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.

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.: 55 - 110 °C (131 - 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 and warm up engine completely.
- Increase vehicle speed to 55 - 60 km/h (35 - 40 mph).
