I don't believe there is a "reset" for the oil indicator light. The sensor that triggers that light is looking at oil level and oil pressure and is located in your oil pan. Mine has been on since I bought the car, but I have no indication that I am using oil (leaking, burning, etc) so I am assuming it's a bad sensor. I'll replace it eventually, just not a priority right now. The "reset" you are doing is for the FSS and like what was said before, it looks like you're doing it correctly and shouldn't affect anything else. The suggestion to check for codes should be your next step - that will tell you (and us) more of what we need to know.
