The problem is: the cab controller recognizes the switch. You can see it turn on and off with PACAR ESA program. But the ecm doesn't see it.
If you enable the switch function in INSITE the fan runs continuously, meaning it thinks the switch has malfunctioned.
I had someone experienced with this look at it, and they said something in the drop down menu from the switch option in INSITE is missing. That's as far as they went at the time.
Anyone have any idea where to go from here?

The fan switch in the ECM most likely needs the J1939 address for it assigned to it. I think this can usually be done in Insite, but you need to know the correct adress for it.
