Exhaust Gas Recirculation (EGR) System Monitor

3. Exhaust Gas Recirculation System 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°C (176°F) or higher (Engine warm-up completed)
(2) Atmospheric temperature: 5°C (41°F) or higher
(3) ATX conditions:
- Selector lever position: D range
- Overdrive switch: ON
- Power/economy changeover switch: Power
(4) A/C switch: OFF
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. 10 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 56 and 64 km/h (35 and 40 mph).
3: Monitoring in progress. With the engine speed at 2,000 to 3,000 r/min and the clutch engaged, fully close the throttle on the (MTX) and decelerate the engine without brake application until the engine speed falls to around 900 r/min. During the period, avoid operation of the steering wheel and ON/OFF control of lights, etc.
*4: Accelerate the engine until the vehicle speed reaches any speed between 56 and 64 km/h (35 and 40 mph) and continue travel for more than 20 seconds.
[After one monitoring (deceleration), allow more than 20 seconds before starting the next monitoring (deceleration).]
Thereafter, repeat the 3 and *4 eight times.
*5: Decelerate the engine and stop the vehicle. After the vehicle has come to a stop, set the ignition switch to OFF.
