Toyota Tundra. Manual — part 2828



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 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.
