If you’re staring at that frustrating ‘Service 4WD’ light on your 2007-2014 GMC Yukon XL 1500, you’ve come to the right place. As a technician with over two decades of experience, I’ve seen countless GM trucks and SUVs sidelined by a failed Transfer Case Control Module (TCCM). This isn’t just an annoyance; it’s the loss of your vehicle’s all-terrain capability. This module is the electronic brain of your 4×4 system, and when it fails, you’re left stuck in two-wheel drive, often when you need four-wheel drive the most.
We offer a simple, reliable solution: a replacement TCCM, part number 24242480, that arrives at your door fully programmed to your vehicle’s specific VIN. By flashing it with the latest GM software updates before shipping, we eliminate the need for an expensive trip to the dealership for programming. This is a direct-fit, plug-and-play solution designed to get your truck’s 4×4 system back online quickly and affordably.
A Technician’s Notebook: The Pre-Winter Rush
I remember a customer rushing into the shop one October afternoon with his ’12 Yukon XL. A big snowstorm was forecast for the weekend, and his ‘Service 4WD’ light had just come on. He couldn’t get the truck to shift into 4HI. A quick scan pulled a U0102 code—Lost Communication with Transfer Case Control Module. After verifying power and ground at the connector, we confirmed the TCCM was dead. The dealership quoted him a hefty price and a two-day wait. Instead, we provided him with one of our VIN-programmed modules. He installed it himself in under 30 minutes in his driveway and had reliable 4WD restored well before the first snowflake fell. That’s the peace of mind we deliver.
Is Your Truck Showing These 4WD 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 XL 1500 TCCM problems:
- ✔ ‘Service 4WD’ or ‘Service Four Wheel Drive’ message on the instrument cluster.
- ✔ The 4×4 selector switch lights are inoperative or flashing.
- ✔ Inability to switch between 2HI, 4HI, 4LO, or Auto modes.
- ✔ Vehicle is stuck in one drive mode (e.g., 4HI or 2WD).
- ✔ Diagnostic Trouble Codes (DTCs) stored, such as C0306, C0327, C0398, or U0102.
A Straightforward Guide to Installation
One of the best parts of this solution is its simplicity. No specialized tools are needed. The TCCM is typically located under the driver’s side of the dashboard, to the left of the steering column.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On your Yukon XL 1500, find the TCCM mounted to a bracket under the dash, near the emergency brake pedal assembly.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old module. They have locking tabs that need to be depressed. Then, unbolt the module from its mounting bracket (typically a couple of 10mm nuts).
- Install the New Module: Mount your new, pre-programmed TCCM onto the bracket and securely fasten the nuts.
- Reconnect and Test: Plug the electrical connectors firmly into the new module. Reconnect the negative battery terminal. Turn the ignition on and test the 4×4 selector switch to confirm all modes engage correctly. The ‘Service 4WD’ light should now be off.
