hey, need help with why i would lose fan control, i made ecm image and template, before flasing ecm with new cal, i also made a backkup with calterm of the old file, fan works with old file but not with new one, settings in insite are the same on both files, problem is fan will not shut off, it is set up 0 volts in insite, when i swich it to 12 or 24 it shuts off but then the manuel overide switch does not make it come on, did a file compare with calterm cant find anything that looks suspect, its an 871 and pete 389, like i say all settings in insite are idedical, would sure apreiate any help, my other trucks this same cal works fine dont know what the isssue could be
