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

      Standard Resistance

      Tester Connection Condition Specified Condition
      13 (SLU+) - 5 (SLU-) 20°C (68°F) 5.0 to 5.6 Ω
      13 (SLU+) - Body ground Always 10 kΩ or higher
      5 (SLU-) - Body ground Always 10 kΩ or higher
      TEXT IN ILLUSTRATION

      *a Component without harness connected
      (Transmission Wire)

    Result: 

    NG 

    See step  3

    Result: 

    OK 

    See step  2

  2. CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM) 
    1. Disconnect the B37 ECM connector.

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

      Standard Resistance

      Tester Connection Condition Specified Condition
      B37-35 (SLU+) - B37-36 (SLU-) 20°C (68°F) 5.0 to 5.6 Ω
      B37-35 (SLU+) - Body ground Always 10 kΩ or higher
      B37-36 (SLU-) - Body ground Always 10 kΩ or higher
      TEXT IN ILLUSTRATION

      *a Rear view of wire harness connector
      (to ECM)

    Result: 

    OK 

    REPLACE ECM. Refer to  REMOVAL [08/2015 - ] 

    Result: 

    NG 

    REPAIR OR REPLACE HARNESS OR CONNECTOR 

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

    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. Apply 12 V battery voltage to the shift solenoid valve and check that the valve moves and makes an operating noise.

      OK

      Measurement Condition Specified Condition
      • Battery positive (+) with a 21 W bulb → Terminal 2
      • Battery negative (-) → Terminal 1
      Valve moves and makes operating noise

      *a Component without harness connected
      (Shift Solenoid Valve SLU)

    Result: 

    OK 

    REPAIR OR REPLACE TRANSMISSION WIRE. Refer to  REMOVAL [08/2015 - ] 

    Result: 

    NG 

    REPLACE SHIFT SOLENOID VALVE SLU. Refer to  PROCEDURE - Step 2
