If you have installed the OE trailer wiring module, then yes, try the lights. When the trailer is connected, put it in reverse and see if the rear PDC comes on, or beeps continually. That is the easiest test. However, that module has no brake controller, that is a separate device. A brake controller will be aftermarket by definition, and has no coding.
