Lots of Dash Lights came on, engine won’t start and car won’t ready, think it’s the battery

    Hi :)

    a few days ago I was driving and the car beeped at me, the red triangle came on along with the check engine light and the ((!)) light. I pulled over to try to figure out was wrong and couldn’t, so i drove home. When I tried to start up the car again the next day the engine would no longer come on and now the traction control, abs, and vsc lights are also on.

    I heard the rear passenger air intake working really hard so I tried cleaning out the cooling fan for the hybrid battery pack but it wasn’t dirty. I also tried disconnecting and reconnecting the 12v but all that did was make my gas gauge blink at me.

    here are my codes from my OBD scan:
    p0571, p0A0D, p3000

    and here is my graph from dr. Prius, I’m not really too sure what this graph means but I know it has to do with the cells inside the hybrid battery:

    from what i understand it’s probably my hybrid battery that needs replacing, but before I drop money on the repair I wanted advice from you guys on what else I can trouble shoot and what all this info means.

    thank you :)

    How long does it take for lights to come back on after your clear error codes? Right away? Or do things work normally for a brief amount of time?
