An Expert’s Note on VIN Programming
As a technician with over two decades of experience, I’ve seen countless vehicle owners waste time and money on used computers from salvage yards. Those units are not programmed for your specific vehicle. They won’t account for your engine, transmission, or factory options, leading to a cascade of new problems. Our process of programming this 2004 Yukon XL 2500 PCM 12586242 to your exact VIN is the single most critical step in ensuring a successful repair. It means the computer knows your vehicle inside and out from the moment you turn the key, just like it did the day it left the factory.
Frequently Asked Questions
Do I need to do anything after installing this PCM?
In most cases, you will need to perform a security relearn procedure, also known as a Passlock or anti-theft relearn. This procedure is straightforward and can typically be done without special tools. Instructions are readily available online for your specific model. Some vehicles may also require a Crankshaft Position Sensor (CASE) relearn, which requires a capable scan tool.
How do I provide my VIN?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN (Vehicle Identification Number). We will provide clear instructions on how to do this. We cannot ship your part until we receive and validate your VIN, as this is essential for the programming process.
How can I be sure this is the right part?
The best way to confirm compatibility is to check the service number on your current computer. This unit replaces service number 12586242 and many others listed in the description. If your number matches one on our list, this is the correct part for you.
What makes this better than a used computer from a junkyard?
A used computer is programmed for the vehicle it came from, not yours. Our PCM is cleaned, inspected, and most importantly, flashed with the latest GM software specifically for your vehicle’s VIN. This ensures correct operation of all systems and avoids the compatibility headaches common with used modules.
What if my original part number is not on the list?
If your part number is not listed, this module may not be the correct one for your vehicle. Please contact us with your original part number and VIN, and our team of experts will be happy to help you find the exact part you need.
