Hello guys
my volt is 310,000 miles or so. original equipment - pretty happy.
got these 3 codes one more morning after realizing the overnight charge didn't complete (only went in 3-4 bars).
I figured it was a charging fault and clearing the codes would fix it.
vehicle drives fine, but every time I plug in, the charging light under the windshield will start blinking orange and the car isn't charging. turning the car on immediately reveals engine light and checking the codes giving me these codes.
the car drives fine, I can even engage mountain mode and the generator will charge the battery to half as it normally would.
but no matter what I do, plugging any of my 2 chargers (one at home, one at work) give me an automatic check engine light and these specific 3 codes.
what do you think is going on?
