Frequently Asked Questions
What does a BCM do on my 2013 Sierra 2500?
The Body Control Module (BCM) acts as the central computer for your truck’s non-engine related electronics. It manages functions like your interior and exterior lights, power windows, door locks, wipers, security system, and HVAC climate controls.
Is this BCM truly plug-and-play?
Yes. We program the module to your vehicle’s specific VIN before shipping. This means it will be ready for installation right out of the box, with no additional programming required from a dealership for standard operation.
What if my airbag light is still on after installation?
In some cases, particularly if you had an airbag-related code 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 your truck’s airbag system.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep or dispose of your old module at your convenience, simplifying the repair process.
What tools are required for installation?
Installation is typically very straightforward. The BCM is located under the driver’s side dash, and you will usually only need basic hand tools like a socket set or a screwdriver to remove the lower dash panel for access.
How can I be sure this is the correct part for my truck?
This module is a direct fit for the 2013 GMC Sierra 2500 and is interchangeable with many part numbers listed in the description.
