Hope this helps. Vida also shows disconnected with no battery voltage or key pos. My vida dice works fine for my 2000 c70

I can’t

Why? If you can see errors that means you can do screenshot. Just use button Print Screen and Ctrl+C in the "Paint" application. After this you can edit (if need) and save it to file.

It is very easy. Like example you can see, all your modules communicate to each other trough CEM...
But, if you confirmed CEM does not has some damages, looks like there is some issue with other module or wires.

I put an oscilloscope on it today but I couldn’t see any hiccups or jumps in the can circuit. I’m about to just drive it till it dies or sell it before it becomes any more of a headache. Feeling very defeated right now.

Can you show screen with activated Network tab?

Here ya go

Is it situation only when engine running or when it stopped also?

[2000c70hpt]

It happens in either situation.

What can I say, you have to use oscilloscope in this case... at least.
