Restore Full Control Over Your Truck’s 4×4 System
As a technician with over two decades of experience under the hood of GM trucks, I’ve seen the frustration firsthand. The dreaded “Service 4WD” light pops on, and suddenly your dependable workhorse can’t switch into four-wheel drive when you need it most. More often than not, the culprit is a failed Transfer Case Control Module (TCCM). This isn’t just an inconvenience; it’s a reliability issue that can leave you stranded. That’s why we offer this direct-fit, fully programmed TCCM, designed to get your 2007-2014 Silverado 3500 PICKUP and other GM models back to full operational strength without a costly trip to the dealership.
The TCCM is the electronic brain of your 4×4 system. It takes your command from the dash switch and tells the transfer case motor exactly what to do. When it fails, communication breaks down, leaving your system inoperable or stuck in one mode. Our solution simplifies the repair. We take a quality replacement module and flash it with the latest GM software, specifically matched to your truck’s Vehicle Identification Number (VIN). This means when the part arrives, it’s truly plug-and-play. You bypass the expensive programming fees and diagnostic time at a service center, turning a potentially complex electronic repair into a manageable job for a DIYer or a quick install for a professional shop.
From the Diagnostic Bay
I remember a customer with a 2011 Sierra 2500 who came into my shop, completely frustrated. He used his truck for plowing snow and his 4WD had just quit right before a big storm. The dealer quoted him over $700 for a new TCCM and the required programming. He was looking at being without his truck for days. We diagnosed a failed module, ordered one of these pre-programmed units, and had it installed in under 30 minutes the next day. He was back in business for a fraction of the cost, just in time for the snow. That’s the value here—it’s not just a part, it’s a fast, reliable, and economical solution to a critical problem.
Is Your Truck Showing These Symptoms?
- ✔ “Service 4WD” or “Service Four Wheel Drive” message on the instrument cluster.
- ✔ Inability to shift between 2HI, 4HI, 4LO, or Auto modes.
- ✔ The 4WD selector switch lights are blinking or not illuminating at all.
- ✔ Grinding or clunking noises when attempting to engage the 4×4 system.
- ✔ Diagnostic Trouble Codes (DTCs) stored in the system, such as C0327, C0374, or various U-codes (e.g., U0102) indicating loss of communication with the TCCM.
A Straightforward Guide to Installation
Replacing the TCCM on your GM truck is a job most people can handle with basic tools. The module is typically located on the driver’s side, up under the dashboard near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the Module: On most of these trucks, the TCCM is mounted to a bracket to the left of the steering column. You may need to remove the lower dash panel for easier 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, making sure they click securely into place.
- Final Steps: Reinstall any dash 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 gone.

Frequently Asked Questions about the 2007-2014 Silverado 3500 TCCM
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to load the exact, vehicle-specific software from GM. This ensures the module communicates perfectly with your truck’s other computers (like the ECU and BCM) and that all 4WD functions operate as intended from the factory.
Is this part difficult to install myself?
No, this is a very DIY-friendly repair. The module is located under the driver’s side dash and is typically held in by a few bolts. With basic hand tools, most people can swap it out in under an hour. Since it comes pre-programmed, no special electronic tools are needed.
Will this fix the “Service 4WD” light on my dash?
In the vast majority of cases, a faulty TCCM is the cause of the “Service 4WD” light on these GM trucks. While other issues can cause it (like a faulty encoder motor or switch), this module is the most common point of failure and will resolve the issue if it’s the root cause.
What if my original part number isn’t 24249095?
That’s okay. GM uses many different part numbers for the same component. We’ve listed all compatible interchange part numbers in the description. As long as your original part number is on that list, this module will work perfectly as a replacement.
Is there a core charge for my old module?
No, there is no core charge or need to return your old, non-working part. The price you see is the final price for the replacement module.
