cruise control not available

tl;dr I was going down the road and the drcc kicked off and the error message, "cruise control not available", came up. I cleaned the emblem and disconnected the battery hoping it would reset the ecu, and the problem persists. Standard cruise works fine.

Car history: The a/c went out a couple of months ago with 50k miles and I took it to a local hybrid shop. The guy told me he hooked their diagnostics up to the car and it was doing odd things to his scanner. He blamed my audio system that I have installed. Then he said he tested the 12v battery and it wasn't charging. After replacing it they hooked the scanner back up and it worked fine and he said he couldn't find anything wrong. He tested the electrical system to see if there was draw on the battery with the car off (testing the audio system install I guess) and said that was fine as well. So they put dye in the a/c. Lo and behold the condensor had a crack in it. They replaced the condensor, charged the a/c and returned the car. Everything was working fine. Even went on a 5 hour road trip. Then driving down the road with the cruise on, the car decelerates and that message popped up with a big orangish triangle. Turning the cruise off and turning it back on gets rid of the message and the triangle, but comes right back on successive attempts. I hooked up my Carista to it and the only thing I could find other than "No fault codes" or "No ECU present" was this:

Heater & air conditioning
Part # suffix: 47520
Fault codes:
U0163 Lost Communication With Navigation Control Module

I'm not seeing an option to reset codes with the Carista.

 

Looks like it's at 12.6v car off. 13.6v car on.

 

That was after the car had been sitting for 3 hours. I did unlock the car to open the hood however. I wouldn't think it would make that big of a difference?

 

Emblem is spotless and I haven't hit anything (to my knowledge).
