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

      Standard Resistance

      Tester Connection Condition Specified Condition
      6 (SR) - Body ground 20°C (68°F) 11 to 15 Ω

      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 F102 ECM connector.
    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition

      *1 Shift Solenoid Valve SR

      Refer to DISASSEMBLY [04/2013 - ]

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

      Standard Resistance

      Tester Connection Condition Specified Condition
      Terminal of shift solenoid valve SR connector - Shift solenoid valve SR body 20°C (68°F) 11 to 15 Ω
    3. Connect a positive (+) lead from the battery to the terminal of the shift solenoid valve connector, and a negative (-) lead to the shift solenoid valve body. Check that the valve moves and makes an operating sound.

      OK

      Valve moves and makes an operating sound.

      Result

      Proceed to
      OK
      NG

    Result: 

    OK 

    REPAIR OR REPLACE TRANSMISSION WIRE. Refer to  COMPONENTS [04/2013 - ] 

    Result: 

    NG 

    REPLACE SHIFT SOLENOID VALVE SR. Refer to  COMPONENTS [04/2013 - ]
