Expert Insight: The Power of VIN Programming
Why is VIN programming so critical? A BCM isn’t a one-size-fits-all part. It communicates with nearly every other module in your vehicle, from the engine computer to the airbag system. Our VIN programming service configures the module with the specific software and settings your truck left the factory with. This prevents compatibility issues, ensures all your vehicle’s options work correctly, and saves you from a mandatory, costly trip to the dealership for setup. It’s the key to a successful and stress-free repair.
Frequently Asked Questions
What does the 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 your interior and exterior lights, power windows and locks, wipers, security system, and HVAC controls.
Is this BCM truly plug-and-play?
Yes. By providing your vehicle’s VIN during checkout, we program the module specifically for your truck or SUV. This allows you to install it directly without needing any further programming from a dealership, saving you time and money.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your old module without any hassle or extra fees.
What if my airbag light is on after installation?
In some cases, the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). This is a security procedure called ‘Setup SDM Primary Key in BCM’ and requires a professional-grade scan tool to complete. It is only necessary if the airbag light remains on after the BCM is installed.
How do I know this will fit my vehicle?
This module fits a wide range of 2002-2007 GM trucks, vans, and SUVs, including the Silverado, Sierra, Tahoe, Suburban, and Escalade.

Our 2003-2007 Sierra 3500 BCM 15137395 is a guaranteed fit for specified models.
Where is the BCM located on my truck?
On most compatible trucks and SUVs like the Sierra and Silverado, the BCM is located under the driver’s side dashboard, near the steering column. On Savana and Express vans, it is typically found in the center dash area. Installation usually takes less than 15 minutes.
