Expert Insight: Why VIN-Specific Flashing is Non-Negotiable
In modern vehicles, the PCM is more than just an engine controller; it’s integrated with the anti-theft system (like GM’s Passlock/VATS). Simply swapping a module from another vehicle won’t work โ your car won’t start. Our VIN programming service correctly configures the PCM to communicate with your specific vehicle’s security system and other modules. This crucial step ensures a true plug-and-drive installation, saving you the headache and expense of towing your vehicle to a dealer just for programming.
Frequently Asked Questions
Do I need to do any programming myself?
Absolutely not. This PCM will arrive at your door fully programmed to the VIN you provide during checkout. All you need to do is install it. This is a true plug-and-drive solution.
How do I provide my vehicle’s VIN?
After you complete your purchase, we will contact you for your VIN. You can also add your vehicle’s 17-digit VIN in the ‘notes’ section during the checkout process to expedite your order.
Is this the correct part for my car?
This module is compatible with a wide range of 1998-1999 GM vehicles. Please review the detailed compatibility list on this page and, most importantly, confirm that one of the listed service numbers (e.g., 16236757, 09356741) matches the one on your current module.
Will this fix my check engine light?
If the check engine light and associated codes are caused by a faulty PCM, this part is the correct solution. However, we always recommend ensuring that other components, such as wiring and sensors, are in good working order, as a faulty sensor can sometimes mimic PCM failure.
What does the warranty cover?
This unit is backed by our one-year replacement warranty. This covers the module itself against any functional defects for a full year from the date of purchase.
