Trailer issue -2015 chevy 1500 w/ trailer brake

Recommended Posts

Truck randomly "check trailer wiring" followed immediately by "trailer connected"

 

I replaced the trailer side plug first and it made it worse, then I replaced the truck side trailer plug.

 

Hooked it up drove 50ft it threw the dash code. Drove 10 miles to my house. Nothing. Put my rzr on it, threw the message 10 times in a mile. Then it stopped, drove 40 miles absolutely nothing...?

 

Trailer is an older 2002 rice tandem axle trailer.

 

Any ideas?

Thanks, I will try the emery cloth. But they are both brand new plugs.

My message is never about brakes, just wiring

make sure the ground connection on the trailer is good, the reason it will go away and come back is because it is grounding through the ball hitch

Update:
Went under the trailer and wiggled and moved every single wire, it didnt trip this message.

Then when I left with trailer attached BAM it started saying "check trailer wiring... trailer connected".
I have learned its ONLY the brake that messes up. With my lights turned "on" the lights never go away when the truck says that message. Sometimes it will say check trailer wiring and the trailer brake wont work for a minute or two then it will kick back in. BUT while this is happening, the lights still work.

I'm about to replace the trailer battery for electric brakes. It's pretty old.
