Hello all,
I have a TK SB3 Max Plus that will continously blow F21 if the run relay is installed. If I remove the relay the unit boots and shows code 35. I'm completely lost as to where this issue is, I'm not sure if its the relay board or a wiring issue and the trailer is currenlty loaded. I've traced the board out and have not found any shorts, and there are not any shorts in the harness from what I can tell. It was running just fine yesterday.
Thanks
