Airbag and pretensioners: Precautions for the repair
Equipment required
Diagnostic tool
I - PRECAUTIONS FOR REPAIR
IMPORTANT
All operations on airbag and pretensioner systems
must be carried out by qualified trained personnel.
The airbags have a pyrotechnic gas generator, with
an ignition module and bag which must not be sep-
arated.
The pretensioners have a pyrotechnic gas genera-
tor and an igniter which must, under no circum-
stances, be separated.
IMPORTANT
Never handle the pyrotechnic systems (pretension-
ers or airbags) near to a source of heat or naked
flame - they may be triggered.
IMPORTANT
To prevent any accidental triggering whilst working
on or near a pyrotechnic component (airbags or
pretensioners), lock the airbag computer using the
Diagnostic tool.
When this function is activated, all the trigger lines
are inhibited and the airbag warning light on the
instrument panel lights up continuously (ignition
on).
(see Fault finding - Replacement of compo-
nents) (88C, Airbag and pretensioners).
When working underneath the vehicle (on the body-
work, sill panel, etc.) or for certain operations involving
removal or refitting of seat trims, it is essential to lock
the airbag computer using the Diagnostic tool and to
disconnect the battery (see 80A, Battery, Battery: Re-
moval - Refitting, page 80A-2) .
IMPORTANT
To prevent the pyrotechnic components from being
permanently deactivated or triggered (airbags or
pretensioners), check the airbag computer using
the Diagnostic tool.
The pyrotechnic systems (pretensioners and airbags)
must be checked using the Diagnostic tool :
- after an accident,
- after theft or attempted theft of the vehicle,
- before selling a used vehicle.
II - TRIGGERING OF THE SAFETY SYSTEMS
IMPORTANT
In order to prevent interference with the deployment
of the airbags:
- do not fit a cover to the front seats,
- do not place objects in the area of deployment.
After detection of an impact, the airbag computer locks
definitively and the « airbag fault » warning light is illu-
minated on the instrument panel. The airbag computer
and the side impact sensors must always be replaced.
IMPORTANT
To eliminate the risk of any accident, do not reuse
pyrotechnic components.
It is essential to destroy pretensioners or airbags
before scrapping a vehicle or a part only (see Air-
bags and pretensioners: Recycling - Destruc-
tion) .
III - DURABILITY OF THE PYROTECHNIC
COMPONENTS
The precautions which recommended that pyrotechnic
components (airbags and pretensioners) were re-
placed 10 years after the registration of the vehicle
have now been lifted.
Pyrotechnic components (airbags and pretensioners)
do not therefore require any maintenance.
