Brakes on Trailer

[Warner52US]

I have a 1989 Nomad Weekender fifth wheel (M1905). My tow vehicle is a 2018 Toyota Tundra with factory tow brakes. While driving to California last summer every now and then I would get an error message on my MID in the dash about the "trailer not connected". This was our first trip with the trailer and tow vehicle combination (previous TV was a 1991 F150 4wd long bed). Do I need to do something different so that I know that my brakes will work on the trailer. The Tundra has 4 wheel Anti Lock Brakes. We had no trouble going down the mountains or stopping. Just annoying to have the message.

Seems to me if I had that problem, I'd start looking at the wires in the trailer female plug, male plug and making absolutely sure the blue wire running to the trailer brakes doesn't have bad splice joints. Then assure yourself that the ground wires are clean and tight.

When it warms up some here, I will check the wires. Didn't know if my brakes on the trailer would or wouldn't work with the ABS. Thanks

If you have an integrated brake controller in your truck or for that matter, a separate brake controller all it does is digitally proportion power to the trailer brake wire Anti Lock Brakes in the truck are not in the equation other than keeping your truck from uncontrolled skidding during hard braking
