Restore Full Electronic Functionality to Your GM Vehicle
Are you battling bizarre and frustrating electrical issues in your GM car, truck, or SUV? A failing Body Control Module (BCM) is often the culprit. The BCM acts as the central nervous system for your vehicle’s comfort and convenience features. When it malfunctions, it can cause a cascade of problems that seem unrelated, making diagnosis a nightmare. This replacement module is your direct, reliable solution to restore order and get your vehicle’s electronics working like new again.
This isn’t just a part in a box. We provide a crucial service by pre-programming this module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This means it arrives ready for installation, loaded with the latest GM software updates, saving you from a costly and time-consuming trip to the dealership for programming.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system or keyless entry malfunctioning.
- ✔ Wipers behaving unpredictably (turning on by themselves, not turning off).
- ✔ The radio or infotainment system acting up.
- ✔ Unexplained battery drain that leaves you stranded.
- ✔ False warning lights on the instrument cluster.
From the Diagnostic Bay
We had a 2008 Chevy Impala come in with a classic case of BCM failure. The customer complained that their turn signals would sometimes work, and other times they wouldn’t. The dome light would flicker, and the radio would randomly shut off. They had already replaced the battery, thinking it was a power supply issue. After a quick diagnostic scan, we traced all the faults back to the BCM. By installing a VIN-programmed module like this one, we resolved all the ghost-like electrical issues in under an hour, saving the customer from further diagnostic headaches and unnecessary parts replacement.
Why Our Programmed GM Body Control Module is the Smart Choice
Choosing the right replacement part is critical. Our Programmed GM Body Control Module is designed to be a seamless and effective solution. We handle the complex programming so you can focus on the installation. Simply provide your VIN during checkout, and our technicians will flash the module with the correct software for your vehicle’s specific options and features. This ensures compatibility and proper function right out of the box.
Installation and Required Procedures
While this module is designed for a straightforward installation, some vehicles may require additional steps to ensure all systems communicate correctly. After installation, you may need to perform a couple of relearn procedures:
- Airbag System Sync: If the airbag warning light illuminates after you install the new BCM, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This syncs the new BCM with the airbag system and requires a professional-grade scan tool.
- Brake Pedal Position Relearn: To ensure your brake lights and traction control system function correctly, a brake pedal position sensor recalibration may be required on certain models.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls many of the non-engine related electronic functions, such as power windows, locks, lights, wipers, security systems, and more.
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). We will use this to load the correct software for your vehicle’s exact configuration before shipping the part to you.
Is this a simple plug-and-play installation?
For many vehicles, it is. The module is pre-programmed to eliminate the need for dealer software flashing. However, as noted, some models may require additional ‘relearn’ procedures for the airbag or brake systems, which may require a professional scan tool.
What happens if my airbag light is on after installation?
This indicates that the BCM needs to be synchronized with the airbag’s Supplemental Deployment Module (SDM). A technician with a capable diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
