    I recently got a new hybrid battery installed for my Toyota 2008 Prius. I changed it because Toyota had diagnosed P0AA6 being caused by a bad hybrid battery. I drove about 50 miles back home from the repair, and the car felt spectacular on the interstate! 3 hours after i took I picked it up from Walmart tire center for them to replace the TPMS sensors. It rained on my way home, I went to get the mail i reversed parked and BOOM P0AA6. I was in disbelief. I erased the code, and it came back twice. What could it be! thanks.

    P0AA6 this code has subcodes that indicate problem areas.
    Did they really replace your battery and just not erase this code from the error memory?
    It will be interesting to know in which area this problem occurred

    P0AA6, detail 526, and 612 | Page 2 | PriusChat

    Some trouble codes have what are called INF sub codes which give more information about the fault. Does the invoice from Toyota give the INF codes?

    I would expect that the dealer keeps records of the actual computer scan (but I don't know that as fact). They should be able to document that their diagnosis was correct.

    P0AA6 will set 2 INF codes. One is 526 (general isolation fault), the second (611, 612, 613, or 614) will point to the specific area causing the fault.
