Check diode mode to ground on T2 data lines connected to J6100; compare readings with good board.

I don't have a good board to test on 
only donor board that a bunch of parts are taken off of. here are the diode values of j6100. pin 26 (mesa enable) is ground. i'm assuming this is a dead t2. have 2 questions. is it possible to be anything else besides t2? and second question is it possible to replace the t2 (i know data will be lost) or is it tied to cpu?

If USB-C ports switch to 20V, T2 is partially working.
However, cannot discard internal damage caused by liquid spill to its data lines.
Check the power on sequence for T2 boards; already uploaded on the forum (01598, 01055 boards).
