PROCEDURE


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


    1. Disconnect the D2 ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      D2-76 (SLU+) - D2-61 (SLU-) 20°C (68°F) 5.0 to 5.6 Ω
      D2-76 (SLU+) or D2-61 (SLU-) - Body ground and other terminals Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG

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


    1. Disconnect the D56 transmission wire connector.

    2. Disconnect the D2 ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      D56-13 (SLU+) - D2-76 (SLU+) Always Below 1 Ω
      D56-14 (SLU-) - D2-61 (SLU-) Always Below 1 Ω
      D56-13 (SLU+) or D2-76 (SLU+) - Body ground and other terminals Always 10 kΩ or higher
      D56-14 (SLU-) or D2-61 (SLU-) - Body ground and other terminals 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
      Shift solenoid valve SLU connector terminal 1 - terminal 2 20°C (68°F) 5.0 to 5.6 Ω

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

      OK
      Valve moves and makes operating sound.
