A hypothetical question for you if you see this MR Danner, and maybe you’ve already covered this in a video.
An ECM with a private CAN network to a VGT.
Or any CAN network comprising of just two parts.
Say you’ve logged an active code for lost communication.
The wiring is good and the terminating resistors and power supplies are good at each end.
Can you prove which end has failed the ECM or the VGT.

So I can see from this video that the upstream has values in (mA). Then, what is the normal range for it in mA?

Glad I have an electric and don’t gotta deal with so much of this anymore
