Tired of Your Vehicle’s Bizarre Electrical Behavior?
Is your Silverado, Corvette, or Escalade acting possessed? One minute the radio works, the next it doesn’t. The windows refuse to go down, the security light is flashing for no reason, or worse, the vehicle won’t start at all. As a technician with over two decades of experience under the hood, I’ve seen these exact issues hundreds of times. The culprit is almost always a failing Body Control Module (BCM), the central nervous system for your vehicle’s electronics. A faulty BCM can turn a reliable vehicle into a source of constant frustration. This programmed GM BCM is the definitive, hassle-free solution.
A Technician’s Notebook: The 2015 Sierra That Wouldn’t Cooperate
I remember a 2015 Sierra 1500 rolling into my bay with a laundry list of complaints from the owner. The dash lights would flicker randomly, the horn would sound when turning, and sometimes it just refused to crank. The owner had already replaced the battery and checked the alternator. After connecting my scan tool, I found a slew of communication error codes (U-codes) pointing to a network breakdown. The common link? The BCM. Instead of a costly trip to the dealer for a new module and several hours of programming fees, we used a cloned BCM. The customer simply mailed in his original module, we transferred the data to this replacement unit, and shipped it back. He installed it in under 30 minutes, and every single electrical gremlin was gone. That’s the power of a pre-programmed solution.
Common Signs of a Failing BCM
If your vehicle is experiencing any of these issues, a failing BCM is the likely cause. This programmed GM BCM service is designed to resolve them permanently.
- ✔ Intermittent or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security system light stays on or flashes, potentially causing a no-start condition.
- ✔ Inaccurate or dead gauges on the instrument cluster.
- ✔ The radio or infotainment system behaves erratically or won’t turn on.
- ✔ Key fobs stop working or work unreliably.
- ✔ Diagnostic Trouble Codes (DTCs) related to communication errors, such as U0140, U0155, or other U-codes.
How Our Simple Cloning Service Works
Forget about expensive dealership visits, towing fees, and programming charges. Our service is designed to be straightforward and get you back on the road fast. After you purchase, we will contact you with instructions to ship your original BCM to our facility. Once we receive it, our expert technicians will clone all the critical vehicle-specific data—including VIN, mileage, and key information—onto this replacement module. We then ship the fully programmed BCM back to you, typically within 24-48 hours. The result is a true plug-and-play part that is ready for installation right out of the box.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: The location varies by model. Common spots include under the steering column, behind the LH dash panel, on the firewall, or in the RH rear quarter panel (check your specific model in the fitment list below).
- ✔ Remove the Original BCM: Carefully disconnect all electrical connectors. They have locking tabs that need to be pressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New BCM: Mount the replacement module in the same position and reconnect all the electrical harnesses. Ensure they click securely into place.
- ✔ Reconnect the Battery: Reattach the negative battery terminal.
- ✔ Test All Functions: Start the vehicle and test your lights, windows, locks, radio, and other body functions to confirm the repair is successful.
Important Post-Installation Information
While our programmed GM BCM is designed for a seamless installation, some vehicle systems may require a quick sync-up. This is normal and easily addressed.
- Airbag System Sync: In some cases, the airbag (SRS) warning light may illuminate after installation. This simply means the new BCM needs to be introduced to the airbag system. A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
- Brake Pedal Position Relearn: Certain models may require a brake pedal position sensor relearn to ensure perfect communication with the traction control and ABS systems.
- No Core Charge: You are not required to return your original module to us after the service. There is no core charge or deposit.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any procedure.

Frequently Asked Questions
How does the cloning process work after I order?
After you place your order, we will email you detailed instructions and a shipping address. You’ll send us your original BCM. We then extract its unique data and transfer it to the replacement module, making it a perfect match for your vehicle. We ship the programmed unit back to you, ready for installation.
Is this really plug-and-play? Will I need to go to the dealer?
Yes, this is a true plug-and-play solution. Because we clone the data from your original module, the replacement BCM will not require any additional programming from a dealer or locksmith. This saves you significant time and money.
What is the turnaround time?
We pride ourselves on a fast turnaround. Once we receive your original BCM, we typically program and ship the replacement unit back to you within one to two business days. You will receive tracking information as soon as it ships.
Do I need to send my keys with the BCM?
No, you do not need to send us your keys. All the necessary security information is stored within the BCM itself, and our cloning process transfers it directly to the new module.
What if my airbag light comes on after I install it?
This is a possibility and is not a sign of a defective part. It means the BCM and the Supplemental Restraint System (SRS) module need to be re-synced. This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be done by any competent repair shop with a professional-grade scan tool.
