Restore Full Functionality to Your GM Truck or SUV
Are you dealing with bizarre electrical problems in your 2010 Chevrolet Avalanche? Maybe the power windows have a mind of their own, the radio cuts out unexpectedly, or you’re seeing a frustrating array of warning lights on your dash. These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can cause widespread chaos. In my 20+ years of experience, I’ve seen how a failing BCM can mimic a dozen other problems, leading to wasted time and money on incorrect diagnoses.
This isn’t just a replacement part; it’s a complete, hassle-free solution. We offer a professional cloning service for your 2010 Avalanche 1500 BCM. This means we transfer the exact data from your original module to this fully tested replacement unit. The result? You receive a module that is 100% plug-and-play. You can skip the expensive trip to the dealership, avoid their programming fees, and get your truck back to perfect working order with a simple installation you can do right in your own driveway.
A Technician’s Notebook
I remember a 2010 Tahoe—which uses this exact same BCM—that came into the shop with a complaint of intermittent ‘Service StabiliTrak’ and ‘Service Traction Control’ lights. The owner had already replaced a wheel speed sensor with no luck. A quick scan showed communication loss codes (U-codes) with the BCM. Instead of just throwing a new part at it, we checked the power and ground feeds to the module, which were solid. The issue was internal to the BCM; its communication chip was failing intermittently, especially on hot days. By providing a cloned BCM, the customer was able to install it himself and instantly solve a problem that had been plaguing him for months. It’s a perfect example of how a central component failure can send you chasing ghosts.
Is Your Avalanche Showing These BCM Failure Signs?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, your BCM is the likely culprit:
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system preventing the vehicle from starting (blinking security light).
- ✔ Horn honking randomly or not working when pressed.
- ✔ Dashboard gauges behaving erratically or going dead.
- ✔ Communication error codes, such as U0140 (Lost Communication With Body Control Module).
- ✔ ‘Service Theft Deterrent System’ or other warnings on the driver information center.
Your Straightforward BCM Installation Guide
Installing your cloned 2010 Avalanche 1500 BCM is a direct swap. Here’s a general guide to get you through it:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait about 10 minutes to ensure all systems are powered down.
- Locate the BCM: On the 2010 Avalanche, the BCM is typically located under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
- Disconnect the Connectors: Carefully release the locking tabs on the electrical connectors and unplug them from the old BCM. They are color-coded and keyed, so you can’t mix them up.
- Remove the Old Module: Unbolt or unclip the old BCM from its mounting bracket.
- Install the New Module: Mount your new, cloned BCM in the same location. Reconnect all electrical connectors, ensuring they click securely into place.
- Reconnect and Test: Reattach the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test your electronics—lights, locks, windows, etc. Once confirmed, start the vehicle.
Post-Installation Note: In some cases, additional relearn procedures may be necessary. For instance, if the airbag light is on, a ‘Setup SDM Primary Key’ procedure may be needed with a high-end scan tool. Similarly, a ‘Brake Pedal Position Relearn’ might be required for proper brake light and traction control operation. Please refer to the specific requirements for your vehicle.

Frequently Asked Questions
How does the cloning service work?
After you place your order, you’ll ship your original BCM to us. We use specialized equipment to extract the unique vehicle data (including VIN, mileage, and key information) and flash it onto the replacement module. This makes the new unit an exact electronic match for your truck, ensuring a simple plug-and-play installation.
Do I need to send you my VIN?
No, providing your VIN is not necessary for this cloning service. All the required information is contained within your original BCM, which we will extract directly. Just send us your original part.
Will I get my old BCM back?
Yes, absolutely. We always return your original module along with the newly programmed replacement unit. We do not keep customer cores.
What tools are needed for installation?
For most installations, you’ll only need basic hand tools, such as a socket set and a trim removal tool to access the BCM under the dash. No special electronic or programming tools are required for the installation itself.
What if my airbag light comes on after installation?
This is uncommon, but if it happens, it means the BCM and the airbag system (SDM) need to be re-synced. This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a professional shop with a high-level diagnostic tool. This simple procedure resolves the issue.
Is this part new or used?
This is a high-quality, fully tested, and guaranteed recycled OEM part. Each module undergoes a rigorous inspection and testing process to ensure it meets or exceeds original factory performance specifications before being programmed for your vehicle.
