Is Your 2012 Equinox Acting Possessed?
As a technician with over two decades of experience, I’ve seen it all. The frantic calls about a vehicle’s lights flickering randomly, the power windows having a mind of their own, or the security system preventing the car from starting. These aren’t ghosts in the machine; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it starts to go, it can cause a cascade of confusing and frustrating problems. For many owners, the next step is a dreaded, expensive trip to the dealership for diagnostics and programming. But it doesn’t have to be that way.
This is a complete, ready-to-install solution for your vehicle. We provide a replacement BCM with part number 13580696 that is professionally programmed with the data from your vehicle’s original module. This cloning service makes the replacement process incredibly straightforward. You simply send us your original BCM, we transfer all the critical vehicle-specific information to the replacement unit, and ship it right back to you, ready for installation. This eliminates the need for expensive dealer-specific scan tools and programming subscriptions, putting the power back in your hands.
Case Study: The Phantom Battery Drain
A customer brought in a 2012 Terrain (which uses the same BCM) with a battery that would die overnight. They had already replaced the battery and alternator, but the problem persisted. After checking for parasitic draws, we noticed the interior lights would faintly glow long after the car was off. A standard scan showed no hard codes, but live data monitoring revealed the BCM wasn’t entering its ‘sleep’ mode correctly. Instead of a costly diagnostic hunt, we confirmed the BCM was the culprit. A cloned module like this one had the vehicle fixed in an afternoon, saving the customer hundreds compared to a dealer visit.
Is Your Equinox Exhibiting These Strange Symptoms?
A failing BCM can manifest in numerous ways. If you’re noticing any of the following, it’s a strong indicator that your BCM needs attention:
- ✔ Erratic interior or exterior lights (flickering, staying on, or not working at all).
- ✔ Power windows, locks, or mirrors operating intermittently or not at all.
- ✔ The horn honking unexpectedly or the alarm system malfunctioning.
- ✔ Instrument cluster gauges behaving erratically or warning lights appearing without cause.
- ✔ Communication error codes, often starting with ‘U’ (e.g., U0140), indicating a loss of communication with the BCM.
- ✔ A no-start condition where the security or anti-theft light is flashing.
A Straightforward Guide to Your BCM Installation
Our cloning service makes this repair accessible for both DIY enthusiasts and professional mechanics. Since the programming is done, installation is a physical swap.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On the 2012 Equinox, the BCM is typically located on the left (driver’s) side of the dash, often behind the lower trim panel near the fuse box.
- Remove the Old Module: Carefully disconnect the electrical connectors. Press the release tabs firmly and pull straight out to avoid damaging the pins. Then, unbolt or unclip the module from its mounting bracket.
- Install the New BCM: Mount the replacement BCM you received from us and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Final Checks: Start the vehicle and test all body functions—lights, locks, windows, etc. Note that some post-install procedures may be necessary.
Important Note on Post-Installation: 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. Additionally, a ‘Brake Pedal Position Relearn’ might be necessary to ensure proper brake light and traction control function. Always consult a factory service manual for vehicle-specific details.

Frequently Asked Questions
What exactly is a Body Control Module (BCM)?
The BCM is a computer in your car that controls and monitors a wide range of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, the security system, and more. It’s the command center for your vehicle’s creature comforts and security.
Why does my original BCM need to be sent in?
Your original BCM contains vital, vehicle-specific data, including the Vehicle Identification Number (VIN) and security information. By cloning this data to the replacement module, we ensure it’s a true plug-and-play part, saving you from a costly and complicated programming procedure at a dealership.
What is the process after I place my order?
After you complete your purchase, we will contact you with detailed instructions and a shipping address. You will need to carefully package and ship your original BCM to us. Once we receive it, we will perform the cloning service and ship your new, programmed BCM back to you, typically within 1-2 business days.
Will I need any special tools for installation?
No special programming tools are required. Basic hand tools (like a socket set and trim removal tools) are all that’s typically needed to physically swap the module. The complex programming work is handled by us before you even receive the part.
What if the airbag light is on after I install it?
This can happen occasionally. It means the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). This requires a ‘Setup SDM Primary Key’ procedure, which can be done by most professional repair shops with a high-level diagnostic scan tool.
Is there a core charge for my old part?
No, there is no core charge. We only need your original module for the data transfer service. You are welcome to keep your original, non-functional module after the service is complete.
