n.c. Flashes on Tekonsha Primus IQ Trailer Brake Controller

Question:

I just bought a Dodge Ram 1500 model 2012. I would like to ask you how the system works, because it doesnt recognize the trailer. There is a manual in Pdf that can i get? Thank you

If the Tekonsha Primus IQ Trailer Brake Controller part # TK90160 shows a flashing ".nc." for 15 seconds this could be caused by a few different things. I have attached these for you below as listed in the owners manual. The controller recognizes the trailer by brake magnet resistance.

1. Trailer not connected to tow vehicle.
2. Trailer connected with open circuit on brake line.
3. Trailer connector disconnected or corroded.
4. Loss of trailer brake magnet ground.

I have attached for you below as well the owners manual for the brake controller.
