Restore Your Tahoe’s Electrical Systems with a Reliable, Programmed BCM
If you’re dealing with bizarre electrical issues in your 2010 Chevy Tahoe—like flickering lights, power windows with a mind of their own, or random warning messages on the dash—you’re likely facing a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen these symptoms countless times. The BCM is the central command center for your truck’s body electronics, and when it goes, it can cause a cascade of frustrating and unpredictable problems. This isn’t just an annoyance; it can be a safety issue when exterior lights or security systems are affected.
Forget the expensive trip to the dealership and the long wait for programming appointments. We offer a direct, reliable solution. This is a high-quality replacement Body Control Module, part number 25934763, that comes with our expert Cloning Service. Simply provide us with your vehicle’s VIN after purchase, and we’ll flash the module with the latest GM software specific to your Tahoe’s configuration. It arrives at your door ready for installation, saving you hundreds in dealership programming fees and getting you back on the road fast.
A Technician’s Notebook: The Case of the Haunted Tahoe
A customer brought in a 2010 Tahoe with a list of complaints that sounded like something out of a ghost story. The dome lights would stay on, the radio would shut off randomly, and the key fob worked only intermittently. He’d already replaced the battery, thinking it was a simple voltage issue. After connecting my scan tool, I found a slew of ‘U’ codes, indicating a loss of communication between various modules. The common link? The BCM. We swapped in a VIN-programmed module just like this one, and instantly, all the gremlins vanished. It’s a classic BCM failure scenario that I’ve diagnosed and fixed on hundreds of these GM trucks and SUVs.
Is Your Tahoe Exhibiting These Symptoms?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, your Body Control Module is the most likely culprit:
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The security system acting up, preventing the vehicle from starting.
- ✔ Horn sounding unexpectedly or not working at all.
- ✔ Dashboard warning lights like “Service StabiliTrak” or ABS lights illuminating without a clear cause.
- ✔ Diagnostic Trouble Codes (DTCs) related to communication errors, such as U0140 (Lost Communication With Body Control Module).
Your Straightforward BCM Installation Guide
Replacing the BCM on your 2010 Tahoe is a manageable job for a confident DIYer. The module is typically located under the driver’s side of the dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before starting any electrical work.
- Locate the BCM: On the 2010 Tahoe, it’s under the steering column. You may need to remove a lower dash panel for access.
- Disconnect Connectors: Carefully unplug all the electrical connectors from the old BCM. They have locking tabs, so don’t force them. A small flathead screwdriver can help depress the tabs.
- Remove the Old Module: Unbolt or unclip the old BCM from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors.
- Reconnect Battery: Reattach the negative battery terminal.
- Perform Relearns: Start the vehicle and check all functions. As noted below, some simple relearn procedures may be required to sync the new module completely.
Important Post-Installation Steps
Because this module is central to many systems, a couple of quick synchronization procedures may be necessary after installation:
- Airbag System Sync: If the airbag light is on after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure your brake lights and traction control system function correctly.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual for procedures specific to your vehicle.

Frequently Asked Questions
What is a Cloning Service?
Our cloning service means we transfer the essential vehicle-specific data from your original BCM to the replacement unit. This ensures the module works seamlessly with your truck’s existing keys, security system, and factory options without needing a trip to the dealer for programming.
Do I need to send my original BCM to you?
No, this service is based on your VIN. After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. We use this to program the replacement BCM with the correct software and calibration files from GM before shipping it to you.
Do you need my old BCM back as a core?
No core charge is required for this part. We do not need you to return your original module.
Will this fix my ‘Service StabiliTrak’ message?
In many cases, yes. The BCM is a key component in the StabiliTrak system. If the module is failing and causing communication errors, replacing it can resolve these warnings. However, the StabiliTrak system has other components, so a proper diagnosis is always recommended.
Is this a simple plug-and-play installation?
Yes, for the most part. Because we pre-program it to your VIN, it eliminates the most difficult step. You simply need to physically swap the modules. As noted, a minor relearn procedure for the airbag or brake pedal sensor may be required in some instances.
