Is Your GM Truck or SUV Experiencing Bizarre Electrical Issues?
If your 2015 Sierra 2500, Silverado, Tahoe, or another compatible GM vehicle is acting possessed, the Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your vehicle’s body electronics, managing everything from your power windows and door locks to the interior lights, security system, and even communication between other critical modules. When it starts to fail, you’ll notice a host of frustrating and seemingly unrelated problems that can be a nightmare to diagnose.
Instead of paying for an expensive new module and dealership programming fees, our professional cloning service provides a simple, cost-effective, and reliable solution. We transfer the unique data from your original BCM directly onto a replacement unit. This process ensures that the replacement module is a perfect electronic match for your vehicle, making installation a true plug-and-play process. No additional programming or calibration is required at the dealership, saving you time and hundreds of dollars.
Common Symptoms of a Failing Sierra 2500 Body Control Module
- ✔ Power windows, mirrors, or door locks working intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system engaging randomly or the vehicle refusing to start due to an anti-theft issue.
- ✔ Dashboard warning lights (like ABS or Airbag) illuminating for no reason.
- ✔ Radio or infotainment system randomly shutting off or behaving erratically.
- ✔ Inaccurate fuel gauge or other instrument cluster malfunctions.
- ✔ Key fob not being recognized by the vehicle.
From the Diagnostic Bay
We had a 2015 GMC Sierra 2500 in the shop that was driving the owner crazy. The horn would honk randomly, the interior dome lights would refuse to turn off, and the driver’s side window would only work when it felt like it. The owner had already replaced the battery and checked all the fuses. After connecting our scan tool, we saw multiple communication error codes pointing towards the BCM. Instead of a trip to the dealer for a new module and a hefty programming bill, we used this exact cloning service. We sent the original module out, got the programmed replacement back, and installed it in under 30 minutes. Every single phantom electrical issue was gone instantly. It’s a game-changer for solving these complex electronic problems.

Important Post-Installation Information
While our goal is a 100% plug-and-play experience, some GM vehicles may require a simple relearn procedure after the new BCM is installed. These are not always necessary but are important to be aware of:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure may be needed. This is a simple task for any shop with a professional-grade diagnostic tool and syncs the BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be required to ensure proper brake light operation and traction control functionality.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, security system, wipers, and the instrument cluster.
Why is cloning my original BCM the best option?
Cloning transfers your vehicle’s exact configuration, including VIN and security data, to the replacement module. This avoids the expensive and complex programming required by a dealership for a brand new BCM, making the installation truly plug-and-play.
How long does the programming service take once you receive my module?
We pride ourselves on a fast turnaround. Typically, the programming and cloning process is completed within 1-2 business days of us receiving your original module. We then ship it back to you promptly.
Will I need to have my keys reprogrammed after installation?
No. Because we clone all the data from your original module, the replacement BCM will recognize your existing keys just like the old one did. This is a major benefit of our service.
What if my original BCM is completely dead or water damaged?
In many cases, even with significant damage, our technicians can still extract the necessary data. Please contact us before ordering if your module has severe physical or water damage so we can assess the situation.
Where is the BCM located on my vehicle?
On most compatible GM trucks and SUVs like the Sierra, Silverado, and Tahoe, the BCM is located under the steering column, on the driver’s side of the dashboard. On other models like the Corvette or CTS, it may be in the LH dash or on the firewall.
