Is Your GM Vehicle Running Unreliably?
Dealing with a persistent check engine light, erratic shifting, or a car that just won’t start can be incredibly frustrating.

An Expert’s Note on VIN Programming
As a technician with over two decades of experience, I’ve seen countless drivers try to save a few dollars by installing a used, non-programmed computer. The result is almost always the same: a car that still won’t start, or one that runs even worse than before. That’s because the PCM is coded to the specific options and security systems of its original vehicle. Our VIN programming service isn’t just a feature; it’s the most critical step in ensuring your repair is successful. We match the software to your car’s exact specifications, making this programmed 1998 Buick Century PCM a true plug-and-drive solution that works the first time.
Frequently Asked Questions
What exactly does this PCM do?
The Powertrain Control Module (PCM), also known as the Engine Control Module (ECM), is the central computer of your vehicle. It controls all aspects of engine and transmission function, from fuel injection and spark timing to emission controls and automatic gear shifts, ensuring optimal performance and efficiency.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will need to send us a message with your 17-digit VIN. We cannot program and ship your module without it. You can typically find your VIN on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your insurance and registration documents.
Will I need to do any additional programming after installation?
No, the core engine and transmission programming is complete. However, on most GM vehicles of this era, you will need to perform a simple security relearn procedure, also known as a VATS relearn. This takes about 30 minutes and involves a sequence of key turns. We provide clear instructions to guide you through this easy process.
Where is the PCM located on a 1998 Buick Century?
On the 1998 Buick Century and many similar GM models like the Lumina and Monte Carlo, the PCM is typically located inside the air filter box housing in the engine compartment for easy access.
Is this compatible with other GM vehicles?
Yes, this module is compatible with a wide range of GM vehicles from the late 90s that use the same service number. Please check the detailed fitment list on this page to confirm compatibility with your specific make, model, and engine.
How long does the programming and shipping process take?
Once we receive your VIN, programming is typically completed within one business day. We then ship the module to you, so you can get your vehicle repaired and back on the road as quickly as possible.
