@super-dave. I have a 2010 Dodge Ram 1500. Do you know what year of truck this system is on?
You have it. It's called a TIPM or Totally Integrated Power Module. Quite possibly the worst and poorest thought out sytem ever installed on a motor vehicle.
So there is no fuse to protect the lighting. Instead it relies on a PCB to shut down the circuit if it see's a short too often. Then the dealer has to clear the code and restore operation. This can be done up to 3 times before the $1k TIPM must be replaced.
Many people install relays and/or fuses of their own in the circuit to protect the TIPM.
My solution was to by-pass the TIPM all together and run off the vehicle lights, which have a simple fuse we can replace ourselves. Take a simple 12V line testor and see if you have signal on the appropriate spade of the truck mounted 7-pin connector. That will tell you right away whether the problem is on the truck side or the trailer side.
