Multiecuscan

hello, I'm new here. I have a fiat doblo type 263.e asked the elm and yellow connector or a3.With this would be enough for my fiat? I have many doubts but I hope that when the elm arrives and buy the payment license in the next week they go clarifying, I'll have to go researching. A question I have is whether in fiat or multiecuscan there is a guide how to proceed to reset maintenance or oil change for example. Before I had mercedes benz and had wis that indicated How to proceed, but in fiat I have no idea. Sorry for my English since I am from Spain and use a translator. Thanks in advance and any help you can give me is welcome. A greeting and a thousand thanks
