[Terminator]If the T-1000 had been successful in killing the T-100, Sarah and John at the end of T2 what would it had done afterwards?

The Terminators were launched back in time with no method to achieve further mission details from SkyNet and no way to communicate success or failure back to SkyNet. 

In that context they are a desperate last-ditch effort to stop the Human Force's success during the final battle. 

It is unknown if secondary objectives were programmed into the Terminators, no mention of secondary targets are made in the canon films, and their singular focus on John Conner seems to suggest that secondary targets may not have even been provided to them. 

In the first film the Terminator was not even sure how to even begin to find the "correct" Sarah Connor and was just destroying all of them in a comprehensive manner. 

If they had any data about Secondary targets, it makes sense that they would go after all of those Secondary non-defended once they hit any kind of defense or snags and discovered that John was defended (Since SkyNet was destroyed before John reactivated the time machine, it had no idea that there would be any defender's going back in time to try to save John), thus it would be up for thee Terminator in the field to perhaps make that judgement call. 

Where-as the Terminator in the first film shows little adaptation, and acts more like a sledgehammer brute-forcing all of the situations, the T-1000 is more subtle and creative, but also doesn't engage in any attempts on undefended secondary targets while pursuing Connor, perhaps suggesting that he had no other significant mission details. 

Additional mission details if Connor is destroyed may not have even been handed down by SkyNet and instead would be a matter of personal creativity. 

The T-800 would probably find a cave and stay out of history's way until after Judgement Day, and return to SkyNet for additional orders. 

The T-1000 would probably continuing impersonating authority figures, and pursuing potential mission goals, since it was presented as being more autonomous and creative and wily.
