Restore Your Vehicle’s Electrical System with an Expert-Programmed BCM
Are you dealing with baffling electrical issues in your 2015 Cadillac Escalade? Intermittent power windows, flickering dash lights, or a security system that has a mind of its own? These are classic signs of a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can turn your luxury SUV into a source of constant frustration. In my 20+ years of automotive diagnostics, I’ve seen how a single failing module can create a cascade of seemingly unrelated problems, making diagnosis a nightmare for the unprepared.
This is not just a part; it’s a comprehensive solution. We offer a replacement BCM compatible with part number 13594768 that is delivered to you fully programmed and ready for installation. Our professional cloning service eliminates the need for expensive dealership visits and complex programming tools. Simply send us your original BCM, and we will expertly transfer all the critical vehicle-specific data—including VIN, mileage, and security information—to this replacement unit. The result is a true plug-and-play module that restores your vehicle’s function seamlessly.
A Technician’s Notebook: The Ghost in the 2015 Tahoe
A customer brought in a 2015 Chevy Tahoe, a vehicle that shares its platform with the Escalade, with a list of bizarre symptoms. The radio would turn on and off, the dome lights would flicker while driving, and occasionally, the vehicle wouldn’t start, with just a click from the starter. They had already replaced the battery and alternator to no avail. After hooking up my scan tool, I found a slew of U-codes (communication errors) pointing to a network problem. Instead of chasing ghosts, I went straight to the BCM. A quick check of the data stream showed erratic voltage readings. We used our cloning service to program a replacement BCM, and the swap took less than 30 minutes. All the ghost-like electrical problems vanished instantly. It’s a perfect example of how the right part, correctly programmed, can save hours of diagnostic headaches and hundreds of dollars.
Is Your Vehicle Exhibiting These BCM Failure Signs?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, your Body Control Module is the likely culprit:
- ✔ Power windows, locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights (headlights, taillights) staying on or not turning on.
- ✔ The anti-theft or security system preventing the car from starting.
- ✔ Dashboard warning lights appearing randomly (e.g., ABS, Airbag, Traction Control).
- ✔ Horn not working or sounding unexpectedly.
- ✔ Communication error codes, particularly U-codes like U0140, U0155, or U0100, stored in the system.
A Straightforward Guide to Your BCM Swap
Our cloning service makes the physical installation simple for both DIYers and professional technicians. Here’s a general overview of the process:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any work on the electrical system.
- Locate the BCM: On most compatible vehicles like the 2015 Escalade, the BCM is located under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors.
- Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions—lights, locks, windows, radio, etc.—to confirm the repair was successful.
Important Post-Installation Note: In some cases, additional steps may be required. For instance, if the airbag light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ might be necessary. Always consult a service manual for vehicle-specific details.

Frequently Asked Questions
How exactly does the programming service work?
It’s simple. After you place your order, we will contact you with instructions 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 plug-and-play BCM back to you, typically within 1-2 business days.
Will I need a mechanic to program or install this BCM?
No programming is required on your end! Because we clone your original module’s data, this BCM will arrive ready to install. Installation is straightforward for a confident DIYer, but you can always have your trusted mechanic perform the swap.
What does the Body Control Module (BCM) actually do?
The BCM is the brain for your vehicle’s comfort and convenience features. It controls non-engine related functions like power windows, interior lighting, door locks, the security system, and even communicates with other modules to ensure everything works in harmony.
Do I need to send my keys along with my old BCM?
No, you do not need to send your keys. All the necessary immobilizer and security data is stored within the BCM itself. By cloning this data, the new module will recognize your existing keys perfectly.
What if the airbag light is on after I install the new BCM?
This can occasionally happen. It requires a simple sync procedure called ‘Setup SDM Primary Key in BCM’ which must be done with a professional-grade scan tool. It’s a quick procedure for any competent repair shop.
Is there a core charge for this part?
No, there is no core charge. We need your original module to perform the cloning service, but you can keep it afterward if you wish.
