PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE (SOLENOID (SLU) VALVE) - ECM)


    1. Disconnect the F66 ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      F66-3 (SLU+) - F66-2 (SLU-) 20°C (68°F) 5.0 to 5.6 Ω
      F66-3 (SLU+) or F66-2 (SLU-) - Body ground Always 10 kΩ or higher
      Result

  3. CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM)


    1. Disconnect the F61 transmission wire connector.

    2. Disconnect the F66 ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      F61-12 (SLU+) - F66-3 (SLU+) Always Below 1 Ω
      F61-13 (SLU-) - F66-2 (SLU-) Always Below 1 Ω
      F61-12 (SLU+) or F66-3 (SLU+) - Body ground Always 10 kΩ or higher
      F61-13 (SLU-) or F66-2 (SLU-) - Body ground Always 10 kΩ or higher
      Result

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      Terminal 1 of the solenoid (SLU) valve - terminal 2 20°C (68°F) 5.0 to 5.6 Ω

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

      OK
      Valve moves and makes operating sound.
