    Hello, I’m looking for some help diagnosing the red triangle on my 2005 Prius. I have a P3000 code, which seems to be a generic hybrid battery error. I was hoping Dr. Prius would give me more specific details, but I can’t get it to complete a full battery test. It tells me that the battery is too cold to continue the test, but I can’t see why. It’s around 55–60 degrees outside, and I drove the car for over 40 minutes. The battery monitor shows temps above 90 degrees, but it still won’t complete. The active monitors are confusing since the numbers constantly change while I’m driving. Does anyone have any insights based on this and the monitor data shown in the YouTube link below?

    It doesn't want to let me upload a you tube link because i haven't posted enough so if you want to see it to help then PM me I guess

    Thanks!!

    So let's start with some basics you have a 2005 how many miles and is this the original hybrid battery as far as you know you have no reason to believe fefurb etc?

    Look into a decent refurb in the 499 price range and clean front end computer take silver back off see the mess.
