Operations on system components
At the end of every operation on the system, it must be
checked using Modus, I.W.T. or other diagnostic tools.
During assembly, the air bag components are labelled with a
sticker with a removable part stating the date of installation
of the system and components. The removable part is
detached and the information on it is filed together with the
system check report supplied by Modus, by the workshop that
installed the components.
After 10 years from installation, unless the components are
replaced before that time, a new air bag system (cable and
components) should be installed. As mentioned previously,
the data concerning the components and the date of system
installation are to be filed.
Removing and scrapping an activated air bag
module and pretensioner from a vehicle
Always wear gloves and safety goggles for handling an
activated air bag or pretensioner. Wash the hands and
exposed skin immediately with neutral soap and water after
handling the components of an air bag module or
pretensioner. In the case of exposure to secondary products,
immediately rinse the eyes with running water. The failure to
comply with these instructions may result in injury.
To remove and scrap an already activated air bag module and
pretensioner:
1. Follow the instructions given in this manual for removing
activated air bag module and pretensioners.
2. Disconnect the air bag module and pretensioner
mechanical fastenings.
3. Disconnect the component connector from the air bag
harness.
4. Place the air bag module and pretensioner in a special
sealed polythene bag.
5. Send to the authorised collection/disposal centre.
6. Dispose of, recycle or scrap deployed air bag modules
and pretensioners in the appropriate manner.
The residues left by combustion of the propellant require
some consideration. They are mostly concentrated in the
generator body or in small quantities in the bag. These
residues may contain copper or chloride (e.g. potassium
chloride). If the propellant is based on sodium azide or
potassium nitrate, the combustion residues are highly alkaline
and corrosive.
Always wear appropriate protection for the
eyes and skin. Deployed air bags should always be stored in
dry, suitably ventilated places.
Removing or scrapping an air bag module that
has not been deployed from a reparable
vehicle
If the connector is cut or removed from the air bag unit, the
safety device is disabled and this could cause unforeseen
activation with serious consequences for the physical
integrity of people.
Air bag systems have a reserve power unit in the control unit.
This must be deactivated disconnecting the two battery
terminals and waiting for at least 10 minutes before doing any
work on any components of the air bag.
When handling an air bag module, always keep the bag and
outer cover away from the body. When positioning an active
air bag on a bench or other surface, always place the bag and
its cover upwards, not on the resting surface and away from
people. Never put any object near an active air bag as it
would become a bullet in the event of deployment.
Active, damaged air bag modules and pretensioners (e.g.
breakage of the electrical connection) must be kept away
from corrosive or oxidising substances. The failure to comply
with these instructions may cause fire, and/or serious harm
to persons.
!
Do not cut cables or tamper with the connector
between the vehicle harness and the air bag module.
The connector contains a safety circuit.
!
Always keep active, undamaged, air bag modules and
pretensioners in a cool, dry, locked and safe place.
Do not expose to naked flames or temperatures
above 150 ºC. Do not cut, drill, braze weld an air bag
module or its components with electric current.
Never expose an air bag module or pretensioner to
electric currents. The failure to comply with these
instructions may damage the unit, cause fire, cause
unforeseen deployment and serious harm to
persons.
The air bag modules and pretensioners have an
energy reserve. This decive gives the electric pulse
needed to deploy the bag if the battery or cables are
damaged during the crash before the sensor activates
the gas generator. NOTE
