Is Your Chevy Cruze Experiencing Strange Electrical Issues?
The Body Control Module, or BCM, is the central command center for your vehicle’s electronic accessories. In a 2012 Chevy Cruze, it manages everything from your power windows and door locks to the interior lights, security system, and even communication between other vital modules. When the BCM begins to fail, it can create a cascade of confusing and frustrating problems that can seem unrelated, making diagnosis a challenge.
From the Diagnostic Bay
We once had a 2011 Buick LaCrosse (which uses a similar BCM) come into the shop with the radio turning on and off by itself and the power locks cycling while driving. The customer was convinced the vehicle was possessed. After checking the main power and ground connections to the BCM, we confirmed the module itself had an internal fault. Instead of a costly trip to the dealer for a new module and programming, we provided a cloned BCM. The customer was able to install it themselves in under an hour, solving all the ghost-in-the-machine problems instantly.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior dome lights or exterior lights staying on or not turning on.
- ✔ The security system light flashing, or the vehicle refusing to start due to a perceived theft attempt.
- ✔ Horn honking randomly or failing to work when pressed.
- ✔ Inaccurate gauge readings or warning lights on the instrument cluster.
- ✔ No communication with the BCM when using a diagnostic scan tool.
The Simple, Plug-and-Play Solution: Our 2012 Cruze BCM Service
Forget expensive dealership visits and the hassle of coordinating programming and key learning procedures. Our professional programming service makes this repair straightforward and affordable. We take all the critical data from your original, failing BCM—including VIN, key information, and vehicle-specific options—and transfer it directly to a replacement unit. The result is a true plug-and-play module that is ready for installation the moment you receive it.
How It Works:
- Place Your Order: Complete your purchase through our secure checkout.
- We’ll Contact You: We will reach out with clear instructions on how to ship your original BCM to our facility.
- We Program Your Part: Once we receive your module, our technicians will perform the data transfer to the replacement BCM, typically within 1-2 business days.
- Receive Your Ready-to-Install BCM: We ship the programmed module back to you. Simply install it, and your vehicle’s body electronics will be fully restored.
Installation and Post-Install Notes
Installation is as simple as disconnecting the battery, accessing the BCM (typically located in the driver’s side kick panel on the Cruze), swapping the modules, and reconnecting the battery. Because we’ve handled all the programming, no further steps are usually required. However, in some GM vehicles, certain systems may need to be re-synced after the new module is installed.
- Airbag System Sync: If your airbag warning light is on after installation, a simple “Setup SDM Primary Key in BCM” procedure may be needed. This is a quick task for any shop with a professional-grade scan tool.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control function, a brake pedal position sensor recalibration might be necessary. This is also a simple procedure performed with a scan tool.

Frequently Asked Questions
How does this cloning service work?
You send us your original BCM. We extract the unique data (like VIN and key codes) and flash it onto a fully functional replacement BCM. We then send the replacement module back to you, ready to install without any further programming.
What is the total turnaround time?
Our in-house programming service is completed within 1-2 business days of receiving your original module. The total time will depend on shipping times to and from our facility.
Do I need to program this BCM after I receive it?
No. The module arrives fully programmed and ready for installation. This is a plug-and-play solution that eliminates the need for a trip to the dealership.
Will my original keys and remote fobs still work?
Yes. Because we transfer all the data from your original module, the replacement BCM will recognize your existing keys and remotes automatically.
What if the airbag light comes on after installation?
This is uncommon, but if it happens, it means the BCM and the airbag module (SDM) need to be re-synced. A repair shop with a professional scan tool can perform the “Setup SDM Primary Key in BCM” procedure in a few minutes to resolve this.
Is this service compatible with other GM vehicles?
Yes, this BCM and programming service fits a wide variety of GM models, including the LaCrosse, Volt, SRX, Terrain, Equinox, Camaro, and Orlando. Please check the fitment list and your original part number to confirm.
