Restore Safe and Reliable Towing Control
When you’re hauling a heavy load, the last thing you need is a warning light on your dash and uncertainty about your trailer’s brakes. A failing Trailer Brake Control Module (TBCM) can be a major safety concern, compromising your ability to stop effectively. This direct-fit 2011-2012 GM trailer brake control module is the definitive solution to get you back on the road with complete confidence. Unlike salvage yard parts that require expensive dealer programming, this unit arrives at your door pre-programmed to your truck’s specific VIN, ensuring a hassle-free, plug-and-play installation.
Common Symptoms & Your Definitive Solution
If you’re experiencing any of the following issues, a faulty TBCM is the likely culprit:
- The dreaded “Service Trailer Brake System” message on your Driver Information Center (DIC).
- Trailer brakes that don’t engage or work intermittently.
- Diagnostic Trouble Codes (DTCs) such as C0265, C0266, or U0100 stored in your vehicle’s computer.
- A complete lack of output from the manual trailer brake lever.

Expert Insight: The Critical Role of VIN Programming
As a technician, I’ve seen countless truck owners buy a used TBCM from a junkyard, only to find it doesn’t work. Why? Because these modules are not one-size-fits-all. They are programmed to the original vehicle’s specific options (RPO codes). A module from a base model truck won’t work correctly in a Denali, and vice-versa. Our VIN-programming service eliminates this guesswork and frustration. We ensure the 2011-2012 GM trailer brake control module you receive is a perfect electronic match for your vehicle, guaranteeing it functions exactly as the factory intended.
