My 2012 dash message is saying “trailer brake module fault”. And I have no power to my trailer lights. Anyone know what this means as far a fix is concerned?

 

Use Forscan to check for DTCs. Check for any blown fuses in the fuse panels. Check your dash brake controller for any stuck buttons or loose wiring if you can get to the backside of it.

Couple folks mentioned stuck buttons in the following thread.
