Selecting "Clear Codes"
WARNING: This page is about a different car, the 1989 Cadillac Allante. However, it is still accessible from the selected car via links, so may be relevant.
Selection of the "CLEAR CODES" test type will result in the message "CODES CLEAR" being displayed along with the selected system name. This message will appear for 3 seconds to indicate that all stored trouble codes have been erased from that system's memory. After 3 seconds the display will automatically return to the next available test type for the selected system.
