An Expert’s Take: As a mechanic, I’ve seen firsthand what happens when a TBCM fails. It’s not just an inconvenience; it’s a major safety liability. On a heavy-duty truck like a Silverado or Sierra, the trailer brakes do a significant amount of work. Without them, your truck’s brakes are overworked, stopping distances increase dramatically, and you risk dangerous trailer sway during hard braking. Installing a properly programmed module isn’t just about clearing a light on the dash—it’s about ensuring you have full control over your load, protecting your investment and, most importantly, keeping everyone on the road safe.

Frequently Asked Questions
Why does this module need to be programmed to my VIN?
Modern vehicles use specific software for their electronic modules. Programming the TBCM to your Vehicle Identification Number (VIN) ensures it communicates perfectly with your truck’s other computers, like the BCM and ECM, for flawless operation and compatibility.
Where is the Trailer Brake Control Module located on my truck?
On the specified 2007-2009 GM trucks, the TBCM is typically located on the driver’s side (LH) frame rail, towards the rear of the vehicle. It’s exposed to the elements, which is often a cause of its failure.
Will this part fix the “Service Trailer Brake System” message?
Yes, in the vast majority of cases, a failing TBCM is the direct cause of this warning message. Replacing it with our pre-programmed unit is the correct and reliable solution to clear the warning and restore system functionality.
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit VIN. We will program the module before shipping it to you, making the process as easy as possible.
Is this compatible with other part numbers?
Absolutely. This module is a direct replacement for several part numbers, including 20850923, 25854535, 25788981, and 25907533. If your original part has one of these numbers, this unit will fit and function correctly.
What if I install it and still have issues?
While this module is the most common fix, it’s always wise to check the wiring harness and connectors for corrosion or damage, especially given its location. If you still have problems, remember that this unit is backed by our one-year replacement warranty.
