May we know what vehicle do you test? And what's the fault code? Usually our tool will show you the fault code definition for your reference. As the repairing information, we will add it in our Maxisys tools step by step.

 look into all-data, ondemand5 or identifix. you will need one of this software to be able to read diagrams, trouble codes, diagnostics etc.  can't do without it. the scan tool will just give you trouble codes and the definition of it but there is much more involved in diagnostic.
