2010 Tahoe Body Control Module 20815898 | Cloning Service

Restore Your Tahoe’s Electrical System with a Reliable BCM

If you’re dealing with bizarre electrical issues in your 2010 Chevrolet Tahoe—like flickering lights, malfunctioning power windows, or a dashboard that’s lit up like a Christmas tree—the Body Control Module (BCM) is often the culprit. Think of the BCM as the central nervous system for your truck’s body electronics. When it fails, it can cause a cascade of frustrating and seemingly unrelated problems. In my two decades as a technician, I’ve seen countless vehicles where a faulty BCM was the root cause of issues that had owners and even other shops chasing their tails for weeks.

This isn’t just a replacement part; it’s a complete solution. We provide a high-quality BCM that comes with a critical Cloning Service. This means we take the essential data from your original module and transfer it to the replacement unit. By providing us with your vehicle’s VIN after purchase, we ensure the module is flashed with the latest GM software and configured specifically for your Tahoe’s options. This process eliminates the need for an expensive trip to the dealership for programming, saving you significant time and money.

Is Your Tahoe Exhibiting These Symptoms?

• ✔ Erratic or non-functional interior and exterior lights.
• ✔ Power windows, door locks, or mirrors working intermittently or not at all.
• ✔ The security system acting up, or the vehicle failing to start.
• ✔ The radio or infotainment system turning on and off by itself.
• ✔ Multiple warning lights on the dash with no clear cause.
• ✔ Diagnostic Trouble Codes (DTCs) such as U0140, B1000, or other communication-related faults.

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 BCM: On a 2010 Tahoe, the Body Control Module is typically found 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 the new, pre-programmed BCM in the same location. Securely plug in all the electrical connectors, ensuring they click into place.
5. ✔ Perform Post-Install Checks: Reconnect the battery terminal. Start the vehicle and test all functions controlled by the BCM—lights, locks, windows, radio, etc.
6. ✔ Address Any Warnings: As noted in our procedures, if the airbag light is on, a relearn procedure is needed. A brake pedal position relearn may also be required. These steps ensure all related systems communicate correctly with the new module.
