    Hello again,

    Last night hit -21 degrees f where I'm at. Went to go to work this morning and my prius wouldn't start. All kinds of lights came on, but 'ready' never appeared, and the P, N, D, R, and B started flashing.

    I figured this probably isn't good.

    Grabbed my obd scanner and pulled u0293. Lost communication with HV ECU.
    Pulled these codes from the LAN Monitor in the MFD:
    01-DC 190-17-3
    01-D8 190-14-1
    01-D5 190-48-F
    01-DB 190-B4-F
    01-D9 190-D5-1

    01-D6 -00-1
    01-DC 110-B6-F
    01-DD 110-B6-3

    Is there a reference anywhere I can look these up? Maybe there's a pattern or something.

    Car sat all day (took the ford to work), got home a few minutes ago, still nothing. I feel like this is going to get expensive really fast.

    On a probably irrelevant note, I had 2 flat tires the day before. Can't imagine that would have anything to do with it. I'm open to suggestions though.
    Car is an 08 with 109k miles.

    Do you still have the original 12v battery? Maybe it doesn't have the power to start the car. I changed mine out recently and it was registering 11.5 volts I think. You should check your battery before panicking about something too expensive.

    Probably is the original, I'll put a load test on it in the morning. Thanks for the suggestion

    That is more likely your problem, just the original 12v battery.

    Note that those LAN codes mean nothing. You can only get reliable codes read via one of the Prius specific code readers often mentioned here. But I agree, your 12V battery is very likely the problem. Put a charger on it. If you try to jump start, be very careful, absolutely certain, of the polarity.

    Not wanting to chance ruining any electronics, I took the battery out and put it on a trickle charge for 6 hours. Put it back in, and the car started right up no problem. Looks like I'm in the market for a new battery. Thanks everyone

    It is a common practice to hook up a "smart charger" at the jump post under the hood. Simply attach the positive side to the jump post and the negative side to the nut on top of the strut behind the fuse box where the jump post is related. Since the battery is a AGM type, it is preferable to use a charger/maintainer that has the AGM setting. Charging parameters are different for AGM type batteries from the traditional "flooded" type batteries that are found in most applications.

    As long as you are careful about polarity, you should not have any problems charging and or maintaining your 12 volt battery without having to disconnect it and or remove it from the car.

    Best of luck to you.
