    Did the engine turn over and run?

    If not, you are going to need a Prius aware, OBD scanner to read out what is going on.

    The easiest way to reset all Prius codes is to disconnect the ground wire for a minute or so. In theory, the run-down 12V battery might have put the control computers in an indeterminate state showing false errors . . . but very few people are that lucky. Still, disconnecting the ground eliminates that hypothesis.

    Looks like it's time for a new traction battery.
