procedures are followed the airbags can be safely
deployed & then all component parts can be
properly recycled.
DISPOSAL PROCEDURE
NOTE
The disposal of AIR BAG module assembly
shall be done in an area with adequate
ventilation.
A person handling any restraints module
assembly shall have to wear ESD (electro-static
discharge) straps to reduce any risk of
inadvertent deployment.
1. Follow the guidelines for removal of AIR BAG
module assembly as specified in workshop
manual. If the module assembly is found
defective before fitment on the vehicle, go to
step 2
.
2. Wear adequate ear protection device (
ear
plugs)
, safety goggles and safety hand gloves.
3. Connect the specified connector to the
restraints module assembly, with a pig-tail.
4. Clamp the restraints module assembly in a
shop bench vise
(or equivalent clamping
mechanism)
. The clamping force should be
adequate.
5. refer the following methods for clamping the
different air bag modules on bench vise

assembly. The battery voltage shall be in the
range of 8-16V.
7. Connect one core of the electrical wire to the
positive (+ve) battery terminal.
