Expert Tip: The Importance of VIN Programming
Many people think you can just swap an engine computer from one truck to another. On these GM vehicles, that’s a recipe for disaster. The PCM is the ‘brain,’ and it’s tied to your specific VIN, which dictates everything from the engine and transmission calibration to the anti-theft system (Passlock/VATS). Our programming service isn’t a convenience; it’s a necessity. We ensure the programmed 9355699 PCM you receive is a true plug-and-play solution, preventing the no-start conditions and communication errors that come from using a non-programmed module.
Don’t let a bad computer keep your reliable GM vehicle down. This programmed 9355699 PCM is the key to solving those nagging electronic gremlins and restoring the dependable performance you rely on every day. Place your order, send us your VIN, and let us handle the rest.
Frequently Asked Questions
How does the programming process work?
It’s simple. After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN (Vehicle Identification Number). Our technicians then use professional tools to load the correct, updated GM software for your specific vehicle onto this PCM. We then ship the ready-to-install part to you.
Is this a new part?
No, this is a genuine, used OEM computer that has been sourced from a salvaged vehicle. Each unit is inspected to ensure it is a quality, functional part.
Will I need to do anything after installation?
In many cases, you may need to perform a security relearn procedure (often called a VATS or Passlock relearn) to sync the new computer with your vehicle’s anti-theft system. This procedure is simple, requires no special tools, and can typically be found in your owner’s manual or online.
What part numbers does this computer replace?
This unit is a direct replacement for several service numbers, including 09355699, 16266645, 16250279, 16258815, 09366810, and 9366810. Please match one of these numbers to your original module to ensure compatibility.

This unit is backed by our one-year replacement warranty, giving you confidence in your repair.
