AlfaOBD and LinkMX+ Problem

375 Views 5 Replies 3 Participants Last post by  BS10
Hi all, I am new to doing this type of stuff. I have downloaded AlfaOBD and I am borrowing my buddies LinkMX+ to test this out but I am failing big time. I have a 2021 2500. I've download the OBD Wiz also and everything shows up fine with no issues. Alfa says its connected but when I try to do anything it's not getting through. I can't even do a simple turn signal or fog light test. I've been trying to do stop the fog light drop out with the high beams and thats not taking. I am getting the following messages. Any thoughts or suggestions would be appreciated.
