Restore Full Control Over Your Yukon’s 4WD System
Is the dreaded “Service 4WD” light glowing on your dashboard? Are you struggling with a GMC Yukon XL 2500 that won’t shift into or out of four-wheel drive? You’re not alone. The Transfer Case Control Module (TCCM) is the electronic brain of your 4×4 system, and when it fails, it can leave you stranded in the wrong drive mode. This isn’t just an inconvenience; it’s a capability issue, especially when you need that extra traction in bad weather or off-road conditions. This module is the definitive solution, restoring the reliable performance you expect from your truck.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the hassle and expense out of the repair by pre-programming this TCCM specifically to your vehicle’s VIN. When it arrives, it has the latest GM software updates already loaded. This means no expensive trip to the dealership for programming, no special scan tools required—just a straightforward installation to get you back on the road with confidence. This is the most efficient way to fix common 4WD electronic failures in your GM truck or SUV.
From the Diagnostic Bay
I remember a customer with a 2011 Sierra 2500—same platform as your Yukon—who was completely frustrated. His 4WD switch was dead, and the truck was stuck in 2HI right before a big snowstorm. He’d already replaced the selector switch and the transfer case motor with no luck. After a quick scan, we found code U0102, ‘Lost Communication with TCCM.’ It’s a classic symptom. These modules, located under the driver’s side dash, are prone to internal electronic failure over time. We installed one of our pre-programmed units, and in less than 30 minutes, the 4WD system was fully operational. He was relieved to have his truck’s capability back without a costly dealership bill.
Is Your Yukon Exhibiting These 4WD Faults?
A failing TCCM can cause a range of frustrating symptoms. If you’re experiencing any of the following, this module is the likely solution for your 2008-2013 Yukon XL 2500 TCCM issues:
- ✔ “Service 4WD” or “Service Four Wheel Drive” message on the instrument cluster.
- ✔ The 4WD selector switch lights are off or flash but won’t engage a mode.
- ✔ Vehicle is stuck in 2WD, 4WD High, or 4WD Low.
- ✔ Inability to switch between any of the drive modes.
- ✔ Diagnostic Trouble Codes (DTCs) stored, such as C0327, C0398, or the common communication code U0102.
- ✔ A noticeable delay or no response at all when you turn the 4WD knob.
A Straightforward Guide to Installation
One of the biggest benefits of this VIN-programmed module is the simple, plug-and-play installation. You can do this at home with basic hand tools.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: The TCCM is typically located under the driver’s side of the dashboard, to the left of the steering column. You may need to remove the 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 unplugged, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCCM into place. Reconnect the electrical connectors, ensuring they click securely into place.
- Final Steps: Reinstall any dash panels you removed. Reconnect the negative battery terminal. Start the vehicle and test the 4WD selector switch. The “Service 4WD” light should be off, and all modes should function correctly.

Frequently Asked Questions
How does the VIN programming work?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. Our technicians use this number to access the latest official GM software for your specific vehicle configuration. We then flash this software onto the module before shipping it to you, making it a true plug-and-play part.
Do I need any special tools for this job?
No. Basic hand tools like a socket set and a trim removal tool are all that’s typically required. Because the module is pre-programmed, you do not need any expensive diagnostic scan tools for the installation.
Is this part compatible with other part numbers?
Yes, this TCCM is a direct replacement for several GM part numbers, including 24261367, 12588096, 24239190, 24240487, 24241143, 24241970, 24242480, 24243085, 24249095, and 24252878. Our module, part 24243084, will function correctly in place of these.
What if this doesn’t fix my problem?
While the TCCM is the most common point of failure for these symptoms, other components like the transfer case encoder motor or the selector switch can also be at fault. We always recommend a proper diagnosis. However, if your symptoms match the ones described and you have communication codes like U0102, this module is the most probable solution.
Where is the TCCM located on my Yukon XL 2500?
On the 2008-2013 Yukon XL 2500, the Transfer Case Control Module is mounted under the dashboard on the driver’s side, typically to the left of the steering column and above the emergency brake pedal assembly.
