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

(a) Connect Techstream to the DLC3.

(b) Turn the ignition switch on (IG) and turn Techstream on.

(c) Enter the following items: "Powertrain / ECT / Active Test".

HINT

Comparing the shift position commanded by the Active Test with the actual shift position enables confirmation of the problem

See: Powertrain Management/Transmission Control Systems/Testing and Inspection/Initial Inspection and Diagnostic

Overview/Fail-Safe Chart.

NOTICE:

* This test can be conducted when the vehicle is stopped.

* When shifting gears using the Active Test function, do not operate the accelerator pedal for 2 seconds before and after shifting

gears.

HINT

The shift position commanded by the TCM is shown in the Data List/Shift Status display on Techstream.

(d) Check the vehicle speed and the gear position when the engine speed is 1,000 rpm.

HINT

Because the torque converter clutch has not engaged, it may be difficult to obtain the speeds specified in 4th, 5th, and 6th gear,

however a difference of speed should still be evident following each gear change.
