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

      Standard Resistance

      Tester Connection Condition Specified Condition
      B77-15 (SLT+) - B77-14 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω
      B77-15 (SLT+) - Body ground and other terminals Always 10 kΩ or higher
      B77-14 (SLT-) - Body ground and other terminals Always 10 kΩ or higher

      Result

      Proceed to
      OK
      NG

    Result: 

    OK 

    REPLACE ECM. Refer to  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
      B78-15 (SLT+) - B77-15 (SLT+) Always Below 1 Ω
      B78-7 (SLT-) - B77-14 (SLT-) Always Below 1 Ω
      B78-15 (SLT+) or B77-15 (SLT+) - Body ground and other terminals Always 10 kΩ or higher
      B78-7 (SLT-) or B77-14 (SLT-) - Body ground and other terminals Always 10 kΩ or higher

      Result

      Proceed to
      OK
      NG

    Result: 

    NG 

    REPAIR OR REPLACE HARNESS OR CONNECTOR 

    Result: 

    OK 

    See step  3

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

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

      Standard Resistance

      Tester Connection Condition Specified Condition
      A-12 (SLT+) - A-7 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω
      A-12 (SLT+) - Body ground and other terminals Always 10 kΩ or higher
      A-7 (SLT-) - Body ground and other terminals Always 10 kΩ or higher

      Result

      Proceed to
      OK
      NG

    Result: 

    OK 

    REPLACE WIRING HARNESS CONNECTOR. Refer to  REMOVAL [12/2012 - 08/2017]  or  REMOVAL [08/2017 - ] 

    Result: 

    NG 

    See step  4

  4. INSPECT SHIFT SOLENOID VALVE SLT 
    1. Remove shift solenoid valve SLT.

      *1 Shift Solenoid Valve SLT
    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 1
      • Battery negative (-) → Terminal 2
      		 Valve moves and makes an operating noise

      Result

      Proceed to
      OK
      NG

    Result: 

    OK 

    REPLACE TRANSMISSION WIRE. Refer to  REMOVAL [12/2012 - ] 

    Result: 

    NG 

    REPLACE SHIFT SOLENOID VALVE SLT. Refer to  DISASSEMBLY [12/2012 - ]
