One more for you! Plate is in great condition without any sign of oxidation! I’ve tested another keyboard and nothing, and now I don’t know what else I can do! I know the problem has to do with sensors, but I don’t know what to analyze in this case. I await instructions, thank you!

Try first disconnecting webcam cable.
Also test with known good trackpad; its flex can cause problems.

Procedures performed and continued the
problem. Can you tell me how to use Apple Service Diagnostic to get information about which area the problem is occurring?

ASD 3S144 is the version corresponding to your machine.
I'm sure you can find lot of info, even videos, searching with Googlr.
Good enough to run EFI version only.


Just for test, remove first R5222/3 and check if symptom changes.
You can also test disconnecting BIL (J6955).
