Restore Your Vehicle’s Electrical Functions
Are you dealing with strange and frustrating electrical issues in your GM vehicle? Power windows acting up, interior lights failing, or a security system that won’t behave? These are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it malfunctions, it can cause a cascade of seemingly unrelated problems. This replacement GM Body Control Module is the definitive solution to restore your vehicle’s functionality and peace of mind.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ Malfunctioning security system or keyless entry remote.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Dashboard warning lights (like the airbag or security light) illuminating for no reason.
- ✔ Communication errors with diagnostic scan tools.
Why Choose Our Programmed GM Body Control Module?
Getting your vehicle back to normal shouldn’t require expensive dealership visits and complex procedures. We’ve simplified the process. When you order this BCM, you provide us with your vehicle’s VIN. Our technicians then flash the module with the latest, most stable software directly from GM, ensuring it is perfectly matched to your vehicle’s specific options and configuration. It arrives at your door ready for installation, eliminating the need for costly dealer programming. This is a direct-fit replacement for a wide range of original part numbers, including 15299986, 22860591, 25892622, and many more listed in the fitment guide.
Installation and Post-Install Steps
Physically installing the BCM is typically straightforward, involving disconnecting the battery and swapping the old module with the new one, usually located under the dashboard. While our VIN programming handles the most critical setup, some vehicles may require one or two final synchronization steps after installation:
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure brake lights and traction control systems function correctly.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.
Frequently Asked Questions
How does the VIN programming service work?
After you place your order, you will need to provide us with your 17-digit Vehicle Identification Number (VIN). Our technicians use this VIN to load the correct GM-certified software and calibrations onto the module before we ship it. This ensures it works correctly with your vehicle’s specific features.
Do I need to go to a dealer after installing this part?
No, our pre-programming service is designed to eliminate the need for a trip to the dealership for software flashing. In some cases, minor relearn procedures as described above may be required, which can be done by most independent repair shops.
My original part number is not 15299986. Will this still work?
Yes. This BCM is a direct, compatible replacement for all the part numbers listed in the product description. As long as your original part number is on our list, this module will fit and function correctly in your vehicle.
What tools are needed for the post-installation procedures?
The Airbag System Sync and Brake Pedal Position Relearn procedures require a high-level, bi-directional diagnostic scan tool, such as a GM Tech 2, MDI, or equivalent professional-grade scanner. Basic OBD-II code readers cannot perform these functions.
Is there a core charge for my old BCM?
No, there is no core charge. You can keep your original module without needing to send it back to us.
