Frequently Asked Questions
Do I need to get this computer programmed?
No. The main benefit of our service is that we program the module for you before it ships. You just need to provide us with your vehicle’s VIN during or after checkout. It will be ready to install right out of the box.
What information do you need from me?
We only need your 17-digit Vehicle Identification Number (VIN). This allows us to flash the computer with the exact software and calibrations your specific vehicle requires.
Is this a difficult part to install?
For most of the compatible GM models, the PCM is in an accessible location and installation is a straightforward, plug-and-play process. It typically involves disconnecting the battery, unplugging the electrical connectors from the old unit, unbolting it, and then installing the new one in the reverse order. Basic hand tools are usually all that is required.
Will this fix my check engine light?
If your check engine light and performance issues are directly caused by a faulty internal processor or software corruption in your old PCM (indicated by codes like P0601-P0606), then this part is the correct solution. It’s always best to have the codes properly diagnosed to confirm the PCM is the point of failure.
How does the one-year replacement warranty work?
If the module fails within one year of the purchase date, we will provide a direct replacement unit. This 1998 Buick Century PCM replacement is built to provide long-lasting reliability, and our warranty backs that up.
