Restore Peak Electrical Performance to Your GM Vehicle
Are you battling frustrating and unpredictable electrical issues in your vehicle? Flickering lights, malfunctioning power windows, a security system that acts on its own, or even a no-start condition can all point to a failing Body Control Module (BCM). For a high-duty vehicle like the 2011-2013 Chevrolet Caprice, reliability isn’t a luxuryโit’s a necessity. This Programmed 15819552 Body Control Module is the definitive, professional-grade solution to restore order and get your vehicle back in service with confidence.

Expert Insight: The BCM as Your Vehicle’s Central Command
Think of the Body Control Module as the central nervous system for your vehicle’s comfort and convenience features. It doesn’t manage the engine, but it orchestrates nearly everything elseโfrom the chime that reminds you to buckle up to the complex logic that controls your power locks and anti-theft system. In modern GM vehicles, the BCM is security-linked to other components. That’s why a generic, non-programmed module simply won’t work. Our VIN-programming service isn’t just a convenience; it’s a critical step that makes this a viable, effective repair.
Important Post-Installation Information
While this Programmed 15819552 Body Control Module is designed to simplify installation, certain vehicle systems may require a recalibration procedure after the new BCM is installed. These procedures require a professional bi-directional scan tool.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary to sync the systems.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be required to ensure proper brake light and traction control operation.
Please consult a factory service manual or a qualified automotive technician for vehicle-specific instructions.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that manages and controls a wide range of your vehicle’s electronic body accessories. This includes power windows, power mirrors, power door locks, the anti-theft system, interior and exterior lighting, and instrument panel warnings.
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as the programming is a critical part of the service.
Is this a simple plug-and-play installation?
Our VIN programming handles the most complex part of the setup. However, as noted above, some vehicles may require additional relearn procedures for systems like the airbags or brake pedal sensor using a professional scan tool. This is standard for this type of repair.
Will this fix my specific electrical problem?
This Programmed 15819552 Body Control Module is the direct solution for a failed BCM. While it resolves the many symptoms listed, we always recommend a proper diagnosis by a qualified technician to confirm the BCM is the root cause of your issue before ordering.
What happens if I install a BCM without programming?
An unprogrammed BCM will not function correctly. It can lead to a no-start condition, incorrect feature operation, and persistent error codes because it cannot communicate with the other modules in your vehicle. Our pre-programming service solves this problem for you.
Does this fit models other than the Caprice?
Yes. This BCM is compatible with a very wide range of GM vehicles, including the Impala, Acadia, various Express/Savana vans, Tahoe, Yukon, CTS, and more. Please check the detailed fitment list on this page to confirm it matches your specific year, make, and model.
