Frequently Asked Questions
What exactly does the PCM do?
The Powertrain Control Module, or PCM, is the central computer of your vehicle. It controls critical functions of the engine and transmission, such as fuel injection, spark timing, and transmission shift points, to ensure optimal performance, fuel efficiency, and emissions control.
Is this part difficult to install?
For most 1998 GM models, the PCM is located in an accessible spot, often in the engine bay or under the dashboard. Installation typically involves disconnecting the battery, unplugging the electrical connectors from the old unit, unbolting it, and then installing the new one in reverse order. Because our module is pre-programmed, no further computer setup is needed, making it a straightforward job for a DIYer with basic tools.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically find this on your vehicle’s registration, insurance card, or on a plate on the driver’s side of the dashboard visible through the windshield. We cannot ship your part until we receive your VIN.
