Display On Pilot Brake Electronic Brake Controller When Trailer Is Not Connected

Question:

I recently install my pilot on a 2014 sierra 5.3. I only get a red dot on the digital display but I have not yet connected a trailer to the truck. Am I supposed to see the gains now or will I need to connect to a trailer to see the digital screen working?

A dot on the screen for your Pilot Brake Controller # 80550 means that the manual slide or the tow vehicle brakes are applied and no trailer is attached and the unit is wired correctly.

If the dot is in the bottom of the screen it is right side up and if the dot is in the top of the screen the unit is upside down. When you connect the trailer you will get a dot and a 'C' in the display. You will then see displays change with numbers when you use the manual slide.
