Good morning everyone. I am working on a 2013 Lexus RX350, with communication issues with multiple modules: Seat control module, airbag sensor assembly comm circuit, restraint control module and GSW. The driver seat does not move and the airbag light comes on. I am trying to read the diagram of the CAN Lines, but I do not see any restraint module. I see the Airbag Sensor Assembly. For some reason, I don't see the passenger side seat module (I would say that the truck is not equipped with it) Neither seat works. I would like to know if CAN HI and CAN positive are the same. The seat control module has CAN Pos and Neg going to it. Is it a low speed CAN? What voltage should I expect there? I don't feel light ohming the CAN Lines to checks for opens and shorts. As far as the Airbag light, it is started after the seat belt was replaced. Can a bad seat belt pretentionner trigger the airbag light? Would a bad pretentionner cause other modules not to be able with the Airbag module?  Thank you.
