AUTOMATIC TRANSMISSION SYSTEM Shift Paddle Switch Circuit

DESCRIPTION

When the shift lever is in M, the shift range can be changed using the shift paddle switches. It is also possible to select the shift range when the vehicle is being driven with the shift lever in D by operating the shift paddle switches.

      Front view of wire harness connector

      (to Spiral Cable Sub-assembly)

      Disconnect the spiral cable connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      L110-2 (ECC) - Body ground Always Below 1 Ω

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  2. INSPECT SPIRAL CABLE SUB-ASSEMBLY


    1. Remove the spiral cable sub-assembly Click here.

      A001D3KE02

    2. Set the spiral cable to the center position.

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


      1. After setting the spiral cable to the center position, rotate the spiral cable 2.5 times clockwise and measure the resistance. Then rotate the spiral cable 2.5 times counterclockwise and measure the resistance.

      2. After setting the spiral cable to the center position, rotate the spiral cable 2.5 times clockwise. Then while rotating the spiral cable 5 times counterclockwise, measure the resistance.

        Standard Resistance
        Tester Connection Condition Specified Condition
        z15-10 (SUP) - L110-5 (SUP) Always Below 1 Ω
        z15-4 (SDN) - L110-12 (SDN) Always Below 1 Ω
        z15-7 (ECC) - L110-2 (ECC) Always Below 1 Ω

        Note

        As the spiral cable may break, do not rotate the spiral cable more than the specified amount.
