Low end scan tools will give generic OBD codes for common engine problems such as a cylinder misfire. It will then be up to the user to determine the cause such as a bad plug, wire, cap, rotor, etc. It's usually a process of starting with the most simple fix, and progressing to the more complex. I had a number 2 cylinder misfire code which required the fuel injector to be replaced before the code was cleared. In addition, manufacturers have their own proprietary codes that are more specific, but require a computer with their software. In either case, code scanners will not tell you the fix for any particular code. It still requires someone who understands what the code(s) means and the most likely fix.
