Removing airbag need an extreme caution, this is very explosive stuff it could knock you down big time. Aside from removing your battery you will need also to find out which wire color for the steering airbag, in that case you can avoid common mistakes. Most wire run under your dash board that goes to your steering wheel. You need also a breaker bar to remove your steering wheel upon completion of removing airbag. Again, its not an easy task, so be carefull.
the corona procedure should be enough. most airbags are triggered by a primer na pinapaputok with current. so the trigger mechanism is not on the steering wheel.
removing the batteries and waiting for the remaining electricity (from perhaps capacitors)to drain should be enough precaution.
ang nakalas ko na ay from a pajero blister fender or field master version - 3 lang wires that goes to the steering wheel (after the turn and wiper switch) - one for the horn and two wires for the airbag.
