2010 Tahoe Body Control Module 20864767 | Cloning Service Included

End the Electrical Gremlins in Your 2010 Tahoe

Is your Chevy Tahoe acting possessed? Flickering dash lights, power windows with a mind of their own, or a security system that randomly prevents you from starting the engine are all classic signs of a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen these exact issues countless times. The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and unpredictable problems. This isn’t just an annoyance; it’s a reliability issue that can leave you stranded.

This isn’t just a replacement part; it’s a complete solution. We offer a professional Cloning Service for this 2010 Tahoe Body Control Module. This means we transfer the essential data from your original, faulty BCM directly onto this replacement unit. This process preserves your vehicle’s specific key information, mileage, and other security settings, making the installation process as close to plug-and-play as possible. You get the benefit of the latest GM software updates—which we apply using your VIN—combined with the unique configuration of your truck, all without a costly trip to the dealership for programming.

Is Your Tahoe Showing These Signs of BCM Failure?

• ✔ Erratic or non-functional power windows, door locks, or mirrors.
• ✔ Interior or exterior lights that won’t turn on or off correctly.
• ✔ The security or anti-theft system light is on, causing a no-start condition.
• ✔ The horn sounds randomly or doesn’t work at all.
• ✔ Dashboard warning lights appearing for no reason.
• ✔ Communication error codes stored, such as U-series codes (e.g., U0140 – Lost Communication With Body Control Module).

A Straightforward Guide to Installation

1. ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
2. ✔ Locate the BCM: On a 2010 Tahoe, the Body Control Module 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 BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
5. ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all related functions: lights, locks, windows, etc.
6. ✔ Perform Relearns (If Needed): As noted below, some vehicles may require a ‘Setup SDM Primary Key’ or ‘Brake Pedal Position Relearn’ procedure if specific warning lights are present after installation. This may require a professional scan tool.

Important Post-Installation Information

Our cloning service handles the most critical programming, but due to the complexity of modern vehicle networks, some systems may need to be re-synced after the new BCM is installed.

• Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This syncs the BCM with the airbag module and requires a professional-grade diagnostic tool.
• Brake Pedal Position Relearn: On some models, the brake pedal position sensor may need to be recalibrated to ensure correct operation of the brake lights and stability control systems.

Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified mechanic for your specific model.
