Is Your Truck Stuck in Two-Wheel Drive?
When the “Service 4WD” light illuminates your dashboard, it’s more than an annoyance—it’s a sign that your truck’s capability is compromised. A faulty Transfer Case Control Module (TCCM) is often the culprit, leaving you with flashing selector lights, an unresponsive 4×4 system, and a vehicle that can’t tackle the tough conditions it was built for.

An Expert’s Insight: Why VIN Programming is Non-Negotiable
As a technician, I’ve seen countless truck owners buy a used TCCM from a salvage yard, hoping for a cheap fix. The problem? That module is programmed for the donor vehicle’s specific options—axle ratios, tire size, and transfer case type. Installing it in your truck almost always leads to communication errors, erratic shifting, or a system that still won’t work. Our process eliminates that gamble. By flashing a clean module with your exact VIN, we ensure the unit is a perfect digital match for your truck’s configuration right out of the box. This programmed 24261367 transfer case control module is the only way to guarantee a correct and lasting repair.
Frequently Asked Questions
How does the programming process work?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this VIN to download the latest vehicle-specific software from GM and flash it directly onto the module before it ships. This makes the unit ready for installation upon arrival.
Where is the TCCM located on my vehicle?
On most compatible GM trucks and SUVs (like the Sierra, Silverado, and Tahoe), the Transfer Case Control Module is typically located behind the lower driver-side dashboard, to the left of the steering column. It’s usually accessible after removing the lower dash panel.
Is this a simple DIY installation?
Yes, for most individuals with basic mechanical skills. The installation involves disconnecting the battery, removing a few dash panels, and swapping the module. Since our unit is pre-programmed, there is no complex software or scanning required, making it a straightforward plug-and-play process.
Will this fix the “Service 4WD” light on my dash?
In the vast majority of cases, a faulty TCCM is the direct cause of the “Service 4WD” light and related symptoms. Replacing the old unit with this correctly programmed 24261367 transfer case control module will resolve the issue and extinguish the warning light, provided the module was the root cause of the failure.
What happens if I don’t provide my VIN?
We cannot ship the module without your VIN. The VIN-specific programming is the most critical part of our service and is essential for the module to function correctly in your vehicle. Your order will be held until the VIN is provided.
