Restore Your Truck’s 4×4 System with a Reliable, Pre-Programmed Module
If you’re staring at a ‘Service 4WD’ light on the dash of your Sierra 3500, you’re not alone. As a technician with over two decades of experience, I’ve seen countless hardworking trucks sidelined by a failed Transfer Case Control Module (TCCM). This isn’t just an annoying light; it means your truck’s four-wheel-drive system—the very feature you rely on for tough jobs and treacherous weather—is compromised. You might be unable to shift into 4HI or 4LO, or worse, be stuck in one mode. This isn’t just an inconvenience; it’s a reliability issue that can leave you stranded.
The solution is a dependable TCCM, but the dealership path often involves high costs and the hassle of getting your vehicle programmed on-site. We eliminate that step entirely. This module, part number 24261367, is the definitive fix for your 2007-2014 Sierra 3500 TCCM issues. We flash it with the latest GM software updates, specifically matched to your truck’s VIN before it ever leaves our facility. The result is a true plug-and-play component that gets you back on the road without the need for expensive diagnostic tools or a trip to the dealer.
From the Diagnostic Bay
I remember a contractor who brought in his ’11 Sierra 3500. His 4WD selector switch was dead, and the truck was stuck in 2WD right before a big snowstorm was forecast. He was worried about getting to his job sites. A quick scan showed a U0102 code—Lost Communication with Transfer Case Control Module. We checked the usual suspects: fuses and wiring. Everything looked fine. The culprit was the TCCM itself. These modules are often located under the dash where moisture can sometimes find its way in, causing internal corrosion on the circuit board. We replaced his faulty unit with a VIN-programmed module just like this one, and he was back in business in under 30 minutes, 4×4 system fully operational and ready for the snow.
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:
- âś” ‘Service 4WD’ or ‘Service Four Wheel Drive’ message on the instrument cluster.
- âś” Inability to switch between 2WD, 4HI, 4LO, or Auto modes.
- âś” The 4×4 selector switch lights don’t illuminate or flash without engaging.
- âś” Diagnostic Trouble Codes (DTCs) such as C0327, C0569, or U0102 stored in the system.
- âś” The transfer case seems to be stuck in neutral, causing a no-move condition.
A Straightforward Guide to Installation
One of the biggest benefits of our pre-programmed 2007-2014 Sierra 3500 TCCM is the simple installation process. You don’t need to be a master mechanic to get this done.
- 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, 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 the module from its bracket.
- Install the New Module: Bolt the new, pre-programmed TCCM into place and securely plug in the electrical connectors. You’ll hear a click when they are properly seated.
- Final Steps: Re-install any trim panels you removed and reconnect the negative battery terminal. Start the truck and test the 4WD selector switch to confirm proper operation.

Frequently Asked Questions
How does the VIN programming work?
After you place your order, you’ll need to provide us with your vehicle’s 17-digit VIN. We use this to load the exact GM-specified software and calibrations for your truck’s specific options, ensuring seamless communication and perfect functionality right out of the box.
Is this part difficult to install for a DIYer?
Not at all. Since the module comes pre-programmed, the installation is purely mechanical. It involves unplugging the old module and plugging in the new one. Basic hand tools are all you’ll need. Most customers complete the swap in under an hour.
What if this doesn’t fix my problem?
While this module is the most common cause of 4WD system failure, other issues like a faulty encoder motor, selector switch, or wiring problems can cause similar symptoms. We recommend confirming the diagnosis or consulting with a professional if you are unsure.
Will this part fix a specific error code?
Yes, this module is a direct solution for communication-related codes like U0102 (Lost Communication With TCCM) and internal failure codes. It can also resolve codes related to transfer case position sensor circuits (like C0327) that are internal to the module itself.
Is this a new or a used part?
This is a high-quality, inspected, and tested used OEM component. Each module is verified for full functionality before being programmed with fresh, vehicle-specific software, providing a reliable and cost-effective solution.
