Refitting
To refit it, position the sensor using its lug and
mount it to the vehicle before reconnecting the
connector(tightening torque : 0.8 daN.m).
After connecting its connector, carry out a check
using the fault finding tool.
Unlock the computer if everything is correct,
otherwise see the"Fault Finding" section.

OPERATION ON THE TRIGGERING LINES
In the event of a fault noted on one of these lines,
the component must be replaced and not repai-
red.
This safety device can not tolerate any conventio-
nal repair operation on the wiring or connectors.
The air bag and pretensioner triggering lines are
integrated in the passenger compartment wiring
harness. In order to make repairs easier, the re-
placement method consists of cutting the two ex-
tremities of the faulty wiring and making the
new wiring follow the same route along the pas-
senger compartment wiring harness.
IMPORTANT: when refitting the new wiring, en-
sure that it is not subject to damage and that the
original cleanliness has been respected.
Special case : the connector with lugs
A series of vehicles are fitted with a red connector
with lugs(A) passenger air bag module side.
16008R
To disconnect it, carefully use a small screwdriver
as a lever , so as not to damage the lugs .
In the event of the lugs breaking, replace the
connector using the kit part number : 77 01 206
210 using the following method.

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).
14036R1
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).

Refitting
Ensure that the wheels are still straight.
Check that the mark "0" on the rotary switch is
correctly positioned opposite the fixed index (E).
IMPORTANT: If these procedures are not correctly
observed the systems may not operate correctly
or may be accidentally triggered.
Engage the assembly on the steering column and
connect the different connectors.
Carry out the rest of the refitting and only lock
bolt (C) once the two half cowlings have been re-
fitted, to position the stalks in alignment with the
instrument panel and the dashboard.
This operation is made easier by a cut-out giving
access to the bolt (C) in the lower half cowling.
Change the steering wheel bolt after each remo-
val (pre-bonded bolt) and observe its tightening
torque (4.5 daN.m).
Reconnect the air bag cushion and fix 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
• To avoid damaging the rotary switch under the
steering wheel, the fixed position of the stee-
ring wheel must be maintained during the ope-
ration.
• If there is any doubt about whether the stee-
ring wheel is correctly centred, it must be remo-
ved for verification.
• In the event of an operation to remove the
steering, engine, transmission components etc,
where the steering rack and steering column
have to be separated, the steering wheel must
be immobilised using a "steering wheel
locking" tool.
IMPORTANT : after refitting every thing, carry out
a check using the fault finding tool.
Unlock the computer if everything is correct,
otherwise see the"Fault Finding" section.
PASSENGER AIR BAG MODULE
Description
It is mounted in the dashboard opposite the front
passenger.

Refitting
IMPORTANT: the safety notes which must be fol-
lowed to refit or replace the passenger air bag
module must be observed .
If these procedures are not correctly observed the
systems may not operate correctly or may be acci-
dentally triggered, presenting a danger to the oc-
cupants of the vehicle.
Refitting is the opposite of removal
IMPORTANT: a 2nd generation passenger air bag
module must not be fitted to a vehicle fitted with
a 1
stgeneration computer (see the table on
pages 2 and 3).
Observe part numbers mentioned in the spare
parts catalogue, referring to vehicle equipment.
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).
IMPORTANT
• No foreign body (bolt,clip...) must be forgotten
when refitting the air bag module.
• Reconnect the passenger air bag module and
secure it (tightening torque : 0.6 daN.m).
• Press the connector in firmly on the module
side (strong clipping system).
• Attach a blue adhesive sticker " after sales sys-
tem tamperproof label" sold under part num-
ber : 77 01 205 356 on the air bag module
connector.
• 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.
SIDE AIR BAG MODULE
Description
It is fitted into the seatback of the front seats on
the door side.
It comprises :
- an inflatable bag,
- a pyrotechnic gas generator and ignition
module.
These components cannot be separated.
15132R
In order to work the inflatable bag tears through
the module cover, the foam and the seat trim.
NOTE: this system is operational after the ignition
has been switched on.
IMPORTANT:
The pyrotechnic systems (pretensioners 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.
No measurements may be made on these systems
using an ohmmeter or any other electrical measu-
ring equipment: the system may be triggered due
to the operating current of the measuring equip-
ment.
