Multiple switches missing voltage on M92 Pins 6 and 18

[Calvin]

For pin 18: Please read my answer to your last topic:

No short on any rails but pin 18 and pin 36 no voltage

See title, also the leftmost battery pins have no voltage. Any ideas? Thanks in advance

Pin 6 is on a line to the pi3usb ic (mux ic for the datalines to the docking station) on the backside and a short on this line mostly indicates a bad pi3usb ic.
