An Expert’s Note on Programming
For these early 2000s GM vehicles, the PCM is the absolute brain of the operation. It doesn’t just manage the engine; it’s deeply integrated with the transmission, ABS, and the anti-theft system (VATS/Passlock). Simply installing a used, un-programmed module will result in a no-start condition every time. Our process of programming the 2003 Yukon XL 2500 PCM to your specific VIN ensures all these systems communicate correctly from the moment you turn the key, which is the secret to a successful and lasting repair.
This module is a direct replacement for multiple service numbers, including 12581565, 12570557, 12576106, and 89017733. By providing your VIN upon purchase, you guarantee you receive a perfectly matched and updated computer for your specific vehicle configuration. Don’t let a bad computer keep your reliable GM truck off the road. This is the solution that gets the job done right.
Frequently Asked Questions
Do I need to do any programming after I receive it?
No. We handle all the programming to your vehicle’s VIN before shipping. The only thing you will need to do is a simple security relearn procedure, which can be done without any special tools and typically takes 10-30 minutes. We can provide instructions for this process.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information.
What is the security relearn procedure?
It’s a simple process that syncs the new PCM with your vehicle’s anti-theft system. It typically involves turning the key to the ‘ON’ position for 10 minutes, then ‘OFF’ for 10 seconds, and repeating this sequence three times. This allows the vehicle to recognize the new, correctly programmed module.
Is this compatible with other vehicles besides the Yukon XL 2500?
Yes, this PCM is compatible with a wide range of 2003-2004 GM trucks, vans, and even some cars that use this hardware. Please check the detailed compatibility list in our description to confirm it fits your specific make, model, and engine size.
What if my original PCM has a different service number?
That’s perfectly fine. GM uses many different service numbers for the same computer hardware. As long as your original service number is on our compatibility list (e.g., 12581565, 12576106, etc.), this unit will be a correct replacement once we program it to your VIN.
