As a technician with over two decades of experience, I’ve seen countless vehicle owners waste time and money on modules bought from a salvage yard or a seller that doesn’t program them. For these late-90s GM vehicles, the PCM is the central hub. A module that isn’t programmed to your specific VIN can cause a host of new problems, from anti-theft system lockouts to incorrect transmission behavior. Our process of programming the module before it ships is the critical step that guarantees a successful, hassle-free repair and makes this the correct choice for your 1999 GMC Yukon PCM replacement.

Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM) is your vehicle’s main computer. It controls all aspects of engine and transmission function, including fuel-to-air ratio, ignition timing, and transmission shift points, to ensure optimal performance, efficiency, and emissions.
Do I need to do anything after installation?
No. Because we program the module to your VIN before shipping, it is a true plug-and-play part. In some cases, a Crankshaft Variation Relearn procedure may be needed, which can be done with a capable scan tool or by a local mechanic, but often the vehicle will run perfectly upon installation.
Where can I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a metal plate on the driver’s side dashboard visible through the windshield. It is also typically on a sticker on the driver’s side door jamb.
How do I know for sure that my PCM is failing?
While the symptoms listed above are strong indicators, the best way to be certain is through professional diagnosis. However, if you have ruled out other common causes like sensors, wiring, and fuel delivery, and the issues are intermittent and electronic in nature, the PCM is the most likely culprit.
Is this compatible with other part numbers?
Yes, this module is a direct replacement for several part numbers, including 16250279, 09366810, and 09355699. Please check the fitment list to confirm it matches your specific make, model, and year.
What happens after I place my order?
After you complete your purchase, you must provide us with your vehicle’s VIN. We cannot ship the module until we have this information. Once we receive your VIN, we will program the module with the latest GM software and ship it to you, ready for installation.
