Expert Insight: The Critical Role of Correct Programming
As a technician with over two decades of experience, I’ve seen countless vehicle owners chase expensive sensor and component replacements, only to find the root cause was the PCM all along. Grabbing a used module from a salvage yard might seem like a cheap fix, but it’s a huge gamble.

We don’t just sell you a part; we provide a fully integrated solution by matching the Programmed 2001-2002 Suburban 2500 PCM specifically to your vehicle’s DNA, ensuring a lasting and reliable repair.
Frequently Asked Questions
Where do I provide my vehicle’s VIN?
You can enter your 17-digit VIN in the notes section during checkout. If you miss it, don’t worry! We will contact you via email after your purchase to request the information before we program and ship your module.
Do I need to do anything after installing the PCM?
Yes. While the module is programmed for your engine and transmission, you will need to perform a security relearn procedure so it recognizes your specific keys. This process, often called a CASE relearn, typically takes about 30 minutes and can be done without any special tools. We can provide instructions for this simple procedure.
Is this a brand new part?
This is a high-quality, genuine GM original equipment part that has undergone rigorous testing to ensure it meets or exceeds factory specifications. We stand by its reliability and performance, providing you with a dependable, long-term solution.
How do I know for sure my old PCM is bad?
While the symptoms listed above are strong indicators, a definitive diagnosis often involves checking for specific trouble codes (like P0601 – Internal Control Module Memory Check Sum Error) and ensuring all power and ground circuits to the PCM are intact. If other potential causes have been ruled out, the PCM is the most likely culprit.
Will this fit other GM trucks besides the Suburban 2500?
Yes, this PCM with service number 12200411 is compatible with a very wide range of 2001-2002 GM trucks, vans, and SUVs, including the Silverado, Sierra, Tahoe, Yukon, and Express/Savana vans. Our VIN programming process ensures it will function correctly for any compatible vehicle.
