      *a Component with harness connected
      (Shift Lock Control ECU)

      HINT: 

      Measure the voltage of the connector.

      Standard Voltage

      Tester Connection Switch Condition Specified Condition
      6 (STP) - 3 (E) Brake pedal depressed 10 to 14 V
      6 (STP) - 3 (E) Brake pedal released Below 1 V
      12 (IG) - 3 (E) Engine switch on (IG) 10 to 14 V
      12 (IG) - 3 (E) Engine switch off Below 1 V

      If the result is not as specified, replace the shift lock control ECU.

    2. Disconnect the shift lock solenoid connector from the shift lock control ECU.

      *a Component without harness connected
      (Shift Lock Control ECU)
    3. Measure the voltage according to the values in the table below.

      HINT: 

      Do not disconnect the shift lock control ECU connector.

      Standard Voltage

      Tester Connection Switch Condition Specified Condition
      1 (SLS+) - 2 (SLS-) Engine switch off Below 1 V
      1 (SLS+) - 2 (SLS-) Engine switch on (IG) Below 1 V
      1 (SLS+) - 2 (SLS-) Engine switch on (IG) and brake pedal depressed 11 to 14 V

      If the result is not as specified, replace the shift lock control ECU.

  2. INSPECT SHIFT LOCK SOLENOID 
    1. Disconnect the shift lock solenoid connector from the shift lock control ECU.

      *a Component without harness connected
      (Shift Lock Solenoid)
    2. Measure the resistance according to the values in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      1 (SLS+) - 2 (SLS-) Battery voltage not applied 101 to 123 Ω
      3 (E2) - 4 (P) Shift position P 10 kΩ or higher
      3 (E2) - 4 (P) Shift position not P Below 1 Ω

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

    3. Apply 12 V battery voltage to the shift lock solenoid valve and check that the valve moves and makes an operating noise.

      OK

      Measurement Condition Specified Condition
      Battery positive (+) → Terminal 1 (SLS+)
      Battery negative (-) → Terminal 2 (SLS-)
      Solenoid moves and makes an operating noise

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

  3. INSPECT TRANSMISSION CONTROL SWITCH 
    1. Measure the resistance according to the value(s) in the table below.

      *a Component without harness connected
      (Transmission Control Switch)

      Standard Resistance

      Tester Connection Condition Specified Condition
      3 (IG) - 7 (S) Shift position S Below 1 Ω
      3 (IG) - 7 (S) Shift position not S 10 kΩ or higher
      2 (SFTU) - 5 (E) Shift lever continuously shifted to "+" position (Up-shift) Below 1 Ω
      2 (SFTU) - 5 (E) Shift position S 10 kΩ or higher
      1 (SFTD) - 5 (E) Shift lever continuously shifted to "-" position (Down-shift) Below 1 Ω
      1 (SFTD) - 5 (E) Shift position S 10 kΩ or higher

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