Utilizing FAN controls

Hello! I'm using LSdroid, TunerPro RT with a 411 & OS 2156. I have preformed the SEGMENT SWAP on the TRANS, TRANS CALIBERATION, and SPEEDOMETER. However, the SYSTEM SEGMENTS were two different numbers of course. Will this mess with the "checksums"??
Also, how can I ACTIVATE the fans??It is programed for the manual fan currently.
