Expert Insight: The Brains Behind the Brawn
In these late-90s GM Vortec engines, the PCM is more than just an engine controller—it’s the central command center. It precisely manages everything from the air/fuel mixture and ignition timing to transmission shift points and torque converter lockup. When you install a generic or improperly programmed module, you might solve a no-start issue but create new problems like poor shifting or reduced fuel efficiency. That’s why our VIN-specific programming is so crucial. We ensure the software loaded onto your VIN Programmed PCM 16258815 is an exact match for your vehicle’s original configuration, restoring its factory-intended operation and reliability.
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is a required step.
Is this part difficult to install?
For most vehicles this part fits, the PCM is located in the engine compartment and is held in by a few bolts with electrical connectors. Installation is typically straightforward for someone with basic mechanical skills. Disconnect the battery, unplug the old unit, swap in the new one, and reconnect the battery. That’s it!
Will I need to do anything else after installation?
In some GM vehicles of this era, a security relearn procedure (often called Passlock or Passkey) may be required. This is a simple procedure you can do yourself in about 30 minutes with just the ignition key and does not require special tools. Instructions are widely available online for your specific model.
How can I be sure this fits my vehicle?
The best way to ensure compatibility is to match the part number from your original computer to one of the numbers listed in our description (16258815, 09355699, 16266645, etc.). You can also use the detailed fitment list provided on this page to check your make, model, and year.
What does ‘used’ or ‘salvaged’ mean for this part?
This means the part is a genuine OEM computer that was carefully removed from a recycled vehicle. Each unit is inspected and tested to ensure it is fully functional before being programmed and shipped to you. This is a sustainable and reliable alternative to a brand new, expensive module.
