Restore Your Truck’s Electrical System with a VIN-Programmed BCM
Are you battling frustrating electrical gremlins in your GM truck or van? Flickering lights, malfunctioning power windows, a persistent security light, or a vehicle that refuses to start can often be traced back to a single component: the Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics. When it fails, it can cause a wide range of confusing and intermittent issues. This replacement BCM is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a straightforward installation.
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 or anti-theft light stays on, preventing the engine from starting.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Dashboard warning lights appearing without cause.
- ✔ Communication errors with diagnostic scan tools.

Important Post-Installation Information
While this module is programmed for your VIN, certain vehicle systems may require a relearn or synchronization procedure after installation. This is a normal part of the repair process. Specifically, be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure correct brake light operation and traction control functionality.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
What is a BCM and what does it control?
The Body Control Module (BCM) is a computer in your vehicle responsible for managing a wide variety of electronic accessories, such as power windows, locks, lights, the security system, and the horn. It’s the brain behind your vehicle’s comfort and convenience features.
How does the VIN programming service work?
After you place your order, you provide us with your 17-digit Vehicle Identification Number (VIN). Our technicians use this VIN to load the exact software and calibration files from GM for your specific vehicle onto the BCM before we ship it to you.
Is this part truly plug-and-play?
For most functions, yes. Because it’s programmed to your VIN, it will control the main features out of the box. However, as noted, some safety systems like the airbag (SRS) may require a simple synchronization procedure with a scan tool after installation.
What if my airbag light comes on after I install this BCM?
This is a known possibility. It means the new BCM needs to be electronically introduced to the vehicle’s airbag module (SDM). A qualified mechanic with a bidirectional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
