    2012 C Prius Four Red 120,899 Miles No Bad Cells? So I Went To Start My Car. I Got All The Lights On The Dash And Stop Hybrid Car In Safe Area. So I Pulled Out My Code Reader On My Computer VCI Techstream By Toyota. And Here Are The Codes I Got. I Checked The Hybrid Fan And It Was Dirty So I Cleaned It And Still Got P0A80.

    If the 12v battery voltage is low you might get any number of computer fault codes. When did you last replaced it? (Or charged it ?)

    *Pepboys has a larger capacity battery for a lower price tham Toyota that only. requires the bracket to be bent.

    If worse case and you need to replace the traction battery you have options.

    Check my threads. I have replace the 12v lead acid and the traction battery and the help members gave me plus my descriptions might be valuable.

    Jump the 12V and see if it starts normally with no codes. After you jump it you may still have the check hybrid code. Reset it.

    It tested good the 12V it was at 12.71 off and 14.60 on it was never replaced before so why P0A80 With good cells. I cleaned the fan In back. What is the U0101 code anyway? I never took the traction battery out just the cooling fan and clean it.
