Restore Your Yukon’s All-Weather Capability
Is that dreaded “Service 4WD” light staring back at you from the dash of your 2007-2014 GMC Yukon? When you can’t rely on your four-wheel drive, it compromises your vehicle’s safety and utility, especially in harsh weather or off-road situations. As a technician with over two decades of experience, I’ve seen countless GM trucks and SUVs sidelined by a faulty Transfer Case Control Module (TCCM). This isn’t just an inconvenience; it’s a critical failure that leaves you without the traction you depend on. This module is the brain of your 4×4 system, and when it fails, communication breaks down, leaving you stuck in two-wheel drive.
We offer a direct, reliable solution. This TCCM, compatible with part number 24249095, arrives at your door fully programmed to your Yukon’s specific Vehicle Identification Number (VIN). This means no expensive trips to the dealership for programming, no special scan tools, and no complicated procedures. It’s designed to be a true plug-and-play fix that gets you back in control. By providing us with your VIN at checkout, we ensure the module is loaded with the latest GM software updates, guaranteeing seamless integration and optimal performance from the moment you install it.
A Technician’s Notebook: The Intermittent 4WD Gremlin
I once had a 2011 Yukon in the bay with a frustrating issue: the 4WD would work one day and not the next. The owner was convinced the transfer case motor was bad. We checked the motor, and it tested fine. The selector switch on the dash also worked. After digging into the diagnostics, we found communication codes pointing to the TCCM. These modules can suffer from internal circuit board failures, often due to heat cycles and vibration, causing these intermittent faults that are so hard to pin down. Replacing the TCCM with a pre-programmed unit solved the problem permanently, saving the customer from needlessly replacing other expensive components.
Diagnosing a Faulty 2007-2014 Yukon TCCM
Confirming the TCCM is the root cause of your 4×4 issue is key to an effective repair. A failed module can mimic other problems, but there are several tell-tale signs. If your Yukon is experiencing any of the symptoms below, there’s a strong likelihood that the TCCM is the culprit. This module acts as the central command for engaging the front axle, and when it fails, the entire system is disabled.
Common Signs of TCCM Failure
- ✔ The “Service 4WD” or “Service Four Wheel Drive” message is constantly illuminated on your instrument cluster.
- ✔ Inability to shift the transfer case into 4HI or 4LO using the dash-mounted selector switch.
- ✔ The indicator lights on the 4WD selector switch do not light up or flash without engaging.
- ✔ Diagnostic Trouble Codes (DTCs) are stored in the system, such as C0327, C0398, or the common communication code U0102 (Lost Communication With Transfer Case Control Module).
- ✔ You hear a clicking or grinding noise from the transfer case area when attempting to shift, but no engagement occurs.
A Straightforward Guide to Installation
One of the best features of this VIN-programmed module is its simple installation. You don’t need to be a professional mechanic to get this job done. With basic hand tools, you can restore your 4WD system in under an hour.
- Safety First: Always begin by disconnecting the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On most 2007-2014 Yukons, the TCCM is located on the driver’s side, up under the dashboard to the left of the steering column. It’s a small black box with several electrical connectors.
- Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once unplugged, unbolt the module from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed TCCM into place. Firmly reconnect the electrical harnesses, ensuring they click and lock securely.
- 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. Start your Yukon and test the 4WD selector switch. The “Service 4WD” light should be off, and you should have full functionality back.

Frequently Asked Questions
Frequently Asked Questions
What does ‘VIN Programmed’ mean for me?
It means we load your vehicle’s unique VIN into the module before shipping. This ensures it communicates perfectly with your Yukon’s other computers (like the ECU and BCM) right out of the box, eliminating the need for dealership programming.
Is this part truly plug-and-play?
Yes. Because we handle all the programming, you simply need to physically swap the old module with this new one. No special tools or software procedures are required after installation.
Will this fix my ‘Service 4WD’ light?
If the light is caused by a faulty TCCM, then yes, this part is the specific solution. It’s the most common reason for that warning light on these vehicles.
Where is the TCCM located on my 2010 Yukon?
The Transfer Case Control Module is typically mounted under the driver’s side dashboard, to the left of the steering column. It is a black plastic box with multiple wiring harnesses connected to it.
What information do you need from me?
After you complete your purchase, you will need to provide us with your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we have programmed it with your VIN.
