      *a Component without harness connected
      (Transmission Wire)
    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      B39-1 (OIL) - B39-2 (E2) Always 79 Ω to 156 kΩ
      B39-1 (OIL) or B39-2 (E2) - Other terminals Always 10 kΩ or higher

      HINT: 

      If the resistance is out of the specified range at any of the ATF temperatures shown in the table below, the driveability of the vehicle may decrease.

      ATF Temperature Specified Condition
      10°C (50°F) 5 to 8 kΩ
      25°C (77°F) 2.5 to 4.5 kΩ
      110°C (230°F) 0.22 to 0.28 kΩ

      Result

      Proceed to
      OK
      NG

    Result: 

    NG 

    REPLACE TRANSMISSION WIRE (ATF TEMPERATURE SENSOR). Refer to  REMOVAL [11/2021 - ] 

    Result: 

    OK 

    See step  2

  2. CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM) 
    1. Disconnect the B51 ECM connector.
    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      B51-40 (THO1) - B51-41 (ETHO) Always 79 Ω to 156 kΩ
      B51-40 (THO1) or B51-41 (ETHO) - 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. REPLACE ECM
