I spoke to my contact at Lippert and they informed me that you need to check that you are getting 1.5 to 3 amps coming from the control module. If you are, then test the brake by adding power and ground to the brake leads. (polarity doesn’t matter). I’m suspecting that the brake is bad and not releasing or the brake pad is seized to the pressure plate.

I have attached a wiring diagram for you. Please let me know what you come back with and the part number of your steps if replacement parts are needed.
