Restore Your Truck’s Functionality and Peace of Mind
Are you dealing with baffling electrical problems in your GM truck or car? One moment the power windows work, the next they don’t. Maybe your dash lights are flickering, the radio is acting possessed, or worse, you’re experiencing intermittent no-start conditions. These aren’t just annoyances; they’re classic symptoms of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can wreak havoc. This isn’t a part you can just swap out. Dealerships will charge a fortune for a new module and the mandatory programming. We offer a smarter, more affordable solution.
This is a comprehensive cloning service for your vehicle’s BCM. You simply send us your original module, and we transfer all of its critical data—including VIN, mileage, and key programming—to this fully tested replacement unit. The result? You receive a module that is 100% plug-and-play. No trips to the dealer, no expensive scan tool programming required. It’s the most direct path to getting your vehicle back to normal.
A Technician’s Notebook: The BCM That Mimicked a Bad Battery
I once had a 2015 Silverado 2500 in the bay with a complaint of random no-starts and a battery that kept dying. The owner had already replaced the battery twice and the alternator once. Diagnostics showed the battery was indeed being drained, but all the usual suspects checked out. After digging into the data stream, I noticed the BCM wasn’t letting other modules go to ‘sleep’ after shutdown. It was causing a parasitic draw that killed the battery overnight. A cloned 2015 Silverado 2500 BCM solved the problem instantly, saving the customer from throwing more parts at it. It’s a perfect example of how a BCM is the hidden cause of many frustrating issues.
Common Signs of a Failing BCM
If your vehicle is experiencing any of the following, a faulty BCM is the likely culprit. A failing module can often set communication codes like U0140, U0155, or other B-series body codes.
- ✔ Erratic or non-functional power windows, door locks, and interior lights.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Inconsistent operation of windshield wipers.
- ✔ False security system alarms or anti-theft light staying on.
- ✔ Dashboard warning lights illuminating for no reason.
- ✔ Intermittent no-start or crank-no-start conditions.
- ✔ Communication issues with diagnostic scan tools.
A Straightforward Guide to Our Cloning Service and Installation
- ✔ Place Your Order: After you complete your purchase, we will contact you with detailed instructions and a shipping address. Please ensure your contact information is up to date.
- ✔ Ship Your Original BCM: Carefully package and send your vehicle’s original BCM to us. You are responsible for this initial shipping cost.
- ✔ We Handle the Programming: Upon receipt, our expert technicians will perform a full data transfer from your original module to this replacement unit. This process perfectly clones all necessary vehicle-specific information.
- ✔ Receive Your Plug-and-Play Module: We ship the newly programmed module back to you, typically within 1-2 business days. Tracking information will be provided.
- ✔ Installation: Disconnect the negative battery terminal. Locate and remove your old BCM (often found under the steering column or on the driver’s side firewall). Install the programmed replacement module, reconnect the connectors, and then reconnect the battery. Start your vehicle and test all functions.
Important Post-Installation Notes
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. This is normal and easily addressed.
- Airbag System Sync: If the airbag warning light is on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade diagnostic tool to sync the systems and clear the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light operation and to keep the traction control system happy.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a qualified technician if you are unsure about any procedure.

Frequently Asked Questions
Why do I need to send my original BCM?
Your original BCM contains the unique identity of your vehicle, including the VIN, security information for your keys, and specific option configurations. By cloning this data, we make the replacement module a true plug-and-play part, saving you from expensive and complex dealership programming.
Is this a difficult part to install myself?
For most DIYers with basic tools, the physical swap is straightforward. The BCM is typically located under the driver’s side dash and is held in by a few bolts or clips. The main challenge is accessing it. Our cloning service eliminates the hardest part—the software programming.
Will this fix my specific problem?
This module will resolve issues directly caused by a faulty BCM, such as the symptoms listed above. It will not fix problems related to other failed components (e.g., a bad window motor or a faulty sensor). Proper diagnosis is key.
What is the turnaround time?
Once we receive your original module, we typically program and ship the replacement unit within one to two business days. Your total downtime will depend on shipping times to and from our facility.
Do I need to return this module for a core charge?
No. There is no core charge associated with this purchase. You send us your original module for the data transfer service only.
What if my airbag light comes on after installation?
This is a known possibility. It simply means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A repair shop with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
