Tired of Electrical Gremlins in Your GM Vehicle?
Is your Buick Regal, Chevy Cruze, or GMC Terrain acting possessed? Flickering lights, power windows with a mind of their own, a security system that won’t cooperate, or even a no-start condition can all point to one culprit: a failing Body Control Module (BCM). As the central command for your car’s body electronics, when the BCM goes down, it can cause a cascade of frustrating and seemingly unrelated problems. The dealership solution often involves a brand new, expensive module followed by hours of programming fees. We offer a smarter, more direct solution.
This is a comprehensive Cloning Service for your BCM. You simply send us your original module, and we transfer all its vital data—including immobilizer information, key programming, and vehicle-specific options—to this fully tested replacement unit. We then ship both your original module and the ready-to-install replacement back to you. The result? A true plug-and-play fix that saves you hundreds of dollars and eliminates the headache of a trip to the dealer.
Case Study: A Tricky Diagnosis
A customer brought in a 2014 Chevy Cruze that was driving them crazy. The car would randomly fail to start, the radio would shut off, and the interior lights would flicker. They had already replaced the battery and checked the alternator. After connecting my diagnostic scanner, I saw a flurry of U-codes (U0140, U0155), indicating a loss of communication between various modules. In my 20+ years of experience, these network-wide communication faults often lead back to the BCM. Instead of a costly new module and a complex programming session, we performed a cloning service just like this one. The customer had their car back the next day, fully functional, for a fraction of the dealership’s quote. This service directly addresses the root cause without unnecessary costs.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior dome lights or exterior lights staying on or not working at all.
- ✔ The security system light flashing, preventing the car from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Wipers activating on their own or not responding to the switch.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0100, or B-series codes.
- ✔ Intermittent no-start condition where all other components (battery, starter) test good.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate Your BCM: The location varies by model. Common spots include behind the driver’s side kick panel (Cruze, Malibu), under the dash (Regal, SRX), or even in the engine bay (Volt). Refer to your owner’s manual or a reliable online resource for your specific vehicle.
- ✔ Remove the Original Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the BCM from its mounting bracket.
- ✔ Install the New Module: Seat the 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 Power: Reattach the negative battery terminal and tighten it securely.
- ✔ Test and Verify: Start the vehicle and test all body functions—lights, windows, locks, wipers, etc. Note that some post-install procedures may be required as outlined below.
Important Post-Installation Notes
Because we’ve cloned your original data, most functions will work immediately. However, on some GM vehicles, specific security handshakes need to be re-established:
- Airbag System Sync: If your 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 new BCM.
- Brake Pedal Position Relearn: To ensure accurate brake light operation and traction control function, a brake pedal position sensor recalibration might be necessary on certain models.
Always consult a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
What exactly is a ‘Cloning Service’?
Cloning is a process where we perform an exact, bit-for-bit data transfer from your original BCM to the replacement unit. This copies all the critical vehicle-specific information, including the VIN, mileage, key data, and optional feature settings. This makes the replacement module plug-and-play, avoiding any need for dealership programming.
Why is this better than buying a new BCM from a dealer?
Our service saves you significant time and money. A new BCM from the dealer is not only expensive but also comes ‘blank’. It requires special tools and a subscription to the manufacturer’s network to be programmed to your vehicle, adding hundreds in labor costs. Our cloning service bypasses that entire step.
Do I get my original module back?
Yes, absolutely. We always ship your original module back along with the newly programmed replacement. We do not keep your old part.
What if my airbag light is on after I install it?
This can happen on some models as a security measure. It simply means the BCM and the airbag module (SDM) need to be re-synchronized. A qualified mechanic with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
How does the process work after I purchase?
After you place your order, we will contact you with detailed instructions on how and where to ship your original BCM. Please ensure your contact information is correct at checkout. Once we receive your module, we typically complete the cloning service and ship both units back to you within 1-2 business days.
