An Expert’s Take on BCM Cloning
“In modern trucks like the Sierra Denali, the BCM is far more than a simple fuse box. It’s a sophisticated computer that’s coded specifically to your truck’s VIN and its unique set of optionsโfrom the sound system to the trailer brake controller. A generic, off-the-shelf module simply won’t work correctly. Our cloning process is the gold standard for BCM replacement. We perform a full data transfer from your original unit, which is the only way to ensure every single feature your truck left the factory with works exactly as it should post-installation. It’s the most precise and reliable method available.”
The Simple Mail-In Process
Getting your truck fixed is straightforward. After you place your order, we will contact you with clear, step-by-step instructions for shipping your original BCM to our facility. Our technicians will perform the data transfer to your new 2015 Sierra Denali 2500 BCM replacement and ship it back to you promptly. You’ll receive tracking information so you know exactly when to expect it.
Post-Installation Notes
While this BCM is designed for a plug-and-play installation, some GM vehicles may require a simple relearn procedure for certain systems after the new module is installed. This can include the Airbag System (SDM) or the Brake Pedal Position Sensor. These procedures are typically straightforward and can be performed with a compatible high-level scan tool. Please refer to the provided information regarding potential post-install procedures.
Frequently Asked Questions
What exactly is a BCM cloning service?
This service involves you sending us your original Body Control Module. We then extract the vehicle-specific software, VIN, and security data from it and flash it onto the replacement BCM we provide. This makes the new unit an exact electronic match to your original, ensuring a seamless, plug-and-play installation without the need for dealer programming.
Is the BCM difficult to remove and install?
On most 2015 GM trucks and SUVs, the BCM is located under the steering column or on the driver’s side firewall/hinge pillar. Physical removal and installation typically involve disconnecting the battery and unplugging a few electrical connectors. It is a manageable job for a DIYer with basic tools, but we always recommend consulting a service manual for your specific model.
How long does the programming service take?
Once we receive your original BCM, our technicians typically complete the programming and testing process within 1-2 business days. We then ship the newly programmed module back to you. You will be provided with tracking information as soon as it ships.
Will this fix my truck’s specific electrical problem?
This programmed 2015 Sierra Denali 2500 BCM replacement is the definitive solution for issues directly caused by a failing BCM. If your truck’s symptoms match the ones listed (erratic lights, power accessory failure, security faults), this is very likely the fix you need. However, proper vehicle diagnosis is always recommended to rule out other potential causes like wiring or sensor faults.
Are any extra steps needed after installation?
In some cases, yes. As with any BCM replacement on these vehicles, you may need to perform a ‘Setup SDM Primary Key in BCM’ procedure if the airbag light is on, or a ‘Brake Pedal Position Relearn.’ These procedures require a professional-grade diagnostic tool. Many local repair shops can perform these relearns for you if needed.
Which part numbers does this BCM replace?
This module is a guaranteed compatible replacement for the following GM part numbers: 13592137, 13506935, 13506936, 13587704, and 13594764. Please check your original module to confirm the part number.
