Are you chasing electrical gremlins in your 2010 Chevrolet Tahoe? Flickering lights, malfunctioning power windows, strange dash warnings, or a security system that prevents your truck from starting are all classic signs of a failing Body Control Module (BCM).

You get a part that is truly plug-and-play, saving you hundreds of dollars and getting you back on the road fast.

A Technician’s Notebook: The Tahoe with a Mind of Its Own

I remember a 2010 Tahoe that rolled into my bay last winter. The customer was at his wit’s end. The dome lights would randomly turn on while driving, the radio would shut off, and the ‘Service Stabilitrak’ warning was a permanent fixture on the dash. He’d already replaced the battery and checked grounds, but the problems persisted. A quick scan showed a flurry of U-codes, all pointing to communication loss with the BCM. We confirmed the diagnosis and explained our cloning service. He was skeptical about avoiding the dealer, but trusted the process. After we sent him the cloned 2010 Tahoe Body Control Module, he installed it in his driveway in under 30 minutes. The next day, he called back, ecstatic. All the phantom electrical issues were gone. That’s the power of a properly programmed module—it’s not just a part, it’s a complete fix.

Is Your Vehicle Showing These Symptoms?

  • ✔ Erratic or non-functional interior/exterior lights.
  • ✔ Power windows, locks, or mirrors working intermittently or not at all.
  • ✔ The security or anti-theft system light is on, possibly causing a no-start condition.
  • ✔ False warnings on the instrument cluster (e.g., ‘Service Airbag,’ ‘Service Stabilitrak’).
  • ✔ Communication-related Diagnostic Trouble Codes (DTCs) such as U0140, U0155, or B1001.
  • ✔ Unresponsive key fob or remote start functions.

Your Straightforward BCM Installation Guide

  1. ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait about 10 minutes to allow the systems to fully discharge.
  2. ✔ Locate the BCM: On a 2010 Tahoe, the Body Control Module is typically located under the driver’s side of the dashboard, to the left of the steering column. You may need to remove a lower dash panel for access.
  3. ✔ Disconnect the Old Module: Carefully unplug the electrical connectors from the original BCM. These connectors have locking tabs that need to be depressed before pulling. Never force them.
  4. ✔ Swap the Modules: Remove the old BCM from its mounting bracket and install your new, pre-programmed module in its place.
  5. ✔ Reconnect and Power Up: Plug the electrical connectors securely into the new BCM. You should hear a ‘click’ as they lock into place. Reconnect the negative battery terminal.
  6. ✔ Final System Checks: Start the vehicle and test all body functions—lights, windows, locks, wipers, etc. Note the important post-installation procedures below.

Important Information After Installation

Our cloning service handles the vast majority of the setup, but some vehicle systems may require a relearn procedure after the BCM is replaced. This is normal and ensures all components communicate correctly.

  • 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 professional 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 clear any traction control faults.

Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified mechanic if you are unsure about any step.

Frequently Asked Questions

How does the cloning service work?

After you place your order, you will ship your original BCM to us. We use specialized equipment to extract the key vehicle data (like VIN, mileage, and security information) and flash it onto the replacement module. This makes the new module a perfect electronic match for your vehicle, eliminating the need for dealer programming.

Will I need a scan tool or a trip to the dealer after installation?

No! The primary benefit of our cloning service is that it completely removes the need for expensive dealership programming. The module arrives ready for installation. The only exception is the potential need for a relearn procedure, like for the airbag system, if a warning light appears.

What happens to my original BCM?

We believe in transparency and returning your property. Your original module is always returned to you along with the newly programmed replacement unit. We do not keep your old part.

Where is the BCM located on my 2010 Tahoe?

In the 2010 Chevrolet Tahoe, the Body Control Module is located inside the cabin, underneath the dashboard to the left of the steering column. Access typically requires removing the lower dash cover.

My part number is slightly different. Will this still work?

Yes, most likely. This BCM is a direct replacement for a long list of GM part numbers. Please check our detailed part number list above to confirm that your module’s number is included. If it is, this part is a guaranteed compatible replacement.
