Expert Insight: Why VIN Programming is Non-Negotiable
On these late-90s GM vehicles, the PCM is more than just an engine controller; it’s deeply integrated with the vehicle’s anti-theft system (VATS/Passlock) and transmission settings. Simply swapping a module from another car won’t work and will likely result in a no-start condition. Our VIN-specific programming ensures that the module we send you is a perfect electronic match for your car’s unique configuration. We load your VIN, which tells the PCM everything it needs to know about your engine, transmission, and security system. This critical step is what makes our solution a true plug-and-drive fix, saving you time, money, and the headache of a failed repair.
Don’t let a faulty computer keep your reliable car off the road. This is your opportunity to get a dependable, correctly prepared part that solves the problem correctly the first time. By purchasing a properly flashed 1998 Oldsmobile Achieva PCM 09356741, you are making a smart investment in your vehicle’s longevity and your own peace of mind.
Frequently Asked Questions
Do I need to do any programming myself?
No. The main benefit of our service is that we program the module for you before it ships. All you need to do is provide us with your vehicle’s 17-digit VIN during or after checkout, and we handle the rest.
What information do you need from me?
We only need your complete and accurate Vehicle Identification Number (VIN). This is essential for us to load the correct GM software and ensure compatibility with your specific vehicle.
Where can I find my VIN?
Your VIN can be found on a metal tag on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, and on your vehicle’s registration and insurance documents.
Is this part difficult to install?
For most individuals with basic mechanical skills, this is a straightforward installation. The PCM is typically located in the engine bay or under the dashboard. It involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and then installing the new one in the reverse order.

My original part number isn’t 09356741, but my car is on the list. Will this work?

If your number is on that list, this module is the correct replacement.
