    3. Measure the resistance.

      Standard resistance 

      STANDARD RESISTANCE SPECIFICATION

      Tester Connection Specified Condition
      Solenoid Connector (S2) - Solenoid Body (S2) 11 to 15 Ω at 20°C (68°F)
    4. Connect the positive (+) lead to the terminal of the solenoid connector and the negative (-) lead to the solenoid body to check the solenoid valve operation.

      OK: 

      The solenoid makes operating sounds. 

    NG: REPLACE SHIFT SOLENOID VALVE S2 (See  DISASSEMBLY   ) 

    OK: REPAIR OR REPLACE TRANSMISSION WIRE (See  REMOVAL   )
