If you data looging well your also scantoooling! Depends on how the .adx is written but normally all codes are in there too. There is a way to clear codes on 8192 baud systems because they are bi directional. but 160 baud like 1227747 is only one direction and you have to disconnect battrey to clear codes.

So what car are you working on? what ECM or mask? Then we can get more specific...
