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) Connect scan tool to DLC with ig nition switch OFF, if available.
2) Clear DTC in TCM memory and start engine.
3) Shift select lever to “D” range and drive vehicle at 50 km /h (31 mile/h) or more with 3rd gear at least for 5 minutes.
4) Stop vehicle and check DTC.

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.

3 Inspect input shaft speed sensor
1) Inspect input shaft speed sensor referring to “Input Shaft
Speed Sensor Inspection”.
Is result satisfactory? “WHT” or “BLK” circuit
open or short.
