Expert Insight: The Critical Role of VIN Programming
For these 90s GM vehicles, VIN-specific programming isn’t just a convenience—it’s essential. Many of these cars are equipped with a Passlock or VATS anti-theft system that is directly tied to the PCM. A generic, unprogrammed module will prevent the car from starting, even if it’s the correct part number. By flashing the module with your exact VIN, we ensure the anti-theft system recognizes the new computer, the transmission shifts correctly, and all engine parameters are perfectly matched to your vehicle’s original specifications. This is the key to a successful and stress-free repair.
Frequently Asked Questions
Do I need to do any programming or flashing myself?
Absolutely not. This module is completely plug-and-play. We handle all the programming before it ships. All you need to do is disconnect the battery, swap the old module with this one, and reconnect the battery.
Where do I provide my vehicle’s VIN?
After you complete your purchase, we will send you an email requesting your VIN. You can also add your VIN to the notes section during checkout. We cannot ship your order until we have this information.
How do I know if this is the right part for my car?
This unit is a direct replacement for part numbers 16218070 and 16217058. Please check the fitment list on this page and, if possible, match the part number from your original module to ensure perfect compatibility.
What tools are required for installation?
Installation is simple and typically only requires basic hand tools, such as a socket set (commonly 7mm or 10mm sockets) to remove the module’s mounting bolts and electrical connectors.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original PCM (common codes include P0601-P0606), then this replacement module will solve the problem. It is always recommended to resolve any other mechanical or sensor-related issues first.
What does the warranty cover?
The one-year replacement warranty covers the module itself. If the unit fails within one year of the purchase date, we will provide a direct replacement.
