An Expert’s Note on VIN Programming
Why is providing your VIN so critical? Your GM truck isn’t just a single machine; it’s a network of computers. The TCCM needs to speak the exact same language as your Engine Control Module (ECM) and Body Control Module (BCM). By programming the GM Transfer Case Control Module 24239190 to your VIN, we ensure it knows precisely which transfer case you have (e.g., RPO code NQH or NQF), your axle ratios, and other critical parameters. This prevents communication conflicts that can cause persistent errors or even damage to drivetrain components. This isn’t just a convenienceโit’s the key to a correct and lasting repair.
Don’t let a small electronic part sideline your powerful and capable truck. This is your opportunity to fix it right the first time. By ordering this pre-programmed GM Transfer Case Control Module 24239190, you’re not just buying a part; you’re buying a solution that restores your vehicle’s function and your confidence as a driver. Get your truck back to 100% and be ready for anything the road throws at you.

Why do you need my VIN to sell me this part?
Your vehicle’s Vehicle Identification Number (VIN) allows us to program the module with the exact software and calibrations specified by GM for your truck’s unique configuration, including its engine, transmission, and specific transfer case model. This ensures seamless integration and perfect operation right out of the box.
Is this module difficult to install?
No, this is a straightforward installation for a DIYer with basic tools. The TCCM is typically located under the driver’s side of the dashboard. Since we handle all the programming, the physical replacement is a simple plug-and-play process. No special computer or dealer visit is required after installation.
Will this definitely fix my “Service 4WD” light?
While a faulty TCCM is the most common cause for the “Service 4WD” light and related symptoms on these vehicles, it’s important to properly diagnose the issue.
