Restore Your Truck’s Electrical System and End the Frustration
Are you dealing with bizarre electrical problems in your 2010 Chevrolet Avalanche 1500? Flickering lights, power windows and locks with a mind of their own, or a security light that prevents your truck from starting can all point to one culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to go, it can cause a cascade of confusing and annoying issues. Stop chasing electrical gremlins and get a definitive, reliable solution.
This isn’t just a replacement part; it’s a complete, hassle-free service. We provide a quality-tested BCM that is professionally prepared for your specific truck using our expert Cloning Service. You simply send us your original BCM, and we transfer all the critical vehicle-specific data—like your VIN, key information, and factory options—to the replacement unit. We then ship both your original module and the ready-to-install replacement back to you. This process makes the replacement a true plug-and-play solution, saving you from a costly trip to the dealership for programming.
Case Study: The Ghost in the Machine
I remember a 2010 Tahoe—which uses the same platform as your Avalanche—that came into my shop with a laundry list of intermittent electrical complaints. The owner was at his wit’s end. The radio would turn off randomly, the door locks would cycle while driving, and sometimes the truck just wouldn’t start. A scan tool showed a dozen communication error codes (U-codes) pointing to a network failure. After verifying the main power and ground circuits to the BCM were solid, it was clear the module itself was failing internally. We performed a cloning service just like this one, and the new module resolved every single issue. The customer was thrilled to have his truck back to normal without a massive dealership bill. This is the exact peace of mind we offer with this 2010 Avalanche 1500 BCM service.
Is Your Truck Plagued by These Electrical Gremlins?
- ✔ Power windows, mirrors, or door locks operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not working.
- ✔ The security or anti-theft light is on, causing a no-start condition.
- ✔ The horn honking unexpectedly or not working when pressed.
- ✔ False warnings on the driver information center (e.g., “Service 4WD” or “Service Tire Monitor System”).
- ✔ Multiple communication DTCs, such as U0140, U0155, or U0164, stored in other modules.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow all modules to power down completely.
- ✔ Locate the BCM: On your 2010 Avalanche 1500, the Body Control Module is typically located under the driver’s side of the dashboard, to the left of the steering column. You may need to remove a lower dash panel for access.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount the new, cloned BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- ✔ Reconnect and Test: Reinstall any panels you removed, then reconnect the negative battery terminal. Turn the key to the ‘ON’ position and test all body functions—windows, locks, lights, etc.—to confirm the repair.
Important Notes After Installation
Thanks to our cloning service, additional programming is typically not required. However, in some cases, you may need to perform a simple relearn procedure:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a professional scan tool may be needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position: Some models may require a brake pedal position sensor relearn to ensure proper brake light and stability control function.
Always consult a factory service manual or a qualified technician if you are unsure about any step. Your original module is always returned with the replacement unit; we do not keep the core.

Frequently Asked Questions
Frequently Asked Questions
What is a BCM cloning service?
Cloning is a process where we transfer the exact software, VIN, and security data from your original, failing BCM to a fully functional replacement module. This makes the new part plug-and-play, avoiding the need for expensive dealership programming.
Do I need to program this module after I install it?
No. Because we clone your original data, this 2010 Avalanche 1500 BCM will arrive ready to install with no additional programming required. This is the key benefit of our service.
Where is the BCM located on my 2010 Avalanche 1500?
The Body Control Module is located inside the cabin, under the driver’s side dashboard, generally to the left of the steering column.
What do I do if my airbag light comes on after installation?
While uncommon with our cloning service, if the airbag light appears, it means the BCM and the airbag module (SDM) need to be re-synchronized. This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Do I need to send my old BCM to you?
Yes, the cloning service requires your original module to read the vehicle-specific data. After you purchase, we will provide instructions for sending it to us. We will return your original module with your newly prepared replacement.
