Ok, I just got my new 2010 Dodge RAM and I just hooked it up to the 5th wheel RV. When I step on the brake, the Dodge brake controller reports "Trailer disconnected". After you let off the brake, I get the message "Trailer Connected".

Now, I don't know if the other truck with the Prodigy(SP?) was doing this or not. That controller was down by my leg, and I didn't look at it that offend. Wife told me that the Prodigy did report an trailer disconnect at least once. So, I figure it more than likely is the trailer.

I did test the Dodge brake controller with a 12 volt light and a volt meter hooked up to the brake wire in the 7 pin plug and everything worked as expected.

So, I have to fix this tomorrow as I'm leaving on a trip Friday afternoon. Does anyone have any suggestions as to what is wrong. The error message does not help me much. Thanks Anthony

 

make sure its plugged in all the way some of the plugs need a good wiggle to get them to work right my 01 does that I just need to give it a good hard push

 

my trailer does this sometimes due to a bad ground.

 

Maybe a little corrosion inside the plug, possible shot of WD40?
