An Expert’s Note on VIN Programming
As a technician, I’ve seen countless vehicle owners try to save a few dollars by installing a used, non-programmed computer from a salvage yard. This almost always leads to more problems. Your vehicle’s PCM is not a generic part; it’s the central command center that needs to know every specific detail of your van, from the engine size to the axle ratio. Our VIN programming service isn’t just about making it workโit’s about making it work correctly. We install the latest GM calibrations, which often include fixes for issues the vehicle had when it was new. This ensures optimal performance and prevents the frustrating, hard-to-diagnose problems that come with an incorrect module.
Frequently Asked Questions
Is this module difficult to install?
Installation is straightforward for anyone with basic mechanical skills. It typically involves disconnecting the battery, unplugging the electrical connectors from the old PCM, unbolting it, and then installing the new one in reverse order. The only additional step is a simple security relearn procedure, which can be done without special tools and takes about 30 minutes.
Where do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a note during checkout or reply to your order confirmation email. We cannot program and ship your 2001-2002 Express 3500 PCM 12576160 without it.
Does this PCM require any additional programming at the dealer?
No. This module comes fully programmed to your vehicle’s VIN. The only procedure required after installation is the security relearn (also known as the anti-theft relearn), which pairs the new computer to your vehicle’s ignition system.
What happens if I don’t perform the security relearn?
If the security relearn is not performed, the vehicle’s anti-theft system will prevent the engine from starting. The engine will typically crank but not fire up, or it may start and immediately stall. This is a normal security feature.
