Solving Your Truck’s Electrical Headaches for Good
Is your 2007-2010 GMC Sierra Denali acting possessed? One day the power windows don’t work, the next the radio is on the fritz, and the HVAC system has a mind of its own. These frustrating, intermittent electrical problems often point to one culprit: a failing Body Control Module (BCM). The BCM is the electronic nerve center for your truck’s comfort and convenience features. When it fails, it can cause a cascade of issues that are difficult to diagnose. This replacement module, identified by part number 15263497, is the definitive solution to restore order and reliability to your vehicle’s electronics.
We offer a professional Cloning Service with this module. This isn’t just basic VIN programming; we transfer the exact data from your original, faulty BCM directly onto this replacement unit. This ensures that all your vehicle’s specific options, security information, and settings are perfectly preserved. The result is a true plug-and-play installation with no need for expensive dealership programming or complicated relearn procedures. For anyone tackling this job, from a seasoned mechanic to a weekend DIYer, our cloned 2007-2010 Sierra Denali BCM is the most efficient and reliable path to a fully functional truck.
A Technician’s Notebook: The Case of the Wandering Gremlins
I had a 2008 Sierra Denali in my bay that was driving the owner crazy. The symptoms were all over the map: the dome light would flicker, the driver’s side door lock wouldn’t respond, and the airbag light was on with a B1001 code. He’d already replaced the battery and checked the main grounds. After scanning the network, I saw multiple communication errors pointing toward the BCM. Instead of a costly new module and hours of programming at the dealer, we opted for a cloned unit. We transferred his original data, and the installation took less than 10 minutes. Every single issue was resolved instantly. It’s a perfect example of how a failing 2007-2010 Sierra Denali BCM can create a host of seemingly unrelated problems.
Is Your Sierra Plagued by These Electrical Gremlins?
- ✔️ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔️ Interior or exterior lights flickering, staying on, or refusing to turn on.
- ✔️ The security system acting up, causing no-start conditions or false alarms.
- ✔️ HVAC controls are unresponsive, or the blower motor works sporadically.
- ✔️ An airbag warning light is illuminated, often with DTC B1001 (Setup SDM Primary Key in BCM).
- ✔️ Unexplained battery drain when the vehicle is off.
- ✔️ Various communication DTCs (U-codes) stored in the system.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your truck’s battery before beginning any electrical work.
- ✔ Locate the BCM: The Body Control Module is typically found under the driver’s side dashboard, to the left of the steering column. You may need to remove a lower dash panel for access.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be pressed. Once disconnected, remove the screws or bolts holding the module in place.
- ✔ Install the New Module: Mount your new, cloned BCM in the same position and secure it. Reconnect all electrical connectors, ensuring they click firmly into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all functions: windows, locks, lights, wipers, and HVAC to confirm the repair is successful.
- ✔ Post-Install Checks: In some cases, an Airbag System Sync or Brake Pedal Position Relearn may be needed. Please see our FAQ for more details on these simple procedures.

Frequently Asked Questions
What is a ‘Cloning Service’ and how does it work?
Cloning is a service where we transfer the complete software and vehicle-specific data from your original BCM to the replacement unit. You send us your old module, we perform the data transfer, and then we ship both the new, ready-to-install module and your original module back to you. This ensures 100% correct functionality for all your truck’s options.
Will this fix my airbag light that is on?
Often, yes. A faulty BCM is a common cause of the airbag light, especially with code B1001. After installing our cloned module, if the light remains, you may need a technician to perform the ‘Setup SDM Primary Key in BCM’ procedure with a diagnostic tool to sync the systems.
Is this part difficult to install myself?
No, the physical installation is very straightforward for most DIYers. It’s located under the dashboard and is typically held in by a few screws or clips. Since our module is cloned, there is no complex computer programming required, making it a simple swap.
Do you keep my old BCM? Is there a core charge?
No. There is no core charge for this part. We always return your original module to you along with the newly cloned replacement.
What other part numbers is this compatible with?
This module is a direct replacement for part number 15263497 and is also interchangeable with the following: 25835966, 15263363, 15878753, 15284816, 15943678, 25844480, 20939137, 22860591, and more.
