Are you experiencing frustrating and unpredictable electrical problems in your GM vehicle? Issues like flickering lights, malfunctioning power windows and locks, or a security system that acts up on its own are common signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing symptoms. This replacement BCM is the definitive solution to restore full functionality and peace of mind to your driving experience.
This isn’t just a part; it’s a complete, ready-to-install solution. We take the hassle and high cost out of the repair process. Before we ship your module, our experts will program it with the latest GM software updates, specifically matched to your vehicle using its unique VIN. This means no expensive trips to the dealership for programming—it arrives at your door ready for installation.
We had a 2010 Cadillac STS come in with a laundry list of bizarre issues. The dome lights would stay on, the driver’s side window wouldn’t go down, and the key fob worked intermittently. The owner had already replaced the battery and checked fuses with no luck. After connecting our diagnostic tool, we saw multiple communication errors pointing towards the BCM. Instead of a complex and costly diagnostic and programming session at a dealer, the owner opted for one of our pre-programmed modules. The installation was straightforward, and as soon as the battery was reconnected, every single electrical gremlin was gone. It’s a perfect example of how a failing BCM can mimic a dozen other problems, and how the right part can be a simple, effective fix.
Diagnosing Your 2010 STS Body Control Module
A faulty BCM can be difficult to pinpoint because its symptoms often overlap with other component failures. However, if you’re experiencing several of the following issues simultaneously, the BCM is the most likely cause.
Common Symptoms of a Failing BCM:
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors not working correctly or at all.
- ✔ Vehicle security system or keyless entry malfunctions.
- ✔ Wipers operating randomly or not responding to the switch.
- ✔ Instrument cluster gauges behaving erratically or displaying incorrect information.
- ✔ Warning lights (like the airbag or brake light) staying on without a clear cause.
- ✔ The vehicle not starting due to security system communication failure.
By replacing your old, malfunctioning unit with this professionally programmed 2010 STS Body Control Module, you can confidently resolve these issues. We ensure this part is a direct replacement for a wide range of original equipment part numbers, making it a versatile solution for many GM cars, trucks, and SUVs.
Installation and Post-Install Procedures
After you receive your VIN-programmed BCM, the physical installation is typically a direct swap. However, on modern vehicles, other systems may need to be re-synced with the new module. Please be aware of the following potential procedures:
- 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 proper function of the brake lights and stability control systems.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle responsible for managing and controlling various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It acts as a central hub for these functions.
Do I need to get this programmed?
No. We handle the programming for you before shipment. Simply provide us with your vehicle’s VIN during checkout, and we will flash the module with the correct software for your specific vehicle, making it ready for installation.
How do I know if my BCM is the problem?
Diagnosing a BCM can be tricky, but common signs include multiple, unrelated electrical issues happening at once. For example, if your power locks, interior lights, and radio all start acting erratically, the BCM is a prime suspect.
What information do you need from me?
After you complete your purchase, we will need your 17-digit Vehicle Identification Number (VIN). This is essential for us to program the BCM correctly for your vehicle’s specific options and configuration.
Are any other steps needed after installation?
In some cases, yes. You may need to perform a ‘relearn’ or ‘sync’ procedure for systems like the airbags or brake pedal position sensor. This often requires a professional-grade scan tool and ensures all vehicle systems communicate properly with the new BCM.
