Is Your GM Vehicle Plagued by Electrical Gremlins?
The Body Control Module (BCM) is the central command center for your vehicle’s electronic accessories. It manages everything from your power windows and door locks to the interior lights, security system, and climate controls. When the BCM starts to fail, it can cause a cascade of confusing and frustrating issues that can be difficult to diagnose. If your 2015 Chevrolet Tahoe, GMC Sierra, Cadillac Escalade, or other compatible GM vehicle is experiencing bizarre electrical problems, a faulty BCM is a very likely culprit.
From the Diagnostic Bay
We had a 2015 Tahoe in the shop that was driving its owner crazy. The radio would randomly shut off, the driver’s side power window would only work intermittently, and the anti-theft light would flash for no reason, sometimes preventing the truck from starting. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication loss codes (U-codes) pointing to the BCM. A failing processor inside the original 2015 Tahoe BCM was corrupting data on the network, causing these ghost-like problems. Instead of a costly new module and programming at the dealer, we provided a cloned BCM that solved every single issue instantly.
Common Symptoms of a Failing BCM
A failing Body Control Module can manifest in numerous ways. Look out for these common warning signs:
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ The security system engaging randomly, causing a no-start condition.
- ✔ Headlights, taillights, or interior dome lights staying on or not turning on.
- ✔ The key fob failing to lock or unlock the doors.
- ✔ Dashboard warning lights (like Airbag, ABS, or StabiliTrak) illuminating without a clear cause.
- ✔ Climate control functions not responding correctly.
- ✔ Horn honking unexpectedly or not working when pressed.
The Simple, Plug-and-Play Solution
Forget expensive dealership visits and complex programming procedures. Our professional cloning service is the most efficient and cost-effective way to fix your vehicle. We transfer all the vital information from your original BCM to a fully functional replacement unit. This process copies your vehicle’s unique VIN, mileage, key fob data, and specific RPO codes (factory options), making the replacement module a perfect digital twin of your original.

Post-Installation Procedures
While our goal is a seamless installation, some vehicles may require minor recalibration procedures after the BCM is replaced. These are simple tasks that can often be performed with a high-end diagnostic tool.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure may be needed to sync the modules.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure proper brake light and traction control operation.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What data is transferred during the cloning process?
We perform a complete data transfer, which includes your vehicle’s VIN, immobilizer/key data, mileage, and all factory-programmed options (RPO codes). This ensures the replacement module works perfectly with your vehicle’s existing systems.
Is this really a plug-and-play solution?
Yes. Because we clone your original module’s data, the replacement BCM is 100% plug-and-play. In most cases, you will not need to perform any additional programming or visit a dealership after installation.
How long does the programming service take?
Our standard turnaround time is 24-48 business hours from the time we receive your original module. We then ship your original and the newly programmed replacement back to you.
What if my original BCM is completely dead or water damaged?
Even if a BCM is not functioning in the vehicle, we can often still extract the necessary data directly from the memory chips. If you believe your module is severely damaged, please contact us before ordering to discuss the recovery possibilities.
Do I need to send my keys or any other parts with the BCM?
No, you only need to ship your original Body Control Module to us. All the required security and key information is stored within the BCM itself.
