2020 hd2500 cruise stopped working

[Pythonhunter]

My cruise will turn on but will not set. Brake switch seems to be fine and I’m getting no codes? 
Please help, I use my cruise all the time. Fuses seem to be fine also 

 thanks for any help

I'd say then the issue is the switch in the wheel itself, the left steering wheel control.  Or there's a code stored you didn't scan yet fully (think ABS, traction control, etc.).  Any other warning lights on?  Is the check engine light on?
