PROCEDURE

  1. INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLU)

    1. C298188C09

      *a

      Component without harness connected

      (Transmission Wire)

      Disconnect the transmission wire connector.

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

      Standard Resistance

      Tester Connection

      Condition

      Specified Condition

      4 (SLU+) - 11 (SLU-)

      20°C (68°F)

      5.0 to 5.6 Ω

      4 (SLU+) - Body ground and other terminals

      Always

      10 kΩ or higher

      11 (SLU-) - Body ground and other terminals

      Always

      10 kΩ or higher

    Result
