Restore Command of Your Truck’s Electronics
Are you dealing with baffling electrical problems in your 2010 Chevrolet Avalanche 1500? Flickering lights, malfunctioning power windows, a security system that acts up, or worse, a truck that won’t start? These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s accessories and security. When it falters, it can create a cascade of unpredictable and frustrating issues. This replacement BCM is the definitive solution, arriving pre-programmed to your truck’s VIN for a seamless restoration of function and peace of mind.
Case Study: The Ghost in the Machine
I remember a 2010 Tahoe—which shares the same platform as the Avalanche—that came into my shop with a list of gremlins that had the owner at his wit’s end. The dome lights would stay on, the radio would randomly shut off, and the remote keyless entry worked only intermittently. The owner had already replaced the battery and checked all the fuses. After connecting my scan tool, I found a slew of communication error codes (U-codes) pointing to a network problem. Instead of chasing each individual symptom, my experience pointed directly to the BCM. We installed a VIN-programmed BCM, and like flipping a switch, every single issue was resolved. It’s a prime example of how a single component, the 2010 Avalanche 1500 BCM, can be the root of so many seemingly unrelated problems.
Is Your GM Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional interior/exterior lights.
- ✔ Power windows, locks, or mirrors operating intermittently or not at all.
- ✔ Horn honking unexpectedly or not working.
- ✔ Vehicle security system issues, including false alarms or failure to arm/disarm.
- ✔ Dashboard warning lights illuminating for no reason.
- ✔ Communication DTCs such as U0100, U0140, or other U-series codes.
- ✔ A no-start condition where the engine cranks but won’t fire up.
Your Step-by-Step BCM Installation Guide
Installing your new BCM is a manageable task for a confident DIYer. For the 2010 Avalanche, the BCM is typically located under the steering column. Always confirm the location in a service manual for your specific vehicle.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow capacitors to discharge.
- Locate the BCM: Remove the lower dash panel beneath the steering wheel to gain access to the module.
- Disconnect Connectors: Carefully unplug all electrical connectors from the old BCM. They have locking tabs, so be gentle to avoid damage.
- Remove the Old Module: Unbolt or unclip the original BCM from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in place and securely plug in all the electrical connectors.
- Reconnect Power: Re-attach the negative battery terminal.
- Perform Post-Install Checks: Start the vehicle and test all body functions—lights, locks, windows, etc. Note that some vehicles may require the post-installation procedures mentioned below.
Important Post-Installation Information
While our programming handles the vast majority of the setup, some vehicle systems may require a ‘handshake’ with the new BCM. This is normal. You may need a professional scan tool to perform the following:
- Airbag System Sync: If the airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure proper brake light and stability control operation.
We make it easy with no core charge. You can keep your old module without any extra fees or the hassle of sending it back.

Frequently Asked Questions
Why does this BCM need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the module with the exact software and settings your truck’s specific options require. This ensures all features work correctly right out of the box, saving you a trip to the dealer.
Is this a difficult part to replace myself?
For someone with basic mechanical skills and tools, this is a very manageable job. The main challenge is accessing the module, which is usually under the driver’s side dash. Our pre-programming eliminates the most difficult part of the process.
Will I lose my mileage information?
No, the odometer reading is stored in the instrument panel cluster, not the Body Control Module. Replacing the BCM will not affect your vehicle’s mileage.
What if an airbag light comes on after I install it?
This is an infrequent but possible occurrence. It simply means the new BCM needs to be electronically introduced to the airbag’s computer (SDM). A repair shop with a bi-directional scan tool can perform the ‘Setup SDM Primary Key’ procedure in a few minutes to resolve this.
What is a ‘core charge’ and why don’t you have one?
A core charge is a deposit you pay until you return your old, faulty part. We’ve eliminated this to make your purchase simpler and more affordable. You are not required to send your old part back to us.
