Restore Full Functionality to Your GM Vehicle
Are you dealing with baffling electrical issues in your 2015 GMC Yukon or other compatible GM vehicle? Flickering lights, unresponsive power windows, a security system that acts on its own, or a dashboard lit up with warning lights are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can create a cascade of frustrating and unpredictable problems. This isn’t just an annoyance; it can affect the safety and reliability of your vehicle.
We offer a straightforward and reliable solution. This is a replacement BCM that comes fully programmed by cloning the data from your original module. This process ensures a seamless, plug-and-play installation, eliminating the need for expensive dealership programming or specialized diagnostic tools. Simply send us your original BCM, and we’ll handle the rest, getting you back on the road with confidence.
From the Diagnostic Bay: The Case of the Haunted Sierra
A customer brought in a 2015 Sierra 1500 with a list of complaints that sounded like something from a ghost story. The horn would blare randomly, the interior lights would flicker at night, and the driver’s side window had a mind of its own. He’d already replaced the battery and checked all the grounds. After connecting my scan tool, I saw a slew of communication error codes (U-codes) pointing to the BCM. These modules are the traffic cops for vehicle data, and when they start failing internally, the signals get crossed, leading to chaos. By providing a cloned 2015 Yukon BCM (the same part family), we restored order to the truck’s network, solving all the spooky symptoms in one go. This mail-in service is the exact solution we use in the shop to save our customers hundreds compared to a dealer visit.
Common Signs of a Failing BCM
If you’re experiencing any of the following, a faulty BCM is the likely culprit. A failing module can also trigger Diagnostic Trouble Codes (DTCs) like U0140, B1001, or other communication-related faults.
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security or anti-theft system prevents the vehicle from starting.
- ✔ The horn honks unexpectedly or the wipers activate on their own.
- ✔ Inaccurate gauge readings or a dashboard that lights up with multiple warning indicators.
- ✔ Complete loss of communication with other vehicle modules, leading to a no-start condition.
A Straightforward Guide to Installation
Our cloning service makes the physical replacement simple. After you receive your programmed module from us, follow these general steps. The BCM location varies, so confirm its position for your specific model (often under the steering column or in the driver-side dash).
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the system to fully discharge.
- Locate the Original BCM: Find the BCM in your vehicle. Its location is noted in the fitment list below.
- Disconnect and Remove: Carefully unplug all electrical connectors from the module. Then, unbolt or unclip the BCM from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Final Checks: Start the vehicle and test all body functions—lights, locks, windows, horn, etc. Note the post-installation procedures below, as some vehicles may require an additional relearn process.
Important Post-Installation Notes
While our programming handles the critical data transfer, some vehicle systems may require a final handshake after installation:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be required to ensure proper brake light and traction control operation.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a qualified professional if you are unsure about any step.

Frequently Asked Questions
How does the programming service work?
After you place your order, we will contact you with instructions to ship your original BCM to us. Once we receive it, we transfer all the necessary vehicle-specific data to the replacement module. We then ship the plug-and-play replacement back to you.
Do I need to get this programmed by a dealer?
No. Our cloning service makes this module 100% plug-and-play. This saves you the time, cost, and hassle of a dealership visit for programming.
Is there a core charge?
No, there is no core charge. We only need your original module to perform the data cloning service. You can keep your original module after the service is complete if you wish.
What tools do I need for installation?
For most models, you will only need basic hand tools like a socket set or screwdriver to access and remove the BCM. No special electronic tools are required for the installation itself.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is failing, the core data on the memory chip is still readable. Please contact us with your specific situation, and our technicians can advise on the likelihood of a successful data transfer.
Will this fix my specific problem?
This part is a solution for issues directly caused by a faulty BCM. If you’re seeing symptoms like erratic lights, lock, and window operation, or communication DTCs, this is very likely the correct fix. Proper diagnosis is key.
