Is the dreaded “Service 4WD” message lit up on your 2007-2014 GMC Yukon’s dashboard? Are you struggling with a four-wheel-drive system that won’t engage, or gets stuck between modes? You’ve come to the right place. As a technician with over two decades of experience under the hood of these GM trucks, I can tell you that a faulty Transfer Case Control Module (TCCM) is one of the most common culprits. This isn’t just an inconvenience; it’s a safety issue, especially when you need that 4×4 grip in bad weather. This TCCM, part number 24242480, is the reliable, long-term solution you need.
From the Diagnostic Bay: The Intermittent 4WD Ghost
A customer brought in his ’11 Yukon XL, frustrated because his 4WD would work one day and not the next. The selector switch lights would flash, and then nothing. He’d already replaced the transfer case encoder motor, but the problem persisted. On my scan tool, I saw intermittent communication loss codes with the TCCM. These modules, located under the driver’s side dash, are prone to internal electronic failures over time. We installed one of these VIN-programmed modules, and the problem was solved instantly. He saved hundreds by avoiding a dealership visit for programming, and his truck’s 4WD has been rock-solid ever since.
The Plug-and-Play Advantage: No Dealer Visit Required
The biggest headache with replacing electronic modules is the need for expensive, specialized programming. We eliminate that completely. When you purchase this 2007-2014 Yukon TCCM, you simply provide us with your vehicle’s VIN. We then flash the module with the latest, most stable software directly from GM. This ensures perfect communication with your truck’s other systems, like the ECU and BCM. The module arrives at your door ready for a straightforward installation, saving you time, money, and the hassle of scheduling a dealer appointment.

A Straightforward Guide to Installation
Replacing the TCCM on your Yukon is a job most DIYers can handle in under an hour with basic tools. It’s typically located under the dashboard on the driver’s side.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On most 2007-2014 Yukons, the TCCM is mounted to a bracket to the left of the steering column, up under the dash. You may need to remove the lower dash panel for easier access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old module. They have locking tabs, so be gentle. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed TCCM into place. Reconnect the electrical connectors, ensuring they click securely into position.
- Final Steps: Reinstall any trim panels you removed. Reconnect the negative battery terminal. Start the vehicle and test the 4WD selector switch to confirm proper operation.

Frequently Asked Questions
Why do you need my VIN?
Your VIN is crucial because it allows us to load the exact GM-specified software for your Yukon’s specific options (engine, transmission, transfer case model). This ensures seamless, plug-and-play functionality without any compatibility errors.
Is this a difficult part to install myself?
Not at all for most people with basic tools. The TCCM is typically located under the driver’s side dash and held in by a few bolts. The main challenge is accessing it, but no special procedures are required. Our installation guide above provides the key steps.
Will this fix the “Service 4WD” light on my dash?
In the vast majority of cases, yes. The “Service 4WD” light is the primary symptom of a failing TCCM. If you’ve ruled out other issues like the encoder motor or selector switch, this module is the most likely solution.
What happens if I install it without programming?
An unprogrammed module will not work. It won’t be able to communicate with your vehicle’s other computers, and your 4WD system will remain inoperative. Our pre-programming service saves you from this problem.
Is this compatible with other part numbers?
Yes, this module is a direct replacement for many part numbers, including 24261367, 12588096, 24239190, 24240487, 24241143, 24241970, 24243084, 24243085, 24249095, and 24252878.
