There is a firmware update available for the older adapters. The SC can update the firmware for you.
Anyone ready for a laugh?
Ok, so I am continually surprised by the tech Tesla provides. And when I read your post, I read that the SC (SuperCharger) can update the firmware. I first thought that was amazing. Then I really questioned how as the supercharger cannot connect to the adapter. I started thinking about wireless comm options between the supercharger and the adapter.
Yeah, I finally realized that the SC
(Service Center) can update the firmware. Makes a LOT more sense.
But with Tesla, the first didn't seem as impossible as it would with any other brand.
