Restore Your Vehicle’s Electrical System with a Plug-and-Play BCM
Are you battling frustrating and unpredictable electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows or locks, a car that won’t start, or random warning messages on your dash are classic signs of 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 affect vehicle security and safety systems. Our pre-programmed 2014-2016 LaCrosse BCM is the reliable, straightforward solution to get your car back to normal without the exorbitant costs and scheduling headaches of a dealership visit.
I once had a 2015 Cadillac SRX in my bay with a truly baffling set of symptoms. The radio would randomly shut off, the driver’s side window wouldn’t work, and the interior lights would stay on, draining the battery overnight. The owner had already replaced the battery and alternator with no luck. After connecting my scan tool, I saw a dozen communication codes (U-codes) pointing to a network failure. The culprit? A failing BCM was corrupting the data bus. Instead of a new, blank module requiring hours of programming, we used a cloned unit. All the vehicle’s original settings were preserved. The moment we plugged it in, every single issue vanished. It’s a perfect example of how a precisely matched BCM is critical for these complex vehicles.
Common Signs of a Failing BCM
If your vehicle is experiencing any of these issues, a faulty BCM is the likely cause. Replacing it with our programmed module can resolve these problems effectively.
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that won’t turn on or off correctly.
- ✔ The security system acting up, causing false alarms or preventing the car from starting.
- ✔ Horn, wipers, or radio functioning intermittently or not at all.
- ✔ Instrument cluster displaying incorrect information or warning lights.
- ✔ Diagnostic trouble codes (DTCs) related to communication, such as U0140, U0155, or other U-codes.
A Straightforward Guide to Our Mail-In Service & Installation
Our process is designed to be simple and eliminate the need for dealer intervention. We transfer the critical data from your original BCM to this replacement unit, making the final installation a direct swap.
- Step 1: Place Your Order. After you purchase, we will contact you with detailed instructions for shipping your original BCM to our facility. Please ensure your contact information is correct.
- Step 2: Ship Your Original Module. Carefully remove your original BCM and send it to us. You are responsible for the initial shipping cost.
- Step 3: We Program Your Replacement. Once we receive your module, our experts will clone all the necessary data to the replacement BCM, typically within 1-2 business days.
- Step 4: Receive Your Ready-to-Install BCM. We ship the programmed module back to you. Tracking information will be provided.
- Step 5: Disconnect the Battery. Before you begin, disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Step 6: Install the Programmed Module. Locate and remove your old BCM (if you haven’t already) and install the programmed replacement. The connectors will only fit one way.
- Step 7: Reconnect the Battery. Re-attach the negative battery terminal. Your vehicle is now ready to start.
Important Post-Installation Notes
In some cases, your vehicle may require additional steps after the new 2014-2016 LaCrosse BCM is installed. This is normal and depends on your vehicle’s specific configuration.
- 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 new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure the brake lights and traction control system function correctly.
Disclaimer: We always recommend consulting a factory service manual or a certified technician if you are unsure about any part of the process.

Frequently Asked Questions
What is a BCM cloning service?
Cloning is a process where we extract the unique, vehicle-specific software—including key data, mileage, and security information—from your original BCM and transfer it directly onto the replacement module. This makes the new part function exactly like your old one, avoiding the need for expensive dealer programming.
Why do I have to send my original BCM to you?
Your original BCM holds the essential data that is paired to your vehicle’s VIN and other electronic modules. By sending it to us, you ensure we can create a perfect data match, resulting in a true plug-and-play solution that works correctly right out of the box.
Is this a plug-and-play part?
Yes, once we program the module with your vehicle’s data, it becomes a plug-and-play part. You simply install it, and it’s ready to go. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake pedal sensor.
What happens if my original BCM is completely dead or unreadable?
In most cases, even with significant internal damage, we can still retrieve the necessary data. If for some reason your module’s data is completely corrupted and unrecoverable, we will contact you to discuss options, which may include a full refund.
Do I need to return my old BCM after installation?
No, there is no core charge for this part. After we clone the data, you can keep your original module.
