Tired of Bizarre Electrical Problems in Your GM Vehicle?
As a technician with over two decades of experience, I’ve seen it all. A customer comes in with a 2015 Tahoe, and the symptoms are all over the place: the radio cuts out, the power windows have a mind of their own, the security light is flashing, and the dash is lit up like a Christmas tree. The root cause? Very often, it’s a failing Body Control Module (BCM). This module is the central nervous system for your vehicle’s body electronics, and when it goes, it creates chaos. Dealerships often quote a small fortune for a new module plus hours of expensive programming. Our solution puts you back in control.
This is a professional cloning service for your 2015 Tahoe BCM. You simply send us your original, faulty module. We then transfer all of its critical data—including your vehicle’s VIN and specific electronic settings—to a fully tested replacement unit. The result is a true plug-and-play module that arrives at your door ready for installation, eliminating the need for a trip to the dealer. We handle the complex programming so you can get your vehicle back to 100% functionality with a simple part swap.
From the Diagnostic Bay
I remember a 2015 Silverado 1500 that came into the shop with the owner at his wit’s end. The interior lights would flicker, the key fob worked intermittently, and he was getting a ‘Service StabiliTrak’ message. He’d been quoted over $1,200 at the dealership for a new BCM and programming. We pulled his original BCM, identified a common internal fault, and used this exact cloning service. He sent us his module, we sent back the programmed replacement, and he installed it himself in under an hour. Total cost was a fraction of the dealer quote, and his truck was back to normal. This service is a game-changer for both DIYers and independent shops.
Common Signs of a Failing GM BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from the radio, dome lights, or dashboard gauges.
- ✔ A flashing security light or a no-start condition due to anti-theft system issues.
- ✔ False warning messages on the driver information center (e.g., ‘Service Airbag,’ ‘Service StabiliTrak’).
- ✔ Communication-related Diagnostic Trouble Codes (DTCs) such as U0140, U0155, or other ‘U’ codes.
- ✔ Inconsistent operation of exterior lights, including headlights or brake lights.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On most 2015 Tahoe, Suburban, and GM trucks, the BCM is located under the steering column, to the left of the brake pedal. It’s a black box with multiple large electrical connectors.
- ✔ Remove Connectors: Carefully disengage the locking tabs on each wiring harness connector and pull them straight out from the module. Do not force them.
- ✔ Unbolt the Module: Remove the mounting bolts or nuts holding the BCM in place. The module should now be free to remove from the vehicle.
- ✔ Install the New BCM: Seat the replacement module in the mounting bracket and secure it. Reconnect all wiring harnesses, ensuring each one clicks firmly into place.
- ✔ Reconnect Battery: Reattach the negative battery terminal. Start the vehicle and test all body functions (lights, windows, locks, etc.) to confirm the repair.
Important Post-Installation Notes
While our programming makes this a plug-and-play repair, some GM systems require a ‘handshake’ after a new module is introduced. If you see an airbag light, a ‘Setup SDM Primary Key in BCM’ procedure may be needed with a pro-level scan tool. Similarly, a Brake Pedal Position Relearn might be required for perfect brake light and traction control operation. These are simple procedures for any qualified technician. And remember, there’s no core charge—you can keep your old module.

How does this BCM cloning service work?
How does this BCM cloning service work?
After you place your order, we will provide you with shipping instructions. You send your original BCM to us. We then extract the unique programming and transfer it to a replacement module. We ship the newly programmed module back to you, ready for installation. This process ensures all your vehicle’s specific options are retained.
Do I need to get this programmed by a dealer after I install it?
No. The entire point of our service is to eliminate the need for dealer programming. The module you receive from us is pre-programmed with your vehicle’s data, making it a true plug-and-play solution.
What if my airbag light comes on after installation?
This can occasionally happen. It requires a simple ‘Setup SDM Primary Key in BCM’ procedure using a professional diagnostic tool. This syncs the airbag system (SDM) with the new BCM. Any competent local mechanic can perform this for you if needed.
Is there a core charge? Do I have to send my old part back?
There is no core charge. We need your original module to perform the programming service, but once we ship the replacement to you, you do not need to send anything else back. You can keep your original module.
How do I know if my BCM is the problem?
A failing BCM typically causes multiple, seemingly unrelated electrical issues. Common symptoms include problems with power windows, locks, interior/exterior lighting, and warning lights. A full diagnostic scan by a professional is the best way to confirm, but these symptoms are strong indicators.
