PERFORM ACTIVE TEST USING TECHSTREAM (RUNNING TEST)

CAUTION:

This test should always be performed with at least 2 people.

NOTICE:

Perform the test at the normal operating ATF temperature: 50 to 80°C (122 to 176°F).
Perform the test with the A/C turned off.

(a) Connect the Techstream to the DLC3.

(b) Clear the DTC 

 

.

(c) Warm up the engine.

(d) Enter the following menus: Powertrain / Engine and ECT / Active Test.

(e) According to the display on the Techstream, perform the Active Test.

[Vehicle Condition]

50 km/h (30 mph) or less

HINT:

This test can be conducted when the vehicle speed is 50 km/h (30 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 display on the Techstream.

(f) Compare the ECM gear shift command and the actual gear position.

OK:

Gear position changes in accordance with the Techstream command.
