AUTOMATIC TRANSMISSION SYSTEM Shift Paddle Switch Circuit

DESCRIPTION

When the shift lever is in M, it is possible to change into any gear using the steering assembly transmission shift switch.

Additionally, when the vehicle is being driving with the shift lever in D, operating the steering assembly transmission shift switch changes to selection of gears with the shift lever in D, enabling shifting to any gear.

PROCEDURE


  1. READ VALUE USING GTS


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Read the value displayed on the GTS.

      OK
      Tester Display Condition Standard
      Sport Shift Up SW

      Continuously shift to "+" (upshift): ON

      Release "+" (up-shift): OFF

      		 -
      Sport Shift Down SW

      Continuously shift to "-" (down-shift): ON

      Release "-" (down-shift): OFF

      		 -

  2. CHECK HARNESS AND CONNECTOR (TRANSMISSION SHIFT SWITCH - TCM)


    1. Disconnect the TCM connector.

    2. Measure the resistance according to the value(s) in the table below.

      Standard resistance
      Tester Connection Condition Specified Condition
      A19-1(SFTD) - Body ground

      Pull continuously

      "+"

      (Up shift)

      		 Below 1 Ω
      Release "+" or "-" 10 kΩ or higher
      A19-2(SFTU) - Body ground

      Pull continuously

      "-"

      (Down shift)

      		 Below 1 Ω
      Release "+" or "-" 10 kΩ or higher

    3. Connect the TCM connector.
