Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We program the module to your vehicle’s VIN before it ships. This allows for a simple plug-and-play installation without the need for any additional, expensive dealership programming.
Is installation difficult? Can I do it myself?
For most DIYers with basic tools, installation is straightforward. The BCM is typically located under the steering column. The process usually involves disconnecting the battery, removing a few trim panels, and swapping the modules. It can often be completed in under 30 minutes.
What if my airbag light is on after installation?
In some cases, the new BCM may need to be synced with the airbag system (SDM). This is a simple procedure called “Setup SDM Primary Key in BCM” that can be performed by any professional shop with a compatible high-end scan tool. This is only necessary if the airbag light appears after the BCM is installed.
Is there a core charge for my old part?
No, there is no core charge. You can keep or dispose of your old module without any hassle or need to return it.
Will this fix a specific trouble code like B1001?
Yes, this 2003-2007 Silverado 3500 Body Control Module is the correct component to resolve many body-related DTCs, including the common B1001 code which often points directly to an internal BCM failure.
