Are you battling frustrating electrical gremlins in your GM truck or SUV? Issues like flickering lights, malfunctioning power windows and locks, or a security system that acts on its own 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 starts to fail, it can cause a wide range of confusing and intermittent problems. This replacement BCM, part number 19208537, is the definitive solution to restore full functionality and reliability to your vehicle.
We take the guesswork and hassle out of the replacement process. Unlike a standard part from a dealership or parts store, this BCM arrives at your door pre-programmed to your vehicle’s specific Vehicle Identification Number (VIN). Simply provide us with your VIN after purchase, and our technicians will flash the module with the latest, most stable software updates from General Motors. This ensures seamless integration with your vehicle’s existing systems, saving you a costly trip to the dealership for programming.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security system or anti-theft light is always on, preventing the vehicle from starting.
- ✔ Inaccurate or dead gauges on the instrument cluster.
- ✔ The radio or climate control system behaves unpredictably.
- ✔ Diagnostic trouble codes related to communication loss with other modules (U-codes).
- ✔ Unexplained battery drain when the vehicle is turned off.

Important Post-Installation Information
While this module is designed for a straightforward installation, some vehicles may require additional steps to fully sync with the new BCM. Please be aware of the following potential 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: On some models, a brake pedal position sensor recalibration might be necessary to ensure the brake lights and traction control system function correctly.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What does a BCM do on my 2002 GM truck?
The Body Control Module (BCM) acts as the brain for your vehicle’s body electronics. It controls features like power windows, door locks, interior and exterior lighting, the security system, and the instrument cluster.
Do I need to program this BCM?

What is the ‘Airbag System Sync’ procedure?
This is a recalibration procedure that may be needed if your airbag light comes on after installation. It uses a professional diagnostic tool to establish communication between the new BCM and the airbag system’s computer (SDM), ensuring they work together correctly.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information.
