Trail Brake Module Fault
I got in my truck the other day {2024 F350 with 1000 miles) and when I started it a "Trailer brake module fault" popped up. I press "OK" and it went away but comes up now every time I start it up. The truck runs fine but I also notice now that the blinker lights on the the dash flash really quick like in the old days when a turn bulb was out but the the outside front and rear blinker lights all seem to cycle at normal rate. Any suggestions before I head back to the stealer?

The issue ended up being the connector going to the trailer brake control module (right behind the emergency brake under the dash). It just needed to be re-seated. That also cured the rapid blinking turn signal.
