Restore Your Truckโs 4WD Capability and Confidence
Is the โService 4WDโ light glaring at you from the dash? Are you unable to switch between 2WD, 4-High, or 4-Low? A faulty Transfer Case Control Module (TCCM) is often the culprit, leaving your capable GM truck or SUV stuck in two-wheel drive. This isn’t just an inconvenience; it’s a loss of the core capability you depend on for bad weather, tough jobs, or towing. This module is the definitive solution to get your four-wheel drive system back online, fully programmed and ready for a straightforward installation.

Expert Mechanic’s Insight
Before you condemn your TCCM, take a moment to check the simple things. On these GM platforms, poor ground connections can cause all sorts of electrical gremlins. Locate the main TCCM ground (typically on the frame rail below the driver’s door), remove it, and clean both the terminal and the frame contact point with a wire brush until you see shiny metal. A solid ground is critical for this module to function. If your problems persist after cleaning the ground, you can be confident that the Programmed Transfer Case Control Module 24241143 is the fix you need.
Frequently Asked Questions
Do I need to take this part to a dealer after installation?
Absolutely not. The main benefit of our service is that we program the module to your vehicle’s VIN before we ship it. This makes the installation a true plug-and-play process, saving you the time and significant expense of a dealership visit.
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is specific to your vehicle’s factory options.
What does a Transfer Case Control Module (TCCM) do?
The TCCM is the electronic brain of your 4WD system. It reads the input from your dash selector switch, processes that signal, and then commands the encoder motor on the transfer case to shift the gears, engaging or disengaging the front axle.
Is this the correct TCCM for my truck?
This module fits a wide range of 2007-2014 GM trucks and SUVs, including the Silverado, Sierra, Tahoe, Suburban, Yukon, and Avalanche. Please refer to the detailed fitment list on this page and match your original part number to the list of compatible numbers to ensure a perfect fit.
What happens if I don’t replace a faulty TCCM?
A faulty TCCM will leave you without functioning four-wheel drive. This can be a major safety and mobility issue in snow, ice, mud, or other low-traction situations. It can also prevent you from passing state vehicle inspections in some areas if the check engine or service light is on.
