Expert Insight: The Critical Role of VIN Programming
Many people buy used engine computers online hoping for a cheap fix, only to find their truck won’t start after installation. This is often due to the GM Vehicle Anti-Theft System (VATS/Passlock). Because our modules are programmed to your specific VIN before they ship, they are properly prepared to communicate with your truck’s security system. This crucial step makes the final installation process much smoother, often only requiring a simple security relearn procedure that you can do yourself, saving you hundreds in diagnostic and programming fees.
Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We must have your VIN to program the module before we can ship your order.
Will I need to do anything after installing the PCM?
Yes. After installation, you will need to perform a security relearn procedure, also known as a VATS relearn. This process syncs the new PCM with your vehicle’s anti-theft system. It’s a simple procedure that typically takes 30-40 minutes and does not require any special tools.
Is this a brand new part?
This is a high-quality, OEM-grade replacement component that has been thoroughly inspected and verified to meet or exceed original factory performance standards. It is programmed with the latest software for your vehicle.
My original part number is different. Will this still work?
Yes. This module is a direct replacement for several service numbers, including 89017750, 12582605, 12589463, 12602802, and more. As long as your vehicle is listed in the compatibility chart, we will program the module to function perfectly for your specific make, model, and year.
Will this 2003-2007 Hummer H2 PCM 89017750 fix my specific problem?
While this PCM is the solution for a wide range of electronic and drivability issues, proper vehicle diagnosis is always recommended. This part will correct problems directly caused by a failing computer, but it will not fix underlying mechanical or wiring issues.
