Tired of Baffling Electrical Problems in Your GM Vehicle?
If you’re dealing with a 2012 Chevy Cruze or another compatible GM model that seems to have a mind of its own—with flickering lights, malfunctioning power windows, a security system that prevents starting, or random warning messages—the root cause is often a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen how a faulty BCM can turn a reliable car into a source of daily frustration. The dealership solution is often a new module followed by a costly programming session. We offer a simpler, more affordable path forward.
This listing is for a comprehensive BCM cloning service. You send us your original BCM, and we transfer all its critical data—including VIN, mileage, and key information—to a fully tested replacement module. The unit you receive back is a true plug-and-play solution, specifically programmed for your vehicle. This process eliminates the need for expensive dealership tools or additional programming, getting you back on the road quickly and confidently.
A Technician’s Notebook: The Cruze with a Ghost
A customer brought in a 2012 Cruze with a laundry list of bizarre issues: the radio would turn off randomly, the interior dome light would stay on, and occasionally, the car just wouldn’t start, with the security light flashing. They had already replaced the battery and checked the alternator. After scanning the vehicle, I found a slew of communication error codes (U-codes) pointing to the BCM. These modules are the central computer for all the car’s comfort and convenience features. On these GM platforms, I’ve seen internal circuit board corrosion from moisture intrusion in the driver’s side footwell cause precisely this kind of electrical chaos. By cloning his original BCM, we provided a permanent fix without the high dealership cost.
Common Signs of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights staying on or not turning on.
- ✔ The anti-theft or security system light is illuminated, causing a no-start condition.
- ✔ Horn honking unexpectedly or not working.
- ✔ Instrument cluster gauges behaving strangely or displaying incorrect information.
- ✔ Communication error codes stored, such as U0140, U0155, or other U-codes.
A Straightforward Guide to Your BCM Replacement
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate the BCM: On the 2012 Chevy Cruze, the Body Control Module is typically found in the driver’s side footwell, behind the kick panel to the left of the pedals. For other models, consult your service manual for the exact location.
- ✔ Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Seat your pre-programmed replacement BCM onto the mounting bracket and securely plug in all the electrical connectors. You should hear a ‘click’ as they lock into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—lights, locks, windows, horn, and wipers—to confirm the repair was successful.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- 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 airbag system with the BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control operation.
Disclaimer: These procedures can vary. We always recommend consulting a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
What exactly is BCM cloning?
BCM cloning is a process where we extract the essential software and vehicle-specific data (like VIN and security information) from your original module and write it directly onto a replacement unit. This makes the replacement BCM an identical twin to your old one, allowing it to work in your car without any additional programming.
Why is this better than buying a new BCM from a dealer?
Our service saves you significant money and hassle. You avoid the high cost of a new module from the dealership and the separate, expensive labor charge for programming. The module you receive from us is ready to install right out of the box.
How does the process work after I purchase?
After you place your order, we will contact you with detailed instructions and a shipping address. You will need to ship your original BCM to us. Once we receive it, we perform the cloning service and ship your ready-to-install replacement module back to you, typically within 1-2 business days.
Do I need to send my keys?
No, you do not need to send your keys. All the necessary immobilizer and key data is stored within the BCM itself, and our cloning process transfers this information to the new module.
What if my original BCM is not communicating?
Even if your BCM is unresponsive, in most cases, we can still extract the necessary data directly from its memory chip. Please contact us with your specific symptoms if you are concerned about the condition of your module.
Is there a core charge?
No, there is no core charge or need to return the replacement part. Our service fee covers the cloning process and the replacement module. You can keep your original, non-working BCM.
