Expert Insight: Why VIN Programming is Non-Negotiable
As a technician, I’ve seen countless drivers buy a used TCCM from a salvage yard only to find it doesn’t work.

Our VIN programming process ensures the programmed 2007-2014 Yukon XL 1500 TCCM we send you is a perfect electronic match, saving you from a frustrating and time-consuming repair process.

Frequently Asked Questions
How does the VIN programming process work?
It’s simple. After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). Our technicians will use your VIN to flash the module with the correct GM software and vehicle-specific calibration before we ship it to you.
Is this part truly plug-and-play?
Yes. Because we program the module to your specific VIN before shipment, it is ready to be installed without any further programming or calibration required. Simply disconnect the old module and connect this new one.
What happens if I forget to provide my VIN?
We cannot ship your order without the VIN. The programming is essential for the module to function in your vehicle. We will contact you to request the VIN, but providing it at checkout will ensure the fastest possible processing and shipping.
Will this fix the ‘Service 4WD’ light on my dashboard?
In the vast majority of cases where the symptoms match those listed above, a faulty TCCM is the root cause. Replacing it with this pre-programmed unit is the correct procedure to resolve the issue and extinguish the warning light.
Where is the TCCM located on my 2007-2014 Yukon XL?
On this generation of GM trucks and SUVs, the Transfer Case Control Module is typically located behind the lower dash panel on the driver’s side, to the left of the steering column. It is a small black box with a few electrical connectors.
