    Had a customer car with DTC P0A9B in 2005 Prius with 170k miles so out of warranty.

    Car would code immediately when turned on but would drive fine, 45MPG average etc.

    Dealer had told customer solution is to "replace entire HV battery assembly". .

    Customer battery ECU was 89890-47070.
    Got a slightly newer battery ECU 89890-47071 from a hybrid recycler in Denver. Replaced only the battery ECU, cleared codes, no more problems. Car now running great.

    Thanks to Eric at Adopt-A-Part for hooking me up with a good used battery ECU at a fair price.

    Nice work. If there were no driveability issues that provides a good clue that the traction battery is indeed OK.

    Your traction battery has a warranty life of 100000 miles in most states and 150k in California. And their are lots of tech centers selling refurbished batteries. And a guy in Tampa sells this charger to equailie the cell

    but the o/p said the car had 170k, and the battery was fine.
