Restore Full Control Over Your Yukon’s 4WD System
Is that frustrating “Service 4WD” light glaring at you from the dash of your 2007-2014 GMC Yukon? Are you unable to switch between 2WD and 4WD, leaving you unprepared for bad weather or tough terrain? You’ve likely got a failed Transfer Case Control Module (TCCM). In my 20+ years as a technician, I’ve seen this exact issue countless times. The TCCM is the electronic brain of your four-wheel-drive system, and when it fails, it can sideline your truck’s capabilities. This isn’t just an inconvenience; it’s a matter of vehicle readiness and safety.
This is the definitive solution: a replacement TCCM, part number 24261367, that arrives at your door fully programmed to your vehicle’s specific VIN. We handle the complex part—flashing the module with the latest, most stable software from GM—so you don’t have to. Forget about scheduling a dealership appointment and paying extra for programming. With this module, you get a direct-fit, plug-and-play solution designed to get your 2007-2014 Yukon TCCM functioning perfectly again.
A Technician’s Notebook
I remember a 2011 Yukon Denali that came into the shop with an intermittent 4WD fault. The owner said the “Service 4WD” light would come on randomly, and sometimes the selector switch would be completely unresponsive. A quick scan pulled a U0102 code, ‘Lost Communication with Transfer Case Control Module.’ After verifying the wiring and connectors were clean and tight (always the first step!), we focused on the TCCM itself. These modules are often mounted in locations susceptible to moisture or voltage fluctuations, which can corrupt the internal software over time. We swapped in a VIN-programmed module like this one, and the problem was solved instantly. The customer was back on the road with reliable 4WD in under an hour.
Key Symptoms of a Failing TCCM
- ✔ “Service 4WD” or “Service Four Wheel Drive” message on the instrument cluster.
- ✔ Inability to shift the transfer case into or out of 4WD High, 4WD Low, or Auto mode.
- ✔ The 4WD selector switch lights are inoperative or flashing.
- ✔ Diagnostic Trouble Codes (DTCs) stored in the system, such as C0327, C0398, or U0102.
- ✔ Grinding or clunking noises when attempting to engage the 4×4 system.
- ✔ The vehicle is stuck in one drive mode (e.g., 4WD Low).
A Straightforward Guide to Installation
Installing your new 2007-2014 Yukon TCCM is a job most DIYers can handle with basic tools. The module 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.
- Access the Module: Remove the lower dash panel beneath the steering wheel. It’s usually held in by a few screws and clips.
- Locate the Old TCCM: Identify the old module. It’s a small black box with several electrical connectors plugged into it.
- Disconnect and Remove: Carefully unplug the wiring harnesses from the old TCCM. Then, unbolt or unclip the module from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed TCCM in the same location. Securely plug in all the electrical connectors. You should hear a ‘click’ as they lock into place.
- Final Steps: Reinstall the lower dash panel and 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 vehicle’s VIN (Vehicle Identification Number) allows us to program the TCCM with the exact software and calibrations specified by GM for your truck’s options. This ensures perfect compatibility and function, just like a part from the dealership, but without the extra cost and hassle of post-installation programming.
Is this a difficult part to install myself?
Not at all for most people with basic mechanical skills. Since the module comes pre-programmed, the installation is a simple plug-and-play process. It typically involves removing a dash panel, unplugging the old module, and plugging in the new one. No special tools are required.
Will this fix my “Service 4WD” light?
In the vast majority of cases where the TCCM is the source of the problem, yes. A faulty TCCM is the most common cause for the “Service 4WD” light on these GM trucks and SUVs. However, we always recommend a proper diagnosis to rule out other issues like a faulty encoder motor or selector switch.
What if my original part number isn’t 24261367?
This module is a direct replacement for a long list of older part numbers, including all the ones listed in the description. As long as your vehicle model and year are on our compatibility list, this module will work for you once programmed to your VIN.
Is there a core charge for my old module?
No, there is no core charge or need to return your old, non-functioning module. You can simply dispose of it after successfully installing the new one.
