Frequently Asked Questions
Where do I provide my VIN?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is specific to your car.
Is this part difficult to install?
For someone with basic mechanical skills, the installation is straightforward. The PCM is typically located in the engine bay or under the dashboard. It involves disconnecting the battery, unplugging the old module’s electrical connectors, unbolting it, and then installing the new one in reverse order. Since this 1997-1998 Oldsmobile Achieva PCM comes pre-programmed, no special tools are needed for software setup.
Will I need to do anything after installation?
In some GM vehicles of this era, a security relearn procedure (often called a CASE relearn or Passlock relearn) may be necessary to sync the new PCM with your vehicle’s anti-theft system. This procedure can typically be done without special tools and instructions are widely available online.
How do I know my original PCM has failed?
Besides the symptoms listed above, a mechanic can confirm a failed PCM through diagnostic tests that show no communication with the module or internal processor error codes (like P0601). Physical inspection may also reveal burnt spots or corrosion on the circuit board.
