First time user here. I have a 2022 R18B. Bought a hitch (Texas sidecar) and a trailer later last year. To wire the bike for the trailer I purchased a Hex exCan. Last weekend I went to install this but found I received the wrong kit. But while I had the bike torn down some, I went ahead a change my rear tire. When I got everything back together, I have this Error message. See attached photo. Any ideas? I could reflash the ECU but not sure that will cure it. I have double checked all connections, etc. and all looked good.
