DTC Confirmation Procedure
WARNING:
- When performing a road test, select a place where there is no traffic or possibility of a traffic accident and be very careful during testing to avoid occurrence of an accident.
- Road test should be carried out with 2 persons, a driver and a tester, on a level road.
NOTE:
Check to make sure that the following conditions are satisfied when using this "DTC Confirmation Procedure".
- Intake air temp.: -8 °C (18 °F) or higher
- Engine coolant temp.: 74 - 110 °C (165 - 230 °F)
- Altitude (barometric pressure): 2400 m, 8000 ft or less (560 mmHg (75 kPa) or more)
- Connect scan tool to DLC with ignition switch turned OFF.
- Turn ON ignition switch and clear DTC, pending DTC and freeze frame data by using scan tool.
- Increase vehicle speed to 80 - 90 km/h (50 - 56 mph).
- Keep above vehicle speed for 5 min. or more (Throttle valve opening is kept constant in this step).
- Stop vehicle and check if pending DTC exists by using scan tool. If not, check if catalyst monitoring test has completed by using scan tool. If not in both of above checks (i.e., no pending DTC and catalyst monitoring test not completed), check vehicle condition (environmental) and repeat Steps 3 through 5).
