I have a 2015 2500 (6.4hemi). I am not getting any voltage to the trailer brakes. It has ITBM. I have checked all fuses under the hood. Do not see or know of any fuses in cab. All lights work perfectly fine and trailer brakes work fine when hooked to other vehicles. (06 2500 and a 20’ 3500 with ITBM). Ground seems to be fine. 12v to the constant power post and charging trailer battery but none on the eletric brake post when manually squeezing or stepping on pedal ( yes the gain has been adjusted from 0-10 and everywhere in between). I have switched from light electric to heavy and even tried the other two options with no change. It doesn’t seem to be recognizing the trailer as dash reads “not connected”. Anybody ran into this? Bad module possibly? Called two dealers with very few ideas on what’s going on and closest one is 1.5 hrs away. I have a gooseneck trailer on that has drum style brakes. Am going to try another trailer tomorrow but I’m positive it’s not the trailer as brakes are working on everything else. Thanks!
