An Expert’s Note on VIN Programming
As a technician with over 20 years of experience, I can’t stress this enough: for these 1996 GM vehicles, VIN programming isn’t optional, it’s essential. These were some of the first vehicles with more complex OBD-II systems and anti-theft technology like VATS/Pass-Key. A module from another vehicle simply won’t workโthe car won’t start. By programming the unit to your VIN, we ensure the security handshake is correct and that the fuel delivery and transmission shift strategies match your exact vehicle configuration. This is the difference between a frustrating paperweight and a part that gets your car back to factory-spec reliability.

Do I need to have this computer programmed by a dealer?
No. We handle the programming for you before we ship the part. It will arrive ready to be installed in your vehicle. All we need is your VIN to ensure it is 100% plug-and-play.
How do I provide my vehicle’s VIN?
After you complete your purchase, you can add your 17-digit VIN to the order notes or reply to your order confirmation email. We cannot ship your part until we receive the VIN.
Is this the correct PCM for my car?
This module, part number 1996 GM PCM 16211539, fits a wide range of 1996 GM models. Please review the detailed fitment list on this page and match one of the service numbers (16211539, 88963800, 16231853) to the one on your original part to confirm compatibility.
What happens if I install it without programming?
A module that is not programmed to your specific VIN will not work. The vehicle’s anti-theft system will prevent it from starting, and it will not have the correct calibration for your engine and transmission, leading to poor performance or a no-start condition.
What tools are needed for installation?
Installation typically requires only basic hand tools, such as a socket set to remove the mounting bolts and disconnect the electrical connectors. For safety, it is crucial to disconnect the vehicle’s battery before you begin the installation process.
