Restore Your Yukon’s Electrical System with a Hassle-Free Solution
Are you dealing with baffling electrical issues in your 2015 GMC Yukon or another compatible GM vehicle? Flickering lights, malfunctioning power windows, a radio with a mind of its own, or security system alerts can all point to a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen how a faulty BCM can turn a reliable vehicle into a source of daily frustration. The BCM is the central hub for your vehicle’s body electronics, and when it fails, the symptoms can be widespread and confusing.
This isn’t just a part; it’s a complete service designed to get you back on the road without the exorbitant costs and scheduling nightmares of a dealership visit. We take the complexity out of the repair by cloning the essential data from your original BCM directly onto this replacement unit. This means no need for expensive, specialized programming tools after installation. Simply send us your original module, and we’ll ship this one back, ready to install.
From the Diagnostic Bay: The Case of the Ghostly Yukon
I remember a 2015 Yukon that came into my shop with a laundry list of complaints from the owner. The dash lights would flicker randomly, the driver’s side window would only work intermittently, and the vehicle would occasionally refuse to start, displaying a ‘Service Theft Deterrent System’ message. The owner had already replaced the battery and checked grounds. We scanned it and found a U0140 ‘Lost Communication With Body Control Module’ code. After confirming power and ground to the BCM were solid, we knew the module itself was the culprit. Instead of a costly new unit and hours of programming, a cloned BCM had the truck’s electronics functioning perfectly in under an hour of shop time. This is the exact, reliable fix we offer you.
Is Your GM Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, your Body Control Module is the likely cause:
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The security system acting up, causing no-start conditions.
- ✔ The radio or infotainment system behaving erratically.
- ✔ False warnings appearing on the instrument cluster.
- ✔ Communication-related Diagnostic Trouble Codes (DTCs), such as U0140, U0155, or B1001.
- ✔ Inconsistent horn or wiper operation.
Your Straightforward Installation Guide
Our cloning service makes the physical swap simple. While the BCM location varies slightly by model, the process is generally straightforward for a DIYer with basic tools.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On most trucks and SUVs like the 2015 Yukon, the BCM is located under the steering column, behind the driver’s side lower dash panel. On other models (like the Corvette or ATS), it may be in the LH dash area or on the firewall.
- Remove Trim Panels: Carefully remove any plastic trim or panels necessary to access the BCM.
- Disconnect and Remove: 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 pre-programmed replacement BCM and securely reconnect all electrical connectors. You should hear a click as they lock into place.
- Reconnect and Test: Reinstall any trim panels you removed, reconnect the negative battery terminal, and test all functions—lights, locks, windows, radio, etc.
Important Post-Installation Information
Because your vehicle’s data is cloned, most functions will work immediately. However, for safety systems, some vehicles may require a ‘handshake’ procedure. Please note the following:
- 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 syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light and stability control operation.
- Disclaimer: Always consult a factory service manual for your specific vehicle. If you are unsure about any step, we recommend seeking assistance from a qualified professional mechanic.

Frequently Asked Questions
How does the programming service work?
After you place your order, we will contact you with simple instructions to ship your original BCM to us. Once we receive it, we transfer the necessary data to the replacement BCM and ship it back to you, typically within one business day.
Is this a plug-and-play solution?
Mostly, yes. Our cloning service handles all the critical programming, so you won’t need a trip to the dealer for software flashing. However, as noted, some vehicles may require minor relearn procedures for safety systems like the airbags or brake sensor, which require a professional scan tool.
Do I need to send my keys?
No, you do not need to send your keys. The vehicle’s key and security information is transferred directly from your original module’s data.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is not functioning in the vehicle, we can still extract the necessary data. Please contact us before ordering if your module is severely damaged by water or fire.
Is there a core charge for my old part?
No, there is no core charge. We only need your original module for the data transfer service. You can keep it afterward.
Will this fix my specific problem?
This BCM will resolve issues directly caused by a faulty Body Control Module. While the symptoms we’ve listed are common indicators, proper vehicle diagnosis is always recommended to rule out other potential causes like wiring or sensor faults.
