Expert Insight: Why VIN Programming is Non-Negotiable
Back in the late ’90s, GM’s Vehicle Anti-Theft System (VATS) or Passlock system became standard. This security feature links your vehicle’s ignition key to the PCM. Simply swapping a computer from another truck won’t work—the engine will be disabled. That’s why our VIN programming service is essential. We don’t just load generic software; we configure the module to match your exact vehicle, ensuring it communicates correctly and allows your engine to start and run as it should. We take the guesswork out of the repair.
Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the critical programming before shipping. The only thing you will need to do after installation is a simple security relearn procedure, which syncs the computer to your vehicle’s anti-theft system. This procedure typically takes 30-40 minutes and does not require any special tools.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, simply send us a message with your 17-digit VIN. We cannot ship your order until we receive this information, as it is required for the programming process.
Is this a new part?
No, this is a high-quality, used OEM computer that has been carefully removed from a salvaged vehicle. Each unit is thoroughly inspected and tested to ensure it is fully functional before being programmed and shipped to you.
What if I install it and my truck still won’t start?
The most common reason for a no-start condition after installation is an incomplete security relearn procedure. Please ensure you follow the steps carefully. If the issue persists, it may indicate another problem with the vehicle’s wiring or other components. Our team is available to help you troubleshoot.
How can I be sure this fits my vehicle?
Please check the extensive list of compatible vehicles in this listing. The most important step is to match the part number. This 09355699 PCM replaces several numbers, including 16266645, 16250279, and more. If your original module has one of these numbers, this part will work when programmed to your VIN.
