An Expert’s Note on TCCM Replacement
As a technician with over two decades of experience, I’ve seen countless truck owners get frustrated by 4WD problems.

It’s not just a part; it’s a complete solution that saves you a massive headache and gets the job done right the first time.
Frequently Asked Questions
What exactly does the Transfer Case Control Module do?
The TCCM is the ‘brain’ of your vehicle’s four-wheel-drive system. It receives input from the driver (via the 4WD selector switch) and various sensors, then commands the transfer case motor to shift between 2WD, 4WD High, and 4WD Low.
Is any additional programming or a ‘relearn’ procedure needed after I install this?
No. Because we program the module to your specific VIN before shipping, it is a true plug-and-play part. Simply disconnect the battery, swap the old module with the new one, reconnect the battery, and you’re ready to go. No special tools or dealer visits are required.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive the VIN, as this information is essential for programming the module correctly for your specific vehicle.
Where is the TCCM located on my truck?
On most compatible GM trucks and SUVs from this era (2007-2014), the TCCM is located on the driver’s side of the dashboard, up and to the left of the steering column. It is typically a black box with several electrical connectors.
Will this fix my ‘Service 4WD’ light?
In the vast majority of cases where the TCCM has failed, this part will resolve the issue and turn off the ‘Service 4WD’ light. However, we always recommend properly diagnosing the problem or checking for trouble codes to ensure the module is the source of the fault, as other components like the encoder motor or selector switch can also cause similar symptoms.
By purchasing this programmed 24241970 transfer case control module, you’re not just buying a part—you’re buying a complete, hassle-free solution to get your truck’s essential 4WD system back in operation.
