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

      Standard Resistance

      Tester Connection Condition Specified Condition
      12 (SLU+) - 4 (SLU-) 20°C (68°F) 5.0 to 5.6 Ω
      12 (SLU+) - Body ground Always 10 kΩ or higher
      4 (SLU-) - Body ground Always 10 kΩ or higher

      Result

      Proceed to
      OK
      NG

    Result: 

    NG 

    See step  3

    Result: 

    OK 

    See step  2

  2. CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM) 
    1. Disconnect the F87 ECM connector.
    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      F87-76 (SLU+) - F87-61 (SLU-) 20°C (68°F) 5.0 to 5.6 Ω
      F87-76 (SLU+) - Body ground Always 10 kΩ or higher
      F87-61 (SLU-) - Body ground Always 10 kΩ or higher

      Result

      Proceed to
      OK
      NG

    Result: 

    OK 

    REPLACE ECM. Refer to  COMPONENTS [11/2017 - ] 

    Result: 

    NG 

    REPAIR OR REPLACE HARNESS OR CONNECTOR 

  3. INSPECT SHIFT SOLENOID VALVE SLU 
    1. Remove the shift solenoid valve SLU.

      *1 Shift Solenoid Valve SLU

      Refer to DISASSEMBLY [09/2014 - ]

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

      Standard Resistance

      Tester Connection Condition Specified Condition
      1 - 2 20°C (68°F) 5.0 to 5.6 Ω
    3. Connect a positive (+) lead from the battery with a 21 W bulb to terminal 2 and a negative (-) lead to terminal 1 of the shift solenoid valve connector, then check the movement of the valve.

      OK

      The solenoid makes an operating sound.

      Result

      Proceed to
      OK
      NG

    Result: 

    OK 

    REPAIR OR REPLACE TRANSMISSION WIRE. Refer to  COMPONENTS [09/2014 - ] 

    Result: 

    NG
