Tired of Bizarre Electrical Problems in Your GM Vehicle?
If your 2015 GMC Yukon XL 1500 is acting possessed—with flickering lights, malfunctioning power windows or locks, a dead instrument cluster, or random security alerts that prevent it from starting—you’re likely dealing with a failed Body Control Module (BCM). As the central computer for your vehicle’s comfort and convenience features, a faulty BCM can turn your daily drive into a frustrating guessing game. In my 20+ years as a technician, I’ve seen these modules cause some of the most confusing symptoms, often leading owners to replace perfectly good parts before landing on the real culprit.
This isn’t just a replacement part; it’s a complete, hassle-free solution. We offer a pre-programmed BCM that is a direct, plug-and-play fix. By using our simple mail-in cloning service, we transfer all the critical data from your original BCM to this fully tested replacement unit. This means no expensive trips to the dealership for programming, no key relearn procedures, and no compatibility headaches. You get a module that is ready to install right out of the box, restoring full functionality to your vehicle.
A Technician’s Notebook: The Intermittent No-Start
I once had a 2015 Sierra 1500 in the bay with an intermittent no-start condition that was driving the owner crazy. The battery was new, the starter tested fine, and there were no engine codes. However, scanning the network, I found a slew of U-codes (communication errors) pointing to the BCM. The tell-tale sign was that the power door locks would stop working at the same time the no-start occurred. The BCM was intermittently dropping off the data bus, taking the security authentication with it. A cloned BCM solved all the issues at once, saving the customer hundreds compared to a dealership diagnosis and programming fee.
Is Your Vehicle Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system light is on, and the engine won’t crank (anti-theft active).
- ✔ The instrument panel gauges are dead or behave strangely.
- ✔ The radio or infotainment system is unresponsive.
- ✔ Diagnostic trouble codes (DTCs) like U0140, U0155, B1001, or other communication-related faults are present.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On most compatible trucks and SUVs like the 2015 Yukon XL 1500, the BCM is located under the driver’s side of the dashboard, near the steering column. On other models (like the Corvette or CTS), it may be in the LH dash area or on the firewall.
- ✔ Remove Your Original BCM: Carefully disconnect the electrical connectors. They have locking tabs that must be pressed to release. Unbolt or unclip the module from its mounting bracket.
- ✔ Ship Us Your Module: After purchase, we will provide you with detailed instructions and a shipping address. Package your original BCM securely and send it to us.
- ✔ Install the Cloned BCM: Once you receive the programmed replacement from us, simply plug in the connectors and mount it in the original location. Reconnect your battery.
- ✔ Post-Installation Checks: Start the vehicle and test all body functions—lights, locks, windows, etc. In some cases, additional relearn procedures may be needed.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be required to ensure correct brake light and traction control operation.

Frequently Asked Questions
How does the mail-in cloning 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 its programming to the replacement module and ship it back to you, usually within 1-2 business days. This makes the new part ready for installation without any extra programming.
Do I need to send my keys?
No, you do not need to send your keys. Because we are cloning your original module’s data, the replacement BCM will already recognize your existing keys, saving you time and money.
What if my original BCM is completely dead or not communicating?
In most cases, even if the BCM is failing, we can still extract the necessary data. If your module has severe water or fire damage, please contact us before ordering to discuss options.
Is this a plug-and-play part?
Yes, because we clone your original data, the replacement BCM is plug-and-play. However, as noted, some models may require a simple airbag or brake pedal position relearn procedure with a scan tool if specific warning lights appear after installation.
Is there a core charge for this 2015 Yukon XL 1500 BCM?
No, there is no core charge. You are required to send your original module to us for the data cloning service, but you do not need to return it afterward. Keep your original module.
