Macbook Pro 13'' - A1989 stuck at 5v

[nosinformatica]

Hi,
Preface : My primary job it's not repairing logic board, so please excuse me.
The Macbook A1989 is stuck at 5v at 0.3A on three usb-c port, and in one port no absorption, so the incriminated chip may be the CD3125.
I'have read that these mac have two CD3125 in daisy chain.
How can i confirm my diagnose before reballing it? Someone have experience with this issue?

Does the meter jump to this current draw value or does it climb up to this value?
