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.

5 Check output shaft speed sensor signal circuit for open
1) Check continuity between “PPL” wire terminal of
disconnected output shaft speed sensor harness side
connector and terminal “C35-25” of disconnected
harness side TCM connector.
Is continuity indicated? Go to Step 6. “PPL” wire open.
6 Inspect output shaft speed sensor
1) Inspect output shaft speed sensor referring to “Output
Shaft Speed Sensor Inspection”.
Is check result satisfactory? Go to Step 7. Replace output shaft
speed sensor.
7 Check output shaft speed sensor gears visually
1) Check output shaft speed sensor gears for the
followings.
