Restore Your Vehicle’s Electrical Functions with a Pre-Programmed BCM
Are you experiencing bizarre electrical issues in your Chevrolet Impala, GMC Acadia, or Cadillac CTS? Flickering lights, malfunctioning power windows, or a security system that has a mind of its own are common signs of a failing Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and difficult-to-diagnose problems. This replacement BCM, part number 22915542, is the definitive solution to restore your vehicle’s stability and functionality.
Unlike a standard replacement part from a dealership or local auto parts store, this module arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We handle the complex flashing process for you, loading the latest stable software updates from GM. This means you can avoid costly dealership programming fees and lengthy service appointments. Simply provide us with your VIN upon purchase, and our technicians will ensure the module is a perfect match for your vehicle’s factory options and configuration.
Is Your Body Control Module Failing?
A failing BCM doesn’t always result in a complete vehicle shutdown. More often, it presents as a collection of strange, intermittent electrical gremlins that can be maddening to pinpoint. If you’re noticing any of the following symptoms, a faulty BCM is the likely culprit.
- ✔ Erratic Lighting: Headlights, taillights, or interior dome lights flickering, staying on, or not working at all.
- ✔ Power Lock & Window Issues: Doors not locking/unlocking with the fob or switch, or windows that won’t go up or down consistently.
- ✔ Security System Faults: The factory alarm going off for no reason or the vehicle refusing to start due to a security immobilizer fault.
- ✔ Phantom Warning Lights: Dashboard lights for various systems (like ABS or airbags) illuminating intermittently without a true fault in those systems.
- ✔ Parasitic Battery Drain: A dead battery after the vehicle sits for a short period, caused by the BCM failing to let other modules go to ‘sleep’.
- ✔ HVAC Control Problems: Blower motor or temperature controls not responding correctly.
The Superior Solution: A Programmed 2013-2016 Impala BCM
This isn’t just a replacement part; it’s a comprehensive repair solution. By choosing our pre-programmed 2013-2016 Impala BCM, you are bypassing the most complicated part of the repair. Our process ensures a seamless integration with your vehicle’s existing electronic systems. We use your VIN to access the exact factory build data, configuring the BCM to control all the options your vehicle was built with—from the type of headlights to the specific radio installed. This attention to detail prevents compatibility issues that can arise from using a generic, non-programmed module.
Installation and Post-Install Procedures
Installation is straightforward for an experienced DIYer or any professional technician. The BCM is typically located on the left-hand side of the dash. While our programming handles the majority of the setup, some GM vehicles require one or two final synchronization steps after the new module is installed. These are known as ‘relearn’ procedures and are necessary to ensure all vehicle systems communicate correctly.
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag control module (SDM) and requires a professional-grade diagnostic tool.
- Brake Pedal Position Relearn: Some models may require a recalibration of the brake pedal position sensor. This is crucial for proper brake light operation and the function of the traction control and stability control systems.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls many of its non-engine related electronic functions. This includes power windows, power locks, interior and exterior lighting, the security system, wipers, and more.
Is this BCM truly plug-and-play?
It is ‘plug-and-program-and-play’. We do the main programming to your VIN before shipping. However, as with any BCM replacement on these GM vehicles, you may need to perform a simple key relearn or have a technician perform a post-install procedure like an airbag sync or brake pedal position relearn to fully integrate the module.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically add it as a note during checkout or send it to us in a message referencing your order number. We cannot ship the part until we receive the VIN.
Do I need to return my old BCM?
No. This product comes with no core charge. You can keep your original module, which can be helpful for reference or if you ever need to revert to the original part for diagnostic purposes.
What tools are needed for the post-installation procedures?
While the physical installation requires basic hand tools, procedures like the ‘Setup SDM Primary Key’ or brake pedal relearn require a bi-directional, professional-grade diagnostic scan tool. Most basic OBD-II code readers cannot perform these functions. We recommend professional installation if you do not have access to such a tool.
