Restore Full Command of Your 4WD System
Is the dreaded “Service 4WD” light glowing on your dash? Are you struggling to shift between 2WD and 4WD, or hearing unsettling noises from your transfer case? A faulty Transfer Case Control Module (TCCM) is often the culprit, leaving your capable truck or SUV stuck in two-wheel drive. This isn’t just an inconvenience; it’s a loss of the core capability you rely on for tough jobs, harsh weather, and challenging terrain. This module is the definitive solution to restore the dependable performance you need from your GM vehicle.
Common Symptoms & Your Direct-Fit Solution
A failing TCCM can manifest in several ways, crippling your vehicle’s drivetrain. If you’re experiencing any of the following, this part is designed to be your fix:
- “Service 4WD” Message: The most common indicator that your system has detected a fault, often pointing directly to the TCCM.
- Inability to Shift Drivetrain Modes: The selector switch does nothing, leaving you unable to engage 4-High or 4-Low when you need it most.
- Incorrect Mode Indication: The light on your selector switch blinks or shows a different mode than the one you’re actually in.
- Diagnostic Trouble Codes (DTCs): Your mechanic may pull codes like C0327, C0306, or various U-codes (U0102, for example) indicating a loss of communication with the TCCM.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take a genuine GM module and professionally program it to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This crucial step ensures the module communicates perfectly with your truck’s other computers, like the ECM and BCM, recognizing all the specific options (RPO codes) your vehicle was built with. By installing our pre-programmed 2008-2013 Suburban 2500 Transfer Case Control Module, you bypass the expensive trip to the dealership for programming and get a true plug-and-play repair.

An Expert’s Note on VIN Programming
“As a technician, I’ve seen countless truck owners buy a used TCCM from a salvage yard, hoping for a cheap fix. They install it, and nothing works. Why? Because that module is still programmed for the donor truck’s specific options—its axle ratio, its tire size, its engine. It creates a communication nightmare. Our VIN programming service isn’t just a convenience; it’s the critical step that makes the repair work. We are essentially building a brand new ‘brain’ for your transfer case that speaks the exact language of your truck, ensuring a seamless and successful repair the first time.”

Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s VIN (Vehicle Identification Number) allows us to program the module with the exact software and vehicle-specific options (RPO codes) your truck or SUV was built with. This step is essential for the module to communicate correctly with your vehicle’s other computers and is what makes this a true plug-and-play part.
Is this part difficult to install?
For most of the listed GM trucks and SUVs, the TCCM is located on the driver’s side of the dashboard, making it accessible for a DIY-savvy owner. Because our module arrives pre-programmed, the physical installation is typically a simple ‘unplug and replace’ procedure with no special tools required. However, we always recommend consulting a repair manual for your specific model.
Will this fix my “Service 4WD” light?
If the fault is with the Transfer Case Control Module itself, then yes, this part is the definitive solution to clear that warning light and any related trouble codes. It’s the most common point of failure for these symptoms. However, you should always ensure other components like the transfer case encoder motor and selector switch are in good working order.

No problem. This module is a direct replacement for all the part numbers listed in the description, including 24261367, 12588096, and 24252878, among others. GM often updates part numbers over time; this unit is compatible with the entire listed range.
How quickly will I get my part after ordering?
We program and ship your module promptly after receiving your VIN. The key is to provide us with your VIN right after you complete your purchase to avoid any delays in the programming and shipping process.
What does the warranty cover?
This unit is backed by our one-year replacement warranty. In the unlikely event of a defect in the module within one year of purchase, we will provide a direct replacement.
