Pablo I need you're help with a problem I'm having with two 05 retired Schneider freight liners century class. The cruise works fine when you have PTO going on and when you're driving bobtail as soon as you hook up a trailer cruise will not work anymore I have checked all the wiring and everything seems and measures out fine I replaced both air switched for the service brake as well as parking brake checked all cruise switches via diagnostic link and everything works. Blocked off the glad hands to make it seem like it had a trailer sometimes cruise works sometimes it doesn't. Now I'm stumped. My question is does Schneider do anything with the ECM calibrations to affect the cruise control. Because I can't think of anything else that could cause this. Thanks in advance.

Seems to me not. I can see that Cruise controll is programmed like on other trucks.
Lets compare calibration
