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.
1) Turn ignition switch OFF and then ON.
2) Clear DTC and warm up engine to normal operating temperature.
3) Shift selector lever to each of P, R, N, D, 2 and L ranges and hold it there for longer than 5 seconds each.
4) Check for DTC and if no DTC appears on display, proceed to the next step.
5) Drive vehicle at 40 mph, 60 km / h or more in 3rd gear of “D” range for longer than 5 sec.
