Hi, my comment would be that the Toyota's are really well made and the manuals are very thorough. But you probably need to flip through the manual several times. There is a lot of detail. You also need to give yourself time. Some repairs take a lot of persistence and patience. I don't have a manual for your model but ti seems the C errors are all to do with the traction controller and contacts. If you like email me a copy of the manual and I'll do my best to analyze the situation for you. jmhgill AT hotmail Dot com.
