Restore Your Truck’s 4WD System with a Plug-and-Play Solution

You’re not alone. As a technician with over two decades of experience, I’ve seen this exact issue countless times. The Transfer Case Control Module (TCCM) is the electronic brain of your 4×4 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.

We offer a reliable Transfer Case Control Module, part number 24261367, that arrives at your doorstep fully programmed to your truck’s specific Vehicle Identification Number (VIN). This critical step eliminates the need for an expensive trip to the dealership for programming. You get a part that’s ready for installation right out of the box, loaded with the latest GM software updates to ensure optimal performance and communication with your truck’s other systems. This is the smart, efficient way to get your 2007-2013 Silverado 1500 TCCM working like new again.
From the Diagnostic Bay: The TCCM That Saved a Drivetrain
A customer brought in his ’11 Sierra 2500, convinced he needed a new transfer case. The truck was stuck in 4-HI, making grinding noises on tight turns, and the dash was lit up with the “Service 4WD” message. He was looking at a repair bill well over two thousand dollars. Before tearing into the heavy hardware, I hooked up my diagnostic scanner. It pulled a code C0327 for the transfer case encoder motor circuit. While this can point to the motor itself, my experience with these GM trucks told me to check the source: the TCCM. After a quick 5-minute swap with a known-good module, all the symptoms vanished. The selector switch worked perfectly, the code cleared, and the truck shifted smoothly between all modes. It wasn’t a catastrophic mechanical failure; it was a faulty electronic module. This pre-programmed TCCM provided the exact same fix, saving him a massive headache and a huge amount of money.
Is Your Truck Showing These Symptoms?
A failing TCCM can manifest in several ways. If you’re experiencing any of the following, this module is the likely solution for your GM truck or SUV.
- ✔ “Service 4WD” or “Service Four Wheel Drive” message on the instrument cluster.
- ✔ Inability to shift the transfer case into or out of 4-HI, 4-LO, or 2WD.
- ✔ The 4WD selector switch lights are inoperative or flashing.
- ✔ The 4×4 system engages or disengages randomly.
- ✔ Diagnostic Trouble Codes (DTCs) stored in the system, such as C0306, C0321, C0327, or communication codes like U0102.
DIY Installation: A Straightforward Guide
Replacing the 2007-2013 Silverado 1500 TCCM is a job most DIY enthusiasts can handle in under 30 minutes with basic tools. Because this module comes pre-programmed, there are no complex follow-up steps.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On most compatible trucks and SUVs, the TCCM is located on the driver’s side, up under 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 depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed TCCM in the same location. Securely plug in all the electrical connectors, ensuring they click into place.
- 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. The “Service 4WD” light should be off.

Frequently Asked Questions
How does the VIN programming process work?
It’s simple. After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians will use certified equipment to load the latest GM-approved software for your specific vehicle onto the module before it ships. This ensures it communicates perfectly with your truck’s systems right out of the box.
Is this part difficult to install myself?
Not at all for most people with basic hand tools. The module is typically located under the driver’s side dashboard and held in by a few bolts or clips. Since it’s pre-programmed, the job is purely mechanical: unplug the old one and plug in the new one. No computer relearn procedures are needed on your end.
What if this doesn’t fix my ‘Service 4WD’ light?
While the TCCM is the most common point of failure for these symptoms, other components like the transfer case encoder motor, the dash selector switch, or wiring can also be at fault. We highly recommend proper diagnostics. However, replacing the TCCM is often the most logical and cost-effective first step in the diagnostic process for these specific issues.
Will this work for a transfer case with option code NQH?
Yes. Our VIN-specific programming ensures the module is correctly configured for your vehicle’s exact options, including transfer cases with RPO codes NQH (Autotrac Active Transfer Case) or NQF (Electronic Shift Transfer Case).
Is this a new or used part?
This is a high-quality, inspected, and tested recycled OEM part that has been professionally programmed with the latest software. This provides the reliability of an original factory part at a significant cost saving compared to a new dealer part.
