OBD-II Drive Cycle Procedure

OBD-II DRIVE CYCLE
A diagnostic trouble code can be monitored by carrying out a short drive in
accordance with the OBD-II drive cycle patterns. In other words, doing such a drive allows to regenerate any kind of trouble which involves illuminating the check engine/malfunction indicator lamp and to check if the repair procedure has eliminated the trouble (the check engine/malfunction indicator lamp is no more illuminated).

Evaporative Emission Control System Leak Monitor Test

Conditions and main points to note:

1. Conduct test drives in a manner that will ensure all the following conditions are met:
(1) Engine coolant temperature: 45°C (113°F) or less (the engine is stopped before the test drive is started).
(2) Atmospheric temperature: 5°C (41°F) or more, 45°C (113°F) or less.
(3) Selector lever position: D range
2. One trip monitor will be completed by driving according to the steps below (from start to ignition switch "OFF"). (Time required is approximately eight minutes.)




Drive cycle pattern

(1) Confirm that the engine coolant temperature and atmospheric temperature both satisfy the conditions given in item 1 above. (Engine stopped.)
(2) Start the engine and accelerate to 89-97 km/h (55-60mph).
(3) Monitor preparation period: Drive for 200 seconds or more while maintaining vehicle speed between 89-97 km/h (55-60 mph).
(4) Drive on a flat area for for 150 seconds or more while maintaining the vehicle speed between 89-97 km/h (55-60 mph). During this time continue driving while keeping the throttle opening angle constant (while keeping the throttle fluctuation amount as small as possible.) Monitor the scan tool display of vehicle speed and throttle opening angle in this state.
(5) Return the vehicle to the workshop, then turn the ignition OFF
