Restore Full Electrical Function to Your Vehicle
Is your 2012 Chevrolet Equinox, GMC Terrain, or other compatible GM vehicle experiencing bizarre electrical problems? Flickering lights, malfunctioning power windows, a dead instrument cluster, or a no-start condition can often be traced back to a single culprit: a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated issues. This listing offers a reliable and straightforward solution: a replacement BCM, part number 13583542, that is professionally programmed with your vehicle’s original data.
The Simple, No-Dealer Solution: Our BCM Cloning Service
Replacing a BCM isn’t as simple as swapping the part. A new or used module from a junkyard must be programmed by a dealership with expensive, specialized tools to match your vehicle’s specific VIN and options. Our unique cloning service completely bypasses this expensive and time-consuming step. Here’s how it works:
- You purchase this service and we provide you with shipping instructions.
- You send us your original, faulty BCM.
- Our technicians extract the critical data (VIN, mileage, key information, security settings) from your module.
- We transfer this data directly onto a fully tested, replacement BCM.
- We ship the newly programmed module back to you, ready for a plug-and-play installation.
This process ensures that the replacement module is a perfect electronic match for your vehicle, preserving all original functions and avoiding the common pitfalls of VIN mismatch and security lockouts.
We had a 2012 GMC Terrain come in that was a complete electrical nightmare. The customer reported that the radio would turn on and off by itself, the turn signals worked intermittently, and sometimes the power door locks wouldn’t respond to the key fob. They had already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication loss codes with various modules. This pointed us directly to the BCM. Instead of a costly dealer replacement and programming, we performed a cloning service just like this one. Once the programmed module was installed, every single issue was resolved instantly. It’s a testament to how a single failing module can wreak havoc on an entire vehicle.
Common Symptoms of a Failing 2012 Equinox BCM
- ✔ Intermittent or non-functional power windows, locks, or mirrors.
- ✔ Erratic behavior from the instrument cluster gauges or warning lights.
- ✔ Headlights, taillights, or interior lights not working correctly.
- ✔ Key fob not being recognized or remote start failure.
- ✔ Vehicle security system engaging randomly or preventing the car from starting.
- ✔ Communication errors with other vehicle modules (DTC U-codes).
- ✔ A/C and climate control system malfunctions.
Installation and Post-Install Considerations
Once you receive your programmed BCM, installation is straightforward. The module is typically located on the left (driver’s) side of the dash. Disconnect the battery, remove the necessary trim panels, unplug the electrical connectors from the old BCM, and swap in the new one. Reconnect everything and you’re done. Because we’ve cloned your original data, no further programming is required for the vehicle to start and run.
Important Note: In some cases, additional synchronization procedures may be needed after installation. These are simple relearn procedures that can be performed with a capable bi-directional scan tool.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required to sync the airbag system.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration might be necessary to ensure proper brake light and traction control operation.

Frequently Asked Questions
What exactly is a BCM cloning service?
We read the essential vehicle-specific data (like the VIN, key codes, and security information) from your original BCM and write it onto a replacement unit. This makes the new module an exact electronic copy, allowing for a simple plug-and-play installation without needing a trip to the dealer for programming.
Do I need to send my original BCM to you?
Yes. We cannot program the replacement module without your original. After you place your order, we will contact you with detailed instructions on how and where to ship your module.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is failing, we can still extract the necessary data. If your module is severely damaged (e.g., by fire or water), please contact us before ordering to discuss options.
How long does the programming service take?
Our typical turnaround time is 1-2 business days after we receive your original module. We then ship the programmed replacement back to you, and you will receive tracking information at that time.
Is this a guaranteed fix for my vehicle’s problems?
This service corrects issues directly caused by a faulty BCM. While the symptoms listed are common indicators of BCM failure, we always recommend a proper diagnosis by a qualified technician to confirm the BCM is the root cause before ordering.
