Restore Your Truck’s All-Terrain Capability
As a technician with over two decades of experience under the hood of GM trucks, I’ve seen countless drivers frustrated by a flashing “Service 4WD” light, especially right before a winter storm or a planned off-road trip. The problem often isn’t a major mechanical failure in the transfer case itself, but rather its electronic brain: the Transfer Case Control Module (TCCM). This module is the command center for your 4×4 system, and when it fails, you’re left without the traction and control you depend on. This isn’t just an inconvenience; it’s a safety issue.
We offer a reliable and straightforward solution. This TCCM, compatible with part number 24239190, is the definitive fix for a faulty module in your 2007-2014 GMC Yukon and other compatible GM vehicles. The best part? We take the biggest headache out of the equation. Forget about costly dealership visits and programming fees. Simply provide us with your vehicle’s VIN at checkout, and we will program the module with the latest GM-certified software specifically for your truck. It arrives at your door ready for a true plug-and-play installation.
From the Diagnostic Bay: The Case of the Unresponsive 4WD
A customer brought in his 2011 Sierra 2500, complaining that his 4WD selector switch was dead—no lights, no response, nothing. He was convinced he needed a new switch and maybe even an encoder motor. After connecting my scan tool, I found a U0102 code: Lost Communication with Transfer Case Control Module. Instead of just throwing parts at it, I first checked the TCCM’s power and ground circuits, which were good. This told me the module itself was the likely culprit. We ordered a pre-programmed TCCM like this one. The installation took less than 20 minutes, and the moment we reconnected the battery, the selector switch lit up. A quick test confirmed full 2WD, 4-Hi, and 4-Lo functionality. The customer saved hundreds by avoiding unnecessary parts and dealer programming fees.
Is Your Truck Showing These Symptoms?
- ✔ The “Service 4WD” or “Service Four Wheel Drive” message is illuminated on your dashboard.
- ✔ The 4WD selector switch lights are inoperative or flashing.
- ✔ You are unable to shift the transfer case into or out of 4-Hi, 4-Lo, or 2WD.
- ✔ The vehicle feels like it’s stuck in 4WD, causing binding on dry pavement.
- ✔ Diagnostic scan tools show communication error codes, such as U0102, with the TCCM.
A Straightforward Guide to Installation
Replacing the 2007-2014 Yukon TCCM is a job most DIYers can handle in their own driveway. Since this unit comes pre-programmed, no special electronic tools are needed.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On most of these GM trucks and SUVs, the TCCM is located on the driver’s side of the dashboard, typically 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. Then, unbolt or unclip the old TCCM from its mounting bracket.
- Install the New Module: Mount the new, pre-programmed module in the same location and securely plug in all the electrical connectors. You’ll hear a click as they lock into place.
- Final Steps: Reinstall any trim panels you removed and reconnect the negative battery terminal. Start the vehicle and test the 4WD selector switch to confirm proper operation.

Frequently Asked Questions About The 2007-2014 Yukon TCCM
What does “pre-programmed to my VIN” mean?
It means we load the module with the specific software and calibrations for your truck’s exact configuration (engine, transmission, axle ratio) using your Vehicle Identification Number. This ensures it works perfectly right out of the box, with no need for a trip to the dealership for expensive programming.
Is this a difficult part to install myself?
Not at all. For most DIYers with basic hand tools, this is a very straightforward job. Since the programming is already done, it’s a simple plug-and-play swap. The most time-consuming part is often just accessing the module behind the dash panel.
Will this fix my “Service 4WD” light?
In a high percentage of cases, a faulty TCCM is the direct cause of the “Service 4WD” light. If you are experiencing other symptoms like an inoperative selector switch or communication codes, this module is the most likely solution. However, we always recommend proper diagnosis to rule out other issues like a faulty encoder motor or wiring problem.
Do I need to send my old module back?
No core charge or return is required for this part. You can keep or responsibly dispose of your old module.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your module until we receive and validate your VIN, as the programming is essential for the part to function.
