      Standard Resistance

      Tester Connection Condition Specified Condition
      1 - 2 20°C (68°F) 5.0 to 5.6 Ω
      TEXT IN ILLUSTRATION

      *a Component without harness connected
      (Shift Solenoid Valve SL1)
    2. Connect the positive (+) lead with a 21 W bulb to terminal 2 and the negative (-) lead to terminal 1 of the shift solenoid valve SL1 connector, then check the movement of the valve.

      OK

      The solenoid makes an operating sound.

      If the result is not as specified, replace the shift solenoid valve SL1.

  2. INSPECT SHIFT SOLENOID VALVE SL2 

    HINT: 

    Refer to the procedures for the shift solenoid valve SL1.

  3. INSPECT SHIFT SOLENOID VALVE SL3 

    HINT: 

    Refer to the procedures for the shift solenoid valve SL1.

  4. INSPECT SHIFT SOLENOID VALVE SL4 

    HINT: 

    Refer to the procedures for the shift solenoid valve SL1.

  5. INSPECT SHIFT SOLENOID VALVE SL5 

    HINT: 

    Refer to the procedures for the shift solenoid valve SL1.

  6. INSPECT SHIFT SOLENOID VALVE SLU 

    HINT: 

    Refer to the procedures for the shift solenoid valve SL1.

  7. INSPECT SHIFT SOLENOID VALVE SLT 

    HINT: 

    Refer to the procedures for the shift solenoid valve SL1.

  8. INSPECT SHIFT SOLENOID VALVE SC1 
    1. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      Shift solenoid valve SC1 connector terminal - Shift solenoid valve SC1 body 15 to 25°C (59 to 77°F) 11 to 15 Ω
      TEXT IN ILLUSTRATION

      *a Component without harness connected
      (Shift Solenoid Valve SC1)
    2. Connect the positive (+) lead to the terminal of the shift solenoid valve SC1 connector, and the negative (-) lead to the shift solenoid valve SC1 body.

      OK

      The solenoid makes an operating sound.

      If the result is not as specified, replace the shift solenoid valve SC1.

  9. INSPECT SHIFT SOLENOID VALVE SC2 

    HINT: 

    Refer to the procedures for the shift solenoid valve SC1.
