Are you dealing with baffling electrical problems in your 2012 Chevrolet Equinox? Issues like flickering dashboard lights, power windows with a mind of their own, or a security system that prevents your car from starting can often be traced back to a single component: a failing Body Control Module (BCM). As an experienced technician, I’ve seen these modules cause headaches for owners and mechanics alike. This isn’t just a part; it’s the central command center for your vehicle’s body electronics, and when it fails, chaos ensues.
We offer a straightforward, reliable solution. This is a replacement BCM, compatible with part numbers 13584692, 13580696, 123589093, 13588446, and 13583542, that comes ready for installation through our professional cloning service. Forget about expensive dealership visits and the complexities of programming a new module from scratch. Our process is simple: you purchase this service, ship your original BCM to us, and we transfer all the critical data—including VIN, mileage, and key information—to this replacement unit. We then ship the plug-and-play module back to you, ready to be installed. This service restores full functionality and gets you back on the road without the dealership price tag.
Case Study: A Tricky Diagnosis
A customer brought in a 2012 Equinox with a truly bizarre set of symptoms. The radio would turn on by itself, the driver’s side window wouldn’t go down, and occasionally, the horn would honk when they used the turn signal. They had already replaced the battery and checked all the fuses. After connecting my diagnostic tool, I saw multiple communication error codes (U-codes) pointing to the BCM. Instead of a costly new module and hours of programming, we used a cloned BCM. The entire process, from removal to reinstalling the programmed unit, took less than an hour of shop time. The customer drove away with all issues resolved, saving hundreds compared to the dealer quote. This is the power of a properly cloned 2012 Equinox BCM.
Common Signs of a Failing BCM
If your vehicle is experiencing these issues, a faulty BCM is the likely culprit. A failing module can disrupt communication between your vehicle’s electronic systems, leading to unpredictable behavior. Look out for:
- ✔ Erratic or non-functional power windows, locks, and mirrors
- ✔ Dashboard lights flickering, staying on, or not working at all
- ✔ The security or anti-theft system engaging randomly, causing a no-start condition
- ✔ Horn, wipers, or interior lights activating without input
- ✔ Communication-related Diagnostic Trouble Codes (DTCs) such as U0140, U0155, or other U-codes
- ✔ Inconsistent A/C and climate control operation
A Straightforward Guide to Installation
Replacing your 2012 Equinox BCM is a manageable job for a DIY enthusiast or any professional technician. Our cloning service handles the difficult part, leaving you with a simple physical swap.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: In the 2012 Equinox, the BCM is typically located on the left-hand (driver’s) side of the dash, often behind the lower dash panel near the steering column.
- Remove the Old Module: Carefully disconnect the electrical connectors. They have locking tabs that need to be pressed to release. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your newly programmed BCM in the same location. Reconnect all electrical connectors firmly, ensuring they click into place.
- Reconnect Power: Reattach the negative battery terminal.
- Test Functionality: Start the vehicle and test all body functions—windows, locks, lights, wipers, etc.—to confirm the repair. Note the post-installation procedures below.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a quick sync-up after the new module is installed.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This is only necessary if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure correct brake light and traction control operation.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or consult a qualified professional if you are unsure about any step.

Frequently Asked Questions
How does the mail-in cloning service work?
After you place your order, we will contact you with detailed instructions for shipping your original BCM to our facility. Once we receive it, our technicians will transfer its data to the replacement module and ship it back to you, usually within 1-2 business days.
Is this a plug-and-play solution?
Yes, for over 95% of installations. Because we clone your original data, the vehicle will recognize the module, eliminating the need for dealer programming. In rare cases, a simple relearn procedure like for the airbag or brake pedal sensor may be required, as noted above.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is causing major issues, we can still extract the necessary data. If your module has severe water or fire damage, please contact us before ordering to discuss options.
Do I need to send my keys with the module?
No. All the necessary security information is stored within the BCM itself. We clone this data, so your existing keys will work perfectly with the new module upon installation.
Is there a core charge?
No, there is no core charge for this service. You are free to keep your original module after we have completed the cloning process.
Will this fix my specific problem?
This service corrects issues directly caused by a faulty 2012 Equinox BCM. If you’re experiencing the symptoms listed above, it is very likely the solution. Proper diagnosis is key, and we recommend confirming the BCM is the point of failure before ordering.
