Silverado Service Trailer Brake System Fix

This video shows how to correct the annoying "Service Trailer Brake System" message that randomly appears on your dash while driving. The fix is to change the manual trailer brake switch with the updated one (link below). I change the switch in my 2015 Silverado 2500 Duramax. I believe this will work for most 2014-2018 Silverados.
This will also fix the "C1117" code you may have. GM found that the original switches would malfunction and have released a new switch to correct this issue.
Here is the link for the new switch from Amazon Prime:
