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

      Standard Resistance

      Tester Connection Condition Specified Condition
      B77-3 (SL) - Body ground 20°C (68°F) 11 to 15 Ω

    Result: 

    OK 

    REPLACE ECM:  REMOVAL [12/2012 - ] 

    Result: 

    NG 

    See step  2

  2. CHECK HARNESS AND CONNECTOR (WIRING HARNESS CONNECTOR - ECM) 
    1. Disconnect the B78 wiring harness connector.
    2. Disconnect the B77 ECM connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      B78-6 (SL) - B77-3 (SL) Always Below 1 Ω
      B78-6 (SL) or B77-3 (SL) - Body ground and other terminals Always 10 kΩ or higher

    Result: 

    NG 

    REPAIR OR REPLACE HARNESS OR CONNECTOR 

    Result: 

    OK 

    See step  3

  3. INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SL) 
    1. Remove the wiring harness connector.

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

      Standard Resistance

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

    Result: 

    OK 

    REPLACE WIRING HARNESS CONNECTOR:  REMOVAL [12/2012 - 08/2017]  ,  REMOVAL [08/2017 - ] 

    Result: 

    NG 

    See step  4

  4. INSPECT SHIFT SOLENOID VALVE SL 
    1. Remove shift solenoid valve SL.
      GTY373506Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
      *1 Shift Solenoid Valve SL
    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      Shift solenoid valve SL connector terminal - Shift solenoid valve SL body 20°C (68°F) 11 to 15 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 (+) → Shift solenoid valve SL connector
      • Battery negative (-) → Shift solenoid valve SL body
      		 Valve moves and makes an operating noise

    Result: 

    OK 

    REPLACE TRANSMISSION WIRE:  REMOVAL [12/2012 - ] 

    Result: 

    NG 

    REPLACE SHIFT SOLENOID VALVE SL:  DISASSEMBLY [12/2012 - ]
