An Expert’s Note on BCM Replacement

This empowers you, the owner, to fix your own truck, saving hundreds of dollars and getting your workhorse back in service faster. It’s the most efficient way to solve these complex electrical issues.”
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, interior lights, the security system, and the instrument cluster. When it fails, these systems can become unreliable.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive it. This ensures the 2002 Silverado 2500 BCM is a perfect match for your vehicle’s options.
Will I need to do anything after installation?
In most cases, the module is ready to go. However, on some models, you may need a professional scan tool to perform a ‘Setup SDM Primary Key in BCM’ procedure if the airbag light comes on, or a ‘Brake Pedal Position Relearn’. These are simple sync procedures that a qualified technician can perform if necessary.
Is this a difficult part to install myself?
For someone with basic mechanical skills, the physical installation is straightforward. The BCM is typically located under the steering column or in the center dash. The main challenge is the programming, which we handle for you before shipping the part.
How do I know if this fits my vehicle?
This module fits a wide range of 2002-2005 GM trucks, vans, and SUVs. Please check the detailed fitment list on this page and confirm that your original part number (e.g., 15081796, 15063578, etc.) is listed. Providing your VIN guarantees we send the correctly programmed unit.
