Restore Your Vehicle’s Electrical System with a VIN-Programmed BCM
Are you battling frustrating electrical issues in your Chevrolet Express Van, GMC Savana, or other compatible GM vehicle? Flickering lights, malfunctioning power windows, a dead battery for no reason, or a security system that won’t cooperate 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 fails, it can create a cascade of confusing and unpredictable problems. Don’t let a faulty module keep you off the road. This direct-fit BCM, part number 22915542, is the definitive solution to restore full functionality and peace of mind.
Unlike a generic part from a salvage yard, this BCM arrives at your door fully programmed to your vehicle’s specific 17-digit VIN. We load it with the latest software updates directly from GM, ensuring optimal performance and compatibility with all your vehicle’s existing systems. This critical programming step saves you hundreds of dollars and the immense hassle of towing your vehicle to a dealership for expensive calibration. It’s a true plug-and-play solution designed for both professional technicians and savvy DIYers.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, and mirrors.
- ✔ Erratic or false warnings on the instrument cluster (e.g., ‘Service Theft System’).
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ Unexplained parasitic battery drain leading to a dead battery.
- ✔ Remote keyless entry (fob) not working correctly.
- ✔ Horn honking randomly or not working when pressed.
- ✔ Complete no-start condition where the engine cranks but won’t fire due to security system faults.
Installation and Required Procedures for Your Programmed Express 2500 BCM
Physical installation is straightforward for anyone with basic mechanical skills. After disconnecting the battery, the BCM can be unbolted and its electrical connectors removed. Simply swap in the new module and reconnect everything. However, due to the complexity of modern vehicle systems, some additional electronic steps, known as relearn procedures, may be necessary after the new module is installed.
Post-Installation Requirements:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM) and must be performed with a professional-grade scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure the brake lights and traction control systems function as intended.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What information do you need to program the BCM?
After you place your order, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This allows us to flash the module with the correct software and vehicle-specific options for a seamless installation.
Is this a simple plug-and-play installation?
Yes, for the most part. Because it comes pre-programmed, it eliminates the most difficult step. However, as noted in the description, some vehicles may require an airbag system sync or brake pedal position relearn procedure using a professional scan tool after the physical installation is complete.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module, which can be helpful for diagnostic comparison if needed.
How can I be sure the BCM is the cause of my problems?
The symptoms listed are very strong indicators of BCM failure. However, complex electrical systems can have multiple failure points. We always recommend having a qualified technician perform a full vehicle diagnostic scan to confirm the BCM is the faulty component before ordering.
Will this BCM have the latest software from GM?
Absolutely. We program every module with the newest software version available from GM for your specific VIN. This ensures you benefit from any fixes or improvements GM has released since your vehicle was manufactured.
