PROCEDURE


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


    1. Disconnect the F78 ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      F78-1 (SLT+) - F78-31 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω
      F78-1 (SLT+) or F78-31 (SLT-) - Body ground Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG

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


    1. Disconnect the F73 transmission wire connector.

    2. Disconnect the F78 ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      F73-22 (SLT+) - F78-1 (SLT+) Always Below 1 Ω
      F73-23 (SLT-) - F78-31 (SLT-) Always Below 1 Ω
      F73-22 (SLT+) or F78-1 (SLT+) - Body ground Always 10 kΩ or higher
      F73-23 (SLT-) or F78-31 (SLT-) - Body ground Always 10 kΩ or higher
      Result
      Proceed to
      OK

    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 (SLT) 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 an operating sound.
