Understanding the 2014 GMC Sierra 1500 Trailer Brake System
The trailer brake system in your 2014 GMC Sierra 1500 is designed to work in conjunction with your truck’s brakes, providing additional stopping power when towing.

A faulty brake controller is another potential issue. The controller manages the electrical signal sent to the trailer brakes. If it malfunctions, the warning light may illuminate. Additionally, problems with the trailer’s brakes themselves, such as worn brake shoes or a malfunctioning actuator, can trigger the warning light on your truck.
Diagnosing the Problem
Start your diagnosis by inspecting the 7-pin connector. Look for any signs of damage, corrosion, or loose connections. Cleaning the connector with electrical contact cleaner can often resolve the issue. Next, test the trailer brakes with a separate tester.
