Is Your GM Truck or SUV Plagued by Bizarre Electrical Problems?
The Body Control Module (BCM) is the central nervous system for your vehicle’s electronic accessories. It manages everything from your power windows and door locks to the interior lighting, security system, and even instrument cluster functions. When the BCM starts to fail, it can create a cascade of confusing and frustrating symptoms that seem unrelated, making diagnosis a nightmare for even seasoned technicians. If your 2015 Sierra, Silverado, Tahoe, or other compatible GM vehicle is acting possessed, a faulty BCM is a likely culprit.
From the Diagnostic Bay
We had a 2015 Sierra 1500 in the shop that was driving the owner crazy. The radio would randomly change stations, the dome light would flicker while driving, and occasionally the power locks wouldn’t respond to the key fob. He’d already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication error codes pointing to the BCM. Instead of a costly trip to the dealer for a new module and several hours of programming, we performed a cloning service. By transferring the original data to a replacement unit, we had the truck’s electronics functioning perfectly in no time. It’s a straightforward solution to a very complex-seeming problem.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, locks, or mirrors.
- ✔ Erratic instrument cluster behavior (gauges dropping out, warning lights flashing).
- ✔ Interior or exterior lights not working correctly (staying on or not turning on).
- ✔ Key fob not being recognized or working sporadically.
- ✔ Vehicle security system engaging randomly or preventing the engine from starting.
- ✔ HVAC (heating and air conditioning) controls not responding.
- ✔ Communication error codes (U-codes) stored in the vehicle’s computer system.
The Simple, No-Hassle Solution: Mail-In Cloning Service
Don’t spend a fortune at the dealership on a new module and expensive programming fees. Our professional mail-in cloning service is the most efficient and cost-effective way to solve your BCM issues. We take the vital, vehicle-specific information—including VIN, mileage, and key programming—from your original BCM and flash it directly onto a replacement unit. The result is a true plug-and-play module that is ready for installation the moment you receive it.

Post-Installation Information
While our goal is a 100% plug-and-play experience, some GM vehicles have sensitive, interconnected systems that may require a simple sync procedure after installation.
- Airbag System Sync: If the airbag warning light is illuminated after you install the BCM, it means the BCM and the SDM (Sensing and Diagnostic Module) need to be re-synced. A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a quick process for any qualified repair shop.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be needed to ensure flawless operation of your brake lights and traction control system.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does this BCM cloning service include?
This service includes a quality-tested replacement BCM that has been programmed with your vehicle’s original data. We transfer the VIN, key information, and other vehicle-specific settings to make it a plug-and-play part, eliminating the need for dealer programming.
Why do I need to send my original BCM to you?
Your original BCM contains the unique data that is essential for your truck’s electronic systems to function correctly. By cloning this data, we ensure the replacement module is a perfect match for your vehicle, preserving all original features and security information.
Is this a true plug-and-play solution?
Yes, in over 95% of cases, this is a direct plug-and-play installation. In rare instances, as noted above, a simple relearn procedure for the airbag or brake pedal sensor may be required, which can be performed by any competent repair shop.
What happens if I have an airbag light after installation?
An airbag light indicates the new BCM needs to be synced with the vehicle’s Sensing and Diagnostic Module (SDM). A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
How long does the programming service take?
Once we receive your original module, our programming and testing process is typically completed within 1-2 business days. We then ship the replacement module back to you promptly.
