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.
