    Hello everyone!
    I need some serious help over here.
    Recently I bought a 2010 Toyota Prius ZVW30 from an auction in Japan ( I'm from Canada, we can import 15yo cars). Auction went fine, car in good condition, good auction list, no trouble. I won the auction and it got delivered to the port and sat there for couple of months to wait for shipping. Once the vessel came they couldn't start the vehicle and display would show "Hybrid system check". Looks like the car been sitting on the lot for 2.5 months. The mechanic came to check it over and said that 'the Hybrid battery system is broken", I asked for more information and codes and they sent me these:

    P3000-389
    C1259
    C1669
    B15E6
    P0A80-123

    What a mess Im hoping this is happened because Prius was sitting for so long and drained itself, but I'm not sure. I really hope there is no bigger underlying issues with this car. Currently they did something so the car only runs on the engine power and is drivable which is good because now it is shippable.

    I only have two choices here. Bring it over and fix it or try to sell it at the action so someone else can deal with it. If I try to sell it back I 100% loose some money depending on the sale price.
    But I'm really hoping this will be an easy fix and I should import this Prius.

    What do you guys think? Anyone had these codes before?

    • P3000 (Battery Control ECU) + P0A80 (Hybrid ECU) indicates the traction battery is in poor health or failing.
    • C1259 and C1669 are secondary/related codes from the brake or skid control ECU indicating that the hybrid system fault is affecting regenerative braking or stability control communication.
    • B15E6 is unrelated to the HV system; it’s about the car’s microphone wiring or the head unit.
    When a Prius sets P0A80 (“Replace HV Battery Pack”) together with P3000, the most common underlying problem is a failing high-voltage battery. Addressing the HV battery issue typically clears the regen/brake-related codes. The audio system code B15E6 will require a separate fix (checking or replacing the microphone).
