How do I use my trailer brake controller?
If your vehicle is equipped with the electronic trailer brake controller (TBC) feature, it can help you slow down more safely and smoothly while towing a trailer.
When the TBC is turned on and your trailer is properly connected, the TBC automatically applies brake force to the trailer’s individual wheels when you press the towing vehicle’s brakes.
You can manually adjust the amount of power applied to the trailer brakes, if desired.
