    I have aGood running 2001 Toyota Prius. After changing 12 V battery, I got Coach P 3000, P 3009, C 1259. I don’t know what happened. Any suggestions?

    the same thing just happened to me, without the C1259. Were you able to find out what had happened?

    Same. 1259 and a few others. I changed the 12 volt and am eliminating possibilities. Seems like I get a new code every time I touch this car. Good luck.

    Did you pull the traction battery disconnect before disconnecting and reconnecting the 12v battery? If not, that could be your issue. Did you clear them, did they come back?

    I did not disconnect the traction battery. I have cleared the codes, and they come back.
