Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s body electronics. It manages non-engine-related functions like power windows, door locks, interior and exterior lighting, the security system, wipers, and the HVAC system.
Is this module difficult to install?
For most DIYers with basic tools, the installation is straightforward. The BCM is typically located under the driver’s side dashboard near the steering column and can often be replaced in under 15 minutes. No special tools are required for the physical swap.
Will this BCM need to be programmed by a dealer?
No. The main benefit of our service is that we pre-program the module to your vehicle’s VIN before shipping. This makes it a plug-and-play part, saving you the time and significant expense of a dealership visit for programming.
What happens if my airbag light is still on after installation?
In some cases, especially if DTC B1001 was present, a final sync procedure called “Setup SDM Primary Key in BCM” may be needed. This requires a professional-grade scan tool but is a simple function that syncs the new BCM with the airbag system. This is much simpler and faster than full programming.
How do I know if this part fits my vehicle?
Please check the comprehensive compatibility list on this page. This module fits a wide range of 2007-2013 GM trucks and SUVs like the Silverado, Sierra, Tahoe, Suburban, and Escalade. You can also match the part number 25844480 or any of the listed interchange numbers to your original part.
Is there a core charge for my old part?
No, there is no core charge. You are not required to send your old BCM back to us, which simplifies the repair process for you.
