How to Reset the Computer on a 1992 Cadillac

You can reset the computer on your 1992 Cadillac right from your home garage, saving yourself time and money. The Cadillac comes equipped with an on-board diagnostics (OBD) computer that receives and stores trouble codes sent from various sensors positioned throughout the vehicle. It alerts you to any malfunctions or servicing needs by illuminating a warning or service light on the instrument panel. After you have read the codes and had the vehicle repaired or serviced, you or your mechanic must reset the computer to ensure that it continues to function properly.

Instructions

    1

    Locate the rectangular fuse panel cover on the lower part of the driver side of the dashboard. Pull down on it with your fingers to open it.

    2

    Insert the key into the ignition, and turn it to the "On" position. Dont crank the engine.

    3

    Find the port inside the fuse panel that has the exact same size and shape as the connector end of the OBD scanner. Plug the OBD scanner into this port. Dont force it in; rotate the scanner until it fits into the port.

    4

    Wait for the OBD scanner to read the codes. Find the command on the scanner that reads "Delete Codes" or a similar command. Select this command to clear the codes and reset the computer. When the scanner has returned to the main menu, unplug the scanner and close up the fuse panel cover. Turn off the vehicle.

    Turn on the engine and verify that the warning and service lights are off, indicating that you have reset the computer and cleared the codes.
