Restore Full Control of Your Truck’s Electronics
Is your 2010 Chevrolet Avalanche 1500 suffering from bizarre electrical problems? Flickering lights, unresponsive power windows, or a security system that has a mind of its own are classic signs of a failing Body Control Module (BCM). As the central hub for your truck’s body electronics, a faulty BCM can cause widespread and frustrating issues. This is a direct-fit, VIN-programmed replacement BCM, part number 25892622, designed to solve those problems and get your truck’s features working reliably again.
Case Study: A Tricky Diagnosis
I remember a 2010 Avalanche that came into my shop with a complaint that was all over the map. The radio would turn off randomly, the driver’s side power window wouldn’t work, and the “Service 4WD” light was on, even though the transfer case was fine. The owner had already replaced the window switch and a battery. After scanning the network, I found multiple U-codes (communication errors), specifically a U0140 – Lost Communication with Body Control Module. This pointed directly to a failing BCM. Instead of a complex rewiring job, we installed a VIN-programmed module like this one. It immediately cleared all the communication faults and restored every function. It’s a textbook example of how a single failing module can create chaos across multiple systems.
Is Your Avalanche Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Interior dome lights or dashboard lights flickering or staying on.
- ✔ The security system light is illuminated, or the vehicle won’t start due to a security fault.
- ✔ Horn, wipers, or other accessories activating on their own.
- ✔ Diagnostic Trouble Codes (DTCs) related to communication errors, such as U0140, U0155, or B1001.
- ✔ Inconsistent operation of the heating and A/C blower motor.
The Simple Solution: VIN Programming Included
The biggest headache with replacing a BCM has always been the expensive and time-consuming programming required at a dealership. We eliminate that step entirely. Our Cloning Service makes this a true plug-and-play repair. Simply provide us with your vehicle’s 17-digit VIN during checkout, and our technicians will program this module with your truck’s specific configuration and the latest GM software updates. When the part arrives, it’s ready for installation, saving you hundreds of dollars and a trip to the dealer.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your truck’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: On the 2010 Avalanche, the Body Control Module is typically located under the driver’s side of the dashboard, near the steering column.
- ✔ Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once unplugged, unbolt the module from its mounting bracket.
- ✔ Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely plug in all the electrical connectors. You should hear a ‘click’ as they lock into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘ON’ position and test all functions: power windows, locks, lights, wipers, and radio.
Important Post-Installation Steps
In some cases, additional synchronization procedures may be needed after installation. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is on after you’ve installed the BCM, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure correct brake light and traction control operation, a brake pedal position sensor relearn might be required. This can also be performed with a capable diagnostic tool.
Please note: Your original module will be returned to you along with the replacement unit. We do not require your core.

Frequently Asked Questions
What exactly is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that acts as the central command center for all body-related electronics. This includes power windows, locks, interior and exterior lighting, wipers, the security system, and more. When it fails, these systems can become erratic or stop working altogether.
How does the VIN programming (Cloning Service) work?
After you place your order, you provide us with your vehicle’s 17-digit VIN. Our technicians use this number to access the specific software and vehicle options from GM’s database. We then flash this information onto the replacement BCM, making it a perfect electronic match for your truck.
Do I need to send my original BCM to you?
No. This service does not require you to send us your part. We program a replacement module and ship it to you. We also return your original module with the shipment, as we do not keep cores.
Will this BCM fix my specific electrical problem?
If you’re experiencing several of the symptoms listed above (like issues with locks, windows, and lights simultaneously) and/or have communication-related DTCs, a failing BCM is the most likely cause. This part is designed to fix those exact issues.
What tools are needed for installation?
Basic hand tools are all that’s required for the physical installation, typically a socket set to remove the module and potentially a trim removal tool for dash panels. No special electronic tools are needed, as the programming is done beforehand.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance if you are unsure about any step of the process.
