Restore Your Truck’s 4×4 Capability with a Reliable, Ready-to-Install Solution
If you’re staring at that frustrating ‘Service 4WD’ light on your 2007-2014 Yukon XL 1500, you know the feeling. Your truck’s four-wheel drive system is offline, leaving you without the traction and control you depend on, especially in bad weather or off-road conditions. For years in my shop, I’ve seen countless GM truck owners face this exact issue. The problem often points directly to a failed Transfer Case Control Module (TCCM), the electronic brain of your 4×4 system.
Historically, this repair meant a costly trip to the dealership for a new module and mandatory programming. We’ve eliminated that step. This TCCM is a direct-fit replacement for part number 24249095 and arrives at your door fully programmed to your vehicle’s specific VIN. We load the latest GM software updates, ensuring optimal performance and communication with your truck’s other systems. This isn’t just a part; it’s a complete, hassle-free repair.
From the Diagnostic Bay: The Intermittent 4WD Fault
A customer brought in his ’11 Sierra 1500, a vehicle that shares this exact Yukon XL 1500 TCCM platform. His complaint was tricky: the ‘Service 4WD’ light would come on randomly, and the selector switch would be dead. Sometimes a restart would fix it, sometimes not. He’d already replaced the selector switch and the transfer case encoder motor with no luck. After connecting my scan tool, I saw a U0102 code—Lost Communication with Transfer Case Control Module. Instead of a wiring issue, which is where many techs look first, I checked the TCCM’s power and ground. They were solid. Experience has taught me that these modules can fail internally, causing intermittent communication loss that’s maddening to diagnose. A new, pre-programmed module like this one fixed his truck in 15 minutes, saving him from hours of additional diagnostic labor.
Is Your Truck Exhibiting These 4WD Problems?
A failing TCCM can cause a range of symptoms. If you’re experiencing any of the following, this module is the likely solution for your 2007-2014 Yukon XL 1500 or related GM truck.
- ✔ ‘Service 4WD’ or ‘Service Four Wheel Drive’ message on the Driver Information Center (DIC).
- ✔ The 4WD selector switch lights are off or flash without engaging.
- ✔ Inability to shift between 2HI, 4HI, 4LO, or Auto 4WD modes.
- ✔ Vehicle is stuck in one 4WD mode and will not disengage.
- ✔ Diagnostic Trouble Codes (DTCs) stored, such as U0102, C0327, or other C-series and U-series codes related to the transfer case.
- ✔ A noticeable clunking or grinding sound when attempting to shift the transfer case.
Your Straightforward Installation Guide
One of the biggest benefits of this VIN-programmed module is the simple, plug-and-play installation. No special tools or dealer visits are required. You can do this right in your driveway.
- Safety First: Disconnect the negative terminal from your truck’s battery to prevent any electrical shorts.
- Locate the Module: The TCCM is typically located under the driver’s side dashboard, to the left of the steering column. You may need to remove a lower dash 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 Yukon XL 1500 TCCM in the same location. Securely plug in the electrical connectors until they click into place.
- Final Steps: Reinstall any dash panels you removed and reconnect the negative battery terminal. Start the vehicle and test the 4WD selector switch to confirm proper operation. The ‘Service 4WD’ light should be gone.

Your Questions Answered
Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the module with the exact software and calibrations specific to your truck’s factory options. This ensures seamless communication and perfect functionality, just like a part from the dealer, but without the hassle.
What does the TCCM actually do?
The Transfer Case Control Module acts as the computer for your 4WD system. It takes the input from your selector switch and commands the transfer case encoder motor to shift the vehicle into the desired drive mode (e.g., 2HI, 4HI).
Is this better than a used part from a salvage yard?
Absolutely. A used module will not be programmed for your specific VIN and may have the same internal faults as your old one. Our module is tested, loaded with the latest software for your vehicle, and provides a reliable, long-term repair.
Will I need to perform any other procedures after installation?
No. Because we program the module before shipping, there are no additional steps or relearn procedures required. Simply install it, and your 4WD system should be fully operational. It’s a true plug-and-play fix.
