Was trying to figure out how to get ecutek up on my tesla screen and stumbled upon this...

What is the white connector for? It's under the dash next to my obd2 port.

I have that connector also. I can't find what it's for in the SM.

I think it's where you plug in the modem 🤣

Knowing Infiniti, it is for a 56k modem. I think there was an AOL disc in my glove box.

I would guess it is some sort of diagnostic port that a tech would connect to.

It’s for the TPMS system. You can reprogram and read trouble codes from there
I'd like to see some documentation, if you can point me in the right direction. How do you know it's for TPMS? DTCs are read from the data link connector (OBDII port).
