Frequently Asked Questions
What does a Body Control Module do on a 2013 GMC Sierra?
The BCM acts as the central computer for your truck’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. When it fails, these systems can become unreliable.
Is this BCM difficult to install?
Installation is typically straightforward for someone with basic mechanical skills. The BCM is located under the driver’s side dashboard, near the steering column. The physical replacement often takes less than 15 minutes. No special programming is needed as we handle that before shipping.
Will I need to go to the dealership after installation?
No. Our VIN programming service makes this a plug-and-play part. It’s designed to work immediately upon installation, saving you the time and expense of a dealership visit for programming. The only exception is a potential airbag system sync, detailed below.
What if my airbag light is still on after installing the new BCM?
In some cases, if the original BCM failed and stored airbag codes (like B1001), you may need to perform a ‘Setup SDM Primary Key in BCM’ procedure. This requires a professional-grade scan tool and syncs the new BCM with the airbag system. This is a simple procedure for any qualified repair shop.
How do I ensure this is the correct part for my truck?
This module, GM part 25844480, fits a wide range of 2007-2013 GM trucks and SUVs. You can confirm fitment by matching your original part number to the extensive interchange list on this page. Providing your VIN at checkout is the best way to guarantee you receive a perfectly matched and programmed module.
Is there a core charge for this 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.
