One of my rav4ev's (the one I am keeping) recently started new behaviour.
When I return home, my (open)EVSE is in sleep mode. (timer enables it after 10 pm for cheep electricity ToU)
I plugin the J1772 plug: both LED's stay off, don't even blink once.
Immediately the humming sound of a coolant pump starts: what it normally would do if the onboard charger _is_ running (which it isn't) to cool it.
I checked after an hour and sound was still there.
This morning, after charging to "normal" after a couple of hours it started doing the same (J1772 was still plugged in, openevse was sleeping on timer)
When i plug in the J1772 in my other rav4ev, it stays silent
Power cycling the 12 volt battery didn't help: same result.
I even checked with the supplied trickle charger:
Just plugging the J1772 connector in and the humming starts

I measured voltages on the 12 volt batteries:
The one with the humming sound has 13.04 volt (charged at night)
The one not making the humming sound 12.4 volt
Any ideas before I make a trip to the dealer ?
