Tired of Baffling Electrical Problems in Your GM Vehicle?
If you’re dealing with flickering lights, a car that won’t start, power windows with a mind of their own, or strange warning messages on your dash, the culprit is often a failing Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, a faulty BCM can cause a cascade of frustrating and seemingly unrelated issues. For many owners of a 2012 Equinox, a failing BCM isn’t just an annoyance; it’s a roadblock. The dealership solution often involves a brand new, expensive module followed by costly programming fees, leaving your vehicle stranded for days.
We offer a smarter, more efficient solution. This is a professionally prepared BCM, compatible with part numbers including 13584692 and 13580696, that is delivered to you ready for installation. We achieve this through our specialized cloning service. Simply send us your original BCM, and we will transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to this replacement unit. The result? A true plug-and-play module that restores full function to your vehicle without any need for dealer intervention. This service is the definitive fix for your 2012 Equinox BCM issues.
Case Study: A Tricky Diagnosis
A few months back, a 2012 GMC Terrain (which uses the same BCM as the Equinox) was towed into my shop. The customer was at their wit’s end. They had intermittent no-start conditions, the radio would randomly turn off, and the security light was flashing. They had already replaced the battery and alternator at another shop to no avail. After hooking up my scan tool, I saw a flurry of U-codes, specifically a U0140 (Lost Communication With Body Control Module). This pointed directly to the BCM. Instead of a costly new unit, we used our cloning service. Within a few days, the customer had a working vehicle again, saving them hundreds compared to the dealership quote. This is a classic BCM failure scenario I’ve seen countless times.
Common Signs of a Failing GM BCM
If your vehicle is experiencing these issues, a faulty BCM is the likely cause. Look out for communication-related Diagnostic Trouble Codes (DTCs) like U0140, U0155, or B1001.
- âś” Intermittent or complete no-start condition
- âś” Power windows, locks, or mirrors not working correctly
- âś” Interior or exterior lights flickering or staying on
- âś” Security system faults or anti-theft light illuminated
- âś” Inaccurate gauge readings on the instrument cluster
- âś” Radio or infotainment system malfunctions
Your Straightforward BCM Installation Guide
Installing your pre-programmed BCM is designed to be a direct replacement. While locations vary slightly, the process is generally similar across compatible models.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On the 2012 Equinox and Terrain, the BCM is typically found 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 vehicle’s location.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the exact same location. Reconnect all electrical connectors securely.
- Reconnect Battery: Reattach the negative battery terminal.
- Post-Installation Checks: Start the vehicle and test all functions controlled by the BCM (lights, windows, locks, etc.). Note that some vehicles may require additional procedures as outlined below.
Important Post-Installation Information
Our cloning service handles the vast majority of programming needs. However, in some cases, vehicle systems may require a ‘handshake’ with the new BCM. This is normal and can typically be performed with a bi-directional scan tool.
- Airbag System Sync: If the airbag light is on after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and stability control operation.
Disclaimer: Always consult a factory service manual or a qualified technician for vehicle-specific procedures. No core charge is required; you can keep your original module.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we will provide you with instructions to ship your original BCM to us. Once we receive it, our technicians extract the unique data and transfer it to the replacement module. We then ship the ready-to-install BCM back to you.
Do I need to program this BCM at the dealer?
No. Our cloning service makes this a plug-and-play solution. All the necessary vehicle-specific programming is done by us before we ship the part to you, saving you time and money.
Is this the correct part for my 2012 Equinox BCM?
Yes, this module is a confirmed fit for the 2012 Chevrolet Equinox and is compatible with part numbers 13584692, 13580696, and others listed in the fitment chart.
What if my airbag light comes on after installation?
This can occasionally happen as the vehicle’s safety systems perform a self-check. A simple ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool will resolve this and sync the systems.
Do I have to send my old BCM back? Is there a core charge?
You must send your original BCM to us for the cloning service, but there is no core charge, and you are not required to return it after receiving the programmed replacement.
