-
A fuel temperature at the second ignition switch ON is −5°C (23°F) or more and less than 35°C (95°F).
-
The temperature difference between engine coolant and fuel is 5°C (41°F) or more.
NOTE:
This self-diagnosis is not performed if the distance traveled is extremely short.
-
Turn ignition switch ON.
