Frequently Asked Questions
How does the VIN programming process work?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). Our technicians use this number to load the exact, vehicle-specific software and calibrations from GM onto the module before we ship it to you.
Will I need to perform any procedures after installation?
In some cases, yes. Depending on your specific vehicle, a ‘Brake Pedal Position Relearn’ may be needed. Additionally, if your airbag warning light is on after installation, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems. These are standard GM procedures for this type of repair.
Is this a new or used part?
This is a quality, inspected, and tested recycled OEM part that has been programmed with the latest software for your vehicle, offering original equipment performance and reliability.
What if my original part number is slightly different but my vehicle is listed?
This module replaces a long list of interchangeable part numbers. As long as your vehicle model and year are listed in the compatibility chart, this programmed module will function correctly as a replacement for any of the part numbers shown.
Where is the BCM located on my GMC Acadia?
On the 2007-2012 GMC Acadia, the Body Control Module is typically located on the left-hand (driver’s side) of the dashboard, often behind the lower dash panel near the steering column.
