4. Fuel Trim Monitor Drive Cycle Pattern

Test Conditions And Procedures
1. Perform a road test in a state where all of the following conditions are satisfied.
(1) Engine coolant temperature: 80-97°C (176-207°F) (Engine warm-up completed)
(2) Atmospheric temperature: -10°C (14°F) or higher or 60°C (140°F) or lower
(3) ATX conditions:
- Selector lever position: D range
- Overdrive switch: ON
- Power/economy changeover switch: Power
2. One trip monitoring is completed by making a trip in the following pattern (from when the engine is started to when the ignition switch is placed in the OFF position). (Required time approx. 35 minutes)
*1:After the engine has completely warmed up, set the ignition switch to OFF.
*2: Start the engine and quickly accelerate it until the vehicle speed reaches any speed between 89 and 97 km/h (55 and 60 mph).
3: Monitoring in progress. While maintaining the vehicle speed within a range from 89 to 97 km/h (55 to 60 mph), continue to travel for more than 30 minutes. During the period, don't drive at a constant speed for more than 120 seconds. (Slightly accelerate in less than 120 seconds. You may depress the brake pedal, but avoid abrupt brake application.)
*4: Decelerate the engine and stop the vehicle. After the vehicle has come to a stop, set the ignition switch to OFF.
