12v will set an airbag off i have done this on a bench for giggles
the checking circuit measures the resistance of the firing charge this is probably done with a pulsed very low voltage <5v
the firing voltage is probably up to constant 12-35v
measure the voltage that your multimeter reads Ohms @ if it is very low id measure the resistance of the bags and see if they match if they dont you could add resistors to bring the Rx8 seats to the correct value
this is my opinion none is based on fact other than the first line
its a little more complexed than you think
the air bags are controled by an ECU so it is all computer controlled
the code readers just read the stored data in the chip not info in any of the bags
