Is Your Truck Experiencing Bizarre Electrical Issues?
When the Body Control Module (BCM) in your 2015 GMC Sierra 2500 begins to fail, it can feel like your truck has a mind of its own. From flickering lights and malfunctioning power windows to no-start conditions, a faulty BCM can bring your workhorse to a grinding halt.

Common Symptoms & Your Solution
If you’re experiencing any of the following, a failing BCM is the likely culprit:
- Power windows, door locks, or interior lights operating erratically or not at all.
- The security system light stays on, preventing the engine from starting.

- Communication error codes (U-codes) stored in the system.

Expert Insight: The End of Dealer Dependency
For years, replacing a BCM meant one thing: an expensive trip to the dealer. Your truck would be towed, you’d pay for the new module, and then you’d pay several hours of labor for a technician to program it with specialized equipment. Your truck could be out of commission for days. Our cloning service changes the game. By perfectly replicating your vehicle’s unique data, we empower you or your trusted mechanic to do the job simply and efficiently. We handle the complex programming so you can handle the straightforward installation, minimizing downtime and getting your truck back to work where it belongs.
Frequently Asked Questions
How exactly does the cloning service work?
After you complete your purchase, we will provide you with instructions for shipping your original BCM to our facility. Once we receive it, our technicians will extract the vehicle-specific data and flash it onto the replacement module. We then ship the ready-to-install unit back to you, typically within 1-2 business days.
Is this module truly plug-and-play?
Yes. Because we transfer all the necessary configuration, VIN, and security data from your original unit, the replacement module will be recognized by your vehicle’s other computers instantly upon installation. No trip to the dealer for programming is needed.
What if the airbag light comes on after installation?
In some cases, the new BCM may need to be synced with the airbag system. If the airbag warning light is on after you install the part, a ‘Setup SDM Primary Key in BCM’ procedure will need to be performed with a professional scan tool. This is a simple relearn procedure that any qualified shop can perform.
Will this 2015 Sierra 2500 Body Control Module 13506936 fix my specific problem?
This module is the definitive solution for issues directly caused by a failing BCM. While it resolves the vast majority of electrical accessory problems, we always recommend a proper diagnosis by a qualified technician to confirm the BCM is the root cause before purchasing.
Do I need to return my old BCM for a core refund?
No. There is no core charge or refund associated with this part. We require your original module only to perform the critical data cloning service. Once the service is complete, we handle the original module for you.
What other vehicles does this part fit?
While this is a perfect match for your Sierra, this BCM also fits a wide range of 2015-2018 GM models including the Silverado, Tahoe, Suburban, Yukon, Escalade, Corvette, Impala, CTS, ATS, and more. Please verify your part number to ensure compatibility.
