Is Your Truck’s 4WD System Unreliable?
Is the dreaded ‘Service 4WD’ light glaring from your dashboard? Are you finding it impossible to shift between 2WD and 4WD, leaving your capable truck stuck when you need it most? A faulty Transfer Case Control Module (TCCM) is the most common cause of these issues, effectively sidelining your vehicle’s all-terrain and foul-weather capabilities. Take back control with this direct-fit, professionally programmed GM Transfer Case Control Module 24239190, the definitive solution to restore your truck’s performance and your confidence.

If you’re experiencing any of the following, a failing TCCM is the likely culprit:
- “Service 4WD” or similar warning message on the instrument cluster.
- Inability to switch between 2WD, 4HI, and 4LO.

Frequently Asked Questions
How does the programming process work?
After you complete your purchase, you will need to provide us with your 17-digit VIN. Our technicians use this number to download the latest, most specific software calibration from GM for your exact vehicle configuration. We then flash this software onto the module before it is shipped to you.
Is this a plug-and-play part?
Yes. Because we pre-program the module to your VIN, it is a true plug-and-play installation. Simply disconnect the battery, swap the old module with the new one, and reconnect the battery. No further programming or dealer visits are required.
What happens if I don’t provide my VIN?
We cannot ship your order without a VIN. The programming is essential for the module to function correctly in your vehicle. We will hold your order and contact you to obtain the VIN to ensure you receive a fully functional part.
Will this fix the “Service 4WD” light on my dash?
In the vast majority of cases where the TCCM is the diagnosed point of failure, this part will resolve the issue and turn off the warning light. It’s always best to confirm the diagnosis with a scanner that can read transfer case codes (C-codes and U-codes) to be certain the module is the root cause.
