Restore Your Vehicle’s Electrical System with a Plug-and-Play BCM
Are you battling bizarre and frustrating electrical issues in your Chevrolet Impala or other compatible GM vehicle? From flickering lights and malfunctioning power windows to a haywire security system, these problems often trace back to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central nervous system for your car’s body electronics, and when it starts to go, it can create a cascade of seemingly unrelated problems. This isn’t just a replacement part; it’s a complete, pre-programmed solution designed to restore your vehicle’s functionality and your peace of mind.
We take the guesswork and dealership hassle out of the equation. Unlike a generic module from a salvage yard, this BCM is professionally flashed with the latest GM software updates and programmed specifically to your vehicle’s VIN before it ships. This ensures that all the features and options your car came with from the factory will work correctly right out of the box. Simply provide us with your VIN after purchase, and we’ll handle the complex programming, saving you time, money, and the need for expensive dealer-specific tools.
We recently had a 2011 Impala in the shop that was driving its owner crazy. The windshield wipers would randomly activate, the radio would shut off, and the key fob worked only half the time. There were no engine codes, just a host of intermittent communication faults. After ruling out wiring issues, we zeroed in on the BCM. We installed a VIN-programmed module just like this one, and it was like flipping a switch. Every single electrical gremlin vanished instantly. It’s a powerful reminder of how critical this single component is to the vehicle’s overall operation.
Is Your Vehicle Showing These Common BCM Failure Symptoms?
- ✔️ Intermittent or non-working power windows, door locks, or mirrors.
- ✔️ Erratic interior lights, headlights, or taillights that stay on or won’t turn on.
- ✔️ Malfunctioning keyless entry remote or anti-theft system.
- ✔️ False warning lights on the instrument cluster, such as the airbag or security light.
- ✔️ Windshield wipers or washers operating unpredictably.
- ✔️ Climate control or radio systems behaving erratically.
- ✔️ Communication errors when scanning with a diagnostic tool.
The Solution: A VIN-Programmed 2006-2013 Impala BCM
Replacing your BCM is the definitive fix for these issues. Our process ensures a seamless installation. By programming the module to your specific VIN, we ensure it communicates perfectly with your vehicle’s other computers, like the Engine Control Module (ECM) and Transmission Control Module (TCM). This direct-fit module, part number 20815898, is a reliable replacement for a wide range of original equipment part numbers, ensuring broad compatibility across many GM models including the Impala, Equinox, Acadia, various Express/Savana vans, and more. Check the detailed fitment list to confirm for your vehicle.
Installation and Required Procedures
Physically installing the BCM is generally straightforward, typically located under the driver’s side dash. However, after installation, some vehicles may require additional synchronization procedures. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct operation of brake lights and the traction control system.
Always consult a factory service manual or a qualified 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 your vehicle’s non-engine-related electronic features. This includes power windows, locks, lights, wipers, the security system, climate controls, and more. It acts as a hub, receiving input from switches and sensors and sending commands to the appropriate components.
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 process.
Is this BCM difficult to install myself?
For someone with basic automotive repair experience, the physical replacement is typically manageable. The BCM is usually located under the dashboard and involves disconnecting the battery and swapping electrical connectors. The main challenge can be the post-installation procedures, like the airbag sync, which may require a high-level diagnostic tool not owned by most DIY mechanics.
What happens if the airbag light comes on after I install it?
This is a common occurrence and does not mean the BCM is faulty. The new module needs to be electronically ‘introduced’ to the vehicle’s airbag computer (SDM). A qualified shop will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a compatible scan tool to resolve this.
Why is a pre-programmed module better than one from a junkyard?
A BCM from a junkyard is programmed to the VIN and specific options of the vehicle it came from. Installing it in your car will lead to compatibility issues, features not working, and potential security system lockouts. Our service provides a module that is a clean slate, programmed specifically for your vehicle’s exact configuration.
