some of this japs make airbag will deploy by them self even heat or humidity can influence, they are also known as the killer air bags. I never check an airbag's resistance, volt/ohms meter induces/applies voltage in order to check resistance and yes a deployment can occur, although I have never seen one do it, if I have a trouble code that pertains to an airbag I just check the resistance of the circuit wiring but not the actual airbag regardless of what the manual says , it could deploy, temperature, humidity,static electricity and the unknown can happen. another reason why i like the masisys is so that i can diagnose this things from far away, I trust no tool and no one when my life could be at risk. some of the repair manual also just say to disconnect the battery before working with this system, but they don't tell you that even though the battery is disconnected capasitors are still charged and a deployment can still occur, which one has to clear caps before doing so.
