There is a Special tool we used at the volvo shop,its just a resistor that replaces the airbag plug.In other words this resistors plug is identical to the plug on the back of the airbag.It fools the SRS (Suplimental Restraint System) into thinking the bag is still hooked up.Therefore no SRS light.
I do not know the value of this resistor.
DO NOT HOOK UP AN OHM METER TO YOUR AIR BAG!!!!!!
The small amount of current that your meter uses to operate CAN SET OFF THE AIR BAG!I have seen this happen!It will blow your head off your shoulders if your down at it.
So if you could find out the resistance of the airbag,you could just pop a resistor into the wiring harness that plugs into your airbag.Done..
