How do you reset the computer on an 1997 Mitsubishi mirage de 1.5?

To reset the computer on a 1997 Mitsubishi Mirage DE 1.5, you can disconnect the negative battery cable for about 10-15 minutes. This will clear the stored codes and reset the engine control unit (ECU). After reconnecting the cable, start the vehicle and allow it to idle for a few minutes to let the ECU relearn its parameters. Ensure you have any necessary radio codes or settings saved, as this process may reset them as well.
