Restore Full Electrical Function to Your GM Vehicle
Are you experiencing frustrating and unpredictable electrical problems in your 2015 Cadillac Escalade, Chevy Silverado, or GMC Sierra? Issues like flickering lights, malfunctioning power windows, a dead instrument cluster, or a security system that acts up on its own are often signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing and seemingly unrelated symptoms. Don’t let these electrical gremlins sideline your truck or SUV. We offer a simple, effective, and permanent solution.
The Plug-and-Play Solution: A Programmed 2015 Escalade BCM
Replacing a BCM is not as simple as swapping the part. A new module from the dealership requires expensive and complicated programming to sync it with your vehicle’s specific VIN and security information. Our unique cloning service eliminates this hassle entirely. By purchasing this service, you send us your original BCM. We then expertly transfer all of its critical data—including VIN, mileage, key information, and specific options—to a replacement unit. The module you receive back from us is a true plug-and-play solution. Simply install it, and your vehicle will be back to normal without any need for a trip to the dealer.
From the Diagnostic Bay
We had a 2015 GMC Sierra Denali come into the shop with the most bizarre symptoms. The owner said his radio would randomly turn off, the dome lights would stay on after he locked the doors, and occasionally, the truck wouldn’t start, showing a ‘Service Theft Deterrent System’ message. We checked the battery and alternator, which were fine. After running a full diagnostic scan, we saw multiple communication loss codes with various modules, all pointing back to the BCM. Instead of a costly dealer replacement and programming, we performed a data clone onto a replacement BCM. The customer got his truck back the next day with all issues resolved. It’s a classic case where the central ‘brain’ gets confused, and a direct data transfer is the cleanest, most effective fix.
Common Symptoms of a Failing Body Control Module
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Headlights, taillights, or interior lights behaving erratically (staying on, not turning on, or flickering).
- ✔ The horn sounding randomly or not working at all.
- ✔ Inaccurate or dead gauges on the instrument cluster.
- ✔ ‘Service Theft Deterrent System’ or other security-related warnings on the dash.
- ✔ Key fobs that stop working or work intermittently.
- ✔ Communication errors when a diagnostic scan tool is connected.
- ✔ Parasitic battery drain that kills your battery overnight.

- ✔ We Contact You: We will reach out to you using the contact information on your order to provide shipping instructions for your original BCM.
- ✔ Ship Us Your Module: Carefully package and ship your original BCM to our facility.
- ✔ We Clone Your Data: Upon receipt, our technicians will perform a full data transfer from your original module to the replacement unit. This process typically takes 1-2 business days.
- ✔ Receive Your Ready-to-Install BCM: We ship the programmed replacement BCM back to you. You’ll receive tracking information as soon as it’s on its way. Installation is as simple as removing the old part and plugging in the new one.
Installation and Post-Install Considerations
Installation is straightforward for anyone with basic mechanical skills. The BCM is typically located under the steering column or on the driver’s side firewall. Because we’ve cloned your data, no further programming is needed. However, in some cases, certain systems may need to be re-synced:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be required to ensure proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.

Frequently Asked Questions
What is a BCM cloning service?
It’s a process where we transfer the exact vehicle-specific data (like VIN, mileage, and security info) from your original, failing Body Control Module to a fully functional replacement module. This makes the replacement 100% plug-and-play, avoiding costly dealer programming.
Why is this better than buying a new BCM from a dealer?
A new BCM from a dealer is a blank slate. It requires special tools and subscriptions to program it to your vehicle, a service that can cost hundreds of dollars. Our cloning service bypasses that entire step, saving you significant time and money.
How long does the entire process take?
Once we receive your original module, the cloning process itself typically takes 1-2 business days. The total time will depend on shipping times to and from our facility. We ship the completed module back to you promptly and provide tracking.
Will I need to do any programming after I install it?
No, the module arrives ready for installation. Because we’ve copied all the data from your original part, your vehicle will recognize it as its own. In rare cases, a simple relearn procedure for the airbag or brake pedal sensor might be needed, which can be done with a high-end scan tool.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is not functioning in the vehicle, we can still extract the necessary data from the memory chip. Please contact us before ordering if your module is severely damaged by water or fire.
