From the Diagnostic Bay
n
We had a 2004 GMC Jimmy come in that was driving the owner crazy. The interior dome lights would randomly turn on and stay on, even overnight, completely draining the battery. He’d already replaced the battery twice. After checking door jamb switches and wiring, we traced the fault to an internal short in the BCM. It was sending a constant ‘on’ signal to the lighting circuit. Installing a VIN-programmed BCM like this one solved the problem in under 30 minutes. The customer was thrilled to have a reliable truck again without the fear of a dead battery every morning.

- Airbag System Sync: If your airbag warning light illuminates after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag system and can be performed by any shop with a professional-grade diagnostic tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary for proper brake light and traction control operation.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and the instrument cluster.
Is this BCM difficult to install?
For most individuals with basic mechanical skills, the installation is simple. It involves locating the old module (usually in the dash), disconnecting the battery, swapping the electrical connectors to the new module, and mounting it. Since we program it to your VIN, no dealer visit for programming is required.
Do I need to send my old BCM back?
No, there is no core charge for this module. You can keep your original part.
What if my airbag light is on after installation?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A repair shop with a capable scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive your VIN.
Will this part fit my 2002 GMC Sierra 2500?
Yes, this BCM fits a wide variety of 2002-2005 GM trucks and vans. It is a compatible replacement for a 2002 Sierra 2500. Always match your original part number to the list provided to guarantee fitment.
