When I worked at a Ford Dealer and got a a car with an airbag light on , some of the codes were related to airbag or seat belt pre tensioner resistance being too high or out of range , and you could disable the system , unplug the pre tensioner, or airbag and plug in a simulator that had a specific resistance to simulate the presence of a good component in the circuit , and if I do recall , I was able to watch WDS resistance or voltage graph change while wiggling the underseat wires leading to a pretension er.
I'm well aware of the dangers of trying to test an actual individual airbag or pretension er simulator, or the non isolated circuit while detonatable component is still attached to circuit with an ohmmeter , but more in depth information should be available in all wiring diagrams about each manufacturers systems as to what normal internal range of resistance of each component actually should be , so I can either purchase a component simulator or cut the connector pigtail off a spent component and make my own damn airbag or pretension er simulator with a Radio shack resistors soldered in series . If Snap On Compiled a comprehensive list of manufacturer's air bag component resistances in a little book, by model and year and sold a Blue Point box with about 25 different common style connectors and noid light style plug in resistors to make your own airbag system component simulators, it would save a lot of time and headaches. Maybe could even sell a box of common fuel pump connectors too with a loud Fiam horn . Plug it in crank ignition , horn blows
