I have a 2020 Silverado 2500 diesel. Have previously successfully used the manual method of "relearning" the trailer tire pressure for my 2 axle Airstream. Recently rotated the trailer tires and needed to again use the manual relearn procedure. This time, while deflating the tires for less than 10 seconds, the truck horn did not signal success and I couldn't tell if the system was working. While retrying the sequence several times, during yet another try, the DIC indicated "Service Trailer Tire Pressure Monitor System" and will not allow me to try again. I set up a new trailer name in the system and was able to relearn all the tires on that "new" trailer so I know the System still works but I can't clear the message to let me complete the process on the original (actual) trailer. My dealer seems clueless about how to simply reset the system. I don't want to delete the existing trailer profile and replace it with my new trailer profile because the original includes maintenance schedule reminders, and trailering MPG, etc. It seems this is just an error condition default message and should be able to be cleared. Ideas?
