I have a 2010 Toyota Prius that won't start, and the dashboard displays a "Check Hybrid System" warning. I've already tried replacing the 12V battery and resetting the system by disconnecting the battery and pulling the white cable near the fuse box. I also disconnected the orange service plug for the high-voltage hybrid battery. After doing this, the car started briefly, but within two minutes, the "Check Hybrid System" warning reappeared, and the car wouldn't go into drive mode. Now, it won't start at all.
A good next step will be to search this forum for how to read the trouble codes that will show what the car thinks is wrong.
Google a u t e l a p200 and go buy one It's on Amazon it's white If it's not white it's not correct that'll help you solve a whole bunch of problems and might be the best $63 or so you spent this month If not oh well you need to get a capable bi-directional scan tool so you can get all the codes out of this fancy car that's hard to read in a nutshell or you can go find a thread in here about what scanners work with all this nonsense and read about 50 posts to come up with a list of 5 or 10 The one I'm telling you is probably one of the better ones for the least amount of money in a nutshell but that's where you are.
