2010 Tahoe Body Control Module 15276271 | Cloning Service

Are you battling frustrating electrical issues in your 2010 Chevy Tahoe? Flickering lights, unresponsive power windows, or a security system that has a mind of its own are all classic signs of a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can cause a cascade of confusing problems. I’ve seen it hundreds of times in my shop: a customer comes in with a list of seemingly unrelated electrical gremlins, and the culprit is this single module.

Forget the hassle and expense of a dealership visit. This isn’t just a replacement part; it’s a complete, ready-to-install solution. We offer a professional Cloning Service for this BCM. Here’s how it works: after your purchase, you simply send us your original BCM. We then transfer its unique programming and vehicle-specific data—including key information and security settings—directly to this replacement unit. We also install the latest GM software updates to ensure optimal performance. The result? You receive a module that is 100% plug-and-play for your vehicle. No programming, no special tools, no headaches.

Common Signs of a Failing BCM

• ✔ Erratic or non-functional power windows, door locks, and interior lights.
• ✔ The security or anti-theft system activates randomly or prevents the vehicle from starting.
• ✔ Dashboard warning lights (like ABS, Airbag, or Traction Control) illuminate for no reason.
• ✔ A/C and climate control systems behaving unpredictably.
• ✔ Communication failure codes, often in the U-series (e.g., U0100, U0140), indicating the BCM is not communicating with other modules.
• ✔ Wipers or radio turning on and off by themselves.

A Straightforward Guide to Your BCM Installation

1. ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
2. ✔ Locate the BCM: On a 2010 Tahoe, the BCM is typically located under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
3. ✔ 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.
4. ✔ Install the New Module: Mount your new, cloned BCM in the same location and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
5. ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test all body functions: windows, locks, lights, radio, and wipers.

Important Post-Installation Notes

While our cloning service makes this a plug-and-play process, some vehicle systems may require a ‘handshake’ with the new BCM. Please note the following:

• Airbag System Sync: If the airbag warning light is on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure must be done with a compatible professional scan tool. This is only necessary if the light appears.
• Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light and traction control operation.

Disclaimer: Procedures can vary. Always refer to a factory service manual or a qualified professional if you are unsure.
