An Expert’s Note on Programming: A common mistake we see is installing a used TCCM without proper programming. These modules are not ‘one-size-fits-all.’ Each one is coded to the original vehicle’s options (RPO codes) and VIN. Installing a mismatched module can lead to communication errors, persistent warning lights, or a completely inoperable 4WD system. Our VIN-programming service for the Programmed Transfer Case Control Module 24240487 bypasses this entire headache. We ensure the module you receive is a perfect electronic match for your truck, just as if it came from the factory floor.
By providing us with your VIN upon purchase, you are getting a component that is specifically tailored for your vehicle’s exact configuration. This attention to detail is what separates a temporary fix from a lasting, reliable repair. Get your Programmed Transfer Case Control Module 24240487 today and conquer any road or weather condition with confidence.
Frequently Asked Questions
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive your VIN, as the programming process is specific to your vehicle.
Is this part difficult to install?
For most GM trucks and SUVs, the TCCM is located under the driver’s side of the dashboard. Installation is straightforward for those with basic mechanical skills, typically involving the removal of a few trim panels and disconnecting electrical connectors. Because our module is pre-programmed, no further steps are needed after installation.
Will this definitely fix the “Service 4WD” light?
While the TCCM is the most common cause for the “Service 4WD” light and related symptoms, it’s always best to have the vehicle properly diagnosed. Other potential issues could include the transfer case encoder motor or the dash switch. However, if diagnostics point to a faulty module, this part is the definitive solution.
What happens if I install a module that isn’t programmed to my VIN?
Installing a non-programmed or incorrectly programmed TCCM will result in failure. The module will not be able to communicate with your truck’s other computers (like the BCM and ECM), and the 4WD system will remain inoperable. Our VIN-programming service is essential for a successful repair.
Does this module fit both electronic and manual shift transfer cases?
This module is for vehicles equipped with an electronic shift transfer case (with a knob or buttons on the dash). The specific transfer case option codes (like NQH or NQF) are important, and our VIN programming ensures the module is correctly configured for your vehicle’s specific hardware.
