Great video, Thanks! I think the fastest way to diagnose when you have a single module pulling the network down is to test at the DLC as you did, then go straight to the module in question and test the pins of the harness (unplugged) and see if it's good there. If it's good, you know there is no high resistance or shorts, etc. Then plug in the module and watch it go bad. People always say you don't need a scope for networks; technically, they are right. But come on You used both and you can clearly see the difference, with a multimeter you're never fully sure. with a scope, you see the fault! Really enjoyed Thanks!

Good video get yourself a breakout box would make it quicker to diagnose liked subscribed
