Restore Full Functionality to Your Vehicle’s Electronics
Is your Cadillac, Chevrolet, GMC, or other GM vehicle plagued by mysterious electrical issues? Flickering lights, malfunctioning power windows and locks, a security system that acts on its own, or an unexplained battery drain are all classic signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your car’s body electronics, and when it malfunctions, it can cause a cascade of frustrating and seemingly unrelated problems. This replacement Body Control Module, part number 10382479, is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
Unlike a standard replacement part from a dealership or salvage yard, this BCM arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). This critical step eliminates the need for expensive dealership programming or specialized diagnostic tools for the initial setup. We flash the module with the latest GM software updates, ensuring optimal performance and compatibility. The process is simple: place your order, provide us with your VIN, and we handle the complex programming before shipping the part directly to you.
From the Diagnostic Bay
We once had a 2011 Impala in the shop with a maddening, intermittent no-start condition and a battery that would be dead every few mornings. The owner had replaced the battery and alternator twice. We checked for parasitic draws and found a significant one, but couldn’t isolate it to a single fuse. After hours of tracing wires, we monitored the data bus and noticed the BCM wasn’t allowing other modules to go to ‘sleep’ after the key was off. It was keeping the whole network awake, slowly draining the battery. Swapping in a VIN-programmed BCM like this one solved the problem instantly. It’s a reminder that the BCM’s influence is vast, and a faulty one can create the most confusing symptoms.
Symptoms of a Failing Body Control Module
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from dashboard lights, interior dome lights, or headlights.
- ✔ The security system or keyless entry failing to work correctly.
- ✔ Unexplained parasitic battery drain leading to a dead battery.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Wipers activating on their own or not responding to the switch.
- ✔ Communication errors with other vehicle modules, triggering various warning lights.
The Plug-and-Play Advantage of a Pre-Programmed 2010 STS Body Control Module
The biggest hurdle in replacing a modern vehicle computer is the programming. Our service eliminates this obstacle. By programming the BCM to your VIN before shipment, we ensure that it integrates seamlessly with your car’s existing systems, such as the powertrain control module (PCM), anti-lock brake system (ABS), and instrument cluster. This makes the physical installation a much more straightforward process for you or your mechanic.
Installation and Post-Installation Notes
While the core programming is complete, some vehicles may require minor post-installation procedures, known as relearns, to sync specific subsystems. These are typically simple and can often be performed with a high-end diagnostic scan tool.
- Airbag System Sync: If your airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be required to ensure accurate brake light operation and proper function of the traction control and stability control systems.
Please Note: Specific procedures can vary by vehicle. We always recommend consulting a factory service manual or a qualified technician for detailed guidance.
No Core Charge: You are not required to send your old, faulty module back to us. This saves you time and the cost of return shipping. Keep your original part with no extra fees or hassle.

Frequently Asked Questions
Why do you need my vehicle’s VIN?
The VIN is essential for programming the Body Control Module correctly. It allows us to load the exact software and vehicle-specific options (like keyless entry, power seat type, lighting package, etc.) that your car was built with. This ensures seamless communication with other modules and proper function of all features.
Is this a simple DIY installation?
For someone with moderate mechanical experience, the physical replacement is generally straightforward. The BCM is often located under the dashboard. However, as noted, some vehicles may require additional ‘relearn’ procedures with a professional scan tool after installation. We recommend reviewing a repair manual for your specific model to understand the process fully.
What happens if the airbag light comes on after I install it?
This indicates that the BCM needs to be electronically ‘introduced’ to the airbag module (SDM). A technician with a capable bi-directional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the two components and clear the light.
Will this BCM fix my specific electrical problem?
This module will resolve issues that are directly caused by a faulty BCM. While the symptoms we’ve listed are common indicators, proper vehicle diagnostics are always recommended to rule out other potential causes like bad wiring, grounds, or sensors before replacing any module.
Do I need to send my old part back?
No. This product comes with no core charge. You can keep your original module without any additional cost or obligation to return it.
