Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution
Are you dealing with baffling electrical issues in your Cadillac, Chevy, or GMC? Flickering lights, malfunctioning power windows, or a security system that has a mind of its own are classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can create a cascade of frustrating and unpredictable problems. This isn’t just an inconvenience; it can affect vehicle safety and security. We offer a reliable, straightforward fix with this professionally programmed 2015-2016 CTS BCM, a direct replacement for part number 13594764 and other compatible numbers.
Forget expensive dealership visits that involve high labor costs and complex programming appointments. Our unique cloning service simplifies the entire process. You send us your original BCM, and we transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to this replacement unit. The module you receive back is a true plug-and-play part, ready for installation right out of the box. This saves you time, money, and the headache of needing specialized scan tools for setup.
From the Diagnostic Bay: The Ghost in the Cadillac
A few months back, a 2015 Cadillac CTS came into my shop with a list of complaints that sounded like something from a horror movie. The owner said the interior lights would pulse randomly, the radio would shut off, and sometimes the driver’s side window wouldn’t respond. He’d been to two other shops that couldn’t find the issue because it was so intermittent. After checking the basics—battery, alternator, and ground connections—we hooked up our professional diagnostic scanner. We found a slew of communication error codes (U-codes) pointing to a network problem. The common link? The BCM. After swapping in a cloned module like this one, every single one of the ghostly electrical problems vanished. It’s a perfect example of how a failing 2015-2016 CTS BCM can wreak havoc in ways that seem unrelated.
Is Your Vehicle Showing These Symptoms?
- ✔️ Erratic or non-functional interior and exterior lights.
- ✔️ Power windows, locks, or mirrors working intermittently or not at all.
- ✔️ The security system or keyless entry is malfunctioning.
- ✔️ Warning lights on the dashboard appear for no reason.
- ✔️ Communication error codes (DTCs) like U0140, U0155, or other U-series codes are present.
- ✔️ The engine won’t start due to a security system immobilizer issue linked to the BCM.

Post-Installation Checks
While our goal is a seamless installation, some modern vehicles require a final handshake between modules. Be aware of these potential, but not always necessary, procedures:
- Airbag System Sync: If the airbag light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system to the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure brake lights and traction control function correctly.
Please Note: We offer a no-hassle service with no core charge. You can keep your original module.

Frequently Asked Questions
How does the mail-in programming service work?
After you place your order, we’ll email you instructions. You’ll ship your original BCM to us. We then copy the essential data from your module to the replacement one and ship it back to you, ready for installation.
Is this truly plug-and-play?
Yes. Because we clone your vehicle’s original data, the replacement module will be recognized by your car’s computer system without needing any additional programming or trips to the dealer.
What if my original BCM is completely dead or not communicating?
In many cases, even if the module is failing, we can still extract the necessary data. If we are unable to retrieve the data, we will contact you to discuss options or provide a full refund.
Do I need to send my keys?
No, you do not need to send your keys. All the necessary security information is stored within the BCM itself, and our cloning process transfers it directly.
How long does the whole process take?
We typically program and ship the module within 24-48 hours of receiving your original unit. The total turnaround time will depend on shipping speeds to and from our facility.
Is there a core charge?
No, there is no core charge for this service. You are free to keep your original module after the service is complete.
