Drill the holes so you don't ever have to pull the panels off.
The TCU is the modem in the car, its what talks back to Ford to send all the telemetry data as well. This is not an update for Tesla charging.
Since the Tesla charger is going to talk CCS protocol to the MachE, I would think most of the updates are going to be happening on the FordPass / Blue Oval Network side in order to unlock this for us. Other than the in-car nav "knowing" about the locations, I would think the only other thing needed is the adapter itself.
There is likely some kind of update for communicating with those stations needed since we're getting plug and charge with them.
My rudimentary understanding of Plug-and-Charge is the car identifying itself to the charger by sending its VIN, and the the charger performs some kind of lookup to say "Yea, I know how to bill you for this".
I believe the standard uses PKI Certificates for security so its not just sending data in plaintext. At the very least they probably have to add in new certs to trust from Tesla.
Good call, didn't think of that. Keeps someone from spoofing a VIN and charging on that account.
It always says that. But USB updates are done with the car running.
There is a fall-back if the USB doesn't work it will go through OBD, which will take hours and would require the power supply.
That means it was probably just a config update and not actually updating the software level.
