Question:

My curt triflex is throwing up a code. Cant find this code on any curt website. Have had troulbe5with this past two weeks. Dealership that installed it said everything is wired and working correctly. And they will not help me out. I have attached a picture of my controller and the code is more up on it.

The L. display should show up on the Curt TriFlex brake controller, # C24VV, when it is plugged in. When you are installing the controller, the trailer should not be connected.

The lever or button on the left side of the controller is the sensitivity adjustment. The L. should change when that lever is moved. You can also try resetting the controller by unplugging it for a few minutes and then plugging it back in (without the trailer connected). If these things do not fix the issue then there is likely a problem inside the controller and it will need to be replaced.
