Expert Insight: Why VIN-Specific Programming is Non-Negotiable
On these late 90s and early 2000s GM vehicles, the PCM isn’t just an engine controller; it’s the central brain that manages everything from fuel delivery and spark timing to transmission shift points and anti-theft systems (Passlock/VATS). When you provide your VIN, we don’t just load a generic file. We configure the module to match your vehicle’s exact factory options. This ensures the programmed 16263494 PCM correctly recognizes your transmission type, axle ratio, and security system, preventing a host of compatibility errors and getting you back on the road without complications.
Frequently Asked Questions
What do I need to do after I place my order?
After you complete your purchase, you must send us your vehicle’s 17-digit VIN (Vehicle Identification Number). We cannot program and ship your module without it. You can typically find your VIN on your driver’s side dashboard (visible through the windshield) or on your vehicle’s registration or insurance card.
Is this module truly plug-and-play?
Yes. Because we program the module to your specific VIN, it arrives ready to be installed. In most cases, you will not need to perform any additional procedures. For vehicles equipped with a Passlock or VATS anti-theft system, a simple security relearn procedure may be necessary, which takes about 30 minutes and can be done without any special tools.
How can I be sure this is the correct part for my vehicle?
The best way to confirm compatibility is to match the part number on your existing module to 16263494 or one of the alternate part numbers listed. You can also use the comprehensive fitment list provided on this page. If you are still unsure, please contact us with your VIN and we will be happy to verify the correct part for you.
Will this fix my check engine light?
If the check engine light and associated symptoms are being caused by a faulty PCM, this part will resolve the issue. However, it’s always recommended to have your vehicle scanned for Diagnostic Trouble Codes (DTCs) to ensure the problem isn’t with a different sensor or component. This programmed 16263494 PCM is the solution when the computer itself is the root cause.
What is the warranty on this part?
This part comes with a comprehensive warranty that covers any defects in the module or its programming. We stand behind our work to give you confidence and peace of mind in your purchase. Please refer to the warranty section for specific terms and duration.
