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.
