4. GENERAL DRIVING CYCLE
0.04-inch Diagnosis
• Perform the diagnosis only once in 856 seconds or more after starting the engine, at a constant speed of
32 km/h (20 MPH) or more.
• Pay attention to the fuel temperature and fuel level.
0.02-inch Diagnosis
• Perform the diagnosis after 770 seconds or more after starting the engine, at a constant engine speed of
68 km/h (42 MPH) or higher, to judge as NG or OK.
• If judgment cannot be made, repeat the diagnosis.
• Be careful of the remaining fuel level.
