  1. When the fuel fill cap caution is displayed by the first drive cycle leak judgment (Pending DTC stored) at a 0.02 inch leak or a 0.09 inch leak, the fuel fill cap caution goes out when the next failure occurs (second drive cycle) and P0455 or P0456 is stored. (MIL illuminates)
  2. When no leak is judged by a 0.02 inch leak or a 0.09 inch leak after the fuel fill cap caution is displayed, the fuel fill cap caution goes out when the ignition switch is turned to ON (II) the next time.
  3. When driven three times without this failure detected and a 0.02 inch leak or a 0.09 inch leak detection is not done after the fuel fill cap caution is displayed, the fuel fill cap caution goes out.
