I have a 2005 prius with 38,160 miles I started it and shut it off and then tried restarting and now does not want to start. The ready light does not go on and the start button becomes orange. I ckecked my 12 volt and it gave a reading of 12.2 volts. These are the engine codes that come up: U0111 comes up twice C0200 C1259 C1310 Any ideas what this problem could be?
priuschat is organized into sections related to different models and thus years of production. You may get more insights from finding the section that fits your car as the section for the v is a 2012-2016 era wagon forum.
I don't think it is good anytime... 12.2 with the car off is bad because the battery is dead. 12.2 with the car READY is bad because the inverter isn't charging it up to 13.8-14.2
If you checked with the car in READY, then inverter or battery. If you checked with car not in READY (most normal), then it is the 12v battery. Your symptoms sound like a bad 12v, your readings indicate a bad 12v, so if it quacks like a duck...
