I really need help now. I've tried so many things, and Nothing is helping me get my 2011 galant fe cruise to work! No service lights on the dash anymore. There were no more codes either, until today. Now my AC has stored a U1120,..1. engine(can message) 2.ev-ecu(can message)3.Can-C bus circuit low... and I do not know what that means. I also don't know if that has anything to do with my cruise not working, but I have no other direction to go now for it. Is there anyone that could possibly steer me towards a fix? I need my cruise!
