has anyone ever seen an issue where the PCM is contantly grounding pin 42 (low fan switch). Everytime I turn the truck on, the fans kick on immediatlely instead of waiting for the Fan on time programmed in my tune. I thought maybe it was a problem with the relays but then i put a volt meter to the wire that is curretnly in 42's slot and it was definitley showing a grounded connection. If anyone has any idea as to why the pcm would basically have the fans on at all times when the vehicle is running please let me know.

Heres the tun incase you would like to see if it is the problem but im almost positive that it isn't
