Restore Full Functionality to Your Cadillac with a Hassle-Free BCM Solution
Is your 2015 Cadillac Escalade ESV acting possessed? Flickering lights, malfunctioning power windows, a security system that has a mind of its own, or even a frustrating no-start condition can often be traced back to one component: the Body Control Module (BCM). As an expert technician with over two decades of experience, I’ve seen how a failing BCM can turn a luxury vehicle into a source of constant headaches. It’s the central command for your vehicle’s body electronics, and when it fails, chaos ensues. Don’t let electrical gremlins ruin your driving experience or lead to an expensive and time-consuming visit to the dealership.
This is not just a replacement part; it’s a complete, streamlined solution. We offer a professional cloning service for this BCM, compatible with part number 13594769 and other interchangeable numbers. The process is simple: you purchase this service, ship us your original BCM, and we transfer all of its vital data—including key information, mileage, and vehicle-specific settings—to this fully tested replacement unit. We then ship the programmed module back to you, ready for installation. This means no costly dealer programming, no key relearning procedures, and no compatibility issues. It’s the most efficient way to get your Escalade back to perfect working order.
Case Study: A Tricky Diagnosis
A customer brought in a 2015 Yukon Denali—a close cousin to the Escalade—with a complaint that stumped two other shops: the battery would be dead every morning. They had already replaced the battery and alternator. After connecting my diagnostic tool, I saw no active trouble codes, but I noticed a significant parasitic draw on the electrical system. By pulling fuses one by one, I isolated the draw to the BCM circuit. The BCM wasn’t fully ‘going to sleep’ after the vehicle was turned off, causing a slow drain. A visual inspection of the original BCM revealed no obvious damage, but experience told me it was failing internally. We performed a cloning service just like this one, and the new BCM resolved the parasitic draw instantly. It’s a classic example of how a faulty 2015 Escalade ESV BCM can cause symptoms that aren’t always obvious.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is the likely culprit:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Headlights, taillights, or interior lights staying on, flickering, or not working at all.
- ✔ The security system light is illuminated on the dash, or the alarm goes off randomly.
- ✔ The vehicle won’t start, and you hear a rapid clicking sound (not a dead battery).
- ✔ Climate control system is unresponsive or behaving erratically.
- ✔ Radio or infotainment system issues.
- ✔ Diagnostic trouble codes (DTCs) related to lost communication, such as U0140, U0155, or other U-codes.
Your Straightforward BCM Swap Guide
Installing your pre-programmed BCM is a job most DIY enthusiasts can handle with basic tools. The BCM on the 2015 Escalade ESV is typically located under the steering column, behind the driver’s side lower dash panel.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Access the Module: Carefully remove the lower dash panel beneath the steering wheel to expose the BCM. It’s a black box with several large electrical connectors.
- Disconnect and Remove: Take a photo of the connector positions for reference. Then, carefully release the locking tabs on each electrical connector and unplug them from the old BCM. Unbolt the module from its mounting bracket and remove it.
- Install the New BCM: Mount your new, programmed BCM in the same location. Reconnect all electrical connectors firmly until they click into place.
- Final Steps: Reinstall the lower dash panel. Reconnect the negative battery terminal. Start the vehicle and test all functions—lights, locks, windows, radio, etc.—to confirm the repair.
Post-Installation Checks
Our cloning service makes this a near plug-and-play repair. However, in some GM vehicles, a couple of quick sync procedures may be needed after installation:
- ✔ Airbag System Sync: If the airbag warning light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
- ✔ Brake Pedal Position Relearn: On some models, a brake pedal sensor relearn may be required to ensure brake lights and stability control function correctly. This can also be done with a capable scan tool.
Disclaimer: Always consult a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
How does this cloning service work?
It’s simple. After your purchase, we’ll provide instructions for you to ship your original BCM to us. Once we receive it, our technicians will extract the unique data and transfer it to the replacement module. We then ship the programmed module back to you, ready to install.
Will I need to have my keys reprogrammed?
No. Because we clone the data from your original module, the replacement BCM will recognize your existing keys. This saves you a significant amount of money and hassle compared to buying a blank module from a dealer.
Where is the BCM located on my 2015 Escalade ESV?
The Body Control Module is typically located under the driver’s side of the dashboard, often attached to a bracket beneath the steering column. You will need to remove the lower dash trim panel to access it.
What if my airbag light comes on after installation?
This is uncommon but can happen. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag module (SDM). A repair shop with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Do I need to send my old part back after installation?
No, there is no core charge for this part. You will ship your original BCM to us for the data cloning service, but you do not need to return it after you receive the programmed replacement.
