An Expert’s Note on VIN Programming
Many owners try to save a few dollars by buying a used module from a salvage yard, only to find it doesn’t work. Here’s why: GM trucks use different transfer cases (identified by RPO codes like NQH or NQF) and have various electronic configurations. The TCCM must have the correct software for your specific setup. Our VIN programming process isn’t just a convenienceโit’s a necessity. We ensure the Programmed 24240487 Transfer Case Control Module you receive is perfectly matched to your truck’s DNA, preventing communication errors and guaranteeing a successful repair the first time.
Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) allows us to load the exact GM software calibration that matches your truck’s specific options, including the engine, transmission, and transfer case model. This step is crucial for a true plug-and-play installation and proper 4WD system function.
Is this a difficult part to install?
No, this is a straightforward installation for a DIY mechanic with basic tools. The TCCM is typically located under the driver’s side of the dashboard. The process involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors from the old module to the new one. Since it’s pre-programmed, no further steps are needed.
Will this fix the “Service 4WD” light?
In the vast majority of cases where the TCCM has failed, this part will resolve the issue and turn off the warning light after installation. However, the light can also be triggered by other issues like a faulty transfer case encoder motor or selector switch. We recommend confirming the module is the problem through proper diagnostics if you are unsure.
What if my old module has a different part number?
That’s very common. GM often updates part numbers over the years. This module, when programmed, is the correct service replacement for all the compatible part numbers listed in the description, such as 24261367, 12588096, 24239190, and others. As long as your vehicle is on the fitment list, this is the correct part.

This unit is backed by our one-year replacement warranty, giving you confidence in your repair.
