Here are the symptoms: The red triangle appeared two days ago, with the vsc, abs, etc. , and the battery fan was running. it was a warm day, about 89F maybe, and we had just driven about 1/2 hour on the highway and then 15 on a slow local road. The car sat since then. Now, only the red triangle and the symbol that looks like a car with an exclamation mark remain lit. Dr Prius reports P3000P0A82 The attachment is a few seconds of screen capture from Dr Prius What does the code mean? Is it reasonable to clear the battery codes and wait and see if or when it reappears? (In other words, can I clear it and drive it, lets say locally if not a day trip.) Apologies, I am sure this must have been asked before. I did try to work through the search results for a while before giving up and posting. (Part of the problem is that there is sometimes more than one answer, and it is hard to know which is correct.) Thank you
