Caution / Notice / Hint
- Perform the universal trip to clear permanent DTCs.
Refer to DTC CHECK / CLEAR [11/2017 - ]
- Perform registration and/or initialization when parts related to the automatic transmission are replaced.
Refer to PRECAUTION [10/2018 - 10/2022]
- ACTIVE TEST
HINT:
Using the Techstream to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.
- Warm up the engine.
- Turn the engine switch off.
- Connect the Techstream to the DLC3.
- Turn the engine switch on (IG).
- Turn the Techstream on.
- Enter the following menus: Powertrain / Transmission / Active Test.
HINT:
While driving, the shift position can be forcibly changed with the Techstream. Comparing the shift position commanded by the Active Test with the actual shift position enables you to confirm the problem.
Refer to FAIL-SAFE CHART [11/2017 - ]
- According to the display on the Techstream, perform the "Active Test".

- This test can be conducted when the vehicle speed is 50 km/h (31 mph) or less.
- The 4th to 5th and 5th to 6th up-shifts must be performed with the accelerator pedal released.
- The 6th to 5th and 5th to 4th down-shifts must be performed with the accelerator pedal released.
- Do not operate the accelerator pedal for at least 2 seconds after shifting and do not shift successively.
- The shift position commanded by the ECM is shown in the Data List (Shift Status) display on the Techstream.
- The shift solenoid valve S1 is turned on/off normally with the shift lever in D:
