Door ajar (Nothing else showing on screen!)

This happened to me too. At the next stop light I opened and closed the door and that fixed it. It never happened again.

 

I ran into this last night too, but for an entirely different reason. I had just come home from an EV
show-n-tell event that ran into the evening, and had been running extra lighting from my 12V inverter.
It has its own battery but can also be tied into the car for recharging; it's a direct hookup that comes
off my splitter from the front power outlet. [It can also serve as a jump box for low-power bootup
scenarios like a Prius or EV, as it has a heavy-duty connector straight from its internal 12V brick.]

I packed things up and headed home, but left the inverter connected to keep it charging on the run home.

Which meant that when I powered down, the 12V inside the inverter was still back-powering the outlet
circuit.

The car started dinging at me, like it does after a single no-brake press of the power button. But without
the yellow key icon, just the screen with the open driver door diagram and nothing else. A little later,
the "12V discharge" warning popped up on the center screen. It took me a bit to realize what was
actually going on, but after pulling the inverter connection everything went back to normal.

I haven't traced the diagrams to see what-all my little box might have been powering in the lee of
the power-outlet relay, but the result was interesting.
