SD card 1-bit mode issue

I have a v1 switch and Hekate is giving the error that the sd card is in 1-bit mode. I checked diode readings and the Dat2 pad is reading OL compared to 0.5 on a known good board. Does anyone know where this line goes? Hopefully not the CPU…
I’ve circled the pad in red in the attached diagram.

it goes to backside this orange line and straight into APU

Thank you @jkyoho as always!

Unfortunately for me, OL on the other side as well :pensive:

@jkyoho What would you do in this situation? Just curious if it’s worth it to reball the cpu or just keep the switch stock?
