Restore Control Over Your Vehicle’s Electronics
Are you battling bizarre electrical gremlins in your GM vehicle? Flickering lights, malfunctioning power windows or locks, a security system that acts up, or even a car that refuses to start can all point to a single culprit: a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s comfort and convenience features. When it fails, it can cause a cascade of frustrating and seemingly unrelated problems. This isn’t just an inconvenience; it can compromise your vehicle’s security and functionality.
From the Diagnostic Bay
We had a 2008 Chevy Impala come in that was driving the owner crazy. The radio would turn on and off by itself, the driver’s side power window worked intermittently, and the remote key fob was useless. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic tool, we saw multiple communication errors all pointing back to the BCM. Instead of a dozen small problems, it was one central failure. By installing a VIN-programmed BCM like this one, we resolved all the issues in a single repair, saving the customer from a costly and confusing diagnostic journey at the dealership.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The security system or alarm malfunctioning or preventing the car from starting.
- ✔ The radio or infotainment system behaving erratically.
- ✔ Inconsistent or non-working dashboard warning lights.
- ✔ Problems with the heating and A/C controls.
- ✔ Complete no-start condition where the starter doesn’t even engage.
The Direct-Fit Solution: A Programmed GM Body Control Module
Don’t let a faulty module keep your car off the road. This Body Control Module is the definitive solution to restore your vehicle’s electronic systems to perfect working order. The most significant advantage we offer is our complimentary VIN programming service. When you purchase from us, you simply provide your vehicle’s VIN, and our technicians will flash the module with the latest, most stable software directly from GM. This ensures that the BCM is perfectly matched to your vehicle’s specific options and configuration, eliminating the need for an expensive trip to the dealership for programming.
This module is a direct replacement for a wide range of original part numbers, including 15828601, 25892622, 20815898, and many more. By installing this unit, you are getting a reliable, fully updated component that is ready for installation right out of the box.
Installation and Post-Install Considerations
While this module is designed for a straightforward swap, some vehicles may require additional steps after installation to ensure all systems communicate correctly. These are known as ‘relearn’ or ‘synchronization’ procedures.
- Airbag System Sync: If the airbag warning light is illuminated 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: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration may be necessary on certain models.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We handle the programming for you before we ship the part. Simply provide your vehicle’s VIN during or after checkout, and we will flash the module with the latest GM software for your specific vehicle.
What is a Body Control Module?
The Body Control Module, or BCM, is a computer in your vehicle responsible for managing a wide range of non-engine related functions, such as power windows, locks, lights, security system, and climate controls.
Is this a plug-and-play part?
Because we pre-program the module to your VIN, it is designed to be as close to plug-and-play as possible. However, as noted, some vehicles may require a simple ‘relearn’ or ‘sync’ procedure for the airbag or brake systems, which may require a professional scan tool.
What happens if my airbag light is on after installation?
This is a common occurrence. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A qualified technician with a high-level scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
How do I find my correct part number?
The best way is to look at the sticker on your original BCM. However, this module replaces many different part numbers. As long as your vehicle is on our compatibility list, providing us with your VIN is the most reliable way to ensure you get the correct, programmed part.
Is there a core charge for this part?
No, there is no core charge. You can keep your old module without needing to send it back to us.
