        *a Front view of wire harness connector
        (to Shift Lock Control ECU)

        Standard Voltage

        Tester Connection Condition Specified Condition
        4 (STP) - Body ground Brake pedal depressed 11 to 14 V
        Brake pedal released Below 1 V
        5 (IG) - Body ground Engine switch on (IG) 11 to 14 V
        Engine switch off Below 1 V

        If the result is not as specified, repair or replace the shift lock control ECU wire harness.

      3. Measure the resistance according to the value(s) in the table below.

        Standard Resistance

        Tester Connection Condition Specified Condition
        1 (E) - Body ground Always Below 1 Ω

        *a Front view of wire harness connector
        (to Shift Lock Solenoid)

        Standard Resistance

        Tester Connection Condition Specified Condition
        4 (P) - 3 (E2) Shift lever in P 10 kΩ or higher
        Shift lever not in P Below 1 Ω

        If the result is not as specified, replace the transmission floor shift assembly.

        If the shift lock does not operate when the power source of the transmission floor shift assembly is normal and the resistance between body ground and the shift lock solenoid is as specified, replace the transmission floor shift assembly.

      3. Measure the resistance according to the value(s) in the table below.

        (to Shift Lock Solenoid)

        Standard Resistance

        Tester Connection Condition Specified Condition
        1 (SLS+) - 2 (SLS-) Always 112 Ω

        If the result is not as specified, replace the transmission floor shift assembly.

        If the shift lock does not operate when the power source of the transmission floor shift assembly is normal and the resistance between body ground and the shift lock solenoid is as specified, replace the transmission floor shift assembly.

  2. INSPECT TRANSMISSION CONTROL SWITCH (w/o Shift Paddle Switch) 
    1. Disconnect the transmission control switch connector.

      Standard Resistance

      Tester Connection Condition Specified Condition
      4 (IG) - 5 (S) Shift lever in S, "+" or "-" Below 1 Ω
      Shift lever not in S, "+" or "-" 10 kΩ or higher
      3 (SFTU) - 2 (E) Shift lever held in "+"
      (Up-shift)      		 Below 1 Ω
      Shift lever not held in "+" 10 kΩ or higher
      1 (SFTD) - 2 (E) Shift lever held in "-"
      (Down-shift)      		 Below 1 Ω
      Shift lever not held in "-" 10 kΩ or higher

      If the result is not as specified, replace the transmission floor shift assembly.
