Restore Your 4WD with Confidence: A Pre-Programmed Solution
As a technician with over two decades of experience, I’ve seen the frustration firsthand: the dreaded “Service 4 Wheel Drive” message pops up on your dash, and suddenly your trusty GMC Yukon or Sierra can’t switch into 4WD when you need it most. Often, the culprit is a failed Transfer Case Control Module (TCCM). These modules are the brains of your 4×4 system, but they are susceptible to failure from voltage spikes, moisture, or simple electronic aging. The result? You’re left with a truck that’s lost one of its most important capabilities.
This isn’t just a used part pulled from a junkyard. This is a reliable TCCM, part number 24249095, that we program specifically to your vehicle’s VIN before it ever leaves our shop. This crucial step ensures seamless communication with your truck’s other computers and loads the latest GM software updates, resolving issues that older software might have. By ordering from us, you get a part that is truly plug-and-play, saving you a costly trip to the dealership and the hours of labor they charge for programming.
Case Study: The Yukon Stuck in Low Range
A customer brought in his 2011 Yukon XL, explaining it was stuck in 4-Low and was nearly undrivable on pavement. His local shop quoted him a massive bill, including hours of diagnostic time. After a quick scan, I saw a U0102 code—Lost Communication with Transfer Case Control Module. Instead of a complex wiring issue, my experience pointed straight to the TCCM. We swapped in one of our pre-programmed modules, and in under 15 minutes, the truck was shifting perfectly through all 4WD ranges. This simple part saved the customer over $500 in dealer fees and unnecessary diagnostics.

A Straightforward Guide to Installation
Installing your new 2007-2014 Yukon TCCM is a job most DIYers can handle in their own driveway. Since we’ve already done the programming, no special scan tools are needed.
- 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 a 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 pressed. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCCM into place. Firmly plug in the electrical connectors until they click, ensuring a secure connection.
- Final Steps: Reinstall any dash panels you removed and reconnect the negative battery terminal. Start the vehicle and test the 4WD selector switch to confirm proper operation.

Frequently Asked Questions
Frequently Asked Questions
Do I need to take this part to a dealer for programming?
Absolutely not. We program the module to your vehicle’s specific VIN before we ship it. This means it arrives ready for installation, saving you time and hundreds of dollars in dealer fees.
Where is the TCCM located on my 2011 Yukon?
On most 2007-2014 GM trucks and SUVs, including the Yukon, the TCCM is mounted to a bracket under the dashboard, to the left of the steering column.
Will this fix my “Service 4WD” light?
If the light is caused by a faulty or non-communicating TCCM, this part is the correct solution. It’s one of the most common reasons for that specific warning message on these vehicles.
What information do you need from me?
After you complete your purchase, we simply need you to provide your vehicle’s 17-digit VIN (Vehicle Identification Number). This allows us to load the correct GM software for your truck’s specific options.
Is this a reliable, long-term fix?
Yes. By using a quality module and flashing it with the latest, most stable software from GM, we are providing a component that is designed to restore original factory function for the long haul.
How is this different from a used part from a salvage yard?
A used part will not be programmed for your vehicle and may carry the same electronic faults as your old one. Our module is verified and programmed specifically for your VIN with updated software, ensuring a proper and lasting repair.
