I noticed (via Visible Tesla) my car was only reporting a pilot current of 30A this morning... my HPWC is set for 40A. When I went out to the garage and looked, the dash said there was a "charging error" and the charge ring was blue. The car was charging, albeit at a reduced rate.
I reseated the HPWC and all returned to normal
It also so happens my car did a couple of extra charge port lock/unlock cycles when I plugged in my HPWC the other day.
Coincidence and/or bad contact?
What seems weird is the pilot current error. That's something driven by the duty cycle of the pilot signal, and wouldn't be subject to "reduced contact surface area" I'd imagine. I also have gotten a yellow ring if I had a bad cable insertion.
If the car doesn't get pilot signal at all, does it assume 30A for a 240V input?
