Restore Full Functionality to Your GM Vehicle
Are you battling frustrating electrical problems in your 2012 Buick Regal or another compatible GM vehicle? Issues like flickering lights, unresponsive power windows, erratic door locks, or a car that refuses to start can often be traced back to a single component: a failing Body Control Module (BCM). As the central computer for your car’s comfort and convenience features, a faulty BCM can make driving a nightmare. This isn’t just an inconvenience; it can be a significant safety issue. Forget the expensive dealership quotes and the hassle of programming a new module from scratch. We offer a straightforward, reliable solution.
Our service provides you with a fully functional replacement BCM, part number 13580696 (interchangeable with 123589093, 13588446, 13584692, 13583542), that is precisely cloned from your vehicle’s original module. This means all your car’s specific data—including VIN, key information, and security settings—is transferred to the replacement unit. The result? A true plug-and-play part that restores your vehicle’s systems without any need for additional dealership programming.
Common Signs of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or interior lights.
- ✔ The security or anti-theft light stays on, preventing the car from starting.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Dashboard warning lights appearing randomly (e.g., ABS, Airbag, Traction Control).
- ✔ Communication error codes, such as U0140 (Lost Communication With Body Control Module).
- ✔ Wipers or turn signals behaving erratically.
- ✔ Rapid battery drain while the vehicle is off.
A Technician’s Notebook: The Case of the Haunted Equinox
A customer brought in a 2012 Chevy Equinox with a list of symptoms that sounded like something out of a horror movie: the horn would blare at random intervals, the dome lights would flicker, and the driver’s side window had a mind of its own. They had already replaced the battery and checked all the fuses. After connecting my scan tool, I saw a flood of communication errors all pointing back to one source. The BCM wasn’t just failing; it was corrupting the entire data network. By providing a cloned 2012 Regal BCM (the same part number family), we had the vehicle fixed in a day, saving the customer hundreds compared to the dealership’s quote for a new module and programming.
Our Simple Mail-In Cloning Process
Getting your car back on the road is easy. After you place your order, we will contact you with clear, step-by-step instructions for shipping your original BCM to our facility. Please ensure your contact information is up-to-date. Once we receive your module, our expert technicians will perform a full data transfer to the replacement unit. We then ship the ready-to-install BCM back to you, typically within 1-2 business days, and provide you with tracking information. Best of all, there’s no core charge—you can keep your original module.
Straightforward Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any work on the electrical system.
- ✔ Locate the BCM: The location varies by model (see fitment list below). Common spots include behind the driver’s side dash, in the kick panel, or under the center console. A quick search for your specific model will confirm its location.
- ✔ Remove the Old Module: Carefully unplug the electrical connectors. Most have a locking tab that needs to be pressed or lifted. Then, unbolt the module from its mounting bracket.
- ✔ Install the New Module: Seat the replacement BCM in the mounting bracket and secure it. Reconnect all the electrical connectors firmly until they click into place.
- ✔ Reconnect the Battery: Reattach the negative battery terminal.
- ✔ Perform Key-On Cycle: Turn the key to the ‘ON’ position (without starting the engine) for 10-15 seconds to allow the systems to initialize. Start the vehicle and check for proper function of all accessories.
Important Post-Installation Notes
In some cases, additional synchronization procedures may be required after installation. These are simple for any professional shop with a capable diagnostic tool.
- Airbag System Sync: If your airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the airbag system. This is only necessary if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be required to ensure correct brake light operation and to clear any traction control warnings.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or consult with a qualified automotive technician for procedures specific to your vehicle.
