Airbag module - drivers - deployment
$% 76.74.99
These guidelines are written to aid authorised
personnel to carry out the safe disposal of airbag
modules when removed from the vehicle.
If a vehicle is to be scrapped and contains an
undeployed airbag module, the module must be
manually deployed. This operation should only
be carried out using the following recommended
manual deployment procedure. Before
deployment is started the deployment tool self
test procedure should be carried out.
WARNING: Only use approved deployment
equipment, and only deploy SRS components in
a well ventilated designated area. Ensure SRS
components are not damaged or ruptured before
deployment. Notify the relevant authorities.
CAUTION: Deployment in the vehicle will damage
the steering wheel. If the vehicle is not being
scrapped, deploy the module away from the
vehicle in accordance with the correct
procedure.
