Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. This module is delivered to you pre-programmed using your vehicle’s VIN. This allows for a direct, plug-and-play installation without any need for additional dealer programming or specialized tools.
What tools are needed for installation?
Installation is straightforward and typically requires only basic hand tools, such as a socket set and a trim removal tool to access the module, which is located under the driver’s side dashboard near the steering column.
My airbag light is on. Will this fix it?
This BCM will often resolve the underlying electronic fault causing the airbag light, especially for codes like B1001. However, in some cases, a post-installation procedure called “Setup SDM Primary Key in BCM” may be required using a professional-grade scan tool to sync the new BCM with the airbag system and clear the light.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old module, saving you the time and hassle of shipping it back.
How do I know if my BCM is the problem?
Common signs of a failing BCM include erratic or non-working power windows, door locks, and interior/exterior lights; HVAC controls that don’t respond; security system faults; and various warning lights on the dash. If you’re experiencing multiple, seemingly unrelated electrical issues, the BCM is a primary suspect.
Will this programmed 2007-2011 Sierra 3500 BCM fit other GM trucks?
Yes, this module is compatible with a wide range of 2007-2013 GM trucks and SUVs, including the Silverado, Tahoe, Suburban, Yukon, and Escalade. Please refer to the detailed compatibility list on this page to confirm it fits your specific vehicle.
