Expert Insight: The Importance of VIN Programming
Many people buy a used BCM online, only to find it doesn’t work. Why? Because a BCM is not a one-size-fits-all part. It’s programmed with the specific options of the vehicle it came from—like power seats, sunroof, or specific lighting packages. Installing an un-programmed or incorrectly programmed module can lead to features not working or even prevent the vehicle from starting. Our VIN-programming service is not just a convenience; it’s the crucial step that makes this a true, reliable repair. We ensure the brain of your van’s electronics matches its body perfectly.
Frequently Asked Questions
Do I need to have a dealer program this BCM after I receive it?
No. The main benefit of our service is that we program the Body Control Module to your vehicle’s specific VIN before we ship it. This makes the unit ready for installation right out of the box, saving you a trip to the dealership and additional programming costs.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a note to your order or reply to your order confirmation email. We cannot ship your part until we have this information.
What if my airbag light turns on after installation?
In some cases, the new BCM needs to be synced with the vehicle’s airbag system (SDM). If the airbag light is on, a procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed with a professional-grade scan tool. This is a common final step for this type of repair.
Is this a direct fit for my 2010 Express 2500?
Yes, this Programmed 2008-2012 Express 2500 BCM 20839063 is a guaranteed fit. It is also compatible with a very wide range of other GM trucks, vans, and SUVs from that era. To be certain, please match your original part number to the extensive list provided in the product details.
My original part number is different. Will this still work?
Most likely, yes. GM uses many different part numbers for the same component over the years. We have provided a comprehensive list of interchangeable part numbers that this module replaces. As long as your original number is on that list, this part will function correctly in your vehicle.
