Restore Your Cadillac’s Brain and Banish Electrical Gremlins for Good
Is your 2015 Cadillac Escalade ESV acting possessed? Flickering lights, malfunctioning power windows, a dashboard lit up with random warnings, or worse, a no-start condition? Before you resign yourself to a costly and time-consuming trip to the dealership, understand that the culprit is likely a failing Body Control Module (BCM). As an automotive diagnostician with over two decades of experience, I’ve seen firsthand how a faulty BCM can turn a luxury vehicle into a source of immense frustration. It’s the central hub for all your vehicle’s body electronics, and when it fails, chaos ensues.
This isn’t just a replacement part; it’s a complete, hassle-free solution. We offer a professional cloning service for the BCM, part number 13594692 (interchangeable with 13580690 and others). You simply send us your original BCM, and we transfer all its critical data—including VIN, key information, and vehicle-specific options—to this fully tested replacement unit. The result? A true plug-and-play module that requires no additional programming or dealer intervention upon installation. You get your Escalade back to factory-fresh functionality without the dealership price tag.
From the Diagnostic Bay: The Case of the Phantom Drain
A customer brought in a 2015 Sierra with a battery that would die overnight. They’d already replaced the battery and alternator. After hooking up my ammeter, I saw a significant parasitic draw. The tedious process began: pulling fuses one by one. The draw dropped when I pulled the BCM fuse. A failing BCM was keeping other modules awake long after the key was off, slowly draining the life out of the battery. A cloned BCM like this one solved the problem instantly, saving the customer from replacing more unnecessary parts. This is a classic BCM failure scenario I’ve diagnosed hundreds of times.
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 solution:
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ Horn honking randomly or not working at all.
- ✔ Intermittent no-start or security system issues.
- ✔ Multiple, unrelated warning lights on the instrument cluster (e.g., Service StabiliTrak, Airbag, etc.).
- ✔ Communication error codes, such as U0140 (Lost Communication With Body Control Module).
- ✔ Wipers or radio turning on and off by themselves.
Your Simple Mail-In & Installation Process
Getting your vehicle back on the road is straightforward. Our process eliminates the need for complex programming tools.
- Step 1: Place Your Order. After you purchase, we will contact you with detailed instructions and the shipping address to send your original BCM.
- Step 2: Remove Your Original BCM. On most 2015 Escalade ESV models, the BCM is located under the steering column. Carefully disconnect the negative battery terminal, then locate and unplug the electrical connectors from the module and remove it from its bracket.
- Step 3: Ship Your Module. Securely package your original BCM and ship it to us. Once we receive it, our technicians will perform the data cloning service within 1-2 business days.
- Step 4: Install the Replacement. We’ll ship your new, pre-programmed BCM back to you. Installation is the reverse of removal. Reconnect the module, re-attach the negative battery terminal, and start your vehicle.
Important Post-Installation Notes
While our goal is a seamless plug-and-play experience, some GM vehicles may require a simple relearn procedure to sync all systems perfectly. These typically require a professional-grade scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the airbag system.
- Brake Pedal Position Relearn: To ensure correct brake light operation and traction control performance, a recalibration of the brake pedal position sensor may be necessary.
Disclaimer: Always consult a factory service manual or a qualified technician if you are unsure about any step. No core charge is required; you can keep your original module.

Frequently Asked Questions
What exactly is a ‘cloning’ service?
Cloning is the process of reading all the essential, vehicle-specific data (like VIN, mileage, security keys, and optional features) from your original BCM and writing it directly onto the replacement module. This makes the new module an exact digital copy, ensuring it works perfectly with your vehicle’s other computers without needing a trip to the dealer for programming.
Do I need to send my original BCM?
Yes. This service requires your original module to perform the data transfer. After you place your order, we will provide you with shipping instructions. This is how we guarantee a plug-and-play installation.
Will this fix my specific electrical problem?
This BCM is the solution for a wide range of common electrical issues listed in the symptoms section. If your mechanic has diagnosed a faulty BCM, or if your vehicle displays multiple symptoms from our list, this is very likely the correct fix.
Is there a core charge?
No, there is no core charge. After we clone the data, you are not required to send the replacement module back. You can keep your original part.
What if the airbag light comes on after I install it?
This is a known possibility on some GM vehicles. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag module (SDM). A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
How long does the whole process take?
Once we receive your original module, our cloning service typically takes 1-2 business days. The total time will depend on shipping times to and from our facility. We provide tracking information for the return shipment.
