    This is in relation to a 2013 Yaris hybrid 1.5l 178k km.
    I've gone through the process of trying to recondition the battery modules
    after the P0A80 fault code but after cycling them several times (will do a write-up
    as soon as I have time/may benefit someone) , I came to the conclusion that
    an offer of a newer used complete battery with 1 year warranty would be simpler than trying to
    scrounge around and match modules as our market is small and it would mean
    importing and probably all sort of headaches.

    The problem is that the guy I purchased the used battery didn't do a proper job of balancing the modules, voltages seem low, there was a weird drop in SOC at one time and P0A80 appeared again + P0A7F.

    The guy is standing behind his 1year warranty and will fix this but I wanted to get better acquainted with the info Techstream is giving for the fault- would appreciate if I could get a few comments on why Techstream
    marked certain data in orange and whether there is anything there that could possibly be pointing to
    other causes.

    Wire all modules in parallel. Then charge to the middle voltage.

    GOOD LUCK!
