It was 20* this morning, truck had time to idle and warm up. I went to the construction site to see if they needed any help, just paving today. So my truck idled for about 10mins and when i got in i saw the cel light. Checked them with edge and got U1026 and U1064.

U1026: Lost comm with transfer case
U1064: Lost comm with body

Did it just have a glitch? everything still works. It will shift into 4wd

Anything helps, TIA
