PROCEDURE


  1. INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLP)


    1. A01QPFJC11
      *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
      3 (SLP+) - 9 (SLP-) 20°C (68°F) 5.0 to 5.6 Ω
      3 (SLP+) - Body ground and other terminals Always 10 kΩ or higher
      9 (SLP-) - Body ground and other terminals Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG

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


    1. A01QPVYC07
      *a

      Front view of wire harness connector

      (to ECM)

      Disconnect the ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      B93-39 (SLP+) - B93-38 (SLP-) 20°C (68°F) 5.0 to 5.6 Ω
      B93-39 (SLP+) - Body ground and other terminals Always 10 kΩ or higher
      B93-38 (SLP-) - Body ground and other terminals Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG
