Restore Your Truck’s Electrical Sanity
Are you chasing electrical gremlins in your 2010 Chevrolet Avalanche? Flickering lights, malfunctioning power windows, a security system that has a mind of its own, or a dashboard lit up with warning messages? As a technician with over two decades of diagnostic experience, I’ve seen these exact frustrations countless times. The culprit is often a failing Body Control Module (BCM)—the central command center for your truck’s body electronics. A faulty BCM can turn a reliable vehicle into a source of daily headaches. This isn’t just an inconvenience; it can affect vehicle safety and security.
This replacement Body Control Module offers a direct, reliable solution. But we go a step further than the dealership. Instead of just shipping you a blank module that requires expensive programming, we provide a professional Cloning Service. You send us your original BCM, and we transfer its exact data—including key information and vehicle-specific settings—to this replacement unit. This makes installation a breeze and saves you from a costly trip to the dealer for programming. We use your VIN to ensure we are starting with the correct base software from GM, then the cloning process makes it a true plug-and-play part for your specific truck.
A Technician’s Notebook: The Avalanche That Wouldn’t Cooperate
A customer brought in his 2010 Avalanche 1500 with a bizarre list of complaints. The radio would turn off randomly, the driver’s side power lock was dead, and the anti-theft light would flash intermittently, sometimes causing a no-start condition. He’d already replaced the battery and checked all the fuses. A scan showed a handful of U-codes (communication errors) pointing to the BCM. Instead of a costly new module and programming from the dealer, we used our cloning service. We transferred the data from his failing BCM to a replacement unit. After a 20-minute install, every single issue was gone. It’s a classic case where a single component failure creates a cascade of confusing symptoms, and our cloning process provides the most efficient and cost-effective fix.
Is Your Truck Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is the likely solution:
- âś” Erratic or non-functional interior and exterior lights (headlights, dome lights).
- âś” Power windows, door locks, or mirrors working intermittently or not at all.
- âś” The security system engaging randomly, preventing the engine from starting.
- âś” Dashboard warning lights (like ABS, Airbag, or Security) staying on.
- âś” Communication-related Diagnostic Trouble Codes (DTCs), especially U-codes (e.g., U0140, U0155).
- âś” Wipers or horn activating on their own or not working when commanded.
A Straightforward Guide to Installation
Our cloning service makes this a job most DIYers can handle. The goal is to swap the modules and get you back on the road without needing a scan tool for programming.
- Purchase & Ship: After placing your order, we’ll provide instructions for shipping your original BCM to us. Please provide your VIN so we can verify the module’s compatibility.
- Cloning Process: Once we receive your module, our experts will professionally transfer all necessary data to the replacement unit and ship both modules back to you.
- Safety First: Before you begin, disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate and Remove: On the 2010 Avalanche, the BCM is typically located under the steering column, to the left of the brake pedal. Disconnect the electrical connectors and unbolt the module from its bracket.
- Install the New Module: Mount the cloned BCM in the same location, reconnect all electrical connectors securely, and re-connect the negative battery terminal.
- Post-Installation Checks: Start the vehicle and verify that all electronic functions are restored. In some cases, as detailed below, a simple relearn procedure may be required.
Important Post-Installation Notes
While our cloning service handles the primary programming, some vehicle safety systems may require a quick sync-up after the new BCM is installed.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool and syncs the BCM with the airbag module. This is only necessary if the light appears.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure correct brake light and traction control operation. This is also performed with a scan tool.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
How does the cloning service work?
After you order, you’ll ship your original BCM to us. We use specialized equipment to read the vehicle-specific data from your module and write it onto the replacement unit. We then ship both your original and the newly cloned module back to you, ready for installation.
Do I need to provide my VIN?
Yes, please provide your VIN during checkout. We use it to verify the correct hardware and base software for your vehicle before performing the cloning service, ensuring 100% compatibility.
What is your core policy? Do you keep my old BCM?
We do not require a core deposit and we do not keep your original module. Your original BCM will always be returned to you along with the cloned replacement unit.
What if I need to perform one of the post-install procedures?
The Airbag Sync and Brake Pedal Relearn procedures are typically only needed if a related warning light appears after installation. Most independent repair shops with a modern bi-directional scan tool can perform these quick procedures for you.
Is this a guaranteed fix for my vehicle’s problems?
This module will fix any issues directly caused by a faulty BCM. The symptoms listed are the most common indicators. However, proper vehicle diagnosis is key, as wiring or sensor issues can sometimes mimic a BCM failure.
