How to reset code after home repair

Hi, what is showing error? is there a warning light that will not resolve? What was checked? What was repaired? This is such a wide open question so it is difficult to know what is going on. Generally speaking, a fault must be diagnosed then repaired. The code must be cleared using a diagnostic tool, and then retested. If the code returns, there is still a fault that requires troubleshooting. Now, if there is no diagnostic tool available to clear codes and retest - then the only other possible thing to do is disconnect the 12 volt engine battery for 10 or 15 minutes - then reattach and restart the vehicle. Most of the time this would clear codes -- but it can also erase adaptive strategy of engine performance and require 're-learning' the way the vehicle runs also.
