GENERAL INFORMATION

Airbag and pretensioner deployment
Deployment procedures and precautions as detailed
in this manual should be strictly adhered to. Only
personnel who have undergone the appropriate
training should undertake deployment of airbag and
pretensioner modules. The following precautions
must be complied with:
lOnly use deployment equipment approved for
the intended purpose.
lBefore beginning deployment procedure,
ensure deployment tool functions properly by
performing the self test procedure detailed in
SRS section of this manual.
lDeployment of airbag/ pretensioner modules
should be performed in a well ventilated area
which has been designated for the purpose.
lEnsure airbag/pretensioner modules are not
damaged or ruptured before attempting to
deploy.
lNotify the relevant authorities of intention to
deploy airbag and pretensioner units.
lWhen deploying airbag pretensioner units,
ensure that all personnel are at least 15 metres
(45 feet) away from the deployment zone.
lEnsure deployment tool is connected correctly,
in compliance with the instructions detailed in
the SRS section of this manual. In particular,
ensure deployment tool is NOT connected to
battery supply before connecting to airbag
module connector.
lWhen deploying seat belt pretensioners, ensure
pretensioner unit is secured correctly to the
seat.
lWhen removing deployed airbag modules and
pretensioner units, wear protective clothing.
Use gloves and seal deployed units in a plastic
bag.
lFollowing deployment of any component of the
SRS system within the vehicle, all SRS
components must be replaced. DO NOT re-use
or salvage any parts of the SRS system.
lDo not lean over airbag module when
connecting deployment equipment.
If a vehicle is to be scrapped, undeployed airbag
modules and pretensioner units must be manually
deployed. In this case airbags can be deployed in the
vehicle; before deployment, ensure the airbag
module is secure within its correct mounting position.
Deployment of the driver's airbag in the vehicle may
damage the steering wheel; if the vehicle is not being
scrapped, deploy the module outside of the vehicle.
WARNING: During deployment parts of the
airbag module become hot enough to burn you.
Wait 30 minutes after deployment before
touching the airbag module.
SRS Component Replacement Policy
The following information details the policy for
replacement of SRS components; either as a result
of a vehicle accident or as a result of vehicle age.
Impacts which do not deploy the airbags or pre-
tensioners
Check for structural damage in the area of the
impact, paying particular attention to bumper
armatures, longitudinals, crash cans and bracketry.
Impacts which deploy the airbags or pre-
tensioners
The replacement and inspection policy is dependent
on the type and severity of of the crash condition.
The following guidelines are the minimum that
should be exercised as a result of the deployment of
specific SRS components.
If the front airbags or seat belt pre-tensioners are
deployed, the following parts must be replaced:
lSRS DCU.
lDriver airbag module
lPassenger airbag module
lFront seat belt buckle pre-tensioners
lRotary coupler
lDriver's seat belt retractor
lFlyleads (where applicable) connecting airbags
and seat belt pre-tensioners to SRS harness
In addition, the following should be inspected for
damage and replaced as necessary:
lFront passenger's seat belt retractor (webbing,
tongue latching, 'D' loop, body anchorage point)
lRear seat belt buckles (webbing, buckle covers,
body anchorage and tongue latching function)
lFascia moulding adjacent to passenger airbag
module
lSteering wheel (if damage is evident)
lFront seat frames and head restraints (if there is
evidence of damage to the seat frame or
cushion pan)
lSteering column (if adjustment is lost or there
are signs of collapse)
lThird row seats, seat belts and head restraints
(where fitted). Check third row seat latching
mechanism operates correctly.
Periodic replacement of SRS components
The performance of the propellants within airbags
and pre-tensioners will deteriorate over a period of
time. As a result, it is essential that the airbags are
replaced after 10 years and seat belt pre-tensioners
are replaced after 15 years in order to maintain
occupant safety.
