Restore Full Electrical Control to Your GM Vehicle
Are you battling frustrating electrical gremlins in your 2010 Avalanche 1500? Flickering interior lights, power windows with a mind of their own, or a security system that randomly acts up are more than just annoyances—they’re signs that your vehicle’s central command center, the Body Control Module (BCM), may be failing. The BCM is the brain behind your truck’s comfort and convenience features. When it malfunctions, it can cause a cascade of confusing and unpredictable problems. This isn’t just a part; it’s the solution to getting your truck back to the reliable vehicle you depend on.
We take the guesswork and high dealership costs out of the equation. This BCM isn’t just a replacement part; it’s a complete solution. We provide a professional Cloning Service, where we transfer your vehicle’s specific data from your original module to this replacement unit. Simply provide us with your VIN after purchase, and we’ll handle the programming. The module arrives at your door, ready for installation, with the latest GM software updates already applied. This eliminates the need for expensive dealer-specific tools or post-installation programming fees.
Case Study: A Tricky Diagnosis
I remember a 2010 Tahoe that came into my shop with a bizarre set of symptoms. The owner complained of an intermittent no-start condition and the radio turning on by itself, even when the truck was off, leading to a dead battery. We checked the battery and alternator, which were fine. A scan showed a slew of communication codes, including the notorious U0140 (Lost Communication with BCM). After confirming the power and ground connections to the BCM were solid, we knew the module itself was the culprit. A faulty internal processor was causing data corruption on the CAN bus network. By installing a VIN-programmed 2010 Avalanche 1500 Body Control Module (the same part family), we resolved all the electrical ghosts in one shot, saving the customer hundreds compared to the dealership’s quote.
Is Your Vehicle Showing These Symptoms?
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security system light stays on, or the alarm goes off unexpectedly.
- ✔ A battery that drains overnight for no apparent reason (parasitic draw).
- ✔ Inaccurate or dead gauges on the instrument cluster.
- ✔ Communication error codes stored, such as U0140, U0155, or B1001.
- ✔ Remote keyless entry (RKE) system failure.
A Straightforward Guide to BCM Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- ✔ Locate the BCM: On the 2010 Avalanche 1500, the BCM is typically located under the steering column, secured to a mounting bracket. 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 the module from its bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM onto the bracket and securely reconnect all the electrical connectors. You should hear a click as they lock into place.
- ✔ Reconnect and Test: Reinstall any trim panels you removed. Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—windows, locks, lights, radio, etc.—to confirm the repair.
Important Post-Installation Notes
While our cloning service handles the primary programming, some vehicle systems may require a relearn procedure after the BCM is replaced. This is a normal part of the process.
- Airbag System Sync: If your airbag warning light is illuminated after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure your brake lights and traction control system function correctly.
Disclaimer: Always refer to a factory service manual for procedures specific to your vehicle’s exact year and model.

Frequently Asked Questions
What is a BCM cloning service?
It’s a process where we transfer the vital, vehicle-specific information (like VIN, mileage, and security keys) from your original BCM to the replacement unit. This makes the new module plug-and-play, avoiding the need for a trip to the dealer for expensive programming.
Do I need to do any programming myself?
No. Our cloning service handles all the necessary programming before we ship the part to you. It will arrive ready to be installed in your vehicle.
What do you do with my old BCM?
Our service is a data transfer service. Your original module is always returned to you along with the programmed replacement unit. We do not keep your core.
How do I provide my VIN number?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit VIN. We cannot program and ship your BCM without it.
Will this fix my airbag light?
A faulty BCM can cause the airbag light to come on. While this module will fix the root cause, the system may require a “sync” procedure with a professional scan tool to clear the light after installation, as detailed in our post-installation notes.
