    Hello everyone I joined today in hopes of finding some help with this issue, my 2012 Prius with 149,997 miles was running just fine when out of nowhere while breaking I got the message "Check Hybrid System Stop the vehicle at a Safe Place" the check engine and a yellow triangle with exclamation point lights and the abs light came on, The "Ready" light was still on and I was able to drive home and plug in my scanner and I got the following codes: P0A94, P0C3F, P0A7A, C1259, C1310, B2784, when this first happened I was still able to turn the car on, the engine was running constantly unlike before that It only cycled when charging or full power needed, but then the next day I couldn’t turn the car on at all, all the lights and radio will turn on but I don’t get the “ready” light anymore, the engine doesn’t turn on, pretty much I can’t move the car anymore, the check the hybrid system messages is still on and also I got more codes than before P0A94, P0A09, POA0D, P0C3F, P0A7A, C1259, C1310, U0110, B2784, after doing some research and trying other things such as cleaning the fan of the hybrid battery, getting a new 12v battery, and just looking for any other less expensive solution I bought and changed the Inverter, well that didn’t work, I plugged my scanner for a third time and now I just have the following codes: P0A7A, P0A94, U0110, C1259, C1310, B2784, is there anything else I could try? Do you guys have any recommendations?, anything will be appreciated and helpful, and I apologize I know this is a long text.

    I have been using the Injectronic CJ-327BT
    I bought it from autozone as soon as I started to have this issues, it works with Dr Prius, but do you have any recommendations?
