Restore Your Vehicle’s Brain, Not Just a Part
Are you chasing electrical gremlins in your 2015 Chevy Tahoe or another GM vehicle? Flickering lights, power windows with a mind of their own, a horn that won’t stop, or a security light that keeps you from starting the engine are all classic signs of a failing Body Control Module (BCM). As the central command center for your vehicle’s comfort and convenience features, a faulty BCM can make driving a frustrating and unpredictable experience. This isn’t just an inconvenience; it can affect everything from your interior lighting to your vehicle’s security system.
Instead of facing a costly trip to the dealership for a new module and expensive programming fees, we offer a straightforward, reliable solution. This is a fully tested replacement BCM, part number 13594692, that we professionally program using the data from your original unit. This cloning process ensures that all your vehicle’s specific settings, key data, and option configurations are perfectly transferred. The result is a true plug-and-play module, eliminating the need for any additional programming or calibration with a dealership scan tool. Getting your truck or SUV back to normal has never been simpler.
A Technician’s Notebook: The Haunted SUV
I remember a 2015 Suburban that came into my shop with a list of symptoms that sounded like something out of a horror movie. The owner said the dome lights would flicker randomly, the radio would shut off, and sometimes the power locks would cycle on their own while driving. He had already replaced the battery and checked the main grounds. After hooking up my diagnostic tool, I saw a flood of ‘Lost Communication’ codes, specifically a U0140 with the BCM. This pointed directly to the vehicle’s electronic nerve center. By installing a cloned 2015 Tahoe BCM (the Suburban uses the same module), we restored all functions perfectly in under an hour. It’s a common failure, but our cloning service makes the fix fast and permanent.
Is Your Vehicle Showing These Symptoms?
A failing BCM can cause a wide range of confusing issues. If you’re experiencing any of the following, your BCM is the likely culprit:
- âś” Erratic or non-functional power windows, locks, or mirrors.
- âś” Interior or exterior lights flickering, staying on, or not working at all.
- âś” The security or anti-theft light is illuminated, preventing the engine from starting.
- âś” The horn or alarm sounds off unexpectedly.
- âś” Wipers operate intermittently or won’t turn off.
- âś” Communication error codes, such as U0140, stored in other modules.
- âś” False warnings on the driver information center (DIC).
A Straightforward Guide to Installation
Our cloning service makes this a job most DIYers or any professional shop can handle with ease. Since the programming is already done, you just need to swap the modules.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On most compatible trucks and SUVs like the 2015 Tahoe, the BCM is located under the driver’s side of the dashboard, near the steering column. It’s a black box with multiple large electrical connectors.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely plug in all the electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting) and test all body functions: lights, windows, locks, wipers, etc.
Important Post-Installation Notes
While our goal is a 100% plug-and-play experience, modern vehicle systems are highly integrated. In some cases, minor follow-up procedures may be needed:
- Airbag System Sync: If your airbag warning light is on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the airbag system with the new BCM and can be performed by a shop with a professional-grade diagnostic tool.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be necessary to ensure perfect operation of the brake lights and stability control systems.
Disclaimer: Always consult a factory service manual for your specific vehicle for detailed instructions and torque specs. These steps are a general guide.

Frequently Asked Questions
Frequently Asked Questions
How does this cloning service work?
It’s simple! After you purchase, we’ll provide instructions for shipping your original BCM to us. Once we receive it, our technicians will extract the unique data and transfer it to the replacement unit. We then ship the plug-and-play module back to you, typically within one business day.
Do I need to program this 2015 Tahoe BCM?
No. The main benefit of our service is that the module arrives at your door fully programmed and ready for installation. This saves you from having to pay for expensive dealership programming.
Do I need to send my keys or other modules?
No, we only need your original Body Control Module. The key and security information is contained within the BCM itself, which we will transfer to the new unit.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM has failed, we can still recover the necessary data. Please contact us with your specific situation if you believe your module is non-responsive.
Is there a core charge?
No, there is no core charge or need to return your old part after the service is complete. You can keep your original module.
What happens if the airbag light comes on after I install it?
This is a known possibility on some GM vehicles. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag module. A repair shop with a capable scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
