End the Electrical Chaos in Your GM Vehicle
Is your car acting possessed? Flickering lights, power windows with a mind of their own, a security light that won’t turn off, or worse—a car that refuses to start? These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it goes bad, it can cause a cascade of confusing and frustrating problems. In my 20+ years of diagnostics, I’ve seen faulty BCMs send both owners and technicians on wild goose chases, replacing perfectly good parts. This service is the direct, reliable solution.
We take the guesswork and high dealership costs out of the equation. This isn’t just a part in a box; it’s a comprehensive solution. By sending us your original BCM, you allow us to perform a precise data transfer to this fully tested replacement unit. This cloning process copies all your vehicle’s essential information—like key programming, security settings, and specific options. The result? You receive a module that is truly plug-and-play. No need for an expensive trip to the dealership for programming. You save time, money, and the headache of a tow bill.
A Technician’s Notebook: The Malibu That Wouldn’t Cooperate
A 2013 Chevy Malibu came into a partner shop with a bizarre set of symptoms. The radio would randomly shut off, the driver’s side window wouldn’t work, and occasionally the car wouldn’t start, showing a ‘Service Theft Deterrent System’ message. The mechanic had already checked the battery and grounds. Scans showed intermittent communication loss with the BCM (U0140). Instead of just replacing the module and forcing the customer to pay for programming, they sent it to us. We cloned the original data onto a replacement BCM. The mechanic plugged it in, and every single issue was resolved instantly. No relearning, no programming—just a running, happy car. This is the power of a properly cloned module.
Common Signs of a Failing GM BCM
If you’re experiencing any of the following, a faulty BCM is the likely culprit. A failing module can often set communication codes like U0140, U0155, or other B-series codes.
- ✔ Intermittent or non-functional power windows, locks, or mirrors.
- ✔ The security or anti-theft light stays on, preventing the car from starting.
- ✔ Erratic interior or exterior lighting behavior (lights staying on or not turning on).
- ✔ Horn, wipers, or radio functioning incorrectly or not at all.
- ✔ False warning messages on the instrument cluster.
- ✔ A no-start condition where the engine cranks but won’t fire up.
Your Straightforward BCM Installation Guide
Installing your pre-programmed 2013 Regal BCM is designed to be a simple process. The location varies slightly by model, but it’s typically found in the driver’s or passenger’s side footwell area or behind the dash.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: Find the original BCM. On a 2013 Regal, it’s usually on the left-hand side of the dash. For other models, check the fitment list for common locations.
- Disconnect and Remove: 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 the replacement BCM into the mounting bracket and securely plug in all the electrical connectors. You should hear a click as they lock into place.
- Reconnect Power: Reconnect the negative battery terminal.
- Perform Final Checks: Start the vehicle and test all body functions—windows, locks, lights, wipers, etc. Note the post-installation procedures below, as some may be required.
Important Post-Installation Steps
While our cloning makes this a plug-and-play repair, some GM systems require a ‘handshake’ after a new module is introduced. Be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated 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: On some models, a brake pedal position sensor relearn may be required to ensure your brake lights and traction control system function correctly.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a qualified professional if you are unsure about any step.

Frequently Asked Questions
Frequently Asked Questions
How does the cloning service work?
After you place your order, we’ll contact you with instructions to ship your original BCM to us. Once we receive it, we extract the unique data and transfer it to the replacement module. We then ship the plug-and-play replacement back to you, typically within 1-2 business days.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM isn’t functioning in the vehicle, we can still recover the necessary data directly from the memory chip on the circuit board. Contact us with your specific situation if you have concerns.
Do I need to send my keys?
No. Because we are cloning your original module’s data, the replacement BCM will already recognize your existing keys. This is a major benefit over dealer replacement, which requires expensive key reprogramming.
Is this a guaranteed fix for my car’s problems?
This BCM will fix any issue directly caused by a faulty BCM. While the symptoms listed are very common for BCM failure, we always recommend a proper diagnosis by a qualified mechanic to confirm the BCM is the root cause before purchasing.
Do I have to return my old BCM?
No, there is no core charge for this service. You only need to send your original BCM to us for the data cloning service. You can keep your original module after the service is complete.
