Restore Full Electronic Functionality to Your Vehicle
Is your Chevrolet Caprice or other GM vehicle acting possessed? Flickering lights, malfunctioning power windows, a security system that won’t cooperate, or random warning lights on the dash are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your car’s body electronics, and when it starts to fail, it can create a cascade of frustrating and seemingly unrelated electrical problems. This isn’t just an inconvenience; it can affect the safety and reliability of your vehicle. Don’t let a faulty module keep you guessing. This direct-fit replacement BCM is the definitive solution to restore order and get your car’s features working like new again.
From the Diagnostic Bay
We recently had a 2012 Caprice PPV in the shop with a textbook BCM failure. The officer reported that the interior dome lights would stay on intermittently, the power locks would cycle on their own, and the turn signals worked only when they wanted to. A scan tool showed multiple communication loss codes with various systems. After confirming power and grounds to the BCM were solid, we knew the module itself was the culprit. Swapping in a pre-programmed BCM like this one resolved all the issues in under an hour, saving the department significant downtime and the high cost of dealer diagnostics and programming.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, taillights, dome lights).
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Vehicle security system or keyless entry malfunctions.
- ✔ Horn sounding unexpectedly or not working when pressed.
- ✔ Wipers behaving erratically (e.g., won’t turn off).
- ✔ False warnings on the instrument cluster (e.g., ‘Door Ajar’ light).
- ✔ Communication issues with other vehicle modules, leading to various diagnostic trouble codes (DTCs).
Why Choose Our Pre-Programmed Caprice Body Control Module?
The biggest hurdle in replacing a modern BCM is the required programming. A new module from the dealership is a blank slate and will not function until it’s programmed with expensive, specialized equipment. We eliminate this step entirely. When you order from us, you provide your vehicle’s VIN, and our technicians will flash this module with the latest, stable software release from GM specifically for your car. This ensures all factory-installed options are recognized and function correctly right out of the box. It’s a true plug-and-play solution that saves you a costly trip to the dealership.
Installation and Post-Install Procedures
Installation is straightforward for anyone with basic mechanical skills. The BCM is typically located under the dashboard on the driver’s side. After disconnecting the battery, you simply unplug the electrical connectors from the old module, unbolt it, and install the new one in its place. While our programming handles the heavy lifting, some vehicles may require a simple relearn procedure after installation.
- Airbag System Sync: In some cases, the airbag light may illuminate after installation. This indicates a sync is needed between the new BCM and the airbag system’s SDM module. A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration might be necessary to ensure proper operation of brake lights and stability control systems.
Please note: Specific procedures can vary. We always recommend consulting a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship the module until we have this information to perform the programming service.
Is this a simple plug-and-play installation?
Yes, for most vehicles. We program the module to your VIN so it communicates with your car’s existing systems. However, as noted above, some vehicles may require additional relearn procedures for systems like the airbags or brake pedal sensor, which require a professional scan tool.
Will this BCM fix my specific problem?
This module will resolve issues directly caused by a faulty BCM. It is crucial to properly diagnose the problem before ordering. If your issue is due to a wiring short, a bad switch, or a different faulty module, replacing the BCM will not fix it.
What if my original part number is not on the list?
The provided list covers many compatible part numbers. If your number is not listed, please contact us with your VIN and original part number before ordering to confirm compatibility. We want to ensure you get the right part the first time.
