    NG: REPLACE TRANSMISSION CONTROL SWITCH 

    OK: Go to next step 

  4. CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - ECM) 
    1. Connect the transmission control switch connector of shift lock control unit assembly.
    2. Disconnect the ECM connector.
    3. Turn the engine switch on (IG) position, and measure the voltage according to the value (s) in the table below when the shift lever is moved to each position.

      Voltage

    4. Turn the engine switch off position.
    5. Disconnect the ECM connector.
    6. Measure the resistance according to the value (s) in the table below when the shift lever is moved to each position.

      Resistance 

      RESISTANCE SPECIFICATION

      Shift Position Tester Connection Specified Condition
      Press continuously
      "+"
      (Up shift)      		 A7 - 30 (SFTU) - Body ground Below 1 Ω
      S ↑ 10 kΩ or higher
      Press continuously
