Is Your 2015 GM Vehicle Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, malfunctioning power windows, strange warning messages, or even a no-start condition in your 2015 GMC Yukon, Sierra, Chevy Silverado, Tahoe, or other compatible GM model, a failing Body Control Module (BCM) is a likely culprit. The BCM is the central nervous system for your vehicle’s body electronics, managing everything from interior lighting and security to power locks and climate control. When it fails, it can create a cascade of frustrating and seemingly unrelated issues.
From the Diagnostic Bay
We had a 2015 Sierra 1500 in the shop that was driving the owner crazy. The radio would turn on and off by itself, the driver’s side window wouldn’t work, and occasionally the truck would refuse to start, showing a ‘Service Theft Deterrent System’ message. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication loss codes pointing to the BCM. Instead of a costly trip to the dealer for a new module and programming, we used our cloning service. We transferred the data from his faulty BCM to a replacement unit. After a 10-minute install, every single issue was resolved. It’s a perfect example of how a central component failure can mimic a dozen smaller problems.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on.
- ✔ The vehicle’s security system preventing the engine from starting.
- ✔ False warnings on the dashboard instrument cluster (e.g., door ajar, service airbag).
- ✔ Inconsistent operation of the radio, climate controls, or windshield wipers.
- ✔ Rapid battery drain when the vehicle is parked.
- ✔ Communication errors with diagnostic scan tools.

Post-Installation Information
While our goal is a 100% plug-and-play experience, some vehicle systems may require a simple ‘relearn’ or synchronization procedure after the new BCM is installed. These do not require a trip to the dealer and can often be performed with high-level diagnostic tools.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary for proper brake light and traction control functionality.
Please consult a factory service manual or a qualified technician for vehicle-specific procedures.

Frequently Asked Questions
What exactly does the Body Control Module (BCM) do?
The BCM is a computer that acts as a central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and climate controls, ensuring all these components work together correctly.
Why do I need to send you my original BCM?
Your original BCM contains vital security and vehicle-specific configuration data. By cloning this data to the replacement module, we make the new part plug-and-play. This process bypasses the need for expensive and complicated programming at a dealership.
How long does the entire process take?
Once we receive your original module, the cloning process itself typically takes 1-2 business days. The total turnaround time will depend on shipping times to and from our facility. We will provide you with a tracking number as soon as your programmed module is on its way back to you.
Will I need to perform any programming myself?
No, the core programming is completely handled by us. In some cases, as noted above, you may need to perform a simple relearn procedure for the airbag system or brake pedal position sensor if a warning light appears, which can be done with a professional scan tool.
Is this part difficult to install?
For most models like the Yukon and Sierra, the BCM is located under the steering column and is accessible by removing a few trim panels. It is held in by clips or small bolts and has several electrical connectors. Installation is generally straightforward for someone with basic mechanical skills.
