Is Your Vehicle Plagued by Baffling Electrical Issues?
If you’re dealing with flickering lights, power windows and locks with a mind of their own, or a security system that won’t cooperate, a failing Body Control Module (BCM) is likely the culprit. The BCM is the central command center for your vehicle’s body electronics, and when it malfunctions, it can cause a cascade of frustrating and unpredictable problems. Instead of spending a fortune at the dealership, get the definitive, ready-to-install solution right here.

Expert Insight: The BCM is Your Car’s Nervous System
Think of the BCM as the vehicle’s central nervous system. It doesn’t just turn things on and off; it manages communication between dozens of other computers, from the engine controller to the radio. That’s why a generic, non-programmed module won’t work. Our VIN-specific programming ensures that your new BCM knows whether you have a sunroof, heated seats, or a specific trim package, allowing it to restore full, seamless functionality to your vehicle just as the factory intended.
Important Post-Installation Information
While our programming handles the majority of the setup, some vehicles may require one or more of the following procedures to be performed with a professional scan tool after the BCM is installed:
- Airbag System Sync: If the airbag warning light is on after installation, the ‘Setup SDM Primary Key in BCM’ procedure is necessary to sync the new BCM with the airbag module.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be required to ensure proper brake light and traction control operation.
Disclaimer: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as it is essential for programming the module correctly.
Is this a difficult part to install?
For someone with moderate DIY mechanical experience, the physical installation is typically straightforward. The BCM is usually located under the dashboard. The main challenge with BCM replacement is programming, which we handle for you. However, as noted, some additional system relearns may be required with a professional scan tool.
Will this fix my specific electrical problem?
This Programmed 15819552 Body Control Module is a direct solution for failures within the BCM itself. While the symptoms listed are very common for BCM failure, we always recommend a proper diagnosis by a qualified mechanic to confirm the BCM is the source of the issue before ordering.
What if I see an airbag light after installation?
This is a normal possibility. The new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag system (SDM). A technician with a high-level diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Do I need to send my old part back?
No. This product comes with absolutely no core charge. You are free to keep or dispose of your old module as you see fit.
