2013 Dodge Ram 2500 OEM Trailer Brake Controller Does Not Lock Brakes on One Trailer

Question

Question:

I am having a problem with communication between a 2013 Dodge Ram 2500 OEM Trailer Brake Controller evic and a flatbed trailer with brakes on one axle. For reference, this controller works just great with the travel trailer so I dont suspect a controller issue however it does not work with the flatbed. I have checked the wiring 7pin and tested the operation of all lights and trailer brakes when removed from the truck and all is well. I have tested the connection by connecting the trailer to another truck and the brakes lock up just fine. Therefore the conclusion is that the truck controller works with other trailers, and the trailer works fine with other trucks, but the two of them wont work with each other. As I said, the wiring has all been tested but what we cannot identify is how the Dodge system senses the trailer or why the EVIC says trailer not connected when it clearly is. Does the new Dodge have a non-standard pinout? I have had this checked out by three people and reached the same conclusion that everything SHOULD be working... but it does not.

The OEM brake controllers manufacturers have been putting in trucks have some interesting quirks. First, if the trailer using an electric over hydraulic braking system then that is probably the issue. Factory controllers are notorious for not working with EOH systems. Some EOH actuators do have an adapter you can use but I would need to know the actuator manufacturer.

Another possible issue is that the gain is not turned up enough to work properly with that one trailer. All trailers are different and you may just need to turn up the power output to get it going, or stopping in this case, properly.

You can test the magnets to see if they are working properly but if the trailer works fine with other trucks I doubt this is the issue. Still it might be worth checking out. I have included a link to an article that explains how to test the magnets.

If all else fails you could install an aftermarket controller in place of the factory one. I have linked another Tech Bulletin that covers this because there are some subtleties with your generation Ram and the factory controller.
