A Note From Our Technicians: A common oversight during BCM replacement is neglecting the main ground connections. A poor ground can mimic the symptoms of a failed module and can cause premature failure of a new part. When you install your new 2007-2011 Sierra 2500 Body Control Module, take an extra two minutes to locate, disconnect, and clean the main BCM ground point under the dash.

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 BCM difficult to install?
No, the physical installation is typically very simple. The BCM is usually located under the driver’s side dashboard near the steering column. The process involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors. Most people can complete the installation in under 30 minutes.
Will I need to take my truck to the dealership for programming?
Absolutely not. We program the module to your vehicle’s VIN before we ship it. This means it is ready for installation right out of the box, saving you the time and expense of a dealership visit.
What if my airbag light is still on after installation?
In some cases, particularly if DTC B1001 was present, a final sync procedure called ‘Setup SDM Primary Key in BCM’ is needed. 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.
Is there a core charge for this part?
No, there is no core charge. You can keep your old module without needing to send it back to us, simplifying the process for you.
How do I ensure this is the correct BCM for my vehicle?
