I think I got list with the Rinda I bought . I think you can pick them up on the internet also. The Rinda had a great troubleshooting section for help with diagnostics also. Remember with the Rinda, not all the engine problems will have a trouble code. They might be way out of parameter, but still not throw a code. My MAP sensor was my main problem, and the dealer I took it to could not diagnose the problem . When I replaced it all my problems went away. Good luck Dave-R
