Hello! I have a Prius that suddenly stopped working while driving. Had to pull over and get it towed. The 12v aux battery was fine. The power button won't start the car when the FOB is the key slot. Any ideas?
How do you know the 12V battery is fine? Did you check the inverter coolant pump to see if it is running when the Prius is IG-ON? Sometimes when the pump fails, the AM2 fuse will blow, and in those instances the car will not operate.
