Programmed 2010 Tahoe Body Control Module 15872388 | VIN Flashed

Restore Full Functionality to Your GM Vehicle

Are you chasing down bizarre electrical gremlins in your 2010 Chevy Tahoe? One minute the power locks work, the next they don’t. Maybe your interior lights are flickering, the security system is acting up, or you’re seeing strange warning messages on the dash. As a technician with over two decades of experience, I can tell you these are classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s comfort and convenience features, and when it starts to go, it can cause a cascade of frustrating, seemingly unrelated problems.

What Makes Our BCM the Smartest Fix?

Forget the hassle and expense of a dealership visit. A blank BCM from the dealer requires costly programming with their proprietary tools. We eliminate that step entirely. When you purchase this module, you simply provide us with your vehicle’s VIN. We then flash the module with the latest official GM software specific to your 2010 Tahoe Body Control Module, ensuring it works correctly right out of the box. This saves you time, hundreds of dollars in labor, and the headache of coordinating a tow or visit to a service center.

Common Signs of a Failing BCM

• ✔ Erratic or non-functional power windows, door locks, and mirrors.
• ✔ Interior or exterior lights (headlights, dome lights) that flicker, stay on, or won’t turn on at all.
• ✔ The security system engaging randomly or preventing the vehicle from starting (Security light on).
• ✔ Unexplained parasitic battery drain that kills your battery overnight.
• ✔ Warning lights on the dash, such as for the airbag or traction control system.
• ✔ Communication error codes, often in the U-series (e.g., U0140, U0155), indicating a loss of communication with the BCM.

Your Straightforward BCM Installation Guide

1. ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
2. ✔ Locate the Module: On the 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 pressed. 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. Securely plug in all the electrical connectors, ensuring they click into place.
5. ✔ Power Up and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions: lights, locks, windows, radio, etc.
6. ✔ Perform Relearns if Needed: As noted below, some vehicles may require an airbag system sync or a brake pedal position relearn. If you see an airbag light, this procedure will be necessary.

Post-Installation Procedures & Notes

While this module is programmed for your VIN, certain vehicle systems may need to be re-synchronized after installation. Please be aware of the following potential requirements:

• Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible high-level scan tool. This syncs the new BCM with the airbag system.
• Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light operation and to prevent issues with the traction control/stability systems.
• No Core Charge: You are not required to return your old module. There is no core charge or deposit associated with this purchase.

Disclaimer: Vehicle systems vary. Always refer to a factory service manual or consult with a certified technician for procedures specific to your vehicle.
