4. GENERAL DRIVING CYCLE
0.04-inch Diagnosis
• Perform the diagnosis only once in 335 seconds or more after starting the engine, at a constant speed of
32 km/h (19.9 MPH) or more.
• Pay attention to the fuel temperature and fuel level.
0.02-inch Diagnosis
• Perform the diagnosis 120 seconds or more after starting the engine at a constant engine speed of 30 km/
h (18.64 MPH) or higher to judge as NG or OK.
• If judgment cannot be made, repeat the diagnosis.
• Be careful of the remaining fuel level.
