Is Your GM Truck or SUV Plagued with Electrical Gremlins?
Are you dealing with flickering lights, power windows that have a mind of their own, or a dashboard that lights up with random warnings? These frustrating and often unpredictable issues are hallmark signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, managing everything from the dome light to the security system. When it starts to fail, it can create a cascade of problems that are difficult to diagnose, turning your reliable truck or SUV into a source of constant annoyance.
This genuine GM Body Control Module, interchangeable with part number 15284816, is the definitive solution for restoring your vehicle’s electronic stability. We take the guesswork and high dealership costs out of the equation by pre-programming the module to your vehicle’s specific VIN. This ensures a seamless, plug-and-play installation that gets you back on the road with full functionality restored.
From the Diagnostic Bay
We had a 2009 Silverado 1500 in the shop that was driving its owner crazy. The radio would cut out, the driver’s side window would work intermittently, and the anti-theft light would flash randomly, sometimes preventing the truck from starting. The owner had already replaced the battery and checked fuses with no luck. After hooking up our scanner, we saw multiple communication loss codes with various modules. This pointed us directly to the BCM. Upon inspection under the dash, we found the BCM’s main ground connection was slightly loose and had minor corrosion. While tightening the ground helped, the internal damage to the BCM was already done from the erratic voltage. We installed one of our VIN-programmed modules, ensured all grounds were clean and tight, and every single issue was resolved instantly. It’s a powerful reminder that the BCM is the heart of the vehicle’s comfort and convenience systems.

- ✔ No Core Charge: Keep your old part without any additional fees or the hassle of returning a core.
Installation and Post-Install Procedures
Replacing the BCM is a straightforward process for a DIYer with basic tools. The module is typically located under the driver’s side dashboard, near the steering column.
- Disconnect the Battery: Always disconnect the negative battery terminal before working on any vehicle electronics.
- Locate and Remove the Old BCM: It’s usually held in place by a few small bolts or clips. Carefully disconnect the electrical connectors.
- Install the New BCM: Secure the new module in place and firmly reconnect all electrical harnesses.
- Reconnect the Battery: Reattach the negative battery terminal.
After installation, most functions should work immediately. However, depending on your vehicle’s specific configuration, a couple of additional steps may be required:
- Airbag System Sync: If the airbag warning light remains on, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool and syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: In some cases, the brake pedal position sensor may need to be recalibrated to ensure proper brake light operation and stability control function. This is also performed with a capable scan tool.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM acts as the central computer for your vehicle’s non-engine related functions. It controls the power windows, locks, lights, wipers, security system, climate control, and various other comfort and convenience features.
Why is VIN programming so important for a BCM?
VIN programming loads your vehicle’s specific software and options into the module. Without it, the BCM won’t know how to communicate with other modules, leading to incorrect operation of features or a complete no-start condition. Our service saves you a mandatory and costly trip to the dealership.
Is this BCM difficult to install myself?
The physical installation is typically very simple, often taking less than 15 minutes with basic hand tools. It’s located under the dashboard. However, be aware that post-installation procedures like an airbag system sync may require a professional scan tool.
What happens if my airbag light stays on after installation?
This is normal in some vehicles. It means the new BCM needs to be electronically ‘introduced’ to the airbag module (SDM). A qualified technician with an advanced scan tool can perform the ‘Setup SDM Primary Key in BCM’ function to resolve this.
Do I need to send my old BCM back?
No. This product comes with no core charge. You can keep your original module without any penalty or extra fees.
Will this module fit my 2012 Silverado?
This particular module is specified for vehicles primarily within the 2007-2011 range, though some 2012 and 2013 models may use it. Please verify your vehicle’s compatibility by checking the fitment list on this page or matching one of the interchangeable part numbers to your original module.
