AUTOMATIC TRANSMISSION SYSTEM Shift Paddle Switch Circuit

DESCRIPTION

When the shift state is in drive (D), operating the "-" side shift paddle switch will cause the transmission to enter fixed range mode which restricts the highest gear. By operating the "+" (up-shift) or "-" (down-shift) shift paddle switch, the gear can be changed.

When the vehicle is being driven with the shift state in drive (D) (fixed range mode), if the vehicle is stopped or the accelerator pedal is kept steady for a certain period of time with the transmission in the same gear, the vehicle will change back automatically to normal D position operation.

When the shift state is in manual (M), it is possible to make use of the highest engine speeds by holding the vehicle in a gear. Gear hold control means that gear shifts will not be performed as long as the "+" (up-shift), or "-" (down-shift) shift paddle switch is not operated.

PROCEDURE


  1. READ VALUE USING GTS (SPORT SHIFT UP SW AND SPORT SHIFT DOWN SW)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine / Data List.

    5. According to the display on the GTS, read the Data List.


      Powertrain > Engine > Data List
      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      Sports Shift Up SW Sport shift up switch status ON or OFF

      • ON: "+" shift paddle operated (up-shift)

      • OFF: "+" shift paddle not operated (up-shift)

      		 -
      Sports Shift Down SW Sport shift down switch status ON or OFF

      • ON: "-" shift paddle operated (down-shift)

      • OFF: "-" shift paddle not operated (down-shift)
