- Flashing Selector Lights: The lights on your 4WD switch blink but never engage the selected mode.

Expert Insight from the Shop Floor: A common mistake we see is mechanics or DIYers chasing ghosts by replacing the dash switch or the transfer case encoder motor when the TCCM is the real culprit. The TCCM is the ‘brain’ of the 4WD system. If the switch lights are dead or flashing without action, it’s often because the brain isn’t sending the right signals. By providing a properly programmed 24261367 TCCM, we eliminate the guesswork and ensure all components in the system can communicate correctly, just as the factory intended.
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as the programming is essential for the part to function in your vehicle.
Is any additional programming required after installation?
No. This module is a true plug-and-play solution. Because we program it to your specific VIN before shipping, you just need to disconnect the old module and connect this new one. No dealer visits or special tools are necessary.
Where is the TCCM located on my vehicle?
On most compatible GM trucks and SUVs like the Silverado, Sierra, and Yukon, the TCCM is typically located behind the lower dashboard panel on the driver’s side, to the left of the steering column. It’s a small black box with a few electrical connectors.
Will this fix my “Service 4WD” light?
In the vast majority of cases where the TCCM is the faulty component, yes. This module is the most common solution for the “Service 4WD” message and associated symptoms. However, you should always verify that other components like fuses and wiring are in good condition.
What makes this programmed module better than a used one from a junkyard?
A used module from another vehicle will not work correctly because it is programmed to that vehicle’s specific options and VIN. Our new, professionally programmed TCCM ensures perfect compatibility and is loaded with the latest software, preventing the known issues that may have caused the original part to fail.
