Is that nagging “Service 4WD” light on your dash causing you headaches? Are you struggling with a four-wheel-drive system that won’t engage, or a selector switch that’s completely dead? You rely on your truck to perform in tough conditions, and a faulty Transfer Case Control Module (TCCM) can leave you stuck. This module is the electronic brain of your 4×4 system, and when it fails, it takes your truck’s all-terrain confidence with it.

Expert Insight: Why VIN Programming is Non-Negotiable
As a technician, I’ve seen countless people buy a used TCCM from a salvage yard only to find it doesn’t work. Why? Because these modules are not one-size-fits-all. A module from a Sierra with a specific transfer case option (like NQH) won’t work in a Suburban with a different one. The TCCM must be programmed to match the specific RPO codes (Regular Production Options) of your truck. By providing your VIN, you allow us to load the exact software configuration your vehicle left the factory with, guaranteeing a seamless and successful repair the first time.
Frequently Asked Questions
How does the VIN programming process work?
It’s simple. After you complete your purchase, you will provide us with your vehicle’s 17-digit VIN. We use professional-grade equipment and official GM software to flash the module with the correct calibration file for your specific truck or SUV. We then ship the fully programmed module to you.
Is this a difficult part to install myself?
For most DIYers, this is a very manageable job. The TCCM is typically located under the driver’s side of the dashboard, to the left of the steering column. It’s held in by a few bolts or clips and has electrical connectors. No special tools are required, and since our module is pre-programmed, there’s no software setup needed on your end. It’s a true plug-and-play part.
What does the Transfer Case Control Module (TCCM) actually do?
The TCCM acts as the central computer for your four-wheel-drive system. It receives input from the 4WD selector switch on your dash and then sends commands to the transfer case encoder motor to physically shift the transfer case between 2WD, 4WD High, and 4WD Low. A faulty module breaks this chain of command.
Will this Programmed 24249095 TCCM fix my “Service 4WD” light?
In the vast majority of cases where the symptoms match those listed above (no 4WD engagement, dead switch lights, etc.), a faulty TCCM is the root cause. Replacing it with this correctly programmed unit is the definitive fix and will clear the warning message after installation.
How do I know if this part is compatible with my vehicle?
Please review the detailed fitment list provided in the description. This module fits a wide range of GM trucks and SUVs from approximately 2007 to 2014, including the Silverado, Sierra, Tahoe, Suburban, and Yukon. Providing your VIN for programming is the final step that guarantees it will work perfectly for your specific vehicle.
