Got a few codes try to erase but couldn’t, car was in a crash driver fender snd smashed radiator core support, didn’t deploy bags, checked pretensioner for ohms, getting 2.4 on both, same with plug from pretensioner to plug under seat. Need help
checked pretensioner for ohms, getting 2.4 on both, same with plug from pretensioner to plug under seat.
I used a toothpick to push away the shorting bars, if you don’t you will get open or Infinity readings, with the shorting bar out of the way I get 2.4 ohms which is good, meaning the connector and the actual pre tensioner in the seat are good. I checked directly on pins of pretensioner in the seat and with the connector attached.How did you do the resistance checks?
I must confess until a few moments ago I had never read up on the purpose of "shorting bars" and what they were for and how they worked. I read just enough here at this link to give me a very basic understanding that might be useful if I ever have to check these circuits.

I do get infinity on plug that goes under the carpet to the module, so maybe a break in the wiring there, but not sure.
