Info on these DTCs

Anyone have a breakdown of what the DTCs mean?
I was doing a quick charge tonight, plugged in, it failed and said the car needed to be turned off. Unplugged and tried again, it failed and said the car needed to be turned off. I unplugged and tried again, it started charging. When I came back to the car and went to leave I had the yellow picture of the car with the exclaimation powered down and back up and the yellow car icon is off. No issues driving home it charging at home. Anyone have any ideas?

That warning light indicates that there was a problem when charging. Nothing to worry about if it does not appear again after powering down.

Can’t help you with the DTCs.

Those DTCs are related to charger or charger communication errors. I get those errors from some DCQCs and my 2015 will not charge again without clearing the DTCs.
