Should the “Cooling Performance of the Hybrid Battery is Low” warning stay on after cleaning?

    My wife's 2015 Prius threw this warning about a week ago and I removed about 1/4 inch of lint from the filter. She doesn't drive much.

    Does that warning go off by itself? Can/should I clear it with tech stream? How long does it take?

    Did you clean the fan and the ductwork leading to it? If you had that much link on the inlet filter, the rest is likely pretty snowed in as well.

    See video 21 here:

    But do take a look at this first:

    ^ in a nutshell: no need to remove rear seat.

    Also, you CAN clean the fan without removing it; just getting down to it, but leaving it plugged in and bolted down, you can clean it fine say with Q-Tips. Don't make more work for yourself.
