Restore Full Functionality to Your Vehicle’s Electronics
Is your GM vehicle suffering from strange and unpredictable electrical problems? Flickering lights, malfunctioning power windows or locks, a security system that acts up, or warning lights that won’t go away 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 fails, it can cause a wide range of frustrating issues. This replacement BCM is the definitive solution to restore your vehicle’s performance and reliability.
We take the guesswork and high cost out of the repair process. Unlike a standard replacement part that requires a trip to the dealership for expensive programming, this module arrives at your door pre-programmed to your vehicle’s specific VIN. We flash it with the latest, most stable software updates from GM, ensuring optimal performance and compatibility right out of the box. This is a direct-fit, plug-and-play solution designed to get you back on the road quickly and affordably.
Why Our Programmed GM Body Control Module is the Best Solution
Choosing our BCM means you are getting a part that is not only a perfect physical fit but also a perfect electronic match for your vehicle. By providing your VIN during checkout, you ensure that the module is configured for the exact options and features your vehicle was built with. This eliminates compatibility conflicts and the need for advanced scan tools for initial setup, saving you time and hundreds of dollars in labor costs.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Vehicle security system or keyless entry failing.
- ✔ Wipers or horn activating unexpectedly.
- ✔ False warnings on the instrument cluster (e.g., “Service Theft System”).
- ✔ Rapid battery drain while the vehicle is off.
- ✔ Communication issues with other vehicle modules.
Installation and Post-Install Notes
Physical installation is typically straightforward, involving disconnecting the battery and swapping the old module with the new one. However, depending on your specific model, some additional steps may be required after the part is installed. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper function of the brake lights and stability control systems.
This Programmed GM Body Control Module is a reliable and cost-effective way to solve your vehicle’s electrical woes. With no core charge and pre-loaded software, it’s the smartest choice for both DIYers and professional technicians.
Frequently Asked Questions
How do I know if my Body Control Module is failing?
Common signs include multiple, unrelated electrical issues like malfunctioning power locks and windows, erratic lights, security system faults, and false dashboard warnings. A diagnostic scan at a repair shop can confirm the failure.
What is VIN programming and why is it important?
VIN programming involves loading your vehicle’s specific Vehicle Identification Number and factory options into the BCM. This ensures all features (like keyless entry, power seats, specific lighting, etc.) work correctly without needing a trip to the dealer.
Do I need to take my car to the dealer after installing this?
In most cases, no. Our BCM is designed to be a plug-and-play solution. However, in some instances, a simple relearn procedure for the airbag or brake pedal position sensor may be required, which can be done by most independent shops.
Where is the BCM located on my vehicle?
The location varies by model. Common locations include under the driver’s or passenger’s side of the dashboard, behind the glove box, or in the center console area. Your service manual will show the exact location.
What happens if my airbag light comes on after installation?
This indicates the new BCM needs to be electronically synced with your vehicle’s airbag module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed by a technician with a capable diagnostic tool to resolve this.
Does this part have a core charge?
No, there is no core charge for this module. You can keep your old part.
