    Standard resistance (Check for short) 

    TESTER CONNECTION SPECIFIED CONDITION CHART

    Tester Connection Condition Specified Condition
    B31-57 (SLU+) - Body ground Always 10 kΩ or higher
    B31-77 (SLU-) - Body ground Always

    NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: REPLACE ECM (for 2ZR-FE)  (See REMOVAL )

  3. INSPECT SHIFT SOLENOID VALVE SLU 
    1. Remove the shift solenoid valve SLU.
    2. Measure the resistance according to the value(s) in the table below.

      Standard resistance 

      TESTER CONNECTION SPECIFIED CONDITION CHART

      Tester Connection Condition Specified Condition
      1-2 20°C (68°F) 5.0 to 5.6 Ω
    3. Connect the positive (+) lead with a 21 W bulb to terminal 2 and the negative (-) lead to terminal 1 of the solenoid valve connector, then check the movement of the valve.

      OK: 

      The solenoid makes an operating sound. 

      NG: REPLACE SHIFT SOLENOID VALVE SLU  (See DISASSEMBLY )
