    1. A017F3RE04

      Connect the transmission control switch connector of shift lock control unit assembly.

    2. Disconnect the ECM connector.

    3. Measure the voltage according to the value(s) in the table below when the shift lever is moved to each position.

      Standard voltage
      Tester Connection Shift Position Specified Condition

      D55-24 (S) -

      Body ground

      		 S, "+" and "-" 11 to 14 V
      ↑ Except S, "+" and "-" Below 1 V
    4. A017F3RE06

      Turn the ignition switch off.

    5. Measure the resistance according to the value(s) in the table below when the shift lever is moved to each position.

      Standard resistance
      Tester Connection Shift Position Specified Condition
      D55-16 (SFTU) - Body ground Press continuously "+" (Up shift) Below 1 Ω
      ↑ S 10 kΩ or higher
      D55-22 (SFTD) - Body ground Press continuously "-" (Down shift) Below 1 Ω
      ↑ S 10 kΩ or higher
