I have repaired the broken power transfer terminal , whoever still am showing 2A3F and 2A77 error codes and am in limp mode. (Both related to vvt)

So, doing some dumb Google searching I have found possible causes being:
-bad 40A orange fuse for VVT in engine bay Ebox
-bad blue VVT relay , also in engine bay Ebox

I have tested the 40A fuse and believe it's good, never used a DVM, however I get a 0.01 reading on the lowest possible continuity setting.

I'm unsure how to properly test the blue relay ( pn: 61.36-6915327/01), however when doing the same as I would with a fuse I get the following:

87 + 87 : 0.00
Either 87 + 30 or 85: no change on DVM
85 + 30: 0.095

All of which I think are expect values by reading the little diagram on the box.

Are there any other thoughts or suggestions for further diagnostics before I start to think I fried something in my VVT system somewhere, and have to start learning those wiring diagrams lol
