Macbook Pro 13" A1706

I have one strange issue with Macbook Pro 13" A1706 (touch bar) 4 TB ports
Issue is that all 4 ports are working but on one port only one side (when i rotate connector 180 degree there is nothing (ampmeter is not turned on at all) and charger (original apple) is put to protective mode, I have to unplug USB from the power brick to enable it again.

I've tried multiple USB-C ports (one one side all ports all sides work when i reconnect it to other side both ports work but one only on one side)

There is no issue problem on the board (no liquid damage, no damaged component), connector is in great condition

I've also tried to check with thermal camera but nothing lights up ....

Remove all power. Meter in DIODE mode. Red meter probe to ground. Black meter probe to point to test. Take the measurements of the bad side USB Type C connector and compare the diode mode measurements with a known good connector. It is possible that the ESD TVS diodes are damaged for that side of the USB Type C connector blade.

It looks like this is the bad side

Share a view of this meter on a good and working port.

This are meassurements from other side (where are two ports) that work both sides

If the USB-C port is not rotten, then I think it's time to change the SD3215 port that doesn't work

See a lot of red there in the test results. We recently purchased this tool and it arrived late yesterday. Will test it against some units in the building but suggest that you do the same. Insert this tool into a known good Type C based macbook to compare the results.
