You have a couple options: Disconnect and reconnect the 12v battery to reset it. Or get an OBD2 scanner that can clear codes to reset it. If you have a manual you can shut the engine off while coasting and then turn it back to run making it "pop start" and that should also restart the IMA.
Well I learned that once a lithium battery goes all the way down. It basically had to be jumped off for the charger to read it. So I'm guessing the same thing applies to this situation. The battery goes so far down that it has to be jumped again in order for it to operate.
It would not operate at all without the hybrid battery the 12v battery dies and does not recharged at one point it was showing the 12v battery was being charged but does not anymore I was thinking maybe the fuse on the battery pack blew but no haven’t checked at this point it just sits in my driveway the care starts and runs great it I charge the 12v battery but the 12v dies shorty after using
