End the Electrical Gremlins in Your GM Vehicle
Are you chasing down bizarre electrical issues in your 2012 Chevrolet Equinox? One minute the power windows work, the next they don’t. Maybe your dash lights are flickering, the radio is acting possessed, or worse, you’re facing a no-start condition with the security light flashing. As a technician with over two decades of experience, I’ve seen these exact symptoms hundreds of times, and they almost always point to a failing Body Control Module (BCM). The BCM is the central hub for your vehicle’s body electronics, and when it fails, it creates chaos. This isn’t just an annoyance; it can be a major safety and reliability issue.
This listing offers a straightforward, reliable solution: a replacement Body Control Module, compatible with part numbers including 13588446 and 13580696, that comes fully programmed with your vehicle’s original data. Our professional cloning service eliminates the need for an expensive trip to the dealership for programming. Simply send us your original BCM, and we’ll transfer all the critical information—like VIN, security keys, and specific options—to this replacement unit. We then ship it back to you, ready for a plug-and-play installation. It’s the most efficient way to restore your vehicle’s functionality and peace of mind.
From the Diagnostic Bay: The Case of the Confused Equinox
A customer brought in a 2012 Equinox with a laundry list of complaints: intermittent remote key fob failure, the dome light staying on, and the power locks working only sometimes. They had already replaced the battery and checked all the fuses. A quick scan with my diagnostic tool revealed a slew of communication error codes (U-codes) pointing to the BCM. Instead of just swapping the part and sending them to the dealer for a costly programming session, we used a cloning service just like this one. After a simple swap of the module, every single one of the ghost-like electrical problems vanished. This process saved the customer hundreds of dollars and hours of frustration.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security or anti-theft system light is illuminated, preventing the engine from starting.
- ✔ Inconsistent operation of the horn, windshield wipers, or radio.
- ✔ False warnings appearing on the instrument cluster (e.g., “Service StabiliTrak”).
- ✔ Diagnostic trouble codes (DTCs) related to communication failures, such as U0140, U0155, or other U-codes.
- ✔ The remote keyless entry (RKE) system stops working reliably.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work. This prevents short circuits and protects the vehicle’s sensitive electronics.
- ✔ Locate the BCM: On the 2012 Equinox and GMC Terrain, the BCM is typically located on the left (driver’s) side of the dash, often behind a kick panel or lower dash cover. Consult a service manual for your specific model if you’re unsure.
- ✔ Disconnect and Remove: Carefully unplug all 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 Module: Mount the replacement BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- ✔ Reconnect the Battery: Reattach the negative battery terminal.
- ✔ Perform Post-Install Checks: Start the vehicle and verify that the primary functions (lights, windows, locks) are working correctly. Note the important post-installation procedures below.
Important Post-Installation Steps
While our cloning service makes this a near plug-and-play process, some vehicle systems may require recalibration after the BCM is replaced. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is on after installation, it’s not a fault with the part. The BCM and the Sensing and Diagnostic Module (SDM) need to be re-synced. This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
- Brake Pedal Position Relearn: On some models, the brake pedal position sensor may need to be recalibrated to ensure the brake lights and traction control system function as intended. This also typically requires a diagnostic tool.
Disclaimer: Vehicle systems and procedures can vary. We always recommend consulting a factory service manual or a certified technician for specific guidance.

Frequently Asked Questions
How does the programming service work?
After you purchase, we will contact you with instructions for shipping your original BCM to our facility. Once we receive it, we will clone the data to the replacement module and ship it back to you, typically within 1-2 business days. Tracking information will be provided.
Do I need to send my original BCM? Why?
Yes, you must send us your original BCM. This is essential because your module contains the unique vehicle identification number (VIN), security information, and settings for your car’s specific options. Cloning this data ensures the replacement part works seamlessly without needing dealer programming.
Is there a core charge?
No, there is no core charge for this service. You can keep your original, non-functional module after we have completed the cloning process.
Will this fix my no-start problem?
If your no-start issue is caused by the anti-theft system being triggered by a faulty BCM, then yes, this programmed module should resolve the problem. By cloning your original security data, the new BCM will be recognized by your vehicle’s immobilizer system.
What tools do I need for the installation?
For most models, you will only need basic hand tools like a socket set and screwdrivers to access and remove the BCM. No special electronic tools are required for the physical installation itself. However, a professional scan tool may be needed for post-install procedures like the airbag sync or brake pedal relearn.
