An Expert’s Insight: Many technicians will immediately suspect the transfer case encoder motor or the dash switch when 4WD issues pop up. While those components can fail, we see countless cases where the TCCM is the true root cause. It’s the brain of the system. A module with corrupted software or failed internal circuits can send faulty signals, making other good parts seem bad. By starting your diagnosis with a correctly programmed GM Transfer Case Control Module 24241970, you’re not just replacing a part; you’re ensuring the entire 4×4 system has a solid, reliable foundation to operate from, saving you time and money on misdiagnoses.
Frequently Asked Questions
Do I need to get this programmed by a dealer?
No. The main benefit of our service is that we program the module to your vehicle’s VIN before it ships. This makes the installation a true plug-and-play process, saving you the time and expense of a dealership visit.
Where is the TCCM located on my truck?
On most compatible GM trucks and SUVs, the Transfer Case Control Module is located on the driver’s side of the dashboard, up and to the left of the steering column. It’s typically a black box with a few electrical connectors.
Is this a simple plug-and-play installation?
Yes. Once you locate the old module, the process involves disconnecting the battery, unplugging the electrical connectors from the old TCCM, removing it, and installing the new one in its place. After reconnecting the battery, the system will be ready to go.
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit VIN. We cannot ship your order until we receive this information, as it is essential for the programming process. Please double-check it for accuracy.

If the TCCM is the cause of the fault, then yes, this part will resolve the issue and allow the warning light to be cleared. The GM Transfer Case Control Module 24241970 is the most common failure point for this specific warning.
