An Expert’s Note: The Critical Role of VIN Programming
As a technician, I’ve seen countless vehicle owners try to save a few dollars by installing a used PCM from a salvage yard. The result is almost always the same: a no-start condition, persistent error codes, and immense frustration.

Our process of programming this 2003 GMC Yukon XL 2500 PCM to your specific VIN isn’t just a featureโit’s the only way to guarantee a successful and lasting repair. We ensure the digital handshake between the module and your vehicle is perfect, saving you time, money, and the headache of a failed repair.
Frequently Asked Questions
Is this module ready to install when I receive it?
Yes, the module arrives fully programmed to the VIN you provide. After installation, you will likely need to perform a simple security relearn procedure (often called a Passlock or VATS relearn), which can typically be done without special tools. Instructions are widely available online for your specific model.
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 the module until we receive this information, as the programming is essential for the part to function in your vehicle.
Will this fix my specific error codes?
This PCM is a common solution for internal module fault codes like P0601 (Internal Control Module Memory Check Sum Error) and other P06xx codes. While it can resolve many issues, it’s always best to have a proper diagnosis to confirm the PCM is the source of the problem before ordering.
