Tired of Unpredictable Electrical Problems in Your GM Vehicle?
As a technician with over two decades of experience, I’ve seen firsthand how a failing Body Control Module (BCM) can turn a reliable car into a source of daily frustration. One minute your power windows work, the next they don’t. Your dash lights might flicker like a concert, or worse, the car won’t start at all. These aren’t just annoyances; they’re symptoms of a central nervous system failure in your vehicle. This isn’t a problem you have to live with, and you don’t need an expensive trip to the dealership to solve it.
We offer a straightforward, reliable solution: a replacement BCM with a professional cloning service. This service is designed for both seasoned mechanics and DIY enthusiasts who want a permanent fix without the hassle of dealer-level programming. By precisely transferring the data from your original module to this replacement unit, we deliver a true plug-and-play component. This ensures your vehicle retains its specific key information, security settings, and options, making the installation process as simple as swapping the part. A faulty BCM can be the root cause of many hard-to-diagnose issues, and installing our pre-programmed 2012 Cruze BCM is the definitive way to restore your car’s proper function.
A Technician’s Notebook: The Case of the Confused Cruze
A 2012 Chevy Cruze came into my bay with a laundry list of bizarre electrical complaints. The owner reported intermittent no-starts, the radio would randomly shut off, and the turn signals had a mind of their own. A scan showed a handful of communication error codes (U-codes), pointing towards a network issue. After checking the main power and ground connections, my diagnostic path led straight to the BCM. Instead of quoting the customer for a new module plus hours of programming and setup fees at the dealer, we opted for a cloned BCM. Once the cloned module arrived, the physical swap took less than 30 minutes. The car started right up, every function was restored, and all communication codes were gone. It’s a perfect example of how the right part, correctly prepared, saves time, money, and diagnostic headaches.
Common Signs of a Failing BCM
If you’re experiencing any of the following, a faulty BCM is the likely culprit. This part is the solution for a wide range of electrical issues, including communication codes like U0140, U0155, and other network-related faults.
- ✔ Intermittent or non-functional power windows, door locks, or interior/exterior lights.
- ✔ Erratic behavior from the instrument cluster, gauges, or warning lights.
- ✔ Remote key fob not working or working sporadically.
- ✔ Vehicle security system issues or false alarms.
- ✔ Inconsistent starting or a complete no-start condition.
- ✔ Problems with the HVAC (heating and air conditioning) controls.
- ✔ Communication errors with other modules on the vehicle’s network.
A Straightforward Guide to Installation
Our cloning service makes installing your replacement 2012 Cruze BCM simple. Since all the necessary data is transferred from your original unit, you won’t need a trip to the dealer for programming.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate Your BCM: On the 2012 Cruze, the BCM is typically found in the driver’s side kick panel area. For other models, its location can vary (see fitment list for common locations).
- Remove the Original Module: Carefully unplug the electrical connectors. Most have a locking tab that needs to be pressed or lifted. Once disconnected, unbolt the module from its mounting bracket.
- Install the Replacement: Mount the new, pre-programmed BCM in the same location. Securely reconnect all electrical connectors, ensuring they click into place.
- Reconnect the Battery: Reattach the negative battery terminal.
- Test All Functions: Start the vehicle and test all body-related functions: lights, windows, locks, wipers, and radio to confirm the repair.
- Perform Post-Install Procedures (If Needed): In some cases, an airbag light may appear or brake pedal position may need to be relearned. These procedures require a professional scan tool. See our notes below for more details.
Important Post-Installation Information
While our goal is a 100% plug-and-play experience, certain vehicle systems may require a quick sync-up after the BCM is replaced. This is normal and easily addressed:
- Airbag System Sync: If the airbag warning light is on after installation, a scan tool procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the modules and clear the light.
- Brake Pedal Position Relearn: On some models, a brake pedal sensor recalibration might be necessary to ensure correct brake light operation and stability control function.
Always consult a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we will provide instructions for shipping your original BCM to us. Once we receive it, our technicians will transfer all the critical vehicle-specific data (like VIN, mileage, and key information) to the replacement BCM. We then ship the plug-and-play module back to you.
Do I really need to send you my original BCM?
Yes. This is essential for the cloning process. Without your original module, we cannot transfer the unique data required for the replacement to be plug-and-play in your specific vehicle.
Is this module truly plug-and-play?
Yes, in over 98% of cases. The cloning process eliminates the need for dealer programming. In rare instances, a simple relearn procedure, like for the airbag system or brake pedal sensor, may be needed, which can be done with a standard professional scan tool.
What if my airbag light comes on after installation?
This is a known possibility and is not a defect. It simply means the new BCM needs to be synced with the airbag module (SDM). A mechanic with a capable scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
How long does the entire process take?
We typically clone and ship your replacement module within 24-48 hours of receiving your original BCM. The total time will depend on shipping times to and from our facility. We will send you a tracking number once it’s on its way back to you.
Is there a core charge for my old part?
No, there is no core charge. We need your original module for the data transfer service, but you are not required to leave it with us. However, most customers find it convenient to not have the old part returned.
