Expert Insight: The Heart of a Workhorse
The late-90s GM trucks and SUVs are legendary for a reason. Their Vortec engines are simple, powerful, and built to last. But even the toughest iron relies on a healthy electronic brain. Over two decades of heat cycles and vibrations can take a toll on the original PCM’s internal components, leading to frustrating, hard-to-diagnose issues. Replacing a failing unit with a correctly programmed 16250279 PCM isn’t just a repair; it’s an investment in keeping a classic, dependable vehicle on the road for years to come. This is about restoring the factory-engineered reliability you depend on every day.
Frequently Asked Questions
What do I need to do after I place my order?
After you complete your purchase, you must send us your vehicle’s 17-digit VIN (Vehicle Identification Number). We cannot program and ship your module without it. You can typically reply to your order confirmation email with the VIN.
Is this part truly plug-and-play?
Yes. Because we program the module to your specific VIN, it will be ready to install and function correctly. However, most GM vehicles of this era require a simple security relearn procedure (often called the Passlock or VATS relearn) which involves a series of key cycles. This procedure takes about 30 minutes and can be done in your driveway without any special tools.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of your old PCM (common codes include P0601-P0606), then this replacement unit will solve the problem. If the light is on for another reason, such as a bad sensor, that issue will need to be addressed separately.
How do I find my VIN?
Your VIN can be found on a metal plate on the driver’s side of the dashboard (viewable through the windshield), on the driver’s side door jamb sticker, and on your vehicle’s registration and insurance documents.
My original part number is 09366810. Will this work?
Yes. This module is the correct hardware and is a direct replacement for part numbers 16250279, 09366810, and 09355699. Once programmed to your VIN, it will function identically.
