fuel until the output voltage condition of the “FUEL LEVEL SE” meets within the range above and leave
the vehicle for more than 1 hour. Then start from step 1).
3. Turn ignition switch OFF and wait at least 10 seconds.
4. Turn ignition switch ON.
5. Select “EVAP V/S LEAK P0456” of “EVAPORATI VE SYSTEM” in “DTC WORK SUPPORT” mode with
CONSULT-III.
Follow the instruction displayed.
6. Make sure that “OK” is displayed. If “NG” is displayed, refer to EC-875, "
Diagnosis Procedure".
