Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution
Are you dealing with bizarre electrical issues in your 2015 Cadillac XTS or another GM vehicle? Flickering lights, unresponsive power windows, a key fob that works intermittently, or strange warning messages on your dash are classic signs of a failing Body Control Module (BCM). As the central command for your vehicle’s comfort and convenience features, a faulty BCM can make your daily drive incredibly frustrating. In my 20+ years as a technician, I’ve seen how a bad BCM can mimic a dozen other problems, leading to wasted time and money on incorrect diagnoses. This programmed 2015 XTS BCM is the definitive, hassle-free solution.
We take the guesswork and high dealership costs out of the equation. Our professional cloning service transfers the essential data from your original BCM directly to this replacement unit. The result? A module that is 100% plug-and-play. No need for expensive trips to the dealer for programming, no special tools required for setup. You simply send us your original module, and we ship you back a fully programmed replacement, ready for installation right out of the box.
A Technician’s Notebook
I remember a 2015 Sierra 1500 that came into the shop with a laundry list of complaints the owner called “electrical ghosts.” The dome lights would stay on, the radio would randomly shut off, and sometimes the truck wouldn’t even crank. The owner had already replaced the battery and checked the alternator. After hooking up the scan tool, I found a slew of communication codes (U-codes) pointing to the BCM. Instead of a costly new module and hours of programming at the dealer, we used a cloned BCM. The customer mailed us his original module, we programmed the replacement, and he had it back in a few days. He installed it himself in under 30 minutes, and every single issue was resolved. It’s a perfect example of how this service saves drivers time, money, and a massive headache.
Signs Your GM Vehicle’s BCM Is Failing
A failing BCM can cause a wide range of confusing symptoms. If you’re noticing any of the following, your Body Control Module is the likely culprit. This 2015 XTS BCM is designed to resolve these problems.
- ✔ Power windows, locks, or mirrors operate erratically or not at all.
- ✔ Interior or exterior lights flicker, stay on, or won’t turn on.
- ✔ The key fob is unresponsive or works only sporadically.
- ✔ The security system acts up, causing alarm issues or no-start conditions.
- ✔ Wipers behaving unpredictably (e.g., won’t turn off).
- ✔ Multiple warning lights on the instrument cluster with no clear cause.
- ✔ Diagnostic trouble codes (DTCs) related to communication, such as U0140, U0155, or other U-codes.
A Straightforward Guide to Installation
Installing your pre-programmed BCM is a simple process that most DIYers can handle. Here’s a general guide:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: The location varies by model. For the 2015 XTS, it’s typically found at the left front hinge pillar. For trucks like the Sierra or Silverado, it’s often under the steering column. Consult a service manual for your specific vehicle’s location.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be pressed to release. 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. You should hear a click as they lock into place.
- Reconnect the Battery: Reattach the negative battery terminal.
- Perform Relearns (If Necessary): Start the vehicle and check all functions. In some cases, you may need to perform additional procedures. If the airbag light is on, an “Airbag System Sync” is required using a professional scan tool. A “Brake Pedal Position Relearn” may also be needed for proper brake light and traction control operation.
Disclaimer: Vehicle systems can vary. We always recommend consulting a factory service manual or a qualified technician for specific instructions for your make and model.

Frequently Asked Questions
How does the programming service work?
It’s simple. After you purchase, we will contact you with instructions to ship your original BCM to us. Once we receive it, we extract the vehicle-specific data and flash it onto the replacement module. We then ship the plug-and-play replacement back to you.
Do I need to send my original BCM?
Yes, sending your original module is required. This is how we retrieve the unique programming and key data needed to make the replacement module work seamlessly with your vehicle’s security and other systems.
Is this better than buying one from a dealer?
Our service offers a significant advantage. A new BCM from a dealership is a blank slate that requires expensive, time-consuming programming with their proprietary tools. Our cloned module arrives ready to install, saving you hundreds in programming fees and potential towing costs.
What if my old BCM is completely dead?
In most cases, even if the BCM is non-functional in the vehicle, we can still extract the necessary data from the memory chip. Contact us if you have concerns about the condition of your module.
Do I have to return my old BCM after I get the replacement?
No, there is no core charge for this item. After we clone the data, you can keep your original module.
What tools are needed for the post-installation procedures?
The Airbag System Sync and Brake Pedal Position Relearn procedures require a professional-grade bidirectional scan tool. Many local independent shops have this equipment and can perform these calibrations if necessary.
