idling
HINT:
*: Activate the Solenoid (SLT) in the Active Test is performed to check the line pressure changes by
connecting SST to the automatic transmission, which is used in the Hydraulic Test
as well. Note that
the pressure values in the Active Test and Hydraulic Test are different.
OK:
The line pressure changes as specified when performing 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.
