1. A vehicle traveling state recording method comprising:
- recording information on traveling states, the information including traveling speeds of a vehicle, in a memory built in a computer, the computer controlling an engine and an amount of fuel supply;
stopping the recording of the information on the traveling states when the vehicle stops;
reading the recorded information out from the memory;
outputting the read-out information from an output terminal;
changing a connection state of a predetermined terminal of the computer for engine control to perform a predetermined operation; and
displaying the recorded traveling speed on a speed meter of the vehicle.

Abstract
Information indicating traveling states such as a traveling speed SPD is recorded in a computer for engine control. The recorded information can be read out using a self-diagnostic function after stopping of a vehicle. By a simple operation of grounding a certain terminal, it can also be displayed simply by blinking of a CE lamp. Since the record with high reliability remains, use can be made as materials on fair regulation.
