR 337").
Disconnect the ignition module.
The passenger air bag module is mounted by six
bolts.

IMPORTANT : In the event that the passenger air
bag module should be triggered, the deforma-
tion of the mountings (microcracks) means the
metal dashboard support beam must be replaced.

Reconnect the computer and the air bag cushion ignition module, then switch on
the ignition. Erase the computer memory, then switch off the ignition. Carry out a
check again using the fault finding tool and, in the absence of a fault, unlock the
computer. Destroy the air bag if there has been a replacement (tool ELE. 1287).

Lock the computer using the command on the fault finding tool.
Switch off the ignition and remove the 2 steering wheel boss mounting bolts.
Check that it is connected correctly.
Disconnect the steering wheel boss and attach a dummy ignition module to the ignition module
connector. Switch on the ignition and carry out a check using the fault finding tool.
Replace the air bag cushion if the fault has been memorised (fault no longer declared present).
The XRBAG must be used to measure resistance at point C2 of the driver’s air bag circuit.
If the value obtained is not correct, replace the rotary switch under the steering wheel.
Reconnect the rotary switch under the steering wheel, disconnect the computer connector and fit the 30
track B40 adaptor.
The XRBAG must be used to measure resistance on adaptor cable A .
If the value obtained is not correct,
check the connections on the 30 track connector (tracks 10 and 11)
and replace the wiring if necessary.
If there is no evidence of a fault after these checks have been carried out, check on the air bag computer
base for the 5 shunt opening pins for the 30 track connector.
Check the condition of the computer connections
Check the condition of the 30 track connector (locking system, ...).
With the ignition switched off, disconnect then reconnect the rotary switch connector under the steering
wheel.
