Restore Your 4×4 System with a Reliable, Programmed TCCM
As a technician with over two decades of experience under the hood of GM trucks, I’ve seen countless owners frustrated by the dreaded “Service 4WD” light. Your 2007-2014 GMC Yukon XL 1500 is a capable machine, but when the Transfer Case Control Module (TCCM) fails, you’re left without the all-terrain confidence you depend on. The TCCM is the electronic brain of your four-wheel-drive system, responsible for interpreting your commands from the dash switch and engaging the transfer case motor. When it goes bad, you’re stuck.
The typical repair path involves a costly trip to the dealership for the part, followed by another appointment and fee for programming. We eliminate that hassle. This TCCM, part number 24243085, arrives at your door fully programmed with the latest GM software, specifically flashed to your vehicle’s VIN. This isn’t just a part; it’s a complete, ready-to-install solution that saves you time, money, and a trip to the dealer.
From the Diagnostic Bay
I remember a 2011 Sierra 2500 that came into my shop. The owner had already replaced the transfer case encoder motor himself after watching a video online, but the “Service 4WD” light remained on, and he still couldn’t switch modes. He was convinced the new motor was faulty. After connecting my scan tool, I saw communication codes (U-series) pointing to the TCCM. The module wasn’t sending the right signals. We installed one of our pre-programmed TCCMs, and within 15 minutes, the system was fully operational. It’s a classic case where a simple electronic failure can mimic a more complex mechanical one. Always check the brain before assuming the muscle is the problem.
Is Your Yukon Showing These Symptoms?
- ✔ “Service 4WD” or “Service Four Wheel Drive” message on the instrument cluster.

A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the Module: The TCCM is typically located on the driver’s side of the dashboard, behind the lower dash panel or near the steering column. You may need to remove a plastic trim panel for access.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old module. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old TCCM from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed TCCM in the same location. Secure it with the original hardware.
- ✔ Reconnect and Finalize: Plug the electrical connectors firmly into the new module. You will hear a click when they are seated correctly. Reinstall any trim panels you removed and reconnect the negative battery terminal.
- ✔ Test the System: Start the vehicle and test the 4WD selector switch to confirm proper operation between all modes. The “Service 4WD” light should be off.

Frequently Asked Questions
What is the process for programming?
It’s simple! After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We use your VIN to load the latest, most compatible GM software onto the module before we ship it to you.
Is any additional programming needed after installation?
No. Because we program the module to your VIN before shipping, it is a true plug-and-play installation. No need for a scan tool or a trip to the dealership.
Will this fix my ‘Service 4WD’ light?
If the TCCM is the source of the problem, then yes, this part will resolve the issue and turn off the warning light. Common causes for that light are a faulty TCCM, a bad transfer case encoder motor, or a faulty dash switch.
Where do I find my VIN?
Your VIN can be found on your vehicle’s registration, insurance card, or on a placard on the driver’s side of the dashboard visible through the windshield.
What if I have a different part number on my old module?
This module replaces a wide range of original part numbers. Please check the compatible part number list in the description. As long as your original number is on that list, this module will work perfectly.
