Get Your 4WD System Back in Action
Is that frustrating “Service 4WD” light staring you down every time you start your truck? Are you unable to switch between 2WD and 4WD, leaving you unprepared for bad weather or tough terrain? A faulty Transfer Case Control Module (TCCM) is often the culprit, but a simple replacement isn’t enough. This module is the solution—a direct-fit TCCM that arrives at your door fully programmed to your vehicle’s specific VIN. We handle the complex programming so you can perform a simple, straightforward installation and restore the rugged capability you depend on.
Common Symptoms & Your Solution
If you’re experiencing any of the issues below, a failing TCCM is the likely cause. This module is engineered to be the definitive fix for:
- Persistent “Service 4WD” or “Service Four Wheel Drive” message on the dash
- Inability to shift between 2HI, 4HI, and 4LO
- 4WD selector switch lights are inoperative or flashing
- Vehicle is stuck in 4WD or 2WD mode
- Diagnostic Trouble Codes (DTCs) such as C0306, C0321, C0327, C0374, or U0102
By installing our Programmed 24261367 TCCM, you are not just replacing a part; you are restoring a critical vehicle system with a component that’s ready to communicate perfectly with your truck’s electronics right out of the box.

An Expert’s Note on VIN Programming
As a technician, I’ve seen countless vehicle owners try to save a few dollars by installing a used or non-programmed TCCM. The result is almost always more headaches. In modern GM vehicles, the TCCM must communicate perfectly with the Engine Control Module (ECM) and Body Control Module (BCM). Without the correct VIN-specific software, this communication fails, leading to persistent error codes, incorrect operation, or a completely non-functional 4WD system. Our process ensures this critical electronic “handshake” happens correctly the first time, saving you time, money, and frustration.
Frequently Asked Questions
What is a TCCM and what does it do?
The Transfer Case Control Module (TCCM) is a small computer that acts as the brain for your vehicle’s four-wheel-drive system. It reads input from the driver (via the 4WD switch), vehicle speed sensors, and other systems to engage and disengage the transfer case, allowing you to shift between 2WD and 4WD.
Why is VIN programming so important for this part?
VIN programming loads your vehicle’s specific software and configuration into the module. This ensures it communicates correctly with all other computers in your truck, like the engine and transmission controllers. A non-programmed module will not work correctly and can cause additional system faults. We do this for you so it’s a true plug-and-play part.
Is this a difficult part to install?
For most DIYers with basic tools, this is a relatively simple installation. The TCCM is typically located under the driver’s side of the dashboard. The process involves disconnecting the battery, removing a few trim panels, unplugging the electrical connectors from the old module, unbolting it, and then reversing the process with the new one. Since our Programmed 24261367 TCCM requires no further steps, the physical replacement is the entire job.
How do I provide my VIN after purchase?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will provide clear instructions on how to do this. We cannot ship your part until we receive the VIN, as the programming is a critical step.
Will this clear the “Service 4WD” light on my dash?
Yes, in the vast majority of cases where the TCCM is the root cause of the problem, installing this correctly programmed module will resolve the issue and the warning light will turn off after the vehicle’s computer systems re-check. It is always a good practice to clear any stored fault codes with a scan tool after installation.
What if I have a different part number on my old module?
This module replaces a wide range of original part numbers, including 12588096, 24239190, 24240487, and many others listed in the description. As long as your vehicle make, model, and year are on our compatibility list, this part will work, as it will be loaded with the correct software for your VIN.
