PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (SOLENOID (SLU) VALVE CIRCUIT)


    1. Disconnect the D1 ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      D1-3 (SLU+) - D1-2 (SLU-) 20°C (68°F) 5.0 to 5.6 Ω
      D1-3 (SLU+) - Body ground and other terminals Always 10 kΩ or higher
      D1-2 (SLU-) - Body ground and other terminals Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG

    OK

  2. CHECK HARNESS AND CONNECTOR (WIRING HARNESS CONNECTOR - ECM)


    1. Disconnect the D57 wiring harness connector connector.

    2. Disconnect the D1 ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      D57-14 (SLU+) - D1-3 (SLU+) Always Below 1 Ω
      D57-5 (SLU-) - D1-2 (SLU-) Always Below 1 Ω
      D57-14 (SLU+) or D1-3 (SLU+) - Body ground and other terminals Always 10 kΩ or higher
      D57-5 (SLU-) or D1-2 (SLU-) - Body ground and other terminals Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  3. INSPECT TRANSMISSION WIRE (SOLENOID (SLU) VALVE)


    1. A01VTI7C08
      *a

      Component without harness connected

      (Transmission Wire)

      Remove the wiring harness connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      A-11 (SLU+) - A-5 (SLU-) 20°C (68°F) 5.0 to 5.6 Ω
      A-11 (SLU+) - Body ground and other terminals Always 10 kΩ or higher
      A-5 (SLU-) - Body ground and other terminals Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG

    OK

  4. INSPECT SOLENOID (SLU) VALVE


    1. A01VVIWC14
      *1 Solenoid (SLU) Valve

      Remove the solenoid (SLU) valve.

      Click here

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 2 20°C (68°F) 5.0 to 5.6 Ω

    3. Connect a positive (+) lead with a 21 W bulb from the battery to terminal 1 and a negative (-) lead to terminal 2 of the solenoid valve connector. Check that the valve moves and makes an operating sound.

      OK
      Valve moves and makes an operating sound.
