Regain Control of Your 4×4 System with a Reliable, Pre-Programmed TCCM
Is the dreaded “Service 4WD” light glaring at you from the dashboard of your 2008-2014 Suburban 1500? Are you unable to switch between 2WD and 4WD, or worse, stuck in one mode? You’re not alone. The Transfer Case Control Module (TCCM) is the electronic brain of your four-wheel-drive system, and when it fails, it can leave you without the traction and control you depend on. This isn’t just an inconvenience; it’s a safety concern, especially in poor weather or off-road conditions.
Forget the expensive trip to the dealership and the hassle of post-installation programming. We offer a direct-fit, plug-and-play solution. This TCCM, part number 24241970, arrives at your door pre-programmed with the latest GM software, specifically flashed to your vehicle’s unique VIN. This ensures seamless communication and perfect functionality right out of the box, restoring your truck’s capabilities quickly and affordably.
A Technician’s Notebook: The Case of the Stubborn Sierra
I remember a customer bringing in his ’11 Sierra 2500, completely frustrated. His 4WD selector switch was unresponsive, and the truck was stuck in 4-Hi just before a big snowstorm. He’d already replaced the dash switch on a friend’s advice, with no luck. A quick scan with my tool showed a U0102 code—Lost Communication with Transfer Case Control Module. Instead of a complex wiring chase, experience pointed me straight to the TCCM under the driver’s side dash. We ordered a VIN-programmed module just like this one. The installation took less than 15 minutes, and the moment we reconnected the battery, the system came back to life. The customer was thrilled to have his truck’s capability back for less than half of what a dealership quoted him for diagnostics and programming. This is the exact fix for that common scenario.
Is Your Truck Exhibiting These 4WD Faults?
A failing TCCM often presents clear symptoms. If you’re experiencing any of the following, this module is the likely solution for your 2008-2014 Suburban TCCM issues:
- ✔ “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 don’t illuminate or flash without engaging.
- ✔ A grinding or clunking noise when attempting to shift the transfer case.
- ✔ Diagnostic Trouble Codes (DTCs) stored in the system, such as C0306, C0327, C0569, or U0102.
A Straightforward Guide to Installation
One of the biggest benefits of this module is its simple, DIY-friendly installation. No specialized tools are needed, and you can have your 4WD system working again in under 30 minutes. Here’s a general guide:
- Safety First: Disconnect the negative terminal from your truck’s battery to prevent any electrical shorts.
- Locate the Module: The TCCM is typically located under the driver’s side of 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 release tabs that need to be pressed. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCCM into place and securely reconnect the electrical connectors. You should hear a click as they lock in.
- Final Steps: Reinstall any trim panels you removed and reconnect the negative battery terminal. Start the vehicle and test the 4WD selector switch to confirm proper operation.

Why do you need my VIN?
Your vehicle’s VIN (Vehicle Identification Number) allows us to flash the TCCM with the specific software and calibrations for your truck’s options (engine, transmission, transfer case model). This makes the module a true plug-and-play part and prevents compatibility issues.
What does the TCCM actually do?
The Transfer Case Control Module is a small computer that reads inputs from the 4WD selector switch, vehicle speed sensors, and other systems. It then commands the transfer case encoder motor to shift the vehicle into the desired drive mode (e.g., 2WD, 4WD High). When it fails, this communication breaks down.
Will this fix my “Service 4WD” light?
In the vast majority of cases, yes. A faulty TCCM is the most common cause of the “Service 4WD” warning on these GM trucks and SUVs. This pre-programmed module is designed to be the definitive fix for module-related failures.
Is this a difficult part to replace myself?
Not at all. For most DIYers with basic hand tools, this is a very straightforward job that can be completed in under 30 minutes. Its location under the dash is accessible, making it a simple unbolt-and-unplug process.
Is this compatible with other part numbers?
Yes, this module is a direct replacement for numerous GM part numbers, including 24261367, 12588096, 24239190, 24240487, 24241143, 24242480, 24243084, 24243085, 24249095, and 24252878.
