Passengerside marker light in-operable

Hey forum, I am having a strange problem where all exterior lights work correctly except for the yellow right side marker light. It reads out 6.34 volts when set to running mode (always on) and 12 volts when set to blinker mode (12 volts on, 6.34 off) I've tried replacing the bulb and also tried swapping the bulb socket with the working side and that didn't work either. I did some more readings and think it's a problem with the positive wire. Has anyone had a problem like this? What could cause all lights but this one to work? Thanks.

maybe a wrong fuse, wires corroded that's where I would start.

also one thing that people never check of clean is the grounds the NSX is known for acting funny when the grounds are not good.

Thanks Sean. I'll take a look at that later today.

So grounds are good and so are the fuses. Sorta lost here. Is it the integrated control unit?

Took it to Acura. Turns out it was in-fact the icu.
