Regain Command of Your Truck’s 4×4 System
As a technician with over two decades of experience under the hood of GM trucks, I’ve seen it all. One of the most common and frustrating issues for owners of 2007-2013 Silverados is the dreaded “Service 4WD” light. It often means you’re stuck in one mode, unable to shift into 4-High for a slippery road or 4-Low for a tough job. The culprit is frequently a failed Transfer Case Control Module (TCCM), the electronic brain that manages your entire four-wheel-drive system. When it fails, your truck’s legendary capability is sidelined.
This isn’t just an inconvenience; it’s a matter of reliability. You bought a truck for its versatility, and a faulty TCCM takes that away. This replacement TCCM, part number 24242480, is the definitive solution. We take the biggest headache out of the repair process: programming. Simply provide us with your vehicle’s VIN at checkout, and our experts will flash the module with the latest GM software specific to your truck. It arrives at your door ready to install, saving you a costly trip to the dealership and hours of diagnostic guesswork.
From the Diagnostic Bay: The Intermittent 4WD Gremlin
I remember a 2011 Sierra 1500 that came into my shop with an intermittent 4×4 issue. The customer said it would work fine for weeks, then suddenly the “Service 4WD” light would pop on and the selector switch would be dead. He’d already replaced the switch and the transfer case encoder motor to no avail. After hooking up my scan tool, I saw communication loss codes (U-codes) that would come and go. Experience pointed me to the TCCM. We found that years of vibration and thermal cycles had caused microscopic cracks in the solder joints on the main processor. This is a classic failure point. A new, pre-programmed TCCM fixed it for good, restoring the driver’s confidence in his truck.
Is Your Truck Showing These TCCM Failure Symptoms?
A failing TCCM can manifest in several ways. If you’re experiencing any of the following, there’s a strong chance this module is your solution. In my shop, I’ve diagnosed hundreds of these failures based on these exact signs:
- ✔ “Service 4WD” or “Service Four Wheel Drive” message illuminated on the dashboard.
- ✔ Inability to shift the transfer case between 2HI, 4HI, 4LO, or Auto modes.
- ✔ The 4WD selector switch lights are off or flash without engaging the system.
- ✔ The vehicle is stuck in a single drive mode (e.g., stuck in 4HI).
- ✔ Diagnostic Trouble Codes (DTCs) related to transfer case communication or control, such as C0306, C0327, C0374, or various U-codes like U0102.
A Straightforward Guide to Your TCCM Installation
One of the best parts about this VIN-programmed module is its simple installation. For most DIYers with basic tools, this is a job you can tackle in your own driveway in under an hour.
- Safety First: Disconnect the negative terminal from your truck’s battery to prevent any electrical shorts.
- Locate the Module: On most of these GM trucks, the TCCM is located behind the lower dash panel on the driver’s side, to the left of the steering column. 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, so be gentle. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed TCCM into place. Reconnect the electrical connectors, ensuring they click securely 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 warning light should be gone, and all modes should function correctly.

Frequently Asked Questions
What does ‘VIN Programmed’ mean for me?
It means this module is a true plug-and-play solution. We use your Vehicle Identification Number (VIN) to load the exact software and calibrations your truck had when it left the factory, plus any available GM updates. This eliminates the need for an expensive programming session at a dealership, saving you time and money.
Will this definitely fix my ‘Service 4WD’ light?
The TCCM is the most common cause for the ‘Service 4WD’ light and associated shifting problems in these trucks. While other parts like the encoder motor or selector switch can fail, a faulty module is the prime suspect, especially if you have communication-related trouble codes. This module is the correct fix for a confirmed TCCM failure.
Where is the TCCM located on my 2007-2013 Silverado 1500?
The Transfer Case Control Module is typically mounted to a bracket behind the dashboard on the driver’s side, near the steering column. You will likely need to remove the plastic panel below the steering wheel (the knee bolster) to access it.
Is this a new or used part?
This is a high-quality, inspected, and tested recycled OEM part. Each module undergoes a rigorous inspection and is then programmed with the latest GM software for your specific VIN, ensuring reliable performance and perfect compatibility without the new part price tag.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a note to the seller during checkout or send it to us in a message immediately after ordering. We cannot program and ship your module without it.
