Restore Full Functionality to Your Vehicle with a Plug-and-Play Solution
As a technician with over two decades of experience under the hood, I’ve seen firsthand the frustration a failing Body Control Module (BCM) can cause. Your 2012 Chevrolet Equinox or other compatible GM vehicle might feel like it has a mind of its own—windows not working, dash lights flickering, or even a sudden no-start condition that leaves you stranded. These aren’t random glitches; they are classic signs of a BCM failure. The BCM is the central nervous system for your car’s electronics, controlling everything from power locks and interior lighting to security systems and communication between other vital modules. When it fails, chaos ensues.
This isn’t just a replacement part; it’s a complete, hassle-free service. We provide a fully tested BCM, part number 13580696, that is professionally programmed with the data from your vehicle’s original module. This cloning process is the key. It transfers all the specific settings, key information, and vehicle options, making the installation process as simple as swapping the part. You bypass the expensive trip to the dealership and the need for specialized programming tools. We handle the complex part for you, delivering a BCM that is truly ready to install right out of the box.
A Technician’s Notebook: The Case of the Haunted Equinox
A customer brought in a 2012 Equinox with a laundry list of bizarre symptoms. The radio would turn on and off, the power locks worked intermittently, and the biggest complaint was a random no-crank, no-start condition. They had already replaced the battery and checked the starter. After hooking up my diagnostic scanner, I saw multiple communication loss codes (U-codes) pointing to the BCM. Instead of a costly new module and hours of programming at the dealer, we used this exact cloning service. We sent out the original module, got the programmed replacement back, and installed it in under 30 minutes. The electrical gremlins were gone, and the customer was back on the road for a fraction of the dealer’s quote. This is the smart, efficient fix I recommend in my own bay.
Is Your GM Vehicle Showing These BCM Failure Signs?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, your BCM is the likely culprit. This 2012 Equinox BCM is the definitive solution.
- ✔ Unpredictable power windows, door locks, or mirrors.
- ✔ Interior dome lights or dashboard lights staying on or not working at all.
- ✔ The security or anti-theft system preventing the car from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Multiple, unrelated warning lights on the dashboard (e.g., Service StabiliTrak, Service Airbag).
- ✔ Intermittent no-start or no-crank conditions.
- ✔ Diagnostic trouble codes related to lost communication with various modules (e.g., U0140, U0155, U0100).
Your Step-by-Step BCM Installation Guide
Installing your pre-programmed BCM is a straightforward process. For the 2012 Equinox, the BCM is typically located on the left (driver’s) side of the dash, often behind the lower trim panel.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Access the Module: Carefully remove any trim panels or covers necessary to gain access to the BCM. On the Equinox, this is usually on the driver’s side, near the kick panel.
- Disconnect and Remove: 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.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Final Steps: Reinstall any trim panels you removed and reconnect the negative battery terminal. Start the vehicle to confirm that the primary issues are resolved.
Important Post-Installation Note: In some cases, additional steps may be required. If your airbag light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ might be necessary. Always refer to a factory service manual for your specific model’s requirements.

Frequently Asked Questions
How does the programming service work?
After you purchase, we will contact you with instructions to ship your original BCM to us. We then extract the vehicle-specific data and transfer it to the replacement module. This ‘cloning’ process ensures the new BCM is a perfect match for your car’s features and security system, making it plug-and-play.
Do I need to program this BCM after I receive it?
No. The module arrives pre-programmed and ready for installation. Our service eliminates the need for any additional programming with expensive dealer tools, saving you time and money.
What if my airbag light is on after installation?
This can happen occasionally. It means the new BCM needs to be synchronized with the airbag system’s Sensing and Diagnostic Module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed by a mechanic with a professional-grade diagnostic tool to resolve this.
Is there a core charge for my old BCM?
No, there is no core charge. While we need your original module to perform the programming service, you are welcome to keep it afterward if you wish.
How can I be sure the BCM is my problem?
Common symptoms include erratic behavior of lights, locks, and windows, or intermittent no-start conditions. A professional diagnosis with a scan tool that can read BCM codes is the best way to confirm the failure.
Where is the BCM located on a 2012 Chevy Equinox?
On the 2012 Equinox, the Body Control Module is typically found on the driver’s side of the dashboard, behind the lower trim panel near the kick panel area.
