Is Your Yukon’s 4WD Unreliable? Get a Permanent Fix.
Staring at that frustrating “Service 4WD” light on your 2007-2014 GMC Yukon dash? Are you unable to switch between 2WD and 4WD, leaving you unprepared for bad weather or rough terrain? You’re not alone. The Transfer Case Control Module (TCCM) is the electronic brain of your four-wheel-drive system, and when it fails, it can cause a host of problems. In my 20+ years as a technician, I’ve seen these modules fail due to internal circuit board issues, leading to communication errors that disable the entire system. This isn’t just an inconvenience; it’s a matter of vehicle capability and safety.
This is not a generic, one-size-fits-all part. This is a direct-fit replacement Transfer Case Control Module, part number 24241970, that arrives at your door fully programmed to your vehicle’s specific VIN. This crucial step ensures seamless communication with your truck’s other computers, like the ECM and BCM, right out of the box. You get a reliable, long-term solution without the exorbitant cost and hassle of a dealership visit for programming.
Case Study: A Tricky Diagnosis
A customer brought in his ’11 Sierra 2500 with the classic “Service 4WD” light. His selector switch was dead, and the truck was stuck in 2WD. He’d already replaced the switch and the transfer case encoder motor with no luck. A quick scan with my pro-level tool showed a U0102 code—Lost Communication with Transfer Case Control Module. Instead of just throwing more parts at it, we checked the TCCM. After confirming power and ground were good, it was clear the module itself was the culprit. We installed one of these pre-programmed modules, and in under 30 minutes, the 4WD system was fully operational. He was thrilled to have his truck’s capability back without a massive dealership bill.
Is Your Truck Showing These 4WD Warning Signs?
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 TCCM issues:
- ✔ “Service 4WD” or “Service Four Wheel Drive” message on the instrument cluster.
- ✔ Inability to shift into or out of 4-High or 4-Low.
- ✔ The 4WD selector switch lights are inoperative or flashing.
- ✔ The vehicle is stuck in 4WD or 2WD mode.
- ✔ Diagnostic Trouble Codes (DTCs) stored, such as U0102, C0327, or C0306.
- ✔ A noticeable delay or grinding noise when attempting to engage the 4WD system.
A Straightforward Guide to Installation
Replacing the TCCM is a job most DIYers can handle with basic tools. Because we program it beforehand, there are no special computer tools needed for the installation itself. The module is typically located on the driver’s side, up under the dashboard.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the Module: On most of these GM trucks and SUVs, the TCCM is mounted to a bracket to the left of the steering column, behind the lower dash panel. You may need to remove the knee bolster panel for access.
- 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.
- Install the New Module: Bolt your new, pre-programmed TCCM into place. Securely plug in the electrical connectors until they click.
- Final Steps: Re-install any trim panels you removed. Reconnect the negative battery terminal. Turn the ignition to the ‘On’ position (without starting the engine) and test the 4WD selector switch. The lights should illuminate, and you should hear the transfer case actuator engage as you switch modes.

Frequently Asked Questions
How does the VIN programming work?
After you place your order, you’ll provide us with your vehicle’s 17-digit VIN. Our technicians use this number to download the latest official GM software for your specific vehicle build and flash it directly onto the module before shipping. This ensures it works perfectly upon installation.
Is this really a plug-and-play part?
Yes. Because we handle the programming, you will not need to take your vehicle to a dealer or mechanic for any additional computer work. Simply install the module, and your 4WD system will be restored. It’s the most straightforward way to fix this common issue.
Where is the TCCM located on my 2011 Yukon?
On the 2007-2014 Yukon, Tahoe, Suburban, and GM pickup trucks, the Transfer Case Control Module is located inside the cabin, behind the dashboard on the driver’s side, to the left of the steering column.
Why is this better than a used part from a junkyard?
A used module from a salvage yard will be programmed to the donor vehicle, not yours, and will not work correctly. It also carries the risk of having the same internal flaws as your failed unit. Our module is inspected for quality and contains fresh, updated software specific to your VIN for guaranteed performance.
Do I need to send my old module back?
No, there is no core charge or need to return your old, failed part. You can recycle it locally or simply dispose of it.
