Restore Your Vehicle’s Electrical System
Are you battling frustrating electrical gremlins in your GM vehicle? Flickering lights, malfunctioning power windows, a temperamental security system, or strange warning lights on your dash are all 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 starts to fail, it can cause a wide range of confusing and intermittent issues. This replacement GM Body Control Module is the definitive solution to restore full functionality and peace of mind.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, locks, or mirrors operating intermittently or not at all.
- ✔ Vehicle security system faults or alarm sounding unexpectedly.
- ✔ Key fob not being recognized or functioning properly.
- ✔ Warning lights on the dashboard, such as the airbag or brake light.
- ✔ Communication errors with other vehicle modules (U-codes).
- ✔ Horn not working or sounding off on its own.
Why Choose a Pre-Programmed GM Body Control Module?
The biggest hurdle in replacing a BCM is the need for vehicle-specific programming. Without it, the module won’t communicate with your car’s other systems. Our service eliminates this step. We take your vehicle’s VIN and flash this module with the latest GM-certified software and your car’s exact configuration. This makes the installation process as simple as possible, saving you from expensive dealership programming fees and towing costs. This unit is a direct replacement for a wide range of part numbers, including 15276271, 22860591, 25892622, and many more, ensuring compatibility across numerous GM models.
Installation and Required Procedures
While this module is designed to be plug-and-play, some vehicles may require simple post-installation relearn procedures. These are not full programming sessions but rather quick syncs that can often be done with a capable scan tool. Key procedures may include:
- Airbag System Sync: If your airbag light illuminates after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the new BCM with the airbag system. This is a security measure and requires a professional-grade diagnostic tool.
- Brake Pedal Position Relearn: To ensure your brake lights and traction control work correctly, a brake pedal position sensor relearn might be necessary.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that controls many of your vehicle’s non-engine related functions, such as power windows, locks, lights, wipers, security system, and key fob operation.
Do I need to send my VIN after ordering?
Yes. We cannot ship your module until we receive your vehicle’s 17-digit VIN. This is essential for us to program the BCM with the correct software and options for your specific car, truck, or SUV.
Is this part truly plug-and-play?
For most vehicles, yes. Because we pre-program it to your VIN, it eliminates the need for a dealership visit. However, as noted, some models may require minor relearn procedures for systems like the airbags or brake sensor, which can be performed by most automotive shops.
What happens if my airbag light is on after I install this?
This is a normal security precaution in many GM vehicles. The airbag module (SDM) needs to be electronically ‘introduced’ to the new BCM. This procedure, called ‘Setup SDM Primary Key in BCM’, must be done with a professional scan tool to turn off the light.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your original module.
