Is the dreaded ‘Service 4WD’ light glaring at you from the dash of your GMC Yukon? Are you unable to switch drive modes, leaving you stuck in 2WD when you need 4WD the most? You’ve likely diagnosed a failed Transfer Case Control Module (TCCM). For years, this meant a costly trip to the dealership for the part and another expensive fee for programming. We’ve eliminated that step. This TCCM is the definitive, hassle-free solution to restore your vehicle’s four-wheel-drive functionality.
As a technician with two decades of experience, I’ve seen countless GM trucks and SUVs roll into the bay with these exact symptoms. The TCCM is the electronic brain of your 4×4 system, and when it fails, it can cause frustrating and unpredictable behavior. This isn’t just an inconvenience; it’s a matter of vehicle capability and safety, especially in poor weather or off-road conditions. Our solution is simple: provide us with your vehicle’s VIN during checkout, and we’ll program this module with the latest GM software specifically for your truck. It arrives at your door ready for a straightforward, plug-and-play installation.
A Technician’s Notebook
I remember a 2011 Sierra 2500 that came in, a contractor’s workhorse. The 4WD selector switch was completely dead—no lights, no response. The owner was convinced he needed a new switch. After a quick scan, I found a U0100 code—Lost Communication with the TCCM. Instead of just replacing parts, I checked the TCCM’s power and ground connections under the dash, which were solid. This confirmed the module itself was internally fried, a common issue from voltage spikes or simple electronic fatigue over time. We installed a VIN-programmed module just like this one, and the system came back to life instantly. It saved him from buying a switch he didn’t need and got his truck back to work the same day.
Is Your Truck Showing These Symptoms?
A failing TCCM can manifest in several ways. If you’re experiencing any of the following, this module is the likely solution for your 2007-2014 Yukon TCCM issues:
- ✔ ‘Service 4WD’ or ‘Service Four Wheel Drive’ message on the instrument cluster.
- ✔ Inability to shift the transfer case into or out of 4-Hi, 4-Lo, or 2WD.
- ✔ Diagnostic Trouble Codes (DTCs) such as C0327, C0306, or U0100 stored in the system.
- ✔ The 4WD selector switch lights are inoperative or flash without engaging.
- ✔ A noticeable delay or clunking sound when the system does attempt to engage.
A Straightforward Guide to Installation
One of the biggest benefits of our pre-programmed module is the ease of installation. You don’t need advanced diagnostic tools or a trip to the dealer. With basic hand tools, you can get this job done in your own driveway.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the Module: On most GM trucks and SUVs from this era, the TCCM is located on the driver’s side, up under the dashboard to the left of the steering column.
- Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCCM into place. Securely plug in the electrical connectors, making sure they click to confirm they are fully seated.
- Final Steps: Reconnect the negative battery terminal. Turn the ignition to the ‘On’ position (without starting the engine) and wait about 30 seconds for the system to initialize. Test the 4WD selector switch to confirm proper operation.

Frequently Asked Questions
What exactly does ‘VIN Programmed’ mean?
It means we load the module with the specific software and calibrations for your exact vehicle using the Vehicle Identification Number (VIN) you provide. This makes it a true plug-and-play part, eliminating the need for dealer programming.
Do I need to send my old module back?
No, there is no core charge or requirement to return your old, faulty TCCM.
Is this compatible with other part numbers?
Yes, this module is a direct replacement for multiple part numbers, including 24261367, 12588096, 24239190, 24240487, and others listed in the product details. It contains the most current software available.
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 the module until we have this information to perform the programming.
What if this doesn’t fix my problem?
While this module solves the most common 4WD issues, other components like the transfer case encoder motor or the selector switch can also fail. We recommend proper diagnosis. If you see communication codes like U0100, the TCCM is the most probable cause.
