Restore Your Truck’s 4×4 Power without the Dealership Hassle
As a technician with over two decades of experience, I’ve seen the frustration firsthand: you get in your powerful Sierra 3500, ready for a tough job or a weekend adventure, and you’re greeted by that dreaded “Service 4WD” light. Your four-wheel drive is unresponsive, stuck in one mode, or just won’t engage at all. The culprit is often a failed Transfer Case Control Module (TCCM), the electronic brain of your 4×4 system. This isn’t just an inconvenience; it’s a loss of the core capability you paid for in a heavy-duty truck.
This is where our solution comes in. We’re offering a direct-fit replacement TCCM, part number 24261367, for your GM truck or SUV. But here’s the critical difference: we handle the most complex part of the job for you. Before we ship it, we program the module with the latest GM software, specifically matched to your vehicle using your VIN. This means no expensive trip to the dealership for programming, no special scan tools required. You get a part that’s ready to install right out of the box, saving you significant time and money.
A Technician’s Notebook: The Misleading Sensor Code
A customer brought in a 2011 Silverado 2500, a sister truck to the Sierra, with the “Service 4WD” light on. The code pointed to a transfer case encoder motor sensor. A less experienced tech might just replace the encoder motor—an expensive part. However, after 20 years, I know better. I checked the TCCM communication lines and found nothing. The module was completely dead. A quick voltage check confirmed it had power and ground, but the internal processor had failed. We installed one of our pre-programmed modules, and the 4WD system came back to life instantly. The original sensor code was a ghost, triggered by the failing TCCM. This is a classic case where experience prevents wasting money on the wrong parts.
Is Your Truck Showing These TCCM Failure Signs?
A faulty TCCM can manifest in several ways. If you’re experiencing any of these, this module is your most likely solution.
- ✔ “Service 4WD” or “Service Four Wheel Drive” message on your driver information center (DIC).
- ✔ Inability to switch between 2WD, 4HI, and 4LO.
- ✔ The 4×4 selector switch lights don’t illuminate or flash without engaging.
- ✔ Diagnostic Trouble Codes (DTCs) stored in the system, such as U0102 (Lost Communication with TCCM).
- ✔ The transfer case seems to get stuck in neutral or one drive mode.
A Straightforward Guide to Installation
Installing your new 2007-2014 Sierra 3500 TCCM is a job most DIYers can handle in their own driveway. Since we’ve pre-programmed it, the process is purely mechanical.
- Safety First: Disconnect the negative terminal from your truck’s battery to prevent any electrical shorts.
- Locate the Module: The TCCM is typically located on the driver’s side of the dashboard, up and to the left of the steering column, often attached to a metal bracket. You may need to remove the 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 depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed TCCM onto the bracket and securely plug in the electrical connectors. You’ll hear a click as they lock into place.
- Final Steps: Reinstall any dash panels you removed and reconnect the negative battery terminal. Start the truck and test your 4WD selector switch. The “Service 4WD” light should be gone, and all functions restored.

Frequently Asked Questions
What exactly is VIN programming?
VIN programming involves loading the module with the specific software and calibrations for your truck’s exact configuration (engine, transmission, axles, etc.). We use your Vehicle Identification Number (VIN) to access the correct GM software file, ensuring perfect communication with your truck’s other computers and eliminating the need for a dealer visit.
Is this part difficult to install myself?
Not at all for most people with basic tools. The module is located inside the cab, under the driver’s side dashboard. Since the programming is already done, it’s a simple plug-and-play process of unplugging the old module and plugging in the new one. No special electronic tools are needed.
Will this fix my “Service 4WD” light?
In the vast majority of cases where the symptoms match (no 4WD engagement, flashing lights, communication codes), a failed TCCM is the root cause. This pre-programmed module is the direct and reliable fix for that failure.
How do I provide my VIN after purchase?
After you complete your purchase, you will receive an email with instructions on how to send us your 17-digit VIN. You can also add it as a note during checkout. We cannot ship the module until we receive your VIN to perform the programming.
Is this compatible with other part numbers?
Yes, this module replaces a long list of previous GM part numbers, including 12588096, 24239190, 24240487, 24241143, 24241970, 24242480, 24243084, 24243085, 24249095, and 24252878. We ensure it has the latest software available.
