Restore Your Truck’s 4WD System with a Reliable, Programmed TCCM
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 illuminates your dash, your selector switch becomes unresponsive, and suddenly, your capable 2007-2013 Silverado 1500 is stuck in two-wheel drive. More often than not, the culprit is a failed Transfer Case Control Module (TCCM). This isn’t just an inconvenience; it’s a loss of the core capability you rely on for tough jobs, slick roads, or off-road adventures. This module is the electronic brain of your 4×4 system, and when it fails, your truck loses its footing.
We offer a dependable and straightforward solution: a replacement TCCM, part number 24239190, that arrives at your door pre-programmed to your truck’s specific VIN. This crucial step eliminates the need for an expensive trip to the dealership for programming with a Tech 2 or MDI scan tool. We handle the complex part, so you can focus on the simple installation. By flashing the module with the latest GM software updates before it ships, we ensure optimal communication between the TCCM, the encoder motor, and the rest of your vehicle’s network, restoring the performance you expect from your Silverado.
From the Diagnostic Bay: The Case of the Intermittent 4WD
I remember a 2011 Silverado 1500 that came into my shop. The owner was frustrated because his 4WD would work one day and not the next. He’d already replaced the dash switch to no avail. We scanned it and pulled a U0102 (Lost Communication with TCCM) code. After checking the power and ground connections at the module harness—which were solid—we knew the issue was internal to the TCCM. Heat cycles and vibrations had likely caused a hairline crack in a solder joint on the circuit board. A new, properly programmed TCCM solved his problem permanently, and it’s a repair I’ve performed hundreds of times since on these otherwise bulletproof trucks.
Is Your Truck Showing These 4WD Symptoms?
A failing TCCM can manifest in several ways. If you’re experiencing any of the following, this module is the most likely solution for your 2007-2013 Silverado 1500 TCCM issues.
- ✔ “Service 4 Wheel Drive” or “Service 4WD” message on the driver information center (DIC).
- ✔ 4WD selector switch lights are off or flash intermittently.
- ✔ Vehicle will not shift into or out of 4-High, 4-Low, or Auto 4WD.
- ✔ Grinding or clunking noises when attempting to engage the 4×4 system.
- ✔ Diagnostic Trouble Codes (DTCs) stored in the system, such as C0327, C0374, C0569, or U0102.
- ✔ The truck is stuck in 4WD or, more commonly, stuck in 2WD.
A Straightforward Guide to TCCM Installation
One of the best parts about this repair is its simplicity. For most DIYers with basic tools, this is a 30-minute job. Here’s a quick guide to get your four-wheel drive working again.
- Safety First: Always disconnect the negative terminal from your truck’s battery to prevent any electrical shorts.
- Locate the Module: On most 2007-2013 Silverado and Sierra models, the TCCM is located on the driver’s side of the dashboard, up and to the left of the steering column. You may need to remove the lower dash 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. Firmly reconnect the electrical connectors, ensuring they click and are fully seated.
- Final Steps: Reinstall any dash panels you removed and reconnect the negative battery terminal. Start the truck and test your 4WD selector switch. The system should now function correctly.

Frequently Asked Questions
Do I need to do any programming myself?
No. This TCCM comes fully programmed to your vehicle’s VIN. It is a true plug-and-play solution. Just provide us with your VIN at checkout, and we handle the rest before shipping.
What is the difference between this and one from a local auto parts store?
Most modules from local stores come blank. You would still need to take your vehicle to a dealership or a well-equipped shop to have it programmed, adding significant cost and hassle to the repair. Our module is ready for installation right out of the box.
Is this part compatible with other part numbers?
Yes, this module is a direct replacement for several GM part numbers, including 24261367, 12588096, 24240487, and many others. It functions identically and is guaranteed to work if your vehicle is on the fitment list.
What causes the original 2007-2013 Silverado 1500 TCCM to fail?
Failure is commonly due to internal electronic issues. Over time, heat, cold cycles, and vehicle vibrations can cause solder joints on the circuit board to crack or electronic components like capacitors and resistors to fail, leading to communication errors.
Where is the TCCM located on my Silverado?
The Transfer Case Control Module is typically mounted behind the dashboard on the driver’s side, near the steering column. Access usually involves removing the lower dash panel (knee bolster).
