This genuine GM BCM, part number 15284816 (interchangeable with 25844480), is the definitive solution for your 2011 Sierra Denali and a wide range of other 2007-2013 GM vehicles.

Solving Electrical Issues with a Pre-Programmed 2011 Sierra Denali BCM
The BCM is the nerve center of your truck’s comfort and convenience features. When it fails, it can make driving an unpredictable experience. Our professionally programmed BCM resolves these issues by restoring stable communication between all related components. We load the latest GM software directly onto the module using your VIN, so it arrives ready to install. This eliminates the need for expensive dealer-specific tools and programming fees. The installation is straightforward, typically located under the driver’s side dash near the steering column, and can be completed in minutes.
Post-Installation Procedures
While this module is designed for plug-and-play installation, some vehicles may require a simple relearn procedure. If you see an airbag light after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function to sync the new BCM with the airbag system. In some cases, a ‘Brake Pedal Position Relearn’ may also be necessary to ensure proper brake light and traction control operation. These are standard procedures that any qualified technician can perform.
Frequently Asked Questions
What does a BCM do on a 2011 GMC Sierra?
The Body Control Module (BCM) acts as the central computer for your truck’s body electronics. It manages functions like power windows, door locks, interior and exterior lighting, the security system, wipers, and HVAC controls.
Is this BCM difficult to install?
No, the physical installation is quite simple. The BCM is typically located under the driver’s side dashboard and can be swapped out in under 15 minutes with basic tools. Because we pre-program it to your VIN, no additional computer setup is required for most functions.
Will I need to take my truck to the dealership after installing this?
Our VIN programming eliminates the need for dealership programming for the module itself. However, if your airbag light remains on, a ‘SDM key update’ procedure may need to be performed with a professional scan tool, which can be done by most independent repair shops.
What does ‘No Core Charge’ mean?
It means you do not have to send your old, faulty BCM back to us. You can keep it or dispose of it yourself, saving you the hassle and expense of return shipping.
How do I know this part will fit my vehicle?
This module fits a wide range of 2007-2013 GM trucks and SUVs, including the Sierra, Silverado, Tahoe, Yukon, and Escalade. We confirm compatibility by programming the module to the VIN you provide at checkout, guaranteeing a perfect electronic match for your specific vehicle.
