End the Electrical Headaches in Your GM Truck or SUV
Are you dealing with baffling electrical issues in your 2015 Cadillac Escalade? One moment the power windows work, the next they don’t. Perhaps the radio is acting possessed, the security light is flashing, or worse, the vehicle won’t start at all. These aren’t random glitches; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s comfort and convenience features, and when it malfunctions, it can create a cascade of frustrating problems. This isn’t just an inconvenience—it’s a critical failure that can leave you stranded.
We offer a straightforward, reliable solution. This is a replacement BCM, compatible with part number 13591519 and many others, that comes ready for installation through our professional cloning service. You simply send us your original BCM, and we transfer all the essential vehicle-specific data to this replacement unit. The result? A module that is plug-and-play, eliminating the need for expensive dealership visits, towing fees, and complex programming procedures. Get your vehicle’s electronics working flawlessly again.
Common Signs of a Failing BCM
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, your BCM is the likely culprit. I’ve seen these symptoms countless times on vehicles just like yours.
- ✔ Intermittent or non-functional power windows, door locks, and interior lights.
- ✔ Horn honking randomly or not working at all.
- ✔ Erratic instrument cluster behavior, with gauges dropping out or warning lights appearing for no reason (like the security light).
- ✔ Key fob not being recognized, leading to remote start/entry failure.
- ✔ A no-start or no-crank condition, even with a good battery and starter.
- ✔ Communication error codes, such as U0140 (Lost Communication With Body Control Module), stored in other modules.
- ✔ Wipers activating on their own or not turning off.
From the Diagnostic Bay: The Case of the Ghostly Suburban
A customer brought in a 2015 Suburban with a list of complaints that sounded like something from a horror movie. The dash lights would flicker, the radio would change stations on its own, and sometimes it just wouldn’t start. They had already replaced the battery twice. On the scan tool, I found a dozen communication codes pointing everywhere. Instead of chasing each code, I went straight to the source. I checked the data stream from the BCM and found it was dropping out intermittently. This electrical instability was confusing every other module on the network. A new, properly programmed BCM solved every single issue. This is a textbook example of how a failing 2015 Escalade BCM (or one on a similar GM platform) can wreak havoc.
Your Straightforward BCM Installation Guide
Installing your pre-programmed BCM is a manageable task for a DIYer with basic tools. The key is that our cloning service handles the complicated software side for you.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: On most of these GM trucks and SUVs, including 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. Reconnect all electrical harnesses, ensuring each one clicks securely into place.
- Reconnect Power: Re-attach the negative battery terminal.
- Test Functionality: Start the vehicle and test all the features that were previously malfunctioning—windows, locks, lights, radio, etc.
Post-Installation Checks & Procedures
Because our service clones your original data, most vehicles will not require any additional steps. However, in some cases, the following procedures may be necessary:
- Airbag System Sync: If the airbag warning light is illuminated after installation, it means the BCM and the SDM (Sensing and Diagnostic Module) need to be re-synced. A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is only needed if the light is on.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be needed to ensure correct brake light and traction control operation. This can also be performed with a capable scan tool.
Disclaimer: Always refer to a factory service manual for your specific vehicle for detailed instructions and torque specs.

Frequently Asked Questions
Frequently Asked Questions
How does the cloning service work?
After you place your order, we will provide you with instructions to ship your original BCM to us. Once we receive it, our technicians will extract the unique programming and security data and flash it onto the replacement module. We then ship the plug-and-play replacement back to you, typically within 1-2 business days.
Do I need to send my keys with the module?
No, you do not need to send your keys. All the necessary immobilizer and key data is stored within the BCM itself. Our cloning process transfers this information, so your existing keys will work perfectly with the new module upon installation.
Is there a core charge for my old BCM?
No, there is absolutely no core charge. We need your original module to perform the data transfer, but once the service is complete, you can keep your original, non-functional module. We do not require it back.
Will this fix my ‘Service Theft Deterrent System’ message?
In many cases, yes. The BCM is a core component of the vehicle’s anti-theft system. A faulty BCM is a very common cause of this warning message and related starting issues. A correctly programmed replacement BCM will resolve this problem if the module itself is the cause.
What if my original BCM is completely dead or not communicating?
Even if your module is unresponsive, we can often still retrieve the necessary data from the memory chip itself. Please contact us with the specifics of your module’s failure, and our technical team can advise on the likelihood of a successful data recovery.
