Restore Full Functionality to Your GM Vehicle
Are you dealing with bizarre electrical issues in your 2015 GMC Yukon or another compatible GM vehicle? Flickering lights, malfunctioning power windows, a security system that acts up, or even a vehicle that won’t start can all point to a single, central culprit: a failing Body Control Module (BCM). As the nerve center for your vehicle’s body electronics, a faulty BCM can create a cascade of frustrating and seemingly unrelated problems. In my 20+ years of hands-on diagnostics, I’ve seen how a bad BCM can mimic a dozen other issues, leading to wasted time and money on incorrect repairs.
This is your definitive, no-hassle solution. We provide a fully tested, reliable replacement BCM that is professionally programmed with your vehicle’s exact data. Our mail-in cloning service makes this process simple. You send us your original BCM, and we transfer all the critical information—including VIN, mileage, and specific options—to this replacement unit. The result? A true plug-and-play module that restores your vehicle’s functions without requiring expensive dealership programming or security relearn procedures. This is the most efficient way to get a reliable fix for your 2015 Yukon Body Control Module and get back on the road with confidence.
Case Study: The Ghost in the Sierra
A customer brought in a 2014 Sierra 1500 with a laundry list of complaints: the radio would randomly shut off, the dome light wouldn’t work, and the power locks were intermittent. He had already replaced the battery and checked all the fuses. Diagnostics showed a series of communication loss codes (U-codes) with various modules. Instead of chasing each individual symptom, experience pointed me directly to the BCM. We performed our cloning service onto a replacement module, and upon reinstallation, every single electrical gremlin vanished. It’s a classic example of how a central component failure can manifest in widespread, confusing ways.
Is Your Vehicle Showing These BCM Failure Signs?
A failing BCM can be tricky to diagnose because its symptoms often overlap with other component failures. If you’re experiencing any of the following, your BCM is a likely suspect. Pay close attention to communication Diagnostic Trouble Codes (DTCs), as they are a strong indicator.
- ✔ Erratic or non-functional interior/exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors not working or operating intermittently.
- ✔ The security system or keyless entry is malfunctioning, or the car alarm goes off randomly.
- ✔ The instrument cluster displays incorrect information or gauges behave erratically.
- ✔ The vehicle won’t start, but the battery and starter are confirmed to be good.
- ✔ The radio or infotainment system randomly turns on or off.
- ✔ Stored DTCs such as U0140, U0155, or other ‘U’ codes indicating loss of communication with the BCM.
A Straightforward Guide to BCM Installation
Installing your newly programmed 2015 Yukon Body Control Module is a manageable job for a DIYer with basic tools. The BCM is typically located under the driver’s side of the dashboard. Always consult a service manual for your specific vehicle’s location and torque specs.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow all systems to power down completely.
- Locate the BCM: On most trucks and SUVs like the Yukon and Sierra, you’ll find the BCM under the steering column, often behind a lower dash panel. You may need to remove this panel for access.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount the replacement BCM onto the bracket and securely fasten it. Reconnect all electrical connectors, ensuring each one clicks firmly into place.
- Reconnect Power: Reattach the negative battery terminal.
- Test and Verify: Turn the key to the ‘On’ position and test all body functions: lights, windows, locks, wipers, and radio. Start the vehicle and check for any warning lights on the dash.
Important Post-Installation Notes
While our programming service makes this a plug-and-play repair, some vehicle systems may require a quick sync-up. If you see an airbag warning light, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, some models may require a ‘Brake Pedal Position Relearn’ for optimal traction control performance. These are not always necessary but are important to be aware of.

Frequently Asked Questions About Our BCM Service
How does the mail-in programming service work?
It’s simple. After you purchase, we will contact you with instructions to ship your original BCM to our facility. Once we receive it, our technicians will extract the necessary data and transfer it to your new module. We then ship the programmed, ready-to-install BCM back to you with tracking information.
Do I need to send my keys with the BCM?
No, you do not need to send your keys. All the necessary security and key information is stored within the BCM itself, which we will transfer during the cloning process.
What if my original BCM is completely dead or can’t be read?
In most cases, even with significant internal failure, we can still retrieve the essential data. If your module has suffered extreme damage (e.g., fire or severe water intrusion) that makes it unreadable, we will contact you to discuss alternative solutions, which may involve sourcing data from another module in your vehicle.
Is any additional programming needed after I install it?
Our goal is a 100% plug-and-play solution. Over 95% of installations require no further steps. However, as mentioned, some GM vehicles may require a simple ‘SDM Key Setup’ or ‘Brake Pedal Position Relearn’ with a scan tool if specific warning lights appear. This is a quick procedure for any professional shop.
Do I have to return my old BCM? Is there a core charge?
No. There is absolutely no core charge for this part. You only need to send us your original BCM for the data transfer service. You can keep your old module afterward.
