Are you dealing with baffling electrical issues in your 2012 Chevrolet Equinox or another compatible GM vehicle? Flickering lights, malfunctioning power windows, a temperamental security system, or even a no-start condition can often be traced back to a single culprit: a failing Body Control Module (BCM). The dealership solution involves a costly new module and expensive programming fees. We offer a smarter, more efficient, and budget-friendly alternative.
This listing is for a comprehensive mail-in programming service. You send us your vehicle’s original BCM, and we transfer all its critical data—including the VIN, mileage, security information, and specific options—to a fully tested, replacement BCM (part number 13580696). The result is a true plug-and-play module, ready for installation the moment you receive it. No trips to the dealer, no additional programming, and no core charge required. You keep your original module.
Common Signs of a Failing Body Control Module
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, locks, or mirrors operating intermittently or not at all.
- ✔ The security system or alarm going off randomly or preventing the car from starting.
- ✔ Instrument cluster gauges behaving abnormally or displaying warning lights without cause.
- ✔ Communication error codes, such as U0140, U0155, or other U-series codes, stored in the system.
- ✔ The engine cranks but refuses to start due to a security immobilizer conflict.
From the Diagnostic Bay: A Real-World Repair Story
A customer brought in their 2012 GMC Terrain with a laundry list of bizarre electrical problems. The horn would honk when they used the turn signal, and the radio would shut off randomly. They had already replaced the battery and checked all the fuses. A quick scan with my diagnostic tool revealed multiple communication loss codes with the BCM. The dealership quoted them over $900 for a new module and the required programming. Instead, we used this exact cloning service. Within a few days, they had the programmed module back. The installation took less than 30 minutes, and every single issue was resolved. This service saved them hundreds of dollars and significant vehicle downtime.
A Straightforward Guide to Your BCM Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work. Wait a few minutes for the system capacitors to discharge.
- ✔ 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. Its location varies on other models (see fitment list), so consult a service manual if you’re unsure.
- ✔ Swap the Modules: Carefully unplug the electrical connectors from your old BCM. They have locking tabs, so be gentle. Unbolt or unclip the old module and remove it. Mount the new, programmed module in its place and securely reconnect all electrical connectors.
- ✔ Power Up and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions: lights, wipers, windows, locks, radio, and horn. Start the vehicle to ensure it runs correctly.
Important Post-Installation Notes
While our programming makes this a plug-and-play solution, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following possibilities:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light and traction control operation.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
How does the mail-in cloning service work?
After you purchase, we will contact you with shipping instructions. You mail your original BCM to us. We then extract the unique data from your module and transfer it to the replacement unit. We ship the newly programmed module back to you, ready for installation.
Will I need to have this 2012 Equinox BCM programmed by a dealer?
No. The entire point of our service is to bypass the need for expensive dealership programming. Because we clone your original data, the vehicle will recognize the replacement module as its own, making it a true plug-and-play installation.
What happens to my old BCM? Do I need to send it back?
You are sending your original BCM to us for the data transfer service. There is no core charge, and we will ship your original, non-functional module back to you along with the programmed replacement unless you instruct us otherwise.
Why do you need my original BCM?
Your original BCM contains the vehicle’s specific VIN, security key data, and other settings that are unique to your car. By cloning this information, we ensure seamless integration and prevent the anti-theft system from disabling the vehicle.
Is the Airbag or Brake Pedal relearn always necessary?
Not always. The need for these procedures depends on the specific vehicle and how its systems react to the module swap. The airbag light sync is only needed if the light comes on after installation. Many customers find no additional steps are required.
