Is Your GM Truck or SUV Plagued by Baffling Electrical Problems?
Flickering lights, malfunctioning power windows and locks, strange warning messages, or a vehicle that refuses to start can all point to one culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause widespread and frustrating issues. For owners of powerful trucks like the Sierra Denali, this isn’t just an inconvenience—it’s a compromise on the vehicle’s capability and your confidence. This pre-programmed BCM is the definitive, hassle-free solution to restore your vehicle’s electrical integrity and get you back in command.
Common Symptoms & Your Solution
If you’re experiencing any of the following, a faulty BCM is the likely cause:
- Interior or exterior lights behaving erratically or not working at all.
- Power windows, door locks, or mirrors operating intermittently or failing completely.
- The security system acting up, causing alarm or starting issues.
- Warning lights on the dash with no apparent cause.
- Communication error codes (U-codes) stored in the system.
Our professional cloning service makes replacement simple. You send us your original BCM, and we transfer its unique data—including VIN, mileage, and security information—to this fully tested replacement unit. The result is a true plug-and-play module, eliminating the need for expensive and time-consuming programming at a dealership. This is the most efficient way to install a replacement 2015 Sierra 2500 BCM 13587704 and restore perfect functionality.

Expert Insight: The Power of Cloning
Why is our cloning service superior to buying a used BCM from a salvage yard? A standard used BCM contains the data from its donor vehicle. Installing it in your truck will cause an immediate mismatch of VIN and security information, preventing the vehicle from starting and functioning correctly. Our cloning process treats the replacement module like a blank slate, precisely transferring your vehicle’s unique “digital DNA.” This preserves all factory settings and security handshakes between modules, ensuring a seamless and correct integration that a non-programmed part can never achieve.
Important Post-Installation Notes
While our programming makes the 2015 Sierra 2500 BCM 13587704 a plug-and-play solution, some vehicle systems may require a simple relearn procedure to fully sync after installation. These do not require a trip to the dealer and can often be performed with high-level diagnostic tools found at most independent repair shops.
- Airbag System Sync: If the airbag warning light is on after installation, a “Setup SDM Primary Key in BCM” procedure is necessary to sync the systems.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be needed on some models to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
Frequently Asked Questions
How does this programming service work?
It’s simple. After you place your order, we will contact you with instructions to ship your original BCM to our facility. Once we receive it, our technicians will clone the data to the replacement module and ship it back to you, typically within 1-2 business days. You will receive tracking information once it’s on its way.
Is this BCM truly “plug and play”?
Yes, for over 99% of installations. Because we transfer all the critical data from your original unit, no dealership programming is required for the vehicle to start and run. In some rare cases, as noted above, a simple relearn procedure for systems like the airbag or brake pedal sensor may be needed.
What happens if I have an airbag light after installation?
This is a known possibility on some GM platforms. It simply means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A procedure called “Setup SDM Primary Key in BCM” using a professional scan tool will resolve this and turn off the light.
How long does the entire process take?
Our in-house cloning service is completed within 1-2 business days of us receiving your original module. The total time will depend on the shipping transit times to and from our facility.
Will this fix my specific problem?
This programmed 2015 Sierra 2500 BCM 13587704 will correct issues directly caused by a faulty Body Control Module. We always recommend having a qualified technician perform a complete vehicle diagnosis to confirm the BCM is the root cause of your problems before ordering.
What part numbers does this BCM replace?
This module is a direct replacement for the following part numbers: 13592137, 13506935, 13506936, 13587704, and 13594764. Please ensure one of these numbers matches the part you are replacing.
