Restore Full Electronic Functionality to Your Vehicle
Is your Cadillac STS or other GM vehicle plagued by strange and unpredictable electrical problems? The Body Control Module (BCM) is the central command center for your car’s body electronics, and when it fails, it can cause a cascade of frustrating issues. This replacement BCM is the definitive solution to restore your vehicle’s systems to perfect working order. We pre-program the module to your vehicle’s specific VIN, ensuring it arrives with the latest GM software updates and is ready for a straightforward installation.
Diagnosing a Failing 2010 STS Body Control Module
A failing BCM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing several of the following symptoms, your BCM is the likely culprit.
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors operating incorrectly or not at all.
- ✔ The security system or keyless entry malfunctioning.
- ✔ The instrument cluster displaying incorrect information or warning lights.
- ✔ Wipers or radio turning on and off unexpectedly.
- ✔ Communication issues when using a diagnostic scan tool.
- ✔ Battery drain when the vehicle is turned off.
A Simple, Reliable Repair Process
Forget expensive dealership visits and complex programming procedures. Our service simplifies the repair. Simply purchase the module and provide us with your vehicle’s VIN. Our technicians will flash the module with the correct software and vehicle-specific configuration. This ensures that when the part arrives, it’s ready to be installed and communicate with your vehicle’s other systems. While the installation is largely plug-and-play, some vehicles may require simple post-installation relearn procedures as outlined below.
Post-Installation Requirements
After installing your new BCM, one or more of the following procedures may be necessary to ensure full functionality:
- 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: To ensure correct brake light and traction control operation, a brake pedal position sensor recalibration may be required on certain models.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It controls functions like power windows, locks, lights, wipers, the security system, and the instrument cluster.
Do I need to get this module programmed?
No. We handle the programming for you before shipment. Just provide your vehicle’s VIN during or after checkout, and it will arrive ready to install with the latest GM software.
Is this a plug-and-play installation?
For most vehicles, it is a direct plug-in replacement. However, as with any BCM replacement, some models may require a simple ‘relearn’ procedure for the brake pedal position sensor or airbag system, which can be done with a professional scan tool.
What happens if my airbag light is on after installation?
This is a common occurrence after a BCM swap. A technician with a compatible scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Will this fix my intermittent electrical problems?
If you are experiencing multiple, seemingly unrelated electrical issues like flickering lights, faulty locks, and erratic wipers, a failing BCM is the most common cause. Replacing it with our programmed unit is the most effective solution.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
