Restore Your Vehicle’s Core Functions and End Electrical Frustration
Are you battling bizarre electrical issues in your GM truck or car? Flickering dashboard lights, power windows with a mind of their own, or a security system that prevents your vehicle from starting? These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, a faulty BCM can cause widespread chaos. This isn’t a part you can just swap out. Dealerships often charge a fortune for a new module plus hours of labor for programming. We offer a smarter, more affordable solution.
Our professional cloning service takes the headache out of the repair. Simply send us your original BCM, and we will transfer all its vital data—including VIN, mileage, and key information—to this fully tested replacement unit. The result is a truly plug-and-play Programmed GM BCM that is ready for installation right out of the box. No expensive trips to the dealer, no complex scan tool procedures. You get your vehicle back to perfect working order with minimal downtime.
Case Study: A Tricky Diagnosis
A 2015 Silverado 3500 came into the shop with a complaint that was driving the owner crazy. The radio would randomly shut off, the dome light wouldn’t work, and occasionally, the truck wouldn’t start, displaying a ‘Service Theft Deterrent System’ message. Scans showed a handful of intermittent communication codes (U-codes). Instead of just replacing parts, we checked the BCM connectors for corrosion—a common issue. They were clean. After monitoring live data, we saw the BCM was intermittently dropping offline. By providing a cloned BCM, the customer avoided a $1200+ dealership bill and had his work truck back on the road the next day. This is why a reliable Programmed GM BCM is the go-to fix.
Is Your GM Vehicle Showing These Symptoms?
A failing BCM can manifest in many ways. If you’re experiencing any of the following, your Body Control Module is the likely culprit:
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, locks, or mirrors working intermittently or not at all.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ ‘Service Theft Deterrent System’ or other security-related warnings.
- ✔ A vehicle that cranks but refuses to start.
- ✔ False warnings on the instrument cluster (e.g., door ajar).
- ✔ Communication error codes, particularly U-codes like U0140, indicating a loss of communication with the BCM.
A Straightforward Guide to BCM Replacement
Our cloning service makes the physical installation simple. While the BCM location varies slightly by model (often under the steering column or behind the driver’s side dash/firewall), the general process is straightforward for a DIYer with basic tools.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On most Silverado and Sierra models, it’s under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old BCM from its mounting bracket.
- Install the New Module: Seat your new, pre-programmed BCM into the mounting bracket and securely plug in all the electrical connectors. You should hear a click as they lock into place.
- Reconnect and Test: Re-install any trim panels you removed, then reconnect the negative battery terminal. Start the vehicle and test all body functions—lights, locks, windows, radio, etc.—to confirm the repair was successful.
Important Post-Installation Notes
While our goal is a 100% plug-and-play experience, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following possibilities:
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be required to ensure your brake lights and stability control systems function correctly.
- No Core Charge: You’ve already sent us your module for the service, so there’s no core to return. You can keep your original non-working module.
Disclaimer: Vehicle systems vary. For procedures specific to your exact model, always consult a factory service manual or a qualified automotive technician.

Frequently Asked Questions
How does the mail-in programming service work?
After you purchase, we will provide you with shipping instructions. You send us your original BCM. We then transfer its unique data to the replacement module and ship it back to you, typically within one business day of receiving yours.
Will I need to have a dealer program this module?
No. Our cloning service makes this a plug-and-play part. All necessary vehicle-specific programming, including the VIN and security information, is transferred from your old unit. This saves you hundreds in dealership fees.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM isn’t functioning in the vehicle, we can still extract the necessary data from the memory chip. Please contact us with details about your module’s condition if you have concerns.
Is this a guaranteed fix for my vehicle’s problems?
This module will fix problems directly caused by a faulty BCM. It’s crucial to properly diagnose the issue, as similar symptoms can sometimes be caused by bad wiring, grounds, or other modules. Our description lists the most common BCM failure symptoms.
What tools do I need for installation?
Typically, you’ll only need basic hand tools like a socket set and a trim removal tool to access and remove the lower dash panels. No special electronic tools are required for the installation itself.
