Do you get PPBUS_G3H?
Both USB-C ports have the same behavior?
Any history available?

Diode mode to ground at PPBUS_G3H?
Be sure F7000 is good.
Post U7000, basic voltages; P_IN, AUX_DET, VDDA/P, SMC_RST_IN*, CBC_ON, EN_MVR, A/BMON.

I don't see the other voltages.
Try changing U7000.

NO!
Normal, is 0 ohm resistor.
Post again (all) above mentioned voltages.

Not so many.
I was expecting A/BMON (CHGR_AMON and CHGR_BMON).
"PPDCIN_G3H_CHGR_AMON=5.2"
What's this?
Missing EN_MVR points to U7000 problem.
May also be a problem with Q7030/40, or their associated components R/C7030/40.
"PPBUS_G3H no short"

Check in reverse way too (black probe to ground) and compare both readings with good board.
May have bad solders unde U7000, or bad chip.

Compare diode mode reading on PPBUS_G3H with any big coil.
Should help comparing with good board.
