Restore Full Electrical Function to Your GMC Truck
Are you chasing down frustrating electrical issues in your 2007-2010 GMC Sierra Denali? Intermittent power windows, a flickering dash, or a security system that acts up on its own are classic signs of a failing Body Control Module (BCM). As the nerve center for your truck’s body electronics, a faulty BCM can cause a cascade of problems that are difficult to diagnose. This module, part number 15284816, is the definitive solution, offered with a professional cloning service that makes replacement easier and more affordable than a trip to the dealership.
Our unique cloning service means you get a module that is a perfect electronic match for your vehicle. We transfer the critical data from your original BCM to this replacement unit. The result is a true plug-and-play component that retains all your truck’s specific settings and security information, eliminating the need for expensive dealer-only programming tools.
Case Study: A Tricky Diagnosis
I remember a 2008 Sierra Denali that came into my shop with a whole list of bizarre symptoms. The radio would turn on and off, the driver’s side window worked only when it wanted to, and the owner was getting a persistent airbag light. He had already replaced the window switch and checked fuses. After connecting my scanner, I saw a handful of communication codes pointing back to the BCM. Instead of just selling him a new module that would need programming, we performed a cloning service. We transferred his original data to the new unit, he installed it in under 10 minutes, and every single issue was resolved instantly. It’s a testament to how a precise, cloned module is often the cleanest fix.
Is Your Sierra Denali Showing These Electrical Gremlins?
- ✔ Unresponsive or erratic power door locks, windows, or mirrors.
- ✔ HVAC blower motor or climate controls not working correctly.
- ✔ An active airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ The anti-theft or security system preventing the truck from starting.
- ✔ Inconsistent operation of interior or exterior lights.
- ✔ Communication errors with other modules on the vehicle’s network.
A Straightforward Guide to Your BCM Swap
- ✔ Step 1: Purchase this BCM cloning service.
- ✔ Step 2: After checkout, you will receive instructions for shipping your original BCM to us.
- ✔ Step 3: Once we receive your module, our technicians will clone all the necessary data to the replacement unit, typically within one business day.
- ✔ Step 4: We ship both your original module and the ready-to-install replacement back to you.
- ✔ Step 5: Installation: Disconnect the negative battery terminal. Locate the BCM under the driver-side dashboard, near the steering column. Carefully unplug the electrical connectors, unbolt the module, and swap in the new one. Reconnect everything and re-attach the battery terminal.
- ✔ Step 6: Post-Install Checks: In some cases, a ‘Setup SDM Primary Key in BCM’ or ‘Brake Pedal Position Relearn’ may be needed if you see a persistent airbag light or brake system warnings. This is done with a professional scan tool and is a simple procedure for any qualified mechanic.

Frequently Asked Questions
What is a BCM cloning service and why do I need it?
Cloning is a process where we transfer the vehicle-specific software, security codes, and option settings from your original BCM to the replacement unit. This makes the new module a perfect electronic duplicate, ensuring it works immediately upon installation without requiring a trip to the dealership for expensive programming.
Do I have to send my original BCM to you?
Yes. For the cloning service to work, we need your original module to extract the data. We will return your original part along with the newly programmed replacement.
Will I need to go to the dealership after installation?
No, our cloning service is designed to eliminate the need for dealer programming. However, as with any major electronic part replacement, some vehicles may require a simple relearn procedure (like for the airbag or brake pedal sensor) that can be performed by any competent mechanic with a professional scan tool.
What if my airbag light is still on after installing the new BCM?
If the airbag light remains on, it typically means the BCM and the Sensing and Diagnostic Module (SDM) need to be re-synchronized. A technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure using a professional diagnostic tool to clear the light.
Is there a core charge for this part?
No, there is no core charge. We always return your original module to you along with the replacement, so you don’t have to worry about core returns or extra fees.
