PROCEDURE


  1. INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLU)


    1. A0030OTC07
      *a

      Component without harness connected

      (Transmission Wire)

      Disconnect the B185 transmission wire connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      6 (SLU+) - 13 (SLU-) 20°C (68°F) 5.0 to 5.6 Ω
      6 (SLU+) - Body ground and other terminals Always 10 kΩ or higher
      13 (SLU-) - Body ground and other terminals Always 10 kΩ or higher

    3. Connect the B185 transmission wire connector.

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


    1. Disconnect the B208 ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      B208-3 (SLU+) - B208-2 (SLU-) 20°C (68°F) 5.0 to 5.6 Ω
      B208-3 (SLU+) - Body ground and other terminals Always 10 kΩ or higher
      B208-2 (SLU-) - Body ground and other terminals Always 10 kΩ or higher

    3. Connect the B208 ECM connector.

      Result
      Proceed to
      OK
      NG
