    I have a 2004 Prius.. Car started to run rough a shake... Battery meter went low.. A burning smell.. OBD2 code P0000 U0111.. I did some research and seems that there is some communications problem with the power system? Has anyone had this problem? I do have a lot of miles on it.. Over 400,000..

    If accompanied by a burning smell, you might have had this happen.

    I could not notice a burning smell as im often smoking if driving or working on a car. Where is that pin? in the HV battery? because Ive swapped my battery out several times still a problem, all be it different codes, very confusing , see here if you feel like helping me out or helping save Rodney King's daughters former prius from becoming scrap.
