An Expert’s Note on GM Anti-Theft (VATS)
As a technician who’s worked on countless 90s GM trucks, I can tell you that just grabbing a used computer from a salvage yard rarely works. These vehicles use a Vehicle Anti-Theft System (VATS) or Passlock system that’s tied to the original vehicle’s VIN. Installing an un-programmed module will result in a no-start condition every time. Our service is the critical step that makes this repair possible for the DIYer or independent shop. By programming the Programmed 9355699 PCM to your VIN beforehand, we handle the complex part, so you can focus on the simple installation.
Frequently Asked Questions
How does the programming process work?
After you place your order, you must provide us with your vehicle’s 17-digit VIN. Our technicians use this number to access the official GM database and load the exact software and calibrations your vehicle requires onto the PCM before it ships.
Will I need to do anything after installation?
In some vehicles, a simple security relearn procedure may be required after installation. This procedure is straightforward, takes about 30 minutes, and can be done without any special tools. We can provide instructions for this if needed.
Is this a new or used part?
This is a high-quality, used OEM computer sourced from a salvaged vehicle. Each unit is thoroughly inspected and tested before being programmed and shipped to ensure it is fully functional and reliable.
How do I find my part number?
Your original PCM will have a sticker on it with the service number. This unit, ID 9355699, directly replaces several part numbers including 16250279, 16266645, and more. As long as your vehicle is on the compatibility list, this programmed unit will work.
What is the difference between a PCM, ECU, and ECM?
The terms are often used interchangeably. ECM (Engine Control Module) typically only controls the engine. ECU (Electronic Control Unit) is a generic term. A PCM (Powertrain Control Module), like this one, is the most accurate term as it controls both the engine and the transmission functions.
What happens if I provide the wrong VIN?
Providing the correct VIN is critical. An incorrect VIN will result in the wrong software being loaded, and the part will not work in your vehicle. Please double-check your VIN from your driver’s side door jamb sticker or dashboard plate before sending it to us.
