How to Clear Toyota Tundra Display Error Code After Installing Primus IQ Brake Controller

Question:

I have a 2016 Toyota tundra that has a factory intergraded controller in it. I had issues with it braking trailer. I took to dealer they couldnt find any issues but when braking with 12 volt light connected to braking wire at trailer the light goes on for a 2 seconds then goes half a lite. But when you use the manual slide knobs it shows that its working just fine. So, I bought Tekonsha 90160 with 3031-P wiring harness. I unconnected the factory controller and plugged in the new controller. The truck came up with an trailer brake error on display screen, but brake controller seems to work without any issues. Is there a way to get rid of the error? Also when brake pedal is pressed the light goes Brite then dim then Brite again is this normal for you brake controller?
