Expert Insight: The Importance of VIN Programming
On these late-90s GM vehicles, the PCM is deeply integrated with the Vehicle Anti-Theft System (VATS) or Passlock system. Simply swapping in a computer from another truck won’t work—the vehicle will not start. Our mandatory VIN programming service correctly configures the module to your specific vehicle, ensuring it’s recognized by the security system. While you may still need to perform a simple 10-minute security relearn procedure with your key, our programming does the heavy lifting, saving you a tow to the dealer and hundreds in diagnostic fees.
Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before the part is shipped. This Programmed 9355699 PCM will arrive ready to be installed in your vehicle. In some cases, a simple security relearn procedure, which involves turning the key on and off, may be required. We can provide instructions for this easy process.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will then program the computer to match your vehicle’s exact specifications before shipping it out.
Is this a new part?
No, this is a high-quality, inspected, and tested used OEM part that was sourced from a salvaged vehicle. This allows us to provide a reliable and affordable solution.
What if my original part number is different?
This computer, ID 9355699, is a direct replacement for several other part numbers, including 16266645, 16250279, 16258815, and 09366810. Please check the fitment list on this page to confirm compatibility with your specific make and model.
Will this fix my check engine light?
If the check engine light is caused by a faulty PCM (e.g., codes P0601-P0606), then this part will solve the issue. However, it’s crucial to ensure your vehicle has been properly diagnosed, as other sensors or components could also be the cause of a check engine light.
What is the security relearn procedure?
For most GM vehicles of this era, the procedure involves turning the key to the ‘ON’ position for 10 minutes, then ‘OFF’ for 10 seconds, and repeating this cycle three times. This allows your vehicle’s security system to sync with the replacement PCM. It’s a simple process you can do in your driveway.
