Getting code P3019 and P1E01! I reset the system and the car was fine for about 10 minutes and the codes came back.
Neither P3 codes nor P1 codes are standardized by SAE across cars, so if those are from a Gen 4 Prius, the place to find out what they mean would be a Gen 4 Prius repair manual (more info). My subscription isn't paid up at the moment, so I can't easily go look. By analogy to some earlier Prius generations, my guess for P3019 would be deterioration in the ninth block of modules in the traction battery. P1E01 I don't have a guess for.
Using Dr Prius. Car has about 150k on it. The graphical battery display showed higher voltage on cell 9 which I thought is weird.
Ok thanks. Yeah the 9th block shows about a volt higher than the rest which I thought is weird. The best answer for the other code was for the battery control module. I cleared the codes by disconnecting both batteries and went for a drive. Everything seemed normal for a couple miles and then the Hybrid system malfunction warning came back on. I also noticed the fan coming on and the battery stopped contributing power.
What is this business with adding an unedited quote, no relevant info, and a question mark, on a thread where someone has posted a question and others are at work on responding to it?
