Are you battling frustrating electrical problems in your GM truck or van? Flickering lights, malfunctioning power windows and locks, or a security system that acts on its own are common signs of a failing Body Control Module (BCM). The BCM is the central command for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent issues. This replacement BCM, part number 19208537, is the direct-fit, reliable solution to restore your vehicle’s proper function.
This isn’t just a generic part off the shelf. We program each module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This critical step ensures compatibility with your truck’s options and loads the latest, most stable software updates from GM. This eliminates the need for an expensive trip to the dealership for programming, saving you time and money.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights)
- ✔ Power windows, door locks, or mirrors working intermittently or not at all
- ✔ Vehicle security system engaging randomly or preventing the engine from starting
- ✔ Horn honking unexpectedly
- ✔ Inaccurate or dead gauges on the instrument cluster
- ✔ “Service Vehicle Soon” or other warning messages appearing on the dash
Get Your Programmed 2002 Silverado Body Control Module
Ordering is simple. After you complete your purchase, just send us your vehicle’s 17-digit VIN. Our technicians will then flash the module, ensuring it’s a perfect match for your vehicle’s configuration. This process makes installation straightforward. In most cases, once the new module is installed, your vehicle’s functions will be immediately restored. Best of all, there is no core charge, so you can keep your original module.
Post-Installation Procedures
While this module is designed for a simple installation, some vehicles may require minor electronic handshakes after the new BCM is connected. These are not signs of a defective part but are standard procedures for vehicle security and safety systems.
- Airbag System Sync: If your airbag warning light is on after installation, a procedure called ‘Setup SDM Primary Key in BCM’ may be needed. This syncs the new BCM with the airbag system and requires a professional-grade scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure brake lights and traction control function correctly.
Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and more.
Is this BCM truly plug-and-play?
Because we program it to your VIN, it is as close to plug-and-play as possible. It will work out of the box for most vehicles. However, as noted, some models may require a simple relearn procedure for the airbag or brake systems, which is a standard vehicle security measure.
How do I provide my VIN after purchase?
After you place your order, you will receive instructions on how to reply with your 17-digit VIN. We cannot program and ship the module without it.
What happens if my airbag light is on after installation?
This is a normal security feature on some GM vehicles. It means the new BCM needs to be electronically introduced to the airbag’s computer (SDM). A repair shop with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to return my old BCM?
No. This product has no core charge. You can keep your original part.
