PROCEDURE

  1. INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLU)

    1. C264597C07

      *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-)

      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.
